Access control method, base station, user equipment, and mobility management entity

Abstract

The present invention provides an access control method, a base station, user equipment, and a mobility management entity, where the access control method includes: receiving, by the base station, a temporary identifier and a PLMN available indication that are of the UE and sent by the UE; receiving a service request message sent by the UE, and determining a serving MME of the UE according to a GMMEI in the temporary identifier of the UE; and sending the service request message and the PLMN available indication to the serving MME of the UE, so that the serving MME of the UE sends a redirection indication, and the UE registers with an HPLMN of the UE. Therefore, in a network sharing scenario, the UE can select the home PLMN of the UE as a serving PLMN of the UE as early as possible.
