摘要

A method and apparatus for providing user access information to a Home Subscriber Server in an IP Multimedia Subsystem, the method comprising transmitting a message from User Equipment to a Call Session Control Function, the message including a P- Access-Network-Info header, transmitting access information contained in the P- Access-Network-Info header from the Call Session Control Function or an Application Server to a Home Subscriber Server, and at the Home Subscriber Server, storing the received access information. This allows for control of, for example, user access to an IP Multimedia Subsystem on the basis of the access network used or the user location.
