SIP Servlet应用路由机制

摘要

In the system of 3G IMS, SIP application server is the main provider for enriching the content of service.JCP(Java Community Process)defines SIP Servlet Standard to simplify the process and improve the efficiency, which also offers Java application programming interface(API)for SIP application server. The mechanism of application router for SIP Servlet is an important module for rapidly customizing 3G services and it is a hotspot of studying nowadays. In order to implement complex services by composing applications flexibly, this article based on analyzing the application router for SIP Servlet puts forward and realizes a method, which makes use of SailfinV2 standard container to design the custom defined application router, and also expounds how to employ the method according to an instance. Finally, the experiment result reflects the high efficiency and flexibility of newly increased mechanism of application router.%3G IMS系统中,SIP应用服务器是丰富业务内容的主要提供者之一.为了简化开发流程,提高开发效率,JCP(Java Community Process)组织定义了SIP Servlet标准,为SIP应用服务器开发提供了Java应用编程接口.SIP Servlet应用路由机制是快速定制3G业务的重要组件,成为了当前研究的热点之一.为了自由地组合应用程序完成复杂的业务,本文在分析SIP Servlet默认应用路由的基础上,提出并实现了利用SailfinV2标准容器设计自定义应用路由的方法,通过一个实例详细阐述了使用该方法的具体步骤,实验结果表明新增的应用路由机制具有较强的灵活性和高效性.
