LTE is a broadband wireless communication standard, including a voice service that is upgraded to 5 G, with the core network technology. In recent years Voice over Internet Protocol (VoIP) became more accessible to customers because of the increasing competence of Internet services and the development of voice call applications. According to its increased capacity, data rates, and lower latency, LTE meets the demand for high data rates for many mobile users. Voice over LTE (VoLTE) is the Cellular network system for transmitting voice over TCP. To network operators or system manufacturers, the quality of service (QoS) assessment of VoLTE coverage is essential. This article presents the evaluation analysis of video quality QoS Key Performance Induction (KPI) and the POLQA Mean Audio Performance Rating in the VoLTE application. This measurement can be done for various video quality analysis display formats and packeting mode. Audio quality analysis in the VoLTE call is done by measuring the statistical and distribution information for Uplink and Downlink Mean opinion score (MOS). MOS for video quality assessment (Average) is conducted. Graphical analyses of the video rating distributions verify the calculated QoS KPIs for video calls. The calculation analysis finishes with the verification of the option in VoLTE Call for video codec screen formats and packeting mode. Audio performance can be defined as the audio quality of the test device by the visual display of Downlink and Uplink. Such knowledge will help software manufacturers on the IMS stack to enhance video quality and identify audio output systems on MOS basis. In this, research discuss VoLTE and Video over LTE (ViLTE) performance issues. In the ITRI VoLTE test environment, we analyse VoLTE voice quality in measurement experiments. We will also pose ViLTE Call with a check in a FET industrial mobile network in multimode or multi-band interworking. Our study provides information on the quality of the VoLTE and ViLTE services for operators. |
