Interference detection method and device, interference elimination method, device and system

Abstract

An embodiment of the invention discloses a method for interference detection. The method for interference detection comprises the following steps that a first base station detects the intensity of an interference signal in a channel; and when the first base station determines that the intensity of the interference signal is greater than a first preset value, the first base station carries out spectral recognition on the interference signal and determines the frequency of the interference signal. An embodiment of the invention further discloses a method for interference elimination. The method for interference elimination comprises the following steps of receiving related information of the first base station and related information of a second base station which are reported by the base stations; determining reasons for cross timeslot interference and the base station causing the interference according to the received related information of the first base station and the related information of the second base station; and sending reconfiguration information to the base station causing the interference or reporting the interference alarm information. Embodiments of the invention further correspondingly disclose a device for interference detection, and a device and a system for interference elimination.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an interference detection method and device, an interference elimination method, device and system. Background technique [0002] On December 4, 2013, the Ministry of Industry and Information Technology officially issued 4G licenses. China Mobile, China Telecom, and China Unicom obtained 4G (TD-LTE) operating rights. -2690MHz) frequency bands have frequency allocation scenarios where multiple operators are adjacent to each other. The Ministry of Industry and Information Technology requires that the networks of multiple operators need to be synchronized and the proportion of uplink and downlink time slots coordinated. However, due to limitations in technology or competition strategies, it is very likely that base stations will lose synchronization and cause serious interference between base stations. [0003] At present, there is no effective measure to determine whe...

AI Technical Summary

Problems solved by technology

The Ministry of Industry and Information Technology requires that the networks of multiple operators need to be synchronized and coordinate the proportion of uplink and downlink time slots. However, due to limitations in technology or competition strategies, it is very likely that base stations will lose synchronization and cause serious interference between base stations.

[0003] At present, there are no effective measures to determine whether the base station is out of synchronization, nor can it locate the location of the interference of the out-of-synchronization base station, so that the corresponding repair work cannot be carried out
