Abstract  Abstract

providing a random access process control method and device for efficiently controlling the random access procedure in a mobile communication system supporting carrier aggregation. for the random access process has main cell and at least one auxiliary cell of the wireless communication system in the method comprises: control terminal of in the main cell and the at least one auxiliary cell initiates a random access process; random access failure detection execution random access process of the terminal determining whether in the primary cell or the at least one auxiliary cell detecting the random access failure and according to whether the detected random access failure result to determine whether to continue the random access procedure.

A random access procedure control method and apparatus is provided for controlling a random access procedure efficiently in a mobile communication system supporting carrier aggregation. The method for controlling random access procedure of a terminal in a wireless communication system having a primary cell and at least one secondary cell includes initiating a random access procedure in the primary cell and the at least one secondary cells detecting a random access failure of a terminal performing the random access procedure determining whether the random access failure is detected in the primary cell or the at least one secondary cell and determining whether to continue the random access procedure according to a result of the determining of whether the random access failure is detected.
