VARIABLE BANDWIDTH SATELLITE COMMUNICATION TECHNIQUE

摘要

PROBLEM TO BE SOLVED: To provide variable bandwidth satellite communication techniques that maintain a high bandwidth efficiency and high service quality. SOLUTION: Multiple bandwidth requestors 201, a bandwidth manager 401 and a forward link from the bandwidth manager to the bandwidth requestor 410 are used to allocate bandwidth in a return link beam 210. The uplink bandwidth allocation is preferably decided based on the information to be transmitted provided by the user ADPE(automatic data processing equipment) 300 and overall system data loading. The preferred method exercised by the bandwidth manager 401 allocates bandwidth on the return link 210 to individual user terminals 200 in either a minimal rate required for the protocol being exercised 213, a committed information rate 214 required for the services being requested, or a constitutional share rate 214 that allows maximum transfer of data from the user terminal 200 to the gateway 400.
