Abstract There is provided a mechanism for networking satellite and terrestrial networks. It comprises: maintaining subscriber-received power levels of terrestrial network transmissions about one order of magnitude above co-channel satellite transmissions to overcome interference and maintaining subscriber transmissions to terrestrial networks at power levels about one order of magnitude of the below co-channel transmissions to satellite networks to avoid causing interference at the satellite. Such power level maintenance is provided by the network in communication with such subscriber. Moreover, a non-orbiting ("grounded") satellite cooperates as a switching node of both the satellite network and a terrestrial network to relay information between a terrestrial subscriber and the satellite radiotelephone network over a terrestrial network. The terrestrial network and the satellite network may communicate via either the inter-satellite spectrum or the terrestrial-to-satellite spectrum.
A method of controlling a satellite network (301-303) and a terrestrial network (310, 312-315) to avoid co-channel transmission interference, characterized by: maintaining a subscriber-received power level of a terrestrial network transmission (317, 340-342, 360) path loss above a co-channel satellite transmission (320, 343, 365); and maintaining a subscriber transmission (340, 341, 360) to the terrestrial network (310, 312-315) at a power level at least one order of magnitude of a differential path loss below a co-channel transmission (320, 365) to the satellite network (301-303).

The method of claim 1, characterized by: maintaining the subscriber-received power level of the terrestrial network transmission (317, 340-342, 360) at least one order of magnitude of a differential path loss above the co-channel satellite transmissions (320, 343, 365); and maintaining the subscriber to the terrestrial network transmissions (340, 341, 360) at a power level sufficiently at least one order of magnitude of a differential path loss below the co-channel transmission (320, 365) to the satellite network (301-303), wherein such power level maintenance is provided by one of the satellite and terrestrial networks in communication with a subscriber (330-333).

An apparatus for controlling a satellite network (301-303) and a terrestrial network (310, 312-315) to avoid co-channel transmission interference, characterized by: first control device for controlling a subscriber-received power level of a terrestrial network transmission (340, 341, 360) about one order of magnitude of a differential path loss above a co-channel satellite transmission (320, 365); and second control device, coupled to said first control device, for controlling a subscriber transmission (340, 341, 360) to the terrestrial network (310, 312-315) at a power level about one order of magnitude of a differential path loss below a co-channel transmission (320, 365) to the satellite network (301-303), wherein such power level maintenance is provided by one of the satellite and terrestrial networks in communication with a subscriber (330-333).
