Referring to fig. 2a, fig. 2a is a schematic flowchart of a data transmission method according to an embodiment of the present application, applied to the data transmission system 10 in fig. 1 a; as shown, the present data transmission method includes the following operations.

Step 201, the second terminal sends service data to the first terminal.

Correspondingly, the first terminal receives the service data from the second terminal.

The service data is associated with service identification information of the second terminal, the service identification information is used for indicating a target bearer, the target bearer is used for transmitting the service data, and the target bearer is a bearer in at least one bearer of the first terminal.

The service Type of the service data may be indicated by the service identification information, and the service Type of the service data may be 5G Enhanced Mobile Broadband (eMBB), Ultra-high Reliable Low-Latency Communication (urlcl), large-scale Machine Type Communication (mtc), or a service Type based on other customized standards, where the service Type may be indicated by the service identification information, and when the second terminal is a Mobile phone, the service Type may be according to a Type of an application providing the service data, such as a chat application.

Correspondingly, the classification rule of the network slice is associated with the service type of the service data, for example, the network slice can be classified into a mobile entertainment slice, a security monitoring slice, an office slice, and the like according to the implementation function.

Step 202, the first terminal obtains the service identification information of the second terminal.

In one possible example, the service identification information includes at least one of: the device type indication information of the second terminal and the service type identification information.

The service types of the service data supported by the second terminal may be one or more, if there is one, the second terminal and the service types are in a one-to-one correspondence relationship, at this time, the service type of the service data of the second terminal may be indirectly indicated by the device identifier indication information of the second terminal, and if there are more, the service type indication information of a more refined level is needed to directly indicate the service type of the service data currently transmitted by the second terminal.

In a specific implementation, the device type indication information and the service type identification information may be carried by service data, may also be pre-synchronized by the second terminal to the first terminal, and the like, and may also be requested by the first terminal to feed back the information in real time by the second terminal, which is not limited herein.

In this possible example, the device type indication information of the second terminal includes any one of: the media access control MAC address of the second terminal, the equipment model information of the second terminal and the Internet protocol IP address of the second terminal.

In a specific implementation, the MAC address of the second terminal may be obtained by the first terminal analyzing the service data, the device model information of the second terminal may be obtained by the first terminal using a device hypertext transfer protocol HTTP interaction packet (a request packet and a response packet), and the IP address of the second terminal may be obtained by the first terminal analyzing the service data.

In this possible example, the service type identification information includes at least one of: the service type TOS field value of the IP message of the second terminal and the service type label field value of the IP message of the second terminal.

In a specific implementation, the TOS field value of the IP packet of the second terminal is set as a field agreed by an existing protocol, and is determined according to a protocol agreement query, and the service type tag field value of the IP packet of the second terminal is a numerical value of a self-defined service type tag field, and the service type tag field may be, for example, a header field of the IP packet.

It can be seen that, in this example, the service identifier information supported by the system may be device type indication information and/or service type identifier information of the second terminal, so that the implementation manner is flexible and various, and the use diversity of the system is improved.

Step 203, the first terminal selects a target bearer adapted to the service identification information from at least one bearer.

Wherein, a single network slice may correspond to 1 or more bearers, and if there are multiple bearers, the charging and available users of each bearer may be different. And the frequency domain position and the time domain position of the target bearer are preset and are synchronous with the network side.

In one possible example, the selecting, by the first terminal, a target bearer adapted to the service identification information from at least one bearer includes: the first terminal selects a target virtual network port adapted to the service identification information from at least one virtual network port, wherein the at least one virtual network port is in one-to-one correspondence with the at least one bearer; and the first terminal determines a target bearer used by the target virtual network port.

Each bearer corresponds to 1 independent virtual network port, and the multiple bearers correspond to multiple virtual network ports.

In a specific implementation, the control rules for the plurality of virtual Network ports conform to a multiple Wide Area Network (WAN) protocol defined by a 3rd Generation Partnership Project (3 GPP) protocol.

As can be seen, in this example, the first terminal can select a target virtual network port adapted to the service identifier information from the supported virtual network ports, and then determine a target bearer used by the target virtual network port, that is, a transmission port control mechanism similar to a physical network port is implemented by the virtual network port, so that confusion of transmission port configuration is avoided, accuracy of transmission port configuration is improved, and system performance is improved.

In this possible example, the selecting, by the first terminal, a target virtual port adapted to the service identification information from at least one virtual port includes: the first terminal acquires a mapping relation set, wherein the mapping relation set comprises a corresponding relation between service identification information and a virtual network port; and the first terminal queries the mapping relation set by taking the service identification information as a query identification to acquire a target virtual network port corresponding to the service identification information.

The mapping relationship set may be stored in the first terminal in a form of a routing table as shown in table 1, where in table 1, the service identification information includes three types of mobile entertainment, security monitoring, and office, the mobile entertainment corresponds to the virtual portal WAN1, the security monitoring corresponds to the virtual portal WAN2, and the office corresponds to the virtual portal WAN 3.

TABLE 1

Service identification information	Virtual network port
		Mobile entertainment	WAN_1
Security monitoring	WAN_2
		Working in office	WAN_3

Therefore, in this example, the first terminal can quickly determine the target virtual network port adapted to the service identification information of the second terminal in a table look-up manner, which is convenient and quick, and improves system performance.

And step 204, the first terminal transmits the service data through the target bearer.

Correspondingly, the network device receives the service data sent by the first terminal through the target bearer.

The service data is associated with service identification information of a second terminal, the service identification information is used for indicating the target bearer, and the target bearer is a bearer in at least one bearer of the first terminal.

In one possible example, before the first terminal receives the traffic data from the second terminal, the method further includes: the first terminal sends a network slice account opening request to network equipment, wherein the network slice account opening request is used for indicating a network slice account opening response, and the network slice account opening response comprises an access point name and slice service information of at least one network slice configured for the first terminal; the first terminal receives the network slice account opening response; the first terminal creates the at least one bearer corresponding to the at least one network slice according to the access point name and the slice service information of the at least one network slice.

Corresponding to this example, the method further comprises: the network equipment receives a network slice account opening request from the first terminal; the network device generates and sends a network slice account opening response to the first terminal, wherein the network slice account opening response comprises an access point name and slice service information of at least one network slice configured for the first terminal, and the network slice account opening response is used for indicating the at least one bearer corresponding to the at least one network slice.

The access point name may include, for example, an access point name APN in a fourth generation 4G wireless communication system, or a data network name DNN in a fifth generation 5G wireless communication system. A single access point may correspond to 1 or more network slices, and if the access point is a plurality of network slices, secondary offloading may be performed by corresponding network devices.

Wherein the slicing service information includes at least one of: the method comprises the steps of obtaining the QoS grade of the current network slice, the recommended service of the current network slice, the IP rule of the current network slice, the flow grade of the current network slice and the service identification information supported by the current network slice.

In a specific implementation, a specific process of the first terminal establishing the corresponding bearer according to the access point name and the slice service information of each network slice may be: the first terminal initiates a bearing establishment request to the network equipment, the request carries the access point name and the slice service information, the network equipment confirms that the transmission resource meeting the requirement can be configured according to the access point name and the slice service information, a bearing establishment response is sent, and information such as IP (Internet protocol) related to the configured bearing is sent to the first terminal.

In this example, the first terminal can interact with the network device to account for network slice management accounts, so as to implement configuration of network slice resources, and facilitate subsequent distribution of service data of the second terminal to different network slices.

In this possible example, the method further comprises: the first terminal establishes at least one corresponding virtual network port for the at least one bearer; and the first terminal stores the corresponding relation between the at least one bearer and the at least one virtual network port in a mapping relation set.

Each bearer corresponds to a virtual network port, the virtual network port is used for corresponding to the service identification information in the routing table, and the routing table is used for the first terminal to inquire the bearer corresponding to the service data, namely the mapping relation set.

As can be seen, in this example, after the first terminal establishes the bearers corresponding to the network slice, the first terminal establishes a corresponding virtual network port for each bearer, and stores the correspondence between the bearers and the virtual network ports for query in the subsequent service data routing mechanism.

It can be seen that, in the embodiment of the present application, the first terminal receives service data from the second terminal, the first terminal obtains the service identification information of the second terminal, the first terminal selects a target bearer adapted to the service identification information from the at least one bearer, and the first terminal transmits the service data through the target bearer. Therefore, for a communication system in which a terminal side transmits service data of a second terminal to a first terminal, the first terminal can perform a bearing application based on service identification information of the second terminal, thereby realizing accurate configuration of transmission resources and facilitating improvement of system performance.

The embodiments of the present application will be described with reference to specific application examples.
