從過去嚴厲的災害經驗像颱風,地震,洪水等,暴露出目前基於分時多工電路交換架構(TDM)的救難管理中心通信系統,無法處理分別來自災民遭受災害與一般大眾所需要的救難服務。因此本論文提出基於IMS網路通信架構之救難管理中心,使能提供各種基於IP的多媒體服務,如遠距視訊監控,即時的語音、影像和消息,定位服務…等。所提出之IMS網路通信架構最大的好處是能在固網線路毀損和停電等狀況之下嚴重天然災害損壞時,更有效率的恢復緊急就難通信服務。
From past experiences with severe disasters like typhoon, earthquake and flooding, it shows that concurrent TDM based communication system of emergency management agency could not handle the coming demands from public and refugee. This thesis proposes IMS network architecture for emergency management agency, which could access IP based multimedia services with remote surveillance, instant voice, video and message, location service...etc. The most benefit of the proposed IMS network architecture for emergency management agency could recover emergency communication service more efficiently under serious damages from landline broken down and electric power outage after natural disasters.
