In 102, if the UE determines that the handover condition is met according to the network side support for the network service, the handover procedure is initiated to complete the handover.

The UE can obtain the network side support for the network service sent by the AMF in the registration process.

Specifically, the UE may initiate a registration procedure to the NG-RAN, so that the NG-RAN reports its support for the network service to the AMF. Further, the UE may obtain the network side support for the network service returned by the AMF.

2 is a schematic diagram of the registration process of the present invention.

As shown in FIG. 2, in step 3, the NG-RAN may send a registration request (Registration Request) message to the AMF (New AMF), where the NG-RAN may be carried. Support for network services.

In step 22, the AMF sends a registration acceptance (Registration Accept) message to the UE, where the network side can support the network service.

The AMF obtains the support of the NG-RAN for the network service reported by the NG-RAN, and knows its own support for the network service, that is, the support of the 5GC for the network service, then the NG-RAN and the 5GC can support the network service. In this case, the UE side returns the network side support for the network service.
