What is mobile volte? How to drive China Mobile volte?

VoLTE is a voice service based on IMS and an IP data transmission technology, which is completely different from 2G/3G. All its services are carried on the 4G network, and data and voice services can run under the same network.

Thanks to the high speed of 4G network, VoLTE can provide high-quality audio and video calls, and this call is re-developed based on 4G network, and the audio and video quality will be much better. Moreover, for operators, the utilization efficiency of VoLTE in the spectrum is much higher than before, which is more than four times that of GSM, and the network cost is reduced.

Opening the Volte service requires the hardware support of the mobile phone. If the mobile phone supports the Volte service, you can go to the local operator to open the Volte service of the mobile phone card, and some areas support the use of online business halls to open the Volte service.

Dominant characteristics

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 essentially different from 2G and 3G voice calls. VoLTE is an end-to-end voice solution based on all IP in 4G network. Compared with 2G and 3G voice calls, VoLTE can improve the voice quality by about 40% due to the adoption of high-resolution coding and decoding technology. VoLTE brings users a lower access delay (waiting time after dialing), which is 50% lower than that of 3G, about 2 seconds, compared with 6-7 seconds in the 2G era. In addition, under 2G and 3G, dropped calls sometimes occur, but the dropped call rate of VoLTE is close to zero.

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. Because for voice services, the spectrum utilization efficiency of LTE is far superior to the traditional system, reaching more than four times that of GSM.

Another value is to enhance the 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.
