Problems solved by technology

[0005] The method provided by the prior art to transmit signals through the test terminal to observe the change of the RTWP of the cell to be tested and the adjacent cell, so as to detect whether the antenna feeder device of the cell to be tested is reversed. The test terminal must transmit signals at a fixed frequency and continuously at the maximum power, and it is difficult to find a test terminal that meets the requirements at the actual test site (such as the site construction site); in addition, testers must perform a comprehensive drive test on the network, and then Carrying out special analysis on drive test data RTWP is time-consuming and labor-intensive, with high economic costs and low work efficiency; and due to the method provided by the existing technology, errors are bound to exist due to manual detection, and some base station antenna feeder equipment may be reversed. Not detected, resulting in the coverage of the uplink being lower than the planned coverage or the relationship between adjacent cells is wrong, resulting in a decrease in the handover success rate
