Abstract

The embodiment of the invention discloses an indoor distributed signal leakage check method and an indoor distributed signal leakage check device. The method comprises the following steps of: obtaining terminal measurement reports (MRs) from a base station, analyzing the MRs and obtaining MR data; filtering invalid MRs; generating neighbor cell pairs according to the MR data obtained after filtration, wherein each neighbor cell pair comprises information measured by a terminal main serving cell and information measured by an indoor distributed cell, the main serving cell is an outdoor macrocell and the indoor distributed cell is a neighbor cell of the outdoor macrocell; and finally judging whether signal leakage exists in the indoor distributed cell or not according to the information recorded by the neighbor cell pairs, computing the direction of the signal leakage of the indoor distributed cell to simply and accurately know the cell in which indoor distributed signal leakage exists in advance, and making an adjustment to prevent influence on outdoor subscribers.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for checking indoor signal leakage. Background technique [0002] With the continuous increase of the number of mobile users, the communication quality of users inside buildings has attracted more and more attention. Indoor distribution systems are increasingly providing coverage for office buildings, subways, residential areas, shopping malls and other scenarios, ensuring the call quality of users in these areas. [0003] If the indoor distribution system is not constructed properly, indoor users will not get good call quality, and outdoor users will also be adversely affected by the indoor distribution system. Among them, the signal leakage of the indoor division cell is the most influential factor on the outdoor terminal. [0004] The indoor sub-cell refers to the cell of the base station serving the indoor distributed system. The room inc...
