Access Control Method and Device

摘要

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, 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, even if the terminal cannot pass the ACB check, the terminal can still perform services of some particular applications.

1. An access control method, comprising:
storing, by an access layer of a terminal, an override identifier sent by a wireless access network device; sending, by the access layer of the terminal, an application specific congestion control for data connectivity (ACDC) check starting notification; receiving, by the access layer of the terminal and after a service initiated by the terminal passes an ACDC check, a radio resource control (RRC) establishment request; establishing an RRC connection in response to the access layer of the terminal determining that a stored coverage identifier is overriding an access class barring (ACB) check; and starting the ACB check in response to the access layer of the terminal determining that the stored coverage identifier is not overriding the ACB check, and establishing the RRC connection after the ACB check is passed.
