    Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). A method for processing a radio link failure (RLF) by a user equipment (UE) supporting a dual-connectivity communication system is provided. The method includes determining a state of a radio link with a first base station using a reference signal, transmitting to a second base station, when the radio link with the first base station fails, a message indicating that the radio link with the first base station fails, redetermining the state of the radio link with the first base station using a reference signal of the first base station during a predetermined time, and switching, after the predetermined time, a data transmission line when the radio link with the first base station fails.
