FIG. 5 is a flowchart illustrating an example of a procedure for integrating billing information in an integrated billing operation method using an integrated billing system according to the present invention.

As shown in FIG. 5, the wireless communication terminal 100 possessed by the user is allocated with a resource in association with a mobile switching center (MSC), and thereby has a data connection (PPP) with the packet data node server 300. (51).

At this time, when the authentication of the wireless communication terminal 100 is successful, the packet data node server 300 transmits a charging start data record (Start UDR) to a charging server 600 in an accounting request message and transmits the session. It is notified that this has started (52, 53).

When the set time elapses, the packet data node server 300 accumulates the service starting from the start time, that is, when the charging start data record (Start UDR) is carried in an accounting request message and transmitted. The interim settlement data record (interim UDR), which is the amount of usage, is loaded into the accounting request message and transmitted to the billing server 600 (54). At this time, as the predetermined time set as described above elapses, transmission of the service usage information accumulated for each cycle is continuously performed while the wireless communication terminal is connected to the call.

In this case, when the data connection between the wireless communication terminal 100 and the packet data node server 300 is released, the packet data node server 300 terminates the data session with the user, that is, the wireless communication terminal 100. The charging end data record (Stop UDR) provided to the user is loaded in an accounting request message (Accounting Request Message) and transmitted to the charging server 600 (55).

Then, the billing server 600 receives the billing end data record (Stop UDR) carried in the accounting request message (Accounting Request Message), generates billing information by integrating the billing information of the corresponding data session, and generates at this time One charging information is transmitted to the integrated charging information server 900 (56).

Here, the billing server 600 extracts information such as a session start time, end time, provided service amount, provided service type, and the like from a billing start data record, an intermediate settlement data record, and a billing end data record. The integrated data record is generated and transmitted to the integrated billing information server 900.

6 is a flowchart illustrating an example of a limit management procedure in an integrated billing operation method using an integrated billing system according to the present invention.

As shown in FIG. 6, the limit management procedure is a procedure for processing a billing data record received by the billing server 600, and if the wireless communication terminal 100 is a billing subscriber, the limit management module of the billing server 600 ( 650) to start the limit management by passing the billing information.

That is, the terminal 100 of the user interworkes with a MSC (wireless switching center) to allocate resources on a communication network, and establishes a data connection (PPP) with the packet data node server 300 using the allocated resources. When the authentication of the wireless communication terminal 100 is completed, the packet data node server 300 loads a charging start data record (Start UDR) in a counting request message and transmits it to the charging server 600. In this case, when the wireless communication terminal 100 is operated by the limit fee, the billing server 600 interoperates with the service control point 500 to obtain the service limit amount of the corresponding subscriber.

When the set time elapses, the packet data node server 300 accumulates from a start time, that is, a charge start data record (Start UDR) to the accounting request message and is transmitted. The interim settlement data record (interim UDR), which is a service usage amount, is loaded in an accounting request message and transmitted to the billing server 600. At this time, as the predetermined time set as described above elapses, transmission of the service usage information accumulated for each cycle is continuously performed while the wireless communication terminal is connected to the call.

Accordingly, the charging server 600 deducts from the service limit amount by using the provided service amount whenever a message of the interim UDR of the session is received (63).

In this case, when the specified time elapses, the billing server 600 performs an interim settlement on the limit amount in connection with the service control point even if the session is not terminated. That is, the intermediate settlement informs the service control point 500 of the amount of data service provided up to that point and receives a new limit amount (64).

Therefore, if the service limit amount is continuously deducted through the interim settlement data record (Interim UDR) and the limit amount is used up, the billing server 600 exceeds the limit to the subscriber with the service control point 500. The service is sent to the end request message, that is, the information indicating to end the service, that is, the charging end data record (Stop UDR). Then, the service control point 500 notifies the MSC to terminate the call, and the MSC terminates the radio connection with the terminal and releases the allocated call (65).

When the service of the subscriber is terminated, the service charge termination information provided so far is loaded into a counting request message (Accounting Request Message) and transmitted to the charging server 600.

Then, the billing server 600 receives the billing termination message and informs the service control point 500 of the amount of service provided to the subscriber, so that the service control point 500 correctly updates the limit DB of the subscriber. (66).

In addition, the charging server 600 integrates the charging information of the corresponding data session to generate one charging information and transmits it to the integrated charging information server (67).

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is not limited to the stated embodiments and the accompanying drawings, and it is common in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
