Below be demonstration with the OMC traffic performance test of CDMA2000, said method is described in detail, not as qualification of the present invention.As shown in Figure 5, may further comprise the steps:
Step 510, comparison module are written into traffic model template commonly used, and traffic model to be tested is set, and the traffic model to be tested that is provided with is synchronized to the analogue network element module;
In the present embodiment, traffic model to be tested comprises: the 1X business is 10000 Ireland, the DO business is 10000 Ireland, when traffic model to be tested is set, comparison module is provided with the relevant parameter of this traffic model to be tested, as every sector users number and contained fan number, can not be provided with yet, and adopt default value.If the relevant parameter that is provided with then when being synchronized to the analogue network element module, is also given the analogue network element module with set parameter simultaneously synchronously.
The traffic template is meant and has comprised one or more traffic models, and the template of the pairing reference performance index of each traffic model.
For example traffic model is: during 1X speech business 10000ERL, the reference performance index of this traffic model correspondence comprises:
Reference performance index when type of service is " signaling tracing ": 200/second of the speed of falling in lines, 200/second of the speed of falling out, 0/second of obstruction speed abandons 0/second of speed, cpu busy percentage 10%, memory usage 300M;
Reference performance index when type of service is " unusual probe ": 50/second of the speed of falling in lines, 50/second of the speed of falling out, 0/second of obstruction speed abandons 0/second of speed, cpu busy percentage 2%, memory usage 50M.
Similarly, when traffic model was DO data service 10000ERL, its corresponding reference performance index comprised: the reference performance index when reference performance index when type of service is " signaling tracing " and type of service are " unusual probe ".
Step 520 is provided with the report output form;
Be provided with in the report generation module, it is HTML that the report output form is set in the present embodiment.
Step 530, the staff opens the debug switch of OMC communication module by the FTP service of login OMC, and it is the traffic model test that debug-type is set;
Step 540, OMC client terminal start-up signaling tracing business is by specifying signaling type to follow the tracks of; And open unusual probe reporting service, and sending the corresponding business operational order, this business operating instructions can be transmitted to the analogue network element module by the communication module of OMC server;
The OMC client mainly is responsible for the related service operation, and the OMC client does not change to some extent because of the OMC server has increased the call test function.
Step 550, after the analogue network element module receives business operating instructions, to be tested traffic model and the true foreground service logic synchronous according to comparison module, simulate (for example 200/second of respective counts magnitudes, relevant with the selection of traffic model) signaling data and/or business datum, send to the communication module of OMC;
Step 560, after communication module receives the data flow of analogue network element module, press the different business of OMC server registration, save the data in the buffer area (being communication module message queue shown in Figure 4) of signaling tracing respectively, and resolution data, again by the type of service tissue, send to corresponding business application service (for example OMC signaling tracing application service), with current OMC system performance parameter: the message rate of falling in lines in the buffer queue, the message rate of falling out, speed is blocked in formation, queue message abandons speed, the CPU usage of OMC, and the memory usage of OMC etc. records in the OMC system performance parameter original document;
Step 570, comparison module is after call test finishes, the OMC system performance parameter of communication module record and the reference performance index of traffic model correspondence to be tested are compared automatically, the comparative result of current performance parameter is generated the file of statistics and comparative result;
If the historical performance parameter is arranged, then can compare the historical performance parameter simultaneously based on the reference performance index, generate historical performance parameter comparative result, and this historical performance parameter comparative result is write down the into file of this statistics and comparative result.
After step 580, comparison module relatively finished, the report generation module was written into comparative result, generate set form analysis report.
The business that present embodiment is tested is only given an example for a kind of, can not be as limitation of the invention.
The present invention has introduced a kind of brand-new traffic model measurement direction: from mobile communication network operating and safeguard angle, according to different traffic models, test transmission data are to the OMC performance indexes.
