Abstract
Methods performed in a core network (110) for dynamically handling access and mobility service areas with different capabilities in a communication system (100) are disclosed. The methods are carried out in an AMF node (111), a UDM node (112), a PCF node (113) and a SMF node (115). The UDM node (112) configures Service Area Restriction (SAR) data in a subscription data for a UE (120). The SAR data includes a number of service areas allowed or restricted for the UE and, for each service area, a service area identifier, a service area type and a service area definition. The PCF node configures a Service Area Definition (SAD) rule for a UE. The SAD rule comprises a service area definition and an indication of a set of service area characteristics enabled in the service area. During a registration procedure, the SAR data and SAD rule may be provided to the AMF node upon request for a UE communication. The AMF node then takes actions for the UE communication based on anyone of the SAR data, the SAD rule and local policies at the AMF node. During a session management procedure, the SMF node (115) receives service area related information with a service area identifier and a service area …
