System and method for providing an improved terrestrial subsystem for use in mobile satellite systems
First Claim
1. A method for using an auxiliary terrestrial component (ATC) and mobile satellite radio telephone system component (MSS) in a combination ATC/MSS system where the ATC coverage area overlaps in part the MSS coverage area, and the satellite radio telephone system comprises a communication satellite communicating on a series of frequency bands, where the method comprisesassigning a first frequency band from said series of frequency bands to the auxiliary terrestrial component;
- at the communications satellite, suppressing the use of the first frequency band;
allocating selected frequency bands other than the first frequency band to the mobile satellite radio telephone system component.

Abstract
A system or method is disclosed which employs filters on a satellite whose bandwidth is varied by ground command to restrict interference experienced by a satellite as an auxiliary terrestrial component (ATC) system is increased to a multiplicity of cities and markets. Thus there is provided a novel method and system which optimizes overall MSS and ATC traffic.

12. A system for using an auxiliary terrestrial component (ATC) and mobile satellite radio telephone system component (MSS) in a combination ATC/MSS system wherein the ATC coverage area overlaps in part MSS coverage area comprising:
- a communications satellite in communication with a gateway, said communication satellite having a series of communications return channels, each return channel comprising a separate frequency band, said satellite further having an filter having a series of settings, each filter setting suppressing satellite communication over a predetermined subset of said series of communication return channels, said system determining which of said filter settings is selected based on a command from a ground location or based on a predetermined time schedule.
