Abstract
A communication system for multimedia having a plurality of mobile and fixed terminals. The system links terrestrial communication systems together through a network of non-geostationary satellites. The terrestrial communication systems include fixed location, mobile, and portable communication systems. The satellites communicate with a communication protocol similar to terrestrial communication protocols. This reduces protocol conversion. The source and destination addressing uses static terrestrial cells for the uplink and the downlink. Terminal data stream is segmented into communication packets at the terrestrial gateway based on the uplink satellite's determination of system parameters. The non-geostationary satellites route the communication packets the satellites. The control satellite dynamically balances up-links and down-links in the terrestrial areas with over-lapping satellite coverage.
