Abstract: A method and apparatus for establishing a session in a wireless communication system is provided. An entity of a primary radio access technology (RAT) system receives measurement results on the primary RAT system and a secondary RAT system from a multi-RAT device, determines a routing rule and a routing type for bearers which are appropriate for simultaneous transmission through the primary RAT system and the secondary RAT system, based on quality of service (QoS) and the measurement results, and transmits a routing control request message to a packet data network (PDN) gateway (P-GW). The routing control request message includes identifiers (IDs) of the bearers which are appropriate for simultaneous transmission, the routing type for each bearer, and the routing rule for each bearer.

Abstract: The present invention relates to a method for managing information of on/off small cells in a small cell-based network system and apparatuses for supporting the same. As an embodiment of the present invention, a method for managing information on on/off small cells in a radio access system supporting small cells comprises the steps of: receiving a first message including cell state change information of a first cell corresponding to a small cell, which is changed to an on state or an off state, by a second cell; and transmitting a second message including the cell state change information to a UE by the second cell. At this time, the cell state change information may contain identification information of the first cell, on/off time information indicating a time when change to an on state or an off state is made, and on/off timer information indicating a time interval in which the change to the on state or the off state is made.
