Random access probe transmitting method and apparatus

The invention discloses a transmiting method for random access probe, the method comprises following steps: the first step, dividing random access probes into different priority according to specific factors; the second step, the mobile terminal determines the priority of present random access probe which is used for starting random access; the third step, the mobile terminal sets correlation parameters for transmiting present random access probe according to the priority thereof. Moreover, the invention discloses a transmiting device for random access probes. The invention can improves the access efficiency when multiuser is accessed random, guaranteens QoS of different services in different communication environment.
