Communication satellite load balancing system and method
First Claim
1. A method of controlling system capacity in a satellite-based cellular telecommunication system having a plurality of communication satellites orbiting above a commonly-covered region of the earth and a plurality of mobile cellular stations which are capable of transmissions with at least a plurality of said orbiting communication satellites during at least some interval of time, said commonly-covered region having a plurality of grids, each of said grids having a plurality of mobile cellular stations, comprising the steps of:
- determining a power utilization factor for each of said communication satellites required to supply one of said transmissions to each of a plurality of said grids; and
assigning each of said plurality of grids to at least one of said orbiting communication satellites to handle communications between said plurality of grids and said orbiting communications satellite, wherein said assignments minimize the maximum single-satellite power required for said satellite-based cellular telecommunications system to supply transmissions to each of said plurality of grids.

Abstract
A method of controlling communication satellite system capacity in a satellite-based cellular telecommunication system where two or more communication satellites provide coverage of a service region. Communication satellites are assigned to mobile cellular stations in a manner designed to minimize the maximum single-satellite power that is required for the communication satellites collectively to supply a specified number of transmissions to the service region. The service region may be divided into grids, where each grid is characterized by a number which is proportional to the average number of active mobile cellular stations. This information, in conjunction with a power utilization factor associated with each satellite/grid pair, is used to determine the assignments of the communication satellites to the mobile cellular stations.
