The charging system then inserts the original ICID and the handover ICID in a CDR for the session. When the session ends, the charging system may use the original ICID and the handover ICID to correlate multiple CDRs for the session. Thus, even if CDRs for the same session have different ICIDs, the charging system is able to correlate the CDRs.

The application relates priority services such as the Government Emergency Telecommunication Service GETS or the Wireless Priority Service WPS which provide priority service to National Security/Emergency Preparedness personnel. In times of emergency or crisis or because of natural or other catastrophes, telecommunication networks can become congested. Throttling mechanisms such as call gapping are employed to limit the number of priority call/session requests accepted from a give source and/or handled by a given network node. However, present mechanisms rely on historical traffic levels rather than adapting to actual traffic level. This problem is solved in that parameters of the call gapping function are dynamically regulated. The method includes: monitoring a rate at which priority service requests are received at a node of the network; comparing the rate to a threshold; disabling a gapping function for priority service traffic when the rate is less than the threshold; enabling the gapping function for priority service traffic when the rate is not less than the threshold, and, dynamically regulating a parameter of the gapping function when the gapping function is enabled.

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 portion of the profile information.

Communication networks (100) and methods are disclosed for sharing charging information between a home IMS network (110) and a visited IMS network (120). If a signaling message for a session is received in the visited IMS network (120), the visited IMS network (120) assigns a visited charging identifier, such as an ICID, and shares the visited charging identifier with the home IMS network (110) through signaling messages. Similarly, the home IMS network (110) assigns a home charging identifier, and shares the home charging identifier with the visited IMS network (120) through signaling messages. When CDRs are generated in the home IMS network (110) and the visited IMS network (120), the networks include the home charging identifier and the visited charging identifier in the CDRs so that billing systems (116, 126) may more easily correlate the CDRs from the different IMS networks (110, 120).
