Abstract

A pseudosimulation of signals,invention refers to measurement of characteristics of electronic commutation system and can be used for stable generation of load signals in response to boomerang signal. All load signals are generated in the course of each unit time interval is less than limit number of load signals which tested processor can process. But if number of load signals that should be generated in the course of each mentioned unit time interval would exceed limit number than load signals will be generated in amount equal to limit number and boomerang signal will be generated. The rest of load signals will be generated then after reception of mentioned boomerang signal.

Description

The method of generating load signal using boomerang technique

Technical field

The present invention relates to for the pseudo-load box of measuring the electronic switching system (ESS) performance, more particularly, relate to a kind of method that produces for the load signal of measuring the electronic switching system (ESS) performance of in the unit interval, stablizing.

Background technology

Pseudo-load box (or simulation program) is a software program, and the sub-switching system of powering is usually used.This pseudo-load box produces a series of false signals in the regular hour, with the restriction of measuring system capability and the bottleneck of analyzing switching system.According to measuring and analysis result, operating personnel can improve the overload situations of the performance and the control system of system.

Usually, pseudo-load box regularly produces the load signal of timing signal and some in the unit interval.For example, whether can handle 100 incidents by per second for confirming the processor in the switching system, pseudo-load box per second simultaneously produces 100 load signals.The most important is that for steadily measuring the performance of switching system, pseudo-load box produces load signal equably.Therefore, pseudo-load box produces 10 load signals or per 10 milliseconds of 1 load signals for preferably per 100 milliseconds simultaneously, rather than 100 load signals of per second.In fact, [for example, TDX (time-division switching) system] upper strata processor is to work by 40 milliseconds unit interval to general electronic switching system (ESS), but different with the difference of switching system type.Therefore, in order to identify switching system effectively, preferably per 40 milliseconds produce 4 load signals.Can fulfil the step that produces 4 load signals repeatedly when in the case, employed algorithm has timing signal for generating at every turn in the unit interval.Yet, if generally being housed, the electronic switching system (ESS) processor repeat fulfillment of pseudo-load box produces number of times that load signal repeats with the step of handling a lot of more incidents when too much, may produce following some problems.

At first, the load signal that pseudo-load box produces is stored to such an extent that too much line up, or the signal storage that outside processor sends gets up to line up, thereby signal queue is overflowed.Like this, the software of processor may unexpectedly enter init state.

Secondly, though for avoiding signal queue to overflow load limitations in limiting value, thereby being added to that test may increase fast with the load of processor can the generation bottleneck under opposite extreme situations.

Moreover the timing signal that incident that other processor requires or the operating system relevant with timer produce can not store the formation signal queue in the time inner control and the processing of expection, thereby hinders the normal running of switching system.

In addition, if other incident of abort is handled the problems referred to above, may be difficult to accurately measure the performance of electronic switching system (ESS).

Summary of the invention

Therefore, thus the purpose of this invention is to provide a kind of usefulness steadily produces the method that load signal is accurately identified the Electronic Switching System performance from returning technology.

According to one aspect of the present invention, the present invention produces load signal in having the electronic switching system (ESS) of a plurality of processors method comprises the following steps: then to produce all load signals if the load signal that produces in the time per unit lacks with the limiting quantity of the load channel of handling the function processing than test in time per unit; As if the described limiting quantity that outnumbers of the load signal that produces in every described unit interval, then the load signal of generation and described limiting quantity as much and generation are from returning signal; Receive described remaining load signal that when returning signal, produces.

Can more be expressly understood above and other objects of the present invention, characteristics and advantage from the detailed description of embodiments of the invention being done below in conjunction with accompanying drawing.In the accompanying drawing:

Description of drawings Fig. 1 is the block diagram of general No. 7 common channel signaling systems;

Fig. 2 a and 2b are the flow charts that most preferred embodiment of the present invention produces load signal;

Describe most preferred embodiment of the present invention in detail referring to accompanying drawing below the embodiment.

Referring to Fig. 1.No. 7 general common channel signaling systems comprise network (or P bus) 20, user side's processor 10 and a pair of Signal Terminal controller 30.Each Signal Terminal processor 30 is made up of the CPU (CPU (central processing unit)) 34 and the Signal Terminal plate 36 of P bus control unit 32, tape timer.Each Signal Terminal controller 30 all on same back plate, so that share load under normal condition, is controlled the signal link of faulty component when a Signal Terminal controller 30 is out of order therein.P bus control unit 32 makes P bus and Signal Terminal controller 30 cooperatings under the control of CPU34.The whole operation of CPU34 control signal terminal control unit 30.User side's processor 10 is equipped with pseudo-load box of the present invention, so that produce the load signal of some in the unit interval.In addition, user side's processor 10 also is equipped with executive software, other functional software and the user function executive software of carrying out No. 7 common channel signalings.

Describe operating process of the present invention in detail referring to Fig. 1, Fig. 2 a and 2b below.

At first, the pseudo-load box in user side's processor 10 is examined the environment set parameter of whether receiving from the user in step 40.If receive the environment set parameter, then pseudo-load box requires operating system (OS) to set the hardware and software environment in step 42.Above-mentioned parameter has been determined unit interval and the semaphore that produces the unit interval planted agent, to measure the performance of electronic switching system (ESS).Then, pseudo-load box examines whether receive the environment set result in step 44.If receive the setting result, pseudo-load box regularly produces timing signal in step 46.But if do not receive the environment set result, pseudo-load box just produces error signal in step 45, and finishes this program.Then, in step 48, pseudo-load box is confirmed the load signal amount that should regularly produce, and examines the load signal amount that regularly should produce in step 50 and whether be less than a fixed number, for example 5.Self-evident, quantity " 5 " can be by the type change of electronic switching system (ESS).In other words, quantity " 5 " can make the treatable load signal limiting quantity of upper strata processor into.Like this, if the input signal amount of receiving from the user in step 40 is less than 5, pseudo-load box just produces all load signals in step 52,54 and 56 successively.But if the semaphore that should regularly produce surpasses " 5 ", pseudo-load box just will store above the semaphore (being the signal of Board Lot) of " 5 " in step 60.For example, if the semaphore that regularly should produce is 8, then pseudo-load box storage surpass the upper strata processor 3 load signals of treatable limiting quantity 5.

Meanwhile, pseudo-load box successively by

step

62,64 and 66 set by step 52 to 56 same modes produce 5 load signals.If 5 load signals produce in step 66 fully, pseudo-load box just requires system to produce the individual load signal of its excess-three in step 68.The signal that requires to produce all the other load signals is called from returning signal.Then, that operating system is produced in step 62 and later other routine processes of programming start and with the signal of formation form storage, thus make signal queue become empty.So, can produce other signal and store with the form of formation.But the signal that returns certainly that deposits signal queue at last in sends pseudo-load box to, and in other words, the upper strata processor was handled all loads that pseudo-load box produces.Therefore, receive when returning signal that pseudo-load box passes through step 72 successively to 76 its excess-three of generation load signal, changes step 78 then over to.In step 78, whether pseudo-load box is examined the load signal of identifying the upper strata processor performance and is produced fully.If load signal does not produce fully, program is just returned step 50.But if load signal produces fully, then pseudo-load box just outputs test result and finishes this program.

In sum as can be known, pseudo-load box produces the load signals that the upper strata processor can both be handled that get more.Then, receive that pseudo-load box produces remaining load signal in case signal queue excessively overflows when returning signal.Like this, just can accurately identify the performance of upper strata processor.

In addition, need not other device, pseudo-load box of the present invention just can produce the desirable load signal of numbers of poles.Therefore, the performance of the accurate identification systems of being not difficult and bottleneck, thereby the reliability of raising system.In addition, under the situation of calling out relevant [TUP (telephone subscriber side), ISUP (ISDN user side), MTP (MTP message transfer part)] agreement test, the present invention also can be used as the traffic carrying capacity generator.

Describe in detail with regard to most preferred embodiment of the present invention above, but should know to be understood that the those skilled in the art in present technique field may still belong to the present invention in spirit described in the claims and scope to all changes and/or the modification that the basic principle that the present invention instructs at this specification is done.
