The GNSS geographic fence monitoring dimension can be the latitude and longitude coordinates of the mobile phone. The monitoring area of the GNSS geo-fence can be a circular area with a certain geographic location coordinate point as the center and a certain length as the radius, or a polygonal area with multiple geographic location coordinate points as vertices and connected vertices.

The monitoring dimension of the Cell geo-fence may be the identification of the base station of the cell scanned by the mobile phone. The monitoring area of the Cell geo-fence may be the signal coverage of one or more cell base stations.

The monitoring dimension of the Wi-Fi geofence can be the Wi-Fi signal scanned by the mobile phone. The monitoring area of the Wi-Fi geo-fence can be covered by one or more Wi-Fi signals.

In one case, the electronic device matches the current latitude and longitude coordinates with the location information corresponding to the geographic location. After the matching is successful, the mobile phone can determine that the user enters the GNSS geofence corresponding to the geographic location. In another case, the electronic device matches the ID of the scanned cell (Cell) base station with the ID of the corresponding cell base station. After the matching is successful, the mobile phone can determine that the user enters the geographic fence of the cell corresponding to the geographic location. In another case, the electronic device matches the scanned Wi-Fi identifier with the corresponding Wi-Fi identifier. After the matching is successful, the mobile phone can determine that the user enters the Wi-Fi geofence corresponding to the geographic location.

It should be noted that, in this embodiment of the application, the geo-fence may be simply referred to as a fence.

In some examples of the present application, as shown in Figure 2, to realize the automatic switching of the electronic device NFC card (also called NFC virtual card, that is, the virtual card that the electronic device has turned on), requires at least a processor, such as a sensor hub (sensorhub), short-distance chips, and baseband processors (also called baseband chips) and other hardware support, applications that also need to use fences, such as NFC card package applications and applications in system services (such as GPS applications, Wi-Fi application) and other software. The software and hardware can be connected through the hardware connection layer.

FIG. 3 is a schematic diagram of a software structure of an electronic device 100 provided by an embodiment of the present application.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate through software interfaces. In some embodiments, the system is divided into six layers, which are application program layer, application program framework layer, runtime (Runtime) and system library, hardware abstraction layer and kernel layer from top to bottom.

The application layer can consist of a series of application packages.

As shown in FIG. 3 , the application program layer may include application programs (also referred to as applications) such as call, map, wallet, navigation, and the like.

The application framework layer provides an application programming interface (Application Programming Interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

As shown in Figure 3, the application framework layer can include phone manager, content provider, view system, window manager, location-based services (Location Based Services, LBS) Service manager, NFC Service manager, resource manager , notification manager, etc.

The phone manager is used to provide communication functions of the electronic device 100 . For example, the management of calling card status (including connecting, hanging up, etc.).

Content providers are used to store and retrieve data and make it accessible to applications. Said data may include calls made and received, browsing history and bookmarks, phone book, etc.

The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and so on. The view system can be used to build applications. A display interface can consist of one or more views. For example, a display interface including a text message notification icon may include a view for displaying text and a view for displaying pictures.

A window manager is used to manage window programs. The window manager can get the size of the display screen, determine whether there is a card status bar, lock the screen, capture the screen, etc.

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and so on.

The notification manager enables the application to display notification information in the card status bar, which can be used to convey notification-type messages, and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify the download completion, message reminder, etc. The notification manager can also be a notification that appears on the top card status bar of the system in the form of a chart or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog interface. For example, prompting text information in the card status bar, issuing a prompt sound, vibrating the electronic device, and flashing the indicator light, etc.

Runtime (Runtime) includes the core library and virtual machine. Runtime is responsible for the scheduling and management of the system.

The core library includes two parts: one part is the function function that the programming language (for example, java language) needs to call, and the other part is the core library of the system.

The application layer and the application framework layer run in virtual machines. The virtual machine executes programming files (for example, java files) of the application program layer and the application program framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

A system library can include multiple function modules. For example: NFC protocol stack, surface manager (SurfaceManager), media library (Media Libraries), 3D graphics processing library (eg: OpenGL ES), 2D graphics engine (eg: SGL), etc.

The NFC protocol stack supports NFC functions, for example, determining NFC radio frequency parameters, completing NFC card swiping, and so on.

Hardware Abstraction Layer (Hardware Abstraction Layer, HAL) is the interface layer between the kernel layer and the hardware layer. The hardware abstraction layer can include, LBS interface, NFC interface, Bluetooth and camera, etc.

The kernel layer is the layer between hardware and software. The kernel layer includes at least a universal asynchronous receiver/transmitter (UART), a two-wire serial bus (interintegrated circuit, I2C) and a serial peripheral interface (serial peripheral interface, SPI).

In the embodiment of the present application, RIL is sent to the communication request of the application program and may include two parts, rild and Vendor RIL. communication.

Based on the above-mentioned software and hardware architectures in FIG. 2 and FIG. 3 , software and hardware can be connected through a hardware connection layer. The electronic device can realize the method of NFC radio frequency parameter compatibility through the combination of software and hardware.

First, electronic devices can acquire geofences.

The following describes several methods for electronic devices to obtain geofences:

When the electronic device enters a certain fence or exits a certain fence, the LBS Service manager of the electronic device can monitor the fence event, and then the LBS Service manager can broadcast the fence event. The NFC Service Manager can monitor fence events. After the NFCService manager listens to the broadcast of the fence event, it can determine the first radio frequency parameter based on the current geofence, the activation card and the first mapping relationship. For details, refer to step S503. After the NFCService manager determines the first radio frequency parameter, it can send the first radio frequency parameter to the NFC driver at the kernel layer through the system library and the hardware abstraction layer, so that the electronic device can perform NFC communication through the first radio frequency parameter.

Wherein, the application layer may include a wallet application, and the wallet application of the electronic device may send instruction information to the NFCService manager, for example, a parameter addition instruction, a parameter deletion instruction, and a parameter update instruction. After the NFCService manager receives the instruction information, it may adjust the first mapping relationship based on the instruction information. For details, reference may be made to related descriptions in FIG. 9 , FIG. 10 and FIG. 11 . Afterwards, the NFCService manager can broadcast instruction information for adjusting the fence. After receiving the NFCService manager, the LBSService manager can adjust the acquired fence event based on the instruction information.

The following introduces the application scenarios of the NFC involved in the embodiment of the present application.

Exemplarily, FIG. 4 is a schematic flow diagram of a payment between an electronic device and a POS machine disclosed in an embodiment of the present application. As shown in FIG. 4, the electronic device can open the corresponding NFC card as shown in FIG. 1A or FIG. 1B , when the electronic device is close to the POS machine, the electronic device can send a payment request to the POS machine. After the POS machine receives the payment request from the electronic device, it can send a payment response to the electronic device. In this way, mutual payment can be completed between the electronic device and the POS machine. After the above payment process, the corresponding merchant of the POS machine can complete the settlement of the account bound to the user's NFC card. It should be noted that, the NFC communication process in FIG. 4 is only an example for illustration and does not constitute a limitation.

During the NFC communication between the POS machine and the electronic device, the NFC radio frequency parameters between the electronic device and the POS machine need to match each other. For example, the frequency band of the wireless signal of the payment request sent by the electronic device to the POS machine should be within the frequency band of the POS machine, and its transmission power should enable the POS machine to perform modulation and demodulation. However, an electronic device needs to perform NFC communication with multiple NFC card reader devices, and the radio frequency parameters of the multiple NFC card readers are not the same. In this way, the radio frequency parameters during NFC communication may not match, resulting in communication failure.

In a possible implementation manner, the electronic device may receive a radio frequency parameter configuration table from the server, and the radio frequency parameter configuration table may include various application codes, radio frequency parameters of the POS machine and the correspondence between the two. After the electronic device acquires the application code of the application, it can determine the radio frequency parameters of the POS machine based on the above correspondence. Thereafter, the electronic device can be configured according to the radio frequency parameters of the POS machine, so that the electronic device with NFC function can communicate with the POS based on the radio frequency parameters of the POS machine.

In the above implementation manner, due to the different performances of different POS machines, the required parameters are also different in the process of swiping the card by the electronic device through the NFC function. For example, the size of the antenna of different POS machines is different, and the frequency point of the signal of different NFC card readers has different degrees of deviation during communication; the performance of receiving sensitivity and transmitting and receiving power of POS machines is not the same. Therefore, when the NFC parameters of the electronic device do not match the POS parameters, the user needs to approach the POS machine several times before successfully swiping the card. Therefore, in this case, the success rate of the user's NFC parameter matching is low, and the user needs to try to swipe the card multiple times, the success rate of the first NFC communication is low, and the user's experience of using the NFC card swiping function is poor.

In view of the above problems, in the embodiment of the present application, before the user tries to swipe the card multiple times, the electronic device can switch the NFC parameters in advance according to the current geo-fence and the mapping relationship between the geo-fence, the card used and the radio frequency parameters. The NFC radio frequency parameters matched between the electronic device and the POS machine can improve the success rate of the user's card swiping, reduce the number of times the user swipes the card, and improve the user experience.

Please refer to FIG. 5. FIG. 5 is a schematic flowchart of a method for NFC radio frequency parameter compatibility provided by the embodiment of the present application. The method can be executed by the electronic device 100 shown in FIG. 3. The method can include but not limited to the following steps :

S501. The electronic device acquires a fence event.

The electronic device can receive fence events from GPS, cell communication events, and Wi-Fi through the LBS module, and the fence event can be at least one of GNSS geo-fence events, Cell geo-fence events, or Wi-Fi geo-fence events. The fence event is used to indicate the situation that the electronic device enters or exits a certain fence, that is, the fence event can be divided into a fence event entering the fence and a fence event exiting the fence. After the LBS module of the electronic device monitors the fence event, it can broadcast the fence event. Correspondingly, the NFC module of the electronic device can monitor the fence event.

When the electronic device detects that a fence event is received, the current fence may be determined based on the above fence event. FIG. 6 is a schematic diagram of an action route of a user passing through a geo-fence disclosed in an embodiment of the present application. As shown in FIG. 6 , user A travels forward along the route 01 , and when user A travels to point A, the electronic device used by user A can detect entering the first fence. When user A travels to point B, the electronic device used by the user can detect the exit from the first fence. That is, it can be understood that when the electronic device enters a certain fence, it can obtain the fence event of entering a certain fence; when it exits a certain fence, the electronic device can obtain the fence event of exiting a certain fence. That is, after the NFC module of the electronic device receives the fence event, it can determine whether it is currently in the fence based on the fence event, and if it is in the fence, which fence it is in. For example, after user A receives the fence event of entering the first fence at point A, he can determine that he is in the fence, and the fence he is in is the first fence. After receiving the fence event of exiting the first fence at point B, user A can determine that he is not in the fence.

It should be noted that the specific shape of the geo-fence is not necessarily circular, but may also be in other shapes, which is not limited. In actual situations, the detection of electronic devices entering and exiting the geofence is more complicated than the above-mentioned situation.

S502. The electronic device acquires an activation card.

The electronic device can obtain the activation card through the NFC module.

The following describes the specific method by which the electronic device determines the activation of the card:

In a possible situation, when the user can select the NFC card, the electronic device can determine to activate the card. Fig. 7 is a schematic diagram of a user interface disclosed in the embodiment of the present application. As shown in (A) in Figure 7, the electronic device can display a user interface 10, and the user interface 10 is an NFC card package interface used by the user, which can include three cards: a community access control card, a smart door lock card and a public transportation card . It should be understood that the types of cards and the number of cards included in the user interface 10 are just examples and not limited. When the user needs to use the smart door lock card, the user can click the control corresponding to the smart door lock card. The electronic device may display a user interface 20 as shown in (B) of FIG. 7 in response to the above-mentioned user operation. As shown in (B) of FIG. 7 , the user interface 20 can display the currently activated card, that is, the smart door lock card. Users can use the current smart door lock card to swipe the card.

In another possible situation, when the user brings the electronic device close to the NFC card reader, the electronic device does not need to display the user interface of the card package shown in (A) and (B) in Figure 7 ( The electronic device can determine the activation card without the operation of the user clicking to select the card), and the electronic device can also obtain the activation card.

Exemplarily, the electronic device may determine to activate the card based on the current geo-fence. After the electronic device obtains the fence event of entering the fence, it can determine the fence it is currently in based on the fence event, and can determine the card that the electronic device needs to activate based on the fence and the correspondence between the fence and the card. The determined card is activated. Thereafter, the electronic device can obtain the activation card.

Exemplarily, the electronic device may determine the type of the nearby NFC card reader based on the detected radio frequency information, and determine the activated virtual card based on the type of the NFC card reader. For example, when the NFC card reader is a POS machine on a bus, the electronic device can determine that the activation card is a public transportation card.

It should be understood that the above-mentioned method for an electronic device to obtain an activation card is only an exemplary description and does not constitute a limitation.

It should be noted that the order of step S501 and step S502 is not limited, and the fence event may be obtained first, and then the activation card may be obtained; or the card may be activated first, and then the fence event may be obtained.

S503. When the electronic device enters the fence, based on the fence event, the activation card and the first mapping relationship determine the first radio frequency parameter.

The electronic device may determine that it has entered the fence based on the fence event. When the electronic device enters the fence, it may determine the current first radio frequency parameter based on the currently entered fence, the activation card, and the first mapping relationship. Wherein, the first radio frequency parameter is an NFC radio frequency parameter currently used by the electronic device. The first mapping relationship may be the mapping relationship between the fence, the card, and the radio frequency parameters stored in the electronic device. For details, refer to Table 1.

The electronic device may store a first mapping relationship, and the first mapping relationship may be a mapping table.

Table 1

Table 1 shows a mapping table among fences, cards and radio frequency parameters. As shown in Table 1, the electronic device may store a set of main radio frequency parameters and n sets of compatible radio frequency parameters. Wherein, n, m and k are positive integers, and the above-mentioned card 1 to card m may be one of the above-mentioned bus cards, subway cards, door lock cards and the like. The radio frequency parameters include one or more of resonance frequency, carrier waveform, amplitude depth, receiving sensitivity, sleep parameters, etc. Electronic devices can communicate with NFC readers according to different radio frequency parameters. In the mapping relationship of different compatible radio frequency parameters, the mapping relationship among the compatible radio frequency parameters of the fence, the card and the radio frequency parameter is not limited. Wherein, one fence may correspond to one card, or multiple fences may correspond to one card, or one fence may correspond to multiple cards, or multiple fences may correspond to multiple cards. A set of main radio frequency parameters in Table 1 is the most commonly used NFC radio frequency parameters for electronic devices, while other sets of compatible radio frequency parameter electronic devices are used less frequently than the main radio frequency parameters.

It should be noted that Table 1 is only an example to illustrate a possible situation, and does not constitute a limitation.

In a possible implementation manner, the electronic device may look up radio frequency parameters corresponding to the fence and the activation card from Table 1 based on the determined current fence and the activation card. In one case, when there is no compatible radio frequency parameter corresponding to the fence and the card in Table 1, the electronic device determines to use the main radio frequency parameter, that is, the first radio frequency parameter is the main radio frequency parameter. For example, when it is detected that the electronic device enters the fence 1, and the activated card is card 5, there is no compatibility parameter of this mapping relationship in Table 1, and the electronic device can determine to use the main radio frequency parameter. In another case, when there is a compatible radio frequency parameter corresponding to the fence and the card in Table 1, the electronic device determines to use the corresponding compatible radio frequency parameter, that is, the first radio frequency parameter is a certain compatible radio frequency parameter. For example, when it is detected that the electronic device enters fence 1, and the activated card is card 1, based on the mapping relationship in Table 1, compatibility parameter 1 is determined, and the electronic device can determine to use compatibility parameter 1, that is, it can determine the current The first radio frequency parameter of is compatibility parameter 1.

After the electronic device determines the first radio frequency parameter, it may further determine a parameter switching flag. When the electronic device switches the first radio frequency parameter from the main radio frequency parameter to the compatible radio frequency parameter, the electronic device switches the parameter switching flag from the first number to the second number. Wherein, the first number indicates that the current radio frequency parameter is the main radio frequency parameter, and the second number indicates that the current radio frequency parameter is a compatible radio frequency parameter. When the electronic device switches the first radio frequency parameter from the compatible radio frequency parameter to the main radio frequency parameter, the electronic device switches the parameter switching flag from the second number to the first number. In the case that the electronic device keeps the main radio frequency parameter unchanged, the electronic device keeps the parameter switching flag as the first number. When the electronic device keeps the compatible radio frequency parameters unchanged or switches from one compatible radio frequency parameter to another compatible radio frequency parameter, the electronic device keeps the parameter switching flag at the second number. Among them, the parameter switching flag can be represented by a specific number, for example, the first number is "0", and the second number is "1". When the electronic device switches the first radio frequency parameter from the main radio frequency parameter to the compatible radio frequency parameter Next, the electronic device switches the parameter switching flag from "0" to "1".

It should be noted that there is a corresponding relationship between determining the radio frequency parameter and determining the parameter switching flag bit by the electronic device, but the execution sequence is not limited. The radio frequency parameters can be determined first, and then the parameter switching flag can be determined; or the parameter switching flag can be determined first, and then the radio frequency parameters can be determined.

The following exemplarily illustrates several possible situations of determining the first radio frequency parameter:

Case 1: Switch from main radio frequency parameters to compatible radio frequency parameters.

The first radio frequency parameter of the user before entering the fence is the main radio frequency parameter, and the corresponding NFC parameter of the card used after entering the fence is a compatible radio frequency parameter. As shown in FIG. 6 , when the electronic device never enters the first fence, the first radio frequency parameter is the main radio frequency parameter. After user A enters the first fence from point A, the electronic device detects the fence event and determines that the fence is the first fence (assuming that the first fence is fence 1). As shown in FIG. 7 , after the electronic device unlocks the smart door lock card, the electronic device can determine that the current activated card is the smart door lock card (assuming that the smart door lock card is card 1). Afterwards, the electronic device can search according to Table 1 and obtain that the radio frequency parameter corresponding to the fence 1 and the card 1 is the compatible radio frequency parameter 1. At this time, the electronic device can determine that the current first radio frequency parameter is the compatible radio frequency parameter 1. In addition, the electronic device can switch the parameter switching flag from the first number to the second number.

Case 2: Keep the main radio frequency parameters unchanged.

The first radio frequency parameter of the user before entering the fence is the main radio frequency parameter, and the corresponding NFC parameter of using the card after entering the fence is also the main radio frequency parameter. Before the electronic device enters the fence, the first radio frequency parameter is the main radio frequency parameter. After user A enters the first fence from point A, the electronic device detects the fence event and determines that the fence is the first fence (assuming that the first fence is fence 6). As shown in FIG. 7 , after the electronic device unlocks the smart door lock card, the electronic device can determine that the current activation card is the smart door lock card (assuming that the smart door lock card is card 5 ). Afterwards, the electronic device does not find the radio frequency parameters corresponding to the fence 6 and the card 5 in Table 1. At this time, the electronic device can determine that the current first radio frequency parameter is still the main radio frequency parameter. In addition, the electronic device may keep the parameter switching flag bit unchanged at the first number.

When the user switches cards in the same fence, the NFC radio frequency parameters corresponding to the cards before and after switching are the main radio frequency parameters. For example, user A is within the first fence, and the electronic device determines that the NFC radio frequency parameter (the first radio frequency parameter) used is the main radio frequency parameter when using one of the cards. When the electronic device uses another card, It is determined that the first radio frequency parameter is also the main radio frequency parameter, and the electronic device can keep the first radio frequency parameter unchanged as the main radio frequency parameter, and keep the parameter switching flag bit unchanged at the first number.

Case 3: The compatible radio parameters are switched to the main radio parameters.

When the user is in the same fence, when switching the activation card, the activation card used by the user before the switch is compatible with the radio frequency parameters, and the NFC parameter corresponding to the card used by the user after the switch is the main radio frequency parameter. The user is within the first fence, and the electronic device determines that the NFC radio frequency parameter (the first radio frequency parameter) used is a compatible radio frequency parameter when using one of the cards, and determines that the first radio frequency parameter is used when the electronic device uses another card. The radio frequency parameter is the main radio frequency parameter (second radio frequency parameter). The electronic device can switch the used radio frequency parameter from the compatible radio frequency parameter to the main radio frequency parameter, and switch the parameter switching flag from the second number to the first number.

Case 4: One compatible radio frequency parameter is switched to another compatible radio frequency parameter.

When the user is in the same fence, when switching the activation card, the activation card used by the user before the switch is a compatible radio frequency parameter, and the NFC parameter corresponding to the activation card used by the user after the switch is another compatible radio frequency parameter. The user is within the first fence, and the electronic device determines that the NFC radio frequency parameter (first radio frequency parameter) used is a compatible radio frequency parameter when using one of the cards, and determines that the electronic device uses another card. The first radio frequency parameter is another compatible radio frequency parameter (second radio frequency parameter), and the electronic device can switch the used radio frequency parameter from one kind of compatible radio frequency parameter to another kind of compatible radio frequency parameter, and keep the parameter switching flag as the first The second number remains unchanged.

The electronic device may store a first mapping relationship, and a specific method for determining the first mapping relationship will be described below.

Fig. 8 is a schematic diagram of a fence and the distribution of users using NFC cards disclosed in the embodiment of the present application. As shown in FIG. 8 , there are m NFC cards in the electronic device used by the user, and the user usually uses the above m cards in different fences. In fence 1, the electronic device can detect that there are two cards that the user can use, card 1 and card 2. At this time, the NFC radio frequency parameters corresponding to card 1 and card 2 are compatible with radio frequency parameter 1 (the slashed circle indicates is the radio frequency parameter and is the compatible radio frequency parameter 1). In fence 2, the electronic device can detect that there are two cards that the user can use, card 1 and card 3. At this time, the NFC radio frequency parameter corresponding to card 1 is the main radio frequency parameter (the black circle indicates that the radio frequency parameter is the main radio frequency parameter) parameter), the NFC radio frequency parameter corresponding to card 3 is compatible radio frequency parameter 2 (dotted circle indicates that the radio frequency parameter is compatible radio frequency parameter 2). In fence 3, the electronic device can detect that there are two cards that the user can use, card 1 and card 3. At this time, the NFC radio frequency parameters corresponding to card 1 are the main radio frequency parameters, and the NFC radio frequency parameters corresponding to card 3 are compatible radio frequency parameters. parameter2. The NFC compatible parameters corresponding to card 3 in fence 2 and fence 3 are compatible radio frequency parameter 2. In the fence k, the electronic device can detect that there is one card, card m, that can be used by the user. At this time, the NFC radio frequency parameter corresponding to the card m is the compatible radio frequency parameter n. In fence x, the electronic device can detect that there are two cards that the user can use, card 1 and card 2. At this time, the NFC radio frequency parameters corresponding to card 1 and card 2 are the main radio frequency parameters. Based on the distribution in Figure 8, the mapping relationship does not need to reflect the fences and cards corresponding to the main radio frequency parameters, but needs to reflect the fences and cards corresponding to the compatible radio frequency parameters, and the first mapping relationship stored in the electronic device can be the mapping shown in Table 1 surface.

In the first mapping relationship, each radio frequency parameter should be different. Radio frequency parameters can be distinguished based on different methods, as follows:

In a possible manner, the types of radio frequency parameters may be divided according to different manufacturers of NFC card reader devices. Since devices of different manufacturers use different NFC radio frequency parameters, the radio frequency parameters can be divided according to different manufacturers. For example, both manufacturer A and manufacturer B produce NFC card reader devices, and the devices a1 and a2 produced by manufacturer A can both communicate through the radio frequency parameter a. The device b1 produced by the manufacturer B can communicate through the radio frequency parameter b.

In another possible manner, the types of radio frequency parameters may be divided according to card types of different cards. Different types of public transportation cards and access control cards that users may use. For example, it is possible to set all types of public transport cards (for example, if a user uses two public transport cards in Shanghai and Shenzhen, and the corresponding radio frequency parameters of the two cards are the same) as one radio frequency parameter, and set all access control cards to one radio frequency parameter .

In yet another possible manner, radio frequency parameters may be divided according to different geographic locations. Since different users may work and live in different places, the types of radio frequency parameters can be divided according to different regions. For example, Beijing uses RF parameter 1, Shanghai uses RF parameter 2, Guangzhou uses RF parameter 3, and so on.

It should be noted that the above-mentioned division methods of radio frequency parameters are just examples, and the first mapping relationship may be determined according to the above-mentioned one or more division methods of radio frequency parameters, and other division methods may also be used, without limitation.

In addition, it should be noted that the first mapping relationship stored in the electronic device may include one set of mapping relationships, or may include multiple sets of mapping relationships. When the user uses NFC in different cities, the electronic device can use a set of mapping tables for all cities, or use different mapping tables for different cities. In a possible situation, the electronic device may include multiple sets of mapping tables, one set of mapping tables may be used in different regions, and one set of mapping tables may be used in multiple regions. For example, table a is used in city A, table b is used in city B, and table c is used in city C and city D. In another possible situation, the electronic device can include a set of mapping tables, and this set of mapping tables can be used by all regions to use NFC. For example, table a is used in all cities.

The first mapping relationship specifically reflects the range of activities of the user, the card used in the range of activities and the radio frequency parameters used by the NFC module of the electronic device, and the mapping relationship between the three. As shown in FIG. 8 , the first mapping relationship can be specifically closely related to the user, and this association enables the first mapping relationship to enable the electronic device to more accurately and quickly determine the radio frequency parameters used during NFC communication.

As time changes, the NFC card reader device may undergo adjustments such as updates and additions. Therefore, when the radio frequency parameters of the NFC card reader are adjusted, the first mapping relationship stored in the electronic device will also follow. Adjust to accommodate changes in the NFC reader used by the user. Several implementations of radio frequency parameter adjustment of NFC in Table 1 are specifically described below:

Embodiment 1: Add radio frequency parameters.

With the expansion of the range of NFC cards used by users and the increase of compatible radio frequency parameters corresponding to NFC card readers, there may be new compatible radio frequency parameters that are not stored in the first mapping relationship. Therefore, new compatible radio frequency parameters need to be added accordingly .

Fig. 9 is a schematic flowchart of radio frequency parameter adjustment disclosed in the embodiment of the present application. As shown in FIG. 9 , when the cloud server (that is, the cloud) obtains the parameter addition instruction, it can send the parameter addition instruction to the wallet of the electronic device (for example, the mobile phone may contain a wallet application). The parameter adding instruction is used to instruct the electronic device to add radio frequency parameters in the first mapping relationship. The parameter adding instruction may include radio frequency parameter information, fence information and card information, and the parameter adding instruction may also include adding a flag, for example, "00". There is a corresponding relationship between radio frequency parameter information, fence information and card information in the parameter addition command. After the wallet application receives the parameter addition instruction from the cloud server, it can send the parameter addition instruction to the NFC module of the electronic device. After the NFC module receives the parameter addition instruction from the wallet, it can add the radio frequency parameter of the first mapping relationship and the corresponding fence and card information based on the parameter addition instruction. That is, the radio frequency parameter can be stored in the first mapping relationship as a compatible radio frequency parameter, and the stored radio frequency parameter corresponds to the card and the fence. Then the NFC module can send an instruction to add a fence to the LBS module of the electronic device. After the LBS module receives the instruction to add a fence from the NFC module, it can add a fence event that can be monitored. Wherein, the adding fence instruction may include fence information and adding fence flags. Specifically, after the NFC module obtains the parameter adding instruction, it determines whether a new fence needs to be added to the first mapping relationship. When necessary, the NFC module can send an adding fence instruction to the LBS module, and the adding fence instruction can include a fence Information and additional fence flags can be included to place this new fence. The LBS module of the electronic device can obtain the fence event based on the adding fence instruction.

Exemplarily, the cloud server obtains the parameter addition instruction, and then sends the parameter addition instruction to the wallet application. Wherein, the parameter adding instruction includes fence 4, card 2 and radio frequency parameters, and adding flag "00". After the wallet application receives the parameter addition instruction from the cloud server, it can send the parameter addition instruction to the NFC module. After the NFC module receives the parameter addition instruction from the NFC, it determines that the parameters need to be added based on the addition flag "00", and the fence 4, card 2 and radio frequency parameters can be added to the first mapping relationship. For example, when Table 1 is the first mapping relationship, after the NFC module can add a row of correspondence, Table 1 can be changed to Table 2 for storage.

Table 2

Table 2 is another mapping table between fences, cards and radio frequency parameters disclosed in the embodiment of the present application. As shown in Table 2, compared with Table 1, Table 2 adds index 3, fence 4, card 2 and compatible radio frequency parameter 3.

The NFC module can send an instruction to add a fence to the LBS module. The adding fence instruction may include fence information (namely fence 4) and adding fence flag. After the LBS module receives the adding fence instruction, it can determine that it needs to add fence events that it needs to acquire based on the adding fence flag bit, specifically, it can add fence events that need to be monitored based on fence information.

Embodiment 2: Delete radio frequency parameters.

Assume that after the radio frequency parameters of an NFC card reader device are updated, it is not necessary to use compatible radio frequency parameters, but to use main radio frequency parameters or other existing compatible parameters. At this time, the electronic device will no longer use the compatible radio frequency parameter in the first mapping relationship, so that the cloud server can issue a parameter deletion instruction.

Fig. 10 is a schematic flowchart of another radio frequency parameter adjustment disclosed in the embodiment of the present application. As shown in FIG. 10 , when the cloud server obtains the parameter deletion instruction, it may send the parameter deletion instruction to the wallet application of the electronic device. The parameter deletion instruction is used to instruct the electronic device to delete the radio frequency parameters in the first mapping relationship. Wherein, the parameter deletion instruction may include radio frequency parameter information, fence information and card information. There is a corresponding relationship between radio frequency parameter information, fence information and card information in the parameter deletion instruction, and the parameter addition instruction may also include a deletion flag, for example, "01". After receiving the parameter deletion instruction from the cloud server, the wallet application can send the parameter deletion instruction to the NFC module of the electronic device. After the NFC module receives the parameter deletion instruction from the wallet, it can delete the radio frequency parameters and the corresponding fence and card information in the first mapping relationship based on the parameter deletion instruction. Afterwards, the deleted mapping relationship can be stored. Afterwards, the NFC module may send a fence deletion instruction to the LBS module of the electronic device, and the fence deletion instruction may include fence information and a fence deletion flag. After receiving the fence deletion instruction from the NFC module, the LBS module may determine the fence event to be acquired based on the fence deletion instruction.

Exemplarily, the cloud server obtains the parameter deletion instruction, and then sends the parameter deletion instruction to the wallet application. Wherein, the parameter deletion command includes fence 2, fence 3, card 3 and compatible radio frequency parameter 2, and the deletion flag "01". After receiving the parameter deletion instruction from the cloud server, the wallet application can send the parameter deletion instruction to the NFC module. After the NFC module receives the parameter deletion instruction from the NFC, it determines that the parameters in it need to delete the information in the first mapping relationship based on the deletion flag "01", and deletes the information in the row that is the same as the information in the parameter deletion instruction in Table 1. The fence 2, fence 3, card 3 and compatible radio frequency parameter 2 in the first mapping relationship may be deleted. For example, when Table 1 is the first mapping relationship, after the NFC module can delete a row of correspondence, Table 1 can be changed to Table 3 for storage.

table 3

Table 3 is another mapping table between fences, cards and radio frequency parameters disclosed in the embodiment of the present application. As shown in Table 3, compared with Table 1, Table 2 deletes index 2, fence 2, fence 3, card 3 and compatible radio frequency parameter 2.

The NFC module can send an instruction to delete the fence to the LBS module. The delete fence command may include fence information (that is, fence 2 and fence 3) and delete fence flags. After the LBS module receives the fence instruction, it can determine the fence event that needs to be deleted based on the fence flag bit, and specifically delete the fence events that need to be obtained based on the fence information, fence 2 and fence 3.

Embodiment 3: Updating radio frequency parameters.

When the user uses the NFC card, the corresponding NFC card reader device may be upgraded or the system is updated, which may cause the radio frequency parameters of the NFC card reader to change. Therefore, the electronic device needs to update the first mapping relationship Corresponding RF parameters.

Fig. 11 is a schematic flowchart of another radio frequency parameter adjustment disclosed in the embodiment of the present application. As shown in FIG. 11 , when the cloud server obtains the parameter update instruction, it may send the parameter update instruction to the wallet application of the electronic device. The parameter update instruction is used to instruct the electronic device to update the radio frequency parameters in the first mapping relationship. The parameter update instruction may include radio frequency parameter information, fence information, and card information. The parameter update instruction may also include an update flag, for example, "11". In the parameter update command, there is a corresponding relationship between the radio frequency parameter information, the fence information and the card information. After receiving the parameter update instruction from the cloud server, the wallet application can send the parameter update instruction to the NFC module of the electronic device. After the NFC module receives the parameter update instruction from the wallet, it can update the radio frequency parameters and the corresponding fence and card information in the first mapping relationship based on the parameter update instruction. Afterwards, the updated mapping relationship may be stored. The NFC module can determine whether the current fence information needs to be updated based on the parameter update instruction. In the case of needing to update the fence, the NFC module can send an update fence instruction to the LBS module of the electronic device, wherein the update fence instruction can include fence information and update fence signs bit. After receiving the updated fence instruction from the NFC module, the LBS module may determine the fence event to be acquired based on the updated fence instruction.

Exemplarily, after obtaining the parameter update instruction, the cloud server sends the parameter update instruction to the wallet application. Wherein, the parameter update instruction includes fence 2, fence 3, card 3 and compatible radio frequency parameter 5, and the update flag bit "11". After the wallet application receives the parameter update command from the cloud server, it can send the parameter update command to the NFC module. After the NFC module receives the parameter update instruction from NFC, it can update the current parameter information based on the flag "11", and can determine that the compatible radio frequency parameter needs to be updated as compatible radio frequency parameter 2 based on fence 2, fence 3 and card 3 and Table 1 , and then the compatible radio frequency parameter 2 in the first mapping relationship may be updated to the compatible radio frequency parameter 5. For example, when Table 1 is the first mapping relationship, after the NFC module can update a row of correspondence, Table 1 can be changed to Table 4 for storage.

Table 4

Table 4 is another mapping table between fences, cards and radio frequency parameters disclosed in the embodiment of the present application. As shown in Table 4, compared with Table 1, Table 4 updates compatible radio frequency parameter 2 to compatible radio frequency parameter 5.

Based on the fence 2 and the fence 3, it can be confirmed that the current fence information is the same as the updated fence information, therefore, there is no need to update the fence information. The NFC module does not need to send an update fence instruction to the LBS module.

Through the above-mentioned adjustment to the first mapping relationship, in the face of changes in the radio frequency parameters of the NFC card reader device, the electronic device can still adapt to this change, switch in advance or determine the used radio frequency parameters, so that the electronic device can improve the sensitivity of the electronic device to different NFC readers. The compatibility of the card device expands the communication range of the NFC module of the electronic device and improves the flexibility of the NFC communication.

Optionally, the radio frequency parameter can be switched to a certain compatible radio frequency parameter only when the NFC module of the electronic device receives a fence event of the fence in the first mapping relationship. Therefore, before acquiring the fence event, the electronic device can filter the fence event. In a possible situation, the NFC module of the electronic device may monitor the fence event broadcast by the LBS module based on the fence in the above first correspondence. For example, when the fence event broadcast by the LBS module is the fence in Table 1, the NFC can use the monitored fence event to obtain the first radio frequency parameter; otherwise, no further processing is required. In another possible situation, the LBS module of the electronic device may broadcast based on the fence event in the first mapping relationship, for example, only broadcast the fence event in Table 1 after the LBS acquires the fence event. That is, it can be understood that after the LBS module of the electronic device can receive all possible fence events, it needs to filter based on the fence sent by the first mapping relationship. At this time, the fence event acquired by the NFC module of the electronic device is only the first mapping relationship. Fence events for fences included in . Therefore, the efficiency of obtaining effective fence events can be improved.

In addition, when the electronic device swipes the card through the NFC card, and when the NFC module communicates with the NFC card reader device, the signal parameters between the two devices are determined according to the above-mentioned determined specifications of the first radio frequency parameter.

S504. The electronic device may determine the first radio frequency parameter as the main radio frequency parameter, and set the parameter switching flag to the first number.

When the electronic device exits the fence and/or exits the card activation state, the electronic device may determine that the currently used radio frequency parameter is the main radio frequency parameter. Specifically, when the parameter switching flag is the second number, the NFC module of the electronic device can determine the first radio frequency parameter as the main radio frequency parameter based on the fence state and/or the activation state of the card, and switch the parameter switching flag to number one.

In a possible implementation manner, when the parameter switching flag is the second number, the NFC module of the electronic device may switch the first radio frequency parameter based on the state of the fence. In the case that the fence event acquired by the electronic device is a fence event that exits the fence (for example, in Figure 6, user A travels to point B and the route thereafter), the first radio frequency parameter can be switched from the compatible radio frequency parameter to the main radio frequency parameter . For example, in the case of exiting the fence and not exiting the activation state; or, in the case of exiting the fence and exiting the activation state, the NFC module switches the first radio frequency parameter from the compatible radio frequency parameter to the main radio frequency parameter. Afterwards, the NFC module can switch the parameter switching flag from the second number to the first number. For example, switching from "1" to "0". In the case that the electronic device enters the fence, keep the current first radio frequency parameter unchanged, and keep the current parameter switching flag unchanged.

In another possible implementation manner, when the parameter switching flag is the second number, the NFC module of the electronic device may switch the first radio frequency parameter based on the activation status of the card. When the electronic device exits the activation state of the card (for example, after the user closes the user interface of (B) in FIG. Switch to main RF parameters. For example, when the card exits the activation state and the electronic device does not exit the fence; or, when the card exits the activation state and the electronic device exits the fence, the NFC module switches the first radio frequency parameter from the compatible radio frequency parameter to the main radio frequency parameter. Afterwards, the NFC module can switch the parameter switching flag from the second number to the first number. For example, switching from "1" to "0". In the case that the card remains activated, the current first radio frequency parameter and the current parameter switching flag remain unchanged.

In another possible situation, when the parameter switching flag is the second number, the NFC module of the electronic device may switch the first radio frequency parameter based on the activation state of the card and the fence state of the electronic device. When the electronic device exits the activation state of the card and the electronic device exits the enclosure, the first radio frequency parameter may be switched from the compatible radio frequency parameter to the main radio frequency parameter. For example, when the card exits the activation state and the electronic device exits the fence, the NFC module switches the first radio frequency parameter from the compatible radio frequency parameter to the main radio frequency parameter. Afterwards, the NFC module can switch the parameter switching flag from the second number to the first number. For example, switching from "1" to "0". In the case that the card remains activated or the electronic device enters the fence, the current first radio frequency parameter and the current parameter switching flag remain unchanged.

In addition, when the electronic device is just powered on, it may be determined that the current first radio frequency parameter is the main radio frequency parameter. In addition, the electronic device can also set the parameter switching flag to be the first number. That is, when the electronic device does not use the NFC card, try to keep the first radio frequency parameter as the main radio frequency parameter, and the parameter switching flag is the first number.

In the embodiment of the present application, before the user uses the NFC, the electronic device can determine the radio frequency parameters of the NFC that may be used based on the geographic fence where the user's electronic device is located and the currently used card. In this way, even if the parameters used by different NFC card readers are not the same, the electronic device switches or determines the radio frequency parameters of the wireless signal communicated between the two devices in advance, thereby improving the probability of a successful one-time communication between the two devices. In turn, the number of failed card swipes by the user can be reduced, and the user experience can be improved.

Please refer to Figure 12, Figure 12 is a schematic flowchart of another NFC radio frequency parameter compatibility method provided by the embodiment of the present application, the method can be executed by the electronic device shown in Figure 12, and the method can include but not limited to the following steps :

S1201. The electronic device acquires a fence event.

Wherein, for step S1201, reference may be made to step S501, and details are not repeated.

S1202. The electronic device acquires an activation card.

Wherein, for step S1202, reference may be made to step S502, and details are not repeated.

It should be noted that the execution order of step S1201 and step S1202 is not limited. Step S1201 can be executed first, and then step S1202 can be executed; or step S1202 can be executed first, and then step S1201 can be executed.

S1203. When the electronic device enters the fence, based on the fence event, activates the card and determines the first radio frequency parameter.

Wherein, for step S1203, reference may be made to step S503, and details are not repeated.

Fig. 13 is a schematic flow diagram of a user using an NFC card disclosed in an embodiment of the present application. As shown in FIG. 13 , user B moves forward along route 02 , and when user B enters the second fence, the electronic device used by user B can detect the fence event of entering the second fence. When user B travels to point D, as shown in (A) in FIG. 13 , user B's electronic device can display a user interface 30 for the user to open the smart door lock card, and the user interface 30 can include the smart door lock card. The user can bring the electronic device displaying the user interface 30 close to the NFC card reader (at this time, the NFC card reader is located at point D), and the electronic device and the NFC card reader can communicate to complete card swiping.

S1204. The electronic device acquires a card switching instruction, and switches the currently activated card based on the card switching instruction.

The NFC module of the electronic device can obtain the card switching instruction, and switch the currently activated card based on the card switching instruction.

In a possible implementation manner, when the user clicks to switch the current active card, the electronic device may respond to the above user switching operation, acquire a card switching instruction, and display the switched active card.

Exemplarily, as shown in (A) in FIG. 13 , when the user needs to use a public transportation card, the user can exit the current user interface 30 , and the electronic device can display the user interface 40 . As shown in (B) in FIG. 13 , the user interface 40 may include the card being activated by the user, the smart door lock card, and the currently unactivated card, the community access control card and the public transportation card. The user can click on the control of the public transportation card, so that the current activated one can be switched to the public transportation card. As shown in (C) of FIG. 13 , the electronic device may display a user interface 40, and the user interface 40 may include a switched card public transportation card.

In another possible implementation manner, the user does not need to click to switch the activation card as shown in FIG. 13 , and the NFC module of the electronic device can obtain the card switching instruction and switch the activation card.

Exemplarily, the electronic device may acquire the card switching instruction based on the fence event and the corresponding relationship between the fence and the card. Based on the first mapping relationship, a certain fence may correspond to multiple cards. The electronic device obtains a determination whether a fence needs to be switched based on the different locations that different cards are often used. When the activation card of the electronic device is the first card, and the position of the electronic device is within the space threshold range of the second card in the second fence, the electronic device can obtain the card switching instruction and switch the activation card from the first The first card switches to the second card.

Exemplarily, the electronic device can directly acquire the card switching instruction without user's operation. In step S1203, the activation card is a smart door lock card. The electronic device can detect the radio frequency signal of the surrounding NFC card reader, and judge the type of the NFC card reader based on the radio frequency signal. Afterwards, the electronic device can have a different type of NFC card reader from the currently used activation card, so as to generate a card switching instruction and switch the activation card. For example, if the electronic device determines that the type of NFC card reader is a POS machine at a subway entrance, the electronic device can use a public transportation card based on the card used. The public transportation card is different from the current activation card smart door lock card, and the electronic device can obtain the card switch command. The card switching instruction is used to switch the current active card switching from a smart door lock card to a public transportation card.

The above acquisition of the card switching instruction is only an exemplary description, and there are other ways of obtaining the card switching instruction, which are not limited.

S1205. The electronic device determines a second radio frequency parameter based on the activated card after switching, the fence event and the first mapping relationship.

After the electronic device acquires the card switching instruction, it may determine the activated card after switching based on the card switching instruction. Afterwards, the second radio frequency parameter may be determined based on the activated card after switching, the fence event, and the first mapping relationship. Wherein, the second radio frequency parameter is a determined NFC radio frequency parameter used by the electronic device after the electronic device switches the card. For a specific method of determining radio frequency parameters, reference may be made to relevant descriptions in step S503, and details are not repeated.

After the electronic device re-determines the first radio frequency parameter, the second radio frequency parameter may need to be switched or may remain unchanged. Several specific possible situations are described below:

In a possible situation, when the first radio frequency parameter determined by the electronic device in step S1203 is the main radio frequency parameter, the first radio frequency parameter re-determined by the electronic device may be the main radio frequency parameter, or one of the compatible radio frequency parameters. parameter. In the case that the determined second radio frequency parameter is the main radio frequency parameter, the electronic device may keep the second radio frequency parameter unchanged as the first radio frequency parameter, and keep the current parameter switching flag unchanged at the first number. In the case that the second radio frequency parameter is a compatible radio frequency parameter, the electronic device can switch the used radio frequency parameter from the primary radio frequency parameter to a compatible radio frequency parameter, and switch the parameter switching flag from the first number to the second number.

In another possible situation, when the first radio frequency parameter determined by the electronic device in step S1203 is a compatible radio frequency parameter, the second radio frequency parameter determined by the electronic device may be the main radio frequency parameter, or another compatible radio frequency parameter. parameters, and may also be the same type of compatibility radio frequency parameters. In the case that the determined second radio frequency parameter is the main radio frequency parameter, the electronic device can switch the radio frequency parameter used by the electronic device from the compatible radio frequency parameter to the main compatible radio frequency parameter, and switch the parameter switching flag from the second number to the first number. In the case that the determined second radio frequency parameter is another compatible radio frequency parameter, the electronic device can switch the radio frequency parameter used by the electronic device from one compatible radio frequency parameter to another compatible radio frequency parameter, and maintain the current parameter switching flag Bit is unchanged for the second number. In the case that the determined second radio frequency parameter is the same compatible radio frequency parameter, the electronic device may keep the current radio frequency parameter and the parameter switching flag used by the electronic device unchanged.

After the electronic device determines the second radio frequency parameter (the currently used radio frequency parameter), the electronic device can communicate with the NFC card reader to complete data exchange. As shown in (C) in Figure 13, when the user is at point D in the second fence, the user can hold the electronic device displaying the user interface 50 close to the gate of the subway to complete payment by swiping the card. It should be noted that the users at point D and point C in the second fence in Figure 13 use smart door lock cards and public transport cards respectively for illustrative purposes only, and may also be other two different cards , which is not limited here.

It should be noted that, when the electronic device is in a certain enclosure, the number of times the electronic device switches the activation card may be one time or multiple times, which does not constitute a limitation. The embodiment of the present application is to illustrate the method of determining the radio frequency parameters of the electronic device before and after switching the activation card once.

In the embodiment of the present application, the electronic device can use one NFC card or multiple NFC cards in the same enclosure. When the user uses different NFC cards, the electronic device needs to switch the currently activated card. Before and after the switch, the electronic device can pass through the fence and the switched card again to determine the radio frequency parameters to be used by itself, thus The determination of the radio frequency parameters used can be completed before the user's electronic device communicates with the NFC card reader, thereby reducing the failure of swiping the card due to parameter mismatch during the communication process, so as to improve the success rate of the user's NFC radio frequency communication, and then Can improve user experience.

An NFC radio frequency parameter switching scenario provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

Fig. 14 is a schematic flow diagram of another user using an NFC card disclosed in this embodiment.

When the electronic device enters and exits the fence, the electronic device adjusts the NFC radio frequency parameters used based on the change of the fence. In the case of entering the fence, the electronic device can determine the radio frequency parameter based on the fence event of entering the fence and the activation card; in the case of exiting the fence, the electronic device can determine the main radio frequency parameter to be used based on the fence event of exiting the fence.

When the electronic device is outside the fence, that is, when the NFC module of the electronic device does not receive any fence event, at this time, the radio frequency parameter currently used by the electronic device is the main radio frequency parameter, and then the electronic device can enter the fence. As shown in FIG. 14 , user C can carry the electronic device forward along the route 03 . In the case that user C enters into X, the electronic device can acquire the fence event of entering the third fence. At this point, the electronic device can acquire the current activation card, for example, the smart door lock card is the current activation card. Since the fence event is entering the third fence and the activation card is a smart door lock card, the electronic device can determine the first radio frequency parameter based on the first mapping relationship. For example, the electronic device may determine that the current radio frequency parameter is the compatible radio frequency parameter 2 based on Table 1 (assuming that the third fence is fence 3, and the smart door lock card is card 3). That is, the electronic device can switch the currently used radio frequency parameter from the main radio frequency parameter to the compatible radio frequency parameter 2.

When the user reaches point Y in FIG. 14 , the electronic device is close to the NFC card reader at the door, and the electronic device can perform radio frequency communication with the NFC card reader through compatible radio frequency parameter 2. It should be noted that after the user's electronic device communicates with the NFC card reader, the user can click on the electronic device to confirm the activation of the card, or can confirm the activation of the card without the user's operation, and there is no limitation in this process.

When the user travels to point Z in FIG. 14 , the NFC module of the electronic device may receive a fence event that the user exits the third fence. The electronic device switches the currently used radio frequency parameter from the compatible radio frequency parameter 2 to the primary radio frequency parameter. Specifically, the electronic device determines the current parameter switch flag bit when it acquires the exit fence. When the parameter switching flag is the second number, the electronic device can switch the second number to the first number, and switch the compatible radio frequency parameter 2 to the main radio frequency parameter.

It should be understood that in all the above-mentioned embodiments, when the electronic device needs to switch the parameter switching flag and the radio frequency parameter used, it can first switch the parameter switching flag, and then switch the used radio frequency parameter; it can also switch the used radio frequency parameter first. The radio frequency parameters, and then switch the parameter switching flag. That is, the sequence of execution is not limited. In addition, the first mapping relationships shown in all the tables (Table 1 to Table 4) are only illustrative and not limiting.
