Original Abstract Submitted
Methods, system and apparatus are provided to perform network slice admission control within a service area of an operator network and across service areas of the operator network. A central Network Slice Admission Control Function (NSACF) supporting multiple service areas of at least one operator network receives an admission request from a network function (e.g., AMF, SMF or SMF+PGW-C) belonging to a service area of an operator network. The admission request includes information identifying the service area and may include an identifier of the network operator. The central NSACF performs network slice admission control based on whether the UE is newly admitted to the network slice in the service area or whether the UE has already been admitted in a different service area.
