Abstract (in Japanese) (See Japanese page) 
(in English) A huge number of calls will be generated as a means of confirming the safety and communicating with the police, fire department, and so on in an emergency such as an earthquake or a fire. Therefore congestion occurs and it is difficult to connect in the local telephone network. As countermeasures against congestion, in order to increase the number of calls accommodated in an emergency in a circuit switched network, the trunk reservation control method for reserving some lines exclusively for priority calls used by public institutions,
and the holding time control method for general calls have been proposed. Its effectiveness was also shown. However, with these controls, the call loss probability of general calls is high, so that it is necessary to further reduce the call loss probability. In this paper,we propose a trunk reservation control method with allowing call waiting to reduce the call blocking probability. In comparison with the conventional method without waiting queue, our proposed method with waiting queue decreased the call loss probability for general calls while keeping the call loss probability for emergency calls low.
