[0006] For 4G (4th-generation, fourth-generation mobile communication technology) LTE (Long Term Evolution, long-term evolution) mobile communication systems, currently weak coverage areas are mainly found through the combination of customer complaints and active testing. Among them, active testing Only roads and specific optimized areas can be covered, and active testing will consume more material and manpower; while relying on customer complaints to find weak coverage cells, there will be a problem of discovery lag, which will affect user experience
To sum up, for the 4G LTE system, there is no relatively mature positioning scheme for weak coverage areas

Embodiment 1
[0263] Embodiment 1: locating weaker 4G coverage areas based on 4G MR data. Such as Figure 13 As shown, this embodiment includes the following steps:
[0264] Step 501: Extract 4G MR data, extract the MR data of the whole network for one week according to the requirements of China Mobile OMC-R specification, it is recommended to enable the reporting of AoA and TA. The original data format is as follows:
[0265]
[0266]
[0267] Step 502: Merge MR data. Merge the MR data with the same Report Time and userlabel into one, that is, one sample point for subsequent processing, as shown in the table below.
[0268]
[0269] Step 503: Select an accurate geolocation solution according to the extracted MR data.
[0270] For each MR sample point merged through the preceding steps, the data integrity is different, and the positioning scheme is different. The data scTA and scAOA required for the positioning scheme based on TA+AoA are listed as MR array A (denoted as MR Arr...
Embodiment 2
[0333] Embodiment 2: The MR data of 2G or 3G is used to locate the extremely weak or no coverage area of 4G. Such as Figure 14 As shown, this embodiment includes the following steps:
[0334] Step 601: 2G or 3G MR data extraction. According to the requirements of China Mobile OMC-R specification, extract the MR data of 2G or 3G network for one week. For 3G MR, it is recommended to enable reporting of AoA and TA.
[0335] Step 602: Merge and filter MR data. Merge the data with the same reporting time and UE number into one piece, that is, one sample point, and only keep the sample points containing the level information of 4G neighboring cells.
[0336] Step 603: Select an accurate geolocation solution according to the reserved MR sample points.
[0337] For 3G MR: similarly, classify scTA and scAOA into MR Data Group A, and use a positioning scheme based on TA+AoA; classify scPccpchRSCP and ncPccpchRSCP of at least two non-common basestation neighbor cells into MR Dat...

Abstract
The invention provides a positioning method and a positioning device for the weak coverage area and belongs to a wireless communication system. The positioning method for the weak coverage area comprises an acquiring step for acquiring a measurement report for a plurality of user equipment within a preset period of time, wherein the measurement report is a report for measuring the user equipment in a 4G and / or 2G and / or 3G system; a positioning step for determining the coordinates of the plurality of user equipment according to the acquired measurement report; a judging step for dividing the coverage area into a plurality of grids of a preset size, respectively judging whether each of the plurality of grids is a weak coverage grid or not according to a preset weak coverage grid judgment condition, and determining the weak coverage area according to judgment results. According to the weak coverage grid judgment condition, for all user equipment within a grid, the ratio of the user equipment with the RSRP thereof smaller than a preset threshold to all the user equipment in the grid is greater than or equal to a preset proportion. According to the technical scheme of the invention, the weak coverage area in the 4G system can be found out.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a positioning method and device for a weak coverage area. Background technique [0002] For 3G (3rd-generation, third-generation mobile communication technology) mobile communication systems, there already exist some methods for locating weak coverage areas based on measurement report (Measurement Report, MR) data. Wherein, the MR data include: field strength, signalangle of arrival (Angle of Arrival, AOA), time advance (Time Advance, TA) and so on. In the 3G system, the field strength refers to RSCP (Received Signal Code Power, received signal code power). [0003] In the 3G system, there are mainly the following ways to locate weak coverage areas based on MR data: [0004] The first is the location method based on field strength. By detecting the field strength value of the received signal, the distance between the transceivers can be estimated by using the known chann...
