  • Patent number: 6438355
    Abstract: A method and system enables optimal call routing in a satellite communications network when a satellite subscriber has, for example, call forwarding active. Many satellite networks re-register a satellite subscriber's (e.g., the A-subscriber's) subscription information to a satellite gateway that is most cost efficient when the satellite subscriber initiates an outgoing call. If the called party (e.g. the B-subscriber) is distant from the satellite subscriber's home country, the distant gateway to which the re-registration occurs is likely to be far from the gateway of his or her native country, which is often to where call forwarding is directed. When an incoming call from a C-subscriber is detected for the A-subscriber, the call is handled normally until call forwarding is detected in the distant gateway. Once call forwarding is detected, a satellite gateway through which the call will be completed (e.g.
