METHOD, SYSTEM AND EQUIPMENT FOR IMPLEMENTING USSD SERVICE IN CDMA NETWORK
First Claim
1. A method for implementing an Unstructured Supplementary Service Data, USSD, service in a Code Division Multiple Access, CDMA, network, comprising:
- a Mobile Switching Center, MSC, transmitting an origination request, ORREQ, message carrying a user identification and a USSD access code to a Service Control Point, SCP, according to a queried mobile intelligent subscription information of a Mobile Station, MS, when receiving a call request carrying the USSD access code transmitted by the MS;
the SCP starting up a USSD service operation process according to the USSD access code carried in the received ORREQ message, determining an operation type code of a current step according to the user identification and the USSD access code, and performing a corresponding operation according to the operation type code of the current step;
the SCP constructing short message content associated with the operation type code of the current step, and transmitting the constructed short message content and a short message type identification to a Short Message Service Center, SMSC; and
the SMSC transmitting the short message content to the MS by way of a flash message indicated by the short message type identification.

Abstract
The present invention provides a method for implementing an Unstructured Supplementary Service Data (USSD) service in a Code Division Multiple Access (CDMA) network, which is implemented based on a mobile intelligent network service and a flash message service. A Mobile Switching Center (MSC) triggers the mobile intelligent network service, a Service Control Point (SCP) determines an operation type code of the current step according to a user identification and a USSD access code and performs a corresponding operation, and at the same time constructs short message content associated with the operation type code of the current step, and transmits the short message content to a Mobile Station (MS) by way of the flash message. The present invention also correspondingly provides a system and device for implementing a USSD service in a CDMA network. By providing an operation prompt, the present invention realizes real-time message interaction, and reduces user'"'"'s misoperation effectively.
