T-Mobile USA has chosen Tekelec’s (News - Alert) Diameter Signaling Router (DSR) for the buildout of its high-speed LTE network, expected to launch in 2013.

The DSR provides T-Mobile (News - Alert) with a central control point to efficiently route policy, charging and subscriber messages. This is essential to generate revenue from mobile data services and manage signaling growth in the New Diameter Network.

With the DSR, Tekelec can cost-effectively scale the LTE (News - Alert) network. A centralized Diameter network eliminates the need to update all network elements when adding new equipment or when adding new roaming interconnections, thus controlling costs as the LTE network and interconnections grows.

In addition, the router intelligently directs Diameter messages to avoid signaling storms.

The DSR transmits signaling messages based on real-time network conditions. For example, the system avoids sending messages to congested equipment by spreading the signaling volume across multiple network elements such as charging systems, policy servers and subscriber databases. This eliminates ‘signaling storms’ which can cause congestion and service disruptions.

At present, Tekelec has 19 Diameter Signaling Router customers, including five Tier 1 LTE operators in North America.

According to Infonetics (News - Alert) Research, Tekelec is the “front runner” of the Diameter signaling control market. Market intelligence firm Exact Ventures, on the other hand, estimates that Tekelec has 75 percent to 85 percent share of the market.

“T-Mobile’s innovation and modernization of our 4G network encompasses the entire infrastructure – from the core out to 37,000 cell sites, providing subscribers with a fast and dependable 4G experience,” said Abdul Saad, senior vice president of network technology for T-Mobile USA. “Tekelec’s Diameter Signaling Router provides us with the network architecture and scalability we require in order to deliver innovative mobile data services that meet the needs of our customers today and in the future.”

According to Doug Suriano, CTO at Tekelec, “T-Mobile is stepping on the LTE accelerator to launch new services next year. By implementing a new LTE Diameter Network from the start, T-Mobile will be able to scale and rapidly add LTE subscribers, devices, applications and service tiers.”

The mobile broadband solutions company is expected to present and demonstrate strategies for operators to monetize mobile data at LTE Asia 2012 on September 17-19 in Singapore.

The Tekelec LTE Diameter Signaling Index is an industry first, intended to help business executives, network architects and engineers forecast Diameter signaling traffic growth.

Tekelec forecasts the Asia-Pacific region to lead the world in Diameter signaling by 2016.
