DETAILED DESCRIPTION

In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. For example, the first value and the second value are only used to distinguish different values, and their order is not limited. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

It should be noted that, in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

In the present application, "at least one" means one or more, and "plurality" means two or more. "And/or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character "/" generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, a and b, a and c, b and c, or a, b and c, where a, b, c can be single or multiple.

The cellular communication capability is provided by a modem processor (Modem), which runs on a baseband chip plus a coprocessor. The Modem can support the device to implement a series of cellular communication functions (or cellular communication capabilities) such as SMS sending and receiving functions, 5G-related functions, call making functions, call answering functions, data service Internet access capabilities, subscriber identification module (SIM) reading capabilities, and one-click application login capabilities. Exemplarily, when a user uses a device with cellular communication capabilities, he can implement a series of cellular communication functions by triggering a local application; or, when a device with cellular communication capabilities shares the cellular communication capabilities with a device without cellular communication capabilities, the device without cellular communication capabilities can also use the Modem in the device with cellular communication capabilities to implement the above series of cellular communication functions.

In some scenarios, when a device with cellular communication capabilities has shared its cellular communication capabilities with a device without cellular communication capabilities (i.e., has shared the modem of the device with cellular communication capabilities), the device without cellular communication capabilities can use all cellular communication capabilities of the device with cellular communication capabilities based on the modem in the device with cellular communication capabilities, i.e., can use all cellular communication functions.

Generally, in different business scenarios, users may need different cellular communication capabilities. For example, when a device with cellular communication capabilities, such as a mobile phone, has shared its cellular communication function with a device without cellular communication capabilities, such as a tablet, when a user uses the tablet to play games or take online classes, he or she may not need to be affected by external factors, such as receiving text messages and answering calls provided by the mobile phone; or when the user rests at night, he or she may not need the data service Internet access function provided by the mobile phone.

However, since the device does not have cellular communication capabilities, it is impossible to achieve unified management and control of all cellular communication capabilities in different business scenarios, making the flexibility of using cellular communication functions poor. Therefore, on the basis of being able to use all cellular communication capabilities, the device also needs to support independent management of various cellular communication functions, so that each cellular communication function can be dynamically and independently opened and closed for sharing.

In view of this, an embodiment of the present application provides a method for using a cellular communication function, which can subdivide various types of cellular communication capabilities and share them independently. At the same time, it can match appropriate cellular communication capabilities according to different usage scenarios of users, enhance the intelligence of cellular communication sharing, and reduce unnecessary standby power consumption.

In order to clearly describe the following embodiment of the use process of the cellular communication function proposed in the present application, a brief introduction to the technology related to the embodiment of the present application is first given:

The proxy scenario is a design pattern that provides additional access to a target object by creating a proxy object of the target object. The target object is an interface, such as a hardware abstraction layer interface definition language (HIDL) interface. By accessing the target object through a proxy object, additional functional operations can be provided through the proxy object to extend the functionality of the original target object without modifying the original target object. In short, the proxy pattern is to set a proxy object as an intermediate proxy to control access to the original target object, so as to enhance the functionality of the original target object and simplify the access process.

In a scheme in which an electronic device with cellular communication capability uses a local cellular communication function, an application in the application layer of the electronic device with cellular communication capability triggers a request for a cellular communication service, and the request for the cellular communication service is sent from the local application layer to the local application framework layer, and then the local application framework layer calls the HIDL interface on the local system library, and then sends the request for the cellular communication service to the local Modem (Modem) for processing through the local HIDL interface. After processing, the local Modem obtains the response data corresponding to the request for the cellular communication service, and then reports the response data corresponding to the cellular service request to the local application framework layer through the HIDL interface of the local system library, and then the application framework layer sends it to the application corresponding to the response data. The local Modem also actively reports the cellular communication service to the application framework layer through the local HIDL interface, and then the application framework layer continues to report the cellular communication service to the application corresponding to the cellular communication service. Exemplarily, all services or capabilities related to cellular communication can be called cellular communication services, such as calls, text messages, SIM card changes, call forwarding, etc., which can all be called cellular communication services.

Among them, the HIDL interface mentioned in the solution for an electronic device with cellular communication capability to use the local cellular communication function can be divided into three categories according to the calling direction: the first calling direction is the calling direction in which the request for cellular communication service on the application side where the application layer and the application framework layer are located is actively sent to the modem side, the second calling direction is the direction in which the modem side reports the response data corresponding to the request for cellular communication service initiated by the application side to the application side, and the third calling direction is the direction in which the modem side actively reports the notification of cellular communication service to the application side.

The following describes the use scenario of the method for using the cellular communication function provided in the embodiment of the present application. For example, FIG1 is a schematic diagram of a scenario provided in the embodiment of the present application, and the method for using the cellular communication function provided in the embodiment of the present application can be applied to the scenario shown in FIG1 .

As shown in FIG1 , the device with cellular communication capability (or referred to as the second device) may be the mobile phone 11 in FIG1 . The device without cellular communication capability (or referred to as the first device) may be a smart device such as the tablet 12, smart glasses 13, smart watch 14, smart speaker 15, smart screen 16, or laptop computer 17 in FIG1 . As shown in FIG1 , the mobile phone 11 may establish connections with the tablet 12, smart glasses 13, smart watch 14, smart speaker 15, smart screen 16, and laptop computer 17, respectively, and provide the cellular communication capability of the mobile phone 11 to the tablet 12, smart glasses 13, smart watch 14, smart speaker 15, smart screen 16, and laptop computer 17. In other embodiments, the mobile phone 11 can also provide the cellular communication capabilities of the mobile phone 11 to devices such as media players (such as MP3, MP4, etc.), ultra-mobile personal computers (UMPC), personal digital assistants (PDA), wireless headphones, smart bracelets, wireless car-mounted, augmented reality (AR)/virtual reality (VR) devices or televisions.

As shown in FIG1 , after the mobile phone 11 establishes a connection with other smart devices in FIG1 , it provides its own cellular communication capabilities to other smart devices, so that other smart devices that do not have cellular communication capabilities, such as the tablet 12, smart glasses 13, smart watches 14, smart speakers 15, smart screens 16, and laptops 17, can use the cellular communication capabilities of the mobile phone 11 to achieve all cellular communication functions. For example, the tablet 12 can obtain the status of the cellular communication network in the mobile phone 11, and then the tablet 12 can automatically choose to use a wireless network or a cellular communication network to access the Internet according to the status of the cellular communication network. For another example, the smart screen 16 can use the SIM card in the mobile phone 11 to make and receive calls.

For example, Fig. 2 is a schematic diagram of another scenario provided by an embodiment of the present application. In a possible implementation, the method for using the cellular communication function provided by an embodiment of the present application can also be applied to the scenario shown in Fig. 2 .

As shown in FIG2 , the first device may be a mobile phone 21, and the second device may be a mobile phone 22 and a mobile phone 23. The mobile phone 21 establishes connections with multiple mobile phones such as the mobile phone 22 and the mobile phone 23, and the mobile phone 22 and the mobile phone 23 both provide cellular communication capabilities to the mobile phone 21, and the mobile phone 21 can use the cellular communication capabilities of the mobile phone 22 and the mobile phone 23. For example, the mobile phone 21 can use any SIM card of the mobile phone 22 and the mobile phone 23 to make and receive calls, and can also arbitrarily choose to use the cellular communication network of the mobile phone 22 and the mobile phone 23 to access the Internet.

In some embodiments, the first device may also be a mobile phone, tablet computer, desktop, laptop, notebook computer, ultra-mobile personal computer (UMPC), handheld computer, netbook, personal digital assistant (PDA), wearable electronic device, smart watch and other electronic devices, and the second device is a mobile phone, smart call watch and other electronic devices with cellular communication capabilities.

The core library consists of two parts: one part is the function that needs to be called by the Java language, and the other part is the Android core library.

Modem5021 is used to process the received request for the cellular communication service, obtain response data corresponding to the request for the cellular communication service, and then send the response data corresponding to the request for the cellular communication service to the distributed cellular communication module 5022.

It should be noted that although the embodiments of the present application are described using the Android system as an example, its basic principles are also applicable to electronic devices based on operating systems such as Hongmeng, iOS or Windows.

As shown in FIG5 , based on the above-mentioned related technologies, an embodiment of the present application proposes a system for using a cellular communication function. The system for using a cellular communication function includes: a first device and a second device, wherein a distributed cellular communication module 5011 and a telephone manager 5012 are provided in the application framework layer of the first device, a distributed cellular communication module 5022 and a telephone manager 5023 are also provided in the application framework layer of the second device, and the second device also has a Modem 5021. A connection is established between the distributed cellular communication module 5011 of the first device and the distributed cellular communication module 5022 of the second device via a distributed bus 5013 of the first device and a distributed bus 5024 of the second device.

In some embodiments, when the second device has shared its own cellular communication capability with the first device (i.e., shared the modem of the second device), the processing process of the request for cellular communication service in the system of FIG. 5 may be: the first device triggers the request for cellular communication service and executes step S5012, the first device sends the request for cellular communication service to the local phone manager, and in step S5013, the phone manager of the first device sends the request for cellular communication service to the local distributed cellular communication module. In step S5014, the distributed cellular communication module of the first device forwards the request for cellular communication service to the distributed cellular communication module of the second device. The second device executes step S5015, the distributed cellular communication module of the second device sends the request for cellular communication service to the local modem of the second device for processing, and the modem of the second device obtains the response data corresponding to the request for cellular communication service.

Exemplarily, the transmission process of the request for cellular communication service in the system can be shown as the solid line path shown in FIG5: the short message application in the application layer of the first device triggers the request for cellular communication service, and the request for cellular communication service can be a short message sending request. The first device executes step S5012 to send the request for cellular communication service triggered by the application layer to the local phone manager 5012. In step S5013, the phone manager 5012 of the first device sends the cellular communication request to the distributed cellular communication module 5011 of the first device. In step S5014, the distributed cellular communication module 5011 of the first device forwards the request for cellular communication service received by the phone manager 5012 of the first device to the distributed cellular communication module 5022 of the second device. In step S5015, the distributed cellular communication module 5022 of the second device sends the request for cellular communication service to the local Modem 5021 for processing. In some embodiments, the distributed cellular communication module 5022 of the second device calls the HALinterface definition language (HIDL) interface through the radio layer interface (RIL) module on the hardware abstraction layer (HAL) of the system library to transmit the request for the cellular communication service to the local Modem 5021 for processing. After the Modem 5021 processes the request for the cellular communication service, it will obtain the response data corresponding to the request for the cellular communication service.

In other embodiments, the request for the cellular communication service of the first device may also be sent to the distributed cellular communication module 5011 without passing through the phone manager 5012. For example, the IP multimedia subsystem (IMS) may directly call the distributed cellular communication module 5011 at the application layer, that is, the request for the cellular communication service is directly sent from the application layer to the distributed cellular communication module 5011. There are many ways for the upper layer application (i.e., the application layer and the application framework layer) to call the distributed cellular communication module, which is not limited in the embodiments of the present application.

In some embodiments, the processing process of the response data corresponding to the request for the cellular communication service in the system of FIG. 5 may be: in step S5021, the modem of the second device sends the response data corresponding to the request for the cellular communication service to the local distributed cellular communication module, and in step S5022, the distributed cellular communication module of the second device sends the response data corresponding to the request for the cellular communication service to the distributed cellular communication module of the first device. In step S5023, the distributed cellular communication module of the first device sends the response data corresponding to the request for the cellular communication service to the local phone manager, and in step S5024, the phone manager of the first device sends the response data corresponding to the request for the cellular communication service to the application that triggers the request for the cellular communication service.

Exemplarily, the transmission path of the response data corresponding to the request for the cellular communication service may be as shown by the dotted line path in FIG. 5 : In step S5021, the Modem 5021 of the second device transmits the response data corresponding to the request for the cellular communication service to the distributed cellular communication module 5022. In some embodiments, when executing step S5021, the Modem 5021 of the second device calls the HIDL interface through the RIL module in the system library to transmit the response data corresponding to the request for the cellular communication service to the distributed cellular communication module 5022. In step S5022, the distributed cellular communication module 5022 transmits the response data corresponding to the request for the cellular communication service to the distributed cellular communication module 5011 of the first device. In step S5023, the distributed cellular communication module 5011 of the first device sends the response data corresponding to the request for the cellular communication service to the phone manager 5012. In step S5024, the phone manager 5012 transmits the response data corresponding to the request for the cellular communication service to the short message application.

It should be noted that there are many ways to establish a communication connection between the distributed bus 5013 of the first device and the distributed bus 5024 of the second device. The communication connection can be established in a wired form or in a wireless form. For example, in Figure 1, when the first device is a tablet 12 and the second device is a mobile phone 11, the mobile phone 11 and the tablet 12 can establish a wireless connection via Bluetooth, and can also establish a communication connection by connecting to the same wireless Wi-Fi. The difference in the way of establishing a communication connection between the first device and the second device does not affect the implementation of the embodiments of the present application.

Since all requests for cellular communication services of the first device can be forwarded to the Modem 5021 of the second device for processing through the distributed cellular communication module 5011 of the first device, and the distributed cellular communication module 5022 of the second device can transmit the response data corresponding to the request for cellular communication services to the first device by sending the response data corresponding to the request for cellular communication services to the distributed cellular communication module 5011 of the first device, the first device can use all cellular communication capabilities of the second device, that is, it can use all cellular communication functions.

In a possible implementation, as shown in FIG. 5 , the telephone manager 5012 may also include: an interface of a development toolkit, a service interface of the telephone manager, and an access interface of a radio interface.

Exemplarily, FIG6 is a schematic diagram of a path of a request for a cellular communication service in the application framework layer provided by an embodiment of the present application. As shown in FIG6 , the sending process of the request for the cellular communication service of the first device in the application framework layer is as follows: the request for the cellular communication service of the first device calls the application programming interface (API) of the Android open source project (Android open source project, AOSP) development kit (Software Development Kit, SDK) in the phone manager through the request for the cellular communication service, and then the AOSP SDK API calls the service interface of the phone manager again, and then the service of the phone manager calls the access interface of the radio interface, and then the access interface of the radio interface sends it to the distributed cellular communication module of the first device, and the distributed cellular communication module of the first device implements the reception of the request for the cellular communication service of the local phone manager. Among them, since the distributed cellular communication module of the first device has pre-created a proxy object of the request interface, it can proxy the access interface of the radio interface and receive the request for the cellular communication service sent to the access interface of the radio interface.

In a possible implementation, as shown in FIG5 , the distributed cellular communication module 5011 of the first device may also be set in the RIL module of the system library; alternatively, the distributed cellular communication module 5022 of the second device may be set in the vendor wireless interface layer (Vendor-RIL) of the system library.

Exemplarily, FIG7 is a schematic diagram of the system architecture of another system for using cellular communication functions provided in an embodiment of the present application. As shown in FIG7 , the distributed cellular communication module 701 of the first device can also be set in the RIL module in the system library, and the distributed cellular communication module 702 of the second device can be set in the vendor radio interface layer (Vendor-RIL) of the system library. In addition, the distributed cellular communication module 701 of the first device can establish a connection with the distributed cellular communication module 702 of the second device.

In some embodiments, the connection between the distributed cellular communication module 701 of the first device and the distributed cellular communication module 702 of the second device may be established through the distributed bus 703 in the first device and the distributed bus 704 in the second device. In addition, in the process of the first device sending a cellular communication capability sharing request to the second device, the first device may not need to create a proxy object of the relevant interface, and the second device may not need to create a proxy object of the relevant interface. By pre-configuring the distributed cellular communication module 701 of the first device in advance, the distributed cellular communication module 701 of the first device can forward the request for the cellular communication service received through the HIDL on the RIL module to the distributed cellular communication module 702 of the second device. By pre-setting the distributed cellular communication module 702 of the second device, the distributed cellular communication module 702 of the second device can forward the response data corresponding to the request for the cellular communication service to the distributed cellular communication module 701 of the first device, and also forward the cellular communication service reported by the local Modem to the distributed cellular communication module of the first device.

As shown in FIG. 7 , since the distributed cellular communication module 701 of the first device is set in the RIL of the system library of the first device, and the distributed cellular communication module 702 of the second device is set in the system library of the second device, when the first device sends a request for a cellular communication service to the second device, the request for the cellular communication service of the first device (for example, a short message sending request) is sent from the application layer of the first device to the phone manager in the application framework layer, and then from the phone manager in the application framework layer to the distributed cellular communication module 701 in the system library, and then through the distributed bus 703 of the first device and the distributed bus 704 of the second device, to the distributed cellular communication module 702 in the system library of the second device. The distributed cellular communication module 702 then sends the request for the cellular communication service to the local modem, as shown by the dotted line path in FIG7 : the modem then sends the response data corresponding to the request for the cellular communication service to the distributed cellular communication module 702, the distributed cellular communication module 702 sends the response data corresponding to the request for the cellular communication service to the distributed cellular communication module 701 of the first device through the distributed bus 704 of the second device and the distributed bus 703 of the first device, and then the distributed cellular communication module 701 of the first device sends the response data corresponding to the request for the cellular communication service to the telephone manager, which then sends it to the corresponding application of the first device.

It should be noted that the principle and execution process of the use of cellular communication capabilities between the first device and the second device in Figure 7 are similar to the principle and execution process of the steps shown in Figure 5 above, which can be referred to and will not be repeated here.

In a possible implementation, as shown in FIG5 , the distributed cellular communication module 5011 of the first device may also be set in the Vendor-RIL of the system library; if applicable, the distributed cellular communication module 5022 of the second device may be set in the Vendor-RIL of the system library.

For example, Figure 8 is a schematic diagram of the system architecture of another system for using cellular communication functions provided in an embodiment of the present application. As shown in Figure 8, the distributed cellular communication module 701 of the first device can also be set in the Vendor-RIL in the system library, and the distributed cellular communication module 702 of the second device can be set in the Vendor-RIL of the system library.

As shown in the implementation path in FIG8 , the request for the cellular communication service of the first device (for example, a short message sending request) is sent from the application layer of the first device to the phone manager in the application framework layer, and then from the phone manager in the application framework layer to the RIL module in the system library, and then from the RIL module to the distributed cellular module 501, and then through the distributed bus 703 of the first device and the distributed bus 704 of the second device, to the distributed cellular communication module 702 in the system library of the second device, and the distributed cellular communication module 702 then sends the request for the cellular communication service to the local Modem, as shown in the dotted line path in FIG8 : the Modem then sends the response data corresponding to the request for the cellular communication service to the distributed cellular communication module 702, and the distributed cellular communication module 702 sends the response data corresponding to the request for the cellular communication service to the distributed cellular communication module 701 of the first device through the distributed bus 704 of the second device and the distributed bus 703 of the first device, and then the distributed cellular communication module 701 of the first device sends the response data corresponding to the request for the cellular communication service to the RIL module, and the RIL module continues to send it to the phone manager, and then the phone manager sends it to the corresponding application of the first device. The transmission path of the cellular communication service is consistent with the dotted line path shown in FIG8 , and will not be described again here.

It should be noted that the principle and execution process of the use of cellular communication capabilities between the first device and the second device in Figure 8 are similar to the principle and execution process of the steps shown in Figure 7 above, so please refer to them and will not be repeated here.

Based on the system architecture shown in FIG. 5 , the use process of the cellular communication function between the first device and the second device in the embodiment of the present application will be described below in detail in conjunction with FIG. 9 .

For example, Figure 9 is a flowchart of a method for using a cellular communication function provided in an embodiment of the present application. Take the case where both the first device and the second device are electronic devices running the Android operating system, where the first device is a demander (or user) of cellular communication capabilities, and the second device is a provider of cellular communication capabilities.

In the embodiment of the present application, as shown in FIG5 , the distributed cellular communication module 5011 of the first device and the distributed cellular communication module 5022 of the second device can be preset with a configuration file, and the configuration file can be preset with scene information, cellular communication functions, and the corresponding relationship between interfaces. Among them, the scene information can include one or more of the following: work scene, game scene, power saving scene, sleep scene, or boarding scene, etc.; the cellular communication function corresponding to any scene can include one or more of the following: basic public function, calling call function, called call function, SMS sending and receiving function, SIM card reading function, or data service Internet access function, etc.; the interface corresponding to any cellular communication function can include one or more of the following: request interface (such as the interface corresponding to the request of cellular communication service), or reporting interface (such as the interface corresponding to the notification of cellular communication service, or the interface corresponding to the response message of cellular communication service), etc.

It is understandable that the embodiments of the present application can support customization of the scenario information and the cellular communication function, and can also support updating of the scenario information and the cellular communication function, and the method for using the cellular communication function provided in the embodiments of the present application is not limited to the above-mentioned scenarios and cellular communication functions. For example, the scenario information and the cellular communication function can be updated by updating the configuration file in the distributed cellular communication module of the device, so that the first device and the second device can implement different cellular communication functions in different scenarios based on the updated configuration file.

As shown in FIG9 , the method for using the cellular communication function may specifically include the following steps:

S901. The second device enables a cellular communication capability sharing function.

The cellular communication capability sharing function refers to the function of sharing the local modem with other devices. Since the modem can provide cellular communication capability, sharing the local modem with other devices means sharing the cellular communication capability with other devices. The second device in the embodiment of the present application refers to an electronic device with cellular communication capability.

In some embodiments, in response to the user's operation, the second device enables the cellular communication capability sharing function. In other embodiments, the second device may enable the cellular communication capability sharing function through the distributed cellular communication module of the second device. The distributed cellular communication module of the second device may be arranged in the application framework layer of the second device as shown in the distributed cellular communication module 5022 shown in FIG. 5. In other embodiments, step S901 may be performed by one or more modules in the second device, and the modules that perform step S901 may be located in different framework layers in the second device.

In some embodiments, when the distributed cellular communication module of the second device turns on the cellular communication capability sharing function, the second device is in a state that can be discovered by other devices. When other devices discover the second device, they can know that the current cellular communication capability sharing function of the second device is turned on and can be shared and used by other devices. There are many ways to make the second device in a state that can be discovered by other devices. For example, the second device can be discovered by other devices that turn on Bluetooth when Bluetooth is turned on, can be discovered by other devices in the local area network when the second device is connected to the local area network, can be discovered by other devices in the near-field network (such as a wireless network) when the second device is connected to the near-field network, can be discovered by other devices in the near-field network, can be discovered by other devices under the second device account when the second device logs in to the account, and so on.

In some embodiments, the power-on operation of the second device may trigger the distributed cellular communication module of the second device to execute the cellular communication capability sharing function, or the cellular communication capability sharing function may be turned on by default after the second device is turned on, or the user may click the switch button on the second device interface to turn on the cellular communication capability, which is not limited in the embodiments of the present application. For example, as shown in a in Figure 11, the cellular communication sharing setting interface has a switch button for cellular communication capability, and when the user operates the switch button 1101 to the interface shown in a in Figure 11, the cellular communication capability sharing function is turned on. The user's operation instruction of the switch button to turn on the cellular communication capability is transmitted to the distributed cellular communication module of the second device in the application framework layer through the application layer, so as to trigger the distributed cellular communication module of the second device to turn on the cellular communication capability sharing function.

In a possible implementation, step S901 may not be performed, and the second device may enable the cellular communication capability sharing function by default, or automatically enable the cellular communication capability sharing function when a specific condition is detected. For example, the specific condition may be detecting a device of the same brand nearby, or a server notification to enable the function.

S902: The first device queries the network for devices that have enabled a cellular communication capability sharing function.

The first device has a function of discovering devices, and devices with the cellular communication capability sharing function enabled in the network can be discovered by the first device. In some embodiments, after the first device queries the devices with the cellular communication capability sharing function enabled in the network, it can also be displayed on the interface of the first device for the user to select. For example, the interface shown in a of Figure 11 shows the available cellular communication devices (i.e., devices with the cellular communication capability sharing function enabled in the network) on the device discovery interface. If device 1 and device 2 are both devices with the cellular communication capability sharing function enabled in the network, as shown by the button switch 1102, it means that the user does not use the cellular communication capability of device 1, and as shown by the switch button 1103, it means that the user selects the cellular communication capability of device 2.

In some embodiments, the user can choose to connect device 1 and device 2 at the same time, and the user can use the cellular communication capabilities of at least two devices at the same time. For example, if device 1 is equipped with a telecom card and device 2 is equipped with a mobile card, the user can use the cellular communication capabilities of device 1 and device 2 on the devices at the same time, that is, use the telecom and mobile cards at the same time.

In some embodiments, the first device may perform step S902 through a distributed cellular communication module of the first device. The distributed cellular communication module of the first device may be set in the application framework layer of the first device as shown in FIG5 . The distributed cellular communication module of the first device may query the device with Bluetooth turned on and the cellular communication capability sharing function turned on through the Bluetooth discovery function of the first device, or may query the device with the cellular communication capability sharing function turned on in the local area network where the first device is located, or may query the device with the cellular communication capability sharing function turned on in the near field network where the first device is located, or may query other devices under the login account of the first device.

In some embodiments, the distributed cellular communication module of the first device can discover devices with the cellular communication capability sharing function enabled in a near-field network, a local area network, or a far-field network through a distributed bus in the first device, and then query the devices with the cellular communication capability sharing function enabled in the network. For example, the distributed cellular communication module of the first device can discover devices with the cellular communication capability sharing function enabled under the same account in the far-field network through a distributed bus.

In some embodiments, the first device and the second device may establish a communication connection via a wired manner; or, the first device and the second device may also establish a communication connection via a wireless manner, for example, the first device and the second device establish a communication connection via Bluetooth, WIFI, or wireless means such as connecting to the same cloud account. The manner in which the first device and the second device establish a communication connection is not limited in the embodiments of the present application.

It is understandable that the first device and the second device can implement various modes of the above communication connection through a distributed bus. In a possible implementation, as shown in FIG5 , the above communication connection mode can be implemented through a distributed bus 5013 of the first device and a distributed bus 5024 of the second device.

In some embodiments, step S902 can be triggered by a user. Specifically, the user executes an operation to query the devices in the network that have enabled the cellular communication capability sharing function through the display interface of the first device. The distributed cellular communication module of the first device responds to the user's operation and executes step S902. The first device may also automatically trigger the execution of step S902 when it is turned on. There are many ways to trigger the execution of step S902, including but not limited to the contents proposed in the embodiments of the present application.

Since the second device in the embodiment of the present application executes step S901, when the first device executes step S902, it can query that the second device has enabled the cellular communication capability sharing function, and know that the cellular communication capability of the second device can be shared, that is, the modem of the second device is allowed to be shared with the first device.

S903: The first device selects a second device from all the devices that have enabled the cellular communication capability sharing function.

The second device in the embodiment of the present application refers to a device that needs to use the cellular communication capability of the first device, that is, the first device chooses to use the cellular communication capability of the second device.

The first device may query one or more devices with the cellular communication capability sharing function enabled in step S902. The first device may select a device whose cellular communication capability it wants to use from all the devices with the cellular communication capability sharing function enabled, as the second device.

In some embodiments, one of the devices with the cellular communication capability sharing function enabled can be selected as the second device, that is, the first device only selects to use the cellular communication function of one device. In other embodiments, multiple devices can be selected from all the devices with the cellular communication capability sharing function enabled, and all of them can be used as the second device, that is, the first device can select to use the cellular communication function of each of the multiple devices.

In some embodiments, step S903 may be executed by a distributed cellular communication module of the first device, or may be executed by cooperation of multiple modules in the first device.

In some embodiments, the second device may be automatically selected by the distributed cellular communication module of the first device according to a preconfigured selection rule. The selection rule may be random or arbitrary, may be to give priority to the nearest device, may be to give priority to the device with the strongest signal, etc. There are many ways to set the selection rule, including but not limited to the contents proposed in the embodiments of the present application.

In other embodiments, the first device may be responsive to the user's selection operation, and select the second device from all the devices with the cellular communication capability sharing function enabled. For example, after executing step S902, the distributed cellular communication module of the first device sends all the devices with the cellular communication capability sharing function enabled that have been queried back to the application layer, and displays them on the display interface of the first device. The user then selects the second device from all the devices displayed on the display interface by clicking. For example, in the interface shown in a of FIG. 11 , the user selects device 2 as the second device from the list of available cellular communication devices. Then the first device responds to the user's selection operation and executes step S903, that is, selects the second device specified by the user's selection operation from all the devices with the cellular communication capability sharing function enabled that have been queried. There are many ways for the first device to select the second device, including but not limited to the contents proposed in the embodiments of the present application.

It should be noted that steps S901 to S903 are optional steps. In some embodiments, the second device is preset in advance. When the first device discovers the second device, it can directly establish a connection, that is, directly execute step S904. For example, when the second device and the first device are both powered on, step S904 is directly executed by default, and steps S901 to S903 may not be executed.

S904: The first device sends a socket connection request to the second device.

If you want to establish a socket connection between the first device and the second device, at least a pair of sockets is required, one of which runs on the first device (i.e., the user of cellular communication capabilities) and the other runs on the second device (i.e., the provider of cellular communication capabilities).

In some embodiments, the distributed cellular communication module of the first device may use the socket of the first device to make a socket connection request to the distributed cellular communication module of the second device. The socket connection request describes the socket of the second device to be connected, indicates the address and port number of the socket of the second device, and the socket connection request also describes the socket of the first device itself.

When the first device creates a Socket connection request, it may specify a protocol to be used, such as Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and the like.

S905: The second device establishes a connection with the first device in response to the socket connection request.

After the second device establishes a connection with the first device in response to the socket connection request, communication can be achieved between the first device and the second device.

In some embodiments, after the distributed cellular communication module of the second device receives the socket connection request sent by the first device, it responds to the socket connection request, and then performs some operations to authenticate the connection request, and establishes a connection with the distributed cellular communication module of the first device after the authentication is passed. In some embodiments, the distributed cellular communication module of the second device can establish a connection with the distributed cellular communication module of the first device through a distributed bus. After the distributed cellular communication module of the first device and the distributed cellular communication module of the first device can establish a connection through a distributed bus, the distributed communication bus can maintain the connection channel without disconnection. The distributed bus can also be in a low-power standby mechanism during the process in which the first device and the second device are in a connected state, and is in a working state only when the distributed bus is needed to send work, and is in a low-power standby state at other times. Exemplarily, the distributed cellular communication module of the first device and the distributed cellular communication module of the second device can establish a connection through the distributed bus 5013 and the distributed bus 5024 as shown in Figure 5.

In some embodiments, steps S904 to S905 can be understood as a process of establishing a connection between a distributed cellular communication module of the first device and a distributed cellular communication module of the second device. In addition to establishing the connection through a socket, the connection can also be established through a hardware connection, a wireless network connection, or other network connection protocols. That is, there are many ways to establish a connection between the distributed cellular communication module of the first device and the distributed cellular communication module of the second device, including but not limited to the contents proposed in the embodiments of the present application.

S906: The first device sends a cellular communication capability sharing request to the second device.

After the first device establishes a connection with the second device, it automatically triggers the sending of a cellular communication capability sharing request to the second device. The cellular communication capability sharing request is used to request the second device to share the cellular communication capability of the second device itself, and can also be understood as a request to grant the first device permission to use the modem of the second device.

In some embodiments, the cellular communication capability sharing request may be triggered by the distributed cellular communication module of the first device and sent to the distributed cellular communication module of the second device. In other embodiments, the cellular communication capability sharing request may be sent to the second device with the cooperation of one or more modules in the first device.

In some embodiments, the cellular communication capability sharing request may carry a unique identifier of the first device (eg, the address and port number of the first device) and a unique identifier of the second device (eg, the address and port number of the second device).

In some embodiments, if the distributed cellular communication module of the first device and the distributed cellular communication module of the second device are connected via a distributed bus in step S905, then when the first device executes step S906, the communication capability sharing request is also sent via the distributed bus. In some embodiments, the distributed bus can encrypt and encapsulate the sent data (e.g., the cellular communication capability sharing request) to ensure data security during the sending process.

S907: The first device creates a proxy object of the request interface.

The proxy object of the request interface is used to forward the request for the cellular communication service received locally on the first device to the distributed cellular communication module of the second device.

The request for cellular communication service is a request for executing the cellular communication service function related to the application, such as a text message sending request triggered by a text message application, a phone call making request triggered by a phone application, a phone call answering request, etc. The response data corresponding to the request for cellular communication service is the processing result data after the modem processes the request for cellular communication service. For example, if the request for cellular communication service is a text message sending request, then the response data corresponding to the request for cellular communication service may be a description of whether the text message is sent successfully, the specific reason for the failure of the text message sending, etc.

In some embodiments, the distributed cellular communication module of the first device may be a proxy object of the request interface created. The request interface may be created inside the distributed cellular communication module of the first device.

Specifically, the process of executing step S907 may be: based on the design pattern of the proxy mode, create a proxy object of the request interface. Among them, creating a proxy object of the request interface may be creating a proxy object of the first type of HIDL interface in the scheme for the above-mentioned electronic device with cellular communication capability to use the local cellular communication function. The created proxy object of the request interface has the functions of the first type of HIDL interface mentioned above, and extends other functions. By extending additional functional operations in the proxy object of the request interface, it can be achieved that the proxy object of the request interface can forward the request for the cellular communication service received by the local telephone manager of the first device to the distributed cellular communication module of the second device. It should be noted that the specific principle of the proxy mode can be introduced in the relevant part of the proxy mode mentioned above, which will not be repeated here. For a detailed introduction to the scheme for electronic devices with cellular communication capabilities to use local cellular communication functions, please refer to the relevant part of the scheme for electronic devices with cellular communication capabilities to use local cellular communication functions mentioned above, which will not be repeated here.

In other embodiments, the first device may create a request interface proxy object for the Radio Interface and switch the Radio Interface to a remote access mode. When the first device itself has cellular communication capabilities, that is, the first device has a modem, the Radio Interface may be switched to a remote access mode to implement processing of the cellular communication request by the modem of a remote device (i.e., the second device) instead of using a local modem to process the cellular communication request. In some embodiments, the request interface proxy object created by the first device may implement asynchronous call processing.

In some embodiments, in addition to executing step S907, the telephone manager in the application framework layer of the first device needs to be modified so that after receiving a request for a cellular communication service, the telephone manager does not call the original HIDL interface, but calls the proxy object of the request interface created in step S907.

In some embodiments, step S907 may be triggered by step S905 or step S906, that is, after the connection between the first device and the second device is established, step S907 is triggered, or the distributed cellular communication module of the first device automatically triggers step S907 after sending a cellular communication capability sharing request. In other embodiments, it may also be triggered by step S909, that is, after receiving the cellular communication capability sharing success information and ensuring that the second device successfully responds to the cellular communication capability sharing request, step S907 is triggered.

In the above-mentioned usage scenario of the cellular communication function, the same specific application needs to be configured on the first device and the second device to forward the request of the first device to the device with cellular communication capability (i.e., the second device) from the application level, and then the second device uses the cellular communication capability to process the application level request using the local modem to complete the transfer of the cellular communication function supported by the specific application. Therefore, each device must install the same specific application to complete the transfer of the cellular communication function, and a specific application only supports the transfer of one cellular communication function. Some basic cellular communication functions cannot even be transferred by configuring a specific application.

In the embodiment of the present application, since a distributed cellular communication module is newly added to the first device, the distributed cellular communication module of the first device creates a proxy object of the request interface to realize that the request for the cellular communication service received by the phone manager of the first device is no longer sent to the Modem through the HIDL interface, but forwards the request for the cellular communication service to the distributed cellular communication module of the second device through the proxy object of the request interface, and then the distributed cellular communication module of the second device can then send the request for the cellular communication service to the local Modem for processing, helping the first device to use the cellular communication capability. Wherein, the Modem can be the modem processor 5021 in Figure 5. As shown in Figure 5, the distributed cellular communication module of the first device creates a proxy object of the request interface to establish a connection between the first device and the second device at the application framework layer, and then can implement the execution of step S5014 in Figure 5, that is, forwarding the request for the cellular communication service to the second device, and further, the second device can execute step S5015 to send the request for the cellular communication service to the modem processor 5021. For another example, the Modem can also be the Modem in the mobile phone 11 in Figure 1. As shown in Figure 1, when the first device is a smart screen 16 and the second device is a mobile phone 11, the smart screen 16 forwards the request for cellular communication service to the mobile phone 11 by creating a proxy object of the request interface. Then the mobile phone 11 can send the request for cellular communication service to the modem of the mobile phone 11 for processing, thereby helping the smart screen 16 to use the cellular communication capability of the mobile phone 11.

It can be seen from this that in the embodiment of the present application, the request for the cellular communication service of the first device does not need to go through the application layer of the second device, and therefore does not rely on the same specific application that needs to be installed in the second device and the first device. In addition, after the first device creates a proxy object for the request interface, the request for the cellular communication service of the first device can be forwarded to the Modem of the second device for processing through the distributed cellular communication module of the first device. Therefore, the first device can use all cellular communication capabilities of the second device, unlike the prior art where only the cellular communication functions supported by the applications installed on each device can be used.

It should be noted that the type and specific method of the interface created by the first device in step S907 are not limited. In addition to creating a proxy object for the request interface, the first device can also create proxy objects for other types of interfaces.

S908: The second device responds to the cellular communication capability sharing request and creates a proxy object of the response interface and a proxy object of the notification interface.

Among them, the proxy object of the response interface is used to forward the response data corresponding to the request for the cellular communication service to the distributed cellular communication module of the first device. The proxy object of the notification interface is used to forward the notification of the cellular communication service reported by the local modem to the distributed cellular communication module of the first device. In some embodiments, when the modem detects that there is a cellular communication service, such as detecting a text message notification, it will notify the distributed cellular communication module of the second device through the proxy object of the notification interface, and the proxy object of the notification interface will send the notification of the cellular communication service to the distributed cellular communication module of the first device. Among them, the format, quantity and content of the notification of the cellular communication service can be specifically referred to the provisions of operating systems such as Android or IOS, and the embodiments of this application are not limited here. The specific method for the modem to report the notification of the cellular communication service can also refer to the provisions of operating systems such as Android or IOS, and the embodiments of this application are not limited here.

The response data corresponding to the request for the cellular communication service is data used to respond to the request for the cellular communication service, and corresponds to the request for the cellular communication service. In some embodiments, the notification of the cellular communication service can be, for example, a text message received by the SIM card of the second device, a call to the SIM card of the second device, etc. The response data corresponding to the request for the cellular communication service and the cellular communication service can both come from the modem and be reported and sent by the modem.

In some embodiments, the proxy object of the response interface and the proxy object of the notification interface may be created by the distributed cellular communication module of the second device. The proxy object of the response interface and the proxy object of the notification interface may be created inside the distributed cellular communication module of the second device.

Specifically, the process of executing step S908 may be to create a proxy object of the response interface and a proxy object of the notification interface based on the design pattern of the proxy mode. Among them, the proxy object of the response interface is the proxy object of the second type of HIDL interface in the above-mentioned scheme of the electronic device with cellular communication capability using the local cellular communication function. The created proxy object of the response interface has the functions of the second type of HIDL interface mentioned above, and extends other functions. By extending additional functional operations in the proxy object of the response interface, it can be realized that the proxy object of the response interface can forward the response data corresponding to the request of the cellular communication service to the distributed cellular communication module of the first device. The proxy object of the notification interface is the proxy object of the third type of HIDL interface in the scheme of the electronic device with cellular communication capability using the local cellular communication function mentioned above. The created proxy object of the notification interface has the functions of the third type of HIDL interface mentioned above, and extends other functions. By extending additional functional operations in the proxy object of the notification interface, it can be realized that the proxy object of the notification interface can forward the notification of the cellular communication service reported by the local Modem to the distributed cellular communication module of the first device.

It should be noted that the specific principle of the proxy mode can be found in the relevant part of the proxy mode mentioned above, which will not be repeated here. The detailed introduction of the scheme for the electronic device with cellular communication capability to use the local cellular communication function can be found in the relevant part of the scheme for the electronic device with cellular communication capability to use the local cellular communication function mentioned above, which will not be repeated here.

The response data corresponding to the request for cellular communication service was originally sent from the modem to the telephone manager of the local application framework layer through the second type of HIDL interface mentioned above. However, after the proxy object of the response interface is created, the response data corresponding to the request for cellular communication service that the modem needs to send will be sent to the proxy object of the response interface, and will not be directly returned to the local telephone manager.

The notification of cellular communication service is also required to be actively reported from the modem to the telephone manager of the local application framework layer through the third-class HIDL interface. However, after the proxy object of the notification interface is created, the notification of cellular communication service that the modem needs to report will be sent to the proxy object of the notification interface, and will not be sent to the local telephone manager. Through the proxy object of the response interface and the proxy object of the notification interface, the response data corresponding to the request for cellular communication service notified by the modem and the notification of cellular communication service can all be sent to the distributed cellular communication module of the second device, and then distributed by the distributed cellular communication module of the second device.

From the introduction of the above-mentioned scheme of an electronic device with cellular communication capability using the local cellular communication function, it can be seen that in the above scheme, the response data corresponding to the request for cellular communication service and the cellular communication service are sent by the local modem to the telephone manager in the local application framework layer, and then the telephone manager directly sends them to the application corresponding to the local cellular communication service request, that is, the response data corresponding to the request for cellular communication service and the cellular communication service can only be sent locally on the device with cellular communication capability. In the embodiment of the present application, in order to enable the first device to have the cellular communication capability of the second device, that is, to be able to receive response data and cellular communication services corresponding to requests for cellular communication services, a distributed cellular communication module is added to the second device, and then the distributed cellular communication module of the second device creates a proxy object of the response interface and a proxy object of the notification interface, so that the response data corresponding to the request for cellular communication services and the notification of cellular communication services processed by the modem of the second device are no longer sent from the modem to the telephone manager, but are sent by the modem to the distributed cellular communication module of the second device. The distributed cellular communication module of the second device will receive the response data corresponding to the request for cellular communication services through the created proxy object of the response interface, receive the cellular communication services through the proxy object of the notification interface, and then send the received notification of cellular communication services and the response data corresponding to the request for cellular communication services to the distributed cellular communication module of the first device.

Therefore, after the first device forwards the request for the cellular communication service to the second device, the distributed cellular communication module of the second device can realize that the first device receives the response data corresponding to the request for the cellular communication service through the proxy object of the created response interface, so that the first device can successfully use the cellular communication capability of the second device. And the second device can also actively report the notification of the cellular communication service to the first device through the proxy object of the notification interface.

In some embodiments, the proxy object of the response interface and the proxy object of the notification interface may be created only for the first device, that is, the proxy object of the notification interface and the proxy object of the notification interface are only used to forward to the distributed cellular communication module of the first device, and are not used to forward to the distributed cellular communication modules of other devices. If other devices send requests to share cellular communication capabilities, it is necessary to create proxy objects of the notification interface and the proxy objects of the notification interface that are exclusive to the other devices for processing. In other embodiments, the proxy object of the response interface and the proxy object of the notification interface may be created for all devices that want to use the cellular communication capabilities shared by the second device, that is, the proxy object of the notification interface and the proxy object of the notification interface can be forwarded to the distributed cellular communication modules of all devices that have issued requests to share cellular communication capabilities, and are not just for the first device.

In some embodiments, after the distributed cellular communication module of the second device receives the cellular communication capability sharing request and responds to the cellular communication capability sharing request, it may directly create a proxy object of the response interface and a proxy object of the notification interface for the first device, or it may perform a series of authentication operations on the cellular communication capability sharing request and then create the proxy object of the response interface and the proxy object of the notification interface after the authentication passes. If the authentication fails, no creation is performed.

In the existing solution, the cross-device use of a certain cellular communication capability can only be achieved by developing applications separately, and other applications cannot use the cellular communication capability. In this solution, the first device creates a proxy object for the request interface, and the second device creates a proxy object for the response interface and a proxy object for the notification interface, so that the first device can call the cellular function of the second device. The first device is equivalent to simulating a cellular module locally, so that the first device can have complete cellular communication capabilities.

It should be noted that in addition to steps S907 and S908 that allow the first device to use all cellular communication capabilities of the second device, other methods may also be used to allow the first device to use all cellular communication capabilities of the second device. Steps S907 and S908 are merely one implementation method for allowing the first device and the second device to have the condition for the first device to use all cellular communication capabilities of the second device.

It should also be noted that the type and method of the interface created by the second device in step S908 are not limited in the embodiments of the present application, and the second device may also create proxy objects of other types of interfaces. In some embodiments, if the second device only has a response interface but not a notification interface, it may also only create a proxy object of the response interface when executing step S908.

S909: The second device sends cellular communication capability sharing success information to the first device.

The cellular communication capability sharing success information is used to indicate that the second device has accepted the cellular communication capability sharing request sent by the first device in step S906 and is willing to share the cellular communication capability of the second device with the first device, so that the first device can obtain all sharable cellular communication capabilities of the second device.

In a possible implementation, the cellular communication capability sharing information may include information on all shared cellular communication capabilities of the second device. When the first device receives the cellular communication capability sharing success information, it can obtain all shared cellular communication capabilities of the second device.

Through step S901 to step S909, the first device completes the configuration of using the modem of the second device, and the second device completes the configuration of providing the modem of the second device to the first device, that is, through step S901 to step S909, the first device completes the preparation work before using the cellular communication capability of the second device.

In some embodiments, the distributed cellular communication module of the second device may send the cellular communication capability sharing success information to the distributed cellular communication module of the first device.

It should be noted that steps S901 to S909 are only one implementation method for implementing the preparation work of the first device before using the cellular communication capability of the second device. In other embodiments, the preparation work of the first device before using the cellular communication capability of the second device may also be completed by other methods.

S910: The first device performs scene recognition, and determines whether to enable cellular communication capability according to the scene.

In an embodiment of the present application, the first device may store a correspondence between a scene and a cellular communication function. The correspondence between the scene and the cellular communication function may be preset in the first device, or the correspondence between the scene and the cellular communication function may be obtained by the first device through self-learning based on historical data of the user using the first device. The scene may be obtained by the first device through scene recognition based on the application currently used by the user, the content displayed by the first device, and/or the state of the user (or the first device) detected by the first device based on an artificial intelligence (AI) recognition module.

Exemplarily, the first device performs scene recognition and can determine whether the cellular communication function can be turned on in the scene based on the correspondence between the scene and the cellular communication function. For example, when the first device recognizes the current scene and finds the cellular communication function corresponding to the scene from the correspondence between the scene and the cellular communication function, it can determine the cellular communication function that can be turned on; or, when the first device does not recognize the current scene, or recognizes the current scene and does not find the cellular communication function corresponding to the current scene from the correspondence between the scene and the cellular communication function, it can be determined that there is no cellular communication function that needs to be turned on.

Exemplarily, the scene may include one or more of the following, for example: a work scene, a game scene, a power saving scene, a sleep scene, or a boarding scene. It is understandable that when the first device is in different scenes, different cellular communication functions can be adapted. Exemplarily, Table 1 is a schematic table of the correspondence between a scene and a cellular communication function provided in an embodiment of the present application.

Table 1 is a schematic diagram of the correspondence between a scenario and a cellular communication function provided in an embodiment of the present application

It is understandable that the embodiments of the present application do not specifically limit the types and numbers of scenarios, and the types and numbers of cellular communication functions corresponding to the scenarios.

Exemplarily, Figure 10 is another scenario diagram provided in an embodiment of the present application. As shown in Figure 10, the scenario may include a mobile phone 1001 and a tablet 1002. Among them, the tablet 1002 can be understood as the first device described in the embodiment of the present application, and the mobile phone 1001 can be understood as the second device described in the embodiment of the present application.

Exemplarily, as shown in FIG10 , when the mobile phone 1001 has shared the cellular communication capability with the tablet 1002 based on the steps shown in S901 - S909 , the user can use the tablet 1002 to realize functions such as playing games, sending and receiving text messages, and receiving calls.

As shown in FIG10 , when a user opens a game application in a tablet 1002, the tablet 1002 may display a game interface based on the data service Internet access function; or, when the tablet 1002 receives a call based on the called call function, the tablet 1002 interface may also display a prompt message 1003, which is used to prompt the user that an incoming call is received. The prompt message 1003 may include the user name, phone number, answer control 1004, and hang up control 1005 of the incoming call. Further, when the user determines to answer the call during the game, the answer control 1004 may be triggered to answer the call; or, when the user determines to hang up the call during the game, the hang up control 1005 may be triggered to hang up the call.

It is understandable that in different scenarios, users may have different requirements for cellular communication functions. For example, when users play games in their free time at work during the day, they need to pay attention to phone calls and text messages even while playing games to avoid missing important information at work; or, when users play games after get off work, they do not need to pay attention to or even need to block phone calls and text messages to avoid the impact of phone calls and text messages on game operations.

In a possible implementation, as shown in FIG5 , the correspondence between the scenario and the cellular communication function can be set in the configuration file of the distributed cellular communication module 5011; the AI recognition module can be set in the application framework layer. It is understandable that the correspondence between the scenario and the cellular communication function and the AI recognition module can be set in other locations according to the actual scenario, which is not limited in the embodiments of the present application.

In the embodiment of the present application, the first device can determine the cellular communication capabilities that can be enabled in different scenarios based on the following two methods. In method 1, the first device can automatically identify the scenario and determine the cellular communication function that can be enabled in the scenario based on a preset correspondence relationship or a preset relationship obtained by self-learning based on the historical data of the user using the first device; in method 2, the first device can determine the cellular communication function that can be enabled in different scenarios based on the manual settings of the user.

Method 1: The first device can automatically identify the scene and determine the cellular communication function that can be enabled in the scene based on a preset correspondence relationship or a preset relationship obtained through self-learning of historical data of the user using the first device.

Among them, the first device can obtain historical data of the user's use of the cellular communication function in different scenarios for a period of time, such as 7 days, and obtain the correspondence between the scenario and the cellular communication function by further learning the historical data. Exemplarily, when the first device records that the user often answers calls and checks text messages when playing games in the time period of 9:00 am to 6:00 pm, and records that the user often hangs up the phone and cancels the text message when playing games in the time period of 8:00 pm to 11:30 pm, then the first device can establish a correspondence between the work scenario (such as game application) and the text message sending and receiving function, the called call function, and the data service Internet access function in the time period of 9:00 am to 6:00 pm based on the above historical operations of the user, and establish a correspondence between the game scenario (such as game application) and the data service Internet access function in the time period of 8:00 pm to 11:30 pm. It can be understood that the correspondence between the scenario and the cellular communication function obtained by the first device based on the self-learning of the user's historical data can be more in line with the user's usage habits.

In one implementation, the first device may store a correspondence between scenes and cellular communication functions. For example, the first device may store a correspondence between game scenes and functions such as data service Internet access functions.

In an embodiment of the present application, as shown in the scenario corresponding to Figure 10, when the second device (such as mobile phone 1001) has shared cellular communication capabilities with the first device (such as tablet 1002), when the first device (such as tablet 1002) detects the user's operation of opening a game application, the first device (such as tablet 1002) can determine, based on the scenario to which the game application belongs, that the data service Internet access function can be enabled in the game scenario.

In a possible implementation, as shown in FIG5 , the correspondence between the scene and the cellular communication function may be stored in the distributed cellular communication module 5011 of the first device, and a listener may be provided in the distributed cellular communication module 5011. The listener is used to monitor the target object (e.g., target application or target event), and when the target object triggers a specified event, the listener in the distributed cellular communication module 5011 may receive a notification.

Exemplarily, when a user opens a game application, the distributed cellular communication module 5011 of the first device can monitor the triggering of the game application based on the listener, and identify that the game application satisfies the application of the game scenario; further, the distributed cellular communication module 5011 can determine, based on the corresponding relationship, that the data service Internet access function can be enabled in the game scenario.

In another implementation, the first device may store the correspondence between the scene and the cellular communication function, and the first device may also be provided with an AI recognition module.

In an embodiment of the present application, when the second device has shared cellular communication capabilities with the first device, when the first device determines based on the received ticket purchase information that the user has ordered a flight ticket and is close to the departure time indicated in the ticket purchase information, and determines based on GPS positioning that the user is at the airport, the first device can identify based on the AI recognition module that the current user may be boarding or waiting for take-off, thereby satisfying the boarding scenario; further, the first device can determine that all cellular communication functions can be turned off in the boarding scenario.

In a possible implementation, as shown in FIG. 5 , the correspondence between the scenarios and the cellular communication functions may be stored in the distributed cellular communication module 5011 of the first device; and an AI recognition module may be provided in the application framework layer of the first device.

Exemplarily, as shown in FIG5 , the AI recognition module is set in the application framework layer as an example for illustration. The GPS in the first device can send the user's location message to the AI recognition module in the application framework layer in real time; the AI recognition module can identify the current scene based on the text message content indicated in the short message application of the first device, such as ticket purchase information, and the user's location message sent by the GPS, and determine that the boarding scene is met in the current scene; send the information containing the boarding scene to the distributed cellular communication module 5011; further, the distributed cellular communication module 5011 can determine that there is no cellular communication function that needs to be turned on in the boarding scene based on the corresponding relationship.

In another implementation, the first device may store the correspondence between the scene and the cellular communication function, and the first device may also be provided with an AI recognition module, wherein the AI recognition module not only realizes scene recognition, but also can intelligently determine the cellular communication function that can be enabled in the scene based on the scene.

In an embodiment of the present application, when a second device, such as a mobile phone, has shared cellular communication capabilities with multiple first devices, such as a smart watch and a tablet, when the tablet detects based on the camera that the user is currently looking at the tablet, the tablet can determine based on the AI recognition module that the current user is using the device, and intelligently determine that all cellular communication functions can be turned on in this scenario. Moreover, when the smart watch detects based on the camera that the user is not looking at the smart watch, the smart watch can determine based on the AI recognition module that the current user is not using the device, and intelligently determine that all cellular communication functions can be turned off in this scenario.

Exemplarily, as shown in FIG5 , the AI recognition module is set in the application framework layer as an example for illustration. The camera in the hardware layer of the first device can send the captured image to the AI recognition module in the application framework layer via the kernel layer and the system library; the AI recognition module can perform image recognition on the image. Further, when the AI recognition module in the tablet determines that the user is using the tablet based on the image and the preset face information (or human shape information, or eyeball information, etc.), it can determine to turn on all cellular communication functions of the tablet, and send a message containing turning on all cellular communication functions to the distributed cellular communication module 5011, and the distributed cellular communication module 5011 turns on all cellular communication functions; or, when the AI recognition module in the smart watch determines that the user is not using the smart watch based on the image and the preset face information (or human shape information, or eyeball information, etc.), it can determine to turn off all cellular communication functions of the smart watch, and send a message containing turning off all cellular communication functions to the distributed cellular communication module 5011, and the distributed cellular communication module 5011 turns off all cellular communication functions.

It is understandable that the AI recognition module can be combined with the sensors of the device to intelligently identify the status of the device or the user, etc., to obtain more accurate scene information, or to obtain more accurate cellular communication functions that can be turned on or off.

In a possible implementation, in addition to the above-mentioned AI recognition module, the first device may also perform scene recognition in combination with other intelligent recognition modules provided in the device, which is not limited in the embodiments of the present application.

It is understandable that the above description of scene recognition and cellular communication functions corresponding to different scenes is only an example and does not constitute a further limitation on the embodiments of the present application.

In a possible implementation, when the second device is a dual-card device, for example, including SIM card 1 and SIM card 2, the dual cards can also provide cellular communication functions for different devices respectively. Exemplarily, when a second device with dual cards, such as a mobile phone, has shared cellular communication capabilities with multiple first devices, such as a tablet and a smart watch, the tablet can implement functions such as sending and receiving text messages based on SIM card 1 in the mobile phone, and the smart watch can implement functions such as making and receiving calls based on SIM card 2 in the mobile phone.

In a possible implementation, the first device may be a dual-card device, for example, including SIM card 1 and SIM card 2. Exemplarily, when the second device has shared the cellular communication capability with the first device having dual cards, SIM card 1 of the first device may implement the cellular communication function based on a local modem, and SIM card 2 of the first device may implement the cellular communication function based on the modem of the second device.

It can be understood that in the embodiments of the present application, there is no specific limitation on the number of SIM cards included in the first device and the number of SIM cards included in the second device.

Method 2: The first device may also determine the cellular communication functions that can be enabled in different scenarios based on the manual settings of the user.

In an embodiment of the present application, the first device can determine the cellular communication capabilities that can be enabled in different scenarios based on the user's settings for cellular communication functions in different scenarios in the settings application, or the settings for the cellular communication functions that can be enabled in any application.

In one implementation, the first device can enable the user to set the cellular communication function in different scenarios in the setting application. For example, FIG11 is a schematic diagram of an interface for setting cellular communication capabilities provided in an embodiment of the present application. In the embodiment corresponding to FIG11, the first device is taken as an example of a mobile phone, and the example does not constitute a limitation on the embodiment of the present application.

When the mobile phone receives an operation from the user to open the cellular communication sharing setting function in the setting application, the mobile phone can display an interface as shown in a in Figure 11, which may include controls for turning on the sharing of the cellular communication function, available cellular communication devices such as device 1 and device 2 searched when the cellular communication function sharing is turned on, and advanced setting controls for making other settings for the cellular communication sharing settings, etc.

When the mobile phone receives the user's operation of triggering the advanced setting control in the interface shown in a of FIG. 11, the mobile phone may display the interface shown in b of FIG. 11. The interface shown in b of FIG. 11 may include multiple scenes, such as work scene, game scene, power saving scene, sleep scene, and boarding scene. In the power saving scene, when the power of the device is less than 30%, the device may automatically enter the power saving scene.

When the mobile phone receives the user's operation of triggering the control corresponding to the work scene in the interface shown in b of Figure 11, the mobile phone can display the interface shown in c of Figure 11. As shown in the interface in c of Figure 11, the interface may include controls for opening the work scene, and a variety of cellular communication functions that can be set when the work scene is opened. Among them, the applicable time of the work scene can be within the time period of 9:00 am to 6:00 pm, and the work scene can correspond to the opening state of the basic public function, the opening state of the calling call function, the opening state of the called call function, the opening state of the SMS sending and receiving function, the opening state of the data service Internet access function, and the opening state of the SIM card reading function, etc.

It is understandable that the user can flexibly set the cellular communication functions in the game scene, power saving scene, sleep scene, and boarding scene based on the embodiment corresponding to Figure 11. For example, the game scene can correspond to the activation state of the basic public function and the activation state of the data service Internet access function, etc.; the power saving scene can correspond to the activation state of the basic public function, the activation state of the calling call function, the activation state of the called call function, and the activation state of the SMS sending and receiving function, etc.; the sleep scene can correspond to the activation state of the basic public function; the boarding scene can correspond to the deactivation state of all cellular communication functions, etc.

In a possible implementation, the first device may also support sharing of different cellular communication functions in multiple scenarios such as video scenarios or sports scenarios. For example, the video scenario may be understood as a scenario in which a user watches a video, such as a user watching a movie or viewing a short video, and the video scenario may correspond to the activation state of the basic public function, the activation state of the data service Internet access function, the activation state of the calling call function, the activation state of the called call function, and the activation state of the SMS sending and receiving function. The sports scenario may be understood as a scenario in which a user is exercising, and the sports scenario may correspond to the activation state of the basic public function, the activation state of the data service Internet access function, the activation state of the calling call function, and the activation state of the called call function.

In a possible implementation, the first device may support automatically turning on the corresponding cellular communication function, or the first device may also support automatically turning on the cellular communication function corresponding to the above scenario within a specific time period. For example, the first device may support the user to set the automatic start time of the scene in any of the above scenarios. For example, the user may set the start time of the sleep scene to 11:30 pm to 7:00 am. It can be understood that during the time period from 11:30 pm to 7:00 am, the first device will automatically enter the sleep mode, automatically turn on the basic public functions corresponding to the sleep mode, and turn off other cellular communication functions not related to the sleep mode.

In a possible implementation, the first device may support the functions of adding and deleting the above-mentioned modes, as well as automatic recommendation of modes. For example, the first device may support users to delete modes that are not frequently used, and add cellular communication functions that are more relevant to the user's usage habits. The first device may also automatically identify the scenarios in which users use cellular communication functions and related cellular communication functions, and recommend the learned scenarios and the cellular communication functions that users frequently use in the scenarios to the user in the cellular communication sharing settings interface (such as the interface shown in b in Figure 11).

In a possible implementation, when the second device has shared the cellular communication capability with multiple first devices, any first device may also support the scene and device sharing of the cellular communication capability in the cellular communication sharing setting. For example, when the multiple first devices include devices such as a tablet and a smart watch, the tablet can send the scene and cellular communication function set in the device to the smart watch through device sharing.

In a possible implementation, the first device may also add a control for opening the cellular communication sharing setting interface in the negative one screen or the pull-down notification interface, so that the user can trigger the control for opening the cellular communication sharing setting interface in the negative one screen or the pull-down notification interface, and conveniently enter the cellular communication sharing setting interface (for example, the interface shown in a in Figure 11, or the interface shown in b in Figure 11).

In a possible implementation, an icon may also be provided in the negative first screen or the pull-down notification interface of the first device, and the icon is used to identify the currently applicable scenario. Further, the user can change the current scenario by triggering the icon, thereby changing the cellular communication function corresponding to the current scenario; or it can be understood that the user can implement a quick switch of the mode (and the cellular communication function corresponding to the mode) in the negative first screen or the pull-down notification interface of the first device without entering the cellular communication sharing setting interface.

In another implementation, the first device can enable the user to set the cellular capabilities for different applications in the application. For example, FIG12 is a schematic diagram of another interface for setting cellular communication capabilities provided in an embodiment of the present application. In the embodiment corresponding to FIG12, the first device is taken as an example of a mobile phone, and the example does not constitute a limitation on the embodiment of the present application.

Exemplarily, setting the cellular communication capability in the call application of the first device is used as an example for explanation. When the mobile phone receives the user's operation to open the setting function in the call application, the mobile phone can display an interface as shown in a of FIG. 12 , which can display functions such as unfamiliar number recognition and call record merging corresponding to common functions, and functions such as call rejection text messages and speed dialing corresponding to other functions, and the interface can also include advanced setting controls.

When the mobile phone receives the user's operation of triggering the advanced setting control in the interface shown in a of FIG12, the mobile phone may display the interface shown in b of FIG12. As shown in the interface in b of FIG12, the interface may display a control for enabling the function of ending a call by pressing the power button, a cellular communication sharing setting control, and other contents.

When the mobile phone receives the user's operation of triggering the cellular communication sharing setting control in the interface shown in b of Figure 12, the mobile phone can display the interface shown in c of Figure 12. As shown in the interface in c of Figure 12, the interface can display a variety of cellular communication functions that can be set in the call application. For example, in the call application, it can correspond to the activation state of the basic public function, the activation state of the calling call function, the activation state of the called call function, the activation state of the SMS sending and receiving function, the activation state of the data service Internet access function, and the activation state of the SIM card reading function.

It is understandable that the method for setting the supported cellular communication functions in other applications can refer to the embodiment corresponding to FIG. 12 , which will not be described in detail here.

In a possible implementation, the user may also set the cellular communication function applicable to different applications in the settings application; or, the user may also set the cellular communication function corresponding to the scenarios to which different applications belong in other applications, which is not specifically limited in the embodiments of the present application.

In possible implementations, the first device may periodically perform scene recognition, or the first device may perform scene recognition after establishing a connection with the second device in the step shown in S905, or the first device may perform scene recognition after device discovery in the step shown in S902. It is understandable that the step shown in S810 may be performed at any step between S902-S909, and this is not limited in the embodiments of the present application. Exemplarily, when the first device performs scene recognition in the step shown in S902 and determines that the cellular communication function does not need to be enabled in this scenario, a prompt message may be sent to the second device, and the prompt message is used to prompt that the first device currently does not support enabling the cellular communication function.

S911. The first device obtains an interface corresponding to the cellular communication capability, and adds the interface corresponding to the cellular communication capability to a whitelist.

In the embodiment of the present application, the whitelist is used to store interfaces that can support the invocation of cellular communication capabilities. In a possible implementation, as shown in FIG5 , the distributed cellular communication module 5011 of the first device and the distributed cellular communication module 5022 of the second device may store a configuration file, in which the corresponding relationship between scenario information, cellular communication functions, and interfaces is preset.

Exemplarily, the first device can determine the cellular communication function that can be turned on based on the scene recognition in the step shown in S910, and based on the correspondence between the scene information, cellular communication function, and interface preset in the configuration file of the distributed cellular communication module, determine the interface corresponding to the turned-on cellular communication function, and add the interface corresponding to the turned-on cellular communication function to the whitelist. The following Table 2 is a schematic table of the correspondence between a cellular communication function and an interface provided in an embodiment of the present application.

Table 2 Schematic diagram of the correspondence between cellular communication functions and interfaces

It is understandable that the embodiments of the present application do not specifically limit the number of cellular communication functions and the number of interfaces corresponding to the cellular communication functions.

In a possible implementation, as shown in FIG5 , the first device's distributed cellular communication module 5011 may also update the whitelist to the second device's distributed cellular communication module 5022. For example, the first device's distributed cellular communication module 5011 may send a message containing an interface in the whitelist to the second device's distributed cellular communication module 5022; the second device's distributed cellular communication module 5022 receives the message containing an interface in the whitelist and returns a response message to the first device's distributed cellular communication module 5011. At this time, the first device and the second device may implement capability negotiation, so that the second device may obtain the whitelist determined by the first device based on the scenario.

S912: When the first device receives cellular communication service data, it determines whether the interface corresponding to the cellular communication service data satisfies the whitelist.

In an embodiment of the present application, the cellular communication service data may be a request for a cellular communication service (the request for the cellular communication service may correspond to a request class interface), or the cellular communication service data may also be a notification of a cellular communication service or a response message of a cellular communication service (the notification of the cellular communication service and the response message of the cellular communication service may both correspond to an active reporting class interface). Among them, the request class interface may be the first class HIDL interface described in the above embodiment; the active reporting class interface may be a second class HIDL interface or a third class HIDL interface.

Exemplarily, the cellular communication service data is a request for a cellular communication service. As shown in FIG5 , when the short message application in the application layer of the first device triggers the request for a cellular communication service, the short message application can send the request for the cellular communication service to the distributed cellular communication module 5011 of the first device via the phone manager 5012 in the application framework layer; then, the distributed cellular communication module 5011 of the first device executes the step shown in S912 to determine whether the interface corresponding to the request for the cellular communication service satisfies the whitelist.

Exemplarily, the cellular communication service data is taken as an example for explanation, as shown in Figure 5, when the distributed cellular communication module 5011 of the first device receives the notification of the cellular communication service (or the response message of the cellular communication service) sent by the distributed cellular communication module 5022 of the second device, the distributed cellular communication module 5011 of the first device executes the steps shown in S912 to determine whether the interface corresponding to the notification of the cellular communication service (or the response message of the cellular communication service) satisfies the whitelist.

In a possible implementation, as shown in Figure 5, when the distributed cellular communication module 5011 of the first device updates the whitelist to the distributed cellular communication module 5022 of the second device based on the step shown in S912, when the distributed cellular communication module 5022 of the second device receives the notification of the cellular communication service (or the response message of the cellular communication service) transmitted to the distributed cellular communication module 5022 via the RIL module in the system library by the Modem 5021 of the second device, the distributed cellular communication module 5022 of the second device can determine whether the interface corresponding to the notification of the cellular communication service (or the response message of the cellular communication service) satisfies the whitelist.

S913: The first device determines whether to forward the cellular communication service data according to the whitelist.

Exemplarily, the cellular communication service data is a request for a cellular communication service. As shown in FIG5 , when the distributed cellular communication module 5011 of the first device determines that the interface corresponding to the request for the cellular communication service satisfies the whitelist, the request for the cellular communication service can be forwarded to the distributed cellular communication module 5022 of the second device; or, when the distributed cellular communication module 5011 of the first device determines that the interface corresponding to the request for the cellular communication service does not satisfy the whitelist, it can return not support to the upper layer.

In a possible implementation, when the distributed cellular communication module 5011 of the first device determines that the interface corresponding to the request for the cellular communication service does not satisfy the whitelist, the distributed cellular communication module 5011 of the first device can send a message containing "notsupport" to the short message application in the application layer via the phone manager 5012 in the application framework layer. At this time, a prompt message can be displayed in the interface of the short message application, and the prompt message is used to indicate that the first device currently does not support the cellular communication function corresponding to the request to use the cellular communication service.

Exemplarily, the cellular communication service data is a notification of a cellular communication service (or a response message of a cellular communication service) as an example for explanation. As shown in FIG5 , when the distributed cellular communication module 5011 of the first device determines that the interface corresponding to the notification of the cellular communication service (or the response message of the cellular communication service) sent by the distributed cellular communication module 5022 of the second device satisfies the whitelist, the notification of the cellular communication service (or the response message of the cellular communication service) can be sent to the short message application in the application layer via the phone manager 5012 in the application framework layer; or, when the distributed cellular communication module 5011 of the first device determines that the interface corresponding to the notification of the cellular communication service (or the response message of the cellular communication service) sent by the distributed cellular communication module 5022 of the second device does not satisfy the whitelist, the notification of the cellular communication service (or the response message of the cellular communication service) can be discarded.

In a possible implementation, as shown in FIG5 , when the distributed cellular communication module 5011 of the first device updates the whitelist to the distributed cellular communication module 5022 of the second device based on the step shown in S912, when the distributed cellular communication module 5022 of the second device receives, the Modem 5021 of the second device transmits the notification of the cellular communication service (or the response message of the cellular communication service) to the distributed cellular communication module 5022 via the RIL module in the system library; further, when the distributed cellular communication module 5022 of the second device can determine that the interface corresponding to the notification of the cellular communication service meets the whitelist, the distributed cellular communication module 5022 of the second device can send the notification of the cellular communication service (or the response message of the cellular communication service) to the distributed cellular communication module 5011 of the first device; or, when the distributed cellular communication module 5022 of the second device determines that the interface corresponding to the notification of the cellular communication service (or the response message of the cellular communication service) does not meet the whitelist, the distributed cellular communication module 5022 of the second device can discard the notification of the cellular communication service (or the response message of the cellular communication service).

Based on this, the first device can realize flexible control of cellular communication functions based on business scenarios, such as matching appropriate cellular communication capabilities in different scenarios, enhancing the intelligence of cellular communication functions, and thereby improving the user experience of cellular communication functions.

In a possible implementation, before S906, the first device may also first identify the service scenario and determine the cellular communication function applicable to the scenario, and then obtain the cellular communication function applicable to the scenario from the second device.

In an embodiment of the present application, before S906, the first device can perform scene recognition based on the steps shown in S910, and determine whether the cellular communication capability can be enabled according to the scene, and then execute the steps shown in S906, and the first device sends a cellular communication capability sharing request corresponding to the cellular communication capability that can be enabled to the second device.

Exemplarily, as shown in Figure 5, before S906, the distributed cellular communication module 5011 of the first device can determine the cellular communication capability that can be enabled in the scenario based on scenario recognition, and send the information containing the cellular communication capability to the distributed cellular communication module 5022 of the second device through a cellular communication capability sharing request.

In a possible implementation, the first device may also store the correspondence between the device information of the first device and the cellular communication function. Before S906, the first device may determine the cellular communication function required by the device based on the device information of the first device, and then execute the steps shown in S906, and the first device sends the information containing the cellular communication function to the second device through a cellular communication capability sharing request. The correspondence between the device information and the cellular communication function may be preset in the first device, or may be obtained by the first device through self-learning based on historical data of the user using the cellular communication function of the first device.

Exemplarily, as shown in Figure 5, before S906, the distributed cellular communication module 5011 of the first device can determine the cellular communication capability that can be enabled in the scenario based on the correspondence between the device information of the first device stored in the distributed cellular communication module (or other modules, etc.) and the cellular communication function, and send the information containing the cellular communication capability to the distributed cellular communication module 5022 of the second device through a cellular communication capability sharing request.
