Abstract: The present invention discloses a flight area management method for an uncrewed aerial vehicle and a related apparatus. The method includes: An access and mobility management function AMF obtains flight area exception information of an uncrewed aerial vehicle, where the flight area exception information indicates that the uncrewed aerial vehicle is not located in a normal flight area. The AMF sends a flight area exception notification message to an uncrewed aerial system traffic management UTM, where the flight area exception notification message is used to indicate that the uncrewed aerial vehicle is not located in the normal flight area. When flight area exception occurs on the uncrewed aerial vehicle, using the UTM to control the uncrewed aerial vehicle can improve controlling safety for the uncrewed aerial vehicle.

Abstract: The present invention provides a cell selection method and apparatus. The cell selection method includes: sending, by a non-access stratum of user equipment UE, network list information to an access stratum of the UE, where the network list information includes a list of forbidden networks and a list of forbidden networks for a GPRS service; determining, by the non-access stratum, indication information about a cell selection priority according to an operation mode of the UE; and sending, by the non-access stratum, the indication information to the access stratum, so that the access stratum selects a suitable cell according to the network list information and the indication information. The present invention can effectively prevent the UE from entering a state of being able to normally camp but unable to obtain a normal service, thereby improving user experience.

Abstract: An access method and an apparatus are provided. After access of the terminal to the dedicated core network that is corresponding to the DCN indication information and that the terminal needs to access is rejected by the first PLMN, the terminal re-determines the second PLMN different from the first PLMN, so as to connect, by using the second PLMN, the terminal and the dedicated core network corresponding to the DCN indication information, so that the terminal can quickly access the dedicated core network. In this way, system resource utilization and user experience are improved.

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.
