Abstract: This application provides a proximity service communication method, a communication apparatus, and a communication system. When a terminal device requests a communication resource corresponding to a first sidelink, a management network element may determine, based on location information of the terminal device, whether the terminal device is located in a geographic area in which the terminal device can use a first application through a sidelink, to determine whether to provide a proximity service parameter for the terminal device. This limits, at an application granularity, sidelink communication used by the terminal device.

Abstract: This application discloses an abnormal offline state determining method and a related apparatus. The method includes: An access and mobility management function network element (AMF) obtains location information when an uncrewed aerial vehicle enters or leaves an offline state. If a location indicated by the location information is outside a target offline area, the AMF marks a state of the uncrewed aerial vehicle as an abnormal offline state. The AMF sends a state identifier of the abnormal offline state to an unmanned aircraft system traffic management network element (UTM). Therefore, the location information when the uncrewed aerial vehicle enters or leaves the offline state is used to determine whether the uncrewed aerial vehicle is in the abnormal offline state, so that accuracy of determining the abnormal offline state of the uncrewed aerial vehicle can be improved to some extent
