Method and system for porting gateway functionality associated with a user from a first gateway to one or more other gateways

摘要

A broadband gateway, which enables communication with a plurality of devices, handles at least one physical layer connection to at least one corresponding network access service provider. The broadband gateway may operate as a home gateway to negotiate with one or more visited gateways, a common authorized service area or domain (ASD) for providing services to the visited gateways. The home gateway may establish one or more corresponding communication links with the visited gateways based on the negotiated common ASD. The home gateway communicates corresponding content for the services to the visited gateways via the established corresponding communication links. The home gateway communicates information about gateway functionalities required for the services to the visited gateways. The visited gateways may port gateway functionalities forwarded by the home gateway, or may perform gateway functionality conversion to support the services, which may be acquired via the home gateway and/or the visited gateways from networks.

1. A method for networking, the method comprising:
in a broadband gateway that enables communication with a plurality of devices including a first device, wherein said broadband gateway is configured to handle at least one physical layer connection to at least one network access service provider: negotiating, with said one or more other broadband gateways, a common authorized service domain for providing one or more services from said broadband gateway to the first device via said one or more other broadband gateways according to a comparison between security features of a first authorized service domain of said broadband gateway established with the at least one network access service provider, and a second authorized service domain of said one or more other broadband gateways established with the at least one network access service provider, said common authorized service domain comprising at least one security feature common between said first authorized service domain and said second authorized service domain for providing said one or more services, said at least one common security feature comprising applying a first set of security policy constraints determined for said common authorized service domain, to content communicated between said broadband gateway and said one or more other broadband gateways; establishing one or more communication links between said broadband gateway and said one or more other broadband gateways based on said common authorized service area; and selectively communicating, in accordance with said first set of security policy constraints determined for said common authorized service domain, content for said one or more services to said one or more other broadband gateways via said one or more communication links.
