One, selects satisfactory testing tool according to the characteristic of testing requirement and measurand
1, analyzes and selects to satisfy the characteristic of testing requirement instrument
Performance testing tool can be simulated the concurrent a plurality of business of various clients entities, just information receiving and transmitting instrument.Testing tool must be able to be realized the main flow process of client, supports corresponding protocol.Flow process should be customized, configuration can be realized each flow data.Can realize flexible configuration to various flow process ratios.Statistics can be realized, the successful number of failure can be added up at least each checkpoint of each load flow process.To the appointment process or the user can follow the tracks of and to unusually can record.Also have performance of Road test instrument own and capacity will surpass more than three times of tested entity anticipated capability at least, the load instrument must have very strong stability, can handle abnormal conditions, and messaging is followed standard agreement.Its device then is compact more good more, and it is friendly that man-machine interface is also wanted.The commercial tester that can use at present has MGTS (TEKELEC company), calling set (AMERITEC company), 8610 (ACTERNA companies).For the development and testing instrument voluntarily that reduces cost, its basic function must realize that switching network node that is virtually reality like reality carries out a large amount of information receiving and transmittings, has a lot of achievements in this respect.
2, calculate the capacity of measurand and measurand week mid-side node, from the testing tool of the characteristic that can satisfy testing requirement, can satisfy measurand and measurand week mid-side node the testing tool of capacity requirement.
Switching node is not independently in wireless network, to link to each other with other nodes such as BSC, VMSC, GMSC, HLR, SCP etc., if tester can be simulated these nodes and call volume can satisfy the call volume of measurand design capacity more than three times fully strictly speaking, be best with tester so.But in most cases tester all can not replace other node fully, because call volume can be not enough sometimes, link is not enough, dispose not enough etc., so will build surrounding enviroment in addition when testing.So just can the performance that must consider these environment in advance satisfy the test needs.Computational methods are whether the number of users that each node is supported mates with measurand, and perhaps can its configuration satisfy maximum message traffic.As can run into this situation when testing IN service, tester might can't provide the SCP that satisfies test capacity node, and SCP must be with real.The user data of IN service all is placed in the SCP server, and SCP must provide and criticize the function of opening an account during Road test, otherwise can't test.Similarly also have HLR, before with the networking of class database real equipment, all will estimate its performance, can support how many users on earth, great calling strength (BHCA).Often pay close attention to the variation of its CPU during test, in order to avoid because performance issue influence test.If owing to the little test bottle neck that becomes of all mid-side node capacity, troclia point device capacity should take immediate steps.
Two, establishment performance test networking diagram and explanation
The principle of networking is as far as possible near actual beginning situation.Equipment can run into various complicated networkings on the net, under lab can not be fully with online consistent, and also the too complicated meeting of data is to being write test case, and service data makes troubles.At this moment to analyze online data characteristic, targetedly the online situation of simulation as far as possible.In the office direction number, size especially is greater than on the capacity or equals online beginning maximum configured.Sometimes also will consider the variation of initial stage on the engineering, first phase and second phase, transmission circuit can not settle at one go during such as initial stage beginning, and general owning administration is to only opening in first three module, and a part of again circuit is added up.Can not test suite (data of tester) is convenient be done data very even in order to write during networking, and almost bump in the reality less than, and when carrying out limit test, also need jumbo office direction and little office direction.Therefore rendering performance Test Networking figure and numbering will be finished following work: A, determine office direction number, size, carry out the signalling point numbering and the circuit of each office direction or network node, number section, speech channel path, the distribution of resources such as link; B, draw out Test Networking figure, indicate network node by testing tool simulation; The content of C, realization Test Networking figure design in the data configuration of testing tool is with the data configuration coupling of tested equipment, for interoperability test is got ready.
Three, determine traffic model
Traffic model derives from online traffic statistics data, and the long-term statistics to user behavior could the real characteristics that characterize a user of office.The Standard User model that provides in the technical specification is provided substantially for we for the laboratory, and is as follows as the traffic model of the VMSC1 of end office (EO) at one 24 general-purpose family, mobile subscriber's mean time load: 0.03Er1/ user
Average call duration: 60 seconds
Average call attempt: 1.8 times/when hurrying
The position is upgraded: 2 times/when hurrying
Switch (between BSC): 0.5 time/when hurrying
Traffic flow distributes: fixing beating moved 40% and moved to beat and fix 50% and move and beat mobile 10%
The long local telephone network ratio of mobile subscriber: 1: 3
According to operating experience on the telecommunications network of reality, at country variant, different regions, different stages of development, among the mobile network of different purposes, traffic model is distinguishing.Various features can change within the specific limits, and mobile subscriber's mean busy hour load commonly used is generally 0.018-0.03Er1/ user, and this index only refers to the index of calling out with average call attempt following relation is arranged:
Mobile subscriber's mean busy hour load=average call attempt * average call duration (second)/3600.
If this system user capacity is W, average call attempt was T1 when the mobile subscriber was busy, and the position is updated to T2, and switching (between BSC) is T3, fixed in the ratio that telephone traffic is distributed to beat to move to be E1, moved to beat to be fixed as E2, moved and beat the mobile E3 that is.How should we realize this traffic model during so specific to test?
At first mobile subscriber's quantity has determined the capacity of switching subsystem, if this system user capacity is W user, there be W with regard to the mobile subscriber who is meant above standard feature, the main users business that this standard feature takes place when normally being hurried by the mobile network decides, and the number of times that this business takes place when busy just should count much larger than other business. to change into the calling BHCA number of the different type of calls of each office direction of BSC and PSTN during realization.Calculate total BHCA earlier, computing formula is as follows:
The total BHCA of calling order is L, L=W * T1
Total position is upgraded the BHCA order and is M, M=W * T2
The total BHCA of switching order is N, N=W * T3
With the VMSC1 of end office (EO) is example, and result of calculation is
Total calling BHCA is L=240000 * 1.8=432000
It is M=240000 * 2=480000 that BHDA is upgraded in total position
Total switching BHCA is N=240000 * 0.5=12000
Because have different call case under the call business, L is by the traffic flow pro rate, computing formula is as follows,
Fixing mobile BHCA=L * E1/ (E1+E2+2 * E3) that beats
Move and to beat fixedly BHCA=L * E1/ (E1+E2+2 * E3)
Move and to beat mobile BHCA=L * E1/ (E1+E2+2 * E3)
With the VMSC1 of end office (EO) is example, and result of calculation is:
Fix and beat mobile BHCA=432000 * 4/11=157091
Move and beat fixedly BHCA=432000 * 5/11=196364
Move and beat fixedly BHCA=432000 * 1/11=39273
Then according to the ratio of shared calling relaying of each BSC (GSM, CDMA) or the shared call resources of RNC (WCDMA) with M, N, L * 1/11, L * 5/11 is distributed into call volume separately; With the pro rate call volume of L * 4/11 by each PSTN office direction relaying.If require to have the ratio of long local telephone network, then the office direction resource allocation of long local telephone network also will be in proportion, and is enough with the assurance resource.Should be noted that 2 points when calculating traffic matrix:
1, in different regions, different phase is among the mobile network of different purposes, business has very big difference, and following new business is also in continuous increase, might T1, T2, T3 also not exclusively can characterize the main users business, also T4 can occur, T5 etc., and in the test of mobile gateway office T2, T3 does not exist, and only needs to calculate call business T1.T1 general range 1-3.6, T2 general range 2-6, T3 general range 0.5-1.
2, the total L that calls out BHCA of expression is meant all mobile subscribers, comprise calling subscriber and called subscriber, as long as play the calling that just will produce two mobile subscribers when mobile when moving, the total BHCA of calling that can guarantee all mobile subscribers like this is that L. does not have mobilely to beat mobile situation with regard to direct branch in proportion in this way.E1 general range 25-40%, E2-50%, E3 general range 10-45%.
The traffic model that calculates through above method is the standard traffic model, the ordinary circumstance when the equipment online operation is normally busy just, and the comparativity between the representative and product, significant for performance test.
Four, write test suite and debugging
After Road test work launches, should first fixed system test plan estimate the time of cost, if the network that neither one can stable calls, the establishment of preparing environment material, data and tester test data will account for whole at least 1/5 time of test process so.The tester test data also is test suite, and test suite has determined the model that load is called out, type of call, and call volume should clearly be described test suite in test plan.The details of test suite should be noted entirely.
The test suite that writes of debugging should be from single process, transfer logical after debugging load flow process again, at this moment also office direction debugging one by one, and will all run a time to test data up to no problem just can call out the overall situation.
Five, measurand is carried out all-round property testing
All-round property testing comprises following six aspects, and according to the characteristics of different product, concrete operations have difference.Testing performance index, stability test, reliability testing, boundary value test, System Functional Test, maintainability and testability are tested the execution sequence of this six class testings method and can be decided according to actual needs, should all must carry out one time as complete test.Described the test purpose of all kinds of method of testings below respectively, the checkpoint helps to understand method of testing.And illustrate particular content with the test sub-project, be exactly DCO project as shown in Figure 2 to certain product.
