Abstract

A mobile satellite radiotelephone system uses some of the capacity of a fixed satellite radiotelephone system in areas of congestion. Capacity sharing is obtained by providing at least one fixed retransmitting station in an area of overlap between the fixed and mobile satellite radiotelephone systems. The fixed retransmitting station retransmits communications between the fixed satellite radiotelephone system and at least one of the mobile radiotelephones in the vicinity thereof. The fixed retransmitting station coommunicates with the mobile radiotelephones using the mobile radiotelephone air interface, so that the communication is transparent to the mobile radiotelephones.

Description

field of invention [0001] This invention relates to radiotelephone systems and methods, and more particularly to satellite radiotelephone systems and methods. Background of the invention [0002] Satellite radiotelephone systems are being developed and deployed in many parts of the world. Satellite radiotelephone systems are often used in areas where rough terrain or sparsely populated areas make ordinary mobile radiotelephones or landline (wired) telephones impractical. The design and operation of satellite radiotelephone systems are well known to those skilled in the art and need not be described in detail here. Obviously, radiotelephone systems can be used for both voice and data communications, and radiotelephones can therefore include terminals such as PCS terminals. [0003] Satellite radiotelephone systems can be roughly divided into two categories: mobile satellite radiotelephone systems and fixed satellite radiotelephone systems. In both systems, one or more sate...
