+ Home Location Register (HLRi) (2002 – 2003)
The HLRi implements the ETSI/3GPP specified functions for HLR (=home location register) and AC (= Authentication Center) in mobile GSM and UMTS networks. It is the data base where the current locations, subscriber parameters and security credentials of the mobile subscribers are permanently stored.
The HLR Innovation is based on multi-purpose continuous availability Siemens middleware termed @vantage, which is built from standard IT technology (e.g. UNIX, Java, XML). The HLRi has been designed to run as a stand-alone HLR/AC.
The project goal was migration of the successful SIEMENS HLR from the proprietary EWSD platform to a commercially available platform (SUN or SUN-compatible) and to cover all hardware and most of the basic software with OEM products and maintain the telco specific requirements for high performance and high availability.
