The present invention provides a method for implementing unstructured supplementary service data (USSD) service in a code division multiple access (CDMA) network, which is enabled based on mobile intelligent network service and flash message service. A mobile switching center (MSC) triggers the mobile intelligent network service; a service control point (SCP) determines the operation type code of the current step according to a user identifier and USSD access code, performs corresponding operations, and at the same time constructs short message contents associated with the operation type code of the current step; and the short message contents are sent to a mobile station (MS) by means of flash message. The present invention also correspondingly provides a system and equipment for implementing USSD service in a CDMA network. By providing an operation prompt, the present invention enables real-time message exchange, and reduces user's misoperation effectively. |
