Access control method, terminal device, and radio access network device

An access control method, comprising:

• sending, by a radio access network device, access control information to a terminal device, wherein the access control information comprises a plurality of check items arranged in a predetermined order, and each of the plurality of check items comprises target object information and result processing information, wherein:
• the plurality of check items are used by the terminal device to check the plurality of check items in the predetermined order when the terminal device needs to initiate access or a service, the target object information is used by the terminal device to check whether the terminal device belongs to a target object indicated by the target object information, and the result processing information is used to indicate that a successful check is used as a final result or an unsuccessful check is used as a final result;
• and
• when the terminal device belongs to a target object indicated by target object information comprised in a current check item, a check result of the current check item and result processing information of the current check item are used by the terminal to determine the check result of the current check item as the final result or to check a next check item obtained in the predetermined order from the plurality of check items.

A terminal device, comprising:

• a processor, a memory, a receiver, and a transmitter coupled via a bus system;
• and
• wherein the memory is configured to store one or more instructions which, when executed by the processor, cause the terminal device to:
• receive access control information sent by a radio access network device, wherein the access control information comprises a plurality of check items arranged in a predetermined order, each of the plurality of check items comprises target object information and result processing information, and the result processing information indicates that a successful check is used as a final result or an unsuccessful check is used as a final result,
• when the terminal device needs to initiate access or a service, check a first check item obtained in the predetermined order from the plurality of check items,
• obtain, when the terminal device belongs to a target object indicated by first target object information comprised in the first check item, a first check result based on the first check item, wherein the first check result is a successful check or an unsuccessful check, and
• when the first check item is not a last check item of the plurality of check items, determine the first check result as the final result based on the first check result and first result processing information of the first check item, or check a second check item obtained in the predetermined order from the plurality of check items.
