H-RNTI allocation method under CELL_DCH state

The invention discloses a distribution method of H-RNTI at a no CELL_CH state, wherein network side broadcasts the space interval partition of beaconing-channel measured value in subdistrict system information and common high-speed downlink shared channel radio network transaction identifier (H-RNTI) corresponding to each space interval; and a user facility reports the self beaconing-channel measured value to the network side, the user facility/the network side gets common H-RNTI according to the beaconing-channel measured value and carries out the sending-receiving of high-speed downlink shared channel HS-DSCH with the H-RNTI. The distribution mechanism of the common H-RNTI provided by the invention can indirectly play the function of improving the open-cycle power control in the CELL_FACH increasing technology and effectively inhibits the interference to subdistrict users.
