【摘要】：云計算的發(fā)展受到全球各國政府和企業(yè)高度重視,成為全球信息通信技術產(chǎn)業(yè)界公認的發(fā)展重點。同時,云計算帶來了第三次信息改革浪潮,徹底改變了人們使用IT服務的方式,降低了社會信息化門檻,具有廣闊的商業(yè)前景。但云計算的發(fā)展也面臨著諸多挑戰(zhàn),特別是在云計算服務訪問方式和云服務接口標準方面,限制了公共云計算服務的發(fā)展。云計算服務訪問方式主要基于Web服務模式,缺少完整的信令體系機制,不能有效的支持相關的定價、計費及內(nèi)容服務訪問控制等機制并缺乏統(tǒng)一的云計算服務接口標準。目前在通信領域,IMS體系的應用和服務在總體上仍處于初級階段并發(fā)展緩慢,電信運營商也缺少新穎的通信體驗增值業(yè)務提供給用戶。但是IMS體系結構具有開放和國際標準的信令控制體系,不僅對用戶進行完善的身份認證,還對用戶進行授權和計費管理。同時,IMS還具有網(wǎng)絡服務質(zhì)量保證,可提供高質(zhì)量的IMS服務。根據(jù)以上研究,本文設計了一種將IMS體系與云服務相結合的體系架構。本文主要研究的內(nèi)容和取得的成果是：第一,本論文在對IMS體系與云服務研究的基礎上設計了一種基于IMS的云服務訪問控制體系,包括客戶端、云服務通知功能、云配置功能、云會話控制功能、云會話交互部分。第二,論文根據(jù)RFC3261與RfC4566中相關的規(guī)定,對SIP與SDP做了相應的擴展,用于支持提供云服務資源的相關業(yè)務的媒體傳輸交互。第三,本文根據(jù)IMS信令過程,設計了云服務訪問控制體系的IMS信令過程,包括用戶注冊、用戶訂閱與計費。最后,基于開源的Openstack搭建了云服務平臺,同時基于開源的Kamailio搭建SIP服務器,實現(xiàn)原型系統(tǒng)測試,驗證了本文設計的基于IMS的云服務訪問控制體系具有合理性與可行性,并證明本文設計的體系結構可以支持云服務資源的相關業(yè)務。
[Abstract]:The development of cloud computing has been attached great importance by governments and enterprises all over the world. At the same time, cloud computing has brought the third wave of information reform, completely changed the way people use IT services, lowered the threshold of social information, and has broad commercial prospects. However, the development of cloud computing also faces a lot of challenges, especially in the access mode of cloud computing services and cloud service interface standards, which limits the development of public cloud computing services. Cloud computing service access mode is mainly based on Web service mode, lack of complete signaling system mechanism, can not effectively support related pricing, billing and content service access control mechanisms and lack of unified cloud computing service interface standards. At present, the application and service of IMS system in the field of communication is still in the primary stage and developing slowly, and the telecom operators also lack the new value-added service of the communication experience to provide to the users. However, the IMS architecture has an open and international standard signaling control system, which not only provides perfect authentication for users, but also provides authorization and billing management for users. At the same time, IMS also has network quality of service assurance, can provide high-quality IMS services. Based on the above research, this paper designs an architecture that combines IMS architecture with cloud services. The main contents and achievements of this paper are as follows: first, this paper designs a cloud service access control system based on IMS based on the research of IMS system and cloud service, including client, cloud service notification function, cloud configuration function. Cloud session control, cloud session interaction. Secondly, according to the relevant rules of RFC3261 and RfC4566, this paper extends SIP and SDP to support the media transmission interaction of related services providing cloud service resources. Thirdly, according to the IMS signaling process, this paper designs the IMS signaling process of the cloud service access control system, including user registration, subscriber subscription and billing. Finally, the cloud service platform is built based on open source Openstack and the SIP server is built based on open source Kamailio. The prototype system testing is realized, which verifies the rationality and feasibility of the cloud service access control system designed in this paper based on IMS. It is proved that the architecture designed in this paper can support the related services of cloud service resources.
