How does Telecom Open Volte?

Send "ktVoLTE" code to 1000 1 by SMS, then reply "y", and then turn on the VoLTE function in the phone settings.

It is based on the IP Multimedia Subsystem (IMS) network, and uses special configuration files (defined by GSM Association in PRDIR.92) for the control plane and media plane of voice service over LTE.

This enables voice services (control and media level) to be transmitted as data streams in LTE data-bearing networks without maintaining and relying on traditional circuit-switched voice networks.

Advantages and characteristics of VoLTE

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.

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.

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.
