The Motorola Home Location Register (HLR) integrates the logical functions of the traditional HLR and the functionality of Authentication Centre (AUC). The HLR is the central database of the network. It stores the related data of all the mobile users within the controlled area of the HLR. The AUC stores authentication algorithms and ciphering keys to prevent illegal subscribers from accessing the system, thereby ensuring the mobile subscriber communication security over the radio interface. Its reliable performance, high capacity and smooth scaleability is the ideal solution for both small and large network configurations.
