1. A method for providing Internet protocol multimedia subsystem (IMS) registration service to a non-IMS subscriber terminal, the method comprising:
- (a) identifying non-registration activity involving a non-IMS subscriber terminal, wherein the non-IMS subscriber terminal lacks IMS registration signaling capabilities; and
(b) in response to identifying the non-registration activity involving the non-IMS subscriber terminal, performing an IMS registration operation on behalf of the non-IMS subscriber terminal, wherein performing the IMS registration operation includes performing the IMS registration operation automatically in response to detecting the non-registration activity involving the non-IMS subscriber terminal by identifying at least one of an ISUP, TCAP, MAP, INAP, and CAMEL message associated with the non-registration activity involving the non-IMS subscriber terminal.

16. A system for providing Internet protocol multimedia subsystem (IMS) service registration service to a non-IMS subscriber terminal, the system comprising:
-
(a) a call session control function (CSCF) for maintaining IMS registration information; and (b) an IMS proxy for identifying non-registration activity involving a non-IMS subscriber terminal, wherein the non-IMS subscriber terminal lacks IMS registration signaling capabilities and performing an IMS registration operation on behalf of the non-IMS subscriber terminal to register the non-IMS subscriber terminal with the CSCF, wherein performing the IMS registration operation includes performing the IMS registration operation automatically in response to detecting the non-registration activity by identifying at least one of an ISUP, TCAP, INAP, and CAMEL message associated with the non-registration activity involving the non-IMS subscriber terminal. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
