BTC Group, the Bulgarian fixed and mobile communications group, will enhance the services offered to its subscribers by becoming the first operator in the country to provide Internet Protocol-based multimedia and voice experience.
Nokia Siemens Networks (NSN) is providing vivatel, BTC Group’s mobile operator with its IP Multimedia Subsystem (IMS) platform and mobile Voice over IP application server (NVS) for advanced and cost-effective convergent services.
With the NSN customer-optimized end-to-end solution, vivatel subscribers will enjoy a range of all-IP convergent services including mobile, fixed-line and Internet telephony services (voice, data and multimedia) with a single phone number, as well as broadband Internet access and a range of video applications, presence, interactive gaming and conference facilities.
“Our company has repeatedly proved its leadership in providing state-of-the-art services, and the entry into convergent IMS-based services is a natural thing,” says BTC Group Chief Commercial Officer, Alexander Dimitrov. “The solution from Nokia Siemens Networks will help us consolidate our leadership and strengthen our position to counteract cheap VoIP services, adding rich media communications on top of it.”
IP Multimedia subsystem is a part of the next-generation core network, which, according to NSN, allows operators to fully embrace the Internet by delivering services over all types of access, with flexible charging and seamless mobility.
Under the contract, vivatel also will be equipped with the mobile softswitch-based NSN VoIP Server and the Communication Suite, a rich call application for PCs that interoperates with mobile devices, for cost-effective VoIP telephone services. In addition, NSN also will provide network and service management, including profile management for provisioning new, converged services.
And in anticipation of the future growth of peer-to-peer (P2P) traffic resulting from new services, NSN also will supply data traffic control via its Flexi ISN solution, a flexible packet-core platform that can be used to manage bandwidth allocation for different applications, subscription and access types and to ensure fair use of networks resources, and quality and availability of services.
