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

Abstract: This application provides a communication method and a terminal apparatus. The communication method includes: A terminal apparatus receives a trigger message, where the trigger message includes a notification information identifier. When the terminal apparatus does not store notification information corresponding to the notification information identifier, the terminal apparatus ignores the trigger message. In this method, when receiving a useless trigger message, the terminal apparatus does not perform processing, thereby reducing power consumption.

Abstract: The mobility management network element performs security protection on a paging identity of a terminal device by using a security context obtained by negotiating with the terminal device, to obtain a first paging identity, and sends a first paging message to a base station. The base station sends a second paging message to the terminal device, where the second paging message carries the first paging identity and first indication information, and the first indication information is used to indicate that the first paging identity is a security-protected paging identity. The terminal device performs security verification on the first paging identity by using the security context based on the first indication information, to obtain a second paging identity, and processing the second paging message based on the second paging identity and an identity of the terminal device.

Abstract: The present disclosure relates to mobile communications technologies, and in particular, to a mobile communication method, apparatus, and device. The method includes receiving, by a user equipment UE, a non-access stratum NAS security mode command message from a mobility management entity MME, where the NAS security mode command message carries first verification matching information used to verify UE capability information received by the MME. Based on the first verification matching information, the UE determines whether the UE capability information received by the MME is consistent with UE capability information sent by the UE to the MME. In response to determining that the UE capability information received by the MME is consistent with the UE capability information sent by the UE to the MME, the UE sends a NAS security mode complete message to the MME.
