Wireless network access control method and apparatus

A wireless network access control method, wherein the method comprises:

• receiving, by a terminal device, an access control parameter from a radio access network device, wherein the access control parameter comprises an identifier of one or more network slices;
• determining, by the terminal device, to access one or more network slices;
• and
• sending, by the terminal device, a random access request or an radio resource control (RRC) connection request, wherein the random access request or the RRC connection request comprises an identifier of the one or more network slices.

A radio access network device, comprising:

• a receiving module, configured to receive a random access request message or an radio resource control (RRC) connection request message that are sent by a terminal device, and receive an overload control indication message, an overload control termination indication message, or an access control adjustment indication message that are sent by a core network device, wherein the message comprises an identifier of one or more network slices;
• the processor is configured to:
• a processing module, configured to set an access control parameter of the one or more network slices, wherein the access control parameter comprises the identifier of the one or more network slices;
• collect statistics about resource usage of the one or more network slices in the radio access network device;
• and
• adjust or restore the access control parameter based on an indication that is sent by the core network device and that is received by the communication interface and/or a statistical result obtained by the radio access network device;
• and
• a sending module, configured to send the access control parameter to the terminal device.

A radio access network device, comprising a processor and a communication interface, wherein:

• the communication interface is configured to:
• receive a random access request message or an radio resource control (RRC) connection request message that are sent by a terminal device, and
• receive an overload control indication message, an overload control termination indication message, or an access control adjustment indication message that are sent by a core network device, wherein the message comprises an identifier of one or more network slices;
• the processor is configured to:
• set an access control parameter of the one or more network slices, wherein the access control parameter comprises the identifier of the one or more network slices;
• collect statistics about resource usage of one or more network slices in the radio access network device;
• and
• adjust or restore the access control parameter based on an indication that is sent by the core network device and that is received by the communication interface and/or a statistical result obtained by the radio access network device;
• and
• the communication interface is further configured to:
• send the access control parameter to the terminal device.

A terminal device, comprising a processor and a communication interface, wherein:

• the processor is configured to receive, via the communication interface, an access control parameter that is sent by a radio access network device, wherein the access control parameter comprises an identifier of one or more network slices;
• the processor is further configured to determine to access one or more network slices;
• and
• the processor is further configured to send, via the communication interface, a random access request message or an RRC connection request message, wherein the random access request message or the RRC connection request message comprises the identifier of the one or more network slices.
