Multichannel access protocol for satellite mobile data services

A complete set of access protocols for multiple satellite channels assigned for communications between mobile data terminals and fixed data hubs is proposed. The protocols address three types of data bearer services suitable for all types of applications. Multiple access for inbound interactive messages is based on contention for short messages and reservation for longer messages. An overview of the mobile satellite system (MSS) network configuration is given. Traffic characteristics and network connectivity for mobile data services are reviewed. The design of a complete set of multiple access protocols for different data services is described. The proposed protocols are simple to implement, and potentially provide efficient and timely access for both short and long messages.<
