Abstract: A call routing system for use with a wireless telephone systems is disclosed. The system, which monitors the subscriber's current physical location, determines the device to which a call should be terminated, and routes the call. The device can be any IP telephone, including a cable television system adapted to IP telephony. The system routes calls without direct subscriber actions, without a second telephone number, regardless of the time of day and day of week. Various options can also apply to a call, determined by subscriber-established preferences, when specified criteria are met, or calls can be limited to/from specified telephone numbers. The system and method uses signaling techniques that will allow routing of the call, along with any authorization or restrictions, to be done remotely from the actual switching of the call. Call events are transmitted to the call routing system while the communications path of the call is held at the switching system awaiting call routing information.

Abstract: A telephone system supports communication with user devices over both a cellular radio network as well as over an Internet Protocol (IP) network, and enables roaming and active call handoff between cellular and IP domains. Components of the system interact with conventional cellular telephone systems, for example, by emulating behavior of control components, providing proxy services for conventional components, transporting cellular telephone control communications over IP connections, or by simulating cellular operating characteristics of user devices operating in an IP domain.

Abstract: A pre-paid subscriber account system for use with wireless telephone systems is disclosed. The system, which monitors a subscriber's call, deducts the cost of the call from the subscriber's pre-paid account in real-time, warns the subscriber during a call when the account is nearing depletion, and terminates the call when the account is depleted. The system can also prevent the initiation of a new call when the account is depleted. The system and method uses signaling techniques that will allow the metering or billing of the call, along with any authorization or restrictions, to be done remotely from the actual switching of the call. Call events or chargeable events are transmitted to the pre-paid control system while the communications path of the call is held at the switching system awaiting control information.

The system, which monitors a subscriber's call, deducts the cost of the call from the subscriber's pre-paid account in real-time, warns the subscriber during a call when the account is nearing depletion, and terminates the call when the account is depleted. The system can also prevent the initiation of a new call when the account is depleted. Various options can also apply different charging rates, can charge only when specified criteria are met, or can charge only for calls to/from specified areas or telephone numbers. The system and method uses signaling techniques that will allow the metering or billing of the call, along with any authorization or restrictions, to be done remotely from the actual switching of the call. Call events or chargeable events are transmitted to the pre-paid control system while the communications path of the call is held at the switching system awaiting control information.
