<p><P>PROBLEM TO BE SOLVED: To solve such problems that when failure occurs in an active system server of a redundant C-Plane and the redundancy switching of the active system server to a standby system server is performed, it is necessary for the standby system server to reconfigure call information based on call data transferred from the active system server, and the reconfiguration is time-consuming. <P>SOLUTION: If a device using a multi-core CPU which processes signaling data is separated from a device which processes user data, the device for processing the signaling data having redundant configuration, and system switching is required from the active system server to the standby system server upon the occurrence of failure or the like in the active system server, the standby server, for reconfiguring call information based on call data transferred from the active system server, parallelizes the reconfiguration processing. Thus, it is possible to reduce a service interruption time, and to achieve highly reliable equipment. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
