Ericsson Centralized User Data Base provides a single point of access and administration to the subscriber data. Based on Ericsson Blade Server and the distributed cluster architecture, which guarantees high capacity with an optimal footprint and real-time availability.
Ericsson Centralized User Database has the flexibility to accommodate subscription profiles for new applications and expanded services. Its linear scalability is guaranteed both in terms of capacity and throughput, without latency degradation.
It ensures data consistency and integrity, and provides redundancy mechanisms. The physical and logical distribution of data is transparent to any data user (HLR/AUC, application servers, BSS). Communication with data users is through standard LDAP (Lightweight Directory Access Protocol).
