Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a method for determining uplink and downlink coverage balance of VOLTE according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
and 140, obtaining a judgment result according to the uplink and downlink sampling point proportion data and a first judgment rule, and realizing VOLTE uplink and downlink coverage balance judgment according to the judgment result.
Firstly, respectively carrying out interval division on RSRP and a Physical Uplink Shared Channel (PUSCH) according to 1dB, then counting MOS mean values of all intervals, carrying out trend analysis through a two-bit line graph, and taking an inflection point level of an Uplink PUSCH with the MOS being more than or equal to 3.0 as a first Uplink sensing inflection point level threshold; taking the inflection point level of CRS RSRP with MOS more than or equal to 3.0 as a first downlink sensing inflection point level threshold, wherein the described uplink PUSCH level is the PUSCH level transmitted on a single Physical Resource Block (PRB) of the user terminal received by the base station side, and the described uplink PUSCH level can be equivalent to the PUSCH level of the PUSCH transmitted power on the single PRB of the user terminal reaching the base station after the path loss same as the downlink direction.
After the correction, a second uplink and downlink sensing inflection point level threshold can be obtained, and the second uplink and downlink sensing inflection point level threshold can be suitable for the dense networking environment, so that the limitation caused by a small-range area test result is overcome.
The embodiment of the invention can obtain uplink and downlink low level ratio difference data through uplink and downlink sampling point ratio data, and the first judgment rule in the embodiment of the invention is to judge the VOLTE uplink and downlink coverage condition according to the interval judgment of the uplink and downlink low level ratio difference data. The interval judgment here may mean that if the difference data of the upper and lower low level ratios is more than or equal to 5.00%, the VOLTE uplink and downlink coverage balance of the target cell is judged at this time; if the difference data of the upper and lower low level ratio is more than or equal to 25.00%, judging that the VOLTE uplink coverage of the target cell is weak; and if the difference data of the upper and lower low level accounts for less than or equal to 5.00 percent, judging that the VOLTE downlink coverage of the target cell is weak.
For example, we select a certain base station to lock the D frequency band for small-range region testing, and test VOLTE MOS pull network services when CRS =6\, 12\, 18\, 21, respectively. And exploring the uplink and downlink sensing inflection point level thresholds under the pure wireless environment scene through the rule among the MOS level, the RSRP level and the PUSCH level.
The level threshold condition of sensing inflection points of uplink and downlink services of VOLTE in a small-range area test is as follows:
where "-" represents that no significant inflection point was found in the statistics.
When the MOS is more than or equal to 3.0 in field test, the downlink limited RSRP is = -121dBm, and the uplink limited PUSCH is = -121dBm; and when the MOS is more than or equal to 3.5, the downlink limited RSRP is = 109dBm, and the uplink limited PUSCH is = 117dBm. And changing the base station from downlink coverage limitation to uplink coverage limitation along with the increase of the CRS. When CRS =6, as RSRP decreases, MOS gradually decreases, and uplink PUSCH is not associated with MOS change, which indicates that uplink is not limited at this time. The MOS also gradually decreases as RSRP or PUSCH decreases when CRS = 21. However, the RSRP threshold at this time is lower than the RSRP threshold at CRS =6, which indicates that the downlink coverage level range is shrunk due to uplink coverage limitation at this time.
And then correcting the uplink and downlink sensing inflection point level thresholds in the small-range area test, wherein the corrected VOLTE uplink and downlink service sensing inflection point level thresholds are as follows:
where "-" represents that no significant inflection point was found in the statistics.
And determining the proportion data of the uplink sampling points and the downlink sampling points according to the corrected uplink sensing inflection point level threshold and the corrected downlink sensing inflection point level threshold, and finally realizing VOLTE uplink and downlink coverage balance judgment according to a first judgment rule.
The embodiment of the invention obtains the sensing inflection point level threshold of the uplink and downlink services of the VOLTE through a small-range test; then, correcting the uplink and downlink service sensing inflection point level threshold to obtain a second uplink and downlink sensing inflection point level threshold which can be applied to a dense networking scene, determining uplink and downlink sampling point proportion data according to the second uplink and downlink sensing inflection point level threshold, and further obtaining uplink and downlink sampling point proportion difference data; therefore, the uplink and downlink coverage balance is judged by judging the interval of the uplink and downlink sampling point ratio difference data, but in the embodiment of the invention, the subsequent steps can be carried out only by acquiring the uplink and downlink sensing inflection point level threshold through the prior art, and the whole process does not need to newly add a data statistical module, thereby improving the judgment efficiency.
On the basis of the foregoing embodiment, the first uplink and downlink sensing inflection point level threshold and the second uplink and downlink sensing inflection point level threshold are specifically:
the first uplink and downlink sensing inflection point level threshold comprises a first uplink sensing inflection point level threshold and a first downlink sensing inflection point level threshold;
the second uplink and downlink sensing inflection point level threshold comprises a second uplink sensing inflection point level threshold and a second downlink sensing inflection point level threshold.
Specifically, the first uplink and downlink sensing inflection point level thresholds described in the embodiments of the present invention are the first uplink sensing inflection point level threshold and the first downlink sensing inflection point level threshold; the second uplink and downlink sensing inflection point level threshold described in the embodiment of the invention is the second uplink sensing inflection point level threshold and the second downlink sensing inflection point level threshold.
The first uplink sensing inflection point level threshold, the first downlink sensing inflection point level threshold, the second uplink sensing inflection point level threshold and the second downlink sensing inflection point level threshold described in the embodiment of the invention are beneficial to the subsequent steps.
On the basis of the foregoing embodiment, the step of performing correction processing on the first uplink and downlink sensing inflection point level threshold to obtain a second uplink and downlink sensing inflection point level threshold specifically includes:
according to the grid pull-up standard, correcting the first uplink sensing inflection point level threshold by increasing noise margin to obtain a second uplink sensing inflection point level threshold;
according to the grid pull-in standard, correcting the first downlink sensing inflection point level threshold through the signal to interference plus noise ratio to obtain a second downlink sensing inflection point level threshold
And obtaining a second uplink and downlink sensing inflection point level threshold according to the second uplink sensing inflection point level threshold and the second downlink sensing inflection point level threshold.
Specifically, the grid pull standard described in the embodiments of the present invention refers to a general standard in grid testing, and the general standard belongs to a grid testing standard known to those skilled in the art. Compared with the situation of a small-range test, the impact of the dense networking scenario on the downlink service mainly lies in the situation that the SINR deteriorates when a plurality of base station areas overlap, and the impact factor on the uplink service mainly lies in the rise of the IOT.
Therefore, the IOT margin can be increased according to the IOT standard in the grid pull-up standard, so as to correct the first uplink perceptual knee level, for example, when a small-range area is tested, the IOT of a single test site is-117 dBm, and the IOT standard of an uplink high-interference cell in the grid pull-up standard is IOT ≧ 110dBm, then it is recommended to increase the IOT margin to 7dBm.
Meanwhile, the first uplink sensing inflection point level threshold can be corrected through an SINR value, specifically, the first uplink sensing inflection point level threshold and RSRP data in a grid pull network standard respectively corresponding to the same SINR value are used, so that the first uplink sensing inflection point level threshold is adjusted to RSRP data; for example, in the small-range area test, when the RSRP of a single test site in the downlink is-121 dBm, SINR =0, and at this time, the RSRP data in the corresponding grid pull standard is-111 dBm, then the downlink RSRP should be corrected from-121 dBm to-111 dBm.
The embodiment of the invention corrects the first uplink sensing inflection point level threshold by the SINR value; correcting the first downlink sensing inflection point level threshold by increasing noise margin; therefore, the problem that the first uplink and downlink sensing inflection point level threshold possibly caused by the small-range area test is not suitable for the dense networking scene can be solved after the correction, and the subsequent steps can be conveniently carried out.
On the basis of the above embodiment, the step of obtaining the uplink and downlink sampling point ratio data according to the second uplink and downlink sensing inflection point level threshold specifically includes:
acquiring uplink total sampling point data and downlink total sampling point data;
obtaining uplink sampling point proportion data according to the second uplink sensing inflection point level threshold and the uplink total sampling point data;
obtaining downlink sampling point ratio data according to the second downlink sensing inflection point level threshold and the downlink total sampling point data;
and obtaining the uplink and downlink sampling point ratio data according to the uplink sampling point ratio data and the downlink sampling point ratio data.
Specifically, the uplink total sampling point data in the embodiment of the present invention includes the total number of the uplink total sampling points and the PUSCH value of each sampling point; the downlink total sampling point data comprises the total number of the downlink total sampling points and the MR RSRP value of each sampling point.
The described obtaining of the uplink total sampling point data may be obtained according to an Operation and Maintenance Center (OMC), the downlink total sampling point data may be obtained according to a Measurement Report (MR) platform, and the proportion of the number of sampling points, of which the PUSCH value is smaller than the second uplink sensing inflection point level threshold, in the uplink total sampling point data to the total number of the uplink sampling points is determined as uplink sampling point proportion data; and judging the proportion of the number of sampling points with the RSRP value smaller than the second downlink sensing inflection point level threshold to the total number of the downlink sampling points in the downlink total sampling point data to be used as downlink sampling point proportion data.
The uplink total sampling point data and the downlink total sampling point data described in the embodiment of the invention can be counted through the existing platform, no additional module is needed for counting, the original data is more convenient to obtain, and the uplink sampling point proportion data and the downlink sampling point proportion data obtained in the embodiment are both beneficial to the subsequent steps.
On the basis of the above embodiment, the step of obtaining a determination result according to the uplink and downlink sampling point proportion data and the first determination rule to achieve balance determination of uplink and downlink coverage of VOLTE according to the determination result specifically includes:
obtaining uplink and downlink low level ratio difference data according to the uplink and downlink sampling point ratio data;
and obtaining a judgment result according to the first judgment rule and the uplink and downlink low level ratio difference data.
Specifically, the described uplink and downlink low level ratio difference data is difference data between uplink sampling point ratio data and downlink sampling point ratio data; the first judgment rule described in the embodiment of the present invention specifically judges a judgment result corresponding to the uplink and downlink low level occupancy difference data by judging which preset interval the uplink and downlink low level occupancy difference data belongs to, where the judgment result includes multiple situations of uplink and downlink coverage balance, weak uplink coverage, weak downlink coverage, and the like, and we can make a VOLTE uplink and downlink coverage balance judgment according to the judgment result.
According to the embodiment of the invention, after the uplink and downlink level ratio difference data are obtained, the uplink and downlink coverage balance of the VOLTE can be judged according to the preset interval to which the ratio difference data belong.
On the basis of the foregoing embodiment, the step of obtaining the determination result according to the first determination rule and the uplink and downlink low-level ratio difference data specifically includes:
if the difference data of the up-down low level ratio is in a first preset interval, obtaining the judgment result as up-down coverage balance;
if the uplink and downlink low level ratio difference data is in a second preset interval, obtaining the judgment result that the uplink coverage is weak;
and if the uplink and downlink low level ratio difference data is in a third preset interval, obtaining the judgment result that the downlink coverage is weak.
Specifically, the preset interval described in the embodiment of the present invention may be obtained by determining a distribution of an uplink and downlink low level ratio difference interval of a high-quality cell, where the high-quality cell described herein is a cell that satisfies a certain condition, and specifically, the following table shows:
| parameter name | Index threshold |
| LTE radio access rate [ unit:%] | ≥99.50％ |
| VOLTE radio call-through rate [ unit:%] | ≥99.50％ |
| LTE radio drop rate [ unit:%] | ≤0.50％ |
| VOLTE voice drop rate [ unit:%] | ≤0.50％ |
| LTE handover success rate [ unit:%] | ≥99.00％ |
| VOLTE user handover success rate:%] | ≥99.00％ |
| Average IOT [ unit: dBm ]] | ≤-110dBm |
| LTE RRC connection reestablishment ratio:%] | ≤5.00％ |
The analysis of the difference value of the low level occupancy of the uplink and the downlink of the high-quality cell shows that the interval of the difference value of the low level occupancy of the uplink and the downlink of the high-quality cell is in normal distribution, the interval of the difference value of the low level occupancy of the uplink and the downlink is 10 percent, the peak value occurs, and the difference value of 90 percent of the high-quality cell before and after the peak value is between 5 percent and 25 percent, so the interval of the difference value of the low level occupancy of the uplink and the downlink is 5 percent to 25 percent is divided into a first preset interval; dividing an interval with the difference value of the low level ratio of the uplink and the downlink larger than 25% into a second preset interval; and dividing the interval of which the ratio difference of the upper low level and the lower low level is less than 5% into a third preset interval. And subsequently, different CRS values are set, so that the difference value of the ratio of the uplink low level to the downlink low level of most of high-quality cells is still distributed between 5.00% and 25.00%.
According to the embodiment of the invention, the preset interval is set according to the distribution condition of the uplink and downlink low level ratio difference value interval of the high-quality cell, after the preset interval is set, the judgment of the VOLTE uplink and downlink coverage balance can be completed according to which preset interval the uplink low level ratio difference value of the target cell belongs to, the data acquired by the existing module is used in the whole process, and the judgment of the VOLTE uplink coverage balance can be realized without additionally building a platform or adding a module.
On the basis of the above embodiment, the method further comprises:
if the uplink sampling point proportion data is in a fourth preset interval, judging that the target cell is an uplink weak coverage cell;
and if the downlink sampling point proportion data is in a fifth preset interval, judging that the target cell is a downlink weak coverage cell.
Specifically, the PUSCH low-level ratio statistics is performed on the high-quality cells, and if 95.00% of the high-quality cell ratio data is distributed within 35.00%, the fourth preset interval is set to have the uplink sampling point ratio data within 35.00% -100.00%; therefore, the target cell with the uplink sampling ratio data of more than 35.00% is defined as the uplink weak coverage cell. Performing MR RSRP low-level ratio statistics on the high-quality cells, and finding that 95.00% of the high-quality cells are distributed within 10.00%, the fifth preset interval sets the downlink sampling point ratio data as the downlink sampling point ratio data within 10.00% -100.00%.
The embodiment of the invention can complete the setting of the preset interval through the uplink and downlink low-level ratio distribution condition of the high-quality cell, thereby judging whether the target cell is an uplink and downlink weak coverage cell according to whether the uplink and downlink sampling point ratio data of the target cell belongs to the preset interval or not.
