PROBLEM TO BE SOLVED: To allow a radio base station side to continue an operation through self-restoration even when data (including program) downloaded from a host station through data transfer is damaged in the radio base station. SOLUTION: A radio base station 20 is provided with a controlling part 21 which processes data transferred from a host station 10 through interoffice circuits 31 and 32, an original data area 22 which stores data that is currently subjected to an operation, a temporary data written area 23 which stores transferred data, an original data save area 24 which stores data before the data is transferred and a self-restoration information storage area 25 which stores information (date check result in each area, version information and use priority sequence) which is necessary for self-restoration. When the transferred data is destroyed, the base station is operated by using other area storage data. In a self-restoration operation, an operation situation and the version information are notified to the station 10. |
