Mobile Networks' Analysis in Terms of QoS Performance Assessment

Abstrakt

Quality of service (QoS) assessment is one of the basic processes carried out by mobile network operators (MNOs) and regulators of the telecommunications market. Usually, professional companies carry out measurements for various country areas and use cases (scenarios). In this paper, we show exemplary measurement results carried out in drive tests in the vicinity of the Polish capital by a professional company. The measurement campaign included two MNOs and three use cases, i.e., voice calls, video live streaming from YouTube, and web browsing. Various parameters of the received signals and QoS metrics were recorded during the measurements, e.g., reference signal received power, signal-to-interference-plus-noise ratio, mean opinion score (MOS), video MOS, and throughput. One of the MNOs provides services using Universal Mobile Telecommunications Service (UMTS) and Long-Term Evolution (LTE) technologies, while another is based only on LTE technology. The presented results show that higher QoS metrics were obtained for the LTE network than one using UMTS/LTE technologies.
