First, if the MSDP 84b1 embedded in the OMP 84b of the CCS 84 drives the timer for every hour notification built in the OS 72a3 of the ASP 72a1 (step 100), the above When the timer performs the clocking operation and reaches the hourly result, the hourly notification signal is transmitted to the MSDP 84b1 (step 101).

Accordingly, the MSDP 84b1 requests transmission of the collected data to the PSGC 72a4 of the INS 78 in units of one hour (step 102), and in response to the request, the PSGC 72a4 receives 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), and then collects the collected data for one hour according to the inquiry result in the PSGC ( 72a4) (step 104).

Then, the PSGC 78a2 transmits and reports the corresponding hourly collected data to the MSDP 84b1 of the OMP 84b (step 105), and the MSDP 84b1 that has received the hourly collected data is reported. Stores the measurement result of the hourly handoff in the MT / DK 84b2 of the OMP 84b (step 106), and simultaneously stores the measurement result of the hourly handoff of the MMP 84a. It transmits to the MC (84a1), and outputs the measurement result of the one-hour handoff to the operating terminal through the OC (84a3) of the MC (84a1) (step 107).

At the same time, the MSDP 84b1 of the OMP 84b accumulates the measurement results for the corresponding one-hour base station controller in a daily database that stores the measurement results for the corresponding handoff on a daily basis (step 108).

Subsequently, as shown in the accompanying flowchart of FIG. 5, the MSDP 84b1 uses a timer built in the OS 72a3 of the ASP 72a1 to check the measurement result for the daily handoff. When the daily measurement result output time is inquired, the timer inquires the daily measurement result output time based on the time data which 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, while returning to the initial state, while determining that the output time has been reached in one day (YES in step 111), the MSDP 84b1 is stored in a built-in one-day database. On the basis of the data according to the result of the measurement, the measurement result of the daily handoff is recorded in the MT / DK 84b2 of the OMP 84b (step 112), and the measurement of the daily handoff is performed. By transmitting the result to the MC 84a1 of the MMP 84a, the measurement result for the daily handoff is windowed by the MC 84a1 and the OC 84a3 and outputted through the OC 84a3 (step) 113).

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

Subsequently, as shown in the attached flowchart shown in FIG. 6, the MSDP 84b1 uses a timer built in the OS 72a3 of the ASP 72a1 to check the measurement result of the monthly base station controller. When querying the output time of one month unit measurement result, the timer inquires the output time of one month unit measurement result based on the displayed time data 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 NO) is returned to the initial state, and in the step it is determined that the output time of 1 month unit is reached (YES in step 121), the MSDP 84b1 is stored in a built-in 1 month database. On the basis of the data according to the result of the measurement, the measurement result of the monthly handoff is recorded in the MT / DK 84b2 of the OMP 84b (step 122), and the measurement of the monthly handoff is performed. By transmitting the result to the MC 84a1 of the MMP 84a, the measurement result for the one-month handoff is windowed at the MC 84a1 and the OC 84a3, and the base station controller is controlled through the OC 84a3. The measurement result is output (step 123).

The MDSP 84b1 transmits a data measurement request signal for handoff according to the MMC instruction to the PSGC 72a4 of the ASS-W 72a (step 131).

The PSGC 72a4 then initiates data measurement for the handoff in response to the request and then generates a child processor for data collection (step 132), through which the MSLC of the ASP 72a1 is located. After querying the initial collected data at 72a2 (step 133), the MSLC 72a2 transmits the initial collected data to the PSGC 72a4 and stores it (step 134).

Thereafter, the PSGC 72a4 transmits a response signal for the data measurement start request for handoff to the MSDP 84b1 of the OMP 84b (step 135), and the MSDP 84b1 receiving the response signal is received. ) Drives the one-time measurement period notification timer built in the OS 72a3 of the ASP 72a1 (step 136), thereby causing the one-time measurement period notification timer to be driven so that the OS 72a3 starts the operation. One measurement period is notified to the MSDP 84b1 (step 137).

Subsequently, when the MSDP 84b1 requests the transmission of the collected data according to the data measurement for the handoff collected through the steps 133 to 134 to the PSGC 72a4 of the ASP 72a1 (step 138). The PSGC 78a2 inquires the final collected data from the MSLC 72a2 of the ASP 72a1 (step 139), applies the inquiry result to the PSGC 72a4, and stores the final collected data in the PSGC 72a4. (Step 140).

Thereafter, the PSGC 72a4 transmits and reports the collected data through the steps 138 to 140 to the MSDP 84b1 of the OMP 84b, whereby the MSDP 84b1 reports the transmitted data. At the same time as the MT / DK 84b2 is stored (step 142), it is applied to the MC 84a1 of the MMP 84a. The MC 84a1 then window-processes the data measurement result for the corresponding handoff. The data measurement result of the windowed handoff is applied to the OC 84a3 to output the data side result of the handoff to the operation terminal through the OC 84a3 (step 143).

Here, through the operation terminal, information on the network type to be measured, the measurement start time, the measurement period, the measurement repetition count, the reason for abnormal performance, the ASP number, etc. / The number of times lost due to timeout reasons / Lakes lost due to invalid cells / Incomplete lakes due to mobile subscribers / Lakes lost due to lack of public resources / Lakes failed due to system failure The data measurement result for the handoff is output.

First, the MMC instruction, for example, 'Canc-Exe-Cmd' according to the measurement stop request for handoff from the operator inputted through the EC 84a2 of the MMP 84a, is transferred to the MDSP 84b1 of the OMP 84b. When entered (step 150), the MDSP 84b1 transmits a measurement stop request signal for handoff to the PSGC 72a4 of the INS 78 (step 151).

Subsequently, the MDSP 84b1 receives the data measurement result of the handoff applied from the PSGC 72a4 to the MT / DK 84b2 until immediately before the corresponding MMC command is input (step 152). The data measurement result of the off is applied to the MC 84a1, and the data measurement result of the handoff is output to the operation terminal side through the OC 84a3 (step 153).

9 is a flowchart for explaining a method of outputting measurement status information by an operator request among measurement and statistical methods for a base station controller in a personal communication switching system according to an exemplary embodiment of the present invention.

First, the MMC command, for example, 'Dis-Exe-Cmd' according to the data measurement status information output request signal for handoff from the operator inputted through the EC 84a2 of the MMP 84a, is the MDSP of the OMP 84b. If inputted to 84b1 (step 160), the MDSP 84b1 reads the data measurement result for the handoff stored in the embedded database and applies the data measurement result to the MC 84a1 to apply the OC 84a3. The measurement state of the handoff is output to the operation terminal side (step 161).
