Mobile communication method, apparatus, and device

A mobile communications apparatus, wherein the apparatus is deployed in a user equipment (UE) and comprises:

• a receiver, configured to receive a non-access stratum (NAS) security mode command message from a mobility management entity (MME), wherein the NAS security mode command message carries first verification matching information used to verify UE capability information received by the MME;
• at least one processor, configured to determine, based on the first verification matching information, the UE capability information received by the MME is consistent with UE capability information sent by the UE to the MME;
• and
• a transmitter, configured to send a NAS security mode complete message 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.

A user equipment (UE), comprising:

• at least one processor;
• and
• a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, the programming instructions instruct the at least one processor to:
• receive a non-access stratum (NAS) security mode command message from a mobility management entity (MME), wherein the NAS security mode command message carries first verification matching information used to verify UE capability information received by the MME;
• and
• 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 based on the first verification matching information, send, by the UE, a NAS security mode complete message to the MME.
