Step 106 obtains that each wireless signal strength section is corresponding to meet preset speech service quality requirement
MOS value；
The specific value that preset speech service quality requires, which can according to need, to be configured, and the embodiment of the present invention is not
It is specifically limited, the present embodiment is carried out by taking the 10th percentage point of corresponding MOS value in each wireless signal strength section as an example
Explanation.
Reference table 5, table 5 shows MOS mean value in each wireless signal strength section and the 10th percentage point corresponding
MOS value.
Table 5
Wherein, the corresponding MOS mean value of wireless signal strength section i: MOSMean value (wireless signal strength section i)=Average (wireless signal
All MOS values corresponding to intensity interval i).The corresponding 10th percentage point of corresponding MOS value of wireless signal strength section i:
MOS10th percentage point of (wireless signal strength section i)=PERCENTILE (all MOS values corresponding to the i of wireless signal strength section, 10%).
Step 107, by with the immediate MOS value institute for meeting preset speech service quality requirement of preset MOS threshold value
Corresponding wireless signal strength Y is determined as the wireless signal strength target value.
The specific value of preset MOS threshold value, which can according to need, to be configured, and the embodiment of the present invention is without specifically limiting
Fixed, the present embodiment is illustrated so that preset MOS threshold value is equal to 3.0 as an example.As can be drawn from Table 5, for each wireless signal
MOS mean value in intensity interval, with the immediate wireless signal strength section of preset MOS threshold value be [- 122.5 ,-
121.5], wireless signal strength section central value corresponding to the wireless signal strength section is -122dBm, can indicate net
Network coverage planning index is that wireless signal strength is more than or equal to -122dBm.Wireless signal is worked as in network coverage planning index expression
When intensity is more than or equal to -122dBm, ratio of the voice quality MOS value greater than 3.0 is about 50%.It is strong for each wireless signal
The 10th percentage point of corresponding MOS value in section is spent, is with the immediate wireless signal strength section of preset MOS threshold value
[- 112.5, -111.5], wireless signal strength section central value corresponding to the wireless signal strength section are -112dBm, can
To indicate that network coverage planning index is more than or equal to -112dBm as wireless signal strength.Network coverage planning index expression is worked as
When wireless signal strength is more than or equal to -112dBm, ratio of the voice quality MOS value greater than 3.0 is more than 90%.
If can be seen that from the analysis result of table 5 and determine network coverage planning index with MOS mean value, to guarantee
Mean value > 3.0 VoLTE voice quality MOS then only need wireless signal strength to be more than or equal to -122dBm, it can be seen that wireless communication
Number covering index request is very low, is to be difficult to meet the voice service of user to perceive if pressing this index planning network.
Further, as shown in figure 3, step 103 can also be substituted with step 108-111:
Signal quality measured values are ranked up by step 108 by presetting method；
Signal quality measured values can be ranked up by sequence from small to large or sequence from big to small, this hair
Bright embodiment is without specifically limiting.The present embodiment is by taking signal quality measured values are ranked up by sequence from small to large as an example
It is illustrated.
Reference table 6, table 6 show by
It is ranked up by sequence from small to large.
Table 6
It should be noted that if consider to exclude influence of the weak covering of network to voice quality, it can be by wireless signal strength
The corresponding data of the lower sampled point of measured value are deleted.
The signal quality measured values are divided into x signal quality section according to the second preset step-length by step 109；
Reference table 7, table 7, which is shown, is divided into x signal quality area according to the second preset step-length for signal quality measured values
Between after, signal quality section central value, signal quality sampling number corresponding to each signal quality section.Wherein, second is pre-
It is configured if the specific value of step-length can according to need, the embodiment of the present invention is without specifically limiting.The embodiment of the present invention
It is illustrated so that the second preset step-length is 1dB as an example, signal quality section central value is the letter of signal quality section central point
Number quality measured values, signal quality sampling number are the number for the signal quality measured values for including in each signal quality section.
Table 7
Step 110 obtains the corresponding MOS value for meeting preset speech service quality requirement in each signal quality section；
The specific value that preset speech service quality requires, which can according to need, to be configured, and the embodiment of the present invention is not
It is specifically limited, the present embodiment is said by taking the 10th percentage point of corresponding MOS value in each signal quality section as an example
It is bright.
Reference table 8, table 8 show MOS mean value and the 10th percentage point of corresponding MOS in each signal quality section
Value.
Table 8
Wherein, the corresponding MOS mean value of signal quality section i: MOSMean value (signal quality section i)=Average (signal quality section i
Corresponding all MOS values).The corresponding 10th percentage point of corresponding MOS value of signal quality section i:
MOS10th percentage point of (signal quality section i)=PERCENTILE (all MOS values corresponding to the i of signal quality section, 10%).
Step 111, by with the immediate MOS value institute for meeting preset speech service quality requirement of preset MOS threshold value
Corresponding signal quality Z is determined as the signal quality target value.
The specific value of preset MOS threshold value, which can according to need, to be configured, and the embodiment of the present invention is without specifically limiting
Fixed, the present embodiment is illustrated so that preset MOS threshold value is equal to 3.0 as an example.As can be drawn from Table 8, for each signal quality
MOS mean value in section is [- 13.5, -12.5], the signal matter with the immediate signal quality section of preset MOS threshold value
Measuring signal quality section central value corresponding to section is -13dB, can indicate that network coverage planning index is that signal quality is big
In equal to -13dB.The network coverage planning index indicates that voice quality MOS value is big when signal quality is more than or equal to -13dB
In 3.0 ratio be about 50%.It is and preset for the 10th percentage point of corresponding MOS value in each signal quality section
The immediate signal quality section of MOS threshold value is [- 0.5,0.5], in signal quality section corresponding to the signal quality section
Center value is 0dB, can indicate that network coverage planning index is that signal quality is more than or equal to 0dB.The network coverage planning index table
Show that, when signal quality is more than or equal to 0 dB, ratio of the voice quality MOS value greater than 3.0 is more than 90%.
If can be seen that from the analysis result of table 8 and determine network coverage planning index with MOS mean value, to guarantee
Mean value > 3.0 VoLTE voice quality MOS then only need signal quality to be more than or equal to -13dB, it can be seen that cover to wireless signal
Index request is very low, is to be difficult to meet the voice service of user to perceive if pressing this index planning network.
