Abstract

In order to prevent occurrence of the significantly frequent transmission of messages, a user terminal is configured such that, when a reception power of a target cell is equal to or greater than a first threshold value ThLOW, the user terminal starts preparation for a handover to the target cell, and when the reception power is equal to or greater than a second threshold value ThHIGH, the user terminal performs the handover to the target cell, and that, until a waiting time has elapsed after performing the handover, the user terminal, by using a timer, performs a timing control for maintaining an immediate handover state in which the user terminal can immediately perform a handover, and, when the waiting time has elapsed, the user terminal ends the immediate handover state.
