The present embodiments disclose a method and a service server for correlative processing of service information. The method includes receiving the service information; obtaining a correlative relation among information of each service; and performing a correlative processing on the service information according to the correlative relation. A correlative processing may be performed on the service messages of various applications based on IMS (IP Multimedia Subsystem) architecture, thereby the user experience of the service may be improved, and the service performance may be enhanced.
