According to the embodiment, the signal leakage proportion of the target indoor substation is determined according to the ratio of the number of the leakage sampling points to the number of the target sampling points, and whether the signal of the target indoor substation leaks can be judged more reasonably based on the proportion and the preset proportion threshold.
Optionally, if it is determined that the signal of the target room substation leaks, a notification may be sent to the preset person, where the notification may indicate that the signal of the target room substation of the preset person leaks, so that the preset person can optimize the target room substation, and the network quality in the target building is improved.
According to the method for detecting the leakage of the indoor distribution signal, the target indoor distribution site related to the target building can be determined through the position of each indoor distribution site and the boundary of the target building, so that the first target MDT data and the target sampling point related to the target indoor distribution site can be accurately obtained according to the MDT data reported by the target indoor distribution site and the user terminal; according to the boundary of the target building and the first target MDT data, an external leakage sampling point can be accurately obtained; furthermore, according to the leakage sampling point and the target sampling point, whether the signal of the target room substation leaks can be judged without field detection by additional detection equipment, so that the cost is reduced, the operation is simple, the leakage detection efficiency is improved, the problems of high cost, complex operation and low efficiency of the existing detection method are solved, and theoretical support and solution ideas are provided for field investigation.
