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 a random access procedure in wireless communication system of main cell and at least one secondary cell control method of terminal comprises: sending a random access preamble on a primary cell or a secondary cell by a terminal; based on sending times of random access preamble by the terminal determining on the main cell sends a random access preamble or a secondary cell random access problem is detected; if the transmitted random access preamble on a primary cell indicating the random access problem to upper terminal and performing radio resource control (RRC) connection re-establishment procedure; and transmits a random access preamble on a secondary cell if stopping the random access procedure.
