Abstract
A method of a Session Management Function (SMF) apparatus includes communicating with a Network Slice Admission Control Function (NSACF) apparatus and sending a message to the NSACF apparatus for a Network Slice Admission Control (NSAC). The message includes information related to a handover from Evolved Packet System (EPS) to 5th Generation System (5GS) and information indicating the NSACT is not supported in the EPS.
Claims6
A method performed by a Network Slice Admission Control Function (NSACF), the method comprising:
- receiving, from an Access and Mobility Management Function (AMF), a request including an identifier of a User Equipment (UE);
- based on UE admission being above a threshold, checking a presence of an indication in the request, wherein the indication is related to the UE already being registered and mobility of the UE from an Evolved Packet System (EPS) to a 5G System (5GS);
- and
- based on the presence of the indication in the request, accepting the request.
