Method and device for judging cause of communication interruption, wireless node and working method

Abstract

The embodiment of the invention provides a method for judging the cause of communication interruption, which is used for wireless node networking, the wireless node networking comprises an uplink interface and a plurality of wireless nodes, each wireless node has wireless communication capability and is in communication connection with the uplink interface through a network cable, and the uplink interface is connected with the plurality of wireless nodes. The method comprises the following steps: determining at least one offline wireless node which is interrupted in communication with an uplink interface; if confirmation information sent by other wireless nodes except the offline wireless node through a network cable is received within the threshold time, judging that a communication interruption reason is that the network cable cannot work; sending the confirmation information after other wireless nodes except the offline wireless node receive error reporting signals from the offline wireless node in a wireless mode; and if the confirmation information is not received within the threshold time, judging that the reason of communication interruption is that the offline wireless node cannot work. The embodiment of the invention also provides a communication interruption reason judgment device, a wireless node and a working method.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of communication, and in particular to a method and device for judging a cause of communication interruption, a wireless node and a working method. Background technique [0002] With the development of wireless access point networking, the number of wireless APs (Access Points, wireless access points) is increasing, and communication interruption of wireless access points is a common fault phenomenon. When the communication of the wireless access node is interrupted, if it is impossible to know whether the cause of the communication interruption is the failure of the network cable or the failure of the wireless access node, the maintenance personnel will not be able to distinguish the communication failure, and the maintenance efficiency of the wireless access node network will be reduced. Contents of the invention [0003] Embodiments of the present disclosure provide a method a...
