Abstract: The present invention discloses a method and a system for coordinating services provided by different service providers, the core concept of which lies in that: after obtaining a service request from a sending end, a Service Adaptor/Dispatcher Center (SADC) transfers the service request into a form supported by a receiving end according to related service data of the receiving end and delivers the service request to the receiving end; and after the receiving end provides the corresponding service result according to the service request, the SADC sends the service result to the sending end. With the method or system, the services provided to a mobile user by different service providers may be coordinated and the existing Parlay components may be configured in the OSE developed in recent years. In addition, the method or system may provide a uniform interface to an upper-layer application.
