BILLING FOR CALLS AND ROUTING OF BILLING INFORMATION IN AN INTERNET PROTOCOL MULTIMEDIA SUBSYSTEM

摘要

An exemplary method implemented in a telecommunication network generates a charging data record (CDR) for a subscriber that is supported by a visited network while away from the subscriber's home network. A request is transmitted from a first node in the visited network for profile information about the subscriber to be obtained from the home subscriber server (HSS) in the subscriber's home network. A reply is received at the first node in the visited network in response to the request where the reply includes at least a portion of the profile information about the subscriber stored in the HSS of the subscriber's home network. The first node stores the at least portion of the profile information received in the reply, and generates the CDR associated with the subscriber as supported in the visited network where the CDR includes subscriber data derived from the stored at least portion of the profile information. The CDR is transmitted by the first node to another node in the telephony network to be used to determine billing associated with services provided to the subscriber.
