Abstract:
Provided are a method and device for ranging in a wireless communication system. A machine-to-machine (M2M) device receives an advanced air interface-system configuration descriptor (AAI-SCD) message including information on a dedicated ranging channel for the M2M device and an M2M parameter change count from a base station, and attempts ranging through the dedicated ranging channel to the base station. At this point, the M2M parameter change count orders information on the dedicated ranging channel in the AAI-SCD message to change.
Abstract:
A method for transmitting information of a network interworking with a wireless LAN (802.11, Wi-Fi) network or EMID (ESS MAC ID) provided from an EMID server to a wireless user equipment if the wireless user equipment accesses the wireless LAN network is disclosed. A wireless communication system which performs communication using a plurality of subcarriers includes at least one access point receiving messages from at least one wireless user equipment and communicating with another access point through a distribution system, and at least one interworking information broker receiving information request message of subscriber service provider network (SSPN) through interface with the at least one access point and acquiring response information corresponding to the information request message through interface with a network entity which includes information of the SSPN, the information request message of the SSPN being transmitted from the wireless user equipment to the at least one access point.

Abstract:
A method and apparatus for reducing interference between systems when a plurality of wireless access systems are co-located are disclosed. To support CLC mode, an MS in the CRC mode transmits a handover request message to a first Base Station (BS) to initiate a handover process, receives a handover command message acknowledging the handover request message from the first BS, transmits a ranging request message to second BS at network reentry after handover, and receives from the second BS a ranging response message including CRC start time information that set by the second BS.
Abstract:
The primitives between an upper management layer and the MAC layer within a mobile station and a base station are defined in order to specify and clarify the operations within the protocol stack layers in a broadband wireless access system to allow management of a mobile station. Media Independent Handover (MIH) procedures can be achieved because the NCMS and MIH layer can communicate through use of these primitives.

Abstract:
Disclosed is a communication technique using the change of type of a femto base station. The femto base station is able to change the type of CSG opening/closing depending on conditions, and broadcasts the information on the change. A terminal is able to determine the network entry/handover to a corresponding femto cell by using the broadcasted information. The change of cell type of a CSG femto cell can be used when interference adjustment is required depending on the resource conditions of a femto cell.
