Abstract
A point-to-multipoint (PTM) communication system ( ) includes a cellular radio infrastructure ( ) having base stations ( ) implemented in satellites ( ) placed in low earth orbits ( ). PTM subscriber radios ( ) share common cellular radio infrastructure ( ) multipoint channels ( ) to engage in a common PTM communication session while the cellular radio infrastructure ( ) also conveys point-to-point communications. A group control computer ( ) constructs a channel list ( ) which is downloaded to PTM subscriber radios ( ). The channel list ( ) identifies multipoint channels ( ) and indicates when and where the channels ( ) are active. Without emitting transmissions to the cellular radio infrastructure ( ), PTM subscriber radios ( ) autonomously switch to new multipoint channels ( ) in response to their current time and location and the channel list ( ).
