Description

Physical link establishment method and electronic equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method for establishing a physical link and an electronic device.

Background

Short-distance wireless communication technologies between devices, such as wireless fidelity peer to peer (Wi-Fi p2 p) technology, bluetooth (BT) technology, etc., provide great convenience to users. Taking Wi-Fi p2p technology as an example, two devices can establish a Wi-Fi p2p physical link based on the Wi-Fi p2p technology and further establish a logical link, so that data can be directly transmitted between the two devices to complete services such as file transmission, screen projection, online games and the like.

However, at the same time, the Wi-Fi p2p physical links that a device can establish are limited, typically 1 or 2. If the Wi-Fi p2p physical link between two current devices is occupied by one application program and other application programs need to transmit data, the Wi-Fi p2p physical link can be obtained only in a preempting, reestablishing or waiting mode, and the problem of low efficiency exists.

In a first aspect, the present application provides a method for establishing a physical link, where the method is performed by a first electronic device, the first electronic device includes a first communication interface module and a first service module, and a second electronic device includes a second communication interface module, and the method includes: the first communication interface module receives a first connection request sent by the first service module, wherein the first connection request is used for indicating the first communication interface module to establish a first physical link; responding to the first connection request, the first communication interface module acquires a first total count value, wherein the first total count value is stored in the first electronic device and represents the effective request times of the first electronic device and the second electronic device to the first physical link, the effective request times are obtained by counting the effective connection request times and the effective disconnection request times, and the initial value of the first total count value is 0; and under the condition that the first total count value is greater than 0, the first communication interface module sends a first multiplexing connection request to the second communication interface module, and adds one to the first total count value, wherein the first multiplexing connection request is used for requesting the second communication interface module to multiplex a first physical link.

The first total count value is greater than 0, which indicates that the number of valid requests of the first physical link by the current first electronic device and the second electronic device is greater than 0, indicating that the current first physical link is established, and thus the first physical link can be multiplexed.

Optionally, the first connection request may include one or more of service identification information corresponding to the first service module, physical address information of the second electronic device, a link type of the first physical link, and the like. The service identification information may be, for example, a Process Identification (PID) corresponding to the first service module. The link type may be, for example, one of a Wi-Fi p2p link, a bluetooth Basic Rate (BR) link, a bluetooth Socket (Socket) link, or a bluetooth Enhanced Data Rate (EDR) link, etc.

Optionally, the first multiplexing connection request may include one or more of physical address information of the first electronic device and a link identifier of the first physical link.

Optionally, the first communication interface module may directly add one to the first total count value when it is determined that the first total count value is greater than 0, or add one to the first total count value after receiving the first multiplexing reply message sent by the second communication interface module.

According to the method for establishing the physical link, the first communication interface module and the second communication interface module are used for realizing the unified establishment and management of the physical link between the first electronic device and the second electronic device, and the first communication interface module and the second communication interface module are used as managers of the physical link and can acquire all information of the physical link, so that the physical link can be multiplexed when needed, waiting or reestablishing the physical link is not needed, the problem of low establishment efficiency of the physical link is solved, the efficiency of data transmission between the devices is improved, and the user experience is improved. Meanwhile, the utilization rate of the physical link is improved by multiplexing the physical link, and resources and power consumption are saved. In addition, the method manages the effective request times of the first physical link simply and conveniently by managing the first total count value, namely manages the use condition of the first physical link by the first electronic device and the second electronic device, so that when the first physical link needs to be used, whether the first physical link is established or not can be accurately known by judging whether the first total count value is 0 or not, and whether the first physical link can be multiplexed or not. And whether the first physical link is used or not and whether the first physical link needs to be disconnected can be timely and accurately obtained through the first total counting value, so that the physical link can be timely disconnected as required. In summary, the method provided by the embodiment can improve the management efficiency and accuracy of the physical link between the first electronic device and the second electronic device, thereby improving the data transmission efficiency. In addition, in the method, after the first multiplexing connection request is sent, the first total counting value is added by one, and the first total counting value is updated, so that the accuracy of the first total counting value is ensured.

In a possible implementation, the method further includes: under the condition that the first total count value is equal to 0, the first communication interface module sends a second connection request to the second communication interface module, wherein the second connection request is used for requesting to establish a first physical link with the second communication interface module; and in response to receiving the connection success information sent by the second communication interface module, the first communication interface module adds one to the first total count value, and the connection success information represents that the first physical link is successfully established.

The first total count value is equal to 0, which indicates that the number of valid requests of the first physical link by the current first electronic device and the current second electronic device is 0, indicating that the current first physical link is not established, and therefore, the first communication interface module sends a second connection request to the second communication interface module to establish the first physical link.

In the implementation mode, the successful connection information sent by the second communication interface module is received, the first connection request is indicated to be an effective connection request, the first total count value is added by one, the first total count value is updated, and the accuracy of the first total count value is ensured.

In a possible implementation, the method further includes: and in response to receiving a second multiplexing connection request sent by the second communication interface module, the first communication interface module adds one to the first total count value, and the second multiplexing connection request is used for requesting the first communication interface module to multiplex the first physical link.

Specifically, a service module in the second electronic device sends a connection request (fourth connection request) to the second communication interface module, and the second communication interface module sends the second multiplexing connection request to the first communication interface module when determining that the second total count value is greater than 0. And the second total count value is stored in the second electronic device and represents the effective request times of the first electronic device and the second electronic device to the first physical link. And the first communication interface module receives a second multiplexing connection request sent by the second communication interface module and adds one to the first total count value. Then, the first communication interface module may further send a second multiplexing reply message to the second communication interface module, and the second communication interface module adds one to the second total count value after receiving the second multiplexing reply message.

In this implementation manner, when the second electronic device multiplexes the first physical link, the first total count value is also updated, and the first total count value is incremented by one, so that the accuracy of the first total count value is further ensured, and the accuracy of the management of the first physical link is ensured.

In one possible implementation manner, in a case that the first total count value is greater than 0, the method further includes: the first communication interface module adds one to the first service count value, and the first service count value represents the number of times of effective requests of the first service module to the first physical link.

In a possible implementation, the method further includes: the first communication interface module receives a first disconnection request sent by the first service module, wherein the first disconnection request is used for indicating the first communication interface module to disconnect a first physical link; in response to the first disconnection request, the first communication interface module decrements the first total count value by one if the first traffic count value is greater than 0; and under the condition that the first total count value is reduced by one and then is equal to 0, the first communication interface module sends a second disconnection request to the second communication interface module, wherein the second disconnection request is used for requesting the second communication interface module to disconnect the first physical link.

Optionally, the first disconnection request may include one or more of service identification information of the first service module, a link identification of the first physical link, and the like. The first service count value is greater than 0, indicating that the first disconnect request is a valid disconnect request.

In one possible implementation manner, in response to the first disconnection request, in a case where the first traffic count value is greater than 0, the method further includes: the first communication interface module decrements the first traffic count value by one.

In the above several implementation manners, when the first service module requests to disconnect the physical link, it is determined that the first service count value corresponding to the first service module is greater than 0, that is, when it is determined that the first disconnection request is an effective disconnection request, the first total count value and the first service count value are respectively decremented by one. Upon determining that the first traffic count value is equal to 0, i.e., the disconnect request is an invalid disconnect request, the disconnect request is not processed. Therefore, the accuracy of the first service count value and the first total count value can be ensured, and the accuracy of physical link management is improved. In addition, in the method, the first physical link is disconnected only when the first total count value after being subtracted by one is 0, the first physical link is multiplexed to the maximum extent, and the utilization rate of the first physical link is improved. And no matter which service module initiates the establishment of the first physical link, as long as the first total count value after the subtraction is 0 when the effective disconnection request is received, the first physical link is disconnected. Therefore, the disconnection of the first physical link is not limited by the service module initiating the connection, the situation that the connection initiated by a certain service module can only be disconnected by the service module is prevented, the independence among the service modules is ensured, and the stability and the reliability of the service function of the electronic equipment are improved.

In one possible implementation manner, in response to the first disconnection request, in a case where the first total count value is less than one and greater than 0, the method further includes: and the first communication interface module sends a count-down instruction to the second communication interface module, wherein the count-down instruction is used for indicating that the second total count value is decreased by one, and the second total count value is stored in the second electronic equipment and represents the effective request times of the first electronic equipment and the second electronic equipment to the first physical link.

In the implementation manner, when the condition of disconnecting the first physical link is not met, the first communication interface module sends a count-down instruction to the second communication interface module to synchronously update the second total count value in the second electronic device, so that the accuracy of the second total count value is ensured, the second electronic device can accurately know the current effective request times for the first physical link, and can conveniently know whether the first physical link can be multiplexed or disconnected, and the accuracy of managing the first physical link is improved.

In a possible implementation manner, the first electronic device further includes a second service module, and the method further includes: the first communication interface module receives a third connection request sent by the second service module, wherein the third connection request is used for indicating the first communication interface module to establish a first physical link; responding to the third connection request, and acquiring a first total count value by the first communication interface module; and under the condition that the first total count value is greater than 0, the first communication interface module sends a first multiplexing connection request to the second communication interface module, and adds one to the first total count value and the second service count value respectively, wherein the second service count value represents the effective request times of the second service module to the first physical link.

Optionally, the third connection request may be similar to the first connection request, and the difference is that the service identification information in the third connection request is the service identification information corresponding to the second service module.

In this implementation manner, when other service modules (second service modules) except the first service module in the first electronic device initiate a connection request for the first physical link, if it is determined that the first total count value is greater than 0, that is, it is determined that the first physical link already exists, the first total count value is updated, and a second service count value corresponding to the second service module is updated. That is to say, in this implementation, in addition to the first service module being capable of multiplexing the first physical link, other service modules are also capable of multiplexing the first physical link module, and the count value is updated after multiplexing, so that the accuracy of the count value is ensured, and the accuracy of managing the first physical link is improved.

In a possible implementation manner, the second electronic device further includes a third service module and a fourth service module, and the method further includes: the first service module establishes a logical link with the third service module based on the first physical link according to the network address information of the second electronic device and the port information of the third service module; and the second service module establishes a logical link with the fourth service module based on the first physical link according to the network address information of the second electronic device and the port information of the fourth service module.

In this implementation, the first service module establishes a logical link with the third service module based on the first physical link, and the second service module establishes a logical link with the fourth service module based on the first physical link. That is to say, different service modules share a physical link, but their respective logical links are independent, so that the independence of data transmission of each service module can be ensured, when a problem occurs in a certain logical link or service port, other logical links will not be affected, other services will not be affected, and the stability of the service function of the electronic device is improved.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the embodiments herein, "/" means "or" unless otherwise specified, for example, a/B may mean a or B; "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more than two.

In the following, the terms "first", "second" and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically stated.

In order to better understand the method provided by the embodiments of the present application, the following first analyzes the technical problem to be solved by the present application.

Currently, many service scenarios of electronic devices use short-range wireless communication technology between devices, such as file transfer, screen projection, online game, and the like between devices. Short-range wireless communication technologies between devices include Wi-Fi p2p technology, bluetooth technology, and the like.

In the related art, a physical link is mainly established by an application program in an electronic device based on a wireless communication technology. Specifically, referring to fig. 1, fig. 1 is a block diagram illustrating an application program in an electronic device in the related art. As shown in fig. 1, the electronic device a includes applications A1, A2, and A3, which are capable of establishing physical links (also referred to as physical channels, physical data transmission channels, etc.) with applications B1, B2, and B3 in the electronic device B, respectively. The application programs A1, A2, A3, B1, B2, and B3 include a service module and a communication module, respectively. And the application program establishes a physical link with a communication module of the application program of the opposite terminal through a communication module of the application program.

However, in the physical link established in the above manner, since different application programs in the same electronic device cannot mutually acquire information of the physical link established by the other application program, link multiplexing cannot be achieved, and more time and/or power consumption is required in the physical link establishment phase, which results in low efficiency. Specifically, taking the establishment of a Wi-Fi p2p physical link as an example, the application scenario analysis is as follows:

referring to fig. 2, it is assumed that application A1 and application B1 are gallery a and gallery B, respectively, and application A2 and application B2 are game a and game B, respectively. In response to the photo sharing operation of the user in the gallery A, the communication module of the gallery A and the communication module of the gallery B establish a Wi-Fi p2p physical link, and the photo is transmitted based on the physical link. At this point, the user again initiates an online request in game A. Since gallery a and gallery B are occupying the Wi-Fi p2p physical link, game a and game B can only acquire the Wi-Fi p2p physical link by preempting or waiting (shown as waiting in fig. 2) in the case where electronic device a and electronic device B support only 1 Wi-Fi p2p physical link established at the same time. Through the preemption mode, the photo transmission is interrupted, the transmission efficiency of the photo is reduced, and the user experience is influenced. By waiting, more time is consumed and the efficiency is low. Under the condition that the electronic device A and the electronic device B support 2 Wi-Fi p2p physical links to be established at the same time, the game A and the game B can reestablish one Wi-Fi p2p physical link, but the reestablishment of the Wi-Fi p2p physical link also needs time consumption, the efficiency is low, and the power consumption of the electronic device is increased.

Similarly, the bluetooth physical link also has the above problem, and is not described herein.

In summary, the method for establishing a physical link in the related art has the problems of low efficiency, influence on user experience, large power consumption of the device, and the like.

For example, fig. 3 is a schematic block diagram of an example of an electronic device according to an embodiment of the present disclosure. As shown in fig. 3, in the embodiment of the present application, both the electronic device a and the electronic device B include a communication interface program (also referred to as a communication interface module), where the communication interface program in the electronic device a is referred to as a communication interface program a, and the communication interface program in the electronic device B is referred to as an interface program B. According to the method for establishing the physical link, the communication interface program A and the communication interface program B are used for realizing the unified establishment and management of the physical link between the electronic equipment A and the electronic equipment B, and the communication interface program A and the communication interface program B are used as managers of the physical link and can acquire all information of the physical link, so that the physical link can be multiplexed when needed, the physical link does not need to be waited or reestablished, the problem of low establishment efficiency of the physical link is solved, the efficiency of data transmission between equipment is improved, and the user experience is improved. Meanwhile, the utilization rate of the physical link is improved by multiplexing the physical link, and resources and power consumption are saved.

The method for establishing the physical link provided in the embodiment of the present application may be applied to an electronic device, such as a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and the like, in which an Application (APP) may be installed.

For convenience of understanding, before the method for establishing the physical link provided in the embodiments of the present application is specifically described, terms and definitions that may be involved in the method are described.

1. Business module

The service module is a module for realizing a certain service function in an application program. In the embodiment of the present application, the electronic device may include one or more application programs, and each application program may include one or more service modules, where each service module is used to implement a different service function. For example, a note module and a to-do module may be included in the memo application. In the embodiment of the application, when a service module needs to establish a physical link with other electronic devices, a connection request can be initiated to a communication interface program.

2. Efficient connection request

In the embodiment of the present application, for a connection request initiated by a certain service module, if a corresponding physical link is successfully established or a corresponding physical link is successfully multiplexed in response to the connection request, the connection request is referred to as an effective connection request.

For example, a service module a in a certain device sends a connection request X to a communication interface program, where the connection request X is used to instruct the communication interface program to establish a physical link X1, and in response to the connection request X, if the communication interface program successfully establishes the physical link X1 or successfully multiplexes the physical link X1, the connection request X is called an effective connection request, and is also called an effective connection request of the service module a to the physical link X1; if the communication interface program does not successfully establish the physical link X1 and does not successfully multiplex the physical link X1, the connection request X is called an invalid connection request, and the connection request is also called an invalid connection request of the service module a to the physical link X1.

3. Active disconnect request

In the embodiment of the application, for a certain service module, adding 1 to a corresponding service count value every time an effective connection request of the service module to a certain physical link is added, receiving a disconnection request of the service module to the physical link every time, and if the current service count value is greater than 0, determining that the disconnection request is an effective disconnection request; and if the current service count value is equal to 0, determining that the disconnection request is an invalid disconnection request.

4. Number of valid requests

The number of valid requests is obtained by counting the number of valid connection requests and the number of valid disconnection requests of a certain physical link. It will be appreciated that the number of active requests is essentially the total number of active connection requests currently being made to a physical link minus the total number of active disconnection requests made to that physical link. For example, at the current time, the total number of valid connection requests of the module a to the physical link x1 is 5, and the total number of valid connection requests of the module a to the physical link x1 is 3, so that the current number of valid requests is 2.

5. Service counter value

The service count value, also called as a service connection count value, a service connection count or a service reference (reference) value, represents the number of valid requests currently requested by a service to a physical link. Specifically, the service count value is obtained by counting the number of times of the effective connection request and the effective disconnection request of the physical link by the service module, the service count value is increased by 1 when the service module increases the effective connection request of the physical link once, and the service count value is decreased by 1 when the service module increases the effective disconnection request of the physical link once.

6. Total count value

The total count value, also referred to as a total connection count value, a total connection count or a total reference (reference) value, etc., represents the total number of valid requests for a physical link by two devices (e.g., electronic device a and electronic device B) at both ends of the physical link. Specifically, the total count value is obtained by counting the effective connection requests of each service module in the two devices at the two ends of the physical link to the physical link and the effective disconnection times of each service module in the two devices to the physical link, the total count value is increased by 1 for each increase of the effective connection request of any service module in the two devices to the physical link, and the total count value is decreased by 1 for each increase of the effective disconnection request of any service module in the two devices to the physical link.

The total count value is a dynamically changing value. In the embodiment of the present application, the initial value of the total count value is 0, that is, the total count value is a positive integer greater than or equal to 0. A total count value greater than 0 indicates that a physical link exists and that there is currently a valid connection request indicating that there may be traffic currently using or will soon be needed to use the physical link. The total count value is 0, which indicates that the physical link is not established or the physical link is disconnected.

The following embodiments of the present application will specifically explain a method for establishing a physical link provided by the embodiments of the present application by taking an electronic device having a structure shown in fig. 4 and 5 as an example, and combining the drawings and an application scenario.

In the following embodiments, the following description is continued by taking the example of establishing a physical link between the electronic device a and the electronic device B. The physical links established by the method provided in the embodiment of the present application include, but are not limited to, a Wi-Fi p2p link, a bluetooth Basic Rate (BR) link, a bluetooth Socket (Socket) link, or a bluetooth Enhanced Data Rate (EDR) link, and the like, and the following embodiments all use the Wi-Fi p2p link as an example for description, and other types of physical links are similar to this and are not described again.

In the following embodiments, an example is given in which an application A1 in an electronic device a includes a service module A1, an application A2 includes a service module A2, an application B1 in an electronic device B includes a service B1, and an application B2 includes a service B2.

In the embodiment of the application, the establishment of the physical link includes two situations of initially requesting to establish the physical link and again requesting to establish the physical link. In addition, the present application further relates to a disconnection process of a physical link, and in combination with the embodiments, taking an electronic device a and an electronic device B as examples, the following describes establishment, multiplexing, and disconnection processes of a first physical link, which is any type of physical link, respectively.

1) Initial request to establish physical link

Fig. 6 is a flowchart illustrating an example of a method for establishing a physical link according to an embodiment of the present application, where the method includes:

s101, a business module A1 of an application program A1 in the electronic device A sends a first connection request to the communication interface program A, wherein the first connection request is used for indicating the communication interface program A and the electronic device B to establish a first physical link.

First, it should be noted that, before this step is executed, the electronic device a has completed device discovery, and the service module a1 receives a connection instruction of the user. The connection instruction is used for instructing the electronic device a to establish a first physical link with the electronic device B. The connection instruction may include physical address information of the peer device, a link type, and the like. Here, the home device is an electronic device a, and the peer device is an electronic device B. The physical address information may be, for example, a Media Access Control (MAC) address or the like. The link type refers to a type of a physical link that needs to be established, for example, a Wi-Fi p2p link, a BR link, a Socket connection, or an EDR link. In the embodiment of the application, the link type is a Wi-Fi p2p link.

In response to the connection instruction of the user, the service module a1 generates a first connection request and sends the first connection request to the communication interface program a. It is understood that, during the operation of the application A1, each service module may be established with at least one process. Optionally, the service module a1 may send the first connection request to the communication interface program a through inter-process communication based on the corresponding process.

Optionally, the first connection request may include service identification information corresponding to the service module a1, physical address information of the peer device, a link type, and the like. The service identification information is used for identifying different service modules so as to distinguish the source of each first connection request. The service identifiers of the service modules in different application programs are different, and the service identifiers of different service modules in the same application program are also different. The service identification information may be, for example, a Process Identification (PID) corresponding to the service module, for example, in this embodiment, the service identification information in the first connection request is a PID of a process corresponding to the service module a 1.

S102, the communication interface program A responds to the first connection request and determines whether a total count value A corresponding to a first physical link in the electronic equipment A is 0 or not.

It is understood that one or more physical links may be established between the electronic device a and the electronic device B at the same time, and that the same type of physical link may be established multiple times. In the embodiment of the present application, each established physical link may be provided with a unique identifier (hereinafter referred to as a link identifier) to distinguish from other physical links. The form and content of the link identifier are not limited, and for example, the link identifier may include device MAC addresses of the local device and the peer device and a preset link number. Each physical link may correspond to a total count value. In this embodiment, the total count value corresponding to the first physical link stored in the electronic device a is referred to as a total count value a, or referred to as a total count value a of the electronic device a.

In this embodiment, the first physical link is initially requested to be established, so that the total count value a is 0, and step S103 is executed.

S103, the communication interface program A generates a second connection request according to the first connection request, and sends the second connection request to the communication interface program B of the electronic device B, wherein the second connection request is used for requesting to establish a first physical link with the electronic device B.

Optionally, the second connection request may include physical address information, a link identifier, and the like of the electronic device a, so that the opposite device obtains the physical address information of the local device, and distinguishes the first physical link from other physical links after the first physical link is established. In addition, the second connection request may further include other information required to establish the physical link, for example, in this embodiment, when the link type is a Wi-Fi p2p link, the second connection request may include a connection role, and the connection role may be a Group Owner (GO) or a Group Client (GC).

Optionally, the second connection request may be in a JSON (javascript object notation) format, as shown in table 1 (not including connection role and link identifier):

TABLE 1

Optionally, the communication interface program a may send the second connection request to the communication interface program B of the electronic device B based on a communication channel negotiated in advance between the electronic device a and the electronic device B according to the network address information of the peer device in the first connection request. Wherein, different types of physical links have different communication channels. It can be understood that other information or requests between the communication interface program a and the communication interface program B in this embodiment of the present application, for example, a disconnection request, a multiplexing connection request, a connection success information, a count reduction instruction, a multiplexing reply information, and the like, may be transmitted through a communication channel negotiated in advance, and details of the subsequent embodiments are not described again.

S104, the communication interface program B in the electronic equipment B responds to the second connection request and establishes a first physical link with the communication interface program B.

Specifically, the communication interface program B may determine the type of the first physical link that needs to be established according to the communication channel that receives the second connection request. In this embodiment, the link type of the first physical link is determined to be a Wi-Fi p2p link according to the communication channel receiving the second connection request. The communication interface program B establishes a first physical link with the communication interface program B based on a communication protocol (Wi-Fi p2p protocol) according to the physical address information of the electronic equipment A in the second connection request.

In some other embodiments, after the first physical link is established, device trust may be further performed. The process of device trust may be as follows: the communication interface program a sends a device credit granting request to the communication interface program B, where the device credit granting request may include user information of the electronic device a, and the user information may be, for example, account information of a preset platform logged in the device, such as account information of an X cloud platform. And the communication interface program B responds to the equipment authorization request, compares the user information of the electronic equipment A with the user information of the electronic equipment B, determines whether the user information and the user information are consistent, and passes authorization and authentication of the electronic equipment A if the user information and the user information are consistent. The safety and reliability of the first physical link between the electronic device A and the electronic device B are ensured through device credit granting.

S105, the communication interface program B adds 1 to the total count value B corresponding to the first physical link in the electronic equipment B.

The total count value B is a total count value corresponding to the first physical link stored in the electronic device B, and is also referred to as a total count value B of the electronic device B. After the communication interface program B and the communication interface program a successfully establish the first physical link, 1 may be added to the total count value B.

S106, the communication interface program B sends connection success information to the communication interface program A.

The connection success information characterizes a successful establishment of the first physical link. Optionally, the connection success information may also carry a link identifier of the first physical link, and the connection success information may also carry information of the second connection request, and the like.

S107, the communication interface program A receives the connection success information, adds 1 to the total counting value A, and adds 1 to the service counting value a1 corresponding to the service module a 1.

Optionally, after receiving the connection success information, the communication interface program a may determine, according to information of the second connection request in the connection success information, an initiating service module of the first connection request corresponding to the second connection request, and add 1 to a service count value corresponding to the service module. Specifically, the communication interface program a may establish a corresponding relationship between the second connection request and the first connection request, and when the connection success information of the second connection request is received, determine the corresponding first connection request according to the second connection request, so as to obtain the service module initiating the connection request this time, and add 1 to the service count value corresponding to the service module. In this embodiment, the service initiating module is a service module a1, a service count value corresponding to the service module a1 is referred to as a service count value a1, and 1 is added to the service count value a 1.

In this embodiment, the total count value a of the electronic device a is managed, so that the number of times of valid requests of the first physical link is managed simply and conveniently, that is, the use condition of the first physical link by the electronic device a and the electronic device B is managed, and therefore, when the first physical link needs to be used, whether the first physical link is established or not can be accurately known by judging whether the total count value a is 0 or not, and whether the first physical link can be multiplexed or not. In addition, whether the first physical link is used or not and whether the first physical link needs to be disconnected or not can be timely and accurately known through the total count value, and the physical link can be conveniently and timely disconnected when needed. In summary, the method provided by the embodiment can improve the efficiency and accuracy of managing the first physical link, and thus improve the efficiency of data transmission between the electronic device a and the electronic device B. In addition, in this embodiment, after the first physical link is successfully established, 1 is added to the service count value a1 corresponding to the service module a1 and the total count value a of the electronic device a, respectively, so as to update the count value, thereby ensuring the accuracy of the count value.

It is understood that after the first physical link is successfully established, the service module a1 may establish a logical link with the relevant service module in the electronic device B based on the first physical link, thereby forming a data transmission channel. For example, after the first physical link is successfully established, the service module a1 may establish a logical link between the service module a1 and the service module B1 based on the first physical link according to the network address information of the electronic device B and the port information of the service module B1 in the electronic device B. The network address information may be, for example, an IP address, and the port information may be, for example, a port number.

For example, fig. 7 is a schematic diagram illustrating information interaction and a change of a count value involved in initially establishing a physical link according to an embodiment of the present application. As shown in fig. 7, a service module a1 in the electronic device a transmits a first connection request to the communication interface program a. The communication interface program a determines a total count value a in response to the first connection request. As shown in fig. 7, in this embodiment, for the first time, the first physical link is requested to be established, the service count value a1 corresponding to the service module a1 is 0, the total count value a of the electronic device a is also 0, and the total count value B of the electronic device B is also 0. Thus, the communication interface program a determines that the total count value a is 0, that is, determines that the current first connection request is the initial connection request, and the communication interface program a transmits the second connection request to the communication interface program B of the electronic device B. The communication interface program B establishes a first physical link with the communication interface program a in response to the second connection request, and adds 1 to the total count value B, which changes from 0 to 1. The communication interface program B transmits connection success information to the communication interface program a, and upon receiving the connection success information, the communication interface program a adds 1 to the traffic count value a1 and 1 to the total count value a, changes the traffic count value a1 from 0 to 1, and changes the total count value a from 0 to 1.

2) Requesting again the establishment of a physical link

After establishing the first physical link according to the procedure of 1) above, the service module may also request establishment of the physical link again, i.e. initiate a connection request again. Reinitiating the connection request includes three cases: (1) the service module a1 initiates a connection request again; (2) other service modules (except the service module a 1) in the electronic equipment A initiate connection requests; (3) and a service module in the electronic equipment B initiates a connection request. The following describes three cases, respectively.

(1) The service module a1 initiates a connection request again

Exemplarily, fig. 8 is a schematic flowchart of a method for establishing another physical link according to an embodiment of the present application, where the method includes:

s201, a business module A1 of an application program A1 in the electronic device A sends a first connection request to the communication interface program A, and the first connection request is used for indicating the communication interface program A and the electronic device B to establish a first physical link.

Optionally, the first connection request is the same as the foregoing embodiment, and is not described again.

S202, the communication interface program a determines whether the total count value a of the current electronic device a is 0 in response to the first connection request.

The total count value a is greater than 0, indicating that the first physical link already exists. In this embodiment, the total count value of the electronic device a is 1, and step S203 is executed.

S203, the communication interface program a sends a first multiplexing connection request to the communication interface program B of the electronic device B, where the first multiplexing connection request is used to request the communication interface program B to multiplex a first physical link.

Optionally, the first multiplexing connection request may include physical address information of the electronic device a and a link identifier of the first physical link. The link identification facilitates the communication interface program B to know which physical link the physical link needs to be multiplexed is.

Optionally, the first multiplexing connection request may be in JSON format, as shown in table 2 (without link id):

TABLE 2

S204, the communication interface program B in the electronic equipment B responds to the first multiplexing connection request, and adds 1 to the total counting value B of the electronic equipment B.

S205, the communication interface program B sends the first reply message to the communication interface program a.

And after adding 1 to the total count value B, the communication interface program B sends first multiplexing reply information to the communication interface program A to represent that the first physical link is reusable.

S206, the communication interface program a receives the first multiplexing reply message, adds 1 to the total count value a of the electronic device a, and adds 1 to the service count value a1 corresponding to the service module a 1.

It will be appreciated that in some other embodiments, communication interface program B may not send the first multiplexed reply message to communication interface program a. The communication interface program B directly adds 1 to the total count value a and adds 1 to the traffic count value a1 after sending the first multiplex connection request to the communication interface program B.

For example, fig. 9 is a schematic diagram illustrating information interaction and count value change involved in reestablishing a physical link according to an embodiment of the present application. As shown in fig. 9, a service module a1 in the electronic device a transmits a first connection request to the communication interface program a. The communication interface program a determines a total count value a of the electronic device a in response to the first connection request. As shown in fig. 9, in this embodiment, the service count value a1 corresponding to the service module a1 is 1, the total count value a of the electronic device a is also 1, and the total count value of the electronic device B is also 1. Thus, the communication interface program a determines that the total count value a is greater than 0, that is, determines that the current connection request is a reconnection request, and the communication interface program a transmits a first multiplexed connection request to the communication interface program B of the electronic device B. The communication interface program B adds 1 to the total count value B in response to the first multiplex connection request, the total count value B changing from 1 to 2. The communication interface program B sends the first reply message to the communication interface program a, and the communication interface program a, upon receiving the first reply message, adds 1 to the traffic count value a1 and adds 1 to the total count value a, where the traffic count value a1 changes from 1 to 2 and the total count value a changes from 1 to 2.

(2) Other service modules in the electronic equipment A initiate connection requests

In this embodiment, the following embodiments shown in fig. 8 and fig. 9 are described by taking an example in which the service module A2 of the application A2 initiates a connection request to the communication interface program a.

Exemplarily, fig. 10 is a schematic flowchart of a method for establishing a physical link according to another embodiment of the present application, where the method includes:

s301, the service module A2 of the application program A2 in the electronic device a sends a third connection request to the communication interface program a, where the third connection request is used to request to instruct the communication interface program a to establish a first physical link with the electronic device B.

The third connection request is similar to the first connection request, and is different in that the service identification information in the third connection request is service identification information corresponding to the service module a2.

S302, the communication interface program a determines whether the total count value a of the current electronic device a is 0 in response to the third connection request.

In this embodiment, the total count value of the electronic device a is 2, which indicates that the first physical link exists, and step S303 is executed.

S303, the communication interface program a sends a first multiplexing connection request to the communication interface program B of the electronic device B, where the first multiplexing connection request is used to request the communication interface program B to multiplex a first physical link.

The first multiplexing connection request is the same as the above embodiment, and is not described again.

S304, the communication interface program B in the electronic equipment B responds to the first multiplexing connection request, and adds 1 to the total counting value B of the electronic equipment B.

S305, the communication interface program B sends the first reply multiplexing message to the communication interface program a.

S306, the communication interface program a receives the first multiplexing reply message, adds 1 to the total count value a of the electronic device a, and adds 1 to the service count value a2 corresponding to the service module a2.

In this embodiment, the service count value corresponding to the service module a2 is referred to as a service count value a2.

The above process is similar to the process shown in the embodiment corresponding to fig. 8, and is not described again.

For example, fig. 11 is a schematic diagram of information interaction and count value change involved in reestablishing a physical link according to another example provided in the embodiment of the present application. As shown in fig. 11, the service module a2 in the electronic device a transmits a third connection request to the communication interface program a. The communication interface program a determines the total count value a of the electronic device a in response to the third connection request. As shown in fig. 11, in this embodiment, a service count value a1 corresponding to a current service module a1 is 2, a service count value a2 corresponding to a service module a2 is 0, a total count value a of an electronic device a is 2, and a total count value B of an electronic device B is 2. Thus, the communication interface program a determines that the total count value a is greater than 0, that is, determines that the current connection request is a reconnection request, and the communication interface program a transmits a first multiplexed connection request to the communication interface program B of the electronic device B. The communication interface program B adds 1 to the total count value B in response to the first multiplex connection request, and the total count value B changes from 2 to 3. The communication interface program B sends the first reply message to the communication interface program a, and after receiving the first reply message, the communication interface program a adds 1 to the traffic count value a2 and adds 1 to the total count value a, the traffic count value a2 changes from 0 to 1, the total count value a changes from 2 to 3, and the traffic count value a1 remains 2.

In this embodiment, the total count value a is incremented by 1 after the first multiplexing reply message is received, and the total count value a is also incremented by 1 when the second multiplexing request is received. That is to say, no matter the service module in the electronic device a multiplexes the first physical link, or the service module in the electronic device B multiplexes the first physical link, the total count value a is updated, and meanwhile, the total count value B is also updated synchronously, so that the accuracy of the total count value a and the total count value B is ensured, and the accuracy of managing the first physical link is further ensured.

It should be noted that, in this embodiment, a process of multiplexing a first physical link when initiating connection with another service module in the electronic device a is described by taking the service module A2 in the application A2 as an example. In other embodiments, when other service modules different from the service module A1 in the application A1, for example, the service module a3 in the application A1, initiate a service connection request, the implementation process is the same as the above process. That is, the implementation process is the same as the above process as long as the service module different from the service module a1 is defined as another service module, regardless of whether the application is the same or not.

In addition, it is understood that after the multiplexing request for the first physical link is completed through the above process, the service module a2 may establish a logical link with two service modules in the electronic device B based on the first physical link, thereby forming a data transmission channel. For example, after the step S305 is completed, the service module a2 may establish a logical link between the service module a2 and the service module B2 based on the first physical link according to the network address information of the electronic device B and the port information of the service module B2 in the electronic device B. It should be noted that, in the foregoing embodiment, the service module a1 establishes a logical link with the service module b1 based on the first physical link, and in this embodiment, the service module a2 establishes a logical link with the service module b2 based on the first physical link. That is to say, in the embodiment of the present application, different service modules share a physical link, but respective logical links are independent, so that independence of data transmission of each service module can be ensured, when a problem occurs in a certain logical link or service port, other logical links are not affected, other services are not affected, and stability of service functions of electronic equipment is improved.

(3) Service module in electronic equipment B initiates connection request

In this embodiment, following the embodiments shown in fig. 10 and fig. 11, a service module B1 of an application program B1 in an electronic device B initiates a connection request to a communication interface program B as an example.

Exemplarily, fig. 12 is a schematic flowchart of a method for establishing a physical link according to another embodiment of the present application, where the method includes:

s401, a business module B1 of an application program B1 in the electronic device B sends a fourth connection request to the communication interface program B, and the fourth connection request is used for requesting to indicate the communication interface program B to establish a first physical link with the electronic device A.

Optionally, the fourth connection request may include physical address information and a link type of the peer device. Here, the peer device refers to the electronic device a.

S402, the communication interface program B determines whether the total count value B of the current electronic device B is 0 in response to the fourth connection request.

In this embodiment, the total count value of the electronic device B is 3, which indicates that the first physical link exists, and step S403 is executed.

S403, the communication interface program B sends a second multiplexing connection request to the communication interface program a of the electronic device a, where the second multiplexing connection request is used to request the communication interface program a to multiplex the first physical link.

The second multiplexing connection request is similar to the first multiplexing connection request, and is different in that the physical address information carried in the second multiplexing connection request is the physical address information of the electronic device B.

S404, in response to the second multiplexing connection request, the communication interface program a in the electronic device a adds 1 to the total count value a of the electronic device a and the service count value b1 corresponding to the service module b1, respectively.

S405, the communication interface program a sends the second multiplexing reply message to the communication interface program B.

S406, the communication interface program B receives the second multiplexing reply message and adds 1 to the total count value B of the electronic equipment B.

The above process is similar to the process shown in the embodiment corresponding to fig. 10, and is not described again.

For example, fig. 13 is a schematic diagram of information interaction and count value change involved in reestablishing a physical link according to another example provided in the embodiment of the present application. As shown in fig. 13, the service module B1 in the electronic device B transmits a fourth connection request to the communication interface program B. The communication interface program B determines the total count value B of the electronic device B in response to the fourth connection request. As shown in fig. 13, in this embodiment, a service count value a1 corresponding to a current service module a1 is 2, a service count value a2 corresponding to the service module a2 is 1, a total count value a of the electronic device a is 3, a total count value B of the electronic device B is 3, and a service count value B1 corresponding to the service module B1 is 0. Thus, the communication interface program B determines that the total count value B is greater than 0, that is, determines that the current connection request is a reconnection request, and the communication interface program B transmits a second multiplexed connection request to the communication interface program a of the electronic device a. The communication interface program a adds 1 to the total count value a, which changes from 3 to 4, in response to the second multiplex connection request. Then, the communication interface program a transmits the second reply multiplexing message to the communication interface program B, and the communication interface program B, upon receiving the second reply multiplexing message, adds 1 to the traffic count value B1 and adds 1 to the total count value B, whereby the traffic count value B1 changes from 0 to 1 and the total count value B changes from 3 to 4.

3) Breaking physical links

In this embodiment, following the embodiments shown in fig. 12 and fig. 13, taking the service module a1 initiating a disconnection request as an example, a process of disconnecting the first physical link is further described.

Fig. 14 is a schematic flowchart of an example of a process for disconnecting a physical link according to an embodiment of the present application, where the method includes:

s501, a business module A1 of an application program A1 in the electronic device A sends a first disconnection request to the communication interface program A, wherein the first disconnection request is used for indicating the communication interface program A to disconnect a first physical link with the electronic device B.

Optionally, the first disconnection request may include service identification information corresponding to the service module a1, physical address information of the peer device, a link identification of the first physical link, and the like.

S502, the communication interface program A responds to the first disconnection request and determines whether a service count value a1 corresponding to the current service module a1 is 0 or not; if not, go to step S503; if yes, no operation is executed.

It will be appreciated that in some cases, although some traffic modules have a traffic count value of 0, for a particular reason, the traffic module may still send a first disconnect request to the communication interface program. For example, special reasons such as: the service count value is 0 but the user still operates the first disconnection request, or the service module detects that the first physical connection still exists according to a preset flow, and so on. In this case, the first disconnection request is considered to be an invalid connection request.

Specifically, when receiving the first disconnection request, the communication interface program a determines whether the corresponding service count value a1 is 0, and if the corresponding service count value a1 is 0, it indicates that the service module a1 has not initiated the first connection request, or all the first disconnection requests corresponding to the service module a1 have been processed, it indicates that the current first disconnection request is an invalid disconnection request, and it does not subtract 1 from the service count value a1, nor subtract 1 from the total count value a, that is, it does not perform any operation. If the service count value a1 is greater than 0, it indicates that the current first disconnection request is a valid disconnection request.

And S503, subtracting 1 from the total count value A and the service count value a1 of the electronic device A respectively.

S504, the communication interface program A determines whether the total count value A obtained after subtracting 1 is 0; if yes, executing steps S505 and S506; if not, steps S507 and S508 are executed.

The total count value a after subtracting 1 is 0, which indicates that no service needs to reuse the first physical link at present, and the first physical link may be disconnected, and steps S505 and S506 are executed. The total count value a after subtracting 1 is not 0, which indicates that other services still need to use the first physical link, and only the count value needs to be updated, and the first physical link is not disconnected, and steps S507 and S508 are executed.

And S505, the communication interface program A generates a second disconnection request according to the first disconnection request, and sends the second disconnection request to the communication interface program B in the electronic equipment B.

Optionally, the second disconnection request includes physical address information of the electronic device a and a link identifier of the first physical link.

Optionally, the second disconnect request may be in JSON format, as shown in table 3 (without link id):

TABLE 3

S506, in response to the second disconnection request, the communication interface program B in the electronic device B subtracts 1 from the total count value B of the electronic device B, and disconnects the first physical link with the communication interface program a.

And S507, the communication interface program A sends a count-down instruction to the communication interface program B of the electronic equipment B, wherein the count-down instruction is used for instructing the communication interface program B to reduce the total count value B of the electronic equipment B.

And S508, the communication interface program B responds to the count-down instruction and subtracts 1 from the total count value B of the electronic equipment B.

It should be noted that, in the embodiment of the present application, the service module a1 in the electronic device a initiates the first disconnection request as an example for description, and a process of initiating the first disconnection request by other service modules (for example, the service module a 2) in the electronic device a and a process of initiating the first disconnection request by a service module (for example, the service module B1) in the electronic device B are similar to these processes, and are not described again.

The following describes information interaction and count value change related to the disconnection of a physical link in several different scenarios where the service count value and the total count value correspond to each other, respectively, with reference to the accompanying drawings.

For example, fig. 15 is a schematic diagram of information interaction and count value change involved in breaking a physical link according to an embodiment of the present application. In this embodiment, a disconnection request (referred to as a third disconnection request) is initiated by the service module a2, and when the third disconnection request is initiated, the total count value a of the electronic device a is 4, the service count value a1 is 2, the service count value a2 is 1, the total count value B of the electronic device B is 4, and the service count value B1 is 1.

As shown in fig. 15, the service module a2 in the electronic device a transmits a third disconnection request to the communication interface program a. The third disconnection request is used for instructing the communication interface program a to disconnect the first physical link, and is different from the first disconnection request in that the service identification information carried in the third disconnection instruction is different. The communication interface program a determines whether the current traffic count value a2 is 0 in response to the third disconnection request. In this embodiment, the current traffic count value a2 is 1 and is greater than 0, so the communication interface program a subtracts 1 from the total count value a and the traffic count value a2, the total count value a changes from 4 to 3, and the traffic count value a2 changes from 1 to 0. Thereafter, the communication interface program a determines whether the total count value a after subtracting 1 is 0. In this embodiment, the total count value a after subtracting 1 is 3, which is greater than 0, and therefore, the communication interface program a sends a count-down instruction to the communication interface program B of the electronic device B. The communication interface program B subtracts 1 from the total count value B in response to the down-count instruction, and the total count value B changes from 4 to 3.

For example, fig. 16 is a schematic diagram of information interaction and count value change involved in breaking a physical link according to another embodiment of the present application. This embodiment is continued with the embodiment shown in fig. 15, and is described by taking an example in which the service module a2 initiates a third disconnection request. That is, when the service module a2 initiates the third disconnection request, the total count value a of the electronic device a is 3, the service count value a1 is 2, the service count value a2 is 0, the total count value B of the electronic device B is 3, and the service count value B1 is 1.

As shown in fig. 16, the service module a2 in the electronic device a transmits a third disconnection request to the communication interface program a. The communication interface program a determines whether the current traffic count value a2 is 0 in response to the third disconnection request. In this embodiment, the current service count value a2 is 0, so the communication interface program a determines that the third disconnection request is an invalid disconnection request, and does not perform any processing.

For example, fig. 17 is a schematic diagram of information interaction and count value change involved in breaking a physical link according to another embodiment of the present application. This embodiment is described next to the embodiment shown in fig. 16, taking an example that the service module B1 in the electronic device B initiates a disconnection request (referred to as a fourth disconnection request). That is, when the service module B1 initiates the fourth disconnection request, the total count value a of the electronic device a is 3, the service count value a1 is 2, the service count value a2 is 0, the total count value B of the electronic device B is 3, and the service count value B1 is 1.

As shown in fig. 17, the service module B1 in the electronic device B transmits a fourth disconnection request to the communication interface program B. The fourth disconnect request is for instructing communication interface program B to disconnect the first physical link. The communication interface program B determines whether the total count value B is 0 in response to the fourth disconnection request. In this embodiment, the total count value B is 3 and greater than 0, so the communication interface program B subtracts 1 from the total count value B and the traffic count value B1, the total count value a changes from 3 to 2, and the traffic count value B1 changes from 1 to 0. Thereafter, the communication interface program B determines whether the total count value B after subtracting 1 is 0. In this embodiment, the total count value B after being decremented by 1 is 2, which is greater than 0, and therefore, the communication interface program B sends a count-down instruction to the communication interface program a of the electronic device a. The communication interface program B subtracts 1 from the total count value a in response to the count-down instruction, and changes the total count value a from 3 to 2.

Illustratively, fig. 18 is a schematic diagram of information interaction and count value change involved in breaking a physical link according to another example provided in the embodiment of the present application. In this embodiment, a service module a1 initiates a first disconnection request, and when the first disconnection request is initiated, a total count value a of an electronic device a is 1, a service count value a1 is 1, a service count value a2 is 0, a total count value B of an electronic device B is 1, and a service count value B1 is 0.

As shown in fig. 18, the service module a1 in the electronic device a transmits a first disconnection request to the communication interface program a. The communication interface program a determines whether the current traffic count value a1 is 0 in response to the first disconnection request. In this embodiment, the current traffic count value a1 is 1 and is greater than 0, so the communication interface program a subtracts 1 from the total count value a and the traffic count value a1, the total count value a changes from 1 to 0, and the traffic count value a1 changes from 1 to 0. Thereafter, the communication interface program a determines whether the total count value a after subtracting 1 is 0. In this embodiment, the total count value a subtracted by 1 is 0, and therefore, the communication interface program a makes a second disconnection request to the communication interface program B of the electronic device B. The communication interface program B responds to the second disconnection instruction, disconnects the first physical link, and subtracts 1 from the total count value B, and the total count value B is changed from 1 to 0.

The connection and disconnection process of the first physical link described above is generally described below with reference to fig. 19.

Exemplarily, fig. 19 is a timing diagram of establishment and disconnection of a physical link according to an embodiment of the present application, as shown in fig. 19, at a first time point t1, a service module a1 initiates a first connection request to establish the first physical link, a service count value a1 corresponding to the service module a1 is added by 1, a total count value a of an electronic device a is added by 1, and a total count value B of an electronic device B is added by 1. At this time, the traffic count value a1=1, the total count value a =1, and the total count value B =1.

At a second time point t2, the service module a2 initiates a third connection request, the first physical link is multiplexed, the service count value corresponding to the service module a2 is increased by 1, the total count value a of the electronic device a is increased by 1, and the total count value B of the electronic device B is increased by 1. At this time, the traffic count value a1=1, the traffic count value a2=1, the total count value a =2, and the total count value B =2.

At a third time point t3, the service module a1 initiates a first disconnection request, and the current service count value a1=1, so that the first disconnection request is an effective disconnection request, the service count value a1 corresponding to the service module a1 is subtracted by 1, the total count value a of the electronic device a is subtracted by 1, and the total count value B of the electronic device B is subtracted by 1. At this time, traffic count value a1=0, traffic count value a2=1, total count value a =1, and total count value B =1. However, the total count value a after subtracting 1 is greater than 0, and thus the first physical link continues to be maintained, i.e., the first physical link is not disconnected.

At a third time point t4, the service module a1 initiates a first disconnection request, and the current service count value a1=0, so that the first disconnection request is an invalid disconnection request, the count values of the service modules and the total count value are kept unchanged, and the first physical link is kept continuously. At this time, traffic count value a1=0, traffic count value a2=1, total count value a =1, and total count value B =1.

At a fifth time point t5, the service module a2 initiates a third disconnection request, and the current service count value a2=1, so that the third disconnection request is an effective disconnection request, the service count value a2 corresponding to the service module a2 is decremented by 1, the total count value a of the electronic device a is decremented by 1, and the total count value B of the electronic device B is decremented by 1. At this time, traffic count value a1=0, traffic count value a2=0, total count value a =0, and total count value B =0. Also, the total count value a after subtracting 1 is equal to 0, thus disconnecting the first physical link.

In the method provided by the embodiment of the present application, when the service module requests to disconnect the physical link, the service count value corresponding to the service module is determined. And if the current service count value is 0, determining that the current disconnection request is an invalid disconnection request, and not processing the current disconnection request. Therefore, the accuracy of the service count value and the total count value can be ensured, and the accuracy of physical link management is improved. In addition, in the method, the first physical link is disconnected only when the total count value after 1 is subtracted is 0, the first physical link is multiplexed to the maximum extent, and the utilization rate of the first physical link is improved. Furthermore, as can be seen from fig. 19, although the first physical link is established in response to the first connection request initiated by the service module a1 for the first time at the time point t1, the first physical link is finally successfully disconnected in response to the disconnection request initiated by the service module a2. That is, no matter which service module initiates the establishment of the first physical link, as long as the total count value obtained by subtracting 1 after receiving a valid disconnection request is 0, the first physical link is disconnected. Therefore, the disconnection of the first physical link is not limited by the service module initiating the connection, the situation that the connection initiated by a certain service module can only be disconnected by the service module is prevented, the independence among the service modules is ensured, and the stability and the reliability of the service function of the electronic equipment are improved.
