Abstract:
A method for operating an overlay macro base station (BS) for discovering a closed subscriber group (CSG) user equipment (UE) in a femto cell, includes: receiving a ranging request message including a CSG ID information from a UE which attempts a network entry; and after receiving the ranging request message from the UE, recommending the femto cell to monitor uplink signaling of a CSG UE belonging to the overlay macro BS.
Abstract:
This document is related to a method for acquiring information for media independent handover. More specifically the method comprises: submitting a media independent handover (MIH) query to a base station (BS) by sending a first request message, and receiving a response to the MIH query. Because the first request message is used for authorization, preferably the PKM message, the MS can acquire information for handover between heterogeneous networks before the MS finishes the network entry.
Abstract:
The present invention relates to a broadband wireless access system, and more particularly, to a method for a mobile station to save power for prescribed duration without performing a paging procedure and apparatus therefor. According to one embodiment of the present invention, a method of a DCR (deregistration with content retention) mode operation of a mobile station in a broadband wireless access system includes transmitting a first message including a first code indicating an entry request at the DCR mode to a base station, receiving a second message including a second code indicating whether to allow the entry request from the base station, and if the second code is set to a value indicating an allowance of the entry request, operating in the DCR mode while a preset timer is valid.
Abstract:
A method for updating a neighbor list at a femto Base Station (BS) is disclosed. The method includes broadcasting a first broadcast message including information about an unavailable time interval during which scheduling is not performed for Mobile Stations (MSs), scanning at least one neighbor BS during the unavailable time interval, and updating the neighbor list according to a result of the scanning.
Abstract:
A method of communicating information in a wireless mobile communication system is disclosed. More specifically, the method includes a network for establishing handover management modules in a source network and a target network and transmitting a handover request message from the handover management module of the source network to the handover management module of the target network. Furthermore, the network is used for receiving a handover response message from the handover management module of the target network to the handover management module of the source network, wherein the handover response message includes an internet protocol address information and transmitting a handover confirmation message from the handover management module of the source network to a mobile terminal, wherein the handover confirmation message includes the internet protocol address information.
