Call control with converged application server logic and gateway logic in IMS networks
First Claim
1. An IP Multimedia Subsystem (IMS) call control node for providing online charging in an IMS network, the IMS call control node comprising:
- a first interface for communicating with a call session control function (CSCF) according to a first protocol;
a second interface for communicating with an online charging server (OCS) according to a second protocol;
a processing system coupled to the first interface and the second interface;
application server (AS) logic executable by the processing system to provide a plurality of services; and
gateway logic executable by the processing system;
the processing system;
receives a call message from the CSCF through the first interface according to the first protocol, determines whether to execute the AS logic or the gateway logic responsive to the call message, executes the AS logic to perform a service responsive to a determination to execute the AS logic, and executes the AS logic to contact the OCS for online charging for the service through the second interface according to the second protocol.

Abstract
IMS call control nodes and methods are disclosed for providing online charging in an IMS network. An IMS call control node receives a call message from a CSCF through a first interface for a call session, and determines whether to execute Application Server (AS) logic or gateway logic responsive to the call message. If the processing system determines that the call message should be processed with the AS logic, then the processing system executes the AS logic to perform a service and to contact the OCS for online charging for the service. If the processing system determines that the call message should be processed with the gateway logic, then the processing system executes the gateway logic to perform call session control and to contact the OCS for online charging for the call session.
