The present invention relates to a method for implementing a traffic generator for measuring processing capacity by call type and function in a number translation processor of an electronic switching system.

Sudden excessive call volume and system failure in the electronic switching system that provides various services to subscribers by the accumulated program control method causes serious failure of the entire switching network by overloading not only its own switching system but also the adjacent switching system forming the network. In addition to system capacity, the system's processing power per unit time is a major consideration in system design.

Therefore, in order to provide efficient service to subscribers even in case of sudden traffic congestion and failure of some systems, it is necessary to measure the traffic throughput of the processor to predict and analyze the maximum traffic that the system can handle per unit time in the system design stage. The implementation of any traffic generator is essential.

Therefore, in the system design stage, the present invention predicts the maximum traffic that the processor can process per unit time by randomly generating the same traffic generated by the subscriber in actual field operation and applying traffic to the processor. In order to protect the network and provide high-quality services to subscribers by analyzing the system traffic processing capability beyond the target by analyzing at the system implementation stage, a traffic generator for measuring the traffic processing capability of the number translation processor in the electronic switching system is implemented. The purpose is to provide a way to.

In order to achieve the above object, the present invention, the first step of processing the input data for each call, such as the home call, outgoing call, incoming call and relay call by examining the test method input from the tester; A second step of processing the input data for each function such as station number translation, caller number translation, occupancy line release and release, incoming call processing after performing the first step; A third step of verifying the data input from the tester after performing the second step, storing the input data if normal, processing the error if there is an error, and ending; A fourth step of driving the traffic generation period timer and the generation time timer after the third step is performed, generating traffic for each call and function input by the tester, and updating the counter according to the received result after the traffic is executed; And in the fourth step, requesting a timer for waiting for the traffic result to be driven, and receiving a release request signal, outputting the traffic result to the tester, and initiating and terminating the input traffic generation data. It features.

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

1 is a schematic diagram of a combination of an electronic switching system and a software functional block associated with the present invention. In FIG. 1, an access switching subsystem (hereinafter referred to as an ASS), and (2) a connection network subsystem ( Interconnection Network Subsystem (hereinafter referred to as INS), (3) Access Switching Processor (hereinafter referred to as ASP), (4) Number Translation Processor (hereinafter referred to as NTP), (5) Is a software subsystem that handles number translation and routing (NTS), (6) Number Translation Block (NTR), and (7) routing and network management functions. Denotes a software block (hereinafter referred to as RCO) for controlling the data in real time.

ASS (1) is equipped with subscriber and relay line matching, various signaling devices, time switch, etc. performs most call processing functions and self-maintenance functions and has a horizontally distributed structure. Up to 63 ASS (1) can be mounted throughout the system.

INS (2) is located at the center of the system and performs the function of connecting the ASS (1) to each other. Space switch is located here. In addition, it performs the space switch connection function among the call processing functions, and is also responsible for generating and supplying a system clock with a network synchronizer device.

The hardware to which the present invention is applied is an ASP (3) in ASS (1), which is equipped with a traffic generator program for testing by call type or call function and performs number translation of NTS (5) belonging to NTP (4). NTR (Number Translation) block (6) and RCO (Route Control) block (7) which performs routing function send / receive each other and perform control function to measure traffic processing capability of NTP (4) processor. Here, the NTR block 6 performs a station number translation and an incoming translation function for acquiring a public telephone network number system and searching for a location of a caller and a called party. The RCO block 7 performs routing functions such as occupying and releasing outgoing line and incoming call processing.

2 is a processing flowchart for processing input data by door and function to measure traffic processing capability of the number translation processor.

When the tester performs this after the traffic processing capacity measurement program is loaded in the ASP 3, the tester requires the following data input to measure the traffic processing capacity of the desired NTP 4.

First, a period for generating traffic is requested (200). The period must be a multiple of 4ms in relation to the clock of the processor, theoretically up to infinite time but typically less than 1 hour with 4ms as the minimum unit. Also, in order to calculate the processing capability of the busy hour, the number of traffic 201 to be generated in one cycle and the traffic generation time are requested 202.

Examine the test method to determine whether the test method to be performed by the tester is a door-to-door test or a function-specific test (203). ), The number to be called (205) and the number (206) for the translation of the station number, the call number (207) for the home and outgoing call requests the incoming line number (207) for the incoming call and relay call The input of processing result waiting time is required in consideration of a signal propagation delay time due to a temporary occurrence of traffic.

If the test method to be performed by the investigator is a function-specific test, the function to be tested is examined (209). If the station number is translated, the number (210) for the station number translation (210), the station number (211) to perform the number translation, and the calling number (212) If the function to be tested is called number translation, the number of incoming digits 213 is requested (214) and the calling number (215), and the input of the ASP (3) number to be called is requested (216).

If the function to be tested is occupied / released by the incoming line, it is required to input the route number for occupying the outgoing line (217) .If the incoming line processing function is requested (218), the incoming line number is obtained by requesting the incoming line number. In consideration of the signal propagation delay time caused by the temporary occurrence of the traffic, input of the processing result waiting time is required (219).

Upon completion of the door-to-door and function-specific data input, the input value is verified (220). If the input data is normal, the input data is stored (221), and if there is an error in the input data, error processing (222) is terminated.

3 is a signal processing flowchart for measuring the traffic processing capability of the number translation processor.

The signal 300 requesting the traffic generation period timer driving and the signal 301 requesting the traffic generation time timer driving are sent to the operating system (OS) and repeatedly generate the traffic for each door and function input by the tester during the traffic generation cycle. The function is executed 302 and the counter is updated 303 by function and by function according to the result.

Receiving the traffic generation time timer release signal from the OS 304, the signal 305 for requesting the release of the traffic generation period timer and the signal 306 for driving the standby timer as a result of the traffic execution are sent to the OS and the Update the execution result.

When the traffic performance result wait timer release request signal 307 is received from the OS, the traffic performance result is output 308 to the tester, and the input traffic generation data is initialized (309) and terminated.

Therefore, the effects of the present invention performed with the above-described processing procedure are as follows.

Sudden excessive call volume and system failure in the electronic switching system with accumulated program control system can cause serious failures not only in the self-exchange system but also throughout the switching network. The implementation of any traffic generator to measure the processor's traffic handling capability was a particularly important consideration in order to predict and analyze the maximum amount of traffic the system could handle per hour during the system design phase.

Particularly, all calls that exist and occur in the entire system are necessarily processed, so the number translation processor, which must be concentrated, predicts and analyzes the maximum traffic that the system can handle per unit time, resulting in excessive call volume and system failure. It is effective in maintaining high quality service to subscribers even in abnormal traffic conditions caused by such traffic lights.
