| 20140211763 | METHOD AND APPARATUS FOR CONTROLLING AND SUPPORTING A DYNAMIC CELL ON/OFF IN WIRELESS ACCESS SYSTEM - The present invention relates to a wireless access system and provides methods and apparatuses for controlling and supporting dynamic cell on or off. In an embodiment of the present invention, a method for supporting on or off of a second cell at a first cell in a wireless access system includes receiving a cell on/off state indicator message indicating on or off of the second cell from the second cell, adjusting a handover offset of the second cell, taking into account interference caused by the on or off of the second cell, and transmitting handover offset information about the adjusted handover offset to at least one of the second cell and a first User Equipment (UE). | 07-31-2014 |
| 20140213239 | METHOD AND APPARATUS FOR CONTROLLING A SMALL CELL ON OR OFF PROCEDURE - The present application provides methods for controlling a small cell on or off procedure in a Small cell specific Gate Way (S-GW). One of the methods comprises steps of receiving a cell indication message from a Source Small Cell (SSC), the cell indication message includes a cell state change indication parameter indicating whether the SSC is to be on or off and a cell on/off timer parameter indicating a time duration for a cell on process or a cell off process; transmitting request message requesting to expand or shrink a cell coverage of a Target Small Cell (TSC) according to the cell state change indication parameter; and receiving a complete indication message indicating the cell on process or the cell off process is complete after the time duration indicated by the cell on/off timer parameter from the SSC. | 07-31-2014 |
| 20140235218 | METHOD AND APPARATUS FOR CONTROLLING A SMALL CELL ON OR OFF PROCEDURE FOR COVERAGE EXTENSION - The present invention relates to methods and apparatuses for supporting or controlling a small cell on or off procedure. The method may comprise steps of receiving, by the MSC from a Source Small Cell (SSC), a Cell Off Indication message including a Cell State Change Indication parameter indicating a cell status of the SSC; transmitting, by the MSC to the SSC, an Expand Indication message indicating an expanding of the MSC when the Cell State Change Indication parameter indicates a cell off status, the Expanding Indication message including a Time to Start Expand parameter indicating when the MSC starts an expanding of its coverage and an Expand Timer parameter indicating a time period during which the expanding is performed; and starting the expanding of its coverage at a time indicated by the Time to Start Expand parameter during the time period indicated by the Expand Timer. | 08-21-2014 |
| 20140301308 | METHOD AND APPARATUS FOR PERFORMING PLURAL NETWORK ATTACHMENT PROCEDURES TO SUPPORT PLURAL CONNECTIONS IN A WIRELESS ACCESS SYSTEM - A method and apparatus for performing a plurality of network attachment procedures to support a plurality of cells for a small cell-based User Equipment (UE) service are disclosed. | 10-09-2014 |
| 20140334465 | METHOD AND APPARATUS FOR PAGING BASED ON LOCATION INFORMATION OF A USER EQUIPMENT IN A CONVERGENCE NETWORK OF A PLURALITY OF COMMUNICATION SYSTEMS - A method and apparatus for paging based on location information of a user equipment connected to a first communication system in a convergence network of a plurality of communication systems. A method for paging based on location information of a user equipment connected to a first communication system in a convergence network of a plurality of communication systems includes receiving, from a interworking entity of the second communication system, the location information of the user equipment which is in an idle mode with the second communication system; transmitting, to a first cell of the second communication system, a paging request message, wherein the first cell is selected from among a plurality of cells in a tracking area of the second communication system based on the location information. | 11-13-2014 |
| 20140335859 | METHOD AND UE FOR NETWORK ATTACHMENT - A method and a user equipment (UE) for network attachment are disclosed. The method includes receiving first status information associated with one or more remote radio units (RRUs) for supporting the small cell from the one or more RRUs, receiving second status information associated with one or more macro cells from one or more macro eNBs for supporting the macro cell, selecting an RRU and macro eNB, which the UE wants to attach, among the one or RRUs based on the first status information and the second status information, and simultaneously transmitting an attach request message for requesting network attachment from the selected RRU and macro eNB to the selected RRU and macro eNB. | 11-13-2014 |
| 20140349667 | METHOD OF PERFORMING COMMUNICATION BY USER EQUIPMENT IN CLOUD RADIO ACCESS NETWORK ENVIRONMENT AND APPARATUS THEREFOR - The present invention relates to a method of configuring a user equipment-based communication area in a cloud radio access network environment and an apparatus therefor. As one embodiment of the present invention, a method of performing a communication, which is performed by a user equipment (UE) in a cloud radio access network environment includes the steps of generating an RRU list based on signal strength of downlink signals received from each of one or more RRUs (remote resource unit), setting a UE-based communication area in a manner of transmitting the RRU list to a BBU (base band unit) via a first RRU among the one or more RRUs and establishing an RRC connection with a second RRU within the UE-based communication area. | 11-27-2014 |
| 20150296496 | METHOD AND APPARATUS FOR REGISTERING ACCESS POINT THROUGH WIFI NETWORK BY USING INFORMATION OBTAINED FROM COMMON DEVICE IN CELLULAR-WIFI CONVERGENCE SYSTEM - The present invention relates to a method and apparatus for registering an access point through a WiFi network using information obtained from a common device in a cellular-WiFi convergence system. The present invention provides a method in which a sub-RAT system entity obtains main RAT system information through a common device and a WiFi network thereof in a communication system in which a cellular system and a WiFi system are converged, and notifies a managing device of information thereon through the WiFi network. | 10-15-2015 |
