The Diameter signaling protocol has taken center stage in the mobility world in the past few years. Used for activity coordination between Internet Protocol (IP) network elements such as policy servers, online charging systems and mobility gateways, Diameter serves a crucial function in mobility. And, as operators have migrated their networks to LTE, added new services and implemented more sophisticated policy use cases, signaling volumes are skyrocketing.
This LTE Diameter Signaling Index serves as a guide for network architects and engineers building Diameter networks where policy intelligently orchestrates the subscriber experience and Diameter signaling conducts communications among policy servers, charging systems, subscriber databases and mobility management functions.
