Abstract
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 radiocommunication 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.
