Abstract (in Japanese) (See Japanese page) 
(in English) VoIP begins to enable the interconnection in heterogeneous wireless media communication system. At the same time, the construction of the infrastructure of the heterogeneous wireless media communication system becomes a problem, too. To guarantee the quality of a real-time communication in heterogeneous wireless media system, this paper proposes the codec selection agent and its selection algorithm. In the system, agents control voice and video codec according to network and user's situations. The telephone speech quality of IP phone service to the network load and the received power is experimentally evaluated, and the selection of the codec and its effect are considered.
