<P>PROBLEM TO BE SOLVED: To provide a recovery processing device and a recovery processing method that detect operation abnormality of a fixed radio station in a radio base station and perform a recovering operation for the fixed radio station on the detection of the abnormality. <P>SOLUTION: When a master operation abnormality detector 21 of a slave control unit 20 detects operation abnormality of a master control unit 10, the slave control unit 20 sends an abnormality detection signal through a serial port line 40 for operation state confirmation and a forcible reset signal through a forcible reset signal line 41 for master to the master control unit 10. Once receiving those signals, the master control unit 10 stops a relaying operation to perform normal recovery processing and also transmits a forcible reset signal to the slave control unit 20 through a forcible reset signal line 42 for slave, and the slave control unit 20 once receiving the signal performs similar normal recovery processing. <P>COPYRIGHT: (C)2008,JPO&INPIT |
