Referring to FIG. 1, a wireless packet data network includes a terminal 101 of a mobile communication subscriber, a base station 103, a base station controller 105, a packet data serving node (PDSN) 109, and a proxy server ( It includes a proxy agent system (PAS) 115, a content provider server (CP) 117, an IP location provider (IPLS) 113, and an authentication server 111.                         

The base station 103 wirelessly transmits and receives data with the terminal 101 of the subscriber, and the base station controller 105 controls the operation of the base station 103.

The packet data serving node (PDSN) 109 is connected to the base station controller 105 through the LAN 107 and performs a call connection function based on a call connection request from the base station controller 105. In response to the call connection request from the terminal 101, an IP address is allocated.

The authentication server 111 includes a subscriber information database (not shown) of a wireless packet data network and performs authentication processing for a mobile communication subscriber.

The IP registration system (IPLS) 113 receives and registers a terminal identifier (MIN, MIN1) and an IP address of the terminal 101 from the packet data serving node (PDSN) 109.

The proxy server (PAS) 115 receives an HTTP page request from the call-connected terminal 101 and receives an HTTP_PHONE_NUMBER field from the HTTP header of the HTTP page request, that is, a terminal identifier (MIN, MIN2). Extract and save). The proxy server (PAS) 115 requests subscriber information for the extracted terminal identifier MIN2 to the authentication server 111 and receives subscriber information, and then provides a content provider server (CP: contents provider). Send the HTTP page request to 117).

The content provider server (CP) 117 responds to the HTTP page request received from the proxy server (PAS) 115 to the subscriber terminal 101 by HTTP response (HTTP Response). to provide. If the content is paid content, a content provider server (CP) 117 generates a charging record related to the information of the content with respect to the terminal identifier MIN2 included in the HTTP header. The generated billing record is billed later by a billing processing system (not shown) or the like and billed to the subscriber corresponding to MIN2.

When the content usage is complete and the call ends, the packet data serving node (PDSN) 109 creates a call related charging record for MIN1. The generated call-related billing record is billed later by a billing processing system (not shown) or the like and billed to the subscriber corresponding to MIN1.

2A and 2B are flowcharts illustrating a billing process for a conventional use of information.
