METHOD OF OPERATING RANDOM ACCESS CHANNEL IN MOBILE COMMUNICATION SYSTEM

摘要

A random access channel operating method in a mobile communication system is provided. The random access channel operating method includes: (a) selecting a transmission mode according to a load of a random access channel and performing transmission to a mobile terminal; (b) receiving a message having a format corresponding to the selected transmission mode from the mobile terminal; (c) determining whether or not a preamble or data is included in the message received in (b) receiving of the message; and (d) if the data is determined to be included in the (c) determining, transmitting a response message for data reception to the mobile terminal. Accordingly, use efficiency of a random access channel can be increased by measuring a system load of the random access channel in a base station and changing a transmission format of a burst transmitted through the random access channel according to the measured load level.
