Assuming that include that n cell (is only for example, the quantity of n is according to actual small in mobile network in mobile network hereinArea's quantity determines), such as the range of overlay area is marked using the UE location information of MDT measurement file acquisition, specific method canTo get grid division ready using backstage latitude and longitude information.The network quality parameters of this n cell are respectively G1, G2 ... ...Gi ... ..., Gn；For the network quality parameters Gi of i-th of cell, the RSRP (Reference in cell is depended primarily onSignal Receiving Power, Reference Signal Received Power), RSRQ (Reference Signal ReceivingQuality, Reference Signal Received Quality) and/or SINR (Signal to Interference plus Noise Ratio, letterNumber with interference plus noise ratio) etc. parameters.For example, by using RSRP as network quality parameters.
For RSRP: it is the key parameter that wireless signal strength (or network quality) is represented in network, which gets overLow, corresponding network quality is poorer, and RSRP value corresponds to corresponding coverage strength grade and covering parameter, such as:
RSRP≤- 105, coverage strength class 6, representative covering is poor, and business can not rise substantially and exhale；
- 105 < RSRP≤- 95, covering grade 5, representative covering is poor, and outdoor service can rise and exhale, but success rate is low, fallWords rate is high, and indoor business can not rise substantially and exhale；
- 95 < RSRP≤- 85 covering grades 4, indoor and outdoors energy outdoor service, which can rise, exhales, but success rate is low,The high outdoor service of cutting off rate, which can rise, exhales, but success rate is low, and cutting off rate is high；

For example, Gi is less than G for the cell of priority support type, then the network for adjusting the corresponding base station of the cell coversLid parameter, the adjustment for the network coverage parameter, single adjust 2% that amplitude is not higher than the second preset threshold, if adjustedGi after whole is greater than or equal to G, then adjusts completion, if Gi adjusted is less than G, continues the corresponding base station of the cellNetwork coverage parameter adjustment, equally, single adjust amplitude be not higher than the second preset threshold 2%, until adjustment complete.
Mode two, for the cell of non-priority support type in the weak coverage cell, if non-in the weak coverage cellThe cell of priority support type and the cell of one or more priority support types in each cell are non-conterminous, with describedThe network coverage of the corresponding base station of cell of non-priority support type in the weak coverage cell is adjusted on the basis of two preset thresholdsParameter, so that the network quality parameters of the cell of non-priority support type are greater than or equal to described first in the weak coverage cellPreset threshold.
For example, Gi is less than G for the cell of non-priority support type, then the network of the corresponding base station of the cell is adjustedParameter, the adjustment for the network coverage parameter are covered, single adjusts 2% that amplitude is not higher than the second preset threshold, ifGi adjusted is greater than or equal to G, then adjusts completion, if Gi adjusted is less than G, continues the corresponding base of the cellThe adjustment for the network coverage parameter stood, equally, single adjust 2% that amplitude is not higher than the second preset threshold, until adjustment is completed.
Alternatively, after executing step S103, for the cell of non-priority support type in the weak coverage cell, if instituteState the small of the cell of non-priority support type and one or more priority support types in each cell in weak coverage cellArea is adjacent, reports abnormal instruction to OMC (Operation and Maintenance Center, operation and maintenance center).

After executing step 3, step 4 or step 5 are continued to execute；
Step 4, the guarantee type based on the weak coverage cell adjusts the network of the weak associated base station in coverage cellParameter is covered to enhance the network coverage quality of the weak coverage cell.
Specifically, for the cell of priority support type in the weak coverage cell, Gi is less than G, then adjusts the cellThe network coverage parameter of corresponding base station, the adjustment for the network coverage parameter, it is pre- not higher than second that single adjusts amplitudeIf the 2% of threshold value, judge whether Gi adjusted is less than G, if it is not, then adjustment is completed, if it is, continuing the cellThe adjustment of the network coverage parameter of corresponding base station, equally, single adjust 2% that amplitude is not higher than the second preset threshold, untilAdjustment is completed.
For the cell of non-priority support type, Gi is less than G, then adjusts the network coverage ginseng of the corresponding base station of the cellNumber, the adjustment for the network coverage parameter, single adjust 2% that amplitude is not higher than the second preset threshold, if after adjustmentGi whether be less than G, if it is not, then adjustment complete, if it is, continue the corresponding base station of the cell the network coverage ginsengSeveral adjustment, equally, single adjust 2% that amplitude is not higher than the second preset threshold, until adjustment is completed.
Step 5, for the cell of non-priority support type in the weak coverage cell, if non-heavy in the weak coverage cellPoint ensures that the cell of type is adjacent with the cell of one or more priority support types in each cell, to OMC(Operation and Maintenance Center, operation and maintenance center) reports abnormal instruction.
