Abstract: Disclosed is a method for controlling a security mode by a user equipment (UE) in a wireless communication system, including performing a camp-on process and a cell update process with a network when an out-of-service (OOS) situation has occurred, receiving one of a signaling connection release (SCR) message and a first protocol data unit (PDU) which corresponds to the SCR message from the network, receiving a security mode command (SMC) message from the network if the SCR message is received, performing an integrity process on the SCR message using an old security configuration, and performing a rollback process to discard a new security configuration included in the SMC message if a result of the integrity process result an integrity check success, and updating a security configuration to the old security configuration.

Abstract: A method for operating of a terminal in a communication system is provided. The method includes receiving first information for cell reselection, reconfiguring an expiration time of a cycle of a timer of the terminal based on the received first information for cell reselection, and determining second information for cell reselection at the reconfigured expiration time of the cycle of the timer of the terminal for cell reselection.

Abstract: An apparatus and a method for switching a Radio Access Technology (RAT) by a User Equipment (UE) in a wireless communication system are provided. The method includes detecting an event indicating that the UE should perform a switching operation from a first RAT to a second RAT different from the first RAT occurs while the UE uses the first RAT determining whether a RAT switching operation criterion is satisfied after detecting that the event occurs and if the RAT switching operation criterion is satisfied, performing the switching operation.
