Abstract:

Methods and apparatus for implementation of an Application Sever, AS, (300), a Serving Call Session Control Function, S-CSCF, (200) and a Home Subscriber Server, HSS, (100) in an Internet Protocol Multimedia Subsystem, IMS. A service monitor (318) of the AS monitors usage by one or more user equipments, UE, of one or more services offered in the IMS and an event manager (320) triggers an event, based on the monitored usage, the event comprising an update on at least one of a network operation and a UE operation for the one or more UEs in the IMS. The event manager controls a transmitter (302) to transmit an event notification to the S-CSCF, the event notification including the update on the at least one of a network operation and a UE operation. A registration manager (220) of the S-CSCF triggers an adaptation of the at least one of the network operation and the UE operation based on the received event notification.
