Abstract

A mobile internet system, mobile communication terminal thereof and method of controlling operation thereof are disclosed. According to an embodiment, the mobile internet system includes a mobile communication terminal configured to execute at least one of a scanning procedure and a ranging procedure. The mobile communication terminal first executes the scanning procedure rather than the ranging procedure in an interval where the scanning procedure and the ranging procedure are overlapped with each other.

Claims

1. A mobile internet system comprising:

a mobile communication terminal configured to execute at least one of a scanning procedure and a ranging procedure,

wherein the mobile communication terminal first executes the scanning procedure rather than the ranging procedure in an interval where the scanning procedure and the ranging procedure are overlapped with each other.

2. The mobile internet system of claim 1, further comprising:

a base station configured to transmit a message instructing to execute the scanning procedure preferentially in the interval where the scanning procedure and the ranging procedure are overlapped with each other,

wherein the mobile communication terminal executes the scanning procedure over the ranging procedure, if the message is received from the base station.

3. The mobile internet system of claim 2, wherein the message is a response message responsive to a scanning request message transmitted from the mobile communication terminal to the base station.

4. A mobile internet system comprising:

a base station configured to select a procedure to be preferentially executed in an interval where a scanning procedure and a ranging procedure are overlapped with each other, and to transmit the procedure selection; and

a mobile communication terminal configured to receive the procedure selection from the base station, and to execute either the scanning procedure or the ranging procedure in the interval where the scanning procedure and the ranging procedure are overlapped with each other according to the received procedure selection.

5. The mobile internet system of claim 4, wherein the base station selects the procedure to be preferentially executed according to channel status information received from the mobile communication terminal.

6. The mobile internet system of claim 5, wherein the mobile communication terminal transmits the channel status information to the base station using a scanning result report message.

7. The mobile internet system of claim 4, wherein the base station transmits the procedure selection to the mobile communication terminal using a response message responsive to a scanning request message transmitted from the mobile communication terminal to the base station.

8. A mobile internet system comprising:

a mobile communication terminal configured to select, based on status information, a procedure to be preferentially executed in an interval where a scanning procedure and a ranging procedure are overlapped with each other, and to execute either the scanning procedure or the ranging procedure according to the procedure selection.

9. The mobile internet system of claim 8, wherein the status information is previously obtained channel status information, and the mobile communication terminal compares a channel status obtained from the channel status information with reference information to make the procedure selection.

10. A mobile communication terminal for a mobile internet system, the mobile communication terminal comprising:

a transceiver configured to receive, from a base station, a message instructing a procedure to be preferentially executed in an interval where a scanning procedure and a ranging procedure are overlapped; and

a control unit configured to execute either the scanning procedure or the ranging procedure in the interval where the scanning procedure and the ranging procedure are overlapped with each other according to the message received by the transceiver.

11. The mobile communication terminal of claim 10, wherein the received message is a response message responsive to a scanning request message transmitted to the base station by the transceiver.

12. A mobile communication terminal for a mobile internet system, the mobile communication terminal comprising:

a storage unit configured to store channel status information for each base station; and

a control unit configured to select a procedure to be preferentially executed among a scanning procedure and a ranging procedure based on the stored channel status information, if the control unit determines that the scanning procedure and the ranging procedure are overlapped with each other in a prescribed interval.

13. A mobile communication terminal for a mobile internet system, the mobile communication terminal comprising:

a controller configured to automatically execute a scanning procedure preferentially rather than a ranging procedure in an interval where the scanning procedure and the ranging procedure are overlapped with each other.

14. A method of controlling an operation in a mobile internet system including a mobile communication terminal configured to execute at least one of a scanning procedure and a ranging procedure, the method comprising:

if there exists an interval where the scanning procedure and the ranging procedure are overlapped with each other, executing, by the mobile communication terminal, the scanning procedure preferentially rather than the ranging procedure in the interval.

15. The method of claim 14, further comprising:

receiving, by the mobile communication terminal from a base station, a message instructing to execute the scanning procedure preferentially in the interval, wherein the executing step is performed in response to the received message.

16. The method of claim 15, wherein the received message is a response message responsive to a scanning request message transmitted from the mobile communication terminal to the base station.

17. A method of controlling an operation in a mobile internet system including a base station and a mobile communication terminal configured to execute at least one of a scanning procedure and a ranging procedure, the method comprising:

selecting, by the base station, a procedure to be preferentially executed in an interval where the scanning procedure and the ranging procedure are overlapped with each other;

transmitting the selection result, by the base station, to the mobile communication terminal;

determining, by the mobile communication terminal, whether there exists the interval where the scanning procedure and the ranging procedure are overlapped with each other; and

executing, by the mobile communication terminal, either the scanning procedure or the ranging procedure according to the received selection result.

18. The method of claim 17, wherein in the selecting step, the procedure to be preferentially executed is selected using channel status information received from the mobile communication terminal.

19. The method of claim 18, wherein the channel status information is transmitted from the mobile communication terminal to the base station using a scanning result report message.

20. The method of claim 17, wherein in the transmitting step, the selection result is transmitted from the base station to the mobile communication terminal using a response message responsive to a scanning request message sent from the mobile communication terminal to the base station.

21. A method of controlling an operation in a mobile internet system including a mobile communication terminal configured to execute at least one of a scanning procedure and a ranging procedure, the method comprising:

selecting, by the mobile communication terminal, a procedure to be preferentially executed in an interval where the scanning procedure and the ranging procedure are overlapped with each other, based on status information; and

executing either the scanning procedure or the ranging procedure according to the selection result.

22. The method of claim 21, wherein the status information is channel status information pre-stored in the mobile communication terminal.

23. The method of claim 21, wherein the selecting step includes:

comparing a channel status obtained from the status information with reference information, and

selecting either the scanning procedure or the ranging procedure according to the comparison result, as the procedure to be preferentially executed in the interval.

24. The method of claim 23, wherein the ranging procedure is selected as the procedure to be preferentially executed in the interval, if the channel status satisfies the reference information.

25. The method of claim 23, wherein the scanning procedure is selected as the procedure to be preferentially executed in the interval, if the channel status does not satisfy the reference information.
