1 Scope p. 7
The present document specifies the Converged Charging description for Network Slice Admission Control charging in the 5G System (5GS), based on Network Slice Admission Control Function (NSACF) of 5GS architecture and procedures specified in TS 23.501 and TS 23.502.
The charging aspect of Network Slice Admission Control charging is based on charging principles specified in TS 32.240.
The following functionalities of Network Slice Admission Control are within the scope:
- number of registered UEs per network slice;
- number of PDU Sessions per network slice.
