Step S302, matching the state information with at least one of the first conversion mode and the first data transmission mode to obtain a matching result.

And step S303, obtaining auxiliary information according to the matching result.

In an embodiment, the ue may match the state information with at least one of a transition mode (stering mode) and a data transmission mode, and it is understood that for a 5G network, the ue has an ATSSS characteristic, that is, characteristics such as Access Traffic Steering (Access Traffic), transition (Steering), and Splitting (Splitting), and according to the delivered ATSSS rule table, the ue may determine a current Steering mode and a data transmission mode.

It should be noted that, according to the specification of 3gpp TS 24.193, the current ATSSS technology supports four Steering modes, that is, four working modes, where the four Steering modes are: a hot-Standby mode (Active-Standby), when the primary access network is unavailable, the data stream is automatically switched to the Standby access network, but the two access networks do not bear the data stream at the same time; a minimum Delay mode (smallsdelay), which automatically switches the data stream to an access network with relatively small transmission Delay, but the two access networks do not carry the data stream at the same time; a Load-Balancing mode (Load-Balancing) for distributing data traffic between the two access networks according to a fixed distribution ratio; priority-based (Priority-based) mode, the data flow is carried on the access network with high Priority by default, when the congestion of the access network with high Priority is detected, a part of data flow is switched to the access network with low Priority for transmission.

It should be noted that, the user terminal determines, according to the ATSSS rule table, that is, according to the ATSSS rule, that the data stream of the service is transmitted only through the 3GPP access technology, or only through the Non-3GPP (Non-3 GPP) access technology, or is transmitted simultaneously through the 3GPP access technology and the Non-3GPP access technology, that is, split is performed through two access technologies, and data transmission is performed through the three modes, that is, three data transmission modes of the user terminal.

In the process of obtaining the auxiliary information, the embodiment of the present invention may obtain the auxiliary information according to at least one of the target transition mode, the target data transmission mode, and the status information, and it may be understood that, when the target transition mode is used as a part of the auxiliary information, the auxiliary information is sent to the network device, so that the network device may adjust the sss rule table according to the target transition mode, so that the transition mode in the updated second sss rule table conforms to the target transition mode; when the target data transmission mode is used as a part of the auxiliary information, the auxiliary information is sent to the network equipment, so that the network equipment can adjust the ATSSS rule table according to the target data transmission mode, and the data transmission mode in the updated second ATSSS rule table conforms to the target data transmission mode; when the state information is used as a part of the auxiliary information, the auxiliary information is sent to the network equipment, so that the network equipment can adjust the ATSSS rule table according to the state information, and determine any one of a conversion mode and a data transmission mode according to the state information, so that any one of the conversion mode and the data transmission mode in the updated second ATSSS rule table conforms to the target data transmission mode; or, when the target transition mode, the target data transmission mode and the status information are all part of the auxiliary information, the auxiliary information is sent to the network device, so that the network device can adjust the sss rule table according to the above-mentioned various information to select the optimal transition mode and data transmission mode, and finally obtain the required second sss rule table.

Specifically, when a radio link failure event occurs in the 5G connection of the user terminal, the auxiliary information is obtained according to the radio link failure event, and the user terminal wants to seamlessly switch to the WiFi connection at this time. Therefore, the user terminal sends the auxiliary information to the network device, where the auxiliary information carries the following new sss rule to describe the service, where a service Descriptor (Traffic Descriptor) is used to describe the related functional requirements, and is a key attribute for implementing diversification and customization of the slicing service, so as to provide different service granularities for the user, and according to the diversified service requirements:

"Traffic Descriptor:Application-1","Steering Mode:Active-Standby,Active＝non-3GPP,Standby＝3GPP"。

taking the scene mode as a red packet robbing scene as an example, when the user terminal starts the red packet robber, the user terminal enters the red packet robbing mode. The user terminal then wishes to use the lowest latency connection in order to get a faster preemption to the red envelope. Then, the user terminal sends the auxiliary information to the network device, and the following new Steering mode is carried in the auxiliary information to perform service description:

"Traffic Descriptor:Application-2","Steering Mode:Smallest delay"。

When the auxiliary information includes a target conversion mode, the network device may determine a second conversion mode according to the target conversion mode, where the second conversion mode may be the same as the target conversion mode, or may be obtained by adjusting the network device according to a specific situation of the network device on the basis of the target conversion mode; when the auxiliary information includes the target data transmission mode, the network device may determine a second data transmission mode according to the target data transmission mode, where the second data transmission mode may be consistent with the target data transmission mode, or may be adjusted based on the target data transmission mode and in combination with specific conditions of the network device itself; when the auxiliary information includes status information, the network device may determine at least one of the second transition mode and the second data transmission mode according to the status information, and specifically may determine according to specific content of the status information; or, when the auxiliary information includes the target transition mode, the target data transmission mode, and the state information, the network device may determine the second transition mode and the second data transmission mode according to the plurality of pieces of information, and the obtained second transition mode and the second data transmission mode may be consistent with the target transition mode and the target data transmission mode, or may be obtained by adjusting, by the network device, the transition information and the specific condition of the network device itself on the basis of the target transition mode and the target data transmission mode.
