As internet traffic increases, the problem that it should be efficiently accepted in to the existing voice network in the pending problem importantly to the existing communication corporations. The feature of next generation exchange network is made up of the form of integration network that connect data traffic(internet service. Etc) with the existing voice network and it can be showed with very diverse aspects according to the constitution time of network or the characteristics of business. The progress strategy that develop the existing circuit based communication network into packet-based communication network can be divided into two in a large scale according to the application position These are VoDSL application method(Technology that packetize access network) and softswitch technology application method(after packetizing relay network, packetizing that into the access network). In this paper, we will deduce the desirable technology that can construct packet-based next generation exchange networks in the structure of the existing communication network environment. We will perform the research on a device to offer the necessary core technique VoSDL service with realistic resolutions primarily.

사회와 산업이 발전함에 따라 국가적 재난재해는 다양성과 복잡성이 날로 증가하고 있고 그 피해규모 또한 대규모화되고 있는 추세이다. 최근 공공안전에 대한 국민들의 기대수준이 높아짐에 따라 고도화된 국가공공 재난안전무선통신 인프라의 필요성이 국내외적으로 대두되고 있으며 국가의 주도적인 역할이 요구되고 있는 상황이다. 본 고에서는 국내외 재난안전무선통신망의 구축 현황을 살펴보고, 우리나라의 차세대 재난안전무선통신망의 주요 요구기능과 그 요구기능에 적합할 것으로 예상되는 재난안전무선통신을 위한 후보 기술들을 알아보고자 한다.
