As described in the background art, when a terminal accesses a non-3GPP network (such as a wireless fidelity (Wireless Fidelity, WIFI) network) from a 3GPP network, the services based on the network slicing technology being used by the terminal will be affected, and thus the terminal cannot be guaranteed business continuity.

In view of the above problem, an embodiment of the present application provides a service transmission method, in which a core network device first detects whether a session establishment request message from a terminal carries a network slice identifier. When detecting that the session establishment request message carries the network slice identifier, the core network device sends prompt information to the terminal for prompting the terminal to switch from the current network or not to switch to another network.

As shown in FIG. 1 , the communication system 10 includes: a terminal 11 and a core network device 12 . Wherein, the terminal 11 and the core network device 12 are in communication connection.

It should be noted that the communication system 10 shown in FIG. 1 is only an implementation provided by the embodiments of the present application. In practical applications, the core network device 12 may also be connected to multiple terminals, which is not limited in the present application.

The N3IWF equipment is mainly used to switch the terminal from the 3GPP network to the non-3GPP network. Exemplarily, the terminal transmits service data through the 5G network at the current moment. When the terminal enters the coverage of the connected WIFI network at the first moment, since the N3IWF only supports security authentication and network access, the N3IWF does not have the function of supporting network slicing required by the 5G network. Therefore, when the terminal moves from the 5G network to the coverage of the WIFI network, the services guaranteed by network slicing will be interrupted or cannot be used normally. In this case, the N3IWF device and the AMF device can control the network switching of the terminal according to the response message sent by the terminal.

The service transmission method provided by the embodiment of the present application will be described in detail below with reference to the communication system shown in FIG. 1 and the service transmission device shown in FIG. 2 (or FIG. 3 ).

FIG. 4 is a schematic flowchart of a service transmission method provided by an embodiment of the present application. As shown in FIG. 4 , the service transmission method includes the following S401-S406.

S401. A core network device receives a session establishment request message sent by a terminal.

Specifically, the terminal transmits service data through the current network at the current moment. When the terminal enters the coverage of another registered network at the first moment, the terminal sends a session establishment request message to the core network device (eg AMF device) through the access network device (eg N3IWF device). The session establishment request message is used to request the core network device to establish a network connection between the terminal and other networks. The first moment is located after the current moment.

Optionally, the session establishment request message may be a protocol data unit (protocol data unit, PDU) session message.

Optionally, when the core network device receives the PDU session message sent by the terminal, the terminal may actively send the PDU session message to the core network device when it enters the coverage of other registered networks; it may also be the core network device. Periodically send a request message to the terminal, requesting to obtain a PDU session message. When the terminal enters the coverage of other registered networks at the first moment, the terminal sends a PDU session message to the core network device in response to the request message sent by the core network device for the first time after the first moment.

S402: The core network device detects whether the session establishment request message from the terminal carries the network slice identifier.

After receiving the session establishment request message sent by the terminal, the core network device detects whether the session establishment request message from the terminal carries the network slice identifier.

Specifically, when the terminal transmits service data through the network slicing technology of the current network (for example, the network accessed by 3GPP), the public land mobile network (PLMN) will configure a slice selection auxiliary information (network slice selection) for the terminal. assistance information, NSSAI). NSSAI is a collection of single-network slice selection assistance information (S-NSSAI), and each NSSAI can contain up to 8 S-NSSAIs. In the network, S-NSSAI uniquely identifies a network slice.

Currently, there are four kinds of NSSAI used in the network, namely: the slice selection auxiliary information configured in the terminal (configured NSSAI), the requested slice selection auxiliary information (requested NSSAI), the allowed slice selection auxiliary information (allowed NSSAI) and Subscribed slice selection assistance information (subscribed NSSAI). When the terminal registers with the current network, it usually uses the S-NSSAI of the Configured NSSAI as the Requested NSSAI to initiate initial registration. During the registration process, the network slice selection function (NSSF) device obtains the Allowed NSSAI by comparing the Configured NSSAI, Subscribed NSSAI and Requested NSSAI. The registration area is valid.

Optionally, in the use of NSSAI, Allowed NSSAI takes precedence over Configured NSSAI. The terminal only uses the S-NSSAI in the Allowed NSSAI corresponding to the network slice in the frequently changing process of the serving PLMN. In this case, after the core network device (eg, AMF device) receives the session establishment request message sent by the terminal, it analyzes whether the session establishment request message contains the value of Allowed S-NSSAI. Since the NSSAI is used to identify the network slice, the core network device detects whether the session establishment request message from the terminal carries the network slice identifier. When it is detected that the session establishment request message sent by the terminal carries the network slice identifier, execute S403. When it is detected that the session establishment request message sent by the terminal does not carry the network slice identifier, perform S406.

S403. The core network device sends prompt information to the terminal.

The prompt information is used to prompt the terminal to switch from the current network to another network, or to prompt the terminal not to switch from the current network to another network.

When detecting that the session establishment request message sent by the terminal carries the network slice identifier, the core network device sends prompt information to the terminal.

Exemplarily, when it is detected that the PDU session message sent by the terminal carries the network slice identifier, the core network device sends prompt information to the terminal through the access network device (such as an N3IWF device) to prompt the terminal to switch from the current network or not to switch. for other networks. In this case, the terminal can judge whether there is currently service data based on the network slicing technology that has not been transmitted yet, and choose to switch from the current network or not to switch to another network.

S404: The core network device receives a response message corresponding to the prompt information sent by the terminal.

After receiving the prompt information sent by the core network equipment through the access network equipment (such as the N3IWF equipment), the terminal determines whether there is currently service data based on the network slicing technology that has not been transmitted yet, and according to the prompt information, through the access network equipment ( For example, the N3IWF device) sends a response message corresponding to the prompt information to the core network device.

Specifically, if the terminal determines that there is currently service data based on the network slicing technology that has not been transmitted yet, it sends a response message to the core network device indicating that the current network is not switched to another network. Correspondingly, if the terminal determines that the current service data based on the network slicing technology has been transmitted, it sends a response message indicating switching from the current network to another network to the core network device.

Optionally, when the response message sent by the terminal to the core network device is used to indicate that the current network is not switched to another network, the terminal may also add a rejection reason to the response message.

Exemplarily, after the terminal receives the prompt information sent by the core network device, the terminal determines that a game service based on the network slicing technology is currently running. In this case, in order to ensure the continuity of the service, the terminal sends a response message to the core network device indicating that it does not switch from the current network to another network, and adds the rejection reason to the response message, and the rejection reason can be that it is in progress Game business based on network slicing technology. Correspondingly, after the terminal receives the prompt information sent by the core network device, the terminal determines that no service data based on the network slicing technology is currently being transmitted. In this case, since no service data is being transmitted, there is no need to ensure service continuity, so the terminal sends a response message indicating switching from the current network to another network to the core network device.

When the core network device receives the response message sent by the terminal for indicating that the current network is not to be switched to another network, execute S405. When the core network device receives the response message sent by the terminal for indicating switching from the current network to another network, execute S406.

S405, the core network device control terminal transmits service data through the current network.

Specifically, when the core network device receives the response message sent by the terminal to indicate that the current network does not switch to another network, the terminal determines that there is currently service data based on the network slicing technology that has not been transmitted yet. In this case, in order to ensure the continuity of the service, the core network device may, according to the response message, control the terminal to continue to transmit the service data that has not been transmitted through the current network.

S406, the core network device controls the terminal to switch from the current network to another network, and transmit service data through the other network.

Optionally, after the core network device receives the session establishment request message sent by the terminal, if the core network device determines that the session establishment request message does not carry the network slice identifier, the control terminal switches from the current network to another network, and transmits the message through the other network. business data.

Specifically, if the core network device determines that the session establishment request message does not carry the network slice identifier, it means that the terminal does not transmit service data based on the network slice technology in the current network. In this case, if the terminal moves from the current network to the coverage of other networks, the core network device can control the terminal to switch from the current network to the other network, and transmit service data through the other network.

Optionally, after receiving the response message sent by the terminal, if the response message indicates switching from the current network to another network, the core network device controls the terminal to switch from the current network to the other network, and transmits service data through the other network.

Specifically, if the response message sent by the receiving terminal is used to indicate switching from the current network to another network, it means that the terminal determines that no service data based on the network slicing technology is currently being transmitted. In this case, since no service data is being transmitted, there is no need to ensure service continuity. Therefore, the core network device controls the terminal to switch from the current network to another network, and transmit service data through the other network.

It should be noted that, the specific steps for the core network equipment to control the terminal to switch from the current network to other networks, and to transmit service data through other networks, can refer to the existing network switching method for the terminal to access the WIFI network from the 5G network. This will not be repeated here.

The present application proposes to provide a service transmission method, including: a core network device first detects whether a session establishment request message from a terminal carries a network slice identifier. When detecting that the session establishment request message carries the network slice identifier, the core network device sends prompt information to the terminal for prompting the terminal to switch from the current network or not to switch to another network. Subsequently, when the response message corresponding to the prompt information sent by the receiving terminal indicates that the terminal does not switch from the current network to another network, the terminal is controlled to transmit service data through the current network.

It can be seen from the above that when the terminal switches from the current network to another network, if the core network device detects that the session establishment request message carries the network slice identifier, it will send a message to the terminal to prompt the terminal to switch from the current network or not to switch to other networks. Information about the network. In this way, if the service transmitted by the terminal through the current network has not stopped transmission, the terminal can send a response message for not switching from the current network to another network to the core network device according to the prompt information, and the core network device controls the control according to the response message. The terminal continues to transmit service data through the current network. In this case, the present application avoids the technical problem that the service of the terminal may be interrupted when the network is switched, thereby ensuring the continuity of the service of the terminal.
