Optimization Ideas for 5G Voice EPS Fallback Calling Process
There are two ways to implement voice calls in 5G networks,one is the EPS Fallback method,and the other is the target VoNR non fallback method.Due to the fact that the EPS Fallback mode needs to be dropped back to the 4G network first,the call connection delay is about 1 second slower than the VoNR mode.It proposes an idea for optimizing the EPS Fallback calling process.Through network side upgrades and modifications,the EPS Fallback calling delay is ultimately consistent with the VoNR calling delay.
