LTE Diameter Signaling Growth

Signaling volumes on 4G LTE networks will grow at twice the rate of mobile data traffic through 2017, according to new research from Oracle.

As a refresher, the Diameter protocol is an authentication, authorization, and accounting protocol defined by the 3rd Generation Partnership Project (3GPP) for HSPA+, LTE, and IMS. It's an important Service Provider Information Technology (SPIT) protocol as operators look to create and manage new personalized services over 4G LTE, including voice-over LTE (VoLTE). (See: Diameter Matters.)

Oracle Corp. (Nasdaq: ORCL), via its acquisition of Tekelec, is forecasting that worldwide LTE Diameter signaling traffic will increase at a 140 percent compound annual growth rate (CAGR), from 1.2 million messages per second (MPS) in 2012 to nearly 99 million MPS by 2017.

Network policy is the main contributor to signaling volumes, and, by 2017, will account for 62 percent of the signaling volumes, Oracle says. Every new personalized mobile data plan, mobile ad, M2M service, or content partnership will also drive up the numbers.

Check out the following infographic in which Oracle lays out the future of LTE Diameter signaling across the globe. And, read up on the topic below.

    Re: chatty apps Oracle reminded me that there are two kinds of signaling traffic. So, chatty apps, while a problem, affect a different part of the network. Here's their clarification:

    "There are two different signaling technologies at play in these networks. The "chatty" applications themselves pose a separate problem in the Radio Access Network (RAN). The signaling in this part of the network is different than the Diameter signaling in the core. Chatty apps are definitely an issue being addressed by the industry, but does not impact the Diameter portion of the network."

    chatty apps It's interesting that personalized services will spur so much Diameter signaling growth. It's also troubling, since operators are banking on personalized services to differentiate LTE and eke more revenues from it. They have control over the services they build, but are OTT providers doing anything to minimize signaling traffic? Should they care how chatty their app is?
