Claim:
1. A method comprising: receiving, at a gateway, a request from a device to establish a service connection between the device and an endpoint through an Internet Protocol Multimedia Subsystem (IMS) session, determining, at the gateway, whether the request has already been authenticated; in response to determining the request has already been authenticated: extracting, at the gateway, the third-party domain credentials from the request received from the device; establishing, via the gateway, a trust relationship with the third-party domain to enable the third-party credentials to be authenticated, communicating, via the gateway, the third-party domain credentials to the third-party domain to verify the third-party domain credentials; and, establishing the IMS session between the initiating device and the endpoint upon verification of the third-party domain credentials based on the end user's third-party domain credentials, authenticated by the third-party domain, to authenticate use of an IMS core network by the end-user, to thereby authenticate use of the IMS core network, without the need for further validation of credentials of the end-user because of the trust relationship between the gateway and the IMS core network,
