Accordingly, the MSDP 84b1 requests transmission of the collected data to the PSGL 78a2 of the INS 78 in units of one hour (step 102), and in response to the request, the PSGL 78a2 transmits the MSLC ( 78a2) transmits a request for transmission of data collected in units of one hour, and inquires the collected data for one hour in the MSLC 78a2 (step 103). 78a2) (step 104).

Then, the PSGC 78a2 transmits and reports the corresponding one-hour collection data to the MSDP 84b1 of the OMP 84b (step 105). The MSDP 84b1 receiving the one-hour collection data is reported. While storing the one-hour collection data in the MT / DK (84b2) of the OMP (84b) (step 106), and transmits the one-hour collection data to the MC (84a1) of the MMP (84a) The collected hourly data is windowed at the MC 84a1 and applied to the OC 84a3, so that the measurement result for the one-hour VLR is output through the OC 84a3 (step 107).

In addition, the MSDP 84b1 of the OMP 84b accumulates corresponding hourly collected data in a daily database that stores VLR data on a daily basis (step 108).

Subsequently, as shown in the attached flowchart of FIG. 5, the MSDP 84b1 is a timer built in the OS 72a3 of the ASP 72a1 to check the measurement result for the VLR on a daily basis. When the daily measurement result output time is inquired, the timer inquires the daily measurement result output time based on the time data that is displayed, and reports the inquiry result to the MSDP 84b1 (step 110).

The MSDP 84b1 determines whether the output time of the daily measurement result has been reached based on the inquiry result report (step 111), and if it is determined that the output time of the daily measurement result has not been reached in the step (step 111) ( NO) in step 111), and if it is determined that the output time of day unit is reached (YES in step 111), the MSDP 84b1 is based on the VLR data stored in the embedded daily database. The measurement results of the VLRs per day are recorded in the MT / DK 84b2 of the OMP 84b (step 112), and the measurement results of the VLRs of the MMP 84a are stored in the MC 84a1 of the MMP 84a. As the measurement result of the daily VLR is windowed from the MC 84a1 and applied to the OC 84a3, the measurement result of the daily VLR is output through the OC 84a3 (step). 113).

In addition, the MSDP 84b1 of the OMP 84b accumulates the corresponding hourly collected data in a daily database that stores VLR data on a daily basis (step 114).

Subsequently, as shown in the attached flowchart shown in FIG. 6, the MSDP 84b1 is a timer built in the OS 72a3 of the ASP 72a1 to check the measurement result for the month-by-month VLR. When querying the output time of the monthly measurement result, the timer inquires the output time of the one-month measurement result based on the time data displayed and reports the inquiry result to the MSDP 84b1 (step 120).

The MSDP 84b1 determines whether the output time of the one month measurement result is reached based on the inquiry result report (step 121), and if it is determined that the output time of the one month measurement result is not reached in the step (step 121); In step 121, if it is returned to the initial state, while it is determined in the step that the month output time has been reached (YES in step 121), the MSDP 84b1 is stored in the VLR data stored in the built-in 1 month database. On the basis of the measurement results of the one-month VLR in the MT / DK 84b2 of the OMP 84b (step 122), the measurement results of the one-month VLR are stored in the MC of the MMP 84a. 84a1), the measurement result for the one-month VLR is windowed from the MC 84a1 and applied to the OC 84a3, and the measurement result for the one-month VLR is output through the OC 84a3.

The MDSP 84b1 transmits a statistical measurement start request signal for the VLR to the PSGL 78a2 of the INS 78 (step 131).

Subsequently, the PSGL 78a2 generates a child processor for data collection (step 132) in response to the request to start statistical measurement on the VLR (step 132). In step 72a2, the initial collected data is queried (step 133), and the initial collected data queried in the MSLC 72a2 is transmitted to the PSGL 78a2 and stored in the PSGL 78a2 (step 134).

Then, the PSGL 78a2 transmits a response signal for the measurement start request for the VLR to the MSDP 84b1 of the OMP 84b (step 135). The MSDP 84b1 receiving the response signal is transmitted. Drives the one-time measurement period notification timer built in the OS 72a3 of the ASP 72a1 (step 136), thereby operating the one-time measurement period notification timer.
