Understanding VoLTE Roaming for S8 Home-Routed and Local Breakout Architectures

Filed in LTE, Roaming by on December 15, 2015 0 Comments

VoLTE, or Voice over Long Term Evolution, is beginning to rapidly revolutionize voice service for mobile communications. But making the transition to this new technology involves a number of challenges, as complex connections are worked out, new equipment is installed and mobile devices are made with the necessary hardware. A particularly critical component is enabling VoLTE roaming, which requires testing, resolving and ensuring the quality of a number of new processes.

At Syniverse, we’ve been in the thick of helping operators navigate this transition, and in this post, we would like to explain an important concept related to VoLTE roaming – the difference between S8 home-routed and local breakout architecture. In the video below, my colleague Faron Achziger and I go over some of the most  important aspects of these two technologies, including which technology is the most prevalent now, what the challenges and advantages of each are, and how we see S8 home-routed and local breakout evolving in the near future.

Please check out our video to discover more about VoLTE roaming. And if you weren’t able to attend our VoLTE webinar last week, “Lessons Learned: Implementing VoLTE Roaming in Europe,” which featured John Wick, Senior Vice President and General Manager of Mobile Transaction Services at Syniverse, and special guest Keith Dyer, Founder and Editor of The Mobile Network, please check out part of the webinar recording and some of the slides.

As Senior Technology Manager of Next-Generation Solutions at Syniverse, Brian manages solutions for Syniverse’s IP Services Hub, a service-aware hub for VoLTE (Voice-over Long Term Evolution), ViLTE (Video-over LTE), and RCS (Rich Communication Services) roaming and interconnect over IPX (Internet Protocol Packet Exchange), and he also develops solutions for hosted IMS (Internet Protocol Multimedia Subsystem) for standards-based Wi-Fi calling. After joining Syniverse in 2005 as a part of the Research and Development team, Brian began working with IMS and next-generation messaging, leading the technical aspects of the Fixed Mobile Convergence Alliance (FMCA) global presence and IMS trials. He also played a key role in the early phases of Syniverse’s Advanced Messaging Hub and Wi-Fi Talk & Text solutions. Brian has been involved in RCS since 2009 and VoLTE since 2011, and he has attended a number of industry conferences and work groups. Recently he has been active in RCS interconnect and VoLTE roaming trials as a member of the VoLTE/RCS Interconnect and Roaming Trial Team (VRirTT). Brian holds a Master of Science in computer science and a Bachelor of Science in biology from the University of Tennessee.
