Access control method and device, and computer-readable medium

An Access Control (AC) method, applied to a terminal and comprising:

• transmitting an AC parameter request to a network-side device;
• receiving a first AC parameter returned by the network-side device in response to the AC parameter request, wherein the first AC parameter has a correspondence with a network slice;
• and
• performing AC for the network slice corresponding to the first AC parameter based on the first AC parameter.

A terminal device, comprising a second network interface, a second memory and a second processor, wherein

• the second network interface is configured to receive and transmit a signal in a process of receiving and transmitting information with another external network element;
• the second memory is configured to store a computer program capable of running in the second processor;
• and
• the second processor is configured to run the computer program to:
• control the second network interface to transmit an AC parameter request to a network-side device;
• control the second network interface to receive a first AC parameter returned by the network-side device in response to the AC parameter request, wherein the first AC parameter has a correspondence with a network slice;
• and
• perform AC for the network slice corresponding to the first AC parameter based on the first AC parameter.

An Access Control (AC) method, applied to a terminal and comprising:

• transmitting an AC parameter request to a network-side device;
• receiving a third AC parameter returned by the network-side device in response to the AC parameter request, wherein the third AC parameter has a correspondence with a Public Land Mobile Network (PLMN);
• and
• performing AC for the PLMN corresponding to the third AC parameter based on the third AC parameter.
