Outline of Final Research Achievements

Both general calls and emergency calls are rushed to network when emergency events are happened such as disasters or incidents. Because many both calls are arrived at network and emergency calls are admitted preferentially, most of general call are not admitted and rejected.
This research realizes new general voice communications call admission control methods for emergency situation. Target networks includes fixed or cellular public switched telecommunication network, NGN, and the Internet. More general calls can be
admitted at networks by our proposed CAC methods, though the number of admitted emergency calls is not reduced.

Academic Significance and Societal Importance of the Research Achievements

非常時には,緊急通話はもちろんのこと,一般のユーザも現地の安否確認を行うなど通常より多くの重要な通話を行う可能性が高いため,緊急通話は必要数収容したうえで,可能な限り多くの一般通話も収容すべきである.
この,新しい思想のもと,一般通話に通話接続までの多少の待機を許容,さらには,安否確認などに最低限必要な時間までに一般通話の通話時間制限を設けることにより,緊急通話を確保しつつ,一般通話収容数の最大化も可能とする,非常時における音声通話確保を実現する新しい受付制御方式を,本研究では実現した.
