ABSTRACT
The number of users on mobile networks has continuously increased due to many attractive multimedia services. According to this reason, the service operators have to regularly improve their networks in order to retain the need of existing users and also attract the expectation of new users. Nowadays, the operators concern Quality of Experience (QoE) metric as the key performance index to evaluate the networks rather than Quality of Service (QoS) metric. However, the QoE metric is based on the viewpoints of domain's experiences which the experiences from users and networks might not be correlated. Therefore, in this paper, the demonstration of user-centric and network-centric viewpoints based on QoS measurement via Drive Tests on mobile networks is presented. The difference viewpoints of QoE derived from user-centric and QoS parameters achieved by network-centric have been investigated through mobile networks of top three operators in Thailand. The results indicate that only some QoS parameters can provide the same trend as QoE. It implies that the operators should set some parameters as the higher priority for improving the network quality if they want to satisfy the experience of users.
