Technical field

The present application relates to the field of communication technologies, and in particular, to a data transmission method and device.

Background technique

The 5th-generation (5G) system introduces network slice (NS) technology. The network slice refers to a logical network that is customized on the physical or virtual network infrastructure according to different service requirements. The terminal device may establish a protocol data unit (PDU) session with the corresponding network slice according to the network requirements. The 3rd Generation Partnership Project (3GPP) defines a user routing selection policy (URSP), which is used to determine the PDU session selection parameters required by different applications (applications, APPs), such as Network slicing, Data Network Name (DNN), and Session Service Continuity (SSC) mode, etc. Through URSP, a terminal device can determine corresponding PDU session selection parameters according to the network requirements of the APP, then establish a PDU session based on the determined PDU session selection parameters, and then transmit data of the APP through the established PDU session.

However, at present, operators have no mandatory requirements for URSP, and terminal vendors have a lower willingness to implement, so terminal equipment may not support URSP configuration. Or, if the network-side device does not send the URSP to the terminal device, the terminal device may not be able to configure the URSP. In the case that the terminal device is not configured with URSP, the APP cannot transmit data through a PDU session that meets its own network requirements.

Summary of the Invention

The present application provides a data transmission method and device, which are used to solve the problem that in the prior art, a terminal device cannot transmit APP data through a PDU session that satisfies network requirements without configuring URP.

In a first aspect, the present application provides a data transmission method. The method includes: a terminal device receives a parameter passed by an application, the parameter is a parameter that needs to be met for a connection to transmit data of the application, and the parameter includes At least one of the following parameters: network slice parameters of the network slice required by the application, data network parameters of the data network required by the application, and session service continuity parameters of the session service required by the application. The terminal device determines a target connection, and transmits data of the application program through the target connection, and the target connection is a connection that satisfies the parameters. In the embodiment of the present application, parameters corresponding to the network requirements of the application, such as network slicing parameters, are configured in an application with special network requirements. Therefore, if URSP is not configured in the terminal device, the user can download the corresponding application program. When installing the installation package, the parameters corresponding to the network requirements required by the application are carried in the installation package corresponding to the application, so that the terminal device can obtain the parameters corresponding to the network requirements of the application when running the application. Alternatively, the application may also obtain parameters from the corresponding server, so that the terminal device may receive the parameters obtained by the application from the corresponding server when the application is run. Alternatively, the user can download the installation package corresponding to the application, and the parameters corresponding to the network requirements required by the application are carried in the installation package corresponding to the application. If the subsequent network requirements of the application are updated, such as the required network The slice has changed, etc., the application can obtain updated parameters from the corresponding server, so that when the application is run, it can receive the updated parameters obtained by the application from the corresponding server. Therefore, the terminal device can determine the target connection according to the parameter, and then transmit data of the application program through the target connection.

In a possible design, the network slice parameter may be a network slice type or a network slice name; the data network parameter may be a data network name, or a data network type or an access point name; and the session service continuity The parameter can be a first mode, a second mode, or a third mode.

After that, the terminal device determines a target connection, and transmits data of the application program through the target connection, and the target connection is a connection that satisfies the parameters. In the embodiment of the present application, the correspondence between the application and the parameters that meet its network requirements is pre-configured in the terminal device, such as the correspondence between the identifier of the pre-configured application and the network slice that meets its network requirements. Therefore, when the application is monitored to be started, parameters corresponding to the application are determined according to a pre-configured correspondence relationship, and a target connection that satisfies the parameters can be determined, and then data of the application is transmitted through the target connection.

The embodiment of the present application provides a data transmission method, which can be applied to a 5G (fifth generation mobile communication system) system, such as an access network using a new radio access technology (new radio access technology, New RAT); cloud wireless Communication system such as cloud access network (CRAN). Alternatively, it can also be applied to future communications (for example, in 6G or other networks).

FIG. 1A exemplarily illustrates a schematic diagram of a system architecture applicable to an embodiment of the present application. It should be understood that the embodiments of the present application are not limited to the system shown in FIG. 1A. In addition, the device in FIG. 1A may be hardware, functionally divided software, or a combination of the two. As shown in FIG. 1A, the system architecture provided in the embodiment of the present application includes a terminal, a base station, a mobility management network element, a session management network element, a user plane network element, and a data network (DN). The terminal communicates with the DN through the base station and the user plane network element. The base station and the mobility management network element are connected through an N2 interface. The user plane network element and the base station are connected through the N3 interface, the user plane network element and the DN can be connected through the N6 interface, and multiple UPFs are connected through the N9 interface. The interface name is only an example description, which is not specifically limited in the embodiment of the present application.

The network element shown in FIG. 1A may be a network element in a 5G architecture.

A data network (DN) provides data transmission services for users, and can be a PDN network, such as the Internet (Internet), IP Multi-media Service (IMS), and the like.

Referring to the schematic diagram of the 5G system architecture shown in FIG. 1B: The mobility management network element may include an access and mobility management function (AMF) in 5G. The mobility management network element is responsible for UE access and mobility management in the mobile network. Among them, AMF is responsible for UE access and mobility management, NAS message routing, SMF selection, etc. AMF can be used as an intermediate network element to transmit session management messages between UE and SMF. In future communications (such as 6G or other networks), the mobility management network element may still be an AMF network element or have another name, which is not limited in this application.

The session management network element is responsible for forwarding path management. For example, it sends a packet forwarding policy to the user plane network element, instructing the user plane network element to process and forward the packet according to the packet forwarding policy. The session management network element may be a session management function (SMF) in 5G, which is responsible for session management, such as session creation / modification / deletion, UPF selection, and user plane tunnel information distribution and management. In future communications (such as 6G or other networks), the session management network element may still be an SMF network element or have another name, which is not limited in this application.

The user plane network element may be a user plane function (UPF) in a 5G architecture, as shown in FIG. 1B. The UPF is responsible for message processing and forwarding. In future communications (such as 6G or other networks), the user plane network element may still be a UPF network element or have another name, which is not limited in this application.

The system architecture provided by the embodiment of the present application may further include a policy control function (PCF) or a policy charging control function (PCRF). Among them, PCF or PCRF is responsible for policy control decisions and flow-based charging control.

The system architecture may also include a subscriber data management entity (SDM), or a home subscriber server (HSS). The user data management entity English may also correspond to User Data Management or unified data management, and the abbreviation may also correspond to UDM. SDM, UDM or HSS is used to help operators achieve unified management of all user-related data.

A network function library function ((network) function (NF) repository function (NRF) stores a lot of network element information, such as SMF information, UPF information, AMF information, etc.). Network elements such as AMF, SMF, and UPF in the network may be connected to the NRF. On the one hand, it can register its own network element information with the NRF, and on the other hand, other network elements can obtain information about the registered network elements from the NRF. Other network elements (such as AMF) can obtain optional network elements by requesting NRF according to the network element type, data network identification, and unknown area information. If a domain name system (DNS) server is integrated in the NRF, the corresponding selection function network element (such as AMF) can request the NRF to obtain other network elements (such as SMF) to be selected.

As a specific implementation form of an access network (AN), a base station can also be called an access node. If it is a wireless access form, it is called a radio access network (RAN), as shown in Figure 1B. As shown, wireless access services are provided for terminals. The access node may specifically be a base station device, a small base station device, a wireless access node (WiFi AP), a wireless interoperability microwave access base station (WiMAX access base station, WiMAX base station, etc.) in a 5G network. Not limited.

Terminal, also called access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or User device, etc. FIG. 1B uses UE as an example for description. The terminal can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital processing (personal digital assistant, PDA), or a wireless communication function. Handheld devices, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, IoT terminal devices such as fire detection sensors, smart water / electric meters, factory monitoring equipment, etc.

In addition, the system architecture may also include a network application function (AF), which mainly performs dynamic policy / charging control on the behavior of the forwarding plane. These services require dynamic policy and charging control. The AF transmits the dynamic session information required by the PCF, receives specific information of the IP-Access Network (IP-CAN), and acknowledges the IP-CAN bearer layer event.

The above function may be a network element in a hardware device, or a software function running on dedicated hardware, or a virtualization function instantiated on a platform (for example, a cloud platform).

It should be noted that the multiple involved in this application means two or more. "And / or" describes the association relationship between related objects and indicates that there can be three types of relationships. For example, A and / or B can indicate that there are three cases in which A exists alone, A and B exist, and B exists alone. The character "/" generally indicates that the related objects are an "or" relationship.

At the same time, it should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present application to describe various messages, requests, network elements, these messages, requests, devices, and core network devices should not be limited to these the term. These terms are only used to distinguish messages, requests, and network elements from each other.

The 5G system introduces network slice (NS) technology. A network slice refers to a logical network that is customized based on different service requirements on a physical or virtual network infrastructure. A network slice can meet one or more network functions. The protocol data unit (PDU) session established between the terminal device and the network device has attributes such as network slice, data network name (DNN), and session service continuity (SSC) mode. . The 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) defines a user routing policy (UESP) to determine the correspondence between an application (APP) and a slice, DNN, and SSC mode. URSP mainly includes two parts: Traffic Descriptor and Route Selection Descriptor. Among them, the Traffic Descriptor includes the names or identifications of multiple APPs, etc. The Route Selection Selection Descriptor includes the network slice selection information corresponding to each APP in the multiple APPs, as well as the wild network slice selection information, that is, the The network slice selection information that the APP can use.

Through URSP, a terminal device can determine corresponding PDU session selection parameters according to the network requirements of the APP, then establish a PDU session based on the determined PDU session selection parameters, and then transmit data of the APP through the established PDU session.

However, at present, there is no mandatory requirement for the URSP by the operator, so the terminal equipment may not support the URSP configuration. Or, if the network-side device does not send the URSP to the terminal device, the terminal device may not be able to configure the URSP. In the case that the terminal device is not configured with URSP, the terminal device cannot determine the PDU session parameters that meet the network requirements of the APP, and therefore cannot establish a PDU session that meets the network requirements of the APP, and cannot pass the network requirements of the APP. PDU session transmission (hereafter PCU session transmission uses connection instead, connection and PDU session transmission can have the same meaning) data of this APP.

Based on this, the present application provides a data transmission method and device, which are used to solve the problem that terminal devices in the prior art cannot transmit APP data through a PDU session that meets network requirements without configuring URSP. Among them, the method and the device are based on the same inventive concept. Since the principle of the method and the device for solving the problem is similar, the implementation of the device and the method can be referred to each other, and duplicated details will not be repeated.

The data transmission method provided in the present application will be specifically described below with reference to the accompanying drawings. This method can be applied to a terminal device, and at least one APP can be installed on the terminal device. As shown in FIG. 2, the terminal device may include an application processor and a modem. The application processor may execute an APP and an operating system installed on the terminal device, and the modem may execute a communication protocol stack of the terminal device for sending and receiving data. .

Referring to FIG. 3, a flowchart of a data transmission method provided by the present application. The method includes:

S201. The terminal device receives a parameter passed by an application APP, and the parameter is a parameter that needs to be met for a connection transmitting data of the APP. The APP may be an APP with special network requirements, for example, a mobile game APP needs to establish a network session with a network slice that meets the game network speed requirements.

The above parameters may include, but are not limited to, at least one of the following parameters: network slice parameters of the network slice required by the APP, DN parameters of the data network DN required by the APP, and SSC parameters of the session service required by the APP. The network slice parameter may be a network slice type or a network slice name. The DN parameter may be a DNN, or a DN type or an access point name. The SSC parameter may be an SSC mode.

The SSC mode of the session service required by the APP is the first mode (also called SSC model 1), the second mode (also called SSC model 2), or the third mode (also called For SSC model3). When the terminal device establishes a PDU session with the target DN, it may first select a user-plane network protocol (IP) anchor point for the PDU session. If the PDU session is in SSC model 1, the user plane IP anchor point of the PDU session remains unchanged throughout the lifetime of the PDU session. If the PDU session is in SSC model 2, the network device will instruct the terminal to release the current PDU session and re-establish another PDU session. The network device needs to re-select a new user plane IP anchor when establishing another PDU session. The network device instructs the terminal to release the current PDU session, specifically when the terminal device moves out of the service area of the user plane function entity UPF of the current PDU session service, or when other network policies such as load balancing are met. If the PDU session is in SSC model 3, the network device will instruct the terminal that the current PDU session will be released after a certain time. Before the release, the terminal device can request to establish a new PDU session instead of the current PDU session. The terminal device can replace the data of the original PDU session. The flow is transferred to the newly established PDU session to maintain data continuity, and the original PDU session connection is deleted according to network instructions.

In a possible example, when the terminal device downloads the installation package of the APP, the parameters in the installation package that need to be met for the connection of the APP to transmit the data of the APP, that is, the developer of the APP can write the installation package, The parameters required for the connection to transmit the data of the APP are written into the installation package. In this way, after the terminal device downloads the installation package, after installing the APP, the parameters required to report the connection to transmit data of the APP to the processor in the terminal device will be a section of instructions that the APP must execute during the running process. During the APP startup or execution process after the startup, when the processor in the terminal device runs to the instruction, the APP will transmit the parameters required by the connection for transmitting the data of the APP to the processor.

For example, if the APP has special network requirements only during a specific running time, such as when a special network connection service is required during the running time after logging in to a member account, the APP will be used to indicate special network requirements after running to the logged in member account The parameter information is passed to the processor. Of course, the APP can also pass parameter information indicating special network requirements to the processor in a timely manner when it is started. This embodiment of the application is not limited here, and can be selected according to the type and requirements of the APP during the startup or running process. Time passes parameter information used to indicate special network requirements to the processor.

In another possible example, in addition to the above parameters being pre-configured in the installation package of the APP, or when the terminal device starts the APP installed on it, the APP establishes a connection with the server providing the APP, and then the The APP requests the server to issue the parameter. After the APP obtains the parameter from the server, the APP passes the parameter to the processor of the terminal device when the APP has special network requirements.

In another possible example, the above two examples can be combined, that is, the above parameters can be pre-configured in the installation package of the APP, and when the network requirements of the APP are updated, such as the required network slice is changed, etc. The application can obtain updated parameters from the corresponding server. When the APP has special network requirements, the updated parameters are passed to the processor of the terminal device.

If the network slice parameter is a network slice name, the DN parameter is a DNN or an access point name, and the SSC parameter is an SSC mode, the terminal device may determine a target connection according to the parameter.

In an implementation manner, the terminal device may be configured with first correspondence information and a second correspondence relationship, and the first correspondence relationship includes a correspondence relationship between a network slice type and a network slice name. The second correspondence information includes a correspondence between a DN type and a DNN, or the second correspondence information includes a correspondence between a DN type and an access point name. Therefore, when the network slice parameter is a network slice type and the DN parameter is a DN type, the terminal device may also determine a network slice name corresponding to the network slice type according to the configured first correspondence information, and may determine the network slice name according to the second correspondence information. Determine the DNN (or access point name) corresponding to the DN type.

In another implementation manner, the terminal device may be configured with third correspondence information, and the third correspondence relationship includes a correspondence relationship between a network slice type and a network slice name and a DNN (or an access point name). Therefore, when the network slice parameter is the network slice type and the DN parameter is the default, the terminal device may also determine the network slice name corresponding to the network slice type and the corresponding DNN (or access) according to the configured third correspondence information. Point name).

Exemplarily, the first correspondence information, the second correspondence information, and the third correspondence information may be configured on an application processor of the terminal device.

S202. The terminal device determines the target connection, and transmits data of the application program through the target connection.

In a possible implementation manner, the terminal device may preferentially determine whether there is a connection that satisfies the parameters among connections that have been established for other APPs, respectively. If it exists, the connection that satisfies the parameters is directly used as the target connection. In this way, a new connection can be avoided, on the one hand, the APP data can be transmitted more quickly, and on the other hand, the processing resources required to establish the new connection can be avoided, thereby achieving the purpose of saving resources. If it does not exist, then a new connection that satisfies the parameters is established as the target connection.

Exemplarily, when a terminal device establishes a new connection that meets the parameters, the terminal device may send a connection establishment request to a network device, where the connection establishment request is used to request the network device to establish the target connection.

Optionally, the terminal device can subsequently bind the APP to the target connection. In this way, the terminal device can not only continue to transmit the data of the APP through the target connection, but also other APPs of the same or similar type as the APP in the future. When starting, the terminal device may also transmit data of other newly launched APPs of the same or similar type through the target connection.

In addition, the terminal device can also configure default parameters. Exemplarily, the default parameter may include, but is not limited to, at least one of the following parameters: a default network slice name, a default DNN (or an access point name), and a default SSC mode. In this way, when a terminal device starts an APP, if the APP has no special network requirements, it can transmit data of the APP through a default connection that meets the default parameters. An implementation manner is that the terminal device can establish a default connection by using default parameters when detecting a user's operation of turning on the device. When the subsequent terminal device starts the APP, if the APP has no special network requirements, the ordinary APP can be bound to the default connection established at startup, so that the data of the ordinary APP can be transmitted through the default connection. Another implementation is that the terminal device may not use the default parameters to establish a default connection when the device is turned on. Instead, when starting the APP, if the APP does not have special network requirements, the terminal device may temporarily use the default parameters to establish a default connection. The default connection transmits data of the ordinary APP.

In order to better understand the embodiments of the present application, taking APP1 with special network requirements and APP2 without special network requirements as examples, the following describes the data transmission process in detail in combination with specific application scenarios.

An exemplary description, the parameters passed by the application to the terminal device may include a network slice type, a DN type, and an SSC mode. The data transmission process is shown in Figure 4:

S401. When the terminal device is powered on, the application processor in the terminal device triggers the modem to establish a default session and configures a corresponding network card. The default session meets the default parameters. The default parameter can be configured in the terminal device. The default parameter can include a default network slice name, a default DNN, and a default SSC mode. For example, the default parameters can be as shown in Table 1.

Table 1

Therefore, the default session can meet the default parameters shown in Table 1, that is, the default session corresponds to network slice 0, the corresponding data network to Internet DN3, and the corresponding SSC mode to SSC model 2.

S402. The application processor of the terminal device saves routing information of the default session. The routing information of the default session may include the network card, IP address, network slice, DNN, and SSC mode corresponding to the default session.

S403, the APP1 is an APP with special network requirements. When APP1 has special network requirements (such as when APP1 has special network requirements during startup or after startup, such as when logging in to a member account during operation, or when enabling member services during operation, etc.) APP1 passes to the application processor of the terminal device the parameters required for the connection for transmitting the data of APP1. For example, APP1 is an APP with specific network requirements, such as a game-type APP, and APP1 can send the data to the terminal device. The application processor passes the parameters shown in Table 2.

Table 2

S404: The application processor of the terminal device determines the name of the network slice corresponding to APP1 and the name of the corresponding data network according to the third correspondence information. The third correspondence relationship may be configured in the terminal device. For example, the application processor of the terminal device may be configured with third correspondence information as shown in Table 3.

In each embodiment of the present application, the application program transmits to the application processor of the terminal device the parameters that need to be satisfied for the connection of the data transmitted by the application program, and the application program can obtain the parameters through the following scenarios 1 or 2. :

Scenario 1: The installation package of APP1 may be configured with parameters that need to be satisfied in order to transmit the data of the application program.

Scenario 2: The APP1 obtains, from the corresponding server, parameters that need to be met in order to transmit the data of the application program. This parameter can include the network slice type, DN type, and SSC mode, for example, the parameters shown in Table 2. This parameter can also include the network slice name, DN name, and SSC mode, for example, the parameters shown in Table 4. Therefore, during the installation or startup of APP1 (started after being installed) or during the running process after being started, APP1 can obtain the parameters from the server corresponding to APP1, and then request the When the application processor passes the parameters, such as when APP1 is started or in the running process after being started or when the APP1 has special network requirements in the running process after being started, APP1 can obtain the parameters from the server The application processor passed to the end device.

Therefore, the terminal device does not need to be configured with URSP. When the APP has special network requirements, it can pass the parameters corresponding to the network requirements to the processor of the terminal device, so that the processor can determine the target connection that satisfies the parameters according to the parameters passed by the APP. The data of the APP is transmitted to the network that meets the network requirements of the APP through the target connection.

6 is a flowchart of another data transmission method provided by the present application. The method includes:

S601. The terminal device detects that an APP in the terminal device is started. The APP may be an APP with special network requirements, for example, a mobile game APP needs to establish a network session with a network slice that meets the game network speed requirement.

In a possible example, if the APP has special network requirements during any running time, the terminal device will treat the APP as an APP with special network requirements throughout the running period. In another possible example, if the APP has special network requirements only during a specific running time, such as when the APP has special network requirements during the running time after logging in to a member account, the terminal device will use the APP after logging in to the member account As an APP with special network requirements during the running time.

S602. The terminal device determines a parameter corresponding to the APP based on a pre-configured policy, where the pre-configured policy includes a correspondence between an identifier of the APP and a parameter, and the parameter is a parameter that needs to be met for a connection to transmit data of the application. . The pre-configured policy can select a network slice selection policy (NSSP) for the terminal device.

The parameters corresponding to the APP may include at least one of the following parameters: the network slice name of the network slice required by the APP, the DNN of the DN required by the APP, and the access point name of the DN required by the APP. SSC mode of the session service required by the APP. There can be three SSC modes. For details, refer to the description of the three SSC modes in the data transmission method shown in FIG. 2, and details are not repeated here.

S603. The terminal device determines a target connection, and transmits data of the APP through the target connection, where the target connection is a connection that satisfies the parameters.

In a possible implementation manner, the terminal device may preferentially determine whether a connection that satisfies the parameter exists in the established connections. If it exists, the existing connection that satisfies the parameters is used as the target connection. If it does not exist, a new connection that meets the parameters is established as the target connection. In this way, a new connection can be avoided, on the one hand, the APP data can be transmitted more quickly, and on the other hand, the processing resources required to establish the new connection can be avoided, thereby achieving the purpose of saving resources.

Further, if the target connection has been established between the terminal device and the network device, the terminal device can bind the APP to the target connection, so that the terminal device can not only continue to transmit the target connection through the target connection. The data of the APP can also be used when other APPs of the same or similar type of the APP are subsequently started, and the terminal device can also transmit data of newly started other APPs of the same or similar type through the target connection.

If the terminal device needs to establish a new connection that meets the parameters as a target connection, the terminal device may send a connection establishment request to the network device, the connection establishment request carries the parameter, and the connection establishment request is used for Requesting the network device to establish the target connection.

The terminal device can also configure default parameters. Exemplarily, the default parameter may include, but is not limited to, at least one of the following parameters: a default network slice name, a default DNN (or an access point name), and a default SSC mode.

Further, when a terminal device starts an APP, if the APP has no special network requirements, the APP can transmit data of the APP through a default connection that meets the default parameters.

Optionally, the terminal device may also establish a default connection by using default parameters when detecting a user's power-on operation. When the terminal device starts the APP, if the APP has no special network requirements, the ordinary APP can be bound to a default connection, so that the data of the ordinary APP can be transmitted through the default connection. Of course, the terminal device may not use the default parameters to establish a default connection when the user starts up, but when starting an APP, if it is confirmed that the APP has no special network requirements, then temporarily establish a default connection according to the default parameters, and then transmit the Data for ordinary apps.

In order to better understand the embodiments of the present application, taking APP1 with special network requirements and APP2 without special network requirements as examples, the following describes the data transmission process in detail in combination with specific application scenarios.

Scenario 3: Pre-configured policies can be configured in the application processor of the terminal device. The data transmission process is shown in Figure 7:

S701. When the terminal device is powered on, the application processor in the terminal device triggers the modem to establish a default session and configures a corresponding network card. The default session meets the default parameters. The default parameter can be configured in the terminal device. The default parameter can include a default network slice name, a default DNN, and a default SSC mode. For example, the default parameters can be as shown in Table 5.

table 5

S702: The application processor of the terminal device saves routing information of the default session. The routing information of the default session may include the network card, IP address, network slice, DNN, and SSC mode corresponding to the default session.

S703: The application processor of the terminal device determines that APP1 has a special network requirement. For example, when APP1 with special network requirements is started, the application processor of the terminal device can determine that APP1 has special network requirements, or, when APP1 with special network requirements is running, the application processor of the terminal device can determine that APP1 has special Network requirements, such as when logging in to a member account during operation, or enabling member services during operation. Step S704 is performed. Among them, the specific running time of APP1 can refer to the running time of APP1 with special network requirements, such as the scenario where APP1 has special network needs after logging in to a member account. Therefore, APP1 is the specific running time of APP1 during the login of a member account, and the specific running time of APP1 Time is coming when APP1 logs in to the member account.

Exemplarily, the application processor of the terminal device may determine that APP1 is started when detecting an operation that the user triggers APP1 to start. The application processor of the terminal device may determine that APP1 enters a specific running time when detecting an operation that the user triggers APP1 to enter a specific running time.

S704. The application processor of the terminal device determines a network slice corresponding to APP1, a corresponding DNN, and a corresponding SSC mode according to a pre-configured policy. The pre-configured policy includes a correspondence between an identifier of APP1 and a parameter, and the parameter is a parameter that needs to be met for a connection to transmit data of the APP1. For example, the pre-configured policies can be as shown in Table 6.

Table 6

Therefore, the application processor of the terminal device can determine that the network slice corresponding to APP1 is network slice 1, the corresponding DNN is Internet DN1, and the corresponding SSC mode is SSC model 1 according to the pre-configured policy.

S705: The application processor of the terminal device determines whether a target session exists, where the target session meets a network slice corresponding to APP1, a corresponding DNN, and a corresponding SSC mode. For example, the target session can satisfy the network slice, corresponding DNN, and corresponding SSC mode of APP1 determined in step S704, that is, the network slice corresponding to the target session is network slice 1, the corresponding data network is Internet DN1, and the corresponding SSC mode For SSC model1. If yes, execute step S707. If not, go to step S706.

S706: The application processor of the terminal device triggers the modem of the terminal device to establish a target session, and configures a corresponding network card. Go to step S707.

S707: The application processor of the terminal device binds APP1 to the target session.

S708: The application processor of the terminal device establishes a socket connection with APP1.

S709: The application processor of the terminal device triggers the modem of the terminal device to transmit data of APP1 through the target session.

After executing step S702, after the application processor of the terminal device saves the routing information of the default session, if APP2 is started, the application processor of the terminal device can bind APP2 to the default session, and the application processor of the terminal device establishes an Socket connection between APP2. Afterwards, the application processor of the terminal device triggers the modem of the terminal device to transmit APP2 data through the default session.

In the embodiment of the present application, the correspondence between the APP and parameters that meet its network requirements is configured in the terminal device in advance, such as the network slice corresponding to the network requirements, DNN, and so on. Therefore, when the APP has special network requirements, the terminal device can determine the parameters corresponding to the APP according to the pre-configured correspondence relationship, and can determine the target connection that satisfies the parameter according to the parameters corresponding to the APP, and then the data of the APP through the target connection Transmission to a network that meets the needs of the network. Therefore the end device may not support URSP configuration. Or, if the network-side device does not send the URSP to the terminal device, the terminal device may not be able to configure the URSP. When the terminal device is not configured with URSP, the terminal device can determine the parameters that meet the APP network requirements in this way, so that a connection that meets the APP network requirements can be established, and then the connection can be transmitted through the connection that meets the APP network requirements.
