More and more research has been focused on improving system properties of the original systems. In this paper, to resolve system expansion, data sharing and redundant problems of China railway existing information systems, a new heterogeneous system integration method based on flexible service is proposed. Based on autonomous decentralized system and correlative technologies, this paper proposes information flexibility descending field (IFDF) to support service-based system integrating. Firstly, the definition and functional structure of autonomous integration node (AIN)is described, AIN is the key node to implement systems integration. Secondly, this paper describes the flexible and rigid information formats, implements node communication mechanism to complete service navigation autonomously. Lastly, China railway heterogeneous information integration system (CHIS) model based on flexible service is given out. Experimental result demonstrates that this service-based model has a better responsive ability than server-based system model, at the same time system architecture implemented by IFDF and AIN assures that new system has a better on-line ability.
