Abstract

See full text

The present invention is designed such that the communication quality of a currently connected normal call is deteriorated and the transmission of the normal call is delayed in a network when an emergent call is set. As a result, the required bandwidth of the emergent call is successfully reserved. Furthermore, the present invention is designed such that a deteriorated normal call is detoured to a detour circuit to improve the communication quality of the normal call. In the detouring process, one or more detour circuits are managed for each normal call so that the possibility of a successful detour to a detour circuit can be raised. Additionally, in the normal call detouring process, a plurality of detour circuits guarantee a normal call its communication quality even if a single detour circuit is not enough to meet the required bandwidth of a normal call.
