Online charging for sessions that are transferred between network domains
First Claim
1. A system operable to provide online charging for a session of a dual mode device that is transferred from a first network domain to a second network domain, the system comprising:
- at least one network element in the second network domain that is operable to receive a handover charging identifier for the session that was handed over from the first network domain to the second network domain, wherein the handover charging identifier identifies the session for online charging across the first network domain and the second network domainthe at least one network element is further operable to store the handover charging identifier, to identify a triggering event for charging during the session over the second network domain, to generate an online charging request for the session and insert the handover charging identifier in the online charging request, and to transmit the online charging request to an online charging system.

Abstract
Communication networks and methods are disclosed for providing online charging for a session of a dual mode device that is transferred (seamless handover) from a first network domain to a second network domain. For the session involving the dual mode device, a handover application server or another network element generates a handover charging identifier that may be used in the first network domain and the second network domain. The handover application server then distributes the handover charging identifier to network elements in the second network domain and the first network domain. The network elements in the first network domain and the second network domain insert the handover charging identifier and other context information in online charging requests that are transmitted to an online charging system. The online charging system is then able to correlate online charging requests from both the first network domain and the second network domain.

17. A method of operating a handover application server to provide online charging for a session of a dual mode device that is transferred from a first network domain to a second network domain, the method comprising:
-
receiving a session initiation request from at least one network element that is serving the session in the second network domain which was handed over from the first network domain identifying a handover charging identifier for the session; and distributing the handover charging identifier to the at least one network element in the second network domain indicating the handover charging identifier to be used in online charging requests to an online charging system; wherein the handover charging identifier is assigned for online charging for the session over the first network domain and the second network domain. - View Dependent Claims (18, 19, 20)
