Fuente: Wipo "IOT" The present disclosure relates to the technical field of communications, and provides ambient Internet of things-based communication methods, a terminal, a network device and a communication system. A method comprises: an A-IOT terminal acquiring first information and, according to the first information, acquiring query scheduling information; and, according to the query scheduling information, determining that the A-IOT terminal performs communication transmission. When the technical solution of the present disclosure is used, configuring different query scheduling information can embody scheduling of A-IOT terminals of different priorities, so as to determine whether the A-IOT terminals perform communication transmission and the opportunities of the A-IOT terminal for communication transmission, thereby embodying the scheduling priorities of the different A-IoT terminals, and allowing the A-IOT terminals of higher priorities to have an advantage in scheduling.
