Abstract: A hybrid constellation satellite communication system (100) is established using two or more satellite types (110, 120) in different constellations. The two or more satellite types (110, 120) are connected to system control centers (140) via control links (105, 135) which provides a communication path from the satellite constellations to the system control centers (140). The two or more satellite types (110, 120) are also connected to subscriber equipment (150) via subscriber links (155, 145) which provides a communication path from the satellite constellations to the subscriber equipment (150). The first type of satellites (110) are interconnected using upper inter-satellite links (115). The second type of satellites (120) are interconnected using lower inter-satellite links (125). Control services and other time delay non-sensitive services are provided using communication channels established using the first type of satellites (110). Time delay sensitive services are provided using communication channels established using the second type of satellites (120). There are no inter-satellite links between satellites in the two different constellations.

Abstract: A communication system (10) includes a population of mobile units (24) which communicate with a control station (29). Communications take place between the control station (29) and the mobile units (24) so that the system (10) may gain knowledge about the mobile units' locations. The mobile units (24) occasionally initiate such communications automatically. The control station (29) sends data defining a target area (72, FIG. 5) to the mobile units. The mobile units (24) reside in the target areas (72) when the target areas (72) are first assigned, but the mobile units (24) are free to move. The control station (29) transmits broadcast signals to geographically spaced apart cells (36, FIG. 2). The broadcast signals convey current data identifying the service areas covered by the cells (36). The mobile units (24) automatically initiate communications when their assigned target areas (72) do not coincide with the service areas for the broadcast signals they can receive.

Abstract: A satellite communication system provides users with global cellular coverage. To facilitate delivery of calls to users having subscriber units, a fixed channel is defined wherein subscriber units are notified of incoming calls. Subscriber units monitor this ring alert channel and examine subscriber unit IDs transmitted in a ring alert message contained therein. When a subscriber unit determines from the subscriber unit ID that a call is being directed to it, it calls into a network to receive a call. Subscriber units also monitor this fixed channel to receive a control channel directory identifying the location of a subscriber unit's broadcast (control) channels.

Abstract: In a communication system having Low Earth Orbit (LEO) satellites (210), one or more Mission Operations Control Centers (MOCCs) (220), one or more Distributed Virtual Network Managers (DVNMs) (230), and several types of Customer Premises Equipment (CPE) (250, 260, 270, and 280), individual service providers (20) are able to control the network services they provide independently from other service providers (20) through local management of the DVNMs (230).

Abstract: A channel management process (68) is performed by a parent base station (36) of a radio telecommunications system (20) that exchanges channel usage data with neighbor base stations (38) within its local group (34). When channel usage data indicates a channel assignment conflict, that conflict is resolved in the base station (22) having the lesser loading of the pair of conflicting base stations (22). Channel usage requests received by a base station (22) are prioritized and sequentially processed, channels (58) being assigned for inter-cell handoff requests, then intra-cell handoff requests after inter-cell handoff requests, even when that assignment creates a conflict, and then channels (58) being assigned to new call requests after handoff requests if that assignment does not create a conflict.
