Cooperative IMS access from a visited domain
First Claim
1. A method of operating broadband access equipment to provide roaming IP multimedia subsystem (IMS) access, the method comprising:
- in a communication interface, attaching a communication device to provide the communication device with access to a broadband access network associated with a visited domain of the communication device;
in a proxy call session control element of a broadband services gateway (BSG);
registering the communication device to access IMS services on behalf of an IMS core in the visited domain over the broadband access network;
conveying Session Initiation Protocol (SIP) signaling between the communication device and the IMS core as a SIP proxy; and
establishing a communication session between the communication device and the IMS core.

Abstract
Embodiments disclosed herein provide systems, methods, and computer readable media to provide roaming IP multimedia subsystem (IMS) access. In a particular embodiment, a method provides, in a communication interface, attaching a communication device to provide the communication device with access to a broadband access network associated with a visited domain of the communication device. The method further provides, in a proxy call session control element of a broadband services gateway (BSG), registering the communication device to access IMS services on behalf of an IMS core in the visited domain over the broadband access network, conveying Session Initiation Protocol (SIP) signaling between the communication device and the IMS core as a SIP proxy, and establishing a communication session between the communication device and the IMS core.
