The invention discloses an access mode selection method, including: free Idle or CELL access channel to the area before the FACH mode, the probability is scheduled in the mobile terminal is low, start access options. The invention also discloses a method for transmitting uplink data, including: the relevant parameters for sending base station and mobile terminal configuration of the uplink data, or idle area before CELL to access the channel model FACH, probability to be scheduled in the mobile terminal low start access options; select PRACH physical channel resource carrying to be sent when the data will be sent to the data into E DCH TB, by PRACH physical channel resource is sent to the network side. The invention also discloses a device for realizing the two methods. In the case of less uplink data, the PRACH channel is used to carry up uplink data, and the overhead of uplink channel is saved.
