A communication system includes a satellite communication system segment having at least one satellite, that projects a plurality of beams on the surface of the earth, and at least one terrestrial satellite gateway that is bidirectionally coupled to the at least one satellite and also to a terrestrial communications system. One or more beams from one or more satellites at the surface of the earth define a regional service area within which at least one Wireless Local Loop (WLL) service region is located. The communication system further includes a terrestrial communication segment having at least one WLL base station, capable of bidirectional communications with a plurality of WLL user terminals within the WLL service region, and a virtual gateway that is bidirectionally coupled to the WLL base station and to the at least one satellite. The virtual gateway is responsive to the terrestrial satellite gateway for temporarily assuming control of some satellite system resources for bidirectionally coupling a communication to or from an individual one of the WLL user terminals into or out of the WLL service region.
