Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only used for explaining the present invention, not
For limiting the present invention.
Fig. 1 shows the detection method stream that in mobile communications network provided in an embodiment of the present invention, cell signal is dorsad revealed
Journey schematic diagram.According to as indicated with 1, this detection method comprises the steps:
Step s1: the control signaling data of collection cell base station sending and receiving stations；
Step s2: to described control signaling decoding data, and therefrom extract containing described cell and its each adjacent area
Measurement report data；
Step s3: count the dependency between each adjacent area and described cell；Dependency between adjacent area and cell is that this is little
The measurement report sample number containing this adjacent area that area's base transceiver station reports and the ratio of measurement report total sample number；
Step s4: judge that cell signal whether there is according to the dependency between each adjacent area and described cell and dorsad reveal.
In step s1, control signaling data is to be controlled from the base station of mobile operator communication network by bypassing collecting device
Collection in communication interface between device (bsc) and base transceiver station (bts).gsm、wcdma、td-scdma、cdma-1x、
Cdma-evdo has similar communication network architecture, and the present invention only gathers wireless network control signaling data.
In step s2, measurement report data contain this cell mobile terminal reporting give this cell base station sending and receiving stations with
The measurement report data of neighbor base station sending and receiving stations.Typically, cell is larger with the adjacent area dependency on its main lobe direction, with it
Adjacent area dependency on secondary lobe and episternites direction is less.By positioned at the adjacent area of cell base station sending and receiving stations main lobe direction and this cell
Dependency and secondary lobe and episternites direction on the ratio of the dependency of adjacent area and this cell can be seen that this cell base station is received and dispatched
The size of platform coverage direction deviation, or by with the dependency of each adjacent area and cell as weights, with each neighbor base station sending and receiving stations warp
Latitude is variable, calculates the virtual longitude and latitude after all neighbor base station sending and receiving stations weighted averages, then this cell base station is received and dispatched
The deflection of the vector to this virtual longitude and latitude for the platform longitude and latitude contrasts and can sentence with the deflection of the cell base station sending and receiving stations of planning
Break and the deviation of this cell base station sending and receiving stations deflection.
In step s3, when carrying out the correlation statistics of each adjacent area and this cell, timing statisticses can be carried out as needed
Setting.In the timing statisticses setting, extract, from the measurement report data extracted, the measurement report data comprising each adjacent area,
Often extract a measurement report data comprising adjacent area, then the measurement report sample number of this adjacent area is added 1, when this statistics
Between after, then it is total with measurement report sample to calculate the measurement report sample number containing this each adjacent area that this cell base station sending and receiving stations reports
The ratio of number, thus calculate the dependency between each adjacent area and this cell.
Following two judgment modes can be had to select in step s4.

The virtual direction angle of cell base station sending and receiving stations: cell base station sending and receiving stations longitude and latitude is to the virtual warp of neighbor base station sending and receiving stations
The deflection of the vector of latitude.
In mode two, the longitude and latitude of all adjacent areas is weighted averagely being equivalent to all adjacent areas are fused to a neighbour
Qu Zhong, that is, this cell only have this adjacent area, this adjacent area also only one of which base transceiver station, so, this cell base station sending and receiving stations
Geographical position to this neighbor base station sending and receiving stations geographical position just be this cell base station sending and receiving stations sense (main lobe side
To), its deflection is just the virtual direction angle of this cell base station sending and receiving stations.The virtual direction angle of cell base station sending and receiving stations is actually
Represent the sense that this cell base station sending and receiving stations reality is formed, by planning side with this cell base station sending and receiving stations by it
Can determine whether that this cell base station sending and receiving stations deflection whether there is deviation to angle contrast, deviation is more big more is possible to signal
Dorsad reveal.
After above method detects that signal has the cell dorsad revealed, signal can be will be deemed as have dorsad revealing
Cell with report form output or will be deemed as the actual coverage direction of signal and the signal that signal has the cell dorsad revealed
