Abstract
A telecommunications system and method is disclosed for de-registering all Mobile Stations (MSs) at one time from a Gatekeeper of an H.323 system. In preferred embodiments, after an H.323 system shut down or upon receipt of a RESET message from a Home Location Register (HLR), the Mobile Switching Center (MSC) sends a single Unregistration Request (URQ) message to the Gatekeeper requesting de-registration of all of the MSs served by the MSC. The H.225 protocol for the URQ message is modified to indicate that all MSs associated with the MSC are to be de-registered. Alternatively, the modified URQ message can indicate that a certain group of MSs served by the MSC are to be de-registered.
