Abstract (in Japanese) (See Japanese page) 
(in English) We have proposed a novel Call Admission Control (CAC) to maximize total user satisfaction in a heterogeneous traffic network and showed the effectiveness of our CAC by using optimal-threshold from numerical analysis. This CAC assumed that only such selfish users exist in the network. However, we need to consider the possibility that some cooperative users exist who would agree to reduce his requested bandwidth in order to improve another user's QoS/QoE. Under this assumption, the conventional CAC may not be optimal control. Moreover, if there are cooperative users in the network, we need some controls that encourage such user cooperation. However, these ``encourage'' controls have not yet have proposed. Therefore in this paper, we propose a novel CAC for cooperative user by using queueing theory. Moreover, numerical analyses show the effectiveness of our proposed CAC.
