Embodiment Construction

[0068] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0069] Before introducing the specific execution process of this application, first introduce the possible interference types of TD-LTE:

[0070] This application involves that the TD-LTE network is a same-frequency network and the network structure is becoming more and more complex. When multiple networks operate at the same time, they will be subject to multiple interferences from inside and outside the network. According to the frequency range of the TD-LTE network, the main sour...

Abstract

The invention provides a method and a device for determining the interference type. The method comprises the steps of acquiring target PRB data of a high-interference cell within a preset time period; matching the target PRB data with multiple groups of PRB feature information one by one, wherein each group of PRB feature information corresponds to one interference type; and determining the interference type corresponding to the group of PRB feature information which is successfully matched with the target PRB data to be the interference type of the high-interference cell. According to the invention, the uplink interference type of a TD-LTE base station can be analyzed and determined automatically, so that the type of interference suffered by the TD-LTE base station can be confirmed accurately and efficiently.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for determining an interference type. Background technique [0002] For mobile communication networks, the prerequisite for ensuring service quality is to use clean spectrum, that is, the frequency band is not used or interfered by other systems. Otherwise, it will have a relatively large negative impact on the disturbed system performance and the experience of end users. [0003] With the gradual construction of 4G TD-LTE base stations, the coexistence of 2G, 3G and 4G base stations has formed, and the probability of interference between systems has also increased significantly. Among the currently constructed base stations, a large number of TD-LTE base stations have been found to be interfered. These interferences mainly include blocking interference, intermodulation interference and spurious interference from 2G and 3G cells to TD-...
