【摘要】：多媒體視頻監(jiān)控業(yè)務(wù)雖然已經(jīng)是成熟的互聯(lián)網(wǎng)業(yè)務(wù),但由于缺乏信令概念和相應(yīng)體系,會(huì)話控制及相關(guān)的用戶認(rèn)證、授權(quán)和計(jì)費(fèi)都比較困難,導(dǎo)致開展信息服務(wù)的技術(shù)門檻過高,難以通過網(wǎng)絡(luò)帶給人們生活的便利,多媒體視頻監(jiān)控業(yè)務(wù)的“商業(yè)化”和“公共服務(wù)”功能受到很多限制。多媒體視頻監(jiān)控業(yè)務(wù)作為典型的IP多媒體子系統(tǒng)(IPMultimedia Subsystem, IMS)業(yè)務(wù)是新一代通信業(yè)務(wù)發(fā)展的重要領(lǐng)域,它既滿足IMS網(wǎng)絡(luò)業(yè)務(wù)的要求,同時(shí)又滿足運(yùn)營(yíng)商對(duì)電信業(yè)務(wù)可運(yùn)營(yíng)、可管理的要求。要視頻監(jiān)控成為信息服務(wù)產(chǎn)品“電子商務(wù)”中重要的一部分,視頻監(jiān)控需要通過IMS應(yīng)用服務(wù)器與網(wǎng)絡(luò)中其它功能整合,進(jìn)一步加入IMS信令機(jī)制,整合為IMS新業(yè)務(wù),可有效支撐視頻監(jiān)控業(yè)務(wù)的商業(yè)運(yùn)營(yíng),同時(shí)也實(shí)現(xiàn)IMS業(yè)務(wù)的集成創(chuàng)新。因此作為IMS業(yè)務(wù)支撐環(huán)境主體的應(yīng)用服務(wù)器在IMS業(yè)務(wù)中至關(guān)重要。本文設(shè)計(jì)實(shí)現(xiàn)了一種支持多媒體視頻監(jiān)控的IMS應(yīng)用服務(wù)器,為了充分融合IMS業(yè)務(wù)架構(gòu),IMS應(yīng)用服務(wù)器中各模塊設(shè)計(jì)完全符合多媒體業(yè)務(wù)的信令邏輯規(guī)范和標(biāo)準(zhǔn),采用B2BUA (Back-to-Back User Agent,背靠背用戶代理)的應(yīng)用服務(wù)器操作模式,便于業(yè)務(wù)的管控,還對(duì)媒體服務(wù)器的分發(fā)進(jìn)行了負(fù)載均衡調(diào)整,提升了用戶體驗(yàn)質(zhì)量。本文主要研究?jī)?nèi)容和取得的成果是：1)研究并設(shè)計(jì)了支持多媒體視頻監(jiān)控的IMS應(yīng)用服務(wù)器的功能架構(gòu)和典型業(yè)務(wù)邏輯流程,并實(shí)現(xiàn)了業(yè)務(wù)的關(guān)鍵信令流程；2)提出了一種擴(kuò)展會(huì)話描述協(xié)議的方法,用于支持多媒體業(yè)務(wù)會(huì)話協(xié)商中的媒體傳輸交互,并設(shè)計(jì)了相關(guān)的信令消息流程；3)提出了一種采用B2BUA的應(yīng)用服務(wù)器操作模式的IMS應(yīng)用服務(wù)器的設(shè)計(jì)方案,設(shè)計(jì)實(shí)現(xiàn)了支持多媒體視頻監(jiān)控業(yè)務(wù)的IMS應(yīng)用服務(wù)器內(nèi)部功能模塊；4)設(shè)計(jì)了媒體服務(wù)器分發(fā)實(shí)體,并采用動(dòng)態(tài)權(quán)值調(diào)整策略對(duì)媒體服務(wù)器進(jìn)行負(fù)載均衡的分發(fā)調(diào)整。測(cè)試結(jié)果表明,本文設(shè)計(jì)實(shí)現(xiàn)的IMS應(yīng)用服務(wù)器各項(xiàng)功能和運(yùn)行效果滿足了設(shè)計(jì)要求,可以穩(wěn)定地支持多媒體視頻監(jiān)控業(yè)務(wù)的開展,并交付遼寧移動(dòng)公司進(jìn)行了應(yīng)用示范。
[Abstract]:Although the multimedia video surveillance service is a mature Internet service, it is difficult for the lack of signaling concept and corresponding system, session control and related user authentication, authorization and billing. The technical threshold for information services is too high to bring convenience to people's lives through the Internet. The functions of "commercialization" and "public service" of multimedia video surveillance services are restricted by many limitations. As a typical IP multimedia subsystem, multimedia video surveillance services (IMSs) are important areas for the development of new generation communication services. It not only meets the requirement of IMS network service, but also meets the requirement that telecom service can be operated and managed. Video surveillance needs to integrate with other functions in the network through IMS application server, further join IMS signaling mechanism, and integrate into new IMS service, which can effectively support the commercial operation of video surveillance service. At the same time, it also realizes the integration innovation of IMS service. Therefore, the application server, which is the mainstay of IMS service supporting environment, is very important in IMS service. This paper designs and implements a kind of IMS application server which supports multimedia video surveillance. In order to fully integrate the design of modules in IMS application server, which conforms to the signalling logic specification and standard of multimedia service, B2BUA Back-to-back User Agent (back-to-back user Agent) is adopted to operate the application server, which is convenient for service management and control. The distribution of media servers has also been adjusted for load balancing, The main research content and achievement of this paper is: 1) the functional structure and typical business logic flow of IMS application server supporting multimedia video surveillance are studied and designed. A method of extending the session description protocol is proposed to support the media transmission interaction in multimedia service session negotiation. A design scheme of IMS application server based on B2BUA application server operation mode is proposed. The internal function module of IMS application server which supports multimedia video surveillance service is designed and implemented. (4) the media server distribution entity is designed. The dynamic weight adjustment strategy is used to adjust the load balance of the media server. The test results show that the functions and running effects of the IMS application server designed and implemented in this paper meet the requirements of the design. Can support the development of multimedia video surveillance business, and delivered to Liaoning Mobile Company for application demonstration.
