Geographic Forecasts

•North America: Diameter signaling traffic will rise to 15.9 million in 2016, for a 216 percent CAGR. North America will be the largest contributor to global Diameter traffic through 2015. •Asia-Pacific (APAC): Diameter signaling traffic will rise to 16.7 million MPS in 2016, for a 263 percent CAGR. APAC will lead the world in Diameter MPS starting in 2016. •Europe, Middle East & Africa (EMEA): Diameter signaling traffic will rise to 13.8 million MPS in 2016, for a 320 percent CAGR. •Caribbean & Latin America: Diameter signaling traffic will rise to nearly 540,000 MPS in 2016, for a 962 percent CAGR. A sharp rise in LTE subscribers is expected in the region beginning in 2013.

•Doug Suriano, chief technology officer, Tekelec: "Diameter signaling growth is more dramatic than mobile data traffic growth. The rise is steeper, the time to plan for it is shorter and there are no offload solutions like there are for data traffic. But here's the good news: service providers now have a way to forecast Diameter signaling traffic on their LTE networks. This is critical because an increase in Diameter signaling means an increase in personalized services, higher revenues, and happier customers." •Jim Hodges, senior analyst, Heavy Reading: "While a number of factors will drive an increase in Diameter signaling over the next five years, LTE subscriber growth will have a profound impact. As a result, operators are adopting a centralized Diameter routing architecture and utilizing more extensive forecasting tools to ensure they maximize the scalability potential and efficiency of their next-gen signaling networks." •Mike Thelander, CEO of Signals Research Group: "Unlike the ongoing 3G signaling storm which is being created by smartphone-based applications and social networking services, the eminent Diameter signaling phenomenon can also have positive implications in the form of new revenue-generating opportunities for service providers and differentiated service offerings for subscribers. The industry, however, first needs to fully understand and appreciate the Diameter signaling implications associated with various policy control and enforcement initiatives, new services, such as VoLTE and M2M, not to mention the underlying network architecture."

About Diameter

Diameter is the signaling protocol service providers use to deliver personalized services. It is essential for authorization, authentication, policy, charging, and mobility management. Diameter messages enable subscriber network access, secure interconnection with roaming and over-the-top application partners, accurate charging, and usage-based services.

Forecast Methodology

The Tekelec Diameter Signaling Index calculates LTE Diameter MPS based on assumptions relevant to LTE services such as third party LTE subscriber forecasts, subscriber usage, the number of active subscribers, the number of concurrent sessions, mobility busy hours, subscriber busy hours, policy sessions and online and offline charging interactions.

3GPP and GSM Association standards and documentation are used to establish Diameter traffic profiles based on service type. Assumptions are validated in Tekelec's Diameter Signaling Lab at the Morrisville, North Carolina Customer Experience Center.

This information is incorporated into the Tekelec Diameter Signaling Index Calculator™ available to service providers to forecast Diameter signaling traffic growth on LTE and 3G networks.
