摘要： 针对互联网存在的实时服务集成问题，提出基于会话初始化协议(SIP)的异构实时服务集成平台，利用SIP URI对实时服务进行编址，并将其封装为接口统一的原子服务，采用服务注册和应用层路由的方式实现原子服务的调用，以P2P方式进行实时信息传输，确保系统的可扩展性，通过实现原型系统——公众交通出行服务系统，验证了该平台的可行性。

Abstract: Aiming at the problems of integration of real-time services in Internet, an heterogeneous real-time services integrated platform based on Session Initiation Protocol(SIP) is proposed, in which, real-time services are assigned SIP URI address and encapsulated into atomic services with uniform interface. Atomic services are invocated by service-register and application-layer-routing mechanisms. Considering scalability of the platform, real-time information is transferred by P2P method. By implementing the prototype system, the public traffic guide system, the feasibility of this platform is proved.
