Abstract: A method for and apparatus for performing handover in a wireless communication system is provided. A wireless device transmits measurement results configured for a secondary radio access technologies (RAT) system, receives information on routing modification based on the measurement results, from a network entity of a primary RAT system and performs a handover to a target access network according to the information on routing modification. The secondary RAT system is used for a user plane (U-plane) data, and the handover is determined based on at least one of a quality of service (QoS) information, load information about the primary RAT system and secondary RAT system, and a network preference information of the UE.

Abstract: Provided is a method for receiving system information by a terminal in a cloud wireless communication system including one or more baseband units (BBUs) and remote radio units (RRUs), the one or more RRUs being connected to a particular BBU among the BBUs to provide a direct service to the terminal via one or more cells. The method is characterized in that the terminal receives, from the network, an identifier that can understand whether there are any changes in the BBU, the RRU, and the cell, and through the received identifier understands whether there are one or more changes among the BBU, the RRU, and the cell, and selectively receives, from the network, the only system information required for any one among the BBU change, the RRU change, and the cell change.

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.
