In recent years,OTT voice and new service applications developed rapidly. Network operators launch VoLTE voice in response to OTT voice,but whether VoLTE has more advantages and can provide differentiated services is an issues for attention. It firstly presents the architecture of VoLTE and the key technologies for optimization,researches the measurement method of speech quality and the main factors influencing voice. It compares the VoLTE voice and OTT voice on MOS,cal establishing delay,traffic occupation.
