Abstract:
1. A method for routing a bearer path in a wireless communication system, the method comprising: receiving an invitation to a communication session between an originating mobile station and a terminating mobile station; determining whether Internet Protocol Multimedia Subsystem (IMS) core network bearer associated services are required for the communication session such that a bearer path of the communication session will need to be routed to an IMS core network in order to provide such services; when the communication session does not require the IMS core network bearer associated services that require that a the bearer path of the communication session be routed to the IMS core network, routing a bearer path over an interface between a first Node B serving the originating mobile station and a second Node B serving the terminating mobile station; and concurrent with routing the bearer path over the interface between the first Node B and the second Node B, routing a signaling path for the communication session between the first Node B and the second Node B via the IMS core network to allow the IMS core network to maintain control over the communication session.
