Problems solved by technology

[0006] The hazards of reverse connection of antenna and feeder lines are manifested as: the actual coverage area of ​​the two cells connected reversely is reversed from the planned range, resulting in more handover failures and poor call quality.
[0007] At present, the problem of reverse connection of antenna and feeder lines is mainly solved by on-site troubleshooting, which requires testers to conduct a comprehensive manual test on the network, which is inconvenient to operate and low in work efficiency.

Abstract

The invention discloses an antenna feeder reversal detection method based on road test data. The method comprises the following steps S1, importing road test data and importing a base station database; S2, traversing all sampling points of the road test data, and determining the quantity of base stations; S3, judging the quantity of cells covered by the same base station, analyzing the antenna feeder reversal of a cell to be tested; S4, judging whether an antenna feeder is reversed or not; S5, finding all base stations in which the antenna feeders are reversed, and outputting. Through analysis of the road test data and base station database information, areas where antenna feeders are reversed are positioned rapidly, thereby increasing efficiency and saving the cost.

Description

technical field [0001] The invention relates to the field of communication network optimization, in particular to a method for detecting reverse connection of antenna and feeder lines based on drive test data. Background technique [0002] The antenna feeder is the radio frequency transmission line connecting the antenna and the transmitter or receiver. An antenna feeder and two feeders form an antenna feeder system to form a one-receive-one-transmit working mode. Antenna feeder system is one of the important components of microwave relay communication. The antenna plays the role of converting electromagnetic waves transmitted in the feeder into electromagnetic waves propagated in free space, or converting electromagnetic waves propagated in free space into electromagnetic waves transmitted in the feeder. The feeder is the transmission channel of electromagnetic waves. In the microwave relay communication circuit of the multi-channel shared antenna and feeder system, the t...
