RANDOM ACCESS METHOD AND SYSTEM THEREOF

摘要

A random access method is disclosed, which includes the following steps: a benchmark back-off time is pre-configured in a Machine Type Communication User Equipment(ME) or the benchmark back-off time is sent to the ME by a network side, and an adjustment factor is sent to the ME by the network side; the ME adjusts, using the adjustment factor, the benchmark back-off time to obtain a special back-off time, and sends a random access request according to the special back-off time when the ME reinitiates the random access. A corresponding system is also disclosed by the present invention. The present invention enables the ME and a Human to Human(H2H) terminal to use differentiated back-off time for reinitiating random access process, thus resolving the problem of network congestion led by using the same back-off time by the H2H terminal and the ME.
