Apparatus and method for transmitting or receiving signal in mobile communication network

A base station in a mobile communication network, comprising:

• a transceiver;
• and
• a controller connected to the transceiver, and configured to:
• detect a traffic characteristic for traffic provided to a terminal,
• determine a first radio access technology (RAT) to be applied to an uplink for the terminal and a second RAT to be applied to a downlink for the terminal based on the traffic characteristic and based on at least one of a mobile communication service provider policy and subscriber information of the terminal,
• control a communication with the terminal based on the first RAT and the second RAT,
• calculate a ratio of downlink traffic to uplink traffic,
• compare the calculated ratio with a threshold,
• in response to the calculated ratio exceeding the threshold, control transmitting downlink traffic through a wireless local access network (LAN) scheme and receiving uplink traffic through a long term evolution (LTE) scheme, and
• in response to the calculated ratio not exceeding the threshold, control transmitting the downlink traffic and receiving the uplink traffic through the wireless LAN scheme,
• wherein the traffic characteristic comprises the ratio of downlink traffic to uplink traffic.
