Method for transmitting and receiving data using WLAN carriers and apparatus thereof

Abstract:

The present embodiment relates to a method and an apparatus for controlling a base station and a terminal to transmit ad/or receive specific user plane data through a WLAN carrier while transmitting the user plane data by adding the WLAN carrier to the E-UTRAN carrier in the RAN (Wireless Access Network) level. In particular, a method may be provided for transmitting and receiving data by a terminal. The method may include: receiving configuration information for transmitting and receiving data to and from a base station by using an IPsec (Internet Protocol Security) tunnel through a WLAN (wireless local area network) carrier, configuring the IPsec tunnel based on the configuration information and setting a data bearer by using the IPsec tunnel; and transmitting, to the base station, data that is received by using the IPsec tunnel from the upper layer in a tunnel entity of the terminal.
