Abstract:
Disclosed herein relates to a sleep mode operation method, and the method of updating a sleep mode operation according to the present invention may include receiving a service flow configuration request (DSx-REQ) message comprising a service flow parameter for service flow configuration and a sleep cycle ID (SCID) for sleep mode change according to the service flow configuration from a base station during a sleep mode listening window; transmitting a service flow configuration response (DSx-RSP) message comprising the SCID; and configuring the service flow according to the service flow identifier, and changing a SCID to the SCID to update the sleep mode operation.
Abstract:
The present invention relates to a wireless access system to which a femto cell is applied. In addition, the present invention relates to an initial access method in a femto cell environment, a method for handover to a femto cell and apparatus for supporting the methods.
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.
Abstract:
Disclosed is a method for transmitting channel quality indicator (CQI) during a sleep mode operation. The method for transmitting CQI includes: receiving a message including a CQI-related parameter indicating a transmission of a CQI before a listening window; transmitting a CQI during a sleep window before the listening window according to a CQI-related parameter in the message; transitioning to the listening window according to a listening window-related parameter after transmitting the CQI; and waiting for receiving a message indicating whether or not there is data or traffic transferred from the base station during the listening window.
Abstract:
Disclosed is a method of allowing a terminal to provide an emergency service in a broadband wireless communication system, and the method may include receiving a first map message including an emergency service indicator; checking whether information indicating that emergency service information is transmitted is included in the received first map message; and receiving a first message including the emergency service information when the information indicating that emergency service information is transmitted is included therein as a result of the check, wherein the emergency service indicator is information indicating at least one of whether to transmit emergency service information and a transmission timing of the emergency service information.
Abstract:
Disclosed is a method of driving a terminal for receiving a broadcast control message formed of a MAC PDU from a wireless access system. The method includes receiving at least one broadcast control message from a base station in a resource region where a broadcast control message is transmitted, extracting broadcast control message type information that represents the kind of a broadcast control message included in the header of the received broadcast control message, and checking the extracted broadcast control message type information and determining whether payload of the received broadcast message is decoded.

Abstract:
Disclosed herein relates to a method and apparatus of sleep mode operation in a multi-carrier system. In a communication system of transmitting and receiving data using a multi-carrier including a primary carrier for transmitting and receiving control information and data and a secondary carrier using a radio frequency (RF) different from the primary carrier, a method of establishing a sleep mode operation through active primary and secondary carriers according to an embodiment of the present invention may include transmitting a sleep cycle ID (SCID), a listening window, and traffic indication inactive information indicating that an indication (TRF-IND) as to whether traffic is generated is not transferred to a terminal through the primary carrier, sending downlink data to the terminal through the active primary or secondary carrier during the listening window, and sending a listening window early termination indication indicating to early terminate the listening window of the primary or secondary carrier that has received the downlink data through the primary carrier to the terminal if the data sending is completed.
Abstract:
Disclosed herein relates to a sleep mode operation method, and more particularly, to a method for operating a sleep mode in a mobile communication terminal, including transmitting a sleep mode request message including a sleep cycle information for entering into the sleep mode to a base station; receiving a sleep mode response message including a sleep mode operating parameter from the base station; changing the state to the sleep mode referring to the sleep mode operating parameter; receiving a traffic indication message including a positive traffic indicator from the base station; and adjusting to a current sleep cycle according to the sleep cycle information included in the sleep mode request message; wherein the sleep cycle information is an information indicating to extend a current sleep cycle to the small value of twice the previous sleep cycle and a final sleep cycle or to reset the current sleep cycle to an initial sleep cycle or a new initialized sleep cycle.
