Access control method and device
An access control method, including 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 radio resource control (RRC) establishment request message to an access layer of the terminal, where the request message carries an indication of not performing an ACB check.
1. An access control method, comprising:
obtaining, by a terminal, an override identifier;
determining, by the terminal, that the override identifier is overriding an access class barring (ACB) check after a service initiated by the terminal passes an application specific congestion control for data connectivity (ACDC) check; and
establishing, by the terminal, a radio resource control (RRC) connection in response to the terminal determining that the identifier is overriding the ACB check.
2. The method according to claim 1 , wherein the obtaining the override identifier comprises:
receiving, by the terminal, a system broadcast message from a wireless access network device, wherein the system broadcast message comprises the override identifier.
3. The method according to claim 2 , wherein the system broadcast message further comprises a service list corresponding to the override identifier.
4. The method according to claim 2 , wherein the terminal is in an idle state when the system broadcast message is received.
5. The method according to claim 1 , wherein the establishing the RRC connection in response to the terminal determining that the identifier is overriding the ACB check comprises establishing the RRC connection while omitting the ACB check.
6. An apparatus, comprising:
at least one processor; and
a computer-readable storage medium storing a program to be executed by the least one processor, the program including instructions for:
obtaining an override identifier;
determining the override identifier is overriding an access class barring (ACB) check after a service passes an application specific congestion control for data connectivity (ACDC) check; and
establishing a radio resource control (RRC) connection in response to the determining the override identifier is overriding the ACB check.
7. The apparatus according to claim 6 , wherein the instructions for obtaining the override identifier include instructions for:
receiving a system broadcast message from a wireless access network device, wherein the system broadcast message comprises the override identifier.
8. The apparatus according to claim 7 , wherein the system broadcast message further comprises a service list corresponding to the override identifier.
9. The apparatus according to claim 7 , wherein the apparatus is in an idle state when the system broadcast message is received.
10. The apparatus according to claim 6 , wherein the instructions for establishing the RRC connection in response to the apparatus determining that the identifier is overriding the ACB check include instructions for establishing the RRC connection while omitting the ACB check.
11. A non-transitory computer-readable storage medium storing a program to be executed by at least one processor, the program including instructions for:
obtaining an override identifier;
determining the override identifier is overriding an access class barring (ACB) check after a service passes an application specific congestion control for data connectivity (ACDC) check; and
establishing a radio resource control (RRC) connection in response to the determining the override identifier is overriding the ACB check.
12. The non-transitory computer-readable storage medium according to claim 11 , wherein the instructions for obtaining the override identifier include instructions for:
obtaining a system broadcast message, wherein the system broadcast message comprises the override identifier.
13. The non-transitory computer-readable storage medium according to claim 12 , wherein the system broadcast message further comprises a service list corresponding to the override identifier.
14. The non-transitory computer-readable storage medium according to claim 12 , wherein the instructions for obtaining the system broadcast message include instructions for obtaining the system broadcast message while an apparatus executing the program is in an idle state.
15. The non-transitory computer-readable storage medium according to claim 11 , wherein the instructions for establishing the RRC connection in response to determining that the identifier is overriding the ACB check include instructions for establishing the RRC connection while omitting the ACB check.
