ABSTRACT:
In a communication network that provides a path through a cable IP network between sending and receiving terminals residing on respective networks (e.g., an HFC, and/or PSTN network) controlled by different network managers or service providers, a controller hands off control of service access of the terminals between the service providers. Subscriber terminals may include broadband telephony interfaces, cable modems, or multimedia terminal adapters. To effect hand-off control, configurable modules of the terminals enable them to respond directly to a network manager (e.g., cable modem termination system or call management server) according to instructions supplied by the controller based either on subscriber authorization, database information, call type, dialing plan, and/or other parameters. Transfer of call control may also occur on a call-by-call basis. Further, a usage server collects network usage information of the respective terminals or subscribers to determine user fees between competitive networks.
