Title: Method for minimizing error of clock data in exchanger system
Inventor: LEE SUNG HYUN
IPC: H04Q1/00
Filed: 1998-12-30
Abstract: PURPOSE: A method for minimizing an error of clock data in exchanger system is provided to send the updated clock data every constant period and to offer the clock data in msec unit of minimum clock unit. CONSTITUTION: A method for minimizing an error of clock data in exchanger system is as follows. A SCM(system clock management block)(151) sends a request message of hardware clock data to a NSP(network synchronization processor)(113) through a CCPI(call control processor interface)(140) every established period. The NSP(113) receives the request message of hardware clock data and sends IRQ(interrupt request message) to a first NSCMA(network synchronization clock management)(115). The first NSCMA(115) send the present hardware clock data stored in a memory 1 to the NSP(113). The NSP(113) checks the present hardware clock data received from the NSCMA(115). If the present hardware clock data is void, the NSP(113) re-sends the IRQ to the NSCMA(115) and receives the present hardware clock data again. If the present hardware clock data is valid, the NSP(113) stores the received present hardware clock data to a memory and sends the clock data to the SCM(151). The SCM(151) sends the present hardware clock data stored to a memory when an OS time management unit(160) requests the clock data to the OS time management unit(160). The OS time management unit(160) receives the minimum unit of clock data and utilizes the clock data in the exchanger system.

If a fault is generated, the exchange operating system stores the collected statistics data in the hard disk of the exchange temporally(S4). The exchange operating system confirms at intervals of a required time whether the communication fault is repaired(S5). If the communication between the exchange side and the operating server side has been repaired to normal condition, the exchange operating system copies the statistics data stored in the exchange hard disk to the hard disk of the operating server(S6). The operating server reads a desired statistics data from the hard disk of the operating server and outputs graphically(S7).
