[0155] In some embodiments, User Route Selection Policy (URSP) rules are used by 5G networks to provide UE route selection policies to UEs. UEs use URSP rules to match data flows to Protocol Data Unit (PDU) sessions. Each URSP rule contains a traffic descriptor (containing one or more components described in Table 1). The traffic descriptor is used to match application traffic. In addition, each URSP rule contains a list of route selection descriptors. A route selection descriptor contains one or more components, such as,

[0156] - Session and Service Continuity (SSC) mode: indicates that the traffic of the matching application should be routed via a PDU session that supports SSC mode.

[0157] - Data Network Name (DNN) selection: indicates that the traffic of the matching application should be routed via a PDU session that supports the DNN.

[0158] - Access type preference: indicates that the PDU session should be established via the corresponding access type when the UE needs to establish the corresponding PDU session at the time of URSP rule application.

[0159] - Location criteria: the route selection descriptor is not considered valid unless the location of the UE matches the value.

[0160] - and so on.

[0161] Table 1, UE Route Selection Policy Rule

[0162] In some embodiments, UEs accessing 5G networks should support URSP rules and use URSP rules to determine the PDU session to be applied to specific application traffic.

[0163] In some embodiments, considering the migration from 5G to 6G, there can be areas with insufficient 6G network coverage in the early stages of 6G deployment. In order to improve the user experience in such areas, it is necessary to consider the co-deployment of 5G and 6G networks so that UEs can simultaneously connect to 5G and 6G networks in such areas. If a UE is located in an area covered by 6G, it can connect to the 6G network. If the UE is located in an area covered by both 5G and 6G networks, it can simultaneously access and use both networks.

[0164] In some embodiments, in order to enable the UE to support 5G access and 6G access at the same time, and control traffic to use 5G network or 6G network, the control traffic can be switched or offloaded between 5G network and 6G network, and the 6G network should also support the URSP rule.

[0165] In some embodiments, in order to support 5G network and 6G network interworking, that is, the UE supports 5G network access and 6G network access at the same time, in the area without 6G signal coverage, the UE can use the 5G network to carry out business, or in the area where 5G and 6G networks provide coverage at the same time, the UE can use 5G network and 6G network at the same time to carry out business, so as to share the load of single network or speed up data transmission. For this, the URSP rule supported by the 5G network also needs to be supported by the 6G network.

[0166] In some embodiments, please refer to FIG. 1b, the present disclosure is based on the interworking architecture of the 5G network and the 6G network. Among them, 5G-RAN is a 5G access network, 6G-RAN is a 6G access network, 5G-Access and Mobility Management Function (AMF, Access and Mobility Management Function) is a network function responsible for user access management in the 5G network, 6G-AMF is a function responsible for user access management in the 6G network, 5G / 6G-User Plane Function (UPF, User Plane Function) is a user plane function shared by the 5G network and the 6G network, 5G / 6G-Session Management Function (SMF, Session Management Function) is a function responsible for user session management shared by the 5G network and the 6G network, Session Management (SM, Session Management) / UE-Policy Control Function (PCF, Policy Control Function) is a function responsible for policy management related to user access service and user session management shared by the 5G network and the 6G network, and Data Network (DN, Data Network) is a data network service accessible by the user.

[0377] Example 1

[0378] Referring to FIG. 6a, a communication method is provided, the method comprising:

[0379] Step S6101: sending a PDU session establishment request message.

[0380] In some embodiments, the UE registers with a 5G network and initiates a protocol data unit (PDU) session establishment request to a session management function (SMF) through a 5G-access and mobility management function (AMF).

The UE-PCF is responsible for the access policy of the UE. An indication “support providing URSP rules over 6G” is also sent to the UE-PCF.

[0395] In some embodiments, if the UE-PCF also supports providing URSP rules over 6G, it generates URSP rules for the 6G network.
