And outputting a result of determining whether the total result time is not the intermediate result output time. That is having yirwojyeo a step of outputting a result.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

2 shows a system circuit block of the SSP 10 equipped with a load box 12b according to the present invention.

The SSP (10) is connected to the PS (12, 13, 14) or the PS (12, 13, 14) and the CC (Central Control System 15) connecting the CC (INS; Interconnection) Network System 11), the RS-T (12), which is interconnected with the RS 11, is responsible for matching function for the relay line and call processing other than number translation, and matching function and number translation for analog fixed subscribers. It is connected to the PS-S (14) which is responsible for most call processing, the PS-7 (13) which is responsible for processing the PS-7 signal, and the INS (11) to maintain overall system maintenance. It includes the Sisses 15, which are in charge of maintenance and management functions.

The INS 11 has an INP (Interconnection Network Processor 11a) having a call processing function such as searching for a call path and a maintenance function related to state management such as failure detection and recovery processing of a switch network and block / block release. And an NTP (Number Translation Processor 11b), and the CSI 15 is composed of an OMP (Operation and Maintenance Processor 15a) and an MMP (Man Machine Processor 15b).

In addition, the PS-TS (12), the PS-S (14), the PS-7 (13) to the ASP (Access Switching Processor 12a, 13a, in charge of call flow control and operation maintenance functions, 14a).

In the SSP system 10 as described above, the present invention is equipped with a load box 12b for testing the actual performance and the maximum capacity of the NTP 11b.

The load box 12b is a service call signal handled by the SSP 10, in particular, PSTN (Public Switched Telephone Network), IP PSTN, PLMN (PLMN; Public Land Mobile Network) It is configured to generate a call to the NTP 11b for the IP PMP.

On the other hand, the system is equipped with a method for measuring the entropy performance / capacity of the service performing exchange as shown in FIG.

Here, the load box 12b software block of the system is loaded into the ASP 12a of the S-T 12 of the SP 10, and the number translation type is determined to determine the input value required for the execution of the load box 12b. (Steps 101 to 103), and then the system receives the total generation time / intermediate result output time / call occurrence time / number of call occurrences of the call signal to determine the total occurrence time / intermediate result output time / call occurrence time. A step (step 104, 105) is set in the timer.

Further, the system determines whether the call generation time is later and collects a call generation picture and a call result according to the number translation call type if the call generation time (Stems 106 to 116), and if the call generation time is not the intermediate result output time. Outputting the intermediate result if the intermediate result output time is determined (steps 117 and 118); and if the intermediate result output time is not the above, the total result is determined. Steps 119 and 120 are included.

In the present invention, when the load for the intelligent network call in the load box (12b) is measured by loading the load box (12b) to the ASP (11a) of the S-T 11 as shown in Figures 2 and 7 To be executed (step 101).

When the load box 12b is operated, first, a call generation type input is required, and the types of number translation arcs required are PITIEN, PIMEN, IPPIEN, and IPPMEN (step 102).

Thereafter, when the call is requested, information required for call generation is received from the load box 12b, and the most important information is a number according to the actual call type, and a number generated at the current exchange is input (step 103).

At this time, the types include mobile number, target number, and TDL NTemporary Directory Number.

Subsequently, the total time for driving the load box 12b, the intermediate result time, and the number of occurrences of the call during the call generation time are received (step 104), and the time job registration for the total generation time is registered. Cycle job registration for results and cycle job registration for call generation are performed (step 105).

When the call generation time is reached, the number of calls is generated according to the type of call, and the call generation flow according to the call type is shown in FIGS.

Fig. 3 is a flowchart of the call of PTI, which indicates that the load box 12b sends the number translation request signal WIN PREFIX to the ENTIP 11b dp, and the ENT 11b notifies the intelligent network call, and the load box 12b. When the number translation request signal (target prefix) is sent, the entree 11b provides the outgoing notification signal.

When the entitlement 11b sends the outgoing relay request signal to the load box 12b, the load box 12b0 collects the number of call successes.

4, the load box 12b sequentially sends the number translation request signals WIN PREFIX, MOBILE PREFIX, and TLDN PREFIX to the ENP 11b. The intelligent network notification signal, the mobile call notification signal, and the outgoing notification signal are sent in order, and the outgoing request signal is sent to the load box 12b from the entip 11b, and the load box 12b collects the number of call successes. .

In addition, in the occurrence flow diagram of the IP PTI such as FIG. 5, the load box 12b sequentially sends the number translation request signals WIN PREFIX, TLDN PREFIX, and target PREFIX to the ENTIP 11b. The intelligent network notification signal, outgoing notification signal, outgoing notification signal are sent in order, and the outgoing request signal is sent from the entipe 11b to the load box 12b, and the load box 12b receives the number of successful calls. Collect.

6, the load box 12b sequentially sends the number translation request signals WIN PREFIX and TLDN PREFIX to the ENTIP 11b. In the ENTP 11b, the corresponding intelligent network The notification signal and the outgoing notification signal are sequentially transmitted and received, and when the outgoing request signal is sent to the load box 12b from the entip 11b, the load box 12b collects the number of call successes.

In addition, when the load box 12b sends the MOBILE PREFIX to the entree 11b and receives the mobile call from the load box 12b in the entree 11b, the load box 12b sends the TLDN PREFIX to the entree 11b. If the send box request signal is sent to the load box 12b from the entity 11b, the load box 12b collects the number of call successes.

The process processed according to the call generation flow chart is regarded as one call in the actual intelligent network call, and when the outgoing request signal is received from the load box 12b, it is considered as a call success and the number of successes is counted. It continues to generate until the load box 12b completes (steps 106-116).

In the above, the system outputs the intermediate result time / occurrence number / success number / success number / failure number when the intermediate result time is reached; The contents of the signal names exchanged between the blood and the load box and the total number / load number per hour are output and the load box 12b is terminated (steps 117 to 120).

As described above, by measuring the CUP load of the ENTIFY 11b while operating the load box 12b, it is possible to calculate the capacity that the ENTIFY 11b can handle at the actual site.

In order to verify how the actual performance and maximum capacity of the EntiP is not calculated in the design stage, but the calculation of the EntiP performance and maximum capacity in the design stage of SSP, which is an intelligent network element, Service calls require intelligent calls to generate enough capacity to calculate the maximum capacity, so testing is not possible.

However, in the present invention, the test and measurement functions as described above can be implemented through the load box, and the results calculated through the test and measurement can be used as data for improving the performance of such a system. It can be used as a promotional material for.
