Abstract: A communication network system comprising core network nodes, CNN, such as Session Management Function, a Policy Control function, PCF, an Online Charging System, OCS, and a Network Exposure Function, NEF, the system further comprising a radio access node, RAN, and a User Entity, UE, the system further comprising a user plane function, UPF, communi-cating with a data network, DN; and a control plane, which again comprises at least a control plane comprising an Access Mobility Function, AMF, the system being adapted for the AMF—retrieving (301,) or determining a registration area, RA, for the UE. The CNN—retrieving (4-2,) a service area such as a a TA or TAI, and—allocating a Presence Reporting Area, PRA, —informing (302;) the AMF of the PRA. The AMF—defining (303A) or retrieving (303B) a UE Reporting Area, URA, in dependence of the RA and the PRA, —transmitting (304) the URA, to the UE, or—transmitting (305) the URA to the RAN.
