Abstract

An apparatus and method for random access in a wireless communication system are provided. In the method, a random access response message is received. The random access response message is analyzed to determine a status of a random access process. A count variable value is updated according to the status. And the count variable value is compared with at least one reference value to determine a random access period. By adaptively changing the period of periodic ranging in a wireless communication system, the probability of success is increased while the waste of resources is decreased.
