Bulgarian mobile operator m:tel has chosen Nokia Siemens Networks (NSN) to expand and upgrade its GSM network and enable customized services for its subscribers.

As part of the contract, NSN will expand m:tel’s GSM radio network and mobile softswitching core network, and ensure roll-out through professional implementation services.

The company said that it will also provide its Service Assurance Solution, to give m:tel a real-time view of user activity and service usage to enable problem detection and the introduction of new services.

In addition, NSN’s browsing gateway is expected to provide m:tel customers with access to advanced data services, and an extension of the charge@once prepaid charging platform.

Predrag Culibrk, CEO of m:tel, said: “Nokia Siemens Networks’ range of solutions will give us the timely customer insights to launch personalised services and deliver superior experience that will lead to increased usage. We are very confident that the network upgrade will help us maintain our strong market position by not only keeping existing customers but also attracting new ones.”

Dietmar Appeltauer, head of Central East Europe of Nokia Siemens Networks, said: “As end-users become more demanding, service providers can turn this challenge into an opportunity by offering differentiated services based on subscriber needs and preferences. Our mission is to enable operators such as m:tel to raise the bar on customer experience. We are building on our long term partnership with m:tel – which dates back to 1999 – to support it with best-in-class solutions customised to its business needs.”
