Abstract
A satellite communication system (1110) provides geographic protocol conversion for message delivery between communication transceivers (1118, 1118') operating within at least two geographic areas (1116, 1116'). The satellite based communication system (1110) comprises a first communication transceiver (1118) which provides two-way message delivery within a first radiotelephone network (1114) located within at least a first geographic area (1116), the two-way message being encoded in a first predetermined message transmission protocol. The first communication transceiver (1118) further enables two-way message delivery with a communication satellite (1120), the message also being encoded in the first predetermined message transmission protocol. The communication satellite (1120) comprises a satellite transceiver (1312, 1328, 1310), for enabling the two-way delivery of the message encoded in the first predetermined message transmission protocol with the first communication transceiver (1118), and a protocol converter (1314) for converting the message encoded in the first predetermined message transmission protocol into a message encoded in a second predetermined message transmission protocol. The satellite transceiver (1312, 1328, 1310) further enables two-way delivery of the message encoded in the second predetermined message transmission protocol with at least a second communication transceiver (1118') operating within a second geographic area (1116').
