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

providing, via said broadband gateway without using said one or more other broadband gateways, access to content of a first service by said first device in accordance with said security features of said first authorized service domain of said broadband gateway; and
detecting, by said broadband gateways, that said first device has roamed to said one or more other broadband gateways;
wherein negotiating said common authorized service domain comprises negotiating said common authorized service domain responsive to detecting that said first device has roamed to said one or more other broadband gateways, said common authorized service domain allowing seamless access to said content of said first service via said one or more other broadband gateways by said first device.
6. The method according to claim 3 , wherein said one or more other broadband gateways perform functionality conversion to support said gateway functionality for said one or more services.
7. The method according to claim 1 , comprising:
receiving said content for said one or more services from said at least one network access service provider;
determining whether said content is related to a location of at least one of said broadband gateway or said one or more other broadband gateways; and
responsive to determining that said content is related to said location, communicating said content to said one or more other broadband gateways via said one or more communication links.
8. The method according to claim 7 , comprising selectively communicating said content to said one or more other broadband gateways via said one or more communication links based on location information for said one or more other broadband gateways.
9. The method according to claim 6 , wherein said one or more other broadband gateways:
receive other content for said one or more services from said at least one network access service provider; and
communicate said other content to said broadband gateway via said one or more communication links based on said common authorized service area.
10. A system for networking, the system comprising:
one or more circuits in a broadband gateway that enable 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, said one or more circuits being configured to:
negotiate, 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;
establish 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 communicate, 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.
11. The system according to claim 10 , wherein said one or more circuits is further configured to negotiate at least one of communication technology types, service provider preferences, security features, remote access, content processing capabilities, software platforms, protocols, applications, or interfaces.
12. The system according to claim 10 , wherein said one or more circuits are configured to communicate information about a gateway functionality for said one or more services to said one or more other broadband gateways.
13. The system according to claim 12 , wherein said one or more circuits are configured to forward at least one software structure interface or signaling protocol for said gateway functionality to said one or more other broadband gateways.
14. The system according to claim 13 , wherein said one or more other broadband gateways are configured to port said gateway functionality for said one or more services.
15. The system according to claim 12 , wherein said one or more other broadband gateways are configured to perform functionality conversion to support said gateway functionality for said one or more services.
16. The system according to claim 10 , wherein said one or more circuits are configured to:
receive content for said one or more services from said at least one network access service provider;
determine whether said content is related to location information of said one or more other broadband gateways; and
responsive to determining that said content is related to said location information, communicate said content to said one or more other broadband gateways via said one or more communication links.
