PURPOSE:To prevent a mobile station from interrupting communication even if all radio channels of a radio base station are in busy by assigning priority to each mobile station in advance and giving the priority to the radio channel of a radio zone of a mobile destination to the mobile station based on the said priority. CONSTITUTION:If a mobile station 5-1 moves from a radio zone 2-3 to a radio zone 2-2, a control station 3 sends a mobile destination decision signal representing that the mobile station 5-1 is moving to the radio zone 2-2 to the radio base station 1-2 having the said radio zone 2-2. Then the control station 3 discriminates whether or not the radio channel of the radio base station 1-2 is idle based on the communication control between the control station 3 and the radio base station 1-2. In case of busy, the control station 3 discriminates to which of the mobile station 5-2 located in the radio zone 2-2 and the mobile station 5-1 moving to the radio zone 2-2 the priority is to be given. Thus, a trouble of interrupting communication without any possibility is avoided. |
