Market Demands

Telkomsel is the largest mobile carrier in Indonesia and gains over 60% market shares. Telkomsel serves more than 120 million mobile subscribers and cooperates with more than 300 international roaming partners to provide communication services for global subscribers.

Indonesia has many islands and is rich in tourism resources. However, Indonesia is located in the seismic belt, and frequent earthquakes are the biggest challenge for HLR reliability. HLRs on the live network do not support redundancy. Once natural disasters occur, services are interrupted, and even subscriber data is lost. With explosive development of mobile broadband, 3G networks cannot meet service development requirements, and LTE networks are mandatory in the future. HLRs on the live network do not support smooth evolution.

Communication market competitiveness becomes fiercer. Currently, 11 carriers in Indonesia serve 260 million subscribers. Telkomsel is confronted with great pressure. Subscriber data is available for the network and IT departments, and the data cannot be synchronized or shared. How to share data and exploit data value is Telkomsel's major concern.

Carrier Actions

Telkomsel used the SingleSDB to replace HLRs to address the problems of insufficient capacity, poor reliability, and difficulty of smooth evolution. In addition, the convergent HLR/HSS was deployed to implement unified subscriber data storage and management and unified service provisioning. This reduces TCO sharply, facilitates service deployment, and enhances carrier competitiveness. Telkomsel followed three steps.

HLR Resolves Problems

After over three years of joint efforts, Telkomsel's subscriber capacity reached more than 1 million. In addition to geographic redundancy for each province and each city, Telkomsel deployed triple-site data centers. This prevents subscriber data loss and service interruption during natural disasters. The SingleSDB solution facilitates smooth evolution to LTE using capacity expansion and license upgrade, which lays a solid foundation for LTE/VoLTE deployment and commercial use.

Subscriber Data Convergence

Telkomsel uses the Huawei SingleSDB solution, which provides unified data access interfaces. All IT systems access the database over unified interfaces. The number of HLRs decreases from over 100 to about 30, which reduces maintenance workload and implements network and IT data sharing.

Open Up Subscriber Data

As an innovative carrier, Telkomsel is exploiting subscriber data value. On condition of privacy data protection, Telkomsel opens up subscriber data to internal departments to provide personalized services and package recommendation. It also opens up subscriber data to third parties for accurate marketing and store location selection. This helps create a win-win situation and increases revenue.

Carrier Benefits

Since service launch in 2010, Telkomsel shared subscriber data within internal departments through network data and IT data convergence. No fault occurred in four years even if earthquakes occurred frequently. The TCO of subscriber data management decreases by 40%, and LTE service development speeds up. With the introduction of big data technologies, Telkomsel is creating a globally reliable subscriber data management platform and a vigorous ecological industry chain.
