1. Cellular radio communication apparatus, located in an aircraft, operable to provide communication services to ground-based cellular mobile subscriber stations that are located in said aircraft, via a non-terrestrial cellular mobile cellular communications, comprising:

  • first amplifier means, responsive to receipt of radio frequency communication signals from non-terrestrial cell sites and in a mode compatible with non-terrestrial cellular communications for amplifying said received non-terrestrial cellular signals;

    second amplifier means, responsive to receipt of radio frequency communication signals from ground-based cellular mobile subscriber stations and in a mode compatible with ground-based cellular communications, for amplifying said received ground-based cellular signals;

    control channel frequency translation means for exchanging control signals from control channels on said received ground-based cellular signals to control channels on non-terrestrial cellular control channels and from control channels on said received non-terrestrial cellular signals to control channels on ground-based cellular control channels;

    first transmitter means for transmitting said amplified received non-terrestrial cellular signals and said control signals, exchanged from control channels on said received non-terrestrial cellular signals to control channels on ground-based cellular control channels, to said ground-based cellular mobile subscriber stations that are located in said aircraft; and

    second transmitter means for transmitting said amplified received ground-based cellular signals and said control signals, exchanged from control channels on said received ground-based cellular signals to control channels on non-terrestrial cellular control channels, to said non-terrestrial cell sites.
