Abstract:
An information reporting method in a mobile communication system equipped with a first base station and a second base station that communicate with a user device by means of carrier aggregation between base stations, said method being equipped with: a step wherein the first base station transmits to the second base station a configuration change request containing first desired setting information; a second desired information reporting step wherein the second base station reports second desired setting information to the first base station; a step wherein, on the basis of the first desired setting information and the second desired setting information, the first base station determines first setting information and second setting information to be set in the user device, and reports the first setting information and the second setting information to the user device; and a difference reporting step wherein, after the setting of the first setting information and the second setting information in the user device is completed, the difference between the setting information prior to the setting being made and the setting information after the setting has been made is reported to the second base station.
