Abstract: A smallcell base station and a channel assignment method for the same are introduced. In response to a connection mode-related service request make by a user equipment (UE) for performing a communication service, a channel assignment processor of the smallcell base provides a forward access channel (FACH) for functioning as a communication route of the UE, assigns to the UE the FACH for functioning as a wireless transmission channel between the smallcell base and the UE in the connection mode when no dedicated channel (DCH) is available, and discontinues other communication services so as to release a DCH to the UE when the communication service has higher priority. Accordingly, the smallcell base need not keep a DCH for use in accessing during the connection mode, thereby making good use of channel resources.
