The present invention relates to the network architecture and billing method of the packet switch data service of the CDMA Intelligent Network (IN) user. Because the CDMA mobile switch uses the 3G1x packet switch data service, the billing of the service bypasses the MSC calling control layer, the billing can only be implemented by the PCF. In the PCF, there are only two billing methods: by amount of data method and the post service method. The non-real time post billing methods are not suitable for the IN prepaid users. Thus, the present invention illustrates new network architecture and billing method of the packet switch data service. The billing interface (PCF-SCP) is provided between the PCF and the SCP. The billing interface transfers at least three messages between the PCF and the SCP, to implement the real time or periodic billing for packet switch data service.
