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 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, determining, by the UE based on the first verification matching information, whether the UE capability information received by the MME is consistent with UE capability information sent by the UE to the MME, and, if the UE capability information received by the MME is consistent with the UE capability information sent by the UE to the MME, sending, by the UE, a NAS security mode complete message to the MME.

Abstract: A security protection method and an apparatus to implement security protection for a plurality of non-access stratum (NAS) connection links. The method includes determining, by a terminal, a first parameter, where the first parameter is used to indicate an access technology used to transmit a non-access stratum NAS message. The terminal can support at least two access technologies, and can separately maintain a corresponding NAS COUNT for each of the at least two access technologies. The method further includes performing, by the terminal, security protection on the NAS message based on the first parameter, a NAS key, and a NAS COUNT corresponding to an access technology used to transmit the NAS message.

Abstract: In a method for security handling in a mobility of a terminal device, a target access and mobility management function (AMF) entity receives a first message for registering a terminal device, sends a second message to a source AMF entity after receiving the first message. The source AMF entity derives a first key based on a key between the source AMF entity and the terminal device, sends the first key to the target AMF entity. The target AMF entity determines to use the first key based on security related information after receiving the first key and determines a communication key between the target AMF entity and the terminal device based on the first key after determining to use the first key.
