A BEACON DEVICE AND A BEACON STATE INDICATING METHOD AND SYSTEM

摘要

A beacon device and a beacon state indicating method and system are provided. The system includes some beacon devices, which are classified as the Primary Protection Device (PPD) and the Secondary Protection Device (SPD). The SPD indicates whether the next super-frame needs to send the beacon state sequentially in the transmitting beacon message. The PPD determines the rights of transmitting beacon message of at least one beacon device in the next super-frame based on the beacon state. It is able to be realized that sequentially transmitting the beacon message in the next super-frame when an entire beacon message of a beacon device is not transmitted at all by this invention. The delay of fully transmitting the beacon message is avoided.
