Tekelec leads Diameter signaling controller market

Tools

Tekelec leads the market for Diameter signaling controllers used to handle data signaling for mobile devices, according to a new report from Infonetics Research.

Tekelec has a strong position with an installed base of signaling system number 7 (SS7) customers and a leading position in the policy market.

Deployments of 4G LTE networks and the explosion of mobile broadband will fuel a doubling of the Diameter signaling controller market this year, the research firm predicted. Global revenue from Diameter signaling controllers jumped over 900 percent year-over-year in 2012, according to Infonetics data.

Diameter is one of the two signal protocols that handles most of the communications in IP multimedia subsystem networks; the other one is SIP. Diameter handles the data signaling for mobile devices, while SIP handles message signaling for VoIP and video conferencing, according to a white paper by Sonus Networks.

"On the back of explosive growth in 2012, the Diameter signaling controller market is set to double this year as operators across the globe continue to build out LTE networks and as mobile broadband usage soars. As more and more operators deploy LTE and Diameter traffic grows, the requirements for signaling control--both within an operator's own network and between operators--also increase, making Diameter signaling controllers a necessity," observed Diane Myers, principal analyst for VoIP, unified communications and IMS at Infonetics.

Smartphones and tablets are driving the demand for Diameter signaling controllers. When these devices access an application, download data, or roam, they generate a flood of signaling messages in the core network. As sales of these devices continue to grow, the need for Diameter signaling controllers will grow apace.
