This is an intermediate-level VoLTE Signaling and Operations Training course that builds on participants’ knowledge of VoLTE and the IMS architecture. Participants analyze real-world VoLTE/SIP logs collected from commercial VoLTE networks using drive test equipment. The IMS infrastructure is simulated using Open IMS, so participants also analyze SIP signaling messages in the IMS domain. This VoLTE Signaling and Operations Training course uses a scenario-based approach, allowing participants to step through key scenarios such as VoLTE registration, VoLTE to VoLTE calls, and Interworking with the PSTN/3G and emergency calls. Log analysis is emphasized where logs are available. Other topics are explored using detailed message flow diagrams.

  • Sketch the VoLTE network architecture
  • Walk through the following scenarios and identify the SIP messages and related parameters for:
  1. VoLTE registration
  2. VoLTE to VoLTE call setup and release
  3. VoLTE to PSTN interworking
  4. Voice Call Continuity (if applicable)
  5. Emergency Calls
  • Step through the dedicated bearer setup during VoLTE call initiation
  • Elaborate on Voice Call Continuity features to interwork with erstwhile RAN technologies
  • Identify the LTE RAN enhancements required to support VoLTE
  • We can adapt this VoLTE Signaling and Operations Training course to your group’s background and work requirements at little to no added cost.
  • If you are familiar with some aspects of this VoLTE Signaling and Operations course, we can omit or shorten their discussion.
  • We can adjust the emphasis placed on the various topics or build the VoLTE Signaling and Operations course around the mix of technologies of interest to you (including technologies other than those included in this outline).
  • If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the VoLTE Signaling and Operations course in a manner understandable to lay audiences.
