| 摘 要： | 提出了基于OSGi（Open Services Gateway Initiative）的满足IMS（IP Multimedia Subsystem）规范要求的SIP Agent的设计与实现。该SIP Agent使用实现OSGi规范的Equinox为核心框架,并结合JAIN-SIP作为底层协议栈,能够符合绝大部分的IMS应用。主要包括逻辑结构说明,主要模块的结构和关键技术设计,基于SIP Agent搭建呼叫信令流程来论证其可用性。基于论文所提出的SIP Agent构建的应用程序具有低耦合、高内聚、易扩展、高性能的特性,能够方便快捷地构建SIP相关的应用。

| Abstract: | This paper proposes the design and implementation of Sip Agent, which meet IMS(IP Multimedia Subsystem) specifications based on OSGi(Open Services Gateway Initiative). It uses the Equinox, which implements OSGi specification as the core framework, combined with JAIN-SIP, as the underlying protocol stack, and can meet most of the IMS application. This paper includes the explanation of the logical structure, the main module's structure, the introduction of key technology, and the development of a call procedure using Sip Agent, to prove its availability. The applications, which is built on Sip Agent presented in this paper, has low coupling, high cohesion, easily extensible, high-performance features, and it can build SIP-related application quickly and easily. |
