Access control method, communications device, and base station

An access control method, comprising:

• configuring, by a communications apparatus, a first unified access control (UAC) parameter for user equipment (UE) based on a first coverage enhancement level (CE-level);
• after the UE accesses the communications apparatus based on a second CE-level, receiving, by the communications apparatus, information that is about the first CE-level and that is sent by the UE, wherein the second CE-level is higher than the first CE-level;
• and
• performing, by the communications apparatus, signaling transmission based on the first CE-level.

A communications apparatus, comprising a processor, wherein the processor is coupled to a memory, and reads and executes instructions that are stored in the memory, to implement:

• determining, based on a first coverage enhancement level (CE-level), a first unified access control (UAC) parameter corresponding to the first CE-level;
• determining, based on the first UAC parameter, whether access of the communications apparatus is barred;
• and
• when the communications apparatus determines, based on the first UAC parameter, that the access is barred, determine, based on a second UAC parameter corresponding to a second CE-level, whether the access is barred, wherein the second CE-level is higher than the first CE-level.
