As by the common method of averaging, first group of G1 tested 103 times, and calculating average connecting time is 0.818s; Second group of G2 tested 105 times, and mean value is 0.816s.
Outwardly two groups difference is little as a result, even second group connecting time also is slightly less than first group, but according to the present invention describing method, be the time period with 0.05s, make the contrast histogram, as shown in Figure 2.
Analyze histogram and can obtain following conclusion:
On the one hand, the call duration of 70.47% (28.57%+41.90%=70.47%) is concentrated the segment that has fallen into 0.75s-0.85s among the G1, and the segment of 0.75s-0.85s among the G2, the call duration that but has only (18.10%+16.19%)=34.29%, so first cluster network stability will be significantly better than second;
On the other hand, if with maximum connecting time is that 0.85s exceeds, the test result of 86.66% (5.71%+10.48%+28.57%+41.90%=86.66%) is all less than 0.85s among the G1, and the test result of having only 60.00% (8.57%+17.14%+18.10%+16.19%=60.00%) among the G2 is less than 0.85s.Therefore overall cluster multi call connecting time remains first network and is better than second network.
Can also find out that at last the mean value of G1 is greater than G2 from histogram, reason is to have a test result 2.048 to be exceptional value among the G1, causes G1 mean value higher, and analyzes from histogram, just can avoid the interference of this exceptional value to analysis result.
In addition, also need to prove, above-mentioned preset time scope need guarantee the percentage M addition of each time period in this time scope, and the percentage M sum that must guarantee one group of test data wherein in two or more sets test datas is greater than 50% and less than 100%.This is that the distribution of results greater than 50% just has comparative sense in the statistical test data owing to having only, but can not be 100%, because all percentage M sums of which group all are 100%.With Fig. 2 is example, if get the time range of 0.65-0.75, second group on the contrary and (8.57%+17.14%)>first group and (5.71%+10.48), but because 8.57+17.14=25.71%, this value is less than 50%, so not representative, and the scheduled time scope of for example getting 0.75-0.85 is exactly suitable, it has guaranteed that one of them group test data M sum is greater than 50% and less than 100%.
More than, only be that example is described in detail the method for testing relay performance of group call of the present invention, but trunked call of the present invention is not limited to group calling, can also comprise individual calling with the group calling, its concrete steps and group calling and indistinction, the present invention is not described in detail.
In sum, method according to testing relay performance of group call of the present invention, fall into the percentage M of each time period by the call proceeding time of calculating different test groups, different test groups in the preset time scope are fallen into the percentage addition of each time period, and result of calculation compared, according to this comparative result, analyze call proceeding speed speed more exactly, thereby determine the network quality; Can also further test result be showed by histogrammic form, can judge stability of network intuitively.
More than be in order to make those of ordinary skills understand the present invention; and to detailed description that the present invention carried out; but can expect; in the scope that does not break away from claim of the present invention and contained, can also make other variation and modification, these variations and revising all in protection scope of the present invention.
