The invention discloses a method and a system for identifying the blocking condition of a base station antenna. The method for identifying the blocking situation of the base station antenna comprisesthe following steps: acquiring a plurality of sampling points of different reference signal receiving power intervals in a near point area of the base station antenna from LTE-MR data measured for a base station cell; determining the ratio of each sampling point to the sum of the plurality of sampling points according to the plurality of sampling points, and determining a first variance of the ratio of the plurality of sampling points; selecting a sampling point subset from the plurality of sampling points according to the first variance, and determining a second variance of reference signal receiving power corresponding each sampling point in the sampling point subset; and comparing the second variance with a threshold to determine whether the base station antenna is blocked or not.
Description
technical field [0001] The present invention relates to the technical field of communications, and more particularly relates to a method and system for identifying blocking conditions of base station antennas. Background technique [0002] Base station antennas are an important part of wireless communication systems. The base station antenna may be blocked by other objects due to various reasons, resulting in rapid attenuation of base station receiving / sending signals, which seriously affects the coverage and service quality of the mobile communication network. [0003] Traditionally, in order to determine the blocking situation of the base station antenna, the staff needs to conduct a site traversal survey to determine whether the base station antenna is blocked by naked eyes, or based on road test (DT) data or indoor traversal test (CQT), by close observation of the signal Strength or manual analysis of the signal characteristics in the test records to preliminarily judge...
