VoLTE Protocols and Signaling Training

VoLTE Protocols and Signaling Training is a technical level VoLTE covering VoLTE operation, protocols, VoLTE/SIP call flows, signaling and the SIP signaling messages in the  IMS architecture including VoLTE registration, VoLTE to VoLTE calls, VoLTE to 3GPP 2G/3G network calls, VoLTE to non-3GPP calls, and Interworking with the PSTN,  and emergency service calls.

Learn about: Architecture and protocols of Voice over LTE (VoLTE), IP-Multimedia Subsystem (IMS) Architecture and Protocols, VoLTE call setup and release, dedicated bearer setup, VoLTE interworking, Voice Call Continuity (VCC), Emergency Calls and  Location baaed Services.

Learning Objectives

Upon completion of completing of VoLTE Protocols and Signaling Training course, the attendees will be able to:

  • Illustarte VoLTEf features and network architecture
  • Explain the detailed of VoLTE call setup and related protocols and signaling
  • Describe the roles of IP-Multimedia Subsystem (IMS) protocols and signaling in VoLTE
  • Illustrate the VoLTE initialization, attach and call operation detials
  • Desdcribe the steps in Voice over LTE (VoLTE) Originating Call
  • Summarize VoLTE  Attach and Default Bearer Setup Messaging
  • Describe VoLTE QoS and security features and implemention options
  • Summarize traffic operations for UL and DL
  • Describe operation, protocols and singaling steps in SMS over IMS
  • Describe VoLTE secuity and protection features including Authentication, Integrity and Encryption
