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 of a terminal to an idle mode by a base station in a wideband wireless communication system, the method comprising:

transmitting an unsolicited deregistration response message to the terminal, the unsolicited deregistration response message including a MAC control extended header (MCEH) in which a poll bit for reporting whether or not a message has been received is set, an action code for instructing the terminal to transmit a deregistration request message for a transition to an idle mode, and the deregistration request message transmission time information;

receiving the 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 poll bit is included in a MAC control message ACK extended header (MAEH) of the received deregistration request message;

transmitting, to the terminal, a first deregistration response message including a first action code which permits the terminal to transit into the idle mode according to an unsolicited deregistration mode, when the response information is included in the MAEH of the received deregistration request message; and

transmitting, to the terminal, a second deregistration response message including a second action code which permits the terminal to transit into the idle mode according to a solicited deregistration mode, when the response information is not included in the MAEH of the received deregistration request message.

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

3. A base station for controlling a transition of a terminal to an idle mode in a wideband wireless communication system, the base station configured to:

transmit an unsolicited deregistration response message to the terminal, the unsolicited deregistration response message including a MAC control extended header (MCEH) in which a poll bit for reporting whether or not a message has been received is set, an action code for instructing the terminal to transmit a deregistration request message for a transition to an idle mode, and the deregistration request message transmission time information;

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

determine whether or not response information with respect to the poll bit is included in a MAC control message ACK extended header (MAEH) of the received deregistration request message;

transmit, to the terminal, a first deregistration response message including a first action code which permits the terminal to transit into the idle mode according to an unsolicited deregistration mode, when the response information is included in the MAEH of the received deregistration request message; and

transmit, to the terminal, a second deregistration response message including a second action code which permits the terminal to transit into the idle mode according to a solicited deregistration mode, when the response information is not included in the MAEH of the received deregistration request message.

4. The base station of claim 3, wherein the transmission time information is REQ-Duration.
