Method and device for determining clock out-of-synchronization

Abstract

Embodiments of the present invention provide a method and an apparatus for determining clock desynchronization. The method includes: detecting a cell with exceptional IN information or power information among all cells of base stations throughout a network according to network measurement data sent by a base station, and using the cell as a first cell, where the network measurement data includes interference and noise (IN) information or power information; and sorting the first cell according to different types of exceptions of the IN information or power information, so as to determine that one or more of the base stations throughout the network are in clock desynchronization. With the above technical solution, cells with exceptional IN information (or power information) are detected among all cells, and are sorted according to different types of exceptions of the IN information (or power information) to determine the the clock desynchronization of the base station, and the relevant node can take timely actions to prevent the clock desynchronization from affecting communication quality throughout the 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...

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.
