Abstract: The invention includes a method and apparatus for providing IMS service at the customer premises independent of the core IMS network. A method includes receiving, at a premises gateway to a core IMS network, a request for a service normally provided by the core IMS network, and, in response to a determination that the requested service is capable of being provided locally by the premises gateway, providing the requested service locally at the premises gateway independent of the core IMS network.

Abstract: The invention includes a method and apparatus for interfacing with a managed device. A method according to one embodiment includes receiving a message including an identifier indicative of a location at which interface information associated with the managed device is stored, obtaining the interface information, and initiating a request to perform a function on the managed device using the interface information. The interface information includes information adapted for use by a management system to interface with the managed device. The interface information includes one or more interface routines and one or more interface routine descriptions. The interface routine(s) is specified using an interpreted language, such as Java, Visual Basic, and the like. The interface routine description is specified using a descriptive language, such as XML, XHTML, and the like.

Abstract: The invention includes a method and apparatus for exchanging messages between user devices served by a premises gateway and components of a core IMS network. A method for propagating messages toward a core IMS network includes receiving, at a premises gateway, a message from a user device that is intended for the core IMS network and is formatted according to a first protocol, identifying the first protocol according to which the received message is formatted, translating the message from being formatted according to the first protocol to being formatted according to a second protocol, and propagating the message formatted according to the second protocol toward the core IMS network.
