Problems solved by technology

[0005] However, it is not timely and accurate to indicate whether the clock of the base station is out of synchronization through the loss of the clock reference source, which leads to a delay in the response of the base station, which directly affects the experience of network users.

Abstract

Embodiments of the present invention provide methods and devices for determining clock desynchronization. One method includes: based on the network measurement data sent by the base station, the network measurement data includes interference and noise (IN) information or power information, and detecting cells with abnormal IN information or power information in all cells of the entire network base station as the first Cell: Classify the first cell according to different types of abnormalities in IN information or power information to determine that one or more base stations in the entire network have clock desynchronization. The above technical solution detects cells with abnormal IN information (or power information) in the cells and classifies them according to different types of abnormal IN information (or power information) to determine that the base station clock is out of sync, so that relevant nodes can take timely measures to avoid clock synchronization. Out of sync affects the communication quality of the entire network.

Description

technical field [0001] The present invention relates to the field of wireless communication, and more particularly, to a method and a device for determining clock out-of-synchronization. Background technique [0002] The clock reference source is a necessary functional module of the TDD (English is Time Division Duplex, Chinese is Time Division Duplex) system, which is used for the cell synchronization of the base stations of the whole network to avoid the uplink and downlink cross-slot interference caused by the out-of-sync TDD system. The loss of the clock reference source can easily cause the clock of the TDD system to be out of sync, resulting in strong interference between the cell and the same-frequency cells of the base station adjacent to the base station to which the cell belongs, causing the terminal to fail to access the network, or the service is poor. For example, it is easy to cause call drop, handover failure, and inability to perform services, etc. The deteri...
