A method and a device for positioning leakage of indoor distribution cells

Abstract

The embodiment of the invention provides an indoor distribution cell leakage positioning method and device. The method comprises the following steps of: according to the TA interval corresponding to the sampling point reported by each user in the indoor distribution cells in the sampling period; screening out a plurality of strong coverage neighbor cells according to the overlapping coverage sampling point proportion of each neighbor cell after the indoor distribution cell is known to be a leakage cell, and determining the leakage direction of the leakage cell according to the area commonly covered by each strong coverage neighbor cell and the station position of the leakage cell; And determining the leakage area of the leakage cell according to the distance and the leakage direction corresponding to the maximum leakage range of the leakage cell. The device is used for executing the method. According to the method and the device provided by the embodiment of the invention, the leakagearea of the leakage cell can be accurately positioned, and a clear direction is provided for leakage improvement, so that the influence of leakage on user perception is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of communications, and in particular to a method and device for locating leakage of an indoor subdivision cell. Background technique [0002] The indoor distribution system is a solution for improving the indoor mobile communication environment or increasing the indoor network capacity for indoor user groups; its principle is to use the indoor antenna distribution system to evenly distribute the signal of the mobile base station in the indoor corners, so as to ensure ideal signal coverage in indoor areas, allowing users to enjoy high-quality networks indoors. According to statistics, 70% of mobile terminal services are generated indoors. Therefore, the importance of indoor distribution systems is increasingly strengthened, and it is the object that needs to be guaranteed. [0003] According to traditional habits, the buildings or communities where the indoor distribution system is built are ...

Problems solved by technology

Therefore, it will be difficult for users to switch to the macro station after occupying the outdoor signal leakage of the indoor branch, which will have an impact on the user's service perception. Signal, the indoor branch has not added the adjacent area of ​​the macro station or has not cut out the adjacent area with the macro station, causing the user to occupy the low-level signal of the indoor branch all the time, and eventually go off the network, affecting user perception; the capacity of the indoor branch is limited, if the leaked area Too many users will affect the perception of indoor users; in the case of weak power level, the uplink transmission power of the terminal will increase, which will increase the overall noise floor of the site and affect the service perception of the whole site

[0004] Currently, there is no effective method for locating signal leaks in the indoor distribution system. The background KPI (Key Performance Indicator, Key Performance Indicator) cannot point to whether the site is leaked, nor can it accurately present the leaked area, which cannot meet the current network optimization work. requirements
