METHOD FOR IDENTIFYING SOURCE OF ABNORMALITY, SYSTEM OPERATION METHOD, BASE STATION CONTROL SYSTEM OPERATION METHOD, AND PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To switch between an active system and a standby system more reliably than before.;SOLUTION: A base station control apparatus 1 comprising an ACT system common processing device 31 and ACT system subordinate processing devices 41 to 44 is provided with an SBY system common processing device 32 as a standby for the ACT system common processing device 31. If the ACT system common processing device 31 detects a device having abnormality in the ACT system subordinate processing devices 41 to 44, the processing of the ACT system common processing device 31 is handed over to the SBY system common processing device 32. If the SBY system common processing device 32 later detects a device having abnormality in the ACT system subordinate processing devices 41 to 44 and the device is identical to the device detected by the ACT system common processing device 31, the device is identified as the source of abnormality.;COPYRIGHT: (C)2008,JPO&INPIT
