【摘要】：云计算的发展受到全球各国政府和企业高度重视,成为全球信息通信技术产业界公认的发展重点。同时,云计算带来了第三次信息改革浪潮,彻底改变了人们使用IT服务的方式,降低了社会信息化门槛,具有广阔的商业前景。但云计算的发展也面临着诸多挑战,特别是在云计算服务访问方式和云服务接口标准方面,限制了公共云计算服务的发展。云计算服务访问方式主要基于Web服务模式,缺少完整的信令体系机制,不能有效的支持相关的定价、计费及内容服务访问控制等机制并缺乏统一的云计算服务接口标准。目前在通信领域,IMS体系的应用和服务在总体上仍处于初级阶段并发展缓慢,电信运营商也缺少新颖的通信体验增值业务提供给用户。但是IMS体系结构具有开放和国际标准的信令控制体系,不仅对用户进行完善的身份认证,还对用户进行授权和计费管理。同时,IMS还具有网络服务质量保证,可提供高质量的IMS服务。根据以上研究,本文设计了一种将IMS体系与云服务相结合的体系架构。本文主要研究的内容和取得的成果是：第一,本论文在对IMS体系与云服务研究的基础上设计了一种基于IMS的云服务访问控制体系,包括客户端、云服务通知功能、云配置功能、云会话控制功能、云会话交互部分。第二,论文根据RFC3261与RfC4566中相关的规定,对SIP与SDP做了相应的扩展,用于支持提供云服务资源的相关业务的媒体传输交互。第三,本文根据IMS信令过程,设计了云服务访问控制体系的IMS信令过程,包括用户注册、用户订阅与计费。最后,基于开源的Openstack搭建了云服务平台,同时基于开源的Kamailio搭建SIP服务器,实现原型系统测试,验证了本文设计的基于IMS的云服务访问控制体系具有合理性与可行性,并证明本文设计的体系结构可以支持云服务资源的相关业务。
[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.
