ABSTRACT:
A radio telecommunication system includes a number of satellites in low earth orbits. Any number of subscriber units communicates with the satellites. A single subscriber unit communicates with a single satellite using electromagnetic signals so that a measurement processor can obtain Doppler component, propagation duration, and real time measurements of the signals. A location processor converts these measurements into a geographic location with respect to the earth. A service processor determines which qualifications to apply to communication services offered by the system. These qualifications are based on the subscriber unit's location. A call processor carries out the qualifications when requests to setup calls involving the subscriber unit are received by the system and during calls involving the subscriber unit.
