Tekelec Enables Policy Control, Authentication and Charging in IMS Networks at Plugfest 6

Event Simulated Two Separate IMS Networks Across Several Continents

MORRISVILLE, NC--(Marketwire - February 25, 2009) - Tekelec (NASDAQ: TKLC), the network signaling, mobile messaging and performance management company, achieved interoperability with two IP multimedia subsystem (IMS) networks at the NGN/IMS Forum Plugfest 6, demonstrating advanced calling scenarios between multiple operator networks for the first time. The test event, held Jan. 12-16, 2009 at the University of New Hampshire InterOperability Lab (UNH IOL) in Durham, N.H., brought 11 participating vendors to create networks supporting up to 250,000 user sessions.

Tekelec's EAGLE® XG Call Session Control Function (CSCF), which provides core session initiation protocol (SIP) signaling and control within IMS networks, successfully tested with home subscriber servers (HSS), user equipment (UE), an offline charging system, an instant messaging application server and other CSCFs. The Tekelec EAGLE XG CSCF demonstrated the session flows required for IMS adoption by completing roaming of local subscribers to foreign networks and roaming of foreign subscribers to local networks.

Tekelec validated the EAGLE XG CSCF session flows with an instant messaging application server in various 3rd Generation Partnership Project (3GPP) roaming scenarios, and its secure authentication and key agreement (AKA) procedures. AKA requires complex interaction between equipment, CSCFs and the HSS, and must be vetted as part of a reliable IMS deployment.

"Each Plugfest takes IMS a step further, and shows how operators can evolve from next-generation networks (NGNs) to an IMS architecture," said Ron de Lange, executive vice president at Tekelec. "Tekelec's EAGLE XG CSCF provides the cost-effective scalability, flexibility and reliability to grow with service providers' network needs and manage the complexities of new technologies, resources and applications."

Tekelec's EAGLE XG CSCF bridges existing and new services in next-generation networks (NGNs), hybrid networks and IMS scenarios, providing a common signaling and session control layer in all domains. The application separates the transport, control and application layers to allow operators to reuse common components such as presence and location and run a wide range of converged services across any access network.

Plugfest 6 participants set up the two simulated IMS networks in one and a half days and tested user equipment, application servers, service creation and robustness. The event was the first Plugfest to simultaneously achieve policy control, charging and the wide support of IP applications. Specific testing included complex call flows involving multi-vendor equipment in a single domain, inter and multi-domain configurations, and off-line billing scenarios.
