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.
