Provision of Access Information in a Communication Network

摘要

A method and apparatus for providing user access information to a Home Subscriber Server (HSS) in an IP Multimedia Subsystem (IMS) network. A User Equipment transmits to a Call Session Control Function (CSCF), a message containing a P-Access-Network-Info (PANI) header. The CSCF or an Application Server then sends user access information retrieved from the PANI header to the HSS, which stores the information. The stored information can be used to control access to the IMS network based on the access network being utilized or the user location.
