Abstract
A telecommunications system and method is disclosed for managing congestion in the Home Location Register (HLR). At regular intervals or in response to a registration message associated with a Mobile Station (MS) registration request, the HLR can transmit the current load conditions in the HLR to one or more Mobile Switching Centers (MSC's) within the area served by the HLR. In response, the MSC's can use this load information to reduce the registration intensity in order to protect the HLR from congestion. Each MSC can include one or more HLR load thresholds, and if the current load level in the HLR is above one of these thresholds, the MSC can reduce the number of registration messages sent to the HLR by a certain amount.
