Abstract: The present invention relates to a method for offloading traffic by means of wireless LAN in a mobile communications system and apparatus therefor, and more particularly to a method for a terminal to offload traffic at a bearer level, and to a base station communicating with the terminal. The method for a terminal to offload traffic according to the present invention includes the steps of: while performing a data communication with a base station through a bearer of a first communications network, receiving from the base station an offloading command for offloading a part of traffic to a second communications network; transmitting a report of the offloading to the base station in response to the offloading command; and performing a data communication of the partial traffic with an accessible AP through a bearer of the second communications network without releasing the bearer of the first communications network.

Abstract: The present disclosure relates to a communication system and technique that may be applied to intelligent services based on a 5G communication technology and an IoT-related technology. The present disclosure provides a method for data transmission of a terminal in a wireless communication system that includes inputting a packet data convergence protocol packet data unit (PDCP PDU) output from a PDCP entity to a first radio link control (RLC) entity and a second RLC entity. The method also includes inputting a first radio link control packet data unit (RLC PDU) output from the first RLC entity and a second RLC PDU output from the second RLC entity to a medium access control (MAC) entity and transmitting a medium access control packet data unit (MAC PDU) output from the MAC entity through a first physical layer (PHY) entity and a second physical layer entity.
