Hello everyone, today let's talk about VONR voice calls recommended by 5G networks, and whether the terminal can use high-speed 5G data services synchronously during the call
Two common 5G voice solutions
There are two main types of voice solutions for 5G: EPS FB and VONR. The EPS FB mode is used in the NSA network architecture and in the case of networks where VONR is not deployedVONR is the ultimate solution for 5G SA voice (which has been commercialized on a large scale by major operators in 2022).
Comparison of user perception of VONR and EPS FB voice solutions:
1) Low latency of VONR voice access: Calls do not need to fall back to 4G, and the delay is reduced by 1 to 2 seconds
2) VONR airtime, high data experience rate: Calls do not need to fall back to 4G, and enjoy better data experience rate on 5G.
3) VONR voice*** voice MOS sub-call 4G voice call upgrade by 01~0.5 points.
Different 5G voice solutions are presented on the user's mobile phone
1) When making a VONR call, the call does not need to fall back to 4G, and the user can enjoy a better data experience rate on 5G, and the voice and data services are concurrently carried out on the 5G network, and the user's mobile phone displays the 5G icon.
2) However, when the EPS FB calls, the call needs to fall back to 4G, and the voice and data services are concurrently carried out on the 4G network, and the user's mobile phone displays the 4G icon.
In summary, 5G users do not need to drop back to 4G during VONR calls, and enjoy better data experience rates in 5G (data ** rates can also reach hundreds of Mbps), and voice and data services are concurrently carried out on 5G networks, which is significantly better than EPS FB mode.
