摘要： Embodiments of the present application provide methods for checking UE capability match, an AMF, a base station, and a storage medium. The method includes: determining to send a UE capability match request to a base station during a registration procedure initiated by the UE; sending a request for setting up a UE's access stratum (AS) security context to the base station, and sending the UE capability match request to the base station after it is determined that the base station completes setup of the AS security context; receiving a UE capability match acknowledgement returned from the base station. By the method according to the embodiment of the application, the problem that the base station does not respond to the UE capability match process requested by the AMF, which results in that the AMF cannot issue an indication of IMS voice over PS session to the UE during the registration process, can be avoided, and thus the UE can normally obtain IMS voice service.
