Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to Save the electric quantity of the electronic equipment and improve the cruising ability of the electronic equipment, a wireless communication chip (WiFi chip) in the electronic equipment is in a PSM (Power Save Mode), if the router caches data to be sent to the electronic equipment, the wireless communication chip exits the PSM Mode, and then receives the data from the router; after exiting the PSM mode, the wireless communication chip may be in Wake UP mode, and receive the data from the router, the wireless communication chip is in Wake UP mode, and the process of receiving the data from the router may accelerate the consumption of the power of the electronic device, so how to extend the time that the wireless communication chip is in PSM mode, and reduce the number of times that the wireless communication chip receives the data from the router is a problem that those skilled in the art need to solve urgently, and also to save the power of the electronic device, and to improve the endurance of the electronic device.
Illustratively, the PSM mode is a power saving mode of the 802.11 protocol, and the Wake UP mode is an awake mode of the 802.11 protocol.
Based on this, embodiments of the present application provide a processing method and apparatus to achieve the purpose of prolonging the time that the wireless communication chip is in the PSM mode and reducing the number of times that the wireless communication chip receives data from the router. Before the technical solution provided by the embodiment of the present application is introduced, a hardware environment applied by the present application is introduced.
As shown in fig. 1, an architecture diagram of a hardware environment applied in the embodiment of the present application is shown, where the hardware environment includes: at least one electronic device 11, a router 12, and at least one server 13.
The electronic device 11 may be any electronic product capable of interacting with a user through one or more ways, such as a keyboard, a touch PAD, a touch screen, a remote controller, a voice interaction device, or a handwriting device, for example, a mobile phone, a notebook computer, a tablet computer, a palm computer, a personal computer, a wearable device, a smart television, a PAD, and the like.
The server 13 may be one server, a server cluster composed of a plurality of servers, or a cloud computing server center. The server 13 may include a processor, memory, and a network interface, among others.
For example, different servers 13 may correspond to different clients, for example, communication type clients, video type clients. The client may be an application client or a web page version client, for example.
Illustratively, one or more clients may be installed in the electronic device 11.
It should be noted that fig. 1 is only an example, and the types of the electronic devices may be various, and are not limited to the notebook computer, the smart phone, the PAD, and the personal computer in fig. 1. Fig. 1 shows 4 electronic devices and 2 servers, and in practical applications, the numbers of the electronic devices and the servers may be determined based on practical situations, and the application does not limit the numbers of the electronic devices and the servers.
The interaction process between any server 13, router 12, and any electronic device 11 is the same, and therefore, the interaction process will be described below by taking one server 13, router 12, and one electronic device 11 as an example. As shown in fig. 2, a schematic diagram of an interaction process between a server, a router, and an electronic device provided in the embodiment of the present application is shown, where the interaction process includes steps S201 to S203.
Step S201: the server 13 obtains a data transmission request including data to be transmitted, a destination communication address, and a source communication address, and sends the data transmission request to the router 12.
Wherein the destination communication address characterizes the address of the electronic device 11 receiving the data. The source communication address is the address of the server 13.
Illustratively, one server 13 may transmit data to one or more electronic devices 11; different servers 13 may transmit data to the same electronic device.
Illustratively, the Address of the electronic device 11 may include an IP (Internet protocol Address) Address, and/or a MAC (Media Access Control) Address. Illustratively, the IP address of the electronic device may be a public network IP address or a private network IP address.
Illustratively, the source communication address of the server may include: the IP address of the server, or source address, may include: the IP address and port number of the server.
For example, the types of the clients corresponding to the server 13 are different, and the obtained data transmission requests are different, which is described below by way of example.
Firstly, the type of the client is a video client.
Illustratively, the server 13 obtains a data transmission request in the case of video update, wherein the data to be transmitted may be a video update notification message.
Illustratively, the data transmission request may be generated by the server 13, and illustratively, the data transmission request may be received by the server 13.
And secondly, the type of the client is a communication client.
Illustratively, the server 13 obtains the data transmission request in the case of a communication demand, for example, in the case of text communication, voice communication or video communication between the user a and the user B. For example, if user a sends text information to user B, the server 13 may receive a data transmission request sent by an electronic device held by user a.
Step S202: the router 12 generates a management frame in response to the data transmission request, and transmits the management frame to the electronic device 11.
A router is a hardware device that connects two or more networks, acts as a gateway between the networks, and is a dedicated intelligent network device that reads the destination communication address in each data transfer request and then decides how to transmit.
The router 12 is capable of understanding different communication protocols, such as the ethernet protocol used by a certain local area network, the TCP/IP protocol used by the internet. Thus, the router can analyze the destination communication addresses of the data transmission requests transmitted by various different types of networks, and convert the addresses of the non-TCP/IP networks into TCP/IP addresses or vice versa; and transmitting the data in each data transmission request to the designated position according to the selected routing algorithm according to the optimal route. The router may connect a non-TCP/IP network to the internet.
Illustratively, if the communication protocol between the server 13 and the router 12 is different from the communication protocol between the router and the electronic device 13, the router 12 needs to construct management frames and data frames that satisfy the communication protocol between the electronic device 13.
The router 12 may resolve the addresses in the data transfer request, i.e., the destination communication address and the source communication address. First data indicating a device to which the data obtained by the router belongs and second data indicating a source of the data are thus available.
For example, if the router obtains a plurality of data belonging to different devices, the first data is used to indicate the devices to which the plurality of data obtained by the router belong, respectively. The second data is used for indicating the source corresponding to the data respectively.
Illustratively, if the router obtains one or more data belonging to the same device, the first data is used to indicate a device to which the plurality of data obtained by the router belong in common. The second data is used for indicating the source corresponding to the data respectively.
The device to which the data obtained by the router belongs is the device to receive the data carried in the data transmission request.
Illustratively, router 12 may generate a management frame that includes the first data as well as the second data.
In an alternative implementation, router 12 may send the management frame to one or more electronic devices that have an association with router 12.
Illustratively, the process of establishing the association relationship between the electronic device 11 and the router 12 is as follows: when the electronic device 11 is connected to the network, it needs to send an Association initiation Request (Association Request) to the router 12, and the router feeds back an Association Response frame (Association Response), thereby establishing an Association relationship between the electronic device 11 and the router 12.
For example, in the process of establishing the Association relationship, the router may assign an AID (Association Identifier) to the electronic device, and the Association corresponding frame fed back to the electronic device by the router may include the AID assigned to the electronic device by the router. The AIDs corresponding to different electronic devices are different.
For example, the first data may include data identification corresponding to AIDs of one or more electronic devices, and for example, if the data identification corresponding to the AIDs of the electronic devices is a first identification, the characterizing router obtains data belonging to the electronic device, and if the data identification corresponding to the AIDs of the electronic devices is a second identification, the characterizing router does not obtain data belonging to the electronic device.
Illustratively, the first identifier includes one or more of a number, a letter, and a special character, and the second identifier is one or more of a number, a letter, and a special character, and the first identifier is different from the second identifier.
Illustratively, the second data includes sources of data respectively corresponding to AIDs of the one or more electronic devices. The server corresponds to the client, so the source of the data can represent the client corresponding to the data, for example, if the source of the data is a WeChat server, the client corresponding to the data is a WeChat client, and if the source of the data is a jitter Server, the client corresponding to the data is a jitter client.
Step S203: for any electronic device 11, if the wireless communication chip of the electronic device 11 is in the power saving mode, the management frame from the router 12 is monitored, and whether to exit the power saving mode is determined based on the first data and the second data included in the management frame.
It should be noted that the wireless communication chip is in the power saving mode regardless of the state of the electronic device, and in the power saving mode of the wireless communication chip, the electronic device may be in any state, for example, in a bright screen state or a dark screen state, and the electronic device may operate one or more clients or may not operate any client.
Illustratively, the wireless communication chip may be any one of a BCM4325 chip, a BCM4329 chip, a BCM4330 chip, a BCM4390 chip, and the like.
Illustratively, the wireless communication chip may also monitor the management frame from the router 12 after exiting the power saving mode.
In the related art, when the wireless communication chip is in the power saving mode, if the first data indicates that the router has obtained the data belonging to the electronic device 11, the wireless communication chip exits the power saving mode, and if the first data indicates that the router has not obtained the data belonging to the electronic device 11, the wireless communication chip is maintained in the power saving mode. In the embodiment of the present application, when the wireless communication chip is in the power saving mode, whether to exit the power saving mode is not determined only according to the first data. Instead, whether to exit the power saving mode is determined according to the first data and the second data, that is, the wireless communication chip may still be in the power saving mode under the condition that the first data indicates that the router obtains the data belonging to the electronic device 11, so that the time that the wireless communication chip is in the PSM mode is prolonged, the frequency of receiving the data from the router by the wireless communication chip is reduced, the electric quantity of the electronic device is saved, and the cruising ability of the electronic device is improved.
It will be understood by those skilled in the art that the foregoing electronic devices and servers are merely exemplary and that other existing or future electronic devices or servers may be suitable for use with the present disclosure and are intended to be included within the scope of the present disclosure and are hereby incorporated by reference.
The following describes a processing method provided in an embodiment of the present application with reference to the drawings. As shown in fig. 3, a flowchart of a processing method applied to a wireless communication chip in an electronic device according to an embodiment of the present application is provided, where the method includes steps S301 to S303.
Step S301: the management frame from the router is monitored if the wireless communication chip of the electronic device is in a power saving mode.
The management frame includes first data indicating a device to which the data obtained by the router belongs and second data indicating a source of the data.
For example, the first data may include data identification corresponding to one or more devices respectively.
For example, the second data may include sources of data corresponding to one or more devices, respectively.
For example, the source of the data may be an IP address of a server, and since the server corresponds to the client, the client corresponding to the data source may be determined based on the data source.
For example, the source of the data may include an IP address and a port number of the server, and since the IP address of the server corresponds to the client and the port number of the server corresponds to the functional module of the client, the functional module of the client may be determined based on the source of the data.
For example, the port number a of the server corresponds to the function module 1 of the client, that is, the server sends data related to the function module 1 to the client through the port number a, for example, a friend circle function of the communication client, the port number a of the server sends data related to the friend circle function to the client, and after receiving the data, the client can successfully refresh the friend circle, so as to show the latest movement of a friend to the user.
Illustratively, different port numbers of the server correspond to different functional modules of the client.
In an optional implementation manner, the management frame may be a beacon packet. Illustratively, the first data is located in a TIM (Traffic Indication Map) field included in the beacon packet, where the TIM field belongs to Tagged Parameters in IEEE 802.11Wireless Management. Tagged Parameters may also include second Data, which may be a BDH (bitmap Data header) field, which is subsequently specified collectively.
Illustratively, the TIM field includes a Bitmap control field, a Partial Virtual Bitmap field, and the first data may be characterized by the Bitmap control field and the Partial Virtual Bitmap field.
Fig. 4 is a schematic diagram of a relationship between a Bitmap control field and a partial virtual Bitmap field provided in the embodiment of the present application.
Illustratively, the Bitmap control field is also divided into two parts: x0Is used to indicate whether multicast/broadcast packets are buffered, this is a special bit. If 1, then there is multicast/broadcast data buffered, if 0, then there is no multicast/broadcast data buffered, only unicast data buffered. X1To X7(circled by a dotted line in fig. 4) is used to identify a Bitmap Offset, indicating the Offset of the AID.
X of Bitmap control field assuming no multicast/broadcast packet is buffered0For 0, assuming that the router 12 obtains the minimum value of the AID of the electronic device to which one or more pieces of data respectively belong is 100, and the router obtains only the data corresponding to the electronic devices with AID 100 and AID 103, since the minimum number from 100 is 8 × 2^2+8 × 2^3 ^ 96, X is1To X7The values are in turn 0110000. Since 100 ═ 96+4, assuming the first flag is 1 and the second flag is 0, then the offset of the PartialVirtualBitmap field is 00001001.
Illustratively, the PartialVirtualBitmap is a field of variable length. And if the router caches the data corresponding to the AIDs, the bit number occupied by the partial VirtualBitmap is more than 8.
In an optional implementation manner, the management frame may be a beacon packet. For example, the first data may be located in a TIM (Traffic Indication Map) field included in the beacon message. The second Data may be a BDH (bitmap Data header) field, where the BDH field belongs to Tagged Parameters added at the end of Tagged Parameters of the beacon packet.
Illustratively, the TIM field includes a Bitmap control field, a PartialVirtualBitmap field, and the first data may be characterized by the Bitmap control field and the PartialVirtualBitmap field. Referring specifically to fig. 4, the detailed description is omitted here.
Illustratively, the BDH field may be a parameter of a variable field size. Fig. 5 is a diagram illustrating a data structure of a BDH according to an embodiment of the present invention.
As shown in fig. 5, the BDH field may include 5 parts, wherein the first part 51 is a fixed value for indicating the protocol types adopted by the BDH field for the second part to the fourth part; the second part Taglenggth 52 is the number of bytes occupied by the third part to the fifth part in total; the OUI53 in the third part is the identifier of the manufacturer of the protocol used for making the BDH field; the fourth part OUI type54 is the type of protocol; at least one fifth portion 55, each fifth portion 55 being a source of data corresponding to one or more AIDs respectively.
The following explains the above section 5 by way of example.
For example, the first part may be located in the first byte of the BDH field, e.g., 0xdd, and 0xdd indicates that the BDH field is a vector specific field. The second part of Tag length may be located at byte 1 of the BDH field, and the third part may be located at byte 3 to byte 5 of the BDH field, for example, the third part OUI is Motorola id F0-D7-AA; the fourth part may be located at the 6 th byte of the BDH field, for example, the fourth part OUI type is 0x 02.
For example, the number of bytes occupied by the 5 parts included in the BDH is only an example, for example, the number of bytes occupied by each of the first part to the fifth part may be any positive integer, and for example, the number of bytes occupied by the second part Tag length is 2, 3, 4, 5, ….
For example, if the BDH field is a vendor specific field, the number of bytes occupied by the second portion of Tag length is 1, in which case the fifth portion contains at most 10 sources of data corresponding to AIDs respectively.
For example, the BDH field may not be a vendor specific field, but other custom fields.
The reason why the fifth part includes data corresponding to 10 AIDs at most will be described below.
It can be understood that the number of bytes occupied by the IP address is 4 to 16, wherein the number of bytes occupied by the IP address of Ipv4 is 4, the number of bytes occupied by the IP address of Ipv6 is 16, the number of bytes occupied by the type of IP address is 2, wherein the protocol type of Ipv4 is 0x0800, the protocol type of Ipv6 is 0x86dd, the number of bytes occupied by the port number is 2, and the fifth part occupies 251 bytes at most since the third part and the fourth part occupy 4 bytes.
Fig. 5 shows three AID structures 551, and the maximum number of bytes occupied by one AID structure, i.e., the number of bytes occupied by AID + the number of bytes occupied by length + the number of bytes occupied by the type of IP address + the number of bytes occupied by port number, i.e., 1+2+2+16+2, 23. Where length represents the number of bytes occupied by Data (part shown in fig. 5). Since 251 ÷ 23 ÷ 10.9, the fifth part contains at most 10 sources of data corresponding to the AIDs.
For example, one BDH field may include one or more fifth parts.
Step S302: and analyzing the management frame to obtain first data and second data.
For example, the Bitmap control field and the partial virtual Bitmap field included in the TIM field included in the management frame may be parsed to obtain the first data, and the BDH field may be parsed to obtain the second data.
Step S303: determining whether to exit the power saving mode based on the first data and the second data.
In the related art, if the first data indicates that the router has acquired the data belonging to the electronic device 11, the power saving mode is exited, and if the first data indicates that the router has not acquired the data belonging to the electronic device 11, the power saving mode is maintained. In the embodiment of the present application, when the first data indicates that the router obtains the data belonging to the electronic device 11, the wireless communication chip may exit the power saving mode only if the second data satisfies a certain condition.
In the processing method applied to the wireless communication chip provided by the embodiment of the application, when the wireless communication chip is in a power saving mode, a management frame from a router is monitored, wherein the management frame comprises first data used for indicating a device to which data obtained by the router belongs and second data used for indicating a source of the data; the wireless communication chip of the electronic device does not determine whether to exit the power saving mode only according to the first data, namely, does not exit the power saving mode only under the condition that the first data indicates that the router obtains the data belonging to the electronic device, but determines whether to exit the power saving mode according to the first data and the second data, namely, the wireless communication chip can still be in the power saving mode under the condition that the first data indicates that the router obtains the data belonging to the electronic device, so that the time that the wireless communication chip is in the PSM mode is prolonged, the times that the wireless communication chip receives the data from the router are reduced, the electric quantity of the electronic device is saved, and the cruising ability of the electronic device is improved.
In an alternative implementation manner, there are various implementation manners of step S303, and the present embodiment provides but is not limited to the following manners, and the implementation manner of step S303 includes three cases.
In the first case: if the router indicated by the first data does not obtain the target data belonging to the electronic equipment, the wireless communication chip is maintained in the power saving mode.
In the second case: if the first data indicate that the router obtains target data belonging to the electronic equipment, and the second data indicate that the source of the target data does not belong to a preset source, the wireless communication chip is maintained in the power saving mode.
In the third case: and if the first data indicate that the router obtains target data belonging to the electronic equipment and the second data indicate that the source of the target data belongs to a preset source, the wireless communication chip exits the power saving mode.
In both the first and second cases, the wireless communication chip is in a power saving mode, and in the third case, the wireless communication chip exits the power saving mode.
In an alternative implementation manner, there are various manners of setting the preset source, and the embodiments of the present application provide, but are not limited to, the following two manners.
First, the electronic device automatically sets the default source.
For example, the electronic device may automatically set the predetermined source based on the remaining power.
For example, if the processor of the electronic device detects that the remaining power of the electronic device is less than the first threshold, the IP address of the server corresponding to the communication-type client is set as the preset source. Or if the processor of the electronic device detects that the remaining power of the electronic device is less than the first threshold, setting the IP address and the port number of the server corresponding to the communication module of the communication type client as a preset source. The processor of the electronic device writes a predetermined source into the wireless communication chip.
For example, the electronic device may set the preset source based on the state of the client, for example, set the IP address (or the IP address and the port number) of the server corresponding to the client in the running state as the preset source. The IP address (or IP address and port number) of the server corresponding to the client that is not in the running state is not a preset source.
For example, the electronic device may set an IP address (or an IP address and a port number) of a server corresponding to the client, which is exposed at the front end of the electronic device within a preset time, as a preset source.
For example, the processor of the electronic device may write the predetermined source to the wireless communication chip.
Second, the user manually sets the default source.
In an optional implementation manner, the processing method applied to the wireless communication chip further includes: receiving a write-in request, wherein the write-in request carries a white list set by a user, and the white list comprises one or more preset sources; and responding to the write request, and storing the white list.
Illustratively, the user may set the predetermined source via a user interface presented by the electronic device. Specific modes include, but are not limited to, the following two.
The first implementation includes steps a11 through a 14.
Step A11: and if the operation of setting the white list is detected, displaying a user interface, wherein one or more application icons are displayed on the user interface.
For example, the operation of setting the white list may be a voice operation, a touch operation, or a gesture operation.
Step A12: determining at least one application icon from the one or more application icons.
Step A13: and acquiring the IP address of the server corresponding to the at least one application icon.
Step A14: and adding the IP address of the server corresponding to the at least one application icon to the white list.
The second implementation includes steps a21 through a 26.
Step A21: and if the operation of setting the white list is detected, displaying a user interface, wherein one or more application icons are displayed on the user interface.
Step A22: determining at least one application icon from the one or more application icons.
Illustratively, the application icon of the application program may be a literal name, or, an image.
Step A23: and displaying the icon of the functional module corresponding to the at least one application icon.
For example, the icon of the function module may be a name or an image of the function module.
Step A24: and determining the icon of at least one functional module from the icons of the functional modules corresponding to the at least one application icon.
Step A25: and acquiring an IP address of a server corresponding to the at least one application icon and a port number of the server corresponding to one or more functional modules contained in the at least one application, wherein data corresponding to the functional modules contained in one application is sent through the port number of the server corresponding to the functional modules.
Step A26: and adding the IP address of the server corresponding to the at least one application and the port number of the server corresponding to one or more functions contained in the at least one application to the white list.
In an optional implementation manner, a black list may also be set, the preset source is not included in the black list, and the process of setting the black list is the same as the process of setting the white list, which is not described herein again.
The following describes a black list and a white list by taking a process of determining whether the target data indicated by the second data is a preset source as an example.
Comparing the source of the target data to the whitelist; and if the source of the target data is matched with any preset source contained in the white list, determining that the source of the target data indicated by the second data comprises a preset source. If the source of the target data does not match any preset source contained in the white list, determining that the source of the target data indicated by the second data does not include a preset source.
Comparing the source of the target data with the preset blacklist; and if the source of the target data is matched with any source contained in the preset list, determining that the source of the target data indicated by the second data does not comprise a preset source. And if the source of the target data is not matched with any source contained in the preset list, determining that the source of the target data indicated by the second data comprises a preset source.
In an alternative implementation manner, after the wireless communication chip exits the power saving mode, the processing method further includes the following steps B1 to B3.
Step B1: and sending a request frame to the router, wherein the request frame is used for requesting target data corresponding to the electronic equipment.
Illustratively, the request frame may be a PS-Poll frame.
In an optional implementation manner, the Backoff may be performed after the electronic device exits the power saving mode, and after the Backoff is completed, the PS-Poll frame is sent to the router. Illustratively, the PS-Poll frame includes the AID of the electronic device.
Step B2: and receiving a data frame which is sent by the router and contains the target data.
In an optional implementation manner, after receiving the request frame, the router feeds back an ACK (acknowledgement character) to the electronic device, and after sending the ACK, the router generates a data frame based on the target data and sends the data frame to the electronic device; or after the router receives the request frame, the data frame is generated directly based on the target data without feeding back the ACK, and the data frame is sent to the electronic equipment.
In an optional implementation manner, after receiving the data frame, the electronic device feeds back ACK to the router; or after receiving the data frame, the electronic device does not feed back the ACK to the router.
The amount of data carried in one data frame is constant, so the target data can be carried by one or more data frames, i.e. the data carried by one or more data frames constitutes the target data.
For example, the data frame carries a More data field, and if the More data field in the data frame received by the electronic device is equal to 1, it indicates that the router has not finished sending the target data belonging to the electronic device, so it is necessary to return to step B1 until the received data frame carries the More data field equal to 0, that is, the router has finished sending the target data belonging to the electronic device.
Step B3: and entering the power saving mode after the target data is received.
In summary, in the processing method applied to the electronic device, when the first data indicates that the router obtains the target data belonging to the electronic device, the second data is required to satisfy a certain condition, for example, the second data indicates that the source of the target data includes a preset source, the wireless communication chip will exit the power saving mode, otherwise, the wireless communication chip remains in the power saving mode. Thereby saving the electric quantity of the electronic equipment. For example, if the second data indicates that the source of the target data includes a preset source, it indicates that the target data belonging to the electronic device and obtained by the router includes data required by the electronic device, and therefore, the wireless communication chip is required to exit the power saving mode, and send the target data belonging to the electronic device and obtained by the router to the electronic device.
For example, one server may send one or more data to the same electronic device, and different servers may send one or more data to the same electronic device, it is understood that the source of the one or more data belonging to the electronic device includes a preset source, which indicates that at least part of the one or more data belonging to the electronic device obtained by the router is data required by the electronic device.
For example, after the wireless communication chip exits the power saving mode, the router may transmit all the obtained data belonging to the electronic device.
For example, after the wireless communication chip exits the power saving mode, the router may send the obtained data, which is from a predetermined source, of all data belonging to the electronic device.
