Infonetics whitepaper examines the Diameter use cases operators need to plan for in IMS networks

CAMPBELL, CA--(Marketwired - October 30, 2014) - A new white paper by technology market research firm Infonetics Research examines the key Diameter use cases operators need to consider when planning for IP multimedia subsystem (IMS).

The white paper, Four Diameter Use Cases for Operators to Consider when Planning for IMS, is written by Infonetics analyst Diane Myers and explores how IMS networks introduce unique challenges into the Diameter signaling infrastructure.

"The growth of IMS around voice over LTE (VoLTE) deployments brings new challenges and opportunities related to Diameter and, ultimately, Diameter signaling controllers," notes Diane Myers, principal analyst for VoIP, UC, and IMS at Infonetics Research. "When configured correctly, Diameter can enhance customer experience by ensuring quality of service in VoLTE calls, video sessions, and enhanced messaging."


  • Operators in North America and Asia Pacific are beginning to launch VoLTE, with over 30 commercial VoLTE networks and 51 million VoLTE subscribers expected by the end of 2014
  • The number of VoLTE networks and subscribers will accelerate in 2015 and beyond
  • The scaling of IMS networks to manage VoLTE traffic will create challenges for Diameter signaling
  • By managing Diameter traffic, Diameter signaling controllers (DSCs) play an important role in ensuring a high-quality experience for services running over IMS networks
  • The four use cases that represent opportunities for DSCs and for which operators need to consider in planning for IMS are 1) session binding, 2) charging, 3) subscription location function, and 4) monetizing assets

Topics in Infonetics' 7-page Diameter white paper include an overview of Diameter; why and how VoLTE is driving IMS network expansion; a VoLTE subscriber forecast; the role that Diameter signaling controllers (DSCs) play in ensuring high quality service over IMS networks; and an examination of four use cases for DSCs, with illustrations.
