<p>A random access method and the device thereof, the method includes that: a user device receives an access indication message(101) including a user device identifier and the corresponding resource number; by using the uplink resource corresponding to the resource number and the preset initial transmitting power, a dedicated physical control channel (DPCCH) preamble is transmitted(102); if an acquisition indication is determined to have been received, then the user device is determined to succeed in accessing(103). By the method, the user device firstly transmits DPCCH preamble to the base station, the success in accessing is determined while receiving the acquisition indication from the base station and the uplink transmission including uplink dedicated physical control information, uplink data and/or feedback information is performed after the success in accessing. Therefore, the reliability of information transmission is ensured, the delay during accessing process is reduced and the fast implementation of uplink search is guaranteed.</p> |
