Both of Quality of Service (QoS) and Quality of Experience (QoE) are defined to specify the degree of service quality. In some sense, QoE includes subjective evaluation from the users as an extension of QoS. Therefore feedback from QoE to QoS control might realize user-oriented resource allocation in network services. Utility functions are sometimes used to assign a bridging role between QoS and QoE. Although the user characteristic has variety, a single utility function was used in previous studies in most cases. Moreover the QoS control, i.e. the resource allocation, by making use of the utility functions are hardly studied yet. In this paper, multiple user types which have respective utility functions are considered. Respective utility functions are acquired from real experiments. Then a resource allocation method is proposed to reflect each user type satisfaction based on the utility functions. The simple case is studied and the resource allocation method is derived analytically.
