Build Highly-Reliable SDM for Orange Romania


Orange is one of the leading Multi-national Telecom Operator in the world which owns many branches in Europe, Africa, etc. Orange Romania is the largest mobile operator in Romania, providing voice, data and Internet services based on GSM/UMTS network. With the quick development of mobile data services and fierce competition from mobile market, Orange Romania faces the following challenges:

  • Poor reliability of existing HLR: Frequent breaking down results in a lot of complaints, which greatly impacts on the service deployment.
  • Difficult to evolve to LTE: Hardware must be replaced, which wastes huge investment.
  • High CAPEX/OPEX: User data is distributed in different network nodes, and all the nodes must be deployed independently.

Orange has to solve above problems to achieve sustainable development and improve the competence for the future..
