Method for performing uplink access in broadband mobile communication system
First Claim
1. A method for a subscriber station to perform re-access to a base station at a high speed in a wireless communication system, in which an access channel is allocated so that the subscriber station and the base station can transmit a message to each other using a code within a predetermined period of time, the method comprising the steps of:
- receiving a request rejection message from the base station including a dedicated code in response to a request message transmitted from the subscriber station to the base station through the access channel; and
re-transmitting the request message according to a contention-free method corresponding to the dedicated code included in the request rejection message.

Abstract
Disclosed is an efficient random access method which enables a subscriber station to gain access to an uplink in broadband mobile communication system including the subscriber station and a base station. The method enables a subscriber station to perform re-access to a base station at a high speed in the mobile communication system, in which an access channel is allocated so that the subscriber station and the base station can transmit a message to each other using a code within a predetermined period of time, wherein, the method includes the steps of: the subscriber station receiving a request rejection message including a dedicated code in response to a request message transmitted from the subscriber station to the base station through the access channel; and the subscriber station checking the received request rejection message, and re-transmitting the request message in a contention-free method corresponding to the dedicated code which is included in the request rejection message.
