Abstract

Disclosed is a method of controlling a transition to an idle mode in an operation method for transitioning to an idle mode in a wideband wireless communication system, including: receiving an unsolicited deregistration response message including an action code instructing the terminal to transmit a deregistration request message for a transition to an idle mode and deregistration request message transmission time information from a base station; extracting control information in which a poll bit for reporting whether or not a message has been received is set from the received unsolicited deregistration response message; transmitting a deregistration request message including response information with respect to the extracted control information and a deregistration request code for requesting a transition to an idle mode, to the base station; and receiving a deregistration response message including an action code permitting a transition to an idle mode,

Claims

1. A method of controlling a transition to an idle mode in an operation method for transitioning to an idle mode in a wideband wireless communication system, the method comprising:

receiving an unsolicited deregistration response message including an action code instructing the terminal to transmit a deregistration request message for a transition to an idle mode and deregistration request message transmission time information from a base station;

extracting control information in which a poll bit for reporting whether or not a message has been received is set from the received unsolicited deregistration response message;

transmitting a deregistration request message including response information with respect to the extracted control information and a deregistration request code for requesting a transition to an idle mode, to the base station; and

receiving a deregistration response message including an action code permitting a transition to an idle mode, from the base station.

2. The method of claim 1, wherein the control information is a MAC control extended header.

3. The method of claim 1, wherein the response information is a MAC control message ACK extended header.

4. The method of claim 1, wherein the transmission time information is REQ-Duration.

5. A method of controlling a transition to an idle mode in an operation method of a base station for controlling a transition of a terminal to an idle mode in a wideband wireless communication system, the method comprising:

transmitting an unsolicited deregistration response message to the terminal;

receiving a deregistration request message including a deregistration request code for requesting a transition to an idle mode from the terminal; and

determining whether or not response information with respect to the control information is included in the received deregistration request message,

wherein the unsolicited deregistration response message includes at least one of control information in which a poll bit for reporting whether or not a message has been received, an action code instructing the terminal to transmit a deregistration request message for a transition to an idle mode, and the deregistration request message transmission time information.

6. The method of claim 5, wherein the control information is a MAC control extended header, the response information is a MAC control message ACK extended header, and the transmission time information is REQ-Duration.

7. The method of claim 5, further comprising:

transmitting a deregistration response message including an action code permitting a transition to an idle mode to the terminal.

8. The method of claim 5, further comprising:

re-transmitting the unsolicited deregistration response message, which has been transmitted to the terminal, when the response information is not included in the received deregistration request message.

9. The method of claim 8, wherein, in the re-transmitting of the unsolicited deregistration response message, the unsolicited deregistration response message is repeatedly transmitted until such time as a re-transmission count reaches a maximum count.

10. The method of claim 9, further comprising:

after the unsolicited deregistration response message is repeatedly transmitted up to the maximum count, when there is no response information received from the terminal with respect to the control information, deleting the terminal from a management list of the base station.

11. A method of controlling a transition to an idle mode in an operation method for transitioning to an idle mode in a wideband wireless communication system, the method comprising:

receiving an unsolicited deregistration response message including an action code instructing the terminal to transmit a deregistration request message for a transition to an idle mode and deregistration request message transmission time information from a base station;

extracting control information in which a poll bit for reporting whether or not a message has been received is set from the received unsolicited deregistration response message;

transmitting a response message with respect to the extracted control information to the base station;

transmitting a deregistration request message including a deregistration request code for requesting a transition to an idle mode, to the base station; and

receiving a deregistration response message including an action code permitting a transition to an idle mode, from the base station.

12. The method of claim 11, wherein the control information is a MAC control extended header, the response message is an MSG-ACK message, and the transmission time information is REQ-Duration.
