【摘要】：IMS(IP Multimedia Subsystem,IP 多媒体子系统)是 3GPP(3rd Generation Partnership Project,第三代合作伙伴)组织在R5版本中首次声明的能够支持IP多媒体业务的系统,它独立于接入模块,并且基于IP协议,采用了 SIP(Session Initiation Protocol,会话发起协议)来进行会话控制,将业务层和控制层相互分开,并提供一系列接口,提供终端之间的服务,为未来最有前景的移动控制平台。IMS可以把种类繁多的Internet业务融合到移动通信核心网中,给新业务的开发提供了方便。现在的研究已经将下一代网络(NGN)和IMS一体化,标准已经近乎成熟。现在各大网络设备商已经在全世界有许多成功部署的例子,并能服务于多个实际的商用网络。光纤通信系统是现代互联网时代的核心支撑系统之一,可以成为IMS最好的承载。首先概述了光纤通信系统关键技术的发展,结合这些挑战和机遇,分别从光纤通信的总体网络架构、城域网络技术、接入网络技术等多个方面来综合阐述光纤通信系统的发展趋势,以更有效地为未来的互联网、IMS网络提供强有力的技术支撑。IMS的即时消息业务(instant message,简称IM)和状态呈现业务(presence server,简称PS)可以说是所有业务的基础,是IMS部署阶段非常重要的两大业务,该论文利用JAVAEE技术深入的研究了这两大业务的服务器端的实现。主要有:首先仔细分析了 IMS网络业务层的状况,然后对IM业务和Presence业务在服务器端的主要流程作了大量的分析与概述,然后介绍了 JAVAEE技术的主要特点和其在服务器的主要作用。并依据两大业务的消息传递流程,用SIP Servlet结合一系列技术实现了 IM业务和Presence业务的核心功能。
[Abstract]:IMS(IP Multimedia Subsystem. IP Multimedia Subsystem is 3GPP 3rd Generation Partnership Project. The third Generation Partners, a system that was first declared in R5 to support IP multimedia services, is independent of access modules and based on IP protocols. SIP(Session Initiation protocol (session initiation protocol) is used to control the session, separating the business layer and the control layer from each other. And provide a series of interfaces to provide services between terminals, for the future of the most promising mobile control platform. IMS can integrate a wide variety of Internet services into the mobile communication core network. It provides convenience for the development of new services. Now the research has integrated the next generation network (NGN) and IMS. Standards are almost mature. Now there are many examples of successful deployment around the world by major network equipment providers. Optical fiber communication system is one of the core supporting systems in the modern Internet era. It can be the best carrier of IMS. Firstly, the development of the key technologies of optical fiber communication system is summarized. Combining with these challenges and opportunities, the overall network architecture of optical fiber communication and the metropolitan area network technology are respectively introduced. Access network technology and other aspects to comprehensively explain the development trend of optical fiber communication system in order to more effectively for the future of the Internet. IMS network provides strong technical support. IMS instant messaging service instant message. Imm) and presence service (PSS) are the basis of all services and are the two most important services in the IMS deployment phase. This paper makes use of the JAVAEE technology to deeply study the realization of the server side of the two services. The main contents are as follows: firstly, the condition of the IMS network service layer is analyzed carefully. Then the main processes of IM and Presence services in the server are analyzed and summarized. Then introduces the main characteristics of JAVAEE technology and its main role in the server, and according to the two major business messaging process. The core functions of IM service and Presence service are realized with SIP Servlet and a series of technologies.
