Control of User Equipment Identity Dependent Service

The present disclosure relates to methods and an identity mediator node for controlling a user equipment, UE, identity, ID, dependent service in a radio base station, RBS of a wireless network. The method comprises receiving (S1) from a Mobility Management Entity, MME, a UE ID report comprising a permanent UE ID, a temporary UE ID, and a serving RBS identity for an RBS serving the UE, wherein the temporary UE ID represents an identifier for the UE in the serving RBS. The identity mediator node stores (S2) a record associating the temporary UE ID, the serving RBS identity, and the permanent UE ID record. When an order to activate a UE ID dependent service for a permanent UE ID is detected (D1) in the identity mediator node, the identity mediator node retrieves (S4) the temporary UE ID and serving RBS identity from the stored record. A request is sent (S5) to the serving RBS to activate the UE ID dependent service for the UE, wherein the request includes the temporary UE ID.
