Method and system for identifying coverage black hole of wireless cell

Abstract

A method for identifying a coverage black hole of a wireless cell comprises the following steps: acquiring control plane data and user plane data in a detection area through a probe deployed between an access network and a core network; according to the collected control plane data and user plane data, identifying the wireless cell covered with the black hole in the detection area and the positioninformation of the covered black hole in the wireless cell. According to the method disclosed in the invention, the coverage black hole problem of the wireless cell can be discovered in time, the position of the coverage black hole is positioned, and therefore the operation and maintenance cost of the wireless network is greatly reduced.

Description

technical field [0001] The embodiments of the present application relate to but are not limited to the field of communication technology, especially a method and system for identifying coverage black holes in wireless cells. Background technique [0002] With the rapid development of modern communication technology, users have higher and higher requirements for network quality, and communication coverage requirements are becoming more and more extreme. In addition to urban and indoor coverage, barren mountains and wild forests also need coverage. In the current communication systems of major operators, the annual maintenance cost and labor cost of the wireless communication network are very high. [0003] In a traditional manner, a measurement report (MR, Measurement Report) is used to determine the coverage problem of a cell. However, the MR method has a large amount of data and the data collection time is limited, resulting in poor real-time judgment results; secondly, th...

However, the MR method has a large amount of data and the data collection time is limited, resulting in poor real-time judgment results; secondly, the MR method mainly judges based on network signal-related indicators, and good network signal-related indicators do not mean that users perceive it as good ;In addition, the wireless equipment of the operator generally comes from multiple manufacturers, and the whole network monitoring through MR needs to use a multi-vendor system, and it is difficult to achieve the whole network monitoring by requiring all manufacturers to report data according to the same interface standard; , it is basically impossible to report MR data when there is no signal, resulting in the inability to judge the coverage of the cell
