dc.description.abstract網路的興起對人類的活動產生了重大變革,網際網路電話(VoIP:Voice Over IP)的應用也將成為電信變革的推動元素,藉由VoIP人們的溝通不僅只有聲音,而是同時夾帶了更多的訊息與服務。近年來世界上主要的電信設備與服務提供者均開始嚴肅看待VoIP系統。技術標準制定組織(例如IETF及ITU-T)也開始制定新一代的網際網路電信通信協定、例如,IETF制定了MGCP。 儘管目前在VOIP系列標準方面的研究繁多,然而本篇論文的目的是以實作的角度進行研究,提出一套IP PBX交換機採用MGCP多媒體通信標準協定來設計。本論文中所提出IP PBX交換機的設計方法是以MGCP架構中所提出的通話代理人(Call Agent)和閘道控制器如下1.局端存取閘道控制器(AGW)、2.局端幹線閘道控制器(TGW )、3.住戶端閘道控制器(RGW)所組成,並且利用MGCP傳輸信令做為相互傳遞訊息,以建構IP PBX交換機。有關IP PBX交換機系統模擬實作部份、我們採用Microsoft Visual C++的MFC (Microsoft Foundation Classes)作為模擬開發工具,同時也開發電腦視窗圖形介面操做環境,使的整體通話服務流程訊息可以記錄下來以利MGCP訊息追蹤。藉此協助初學者來了解什麼是IP PBX交換機以及什麼是MGCP進而了解什麼是VOIP。zh_TW
dc.description.abstractIn this thesis,We discuss about IP PBX(Internet Protocol Private Branch Exchange)research topic. The IP PBX is based on MGCP(Media Gateway Control Protocol)used for controlling the gateways from external call control elements called media gateway controllers or call agents. A gateway is a network element that provides conversion between the audio signals carried on telephone circuits and data packets carried over the Internet or over other packet networks. MGCP allows call signaling control and processing intelligence in call agents or media gateway controllers. Gateways are expected to execute commands send by call agents or media gateway controllers. In our IP PBX implementation, We use MFC ( Microsoft Foundation Classes ) and C++ language to develop simulation tools. Moreover we develop a suite of computer windows graphical user interface for User friendly operation and understanding what is the IP PBX and the MGCP message flowen_US
