Abstract: The present invention provides methods and apparatus for controlling and resolving a handover failure when a dynamic cell off is occurred during a handover procedure. According to one aspect of the present invention, a method for preventing a handover failure in a wireless access system supporting cell-on/off includes initiating a handover procedure to a target Base Station (BS) by a User Equipment (UE), receiving cell off indication information indicating that a cell of the target BS will be powered off by the UE, and discontinuing the handover procedure according to the cell off indication information by the UE.

Abstract: 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.
