Abstract:
1. A method for transmitting information through a random access procedure in a mobile communication system, the method comprising the steps of: setting, when the random access procedure is triggered, a cause value according to an object for which the random access procedure is triggered; determining at least one additional information element to be notified through the random access procedure based on a class of the cause from among classes of the cause, and selecting a random access code mapped to the cause and the determined additional information element by referring to a random access code table; and transmitting the random access code to an Evolved Node B (ENB) through a random access channel, wherein, in the random access code table, random access codes belonging to a first class from among the classes of the cause and random access codes belonging to a second class are mapped to different combinations of additional information elements, and first additional information elements from among the mapped additional information elements are mapped with different ranges to the random access codes belonging to the first class and the random access codes belonging to the second class.
