What's the harm of volte calling?

Volte call itself is harmless, but there is still room for improvement in the use of this technology. The function of VoLTE is based on 4G channel, because the LTE network has not achieved seamless coverage, and the optimization has not kept up. VoLTE can't be used and can't make phone calls in places where the signal of 4G network is not good. VoLTE needs to be turned off again to make a phone call.

Advantages of volte calling:

1, technical advantages

The most direct feeling brought by VoLTE technology to 4G users is shorter connection waiting time, higher quality and more natural voice and video call effect. VoLTE is an end-to-end voice solution based on all IP in 4G network. Compared with 2G and 3G voice calls, the voice quality can be improved by about 40%. VoLTE also brings users lower access delay (waiting time after dialing).

2. Operators

For operators, the deployment of VoLTE means the evolution of mobile broadband voice. In the long run, this will bring two values to operators. First, improve the utilization rate of wireless spectrum and reduce the network cost.

3. User experience

VoLTE experience is obviously superior to traditional CS voice. First of all, the introduction of high-definition voice and video codec has significantly improved the communication quality; Secondly, the connection time of VoLTE is greatly shortened, and the test shows that VoLTE is more than half shorter than CS call. Thirdly, seamless integration with RCS can bring rich services.
