Abstract
We propose a threshold configuration and holding time limitation for general telephone calls under trunk reservation control in emergency situations. Our proposed method aims to accept more general calls while required emergency calls are still accepted. With our method, the threshold is configured in consideration of the ratio of traffic intensities which are estimated in advance. Computer simulation with a queueing system model of a telephone exchange showed that the general call-blocking rate was much lower than that without threshold relaxation or trunk reservation, while the emergency call-blocking rate was reduced to almost zero unless the sum of estimated traffic intensity was nearly equal to the number of lines. Moreover, we confirmed that the threshold was appropriately configured by using the proposed method, from the comparison between the result of the proposed method and that obtained by using the fixed value of a threshold.
