Title:
データ同期方法
Document Type and Number:
Japanese Patent JP5412481
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a data synchronization method capable of quickly restarting (continuing) call processing after system switching.SOLUTION: A data synchronization method comprises: a first synchronization step of starting data resynchronization of a basic region 63B of a new ACT-system call control server 63 for a new SBY-system call control server 64 from the new ACT-system call control server 63 after system switching; a saving step of saving the data generated by a reception signal including a continuation signal for call processing in a temporary region 63A of the new ACT-system call control server 63; and a second synchronization step of starting synchronization of the data saved in the temporary region 63A of the new ACT-system call control server 63 for the new SBY-system call control server 64 from the new ACT-system call control server 63. This method also controls throughput of the new ACT-system call control server 63.
