ABSTRACT:
The call admission control method provides guaranteed bandwidth connections in a mobile telecommunication networks (10) that have varying topology and dynamic capacities. Method (100) provides a systematic way to decide when to admit connection requests in a low-earth or medium-earth orbit based satellite telecommunication system (10). A call admission controller, located in a ground control station (40) receives a connection request from an earth station (50) that may be forwarded from a satellite (21) in a constellation (20) of satellites. The call admission controller segments a call holding time into a sequence of time segments and determines whether a path exists through the network (10) that has the required minimum bandwidth for each of the time segments. If such a path exists, the connection request is admitted and the call goes through. Otherwise, the call is denied and communication is blocked.
