NETWORK DEVICE AND TERMINAL ABNORMALITY IDENTIFICATION METHOD THEREOF

摘要

The present invention provides a network device and a terminal abnormality identification method of the network device. The method comprises: obtaining wireless link transmission results, the wireless link transmission results comprising: hybrid automatic repeat request (HARQ) feedback results and/or cyclic redundancy check (CRC) results; obtaining first wireless link quality information and second wireless link quality information according to the wireless link transmission results, the first wireless link quality information and the second wireless link quality information being respectively the wireless link quality information when the wireless link state is a normal/abnormal state before the release of a wireless link; and when variations of the first wireless link quality information and the second wireless link quality information exceed set threshold values, identifying that a terminal is abnormal. According to the embodiment of the invention, the identification of terminal abnormality can be realized at a network side, and then, the accuracy of statistical network performance is improved.
