Abstract

The invention provides a ZigBee terminal device re-online method and a ZigBee terminal device. The method comprises the following steps: when the ZigBee terminal equipment fails to be online again, entering first sleep; when the ZigBee terminal equipment finishes the first sleep, determining a re-online strategy according to a re-online attempt result of the ZigBee terminal equipment before entering the first sleep, wherein when the re-online attempt result indicates that the potential father node exists, the re-online strategy is to request to access the potential father node indicated by there-online attempt result.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a ZigBee terminal device re-online method and ZigBee terminal device. Background technique [0002] After the ZigBee terminal device is offline, it will restore the connection with the parent node by going online again. Once the re-online fails, the radio frequency (RF) module of the ZigBee terminal device will go to sleep. After the sleep is over, the ZigBee terminal device actively scans all channels to find potential parent nodes, so as to try to get online again. Scanning all channels is very power-intensive, so for battery-powered ZigBee end devices, how to save power is an important consideration. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a ZigBee terminal device re-online method and ZigBee terminal device, which can determine the current re-online attempt strategy according to the result of the last re-onlin...
