Abstract

The invention relates to a method and device for testing an IP-PBX (Internet Protocol Private Branch Exchange) load. An interface driven by an IP-PBX bottom layer is used as a test interface; port off-hook, on-hook, port state detection and DTMF (Dual Tone Multiple Frequency) receiving and transmitting of an FXO (Foreign eXchange Office) on the IP-PBX are controlled through the test interface, quantity of call forwarding users is controlled and reverse data is processed according to a preset test progress; and a test progress processing module arranged on a drive layer of the IP-PBX equipment bottom layer is used for carrying out analogue simulation of a phone for constructing a forwarding large telephone traffic and receiving and processing messages and data reversely sent by an entity side to be tested; and by using the interface driven by the IP-PBX bottom layer as a test interface, the whole IP-PBX tested system can be tested. The invention supports function and performance tests on an analog trunk, an IMS/SIP (IP Multimedia Subsystem/Session Initiation Protocol) trunk or E1 trunk, and generates analog call under the condition of no need of support of an additional apparatus, thus the testing cost is effectively lowered.

Description

The method of IP-PBX load testing and device thereof

Technical field

The present invention relates to a kind of method and device thereof of IP-PBX load testing, belong to the convergence communication technical field.

Background technology

In the convergence communication field, always expect the operation that communication apparatus can be steady in a long-term, can withstand the impact of certain telephone traffic simultaneously.

The purpose of load testing is simulated a large amount of Virtual User exactly and is initiated basic call, calls out callings such as forward pass, Three-Way Calling, meeting, alarm clock; Realization is carried out shock test to IP-PBX; Stability with the checking product; From the MTD aspect, can excavate the fault that the general test method can't be found, the working load testing tool is very effective to equipment cpu busy percentage, internal memory optimization, communication effect optimization etc. simultaneously.

Load testing method the most desirable, fullest is controlled a large amount of analog station dislodging machines with instrument exactly, produces Bulk Call.But in actual mechanical process; If use true phone to realize load testing and unrealistic merely, at first be the analog station resource problem, the analog station number can not be expanded; Secondly different people has different customs in the real simulation phone manual test process; Therefore each test result is all variant, can not expect that in addition each test can both add identical load, and so a lot of test scenes all can not reproduce.

Therefore; Come the load test approach of simulates real truth machine to be very important with instrument; Can realize that the most effectively test, important notion of load test approach are exactly the interface division of system under test (SUT) and traffic instrument with the cost of minimum, be referred to as test interface.

The principle that test interface is divided: at first to guarantee testing tool can realize to system under test (SUT) the most effectively, the simulation test of fullest, closing to reality, secondly be the coupling that reduces as much as possible between testing tool and the system under test (SUT).From some method of testings of present announcement, the method test interface that has is too highly fixed, so that the coupling between testing tool and the system under test (SUT) is higher, so just can not realize the abundant test to system under test (SUT); The other method is exactly that test interface Ding Detai is low, though effectively reduce the coupling between testing tool and the system under test (SUT), has but introduced more additional hardware resources, and the cost performance aspect just is affected; From the business of present method of testing realization very little, means of testing is too single in addition.

Therefore, the reasonable definition test interface is the key that realizes load testing, not so can cause the insufficient or expensive phenomenon of test.

Summary of the invention

The objective of the invention is to overcome the deficiency that prior art exists; A kind of method and device thereof of IP-PBX load testing of practicality are provided, though to solve in the existing load test approach because the improper test that causes of test interface definition is insufficient or the abundant too high problem of input cost of test.

The object of the invention is realized through following technical scheme:

The method of IP-PBX load testing may further comprise the steps:

1) with the interface of IP-PBX bottom layer driving as test interface;

2) test interface control IP-PBX goes up fxo port off-hook, on-hook, port status detection, DTMF transmitting-receiving, and according to predefined test process, controls forward direction calling party number, and reverse data is handled.

Further, the method for above-mentioned IP-PBX load testing, step 2) also comprise: judge according to the port numbers that comprises in the forward data whether the forward data of sending is the data of desiring to be sent to said emulation phone, still initiates the data of supplementary service.

Further, the method for above-mentioned IP-PBX load testing is desired forward data to be sent to the data of real simulation phone and is delivered to corresponding real simulation phone or be sent to corresponding SIP phone through network through the RJ11 interface.Forward data is desired to be sent to the data of phone and initiate diversity of operations through type of service control system under test (SUT).

Further, the method for above-mentioned IP-PBX load testing, step also comprises: test interface receives the reverse data from real simulation phone or true SIP phone or analogue simulation phone, and reverse data is handled.

Again further, the method for above-mentioned IP-PBX load testing, said test process is the Protocol Process Unit of the real simulation phone of desire emulation.

The device of IP-PBX load testing of the present invention; The test process processing module resides on the testing apparatus IP-PBX equipment; Be used for the analogue simulation phone; Structure forward direction Bulk Call receives and handles the data that tested IP-PBX oppositely sends over simultaneously, simultaneously this process be used to start test process, in advance be provided with the required test parameter of test process, show current test result.

Substantive distinguishing features and obvious improvement that technical scheme of the present invention is outstanding are mainly reflected in:

The present invention through with the interface of IP-PBX bottom layer driving as test interface, can cover test to entire I P-PBX system under test (SUT).Support can produce analog call, thereby effectively reduce testing cost analog junction, IMS/SIP relaying or E1 relay function and performance test under the situation that does not need the additional instruments support.Support calling simultaneously, thereby effectively increased the diversity of test meeting, calling transfer, Three-Way Calling and real simulation phone.Because this testing tool resides in bottom layer driving, yet bottom layer driving is constant basically, makes that the coupling between testing tool and the system under test (SUT) reduces greatly, effectively reduce the difficulty that testing apparatus is safeguarded.

Description of drawings

Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
