摘要： Disclosed is a random access method for a machine type communication (MTC) terminal. The random access method performed by a terminal includes performing a cell search, determining a radio environment based on time taken to perform the cell search, and performing different random access procedures depending on the determined radio environment. Accordingly, coverage of the MTC terminal that is in a poor radio environment may be enhanced, thereby performing normal communication with a base station.
