“…Based on this definition, quality should be evaluated subjectively considering user context. Some studies have also been conducted on QoE for web access services on PCs [31], [32] and downloading services [33], [34], and the evaluation of tolerable waiting duration in cellular phone usage considering three factors: application classification, place of use, and degree of relaxation [35]. Some of the studies considered parameters other than the network QoS, such as price [36], [37] and usability [38].…”

SUMMARY The Technical Committee on Communication BehaviorEngineering addresses the research question "How do we construct a communication network system that includes users?". The growth in highly functional networks and terminals has brought about greater diversity in users' lifestyles and freed people from the restrictions of time and place. Under this situation, the similarities of human behavior cause traffic aggregation and generate new problems in terms of the stabilization of network service quality. This paper summarizes previous studies relevant to communication behavior from a multidisciplinary perspective and discusses the research approach adopted by the Technical Committee on Communication Behavior Engineering.

“…ITU-T Recommendation G.1030 [10] defines the procedure for subjective quality assessment of website access on PCs and presents experimental results from subjective assessments of different types of users. Some research has also been conducted on QoE for web access services on PCs [11], [12] and downloading services [13], [14]. Some of the studies considered parameters other than the network QoS, such as price [15], [16] and usability [17].…”

As mobile multimedia services expand, user behavior will become more diverse and the control of service quality from the user's perspective will become more important in service design. The quality of the network is one of the critical factors determining mobile service quality. However, this has mainly been evaluated in objective physical terms, such as delay reduction and bandwidth expansion. It is less common to use a human-centered design viewpoint when improving network performance. In this paper, we discuss ways to improve the quality of web services using time-fillers that actively address the human factors to improve the subjective quality of a mobile network. A field experiment was conducted, using a prototype. The results of the field experiment show that time-fillers can significantly decrease user dissatisfaction with waiting, but that this effect is strongly influenced by user preferences concerning content. Based on these results, we discuss the design requirements for effective use of time-fillers.

“…Utility is defined as degree of user's satisfaction, and a utility function is defined as a relation between service quality and utility. Ref [3] has proposed a radio agent, which allocates the bandwidth of wireless channel to users according to their utility for the latency time and the data size for wireless file download services. In video download services, however user's satisfaction depends on both the latency time and the video quality.…”

It is difficult to receive video download services in wireless environments. Some service management schemes to consume network resources effectively from the aspect of user's satisfaction (utility) are proposed. In video download services, user's satisfaction depends on both the latency time and the video quality. Some utility functions for the latency time or the video quality in video download service have been already measured. But these utility functions for video download services cannot be applied because users might become insensitive to the latency time when paying their attention to a video. In this paper, we firstly measure utility for the video quality and video download services by subjective assessments. Next, we newly propose a service management scheme to maximize utility for given throughput and show the effect of the proposed scheme applied to variable throughput with computer simulation.
