Description

Data transmission method and device

The present application claims priority of chinese patent application entitled "a method for managing correspondence" filed by the chinese intellectual property office on 13.06/2018 under the application number 201810607254.8, the entire contents of which are incorporated herein by reference.

Technical Field

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

Background

A Network Slice (NS) technology is introduced into the 5th-generation (5G) system, where a network slice refers to a logical network customized according to different service requirements on a physical or virtual network infrastructure. The terminal device may establish a Protocol Data Unit (PDU) session with a corresponding network slice according to a network requirement. The third generation partnership project (3rd generation partnership project, 3GPP) defines a user routing policy (URSP) for determining PDU session selection parameters required by different Applications (APPs), such as Network slice, Data Network Name (DNN), and Session Service Continuity (SSC) mode, etc. Through URSP, the terminal equipment can determine corresponding PDU session selection parameters according to the network requirements of the APP, then establishes PDU sessions based on the determined PDU session selection parameters, and then transmits the data of the APP through the established PDU sessions.

However, at present, there is no mandatory requirement for the URSP by the operator, and the willingness of the terminal manufacturer to implement is low, so the terminal device may not support the URSP configuration. Or, if the network side device does not issue the URSP to the terminal device, the terminal device may not be able to configure the URSP. And under the condition that the terminal equipment is not configured with the URSP, the APP can not transmit data through the PDU session meeting the network requirement of the APP.

Disclosure of Invention

The application provides a data transmission method and device, which are used for solving the problem that data of an APP (application) cannot be transmitted through a PDU (protocol data unit) session meeting network requirements under the condition that a terminal device is not configured with a URSP (universal resource locator).

In a first aspect, the present application provides a data transmission method, including: the method comprises the following steps that the terminal equipment receives a parameter transmitted by an application program, wherein the parameter is a parameter which needs to be met by a connection for transmitting data of the application program, and the parameter comprises at least one of the following parameters: the network slice parameters of the network slices required by the application program, the data network parameters of the data network required by the application program and the session service continuity parameters of the session services required by the application program. And the terminal equipment determines a target connection and transmits the data of the application program through the target connection, wherein the target connection is a connection meeting the parameters. According to the embodiment of the application, the parameters corresponding to the network requirements of the application, such as network slicing parameters and the like, are configured in the application with special network requirements, so that if the URSP is not configured in the terminal device, a user can download the installation package corresponding to the application, the parameters corresponding to the network requirements required by the application are carried in the installation package corresponding to the application, and thus the terminal device can obtain the parameters corresponding to the network requirements of the application when running the application, or the application can obtain the parameters from the corresponding server, so that the terminal device can receive the parameters obtained by the application from the corresponding server when running the application. Or, the user may download the installation package corresponding to the application program, where the parameter corresponding to the network requirement required by the application program is carried in the installation package corresponding to the application program, and if the subsequent network requirement of the application program is updated, such as a required network slice is changed, the application program may obtain the updated parameter from the corresponding server, so that the updated parameter obtained from the corresponding server by the application program may be received when the application program is running. Therefore, the terminal equipment can determine the target connection according to the parameters and further transmit the data of the application program through the target connection.

In one 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; the session service continuity parameter may be a first mode, a second mode, or a third mode.

In a possible design, before the terminal device receives a parameter delivered by an application program, an installation package of the application program may be downloaded, and the parameter may be included in the installation package. In the above design, the parameter is pre-configured in the installation package of the application program, so that after the application program is installed, reporting the parameter to the processor in the terminal device is an instruction that must be executed in the process of running the application program, and therefore when the application program is started and the application program runs to the instruction, the parameter can be automatically transferred to the processor in the terminal device.

In one possible design, the parameters may be obtained by the application from a corresponding server. In the above design, the application program may obtain the parameter from the corresponding server, so that when the application program is started, the application program may transfer the parameter obtained from the server to the processor in the terminal device.

In one possible design, when the terminal device determines the target connection, it may determine whether a connection satisfying the parameter exists in the already-established connections. If the connection meeting the parameters exists, the connection meeting the parameters is taken as the target connection, the existing connection meeting the parameters may be an established connection used for transmitting data of other application programs, and the parameters corresponding to the network requirements of the other application programs are the same as or similar to the parameters corresponding to the network requirements of the current application program. And if not, establishing a new connection meeting the parameters as a target connection. In the above design, the terminal device may preferentially transmit the data of the application program through the established connection meeting the parameter, so as to avoid the problem of resource waste caused by the newly-established connection.

In a possible design, when the terminal device establishes a new connection that satisfies the parameter, a connection establishment request may be sent to a network device, where the connection establishment request includes the parameter, and the connection establishment request is used to request the network device to establish a connection that satisfies the parameter. In the above design, the terminal device may transmit the data of the application program by requesting the network device to establish a target connection meeting the parameter requirement when no connection meeting the parameter is established.

In one possible design, the terminal device may further bind the application with the target connection. By binding the application program with the target connection, the terminal device can not only continue to transmit the data of the application program through the target connection, but also transmit the data of the newly started application program with the same or similar type as the application program through the target connection when the subsequent application program with the same or similar type as the application program is started.

In a possible design, if the parameter includes a network slice parameter and the network slice parameter is a network slice type, the terminal device may further determine, according to the network slice type, a network slice name corresponding to the network slice type in the parameter. If the parameter includes a data network parameter and the data network parameter is a data network type, the terminal device may further determine a data network name or an access point name corresponding to the data network type in the parameter according to the data network type.

In a second aspect, the present application provides a data transmission method, including: the method comprises the steps that the terminal device detects that an application program in the terminal device is started, and determines parameters corresponding to the application program based on a pre-configuration strategy, wherein the pre-configuration strategy comprises a corresponding relation between an identification of the application program and the parameters, the parameters are parameters which need to be met by connection for transmitting data of the application program, and the parameters corresponding to the application program comprise at least one of the following parameters: a network slice name of a network slice required by the application, a data network name of a data network required by the application, an access point name of the data network required by the application, and a session service continuity mode of a session service required by the application. Then, the terminal device determines a target connection, and transmits the data of the application program through the target connection, wherein the target connection is a connection meeting the parameters. The embodiment of the application pre-configures the corresponding relationship between the application program and the parameter meeting the network requirement of the application program in the terminal device, such as the corresponding relationship between the identifier of the application program pre-configured and the network slice meeting the network requirement of the application program. When the application program is monitored to be started, the corresponding parameters of the application program are determined according to the pre-configured corresponding relation, the target connection meeting the parameters can be determined, and then the data of the application program is transmitted through the target connection. In the embodiment of the application, the terminal device stores the pre-configuration policy comprising the corresponding relation between the identifier of the application and the parameter in advance, so that even if the URSP is not configured, the terminal device can determine the parameter meeting the network requirement of the application according to the pre-stored pre-configuration policy, and then can establish the PDU session meeting the network requirement of the application according to the parameter to transmit the data of the application.

In one possible design, when the terminal device determines the target connection, it may determine whether a connection satisfying the parameter exists in the already-established connections. And if so, taking the connection meeting the parameters as the target connection. And if not, establishing a new connection meeting the parameters as a target connection. In the above design, the terminal device may preferentially transmit the data of the application program through the established connection meeting the parameter, so as to avoid the problem of resource waste caused by the newly-established connection.

In one possible design, the terminal device may further bind the application with the target connection. By connecting the application program with the target, the terminal device can not only continue to transmit the data of the application program through the target connection, but also transmit the data of the newly started application program with the same or similar type as the application program through the target connection when the subsequent application program with the same or similar type as the application program is started.

The apparatus has a function of implementing any of the embodiments of the first aspect or the second aspect described above. The function can be realized by hardware, and can also be realized by executing corresponding software by hardware.

The embodiment of the present application provides a data transmission method, which may be applied to a 5G (fifth generation mobile communication system) system, such as an access network using a New radio access technology (New RAT); a Cloud Radio Access Network (CRAN) and other communication systems. Alternatively, the method may be applied to future communication (for example, in 6G or other networks) and the like.

Fig. 1A illustrates a system architecture diagram applicable to the 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, and the apparatus in fig. 1A may be hardware, software divided from functions, or a combination of the two. As shown in fig. 1A, a 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). And the terminal communicates with the DN through the base station and the user plane network element. The base station is connected with the mobility management network element through an N2 interface. The user plane network element is connected with the base station through an N3 interface, the user plane network element is connected with the DN through an N6 interface, and the UPFs are connected through an N9 interface. The interface name is only an example, and the embodiment of the present application is not particularly limited thereto.

Wherein the network elements shown in fig. 1A may be network elements in a 5G architecture.

A Data Network (DN) for providing data transmission Service to users, which may be a PDN network, such as internet (internet), IP Multimedia Service (IMS), etc.

Referring to the system architecture diagram of 5G shown in fig. 1B: the mobility management network element may include an access and mobility management entity (AMF) in 5G. And the mobility management network element is responsible for the access and mobility management of the UE in the mobile network. The AMF is responsible for UE access and mobility management, NAS message routing, SMF selection and the like. The AMF may act as an intermediate network element for transmitting session management messages between the UE and the SMF. In future communications (e.g. 6G or other networks), the mobility management network element may still be an AMF network element, or have another name, and this application is not limited thereto.

And the session management network element is responsible for forwarding path management, and if a message forwarding strategy is issued to the user plane network element, the user plane network element is instructed to process and forward the message according to the message forwarding strategy. The session management network element may be a Session Management Function (SMF) in 5G, and is responsible for session management, such as session creation/modification/deletion, UPF selection, and allocation and management of user plane tunnel information. In future communications (e.g. 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 (e.g. 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 User Data Management entity may also correspond to User Data Management or unified Data Management, or UDM for short. SDM, UDM or HSS are used to help operators achieve a uniform management of all user-related data.

The network function library function (NF) is stored with information of many network elements, such as SMF information, UPF information, and AMF information. Network elements such as an AMF, an SMF, and a UPF in the network may be connected to an NRF, so that on one hand, the network element information of the network element itself may be registered in the NRF, and on the other hand, other network elements may obtain the information of the registered network element from the NRF. Other network elements (such as AMF) may obtain optional network elements by requesting NRF according to network element type, data network identification, unknown area information, etc. If a Domain Name System (DNS) server is integrated in the NRF, the corresponding selection function network element (such as AMF) may request from 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 may also be referred to as AN access node, and if the access node is in a radio access form, the access node is referred to as a Radio Access Network (RAN), as shown in fig. 1B, and provides a radio access service for a terminal. The access node may specifically be a base station device, a small base station device, a wireless access node (WiFi AP), a wireless interworking microwave access base station (WiMAX BS), and the like in a 5G network, which is not limited in this application.

In addition, the system architecture may further include an Application Function (AF), which mainly performs dynamic policy/charging control on the forwarding plane behavior. These services require dynamic policy and charging control. The AF transmits dynamic session information needed by the PCF, receives specific information of the IP connectivity access network (IP-CAN) and acknowledgements of IP-CAN bearer layer events.

The above functions may be network elements in a hardware device, software functions running on dedicated hardware, or virtualization functions instantiated on a platform (e.g., a cloud platform).

In the present application, the plurality of the present invention means two or more. "and/or" describes the association relationship of the associated objects, meaning 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. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

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

Network Slice (NS) technology is introduced into the 5G system, and a network slice refers to a logical network customized according to different service requirements on a physical or virtual network infrastructure. One network slice may satisfy one or more network functions. A Protocol Data Unit (PDU) session established between a terminal device and a Network device has attributes such as a Network slice, a Data Network Name (DNN), and a Session Service Continuity (SSC) mode. The third generation partnership project (3 GPP) defines a user routing policy (URSP) to determine the correspondence of Applications (APP) to slice, DNN and SSC modes. The URSP mainly comprises a Traffic Descriptor (Traffic Descriptor) and a routing Descriptor (Route Selection Descriptor). The Traffic Descriptor includes names or identifiers of multiple APPs, network slice Selection information corresponding to each APP in the multiple APPs included in the Route Selection Descriptor, and wildcard network slice Selection information, that is, network slice Selection information that the APP that is not included in the Traffic Descriptor can use.

Through URSP, the terminal equipment can determine corresponding PDU session selection parameters according to the network requirements of the APP, then establishes PDU sessions based on the determined PDU session selection parameters, and then transmits the data of the APP through the established PDU sessions.

However, there is currently no mandatory requirement for a URSP by the operator, so the terminal device may not support the URSP configuration. Or, if the network side device does not issue the URSP to the terminal device, the terminal device may not be able to configure the URSP. And under the condition that the terminal equipment is not configured with the URSP, the terminal equipment cannot determine the PDU session parameters meeting the network requirements of the APP, so that the PDU session meeting the network requirements of the APP cannot be established, and the data of the APP cannot be transmitted through the PDU session meeting the network requirements of the APP (hereinafter, PCU session transmission is replaced by connection, and the connection and PDU session transmission meanings can be the same).

Based on this, the present application provides a data transmission method and apparatus, so as to solve the problem that in the prior art, terminal equipment cannot transmit data of APP through a PDU session that meets network requirements without configuring a URSP. The method and the device are based on the same inventive concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.

The data transmission method provided by the present application is specifically described below with reference to the accompanying drawings. The method can be applied to terminal equipment, and at least one APP can be installed on the terminal equipment. As shown in fig. 2, the terminal device may include an application processor on which an APP, an operating system, and the like installed on the terminal device may be executed, and a modem on which a communication protocol stack of the terminal device may be executed for transceiving data.

Referring to fig. 3, a flowchart of a data transmission method provided in the present application is shown. The method comprises the following steps:

s201, a terminal device receives a parameter transmitted by an application program APP, wherein the parameter is a parameter which needs to be satisfied by the connection for transmitting the data of the APP. The APP can be an APP with special network requirements, for example, a network session is established between the APP of a certain hand game and a network slice meeting the online speed requirement of the game.

The above parameters may include, but are not limited to, at least one of the following: the network slice parameter of the network slice required by the APP, the DN parameter of the DN of the data network required by the APP, and the SSC parameter 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 can be an SSC pattern.

The SSC mode of the session service required by the APP is a first mode (also referred to as SSC mode 1), a second mode (also referred to as SSC mode 2), or a third mode (also referred to as SSC mode 3). When the terminal device establishes a PDU session with a target DN, it may first select an Internet Protocol (IP) anchor point for the PDU session. If the PDU session is in SSC model 1, the user plane IP anchor point for 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, and the network device will need to reselect a new user plane IP anchor point when establishing another PDU session. The network device instructs the terminal to release the current PDU session, which may be specifically when the terminal device moves out of the service area of the user plane functional entity UPF served by the current PDU session, or when other network policies such as load balancing are satisfied. If the PDU session is in SSC model 3, the network device will indicate 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 to replace the current PDU session, the terminal device can transfer the data stream of the original PDU session to the newly established PDU session to maintain the data continuity, and delete the original PDU session connection according to the network indication.

In a possible example, when the terminal device downloads the installation package of the APP, the installation package carries parameters that need to be satisfied by the connection for transmitting the data of the APP, that is, a developer who develops the APP can write the parameters that need to be satisfied by the connection for transmitting the data of the APP into the installation package when writing the installation package. Therefore, after the terminal equipment downloads the installation package and installs the APP, the parameter which needs to be met by the connection for transmitting the data of the APP is reported to the processor in the terminal equipment is a section of instruction which must be executed by the APP in the operation process, and therefore in the execution process after the APP is started or started, when the processor in the terminal equipment runs to the section of instruction, the APP transmits the parameter which needs to be met by the connection for transmitting the data of the APP to the processor.

For example, if the APP has a special network requirement only in a specific operation time, for example, the APP needs a special network connection service in the operation time after logging in the member account, the APP transmits parameter information indicating the special network requirement to the processor after running in the logged-in member account. Of course, the APP may also transmit the parameter information for indicating the special network requirement to the processor in time when being started, which is not limited herein, and the parameter information for indicating the special network requirement may be transmitted to the processor at any time during the starting or running process according to the type and requirement of the APP.

In another possible example, the parameter may be pre-configured in an installation package of the APP, or when the terminal device starts the APP installed thereon, the APP establishes a connection with a server providing services for the APP, and then the APP requests the server to issue the parameter, and after the APP obtains the parameter from the server, when the APP has a special network requirement, the APP transmits the parameter to the processor of the terminal device.

In another possible example, the above two examples may be combined, that is, the above parameters may be configured in the installation package of the APP in advance, and when the network requirement of the APP is updated, such as a network slice of the requirement is changed, the application program may obtain the updated parameters from the corresponding server. And when the APP has special network requirements, transmitting the updated parameters to a processor of the terminal equipment.

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 pattern, the terminal device may determine a target connection according to the parameter.

In one implementation manner, the terminal device may configure first corresponding relationship information and a second corresponding relationship, where the first corresponding relationship includes a corresponding 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 further determine a network slice name corresponding to the network slice type according to the configured first corresponding relationship information, and may determine a DNN (or an access point name) corresponding to the DN type according to the second corresponding relationship information.

In yet another implementation manner, the terminal device may configure third correspondence information, where the third correspondence includes a correspondence between a network slice type and a network slice name or DNN (or access point name). Therefore, when the network slice parameter is a network slice type and the DN parameter is a default, the terminal device may further determine a network slice name corresponding to the network slice type and a corresponding DNN (or access point name) according to the configured third correspondence information.

For example, 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 the data of the application program through the target connection.

In a possible implementation manner, the terminal device may preferentially determine whether a connection meeting the parameter exists in the connections respectively established for other APPs. And if so, directly taking the connection meeting the parameters as the target connection. Therefore, new connection can be avoided being established, on one hand, data of the APP can be transmitted more quickly, on the other hand, processing resources required by establishing the new connection can be avoided, and the purpose of saving resources is achieved. And if not, establishing a new connection meeting the parameters as a target connection.

For example, when a terminal device establishes a new connection that satisfies the parameter, 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 may subsequently bind the APP with the target connection, so that the terminal device may continue to transmit the data of the APP through the target connection, and may also transmit the data of another APP, which is newly started and has the same or similar type as the APP, through the target connection when another APP, which is subsequently started and has the same or similar type as the APP, is started.

In addition, the terminal device can also configure default parameters. Illustratively, the default parameters may include, but are not limited to, at least one of the following: default network slice name, default DNN (or access point name), default SSC mode. Therefore, when the terminal equipment starts a certain APP, if the APP has no special network requirement, the data of the APP can be transmitted through the default connection meeting the default parameters. One implementation is that the terminal device may adopt default parameters to establish a default connection when detecting an operation of a user to power on. When the follow-up terminal equipment starts the APP, if the APP has no special network requirement, the common APP can be bound with the default connection established when the terminal equipment is started, and therefore data of the common APP can be transmitted through the default connection. In another implementation, the terminal device may also set up the default connection by using the default parameters instead of starting up the APP, and when starting up the APP, if the APP has no special network requirement, the terminal device may temporarily set up the default connection by using the default parameters, and then transmit the data of the ordinary APP through the default connection.

For better understanding of the embodiment of the present application, the data transmission process is specifically described in detail below with reference to a specific application scenario by taking the APP1 with a special network requirement and the APP2 without a special network requirement as examples.

In one exemplary illustration, the parameters passed by the application to the terminal device may include a network slice type, a DN type, and an SSC pattern. The data transmission process is shown in fig. 4:

s401, when the terminal equipment is started, an application processor in the terminal equipment triggers a modem to establish a default session and configures a corresponding network card. The default session satisfies default parameters. The default parameters may be configured in the terminal device and may include a default network slice name, a default DNN, and a default SSC mode. For example, the default parameters may be as shown in table 1.

TABLE 1

Type (B)	Network slice name	DNN	SSC pattern
				Default parameters	Network slice 0	Internet DN3	SSC model 2

Thus, the default session may satisfy the default parameters shown in Table 1, i.e., the default session corresponds to a network slice of network slice 0, a data network of Internet DN3, and an SSC mode of SSC model 2.

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

S403, the APP1 is an APP with special network requirements. When the APP1 has a special network requirement (for example, at a time when the APP1 has a special network requirement during the operation process after being started or started, for example, when a member account is logged in during the operation process, for example, a member service is enabled during the operation process, etc.), the APP1 transmits a parameter that needs to be satisfied by a connection for transmitting data of the APP1 to an application processor of the terminal device, for example, the APP1 is an APP having a specific network requirement, such as a game APP, and the APP1 may transmit a parameter shown in table 2 to an application processor of the terminal device.

TABLE 2

APP	Network slicing parameters	DN parameter	SSC parameters
				APP1	Game type network slice	Default	SSC model 1

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

TABLE 3

Network slice parameter type	Network slice name	DNN
			Game type network slice	Network slice 1	Internet DN1
Video-like network slices	Network slice 2	Internet DN2
			……	……	……

Therefore, the terminal device determines, according to the third correspondence shown in table 3 and the parameter transferred by APP1, 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.

S405, the application processor of the terminal device determines whether a target session exists, wherein the target session meets a network slice corresponding to the APP1, a corresponding DNN and a corresponding SSC mode. For example, the target session may satisfy the network slice, the corresponding DNN, and the corresponding SSC pattern corresponding to the APP1 determined in step S404, 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 pattern is SSC model 1. If yes, go to step S407. If not, go to step S406.

S406, 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. Step S407 is executed.

S407, the application processor of the terminal device binds the APP1 with the target session.

S408, the application processor of the terminal device establishes a socket (socket) connection with the APP 1.

S409, the application processor of the terminal device triggers the modem of the terminal device to transmit the data of the APP1 through the target session.

After step S402 is executed, after the application processor of the terminal device stores the routing information of the default session, if the APP2 is started, the application processor of the terminal device may bind the APP2 with the default session. Thereafter, the application processor of the terminal device establishes a socket connection with the APP 2. The application processor of the terminal device then triggers the modem of the terminal device to transmit the data of APP2 over the default session.

Another exemplary illustration, the parameters passed by the application to the terminal device may include a network slice name, DN name, and SSC pattern. The data transmission process is shown in fig. 5:

s501, when the terminal equipment is started, an application processor in the terminal equipment triggers a modem to establish a default session and configures a corresponding network card. The default session satisfies default parameters. The default parameters may be configured in the terminal device and may include a default network slice name, a default DNN, and a default SSC mode. For example, the default parameters may be as shown in table 1.

S502, the terminal device stores the routing information of the default session. The routing information for the default session may include the network card, IP address, network slice, DNN, and SSC mode for the default session.

S503, the APP1 is an APP with special network requirements. When the APP1 has a special network requirement (at the time when the APP1 has a special network requirement during the operation process after being started or started, for example, when a member account is logged in during the operation process, for example, when a member service is enabled during the operation process, etc.), parameters that need to be satisfied by a connection for transmitting data of the APP1 are transferred to an application processor of the terminal device, for example, the APP1 may transfer parameters shown in table 4 to the application processor of the terminal device.

TABLE 4

APP	Network slicing parameters	DN parameter	SSC parameters
				APP1	Network slice 1	Internet DN1	SSC model 1

S504, the application processor of the terminal device determines whether a target session exists, wherein the target session meets the parameters needed to be met by the connection for transmitting the data of the APP 1. For example, the target session may satisfy the parameters shown in table 4, i.e., the target session corresponds to a network slice of network slice 1, a data network of Internet DN1, and an SSC pattern of SSC model 1. If yes, go to step S506. If not, go to step S505.

And S505, the application processor of the terminal equipment triggers a modem of the terminal equipment to establish a target session, and configures a corresponding network card. Step S506 is performed.

S506, the application processor of the terminal device binds APP1 with the target session.

And S507, the application processor of the terminal equipment establishes socket connection with the APP 1.

S508, the application processor of the terminal device triggers the modem of the terminal device to transmit the data of the APP1 through the target session.

In an embodiment, after the terminal device stores the routing information of the default session after performing step S502, if the APP2 is started, the application processor of the terminal device may bind the APP2 with the default session and establish a socket connection with the APP 2. The application processor of the terminal device then triggers the modem of the terminal device to transmit the data of APP2 over the default session.

In embodiments of the present application, an application program transfers, to an application processor of a terminal device, a parameter that needs to be satisfied by a connection for transmitting data of the application program, where the application program may obtain the parameter through one or two of the following scenarios:

scene one: the APP1 may have parameters configured in the installation package that need to be satisfied for a connection to transport the data of the application.

Scene two: the APP1 obtains from the corresponding server the parameters that need to be satisfied for the connection to transmit the data of the application. The parameters may include a network slice type, a DN type, and an SSC pattern, e.g., the parameters shown in table 2. The parameters may also include network slice name, DN name, and SSC pattern, such as the parameters shown in table 4. Therefore, during the installation process or the startup process (after installation, startup) or the operation process after startup of the APP1, the APP1 may obtain the parameters from the server corresponding to the APP1, and then when the parameters need to be transferred to the application processor of the terminal device, such as when the APP1 is started or during the operation process after startup or when the APP1 has a special network requirement during the operation process after startup, the APP1 may transfer the parameters obtained from the server to the application processor of the terminal device.

The scene one and the scene two may exist separately or simultaneously, the scene existing simultaneously, that is, the parameter is configured in advance by the installation package of the APP1, and when the network requirement of the APP1 is updated, for example, a required network slice is changed, the APP1 may obtain the updated parameter from the corresponding server.

In the embodiment of the application, parameters corresponding to network requirements of an APP with special network requirements, such as network slices and DNNs corresponding to the network requirements, are configured in the APP. Therefore, the terminal equipment can be free from configuring the URSP, and the APP can transmit the parameters corresponding to the network requirements to the processor of the terminal equipment when having special network requirements, so that the processor can determine the target connection meeting the parameters according to the parameters transmitted by the APP, and then transmit the data of the APP to the network meeting the APP network requirements through the target connection.

Referring to fig. 6, a flow chart of another data transmission method provided by the present application is shown. The method comprises the following steps:

s601, the terminal device detects that an APP in the terminal device is started. The APP can be an APP with special network requirements, for example, a certain hand game type APP needs to establish a network session with a network slice meeting the network speed requirement of the game.

In one possible example, if the APP has special network requirements during any operation time, the terminal device will treat the APP as the APP having special network requirements during the whole operation time. In another possible example, if the APP has a special network requirement only in a specific running time, for example, the APP has a special network requirement only in the running time after logging in the member account, the terminal device may use the APP as the APP having a special network requirement in the running time after logging in the member account.

S602, the terminal device determines the parameter corresponding to the APP based on a pre-configuration strategy, the pre-configuration strategy includes a corresponding relation between the identifier of the APP and the parameter, and the parameter is a parameter which needs to be satisfied by the connection for transmitting the data of the application program. The preconfigured policy may be a Network Slice Selection Policy (NSSP) for the end device.

Wherein, the parameter corresponding to the APP may include at least one of the following parameters: a network slice name of a network slice required by the APP, a DNN of a DN required by the APP, an access point name of a DN required by the APP, and an SSC mode of a session service required by the APP. There may be three SSC patterns, and for details, reference may be made to descriptions of the three SSC patterns in the data transmission method shown in fig. 2, which are not repeated herein.

S603, the terminal equipment determines a target connection and transmits the APP data through the target connection, wherein the target connection is a connection meeting the parameters.

In a possible implementation manner, the terminal device may preferentially determine whether a connection satisfying the parameter exists in the established connections. And if so, taking the existing connection meeting the parameters as the target connection. And if not, establishing a new connection meeting the parameters as a target connection. Therefore, new connection can be avoided being established, on one hand, data of the APP can be transmitted more quickly, on the other hand, processing resources required by establishing the new connection can be avoided, and the purpose of saving resources is achieved.

Further, if the target connection has been established between the terminal device and the network device, the terminal device may bind the APP with the target connection, so that the terminal device may continue to transmit the data of the APP through the target connection, and may also transmit the newly started data of other APPs of the same or similar type as the APP through the target connection when starting other APPs of the same or similar type as the APP in the subsequent.

If the terminal device needs to establish a new connection meeting the parameters as a target connection, the terminal device may send a connection establishment request to the network device, where the connection establishment request carries the parameters, and the connection establishment request is used to request the network device to establish the target connection.

The terminal device may also configure default parameters. Illustratively, the default parameters may include, but are not limited to, at least one of the following: default network slice name, default DNN (or access point name), default SSC mode.

Further, when the terminal device starts a certain APP, if the APP has no special network requirement, the data of the APP can be transmitted through the default connection that satisfies the default parameter.

Optionally, the terminal device may further establish a default connection by using default parameters when detecting a power-on operation of the user. When the terminal equipment starts the APP, if the APP has no special network requirement, the common APP can be bound with the default connection, and therefore data of the common APP can be transmitted through the default connection. Certainly, the terminal device may also not adopt the default parameters to establish the default connection when the user starts up, but when starting up an APP, if it is determined that the APP has no special network requirements, the default connection is temporarily established according to the default parameters, and then the data of the ordinary APP is transmitted through the default connection.

Scene three: the pre-configured policy may be configured in an application processor of the terminal device. The data transmission process is shown in fig. 7:

s701, when the terminal equipment is started, an application processor in the terminal equipment triggers a modem to establish a default session and configures a corresponding network card. The default session satisfies default parameters. The default parameters may be configured in the terminal device and may include a default network slice name, a default DNN, and a default SSC mode. For example, the default parameters may be as shown in table 5.

TABLE 5

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

S703, the application processor of the terminal device determines that the APP1 has special network requirements. For example, when the APP1 with a special network requirement is started, the application processor of the terminal device may determine that the APP1 has a special network requirement, or, during the operation of the APP1 with a special network requirement, the application processor of the terminal device may determine that the APP1 has a special network requirement, for example, when a member account is logged in during the operation, for example, a member service is enabled during the operation, and the like. Step S704 is performed. The specific running time of the APP1 may refer to a running time when the APP1 has a special network requirement, for example, a scene when the APP1 has a special network requirement after logging in the member account, therefore, the APP1 is the specific running time of the APP1 during logging in the member account, and the specific running time of the APP1 may refer to a time when the APP1 logs in the member account.

For example, the application processor of the terminal device may determine that APP1 starts when detecting an operation that the user triggers APP1 to start. The application processor of the terminal device may determine that APP1 enters a particular runtime upon detecting that a user triggered the APP1 to enter a particular runtime operation.

S704, the application processor of the terminal device determines a network slice corresponding to the APP1, a corresponding DNN and a corresponding SSC mode according to a pre-configured strategy. The pre-configuration policy includes a correspondence between an identifier of the APP1 and a parameter, where the parameter is a parameter that needs to be satisfied by a connection transmitting data of the APP 1. For example, the preconfigured policy may be as shown in table 6.

TABLE 6

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

S705, the application processor of the terminal device determines whether a target session exists, where the target session satisfies a network slice corresponding to the APP1, a corresponding DNN, and a corresponding SSC pattern. For example, the target session may satisfy the network slice, the corresponding DNN, and the corresponding SSC pattern determined in step S704 by APP1, 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 pattern is SSC model 1. If yes, go to 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. Step S707 is executed.

S707, the application processor of the terminal device binds the APP1 with the target session.

S708, the application processor of the terminal device establishes a socket connection with the APP 1.

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

After step S702 is executed, after the application processor of the terminal device stores the routing information of the default session, if the APP2 is started, the application processor of the terminal device may bind the APP2 with the default session, and establish a socket connection with the APP 2. The application processor of the terminal device then triggers the modem of the terminal device to transmit the data of APP2 over the default session.

In the embodiment of the application, the corresponding relation between the APP and the parameter meeting the network requirement, such as the network slice and the DNN corresponding to the network requirement, is pre-configured in the terminal device. Therefore, when the APP has special network requirements, the terminal equipment can determine the parameters corresponding to the APP according to the pre-configured corresponding relation, can determine the target connection meeting the parameters according to the parameters corresponding to the APP, and then transmits the data of the APP to the network meeting the network requirements through the target connection. The terminal device may not support URSP configuration. Or, if the network side device does not issue the URSP to the terminal device, the terminal device may not be able to configure the URSP. And under the condition that the terminal equipment is not configured with URSP, the terminal equipment can determine the parameters meeting the APP network requirements in such a way, so that the connection meeting the APP network requirements can be established, and the APP data can be transmitted through the connection meeting the APP network requirements.
