Abstract

Disclosed is a mobile communication terminal and method for receiving a positioning information service, and an Internet protocol network system and method for providing the same. The Internet protocol network system for providing mobility service includes a router for periodically broadcasting an advertisement message which includes positioning information and a mobile communication terminal for receiving the advertisement message, reading the positioning information, and determining a position of the mobile communication terminal based on the read positioning information. The method for providing mobility service in an Internet protocol network includes periodically broadcasting an advertisement message by a router, receiving the advertisement message by a mobile communication terminal and reading positioning information from the received advertisement message and recognizing a position of the mobile communication terminal based on the read positioning information, by the mobile communication terminal.

Claims

1. An Internet protocol network system for providing mobility service, the Internet protocol network system comprising:

a router for periodically broadcasting an advertisement message which includes positioning information; and

a mobile communication terminal for receiving the advertisement message, reading the positioning information, and determining a position of the mobile communication terminal based on the read positioning information.

2. The Internet protocol network system as claimed in claim 1, wherein the advertisement message includes an option field, and the router inserts a positioning option into the option field and broadcasts the advertisement message.

3. The Internet protocol network system as claimed in claim 2, wherein when the mobile communication terminal receives another advertisement message, the mobile communication terminal:

determines whether a positioning option is included in the another advertisement message; and

reads positioning information, when it is determined that the positioning option is included in the another advertisement message.

4. A method for providing mobility service in an Internet protocol network, the method comprising the steps of:

periodically broadcasting an advertisement message, by a router;

receiving the advertisement message, by a mobile communication terminal; and

reading positioning information from the received advertisement message and recognizing a position of the mobile communication terminal based on the read positioning information, by the mobile communication terminal.

5. The method as claimed in claim 4, further comprising:

determining whether a positioning option is included in the received advertisement message, by the mobile communication terminal; and

reading the positioning information when it is determined that the positioning option is included in the received advertisement message, by the mobile communication terminal.

6. The method as claimed in claim 4, further comprising:

determining a change of current router to another router, to which the mobile communication terminal is connected; and

updating position information of the mobile communication terminal using positioning information provided by the another router.

7. The method as claimed in claim 6, further comprising registering the mobile communication terminal with the another router.

8. A mobile communication terminal comprising:

a reception unit for periodically receiving an advertisement message from a router of an Internet protocol network; and

a control unit for;

reading positioning information from a received advertisement message when the advertisement message is received; and

determining a position of the mobile communication terminal based on the read positioning information.

9. The mobile communication terminal as claimed in claim 8, wherein, the control unit determines whether a positioning option is included in the received advertisement message, and reads positioning information when it is determined that the positioning option is included in the received advertisement message.

10. A method for receiving a positioning information service by a mobile communication terminal in an Internet protocol network, the method comprising the steps of:

determining whether another advertisement message is received from a router;

reading positioning information from the received advertisement message if it is determined that the another advertisement message is received from the router, and

determining a position of the mobile communication terminal based on the read positioning information.

11. The method as claimed in claim 10, further comprising:

determining, by the mobile communication terminal, whether a positioning option is included in the another advertisement message; and

reading, by the mobile communication terminal, the positioning information, if it is determined that the positioning information is included in the another advertisement message.

12. The method as claimed in claim 10, further comprising

determining a change of current router to another router to which the mobile communication terminal is connected;

and

updating position information of the mobile communication terminal using positioning information provided by the another router.

13. The method as claimed in claim 12, further comprising registering the mobile station terminal with the another router.
