PURPOSE:To improve efficiency for data transmission by using a control channel at a radio base station receiving data from a cable line. CONSTITUTION:By adding the identification code of each radio base station 2 to the head of the transmitting data, the reception strength of the control channel to be transmitted by each radio base station 2 can be detected at a radio terminal station 4. By judging a cell 3, to which the own station belongs, based on the result and informing the cell of the radio base station 2, the data are updated at the inside of radio terminal information storage. Then, the radio base station 2 receiving the information of the change stores it in a radio terminal station information storage part that the radio terminal 4 receiving the information exists in the own cell 3, and it is instructed to the radio base station 2, to which the terminal belongs before, to delete the registration of the radio terminal 4. |
