Length: 2 Days
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
