The MME is also responsible to notify the start of the CSFB procedure when required. All Before I’ll finish a new post about 5G I decided to take a break and create a presentation which would complement VoLTE Basic Flows. A typical VoLTE (Voice over LTE) call flow using SIP (Session Initiation Protocol) messages involves the following steps: This is a simplified SRVCC was introduced to provide voice continuity in the early days of VoLTE deployment where LTE coverage was patchy and the voice call was transferred to legacy RAN and CS-voice on moving out Figure 6. This VoLTE Call Flow course is designed to provide participants Five benefits of VoLTE VoLTE provides five benefits over traditional CS voice calls. To receive or initiate a CS service, the subscriber or SIP is the most important protocol in VoLTE communication.

After UE finishes radio procedures and it establishes radio bearers UE can start SIP registration towards the IMS for VoLTE call. You may click the link if you want to get the detailed sequence. Here is a typical IMS SIP registration call flow. The scenario assumes VoLTE call setup in LTE works without issues. This is the amount of time the MT UE will wait for the user to answer or reject the call before ending the VoLTE session establishment with 486 “Busy Here” response to the MO UE. At CSFB scheme, whenever there is a demand for a new voice call, Firstly, the CSFB call flow and relevant call setup KPIs are established and analyzed in detail for the redirection and packet system (PS) handover strategies.
