  • Publication number: 20240259980
    Abstract: The present disclosure provides a method and an apparatus for user equipment (UE) registering, an electronic device and a storage medium. Under 5G core network slice isolation networking, when an AMF network element detects that a UE is unsuccessfully registered on the AMF network element, the AMF network element sends to the UE a registration reject message comprising at least a first cell and a second cell. In this way, when the UE sends registration information again, the UE can select target network slice information based on network slice information configured in the first cell. And a 5G base station, when receiving the registration information from the UE, determines a corresponding target AMF network element based on the target network slice information in the requested NSSAI, such that the UE can be successfully registered to the target AMF network element.
