For years operators have employed signaling system 7 (SS7) as the international, standardized protocol for call setup, mobility management, charging, and intelligent network applications. That’s all about to change. As operators migrate to all-IP networks, many of the functions performed by SS7 are being replaced by equivalent operations based on the Diameter protocol.

Diameter is a message-based, signaling protocol designed to provide authentication, authorization, and accounting (AAA) functions in IP-based networks. Third Generation Partnership Project (3GPP) has adopted Diameter as the primary signaling protocol for AAA, mobility management and policy and charging control (PCC) in all-IP, service-oriented architectures. The protocol was first introduced by the 3GPP in Release 5 for use in IMS networks. Initially, with releases 8 and 9 Diameter’s use was extended to LTE networks for numerous network functions and interfaces.
Why Diameter (NEW)
This webinar gives a short overview on why a Diameter signaling solution is important as service providers move to LTE.
Diameter Use Cases (NEW)
This webinar highlights four use cases that demonstrate how service providers can implement network and subscriber intelligence to monetize mobile broadband.
