Software development: Custom HLR solution on top of service platform

Client and business need

MVNE in Western Europe looking to replace existing home location register (HLR) and authentication center (AuC) that were reaching end of support. The HLR component ought to be developed on top of Jain SLEE-based OpenCloud Rhino service delivery platform – the MVNE’s existing IN platform (previously deployed by R Systems).

  • Standard and custom HLR functionalities: multi-MSISDN and multi-IMSI allowing users to register multiple telephone numbers in the network, AuC capabilities – authenticating each SIM card that attempts to connect to the GSM network, and SIM management

The solution was integrated with the common subscriber profile repository (SPR), also deployed by R Systems engineers during the IN platform implementation.

Project highlights
