The Centralized User Data Base on the Ericsson Blade Server provides a single point of access and administration to the subscriber data. The node is based on a Distributed Cluster Architecture which guarantees high capacity with an optimal footprint and real-time availability.

Offering many benefits

Ericsson Centralized User Database (CUDB) 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.

CUDB 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 Lightweight Directory Access Protocol (LDAP).

Ericsson CUDB delivers a host of benefits:

  • high performance – 150 million subscribers per CUDB system
  • low power consumption ~ 4kW for one cabinet
  • high availability: 1+1 or 1+1+1 configuration
  • compliance with 3GPP standard, anduse of open protocols
  • fewer DB nodes reduces total cost of ownership
  • the same, single platform – Ericsson Blade Server – as the rest of UDC elements
  • future-proof investment and long product lifecycle
  • common user-centric data modelingsupports many Ericsson and non-Ericsson applications
  • supports integration of new applications
  • enables new business opportunities, such as M2M and data monetization.

Many proof-points

Ericsson CUDB has proven multi-vendor references and proven high-subscriber capacity on live systems. To date, 59 contracts have been signedin 42 countries on all continents in which Ericsson CUBD is in use, including multiple types of integrated Front Ends. That represents a capacity of more than 800 million contracted subscribers.
