Abstract: A method of supporting signal transmission/reception using at least two RATs and apparatus therefor are disclosed. The present invention includes, when a user equipment is simultaneously accessing a 1st base station of a 1st communication network supportive of a 1st RAT and a 2nd base station of a 2nd communication network supportive of a 2nd RAT, receiving a setup message indicating a termination of a connection to the 2nd base station from the 1st base station and terminating the connection to the 2nd base station. Before the connection to the 2nd base station is terminated, the user equipment transceives data for a specific traffic type via the 2nd base station and also transceives data except the specific traffic type via the 1st base station. If the connection to the 2nd base station is terminated, the user equipment transceives the data for the specific traffic type via the 1st base station.
