In this implementation, after receiving the connection success information sent by the second communication interface module, indicating that the first connection request is a valid connection request, the first total count value is increased by one, and the first total count value is updated to ensure the accuracy of the first total count value sex.

In a possible implementation manner, the method further includes: in response to receiving the second multiplexed 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 multiplexed connection request It is used to request the first communication interface module to multiplex the first physical link.

Specifically, a certain service module in the second electronic device sends a connection request (fourth connection request) to the second communication interface module, and when the second communication interface module determines that the second total count value is greater than 0, it sends a connection request to the first communication interface module. The module sends a second multiplexing connection request. Wherein, the second total count value is stored in the second electronic device, and represents the number of valid requests for the first physical link by the first electronic device and the second electronic device. The first communication interface module receives the second multiplexing connection request sent by the second communication interface module, and adds one to the first total count value. Afterwards, the first communication interface module may also send second multiplexing reply information 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 information.

The terms "including", "including", "having" and their variants mean "including but not limited to" unless specifically emphasized otherwise.

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

At present, short-distance wireless communication technologies between devices are used in many business scenarios of electronic devices, such as file transfer between devices, screen projection, online games, and so on. Short-distance wireless communication technologies between devices include Wi-Fi p2p technology, Bluetooth technology, etc.

In the related art, an application program in an electronic device mainly establishes a physical link based on a wireless communication technology. Specifically, refer to FIG. 1 , which is a schematic diagram of a module of an application program in an electronic device in the related art. As shown in Figure 1, electronic device A includes application programs A1, A2, and A3, and these three application programs can respectively establish physical links (also called physical channels, physical data transmission channels, etc.). The application programs A1, A2, A3, B1, B2 and B3 respectively include a business module and a communication module. The application program establishes a physical link with the communication module of the peer application program through its own communication module.

However, for the physical link established by the above method, because different application programs in the same electronic device cannot know the information of the physical link established by the other party, link multiplexing cannot be realized, and the physical link establishment stage needs to consume more resources. much time and/or power consumption, resulting in inefficiency. Specifically, taking the establishment of a Wi-Fi p2p physical link as an example, combined with the application scenario, the analysis is as follows:

Referring to FIG. 2 , it is assumed that application program A1 and application program B1 are gallery A and gallery B respectively, and application program A2 and application program B2 are game A and game B respectively. In response to the user's photo sharing operation in gallery A, the communication module of gallery A establishes a Wi-Fi p2p physical link with the communication module of gallery B, and transmits photos based on the physical link. At this time, the user initiates an online request in game A again. Since Gallery A and Gallery B are occupying the Wi-Fi p2p physical link, when electronic device A and electronic device B can only establish one Wi-Fi p2p physical link at the same time, game A and game B can only The Wi-Fi p2p physical link is obtained by preempting or waiting (shown as waiting in FIG. 2 ). The way of preemption will cause the interruption of photo transmission, reduce the efficiency of photo transmission, and affect the user experience. By waiting, it takes more time and is less efficient. In the case that electronic device A and electronic device B support the establishment of two Wi-Fi p2p physical links at the same time, game A and game B can re-establish a Wi-Fi p2p physical link, however, rebuilding the Wi-Fi p2p physical Links are also time consuming, inefficient, and lead to increased power consumption of electronic devices.

Similarly, the Bluetooth physical link also has the above-mentioned problems, which will not be repeated here.

All in all, the method for establishing a physical link in the related art has problems such as low efficiency, affecting user experience, and high power consumption of the device.

For ease of understanding, before the method for establishing a physical link provided in the embodiment of the present application is described in detail, nouns and definitions that may be involved in the method are described first.

1. Business module

A business module refers to a module that implements a certain business 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, and 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 program. In the embodiment of the present application, when the service module needs to establish a physical link with other electronic devices, it can initiate a connection request to the communication interface program.

2. Valid connection request

In this embodiment of the application, for a connection request initiated by a certain service module, if the corresponding physical link is successfully established in response to the connection request, or the corresponding physical link is successfully multiplexed, then the connection request is called a valid connection request .

For example, the service module A in a certain device sends a connection request X to the communication interface program. The connection request X is used to instruct the communication interface program to establish a physical link x1. In response to the connection request X, if the communication interface program successfully establishes the physical link x1, or the successful multiplexing of physical link x1, the connection request X is called a valid connection request, and the connection request is also called an effective connection request of business module A to physical link x1; if the communication interface program fails to establish the physical link x1, and the physical link x1 has not been reused successfully, then 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. Valid disconnect request

In the embodiment of the present application, for a certain service module, every time an effective connection request of the service module to a certain physical link is added, the corresponding service count value is increased by 1, and every time the service module receives a disconnection request of the physical link For a connection opening request, if the current service count value is greater than 0, then determine that the disconnection request is a valid disconnection request; if the current service count value is equal to 0, then determine 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 physical link. It can be understood that the number of valid requests is essentially the total number of current valid connection requests for a certain physical link minus the total number of valid disconnection requests for the physical link. For example, at the current moment, the total number of effective connection requests of module A to physical link x1 is 5 times, and the total number of valid connection requests to physical link x1 is 3 times, so the current number of effective connection requests is 2 times.

5. Business count value

The service count value, also called the service connection count value, service connection count or service reference (reference) value, etc., represents the number of valid requests of a certain service to a certain physical link. Specifically, the service count value is obtained by counting the number of effective connection requests and effective disconnection requests of the physical link by the service module. Every time the service module adds an effective connection request to the physical link, the service count value is increased by 1, Each time the service module adds an effective disconnection request to the physical link, the service count value is decremented by 1.

6. Total value

The total count value, also known as the total connection count value, total connection count or total reference (reference) value, etc., represents the connection between two devices (such as electronic device A and electronic device B) at both ends of a physical link on the physical link. The total number of valid requests. Specifically, the total count value counts the effective connection requests of each service module in the two devices at both ends of the physical link to the physical link, and the effective disconnection times of the physical link by each service module in the two devices Obtained, every time any service module in the two devices adds a valid connection request to the physical link, the total count value is increased by 1, and every time any service module in the two devices adds a valid disconnection request to the physical link , minus 1 from the total count value.

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. If the total count value is greater than 0, it indicates that the physical link exists, and there is currently a valid connection request, indicating that there may be services currently using or will soon need to use the physical link. If the total count is 0, it means that the physical link is not established or the physical link is disconnected.

The following embodiments of the present application will take the electronic device with the structure shown in FIG. 4 and FIG. 5 as an example, and describe the method for establishing a physical link provided by the embodiment of the present application in detail in combination with the drawings and application scenarios.

In addition, the embodiment of the present application also involves the disconnection process of the physical link. In the following, in combination with the embodiment, taking electronic device A and electronic device B as examples, for any type of physical link—the establishment of the first physical link, The multiplexing and disconnection processes are explained separately.

1) The initial request to establish a physical link

Fig. 6 is a schematic flowchart of a method for establishing a physical link provided by an embodiment of the present application, the method including:

S101. The service module a1 of the 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 to instruct the communication interface program A to establish a first physical link with the electronic device B.

First of all, it should be noted that before performing this step, the electronic device A has completed device discovery, and the service module a1 has received the user's connection instruction. The connection instruction is used to instruct electronic device A to establish a first physical link with electronic device B. The connection instruction may include physical address information and link type of the peer device. Here, the local device is electronic device A, and the peer device is electronic device B. The physical address information may be, for example, a media access control (media access control address, MAC) address and the like. The link type refers to the type of physical link that needs to be established, for example, Wi-Fip2p link, BR link, Socket connection, or EDR link. In this embodiment of the application, the link type is a Wi-Fi p2p link.

In response to the user's connection instruction, the service module a1 generates a first connection request, and sends the first connection request to the communication interface program A. It can be understood that, during the running of the application program A1, at least one process can be established for each business module. 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 and link type of the peer device, and the like. Wherein, the service identification information is used to identify different service modules, so as to distinguish the source of each first connection request. The business identifiers of the business modules in different application programs are different, and the service identifiers of different business modules in the same application program are also different. The service identification information may be, for example, a process identification (process identification, PID) corresponding to the service module. For example, in this embodiment, the service identification information in the first connection request is the PID of the process corresponding to the service module a1.

S102. The communication interface program A determines whether the total count value A corresponding to the first physical link in the electronic device A is 0 in response to the first connection request.

It can be understood that at the same moment, one or more physical links may be established between electronic device A and electronic device B, and the same type of physical links may also be established multiple times. In this 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 it from other physical links. The form and content of the link identifier are not limited, for example, it may include the 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 called the total count value A, or the total count value A of the electronic device A.

In this embodiment, it is the first request to establish the first physical link, therefore, 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, and the second connection request is used to request to establish a first physical link with the electronic device B .

Optionally, the second connection request may include the physical address information of the electronic device A, the link identifier, etc., so that the peer device can know the physical address information of the local device, and after the first physical link is established, the first Physical links are distinguished from other physical links. In addition, the second connection request may also include other information required to establish a physical link. For example, in this embodiment, when the link type is a Wi-Fi p2p link, the second connection request may include the connection role , the connection role can be group owner (group owner, GO) or group client (group client, GC).

Optionally, the second connection request can be in JS object notation (javascript object notation, JSON) format, as shown in Table 1 (excluding connection roles and link identifiers):

Table 1

Optionally, the communication interface program A may send the second connection request to the communication channel of electronic device B based on the network address information of the peer device in the first connection request and based on the communication channel pre-negotiated between electronic device A and electronic device B. Interface program B. Wherein, different types of physical links have different communication channels negotiated. It can be understood that other information or requests between communication interface program A and communication interface program B in the embodiment of the present application, such as disconnection request, multiplexing connection request, connection success information, count reduction instruction, multiplexing reply information, etc., Both can be transmitted through a pre-negotiated communication channel, and details will not be described in subsequent embodiments.

S104. The communication interface program B in the electronic device B establishes a first physical link with the communication interface program B in response to the second connection request.

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, it is determined that the link type of the first physical link is a Wi-Fi p2p link according to the communication channel that receives the second connection request. The communication interface program B establishes the first physical link with the communication interface B based on the communication protocol (Wi-Fi p2p protocol) according to the physical address information of the electronic device A in the second connection request.

In some other embodiments, after the first physical link is established, further device authorization may be performed. The process of device authorization can be as follows: communication interface program A sends a device authorization request to communication interface program B, and the device authorization request can include user information of electronic device A, for example, user information can be account information of a preset platform logged in the device, Such as the account information of the X cloud platform, etc. In response to the device credit request, the communication interface program B compares the user information of electronic device A with the user information of electronic device B to determine whether they are consistent. If they are consistent, the electronic device A is authenticated. The security and reliability of the first physical link between the electronic device A and the electronic device B are guaranteed through the device trust.

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

The total count value B is the total count value corresponding to the first physical link stored in the electronic device B, and is also referred to as the 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 indicates that the first physical link is established successfully. Optionally, the connection success information may carry the 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 count value A, and adds 1 to the service count value a1 corresponding to the service module a1.

Optionally, after the communication interface program A receives the connection success information, it may determine the initiating service module of the first connection request corresponding to the second connection request according to the information of the second connection request in the connection success information, and send the service module to the service module The corresponding service count value is increased by 1. Specifically, the communication interface program A may establish a corresponding relationship between the second connection request and the first connection request, and after receiving the connection success information of the second connection request, determine the corresponding first connection request according to the second connection request, so as to know The service module that initiates this connection request adds 1 to the service count value corresponding to the service module. In this embodiment, the initiating service module is the service module a1, and the service count value corresponding to the service module a1 is called the service count value a1, and 1 is added to the service count value a1.

In this embodiment, by managing the total count value A of electronic device A, the effective number of requests for the first physical link is managed simply and conveniently, that is, the use of the first physical link by electronic device A and electronic device B Management is performed so that when the first physical link needs to be used, it can be accurately known whether the first physical link has been established and whether the first physical link can be reused by judging whether the total count value A is 0. In addition, through the total count value, it can be timely and accurately known whether the first physical link is used and whether it needs to be disconnected, so that the physical link can be disconnected in time when necessary. In a word, the method provided in this embodiment can improve the management efficiency and accuracy of the first physical link, and further improve the data transmission efficiency between the electronic device A and the electronic device B. Moreover, 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, and the count value is updated to ensure the accuracy of the count value .

It can be understood that, after the first physical link is successfully established, the service module a1 may establish a logical link with a related 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 can establish 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. Logical link between b1. Wherein, the network address information may be, for example, an IP address, and the port information may be, for example, a port number.

As shown in FIG. 7 , the service module a1 in the electronic device A sends a first connection request to the communication interface program A. The communication interface program A determines the total count value A in response to the first connection request. As shown in Figure 7, this embodiment is the initial request to establish the first physical link, the service count value a1 corresponding to the service module a1 is 0, the total count value A of electronic device A is also 0, and the total count value B of electronic device B is also 0. is 0. Therefore, the communication interface program A determines that the total count value A is 0, that is, determines that the current first connection request is an initial connection request, and the communication interface program A sends the second connection request to the communication interface program B of the electronic device B. The communication interface program B establishes the 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, and the total count value B changes from 0 to 1. Moreover, the communication interface program B sends the connection success information to the communication interface program A, and after the communication interface program A receives the connection success information, it adds 1 to the business count value a1, adds 1 to the total count value A, and adds 1 to the business count value a1 by 0 becomes 1, and the total count value A changes from 0 to 1.

2) Request to establish a physical link again

After the first physical link is established according to the process of 1) above, the service module may request to establish the physical link again, that is, initiate a connection request again. Initiating the connection request again includes three situations: ①, the service module a1 initiates the connection request again; ②, other service modules in the electronic device A (service modules other than the service module a1) initiate the connection request; ③, the electronic device B The business module initiates a connection request. The three situations are described below.

S206. The communication interface program A receives the first multiplexing reply information, 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 a1.

It can be understood that, in some other embodiments, the communication interface program B may not send the first multiplexing reply information to the communication interface program A. After the communication interface program B sends the first multiplexed connection request to the communication interface program B, it directly adds 1 to the total count value A, and adds 1 to the service count value a1.

It can be understood that in some cases, although the service count value of some service modules is 0, for special reasons, the service module may still send the first disconnection 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 process, and so on. In this case, it is considered that the first disconnection request is an invalid connection request.

Specifically, when the communication interface program A receives the first disconnection request, it determines whether the corresponding service count value a1 is 0. If it is 0, it means that the service module a1 has not initiated the first connection request, or the service module a1 corresponds to All the first disconnection requests have been processed, indicating that the current first disconnection request is an invalid disconnection request, and the business count value a1 will not be decremented by 1, and the total count value A will be decremented by 1, that is, no operation will be performed . If the service count value a1 is greater than 0, it indicates that the current first disconnection request is a valid disconnection request.

The total count value A after decrementing 1 is 0, indicating that there is no service that needs to use the first physical link again, and the first physical link can be disconnected, and steps S505 and S506 are performed. The total count value A after subtracting 1 is not 0, indicating that there are other services that 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 performed.

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 device B.

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

Exemplarily, FIG. 15 is a schematic diagram of information interaction and count value changes involved in disconnection of a physical link provided by an embodiment of the present application. In this embodiment, the service module a2 initiates a disconnection request (referred to as the third disconnection request), and when the third disconnection request is initiated, the total count value A of the electronic device A is 4, and 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 an example for illustration.

As shown in FIG. 15 , the service module a2 in the electronic device A sends a third disconnection request to the communication interface program A. The third disconnection request is used to instruct communication interface program A to disconnect the first physical link. The difference from the first disconnection request is 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 business count value a2 is 1, which is greater than 0. Therefore, the communication interface program A reduces the total count value A and the business count value a2 by 1 respectively, the total count value A changes from 4 to 3, and the business count value a2 changes from 1 to is 0. After that, the communication interface program A determines whether the total count value A decremented by 1 is 0 or not. In this embodiment, the total count value A after decrementing by 1 is 3, which is greater than 0. 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 decreases the total count value B by 1 in response to the decrement count instruction, and the total count value B changes from 4 to 3.

Exemplarily, FIG. 16 is a schematic diagram of another example of information interaction and count value changes involved in disconnection of a physical link provided by the embodiment of the present application. This embodiment continues the embodiment shown in FIG. 15 , and the third disconnection request initiated by the service module a2 is taken as an example for description. 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 is 3. The value b1 is 1.

As shown in FIG. 16 , the service module a2 in the electronic device A sends 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.

Exemplarily, FIG. 17 is a schematic diagram of another example of information interaction and count value changes involved in disconnection of a physical link provided by the embodiment of the present application. This embodiment continues the embodiment shown in FIG. 16 , and the service module b1 in the electronic device B initiates a disconnection request (referred to as a fourth disconnection request) as an example for illustration. 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 is 3. The value b1 is 1.

As shown in FIG. 17 , the service module b1 in the electronic device B sends a fourth disconnection request to the communication interface program B. The fourth disconnection request is used to instruct the 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, which is greater than 0. Therefore, the communication interface program B subtracts 1 from the total count value B and the business count value b1, the total count value A changes from 3 to 2, and the business count value b1 changes from 1 to 0. After that, the communication interface program B determines whether the total count value B decremented by 1 is 0 or not. In this embodiment, the total count value B after subtracting 1 is 2, which is greater than 0. 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 decreases the total count value A by 1 in response to the decrement count instruction, and the total count value A changes from 3 to 2.

Exemplarily, FIG. 18 is a schematic diagram of another example of information interaction and count value changes involved in disconnection of a physical link provided by an embodiment of the present application. In this embodiment, the service module a1 initiates the first disconnection request, and when the first disconnection request is initiated, the total count value A of the electronic device A is 1, the service count value a1 is 1, the service count value a2 is 0, and the electronic device A The total count value B of the device B is 1, and the service count value b1 is 0 as an example for illustration.

As shown in FIG. 18 , the service module a1 in the electronic device A sends 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 service count value a1 is 1, which is greater than 0. Therefore, the communication interface program A reduces the total count value A and the service count value a1 by 1, the total count value A changes from 1 to 0, and the service count value a1 changes from 1 to 0. is 0. After that, the communication interface program A determines whether the total count value A decremented by 1 is 0 or not. In this embodiment, the total count value A after subtracting 1 is 0, therefore, the communication interface program A sends a second disconnection request to the communication interface program B of the electronic device B. The communication interface program B disconnects the first physical link in response to the second disconnection instruction, and decreases the total count value B by 1, and the total count value B changes from 1 to 0.

The process of connecting and disconnecting the above-mentioned first physical link will be described in general below with reference to FIG. 19 .

Exemplarily, FIG. 19 is a sequence diagram of the establishment and disconnection of a physical link provided by the embodiment of the present application. As shown in FIG. 19, at the first time point t1, the service module a1 initiates the first For a physical link, the service count value a1 corresponding to the service module a1 is incremented by 1, the total count value A of electronic device A is incremented by 1, and the total count value B of electronic device B is incremented by 1. At this time, the service count value a1=1, the total count value A=1, and the total count value B=1.

At the second time point t2, the service module a2 initiates the third connection request and multiplexes the first physical link, the service count value corresponding to the service module a2 increases by 1, the total count value A of electronic device A increases by 1, and the total count value of electronic device B B plus 1. At this time, the service count value a1=1, the service count value a2=1, the total count value A=2, and the total count value B=2.

At the third moment t3, the service module a1 initiates the first disconnection request, and the current service count value a1=1, so the first disconnection request is a valid disconnection request, and the service count value a1 corresponding to the service module a1 is decremented 1. The total count value A of electronic device A is decremented by 1, and the total count value B of electronic device B is decremented by 1. At this time, the service count value a1=0, the service count value a2=1, the total count value A=1, and the total count value B=1. However, the total count value A after subtracting 1 is greater than 0, so the first physical link continues to be maintained, that is, the first physical link is not disconnected.

At the third moment t4, the service module a1 initiates the first disconnection request, and the current service count value a1=0, so the first disconnection request is an invalid disconnection request, and the count value of each service module and the total count value remain unchanged. change, and the first physical link continues to be maintained. At this time, the service count value a1=0, the service count value a2=1, the total count value A=1, and the total count value B=1.

At the fifth moment t5, the service module a2 initiates the third disconnection request, and the current service count value a2=1, so the third disconnection request is a valid disconnection request, and the service count value a2 corresponding to the service module a2 is decremented 1. The total count value A of electronic device A is decremented by 1, and the total count value B of electronic device B is decremented by 1. At this time, the service count value a1=0, the service count value a2=0, the total count value A=0, and the total count value B=0. Moreover, the total count value A after subtracting 1 is equal to 0, thus disconnecting the first physical link.

In the method provided in 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 judged. If the current service count value is 0, it is determined that the current disconnection request is an invalid disconnection request, and this disconnection request is not processed. In this way, the accuracy of the service count value and total count value can be guaranteed, and the accuracy of physical link management can be improved. In addition, in this method, the first physical link is disconnected only when the total count value after subtracting 1 is 0, so as to maximize the reuse of the first physical link and improve the utilization rate of the first physical link. Moreover, it can be seen from Figure 19 that although the first physical link is established at time t1 in response to the first connection request initially initiated by the service module a1, the final first physical link is established in response to the first connection request initiated by the service module a2 The disconnect request initiated successfully disconnected. That is to say, no matter which service module initiates the establishment of the first physical link, as long as the total count value after decrementing 1 is 0 after receiving an effective disconnection request, the first physical link is disconnected. In this way, the disconnection of the first physical link does not need to be limited by the service module that initiates the connection, preventing the situation that the connection initiated by a certain service module can only be disconnected by the service module, and ensuring the connection between the service modules. Independence improves the stability and reliability of electronic equipment business functions.
