What Is a Location Manager?

Location management refers to the way a call is routed to a random mobile user to track changes in the user's location. In the existing second-generation digital mobile communication system, the location management uses two layers of databases, namely the home location register (HLR) and the visited location register (VLR). Location management includes two main tasks: Location Registration and Call Delivery. The procedure of location registration is to update the location database (HLR and VLR) and authenticate the mobile station if the real-time location information of the mobile station is known. The call transfer step is to locate the mobile station based on the location information available in the HLR and VLR in the case of a call to the mobile station. Location management involves network processing capabilities and network communication capabilities. ^[1]
