The invention discloses a method for generating a group identifier of the random access response message. The group identifier is determined according to the serial number of the subframe in which the random access time slot of random access preamble message transmitted by the terminal lies and the serial number of the random access channel in which the random access time slot lies. A random access method and a random access response method in a cellular radio communication system are also provided. Using the method of the present invention, the terminal needs not acquire the absolute system time of the cellular system in which the random access time slot lies, and can access the cellular radio communication system rapidly and accurately. |
