Abstract: Embodiments of the present disclosure provide a service optimization processing method, a device, and a system. Sensor information of UE is reported to a network device, the network device predicts a status of the UE based on the sensor information of the UE, and optimizes a service of the UE based on the status, or the network device performs service adjustment based on the sensor information of the UE. In this way, power consumption of the UE can be effectively reduced, and user experience is improved. In addition, network signaling and resource usage can be optimized, and channel resource utilization is improved.
