Nokia, Telemar Oi trials fixed-mobile convergence solutions for Brazil

Nokia has signed a Memorandum of Understanding (MoU) with Brazil's Telemar Oi. Trials are to begin of Nokia's fixed-mobile convergence solutions.

Nokia's solutions are intended to lever Telemar's current fixed network into creating a converged packet-based domain for fixed and mobile services. Telemar operates the largest fixed network in South America, with around 15 million subscribers, as well as the Oi branded mobile network, which currently caters to around 8 million subscribers.

The trial employs an end-to-end solution for unified core and converged access networks, as well as Nokia terminals providing multimedia and VoIP services for both mobile and fixed customers. The Nokia unified core includes the Nokia IP Multimedia Subsystem (IMS; for voice calls and multimedia services), the Nokia VoIP Server, and the Nokia MSC Server System (MSS). The agreement also includes testing of the Nokia Unlicensed Mobile Access (UMA) solution for extending the potential of fixed broadband networks.

The Nokia IMS solution provides the service machinery for enriching communications in converging fixed and mobile networks. It enables SIP-based multimedia services, eg, video sharing and push to talk, in addition to voice services for fixed, cellular and multi-radio terminals, as well as for PCs.

The Nokia VoIP Server, a key part of the Nokia IMS solution, supports the convergence of legacy voice and VoIP communications by allowing Telemar Oi to offer mobile telephony services, such as Caller ID and SMS, to VoIP customers.

The Nokia MSC Server, a 3GPP Release 4 based voice solution, is currently deployed in Telemar Oi's commercial mobile network, as part of an earlier contract. Nokia has been the main GSM network supplier to Oi since 2001.

Telemar Oi is part of Telemar Group, Brazil's largest private company. The Group holds the concession to operate the local fixed telecommunication network and the authority offers wireless services with Oi in Region I, which includes 16 northern, north-eastern and south-eastern states.

Besides this, the company acts across the whole of the country, providing data communication and long distance services since June 2002, when it received authorization to act throughout Brazil with code 31, which was launched regionally in 1999. Telemar Group has established a single brand in Internet and mobile segments with its own ISP Oi Internet, launched in February 2005.
