What is GMLC (Gateway Mobile Location Center )?

The Gateway Mobile Location Centre (GMLC) contains usefulness needed to help location-based service (LBS). The GMLC is the first node an external LBS client gets to in a GSM, UMTS. The GMLC should initially figure out which Serving Mobile Switching Centre (MSC) is dealing with the UE at the time the LCS request is made. It initially recognizes the MSC required by making a request to the HLR.
