Abstract

A system for providing billing information of a wireless data communication service includes an Inter-Working function (IWF) for, if a data call is received, assigning an Internet protocol (IP) address to a mobile communication terminal that has sent the data call and transmitting the assigned IP address to a billing server; the billing server for, if the IP address is received, searching for billing information related to the mobile communication terminal from among stored billing information, inserting the found billing information into a ping message, and transmitting the ping message to the mobile communication terminal; and the mobile communication terminal for sending the data call, receiving the assigned IP address, performing wireless data communication using the assigned IP, transmitting a ping response message to the billing server if a ping message is received from the billing server, determining whether the ping message contains billing information, and displaying the billing information contained in the ping message if it is determined that the ping message contains billing information.

Claims

1. A method of providing billing information of a wireless data communication service in a mobile communication terminal, the method comprising the steps of:

sending a data call;

receiving an assigned Internet protocol (IP) address and performing wireless data communication using the assigned IP address;

if a ping message is received from a billing server, transmitting a ping response message to the billing server; and

determining whether the ping message contains billing information and displaying the billing information contained in the ping message if it is determined that the ping message contains billing information.

2. The method of claim 1, further comprising, if a user inputs a specific billing information request, creating a ping message containing a billing code indicating a billing information type corresponding to the specific billing information and transmitting the created ping message to the billing server.

3. The method of claim 2, wherein the step of displaying the billing information contained in the ping message comprises:

comparing data contained in a ping message type field of a data field of the ping message to the assigned IP address; and

if the data contained in the ping message type field matches the assigned IP address, determining that the ping message contains billing information and displaying the billing information contained in the ping message in a text form.

4. A method of providing billing information of a wireless data communication service in a billing server, the method comprising the steps of:

receiving an Internet protocol (IP) address assigned to a certain mobile communication terminal; and

searching for billing information related to the certain mobile communication terminal from among stored billing information, inserting the found billing information into a ping message, and transmitting the ping message to the certain mobile communication terminal.

5. The method of claim 4, further comprising, if a ping response message is not received from the certain mobile communication terminal within a predetermined time, repeatedly transmitting the ping message a predetermined number of times.

6. The method of claim 5, further comprising:

receiving a billing information request ping message from the certain mobile communication terminal;

searching for billing information corresponding to a billing code indicating a billing information type, which is contained in the billing information request ping message;

creating a ping message containing the found billing information and transmitting the created ping message to the certain mobile communication terminal.

7. The method of claim 6, further comprising, when the billing information request ping message is received from the certain mobile communication terminal, comparing an origination address contained in an IP header of the received billing information request ping message to data contained in a ping message type field of a data field of the received billing information request ping message, and if the origination address contained in the IP header matches the data contained in the ping message type field, determining that the received ping message is a billing information request ping message.

8. The method of claim 7, further comprising, if the billing information request ping message is received from the certain mobile communication terminal, transmitting a response ping message to the certain mobile communication terminal.

9. A system for providing billing information of a wireless data communication service, the system comprising:

an Inter-Working function (IWF) for, if a data call is received, assigning an Internet protocol (IP) address to a mobile communication terminal that has sent the data call and transmitting the assigned IP address to a billing server;

the billing server for, if the IP address is received, searching for billing information related to the mobile communication terminal from among stored billing information, inserting the found billing information into a ping message, and transmitting the ping message to the mobile communication terminal; and

the mobile communication terminal for sending the data call, receiving the assigned IP address, performing wireless data communication using the assigned IP address, transmitting a ping response message to the billing server if the ping message is received from the billing server, determining whether the ping message contains billing information, and displaying the billing information contained in the ping message if it is determined that the ping message contains billing information.

10. The system of claim 9, wherein if a user inputs a specific billing information request, the mobile communication terminal creates a ping message containing a billing code indicating a billing information type corresponding to the specific billing information and transmits the created ping message to the billing server.

11. The system of claim 10, wherein when the billing information contained in the ping message is displayed, the mobile communication terminal compares data contained in a ping message type field of a data field of the ping message to the assigned IP address, and if the data contained in the ping message type field matches the assigned IP address, the mobile communication terminal determines that the ping message contains billing information and displays the billing information contained in the ping message in a text form.

12. The system of claim 11, wherein if a ping response message is not received from the mobile communication terminal within a predetermined time, the billing server repeatedly transmits the ping message a predetermined number of times.

13. The system of claim 12, wherein if the billing information request ping message is received from the mobile communication terminal, the billing server searches for billing information corresponding to a billing code indicating a billing information type, which is contained in the billing information request ping message, creates a ping message containing the found billing information, and transmits the created ping message to the mobile communication terminal.

14. The system of claim 13, wherein when the billing information request ping message is received from the mobile communication terminal, the billing server compares an origination address contained in an IP header of the received billing information request ping message to data contained in a ping message type field of a data field of the received billing information request ping message, and determines that the received ping message is a billing information request ping message if the origination address contained in the IP header matches the data contained in the ping message type field.

15. The system of claim 14, wherein if the billing information request ping message is received from the mobile communication terminal, the billing server transmits a response ping message to the mobile communication terminal.
