Problems solved by technology

[0008] (1) When checking interference, some TD-LTE sites need to be shut down, which will affect user access and network capacity;
[0009] (2) It is necessary to go to the antenna for testing, and the work efficiency is not high, and some antenna installation locations are not convenient for high-altitude operations;
[0010] (3) Part of the interference occurs irregularly, and there is a possibility of omission even on the site for investigation;
[0011] (4) There are a large number of base stations and they are widely distributed. Checking one by one, the efficiency is low and the feasibility is not high

Embodiment Construction

[0051] In the embodiment of the present invention, the base station (eNB) measures the interference-to-noise ratio (IOT) in real time, identifies the source of the interference signal according to the measured IOT, and sends the measured IOT and the obtained source of the interference signal to the operation and maintenance center (OMC); The OMC receives the measured IOT and the obtained source of the interference signal sent by the eNB, and determines the type of the interference signal according to the received IOT and the source of the interference signal.

[0052] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] Embodiments of the present invention implement a base station for automatic interference detection, such as Figure 4 As shown, the base station (eNB) includes a measurement module 1, an identification module 2 and a sending module 3; wherein,

Abstract

The present invention provides a method for the automatic detection of interference, which comprises: an eNB (evolved Node B) measures an IOT (Interference over Thermal noise) in real time, identifies the source of an interference signal according to the measured IOT, and sends the measured IOT and the obtained source of the interference signal to an OMC (Operation and Maintenance Center); and the OMC receives the measured IOT and the obtained source of the interference signal sent by the eNB, and determines the type of the interference signal according to the received IOT and the source of the interference signal. The present invention also provides equipment and system for the automatic detection of the interference.

Description

technical field [0001] The invention relates to an interference checking technology of a communication system, in particular to a device, system and method for automatic interference detection. Background technique [0002] At present, most of the following methods are used to check the interference of TD-LTE: [0003] (1) Deactivate the TD-LTE cell to be tested and the TD-LTE cell within 1-2 circles around, try to eliminate the influence of TD-LTE signal on the interference signal; [0004] (2) At the TD-LTE antenna, connect the spectrum analyzer to the antenna port of the TD-LTE cell, observe the frequency domain signal, detect the frequency band and amplitude of the interference signal, and detect the time domain characteristics of the TD-LTE frequency point, Determine which radio access technology the interference comes from; [0005] (3) According to the engineering parameters of TD-LTE wireless access technology, determine the possible source of interference; [000...
