Extended data:

VOLTE is called Long Term Evolution Voice, which means the high-speed wireless communication standard for mobile phones and data terminals. Based on the IP Multimedia Subsystem (IMS) network, it uses special configuration files (defined by GSM Association in PRD IR.92) [1] for the control plane and media plane of voice service in LTE, so that voice service (control and media plane) can be transmitted as a data stream in LTE data bearing network without maintaining and relying on the traditional circuit-switched voice network. VoLTE's voice and data capacity is more than three times that of 3G UMTS and six times that of 2GSM. Because the VoLTE packet header is smaller than the unoptimized VoIP/LTE, it can also use the bandwidth more effectively.
