【正文】 碩士學(xué)位論文 多媒體系統(tǒng)中 基于號(hào)碼分析的呼叫路由 框架的設(shè)計(jì) 與實(shí)現(xiàn) 浙江大學(xué)碩士學(xué)位論文 摘要 i 摘要 目前，多媒體系統(tǒng)已經(jīng)應(yīng)用到各個(gè)重要場(chǎng)合，各種各樣的多媒體終端頻頻而出，從我們熟知的攝像機(jī)，監(jiān)視器，電視墻，到現(xiàn)在的高清 IPC 等等，這些終端的發(fā)展，使得多媒體系統(tǒng)的功能也越來(lái)越強(qiáng)大了。然而，現(xiàn)有的多媒體系統(tǒng)不是很完善，還有著許多需要改進(jìn)的地方 ,比如多媒體系統(tǒng)中服務(wù)器與終端之間的交互以及服務(wù)器本身之間的交互的恢復(fù)機(jī)制等。呼叫路由是多媒體系統(tǒng)的組成部分，旨在通過(guò)呼叫路由模塊來(lái)找到各個(gè)終端和服務(wù)器的地址，以便完成服務(wù)器和終 端之間的會(huì)話。本文基于對(duì)呼叫路由模塊的實(shí)現(xiàn)，分別從多媒體系統(tǒng)的組網(wǎng)、傳輸協(xié)議、數(shù)據(jù)庫(kù)等方面對(duì)多媒體系統(tǒng)進(jìn)行分析，指出了多媒體系統(tǒng)的一些需要改進(jìn)的地方和改進(jìn)的方案。同時(shí)，本文為多媒體系統(tǒng)提供了一個(gè)獨(dú)立的呼叫路由模塊并完成呼叫路由模塊數(shù)據(jù)庫(kù)的設(shè)計(jì)、編碼方案的設(shè)計(jì)和呼叫路由框架的設(shè)計(jì)。針對(duì)呼叫路由的框架，本文給出了呼叫路由模塊的幾個(gè)主要的數(shù)據(jù)結(jié)構(gòu)和函數(shù)接口，以便進(jìn)一步分析呼叫路由框架的實(shí)現(xiàn)過(guò)程。在呼叫路由模塊的實(shí)現(xiàn)中，本文參考了電話交換網(wǎng)絡(luò)中的號(hào)碼分析的應(yīng)用技術(shù)，為多媒體系統(tǒng)制訂了一套基本的編碼方案?；诒疚脑O(shè)計(jì) 的呼叫路由模塊，本文還為多媒體系統(tǒng)的業(yè)務(wù)的恢復(fù)提供了相關(guān)的實(shí)現(xiàn)策略并給出了多媒體系統(tǒng)中業(yè)務(wù)恢復(fù)的實(shí)例。 關(guān)鍵詞： 多媒體系統(tǒng) ， 終端，呼叫路由，號(hào)碼分析，會(huì)話 浙江大學(xué)碩士學(xué) 位論文 Abstract ii Abstract At present, IP Multimedia Operating System has been applied to many important occasions , various multimedia terminals e out more and more frequently as we know, from the camera, monitor, TV wall, to the present high definition IPC, etc, these terminals’ development makes the multimedia system being stronger and stronger. However, the existing multimedia system is not perfect enough, there are many areas in need of improvement in the multimedia system, such as the recovery mechanism of the interaction between servers and terminals in the multimedia system or the interaction between servers itself. Call routing is a ponent of the multimedia system, aims to find out addresses of the various terminals and servers from visiting call routing module in order to finish the sessions between servers and terminals. This article suggests some areas in need of improvement and the improvement plan by analyzing the multimedia system in the points of the multimedia system’s working, transfer protocol, database and so on which based on the realization of the call routing module. At the same time, this article provides a separate call routing module for multimedia system, pletes the design for call routing module’s database, coding scheme and framework. According to the framework of the call routing module, this paper gives several main data structures and interface functions in order to further analysis call routing framework’s implementation process. By learning the application technology of the telephone exchange work, this essay develops a set of basic coding scheme for multimedia system in the realization of the call routing module. Based on this design, this paper also provides some strategies for multimedia system’s business recovery and gives some business recovery examples.
