Abstract
Methods and apparatuses are provided for controlling a user equipment (UE) in a mobile communication system is provided. A first security mode command message for security authentication of the UE is received from a first base station (BS). It is determined whether a cell reselection event between the UE and a second BS is generated before the security authentication with the first BS is completed. The UE is controlled so that security states of the UE and the second BS match, when the cell reselection event is generated before the security authentication with the first BS is completed.
