Description
Technical Field
The present invention relates to the field of mobile communication technologies, and in particular, to a coverage evaluation method and apparatus for an LTE network.
Background
At present, the main measures for LTE network coverage assessment are divided into two categories, one is an LTE network coverage assessment method based on DT (Drive Test)/CQT (Call Quality Test), and the other is an LTE network coverage assessment method based on MR (Measurement Report) positioning.
1. LTE network coverage evaluation method based on DT/CQT
DT is a method of measuring the performance of a wireless network using test equipment moving along a specified route, allowing different types of calls to be made, recording test data, and accounting for network test metrics.
CQT also refers to testing wireless data network performance at a fixed location. For example, spot testing of government agencies, large hotels, schools, hospitals, large venues or malls, etc.
2. LTE network coverage evaluation method based on MR positioning
The MR data does not contain position information, network coverage is evaluated by using MR, and the key technology is to position the position of the user equipment. At present, the MR positioning method is mainly based on signal field intensity positioning, the signal field intensity positioning method can estimate the distance between the transmitter and the transmitter by detecting the field intensity value of the received signal and using the known channel fading model and the field intensity value of the transmitted signal to obtain a plurality of distance values, and can determine the position of the target mobile station by solving the distance equation set between the transmitter and the transmitter. A field strength measurement constrains the mobile station (i.e., the positioning target) to a circle of trajectory around the base station, the radius of the circle being determined by the field strength value and the channel fading model. Since the two circle intersections are usually two, the target position must generally be determined by three base stations.
In particular, fig. 1 is a schematic illustration of MR localization. As shown in FIG. 1, point A, B, C, 3 is the known anchor point and has the coordinates of (x) respectivelya,ya)，(xb,yb)，(xc,yc) If the measured RSSI (Received Signal Strength Indicator) values from the anchor node A, B, C to the point D to be measured are obtained, the distances from the point D to the point A, B, C can be obtained according to the propagation path loss model of the radio signalsa、rb、rcFrom the geometric relationship, one can derive:
(xa-xd)2+(ya-yd)2＝ra 2(1)
(xb-xd)2+(yb-yd)2＝rb 2(2)
(xc-xd)2+(yc-yd)2＝rc 2(3)
the coordinates of the node to be measured can be obtained by the formulas (1), (2) and (3).
For the LTE network coverage assessment method based on DT/CQT, as DT test can only test roads through which vehicles can pass, CQT test can only test public areas such as corridors of a small part of office buildings and residential houses, for example, roads in small roads and cells can not be subjected to DT test, and indoor non-public areas such as offices of the party and government, residential houses and the like can not be subjected to test mostly. Therefore, the DT/CQT test can only reflect the network coverage from local points or lines, and cannot reflect the network coverage from the surface in a comprehensive way.
For the LTE network coverage evaluation method based on MR positioning, in an actual environment, since a wireless communication signal is affected by a mobile wireless channel, signal propagation may be reflected, diffracted or scattered, resulting in attenuation of a propagation signal, and thus an error may be generated by ranging through an RSSI value, so that three circles in fig. 1 do not intersect at one point, and an actual situation is shown in fig. 2. Although the coordinate information of the D point can still be obtained by the geometric operation processing as in the case shown in fig. 2, the error is relatively large. The inventor of the application finds that the average error value of MR positioning is 150-200 m, and because the average inter-station distance of the existing urban LTE base station is only about 300 m, and the error of MR positioning reaches half of the inter-station distance and is close to the actual coverage radius of a cell, the error of the LTE network coverage evaluation method based on MR positioning is extremely large, and the planning and optimization work of an LTE network cannot be effectively guided.

Specifically, the XDR data is obtained from an S1-U interface of the LTE network, and a data line including latitude and longitude information is extracted from a uniform resource identifier uri (uniform resource identifier) field corresponding to the XDR data. Then, information separation and filtration are carried out on the data line, the current position of the user equipment is obtained, and the current position of the user equipment is marked on the map. Therefore, compared with the LTE network coverage evaluation method based on MR positioning, the accuracy is greatly improved, and the average error is reduced from 150-200 meters to about 30-50 meters.

The basic information includes time, ID of a base station communicatively connected to the user equipment, and information such as MME (Mobile management Entity) -UE-S1AP (protocol) -ID. The reference signal received power is one of the key parameters that can represent the radio signal strength in LTE networks and the physical layer measurement requirements, and is the average of the received signal power over all REs (resource elements) that carry reference signals within a certain symbol.
Then, in step S105, the first XDR data and the second XDR data are associated according to the basic information of each user equipment, so as to obtain the reference signal received power of each user equipment at the current location.
Finally, in step S106, coverage information of the LTE network is evaluated according to the reference signal received power of each ue at the current location on a map.
