Abstract:
A cellular radio communication apparatus, operable both as a non-terrestrial cellular mobile subscriber station and a ground-based cellular mobile subscriber station, comprising:first means for generating a radio frequency communication signal at one of said radio frequencies allocated for ground-based cellular mobile subscriber stations and in a mode compatible with ground-based cellular communications to communicate with a ground-based cell of a cellular communication system; second means for generating a radio frequency communication signal at one of said radio frequencies allocated for ground-based cellular mobile subscriber stations and in a mode compatible with non-terrestrial cellular communications to communicate with a non-terrestrial cell of a cellular communication system; means for determining a present location of said cellular radio communication apparatus; means, responsive to said means for determining, for activating at least one of said first means for generating and said second means for generating to communicate with a corresponding cell of a cellular communication system; and means, responsive to receipt of subscriber data, for inserting said subscriber data into said radio frequency communication signal to create a composite radio frequency signal.
