By the aid of the group-based anonymous switching authentication method, the problem of congestion conditions due to the fact that large quantities of machine-type devices are switched over in existing standards mainly can be solved. The group-based anonymous switching authentication method includes procedures of enabling a current base station or current MME (mobile management entity) to transmit secure session information of all switched group members to a target base station or MME when first machine-type devices in machine-type communication device switched groups are about to be switched to the target base station from the current base station; allowing switching authentication procedures to be carried out between other machine-type devices in the switched groups and the target base station without MME contact, allowing the other machine-type devices to negotiate with the target base station eNB to obtain session keys so as to implement quick switching authentication of the devices in the groups. The group-based anonymous switching authentication method has the advantages that the signaling overhead can be greatly reduced under the condition that the privacy of users is guaranteed, and signaling conflict can be prevented.
