As shown in FIG. 1 , in one aspect, the UE policy includes a static policy and a dynamic policy. On the other hand, the UE policy includes a WLAN SP and a URSP. Note: The NSSP and the DNN in the RSD may have one or more values. The following is an example of WLANSP and URSP by code.

WLANSP example

URSP policy example

The relevant content is formulated for URSP, as shown in Table 1 and Table 2 below, where Table 1 describes the URSP Rule and Table 2 describes the RSD.

Data Network). In the first step, the UE sends a single network slice selection assistance information (S-NSSAI, Single Network Slice Selection Assistance Information), DNN, access type (Access Type), PDU session ID (PDU Session ID), etc. to the network side. The network establishes the required PDU Session for the UE. Each time a PDU session is established, the network side will inform the UE (including the EPS Bearer ID and the mapped QoS parameter) of the mapped Evolved Packet Syste (QoS, Quality of Service) information. When the UE needs to perform the 5G to 4G handover, the network side maps according to the EPS QoS information previously sent to the UE. A part of the existing PDU Session/Flow may be merged into the default bearer, and some of the PDU Session/Flow will be mapped into a dedicated payload.
