U.S. operator C Spire Wireless is deploying Tekelec’s Diameter Signaling Router (DSR) to deliver personalized services on its LTE network.

The DSR intelligently routes the policy, charging, roaming, authorization, authentication and mobility management messages that enable mobile data services. These messages communicate using the Diameter protocol.

Tekelec’s DSR will support subscribers’ personalized LTE experience by enabling C Spire to:

• Offer new and innovative LTE services. The DSR binds a subscriber’s mobile data activities – including browsing and voice over LTE (VoLTE) – to a single policy server. This allows C Spire to offer new tightly integrated VoLTE and data services.
• Manage Diameter signaling traffic. All of C Spire’s Diameter traffic will flow through the DSR, giving the operator a central nervous system to intelligently route messages across network elements. This reduces the risk of signaling overloads and balances network resources to reduce congestion, allowing subscribers maximum use of C Spire’s LTE capabilities.
• Secure the LTE network. The DSR provides a secure interconnection to partner networks, protecting private network and subscriber from third parties.

“An efficient, reliable network is critical for our customers to use mobile data when and how they want, at an affordable price,” said David Smith, vice president of Network Engineering for C Spire Wireless. “Tekelec’s Diameter Signaling Router is an essential element for C Spire to offer creative voice and data services for consumer and enterprise customers.”

Tekelec has 75 percent to 85 percent share of the Diameter signaling control market, according to industry analyst firm Exact Ventures, including eight North American mobile operators.

“C Spire rapidly rolled out LTE last year, and is architecting a New Diameter Network from the get go,” said Tekelec CTO Doug Suriano. “This allows C Spire to personalize broadband services for both consumers and enterprises.”
