    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.

    Abstract: Disclosed is a 5th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than that of a 4th generation (4G) communication system such as long term evolution (LTE). According to various embodiments of the disclosure, provided is a method for operating an access and mobility management function (AMF) in a wireless communication system, comprising the steps of: receiving, from user equipment (UE), a service request including a list of protocol data unit (PDU) sessions to be activated, or a message about a mobility registration update; checking, on the basis of UE context information about the UE, whether identifiers (IDs) of all of always-on PDU sessions are included in the list of PDU sessions to be activated; and, when an omitted always-on PDU session is checked from the list of the PDU sessions to be activated, transmitting, to a session management function (SMF), a Nsmf_PDUSession_UpdateSMContext request message for requesting user plane activation of the omitted always-on PDU session.
