Abstract
The 4G network is becoming commercially large-scale worldwide, and the industry has begun research on fifth-generation (5G) mobile
technologies. All this will increase the variety of multimedia services, especially for over-the-Top (OTT) services. OTT services have
already gained great popularity and contributed to a large consumption of traffic, which offers a load on operators. Management solu-
tion QoE for traditional multimedia services obsolete, which creates new problems in the aspects of the management of yo for suppli-
ers of services. This article discusses the main models that contribute to improving the quality of OTT services. The main parameter
for quality assessment was chosen QoE-Quality of Experience. An analysis was made of a number of factors that directly affect the
assessment of QoE. The second part of the article deals with models that can provide the necessary level of quality for OTT services.
These models were divided into three groups: traffic-based models, application-based models, and speed-based models. The main task
of the study is to find optimal solutions to ensure the quality of OTT services.
Keywords: 
OTT Services, QoE, QoS, MOS, quality models.
