The present invention discloses a system and method for implementing prepaid data services in a mobile communication network. In this system, a Data service Access Control Point (DACP), which is used for fulfilling price confirmation function and fee application function for data services, is added between a Service Control Point (SCP) storing prepaid account information of subscribers and a Prepaid Server/Content of Process Gateway (PPS/CP GW) used for data service charging. In the method of the present invention, by means of the interaction among a Packet Data Service Note (PDSN), a Home Authentication Authorization and Accounting (HAAA) server, the PPS/CP GW, the DACP and the SCP, the SCP deducts the fees from the prepaid account, and the PDSN controls the subscriber to utilize data service according to the fees deducted by the SCP. With the present invention, the subscriber can make prepayment for a data service by a prepaid voice account, which facilitates data service extension of mobile network operators and provides convenient data services for the subscribers.
A system for implementing prepaid data services in a mobile communication network, comprising a Radio Network (RN), a Packet Data Service Node (PDSN), a Home Authentication Authorization and Accounting (HAAA) server, a Prepaid Server (PPS)/Content Provider Gateway (CP GW), a Mobile Switching Center (MSC) and a Service Control Point (SCP), the RN further comprising a Base Station Controller (BSC)/Base Transceiver Station (BTS) and a Packet Control Function (PCF) module for data services, the BSC/BTS being connected to both the MSC and the PCF module, the MSC being connected to the SCP by means of a No. 7 signaling network, the PCF module being connected to the PDSN, the PDSN being connected to the HAAA via an IP network and the HAAA being connected to the PPS/CP GW, which is characterized in that this system further comprises a Data service Access Control Point (DACP) for fulfilling price confirmation function and fee application function for data services, the DACP being connected to both the PPS/CP GW and the SCP.
A method for implementing prepaid data services in a mobile communication network, the communication network comprising a SCP storing account information of subscribers as well as a PDSN, a HAAA and a PPS/CP GW which cooperate to fulfill data service access and charging, the method comprising:
