STUDY AND ANALYSIS ASSESSMENT QUALITY OF SERVICE OF SOME MOBILE NETWORK SERVICE PROVIDERS IN VIETNAM

Abstract

With the increasing number of users using smart mobile devices, the types of services will also be diverse. At that time, the service quality (QoS - Quality of Service) of telecommunication service providers must be drastically improved to be able to compete with each other. However, with the mobile network characteristics, controlling and improving QoS service becomes a difficult problem. The objective of the paper is to analyze and assess the parameters that affect QoS in three cases when using mobile networks: walking, stationary, and traveling by motorbike. The results show that the QoS evaluation parameters of uplink, downlink, delay and Jitter are greatly affected and have significant changes. The movement speed makes these parameters most of the way down, which explains the move away from Base Transceiver Station (BTS) and the technology of transferring between these signal transceiver stations of suppliers. Mobile services are not fully optimized yet.
