Abstract: A system and method for communicating between ground stations and mobile satellites effectively eliminates the need for transferring information from one ground station to another. Communication between a ground station and a mobile satellite is accomplished via an intermediate network of geosynchronous control satellites. The mobile satellite is positioned within a three-dimensional cellular grid formed by the network of geosynchronous satellites. This system is particularly applicable to a terrestrial network communicatively coupled to the geosynchronous network via one or more ground stations. The terrestrial network of ground stations no longer needs to perform expensive, time-consuming and manual synchronization and hand-off procedures.

Abstract: An apparatus in one example has: at least a first network of a first predetermined type and at least a second network of a predetermined type; at least one mobile terminal movable between the first and second networks; at least one gateway operatively coupled to each of the first and second networks; and at least one message that communicates via the gateway at least feature data of the mobile terminal from one of the first and second networks to the other of the first and second networks.
