    Abstract: The present disclosure relates to a method and apparatus for optimizing mobility robustness by controlling an inter-Radio Access Technology (inter-RAT) factor. A method for supporting inter-Radio Access Network (RAN) mobility by a source Base Station (BS) in a wireless communication system includes transmitting a handover request message to a target BS, receiving a RAN information request message including a measurement report from the target BS in response to the handover request message, and determining to amend a mobility setting, if it is determined that an unnecessary handover has occurred based on the RAN information request message. The handover request message includes at least one of a Tracking Area Identifier (TAI) of a tracking area to which the source BS belongs, a global BS Identifier (ID), and an E-UTRAN (Evolved-UMTS (Universal Mobile Telecommunication System) Terrestrial Radio Access Network) Cell Global ID (ECGI).

    Abstract: The present invention relates to a method and an apparatus for transmitting data to user equipment through not only a current base station cell but also a neighboring base station cell via inter-eNB CA in a wireless communication system. A method for transmitting data though carrier aggregation in the wireless communication system, according to the present invention, comprises the steps of: a first base station transreceiving data with a terminal through at least two PDN connections; the first base station transmitting a carrier aggregation request message to a second base station for aggregating carriers, when the first base station determines to carry out inter-eNB carrier aggregation; the first base station receiving a carrier aggregation reply message from the second base station in response to the carrier aggregation request message; the first base station performing an RRC reconfiguration process with the terminal to notify to the terminal of the determination to perform the inter-eNB carrier aggregation; and the first base station transmitting a path change request message to a mobile management entity to correct a data transreceiving path, so that data on at least one PDN connection from among the PDN connections is transreceived through the second base station.
