Base station location precision be 50 meters, however, it is determined that base station position and record base station position deviation at 100 meters or more, then recognize
For the location information inaccuracy of the base station of record.(2) for rural area base station, base station location precision is 200 meters, however, it is determined that base
The deviation of the position of the base station of the position and record stood is at 500 meters or more, then it is assumed that the location information of the base station of record is inaccurate
Really.
If it is determined that base station antenna azimuth and record base station antenna azimuth deviation be more than predetermined angle, then
Think the antenna azimuth inaccuracy of the base station of record.
In addition, base station basic information biggish for deviation, the base station basic information that aforementioned determination can be used updates note
The base station basic information of record, alternatively, can be with field survey, and the base station of the base station basic information more new record with field survey
Basic information.
By analyzing drive test data, the basic such as position and antenna directional angle of base station can be timely and accurately determined
Data improve the quality and efficiency of wireless network maintenance and management.
