Abstract
A telecommunications system and method is disclosed which allows for optimization of calls using satellite resources by moving a Mobile Station's (MSs) registration to an optimum Mobile Switching Center/Visitor Location Register (MSC/VLR) within the area visible to the satellite. This can be accomplished by sending the Called Party Number (CPN) to a Call Optimization Server (COS), which performs a pre-analysis on the CPN to determine the optimum MSC/VLR, e.g., the MSC/VLR with the closest connection to the called subscriber. Thereafter, the address of the optimum MSC/VLR is returned to the MS, which can then register with the indicated MSC/VLR and send a SETUP message to the new MSC/VLR to complete the call. This optimization can also be performed for mobile terminated calls, from either another Mobile Station or from a caller within the Public Switched Telephone Network (PSTN) (wireline network).
