This service provides: - AMF access

43、 control and mobility management related policies to the AMF; and - UE policies such as the UE Route Selection Policy to the UE via the AMF; and offers the following functionalities: - policy creation based on a request from the AMF during UE registration; - notification of the AMF of the updated po

The Policy and Charging related 5G architecture is also des

45、cribed in 3GPP TS 29.513 7. The Access and Mobility Policy Control Service (Npcf_AMPolicyControl) is part of the Npcf service-based interface exhibited by the Policy Control Function (PCF). The known consumers of the Npcf_AMPolicyControl service are the Access and Mobility Management Function (AMF)

46、and the Visited Policy Control Function (V-PCF). The AMF accesses the Access and Mobility Policy Control Service at the PCF via the N15 Reference point. In the roaming scenario, the N15 reference point is located between the V-PCF in the visited network and the AMF. The V-PCF accesses the Access and

47、 Mobility Policy Control Service at the Home Policy Control Function (H-PCF) via the N24 Reference point.
