An access control method includes: obtaining, by a protocol-stack upper layer of a terminal, an override identifier; starting, by the protocol-stack upper layer of the terminal, an application specific congestion control for data connectivity ACDC check according to a service initiated by the terminal; and according to the override identifier sent by a core network and received by the protocol-stack upper layer of the terminal, if the protocol-stack upper layer of the terminal confirms that the service initiated by the terminal can pass the ACDC check and determines that the override identifier corresponding to an application identifier of the service passing the ACDC check is overriding an access class barring ACB check, sending, by the protocol-stack upper layer of the terminal, an RRC establishment request message to an access layer of the terminal, where the request message carries an indication of not performing an ACB check; therefore, the ACB check does not need to be performed. Therefore, in some special cases, even if the terminal cannot pass the ACB check, the terminal can still perform services of some particular applications (for example, a disaster information bulletin board service). |
