US 7,769,151 B2 · System and method for implementing prepaid data services

Abstract

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.

Dependent claims

A system for implementing prepaid data service 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 being communicatively connected to both the MSC and the PDSN, the MSC being communicatively connected to the SCP, the PDSN being communicatively connected to the HAAA and the HAAA being communicatively connected to the PPS/CP GW, further comprising:

a Data service Access Control Point (DACP), communicatively connected to both the PPS/CP GW and the SCP, configured to:
send a fee request message to the SCP after receiving a charging request message to request fee distribution from the HAAA via the PPS/CP GW,
convert, after receiving a fee request response message from the SCP containing information about distributed fee, the information about the distributed fee into information for the PDSN to control data service utilization of the subscriber, and
send a charging request response message containing the information for the PDSN to control the data service utilization of the subscriber to the PDSN via the PPS/CP GW and the HAAA.
