Telecommunication services are provided to subscriber-provided radiotelephones (50) residing inside an aircraft (20). Telecommunication services are provided while the aircraft (20) is flying and utilize the aircraft's air-to-ground communication system (48) to access a radio communication link (34). Base stations (40) residing in aircraft (20) are configured to transmit at least two independent overhead control data pilot signals (54, 58) in response to instructions from a single controller (44). The control data pilot signals (54, 58) capture and control the subscriber-provided radiotelephones (50). Controlling methods are employed to force autonomous registration of radiotelephones (50) and to instruct radiotelephones (50) to transmit at minimum power levels.

[ What is claimed is:] [1.]1. In a network of cellular communication systems in which a multiplicity of subscriber-provided radio communication devices communicate over a wide region through a plurality of cellsites that share common communication channels, a method of controlling telecommunication services to said subscriber-provided radio communication devices residing in an area, said area being inside of and smaller than said region, said method comprising the steps of:providing one of said cellsites in said area;establishing a forward communication portion of said cellsite in said area, said forward communication portion simulating forward communication over one of an A-side and a B-side cellular communications system; andoperating said forward communication portion in a passive mode to prevent said subscriber-provided radio communication devices residing in said area from transmitting, said operating step including:broadcasting a control data pilot signal over a forward control channel of said common communication channels, said forward control channel being a forward control channel for said one of said A-side and B-side systems, and said control data pilot signal instructing said subscriber-provided radio communication devices residing in said area to refrain from transmitting; andsetting a busy/idle bit of said control data pilot signal to busy prior to said broadcasting step.
