Abstract:
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.
