Access control method and device, computer readable medium and system

A user equipment (UE), comprising:

• a first network interface, a first memory, and a first processor;
• wherein,
• the first network interface is configured to receive and send signals during a process of transceiving information with another external network elements;
• the first memory is configured to store a computer program capable of running on the first processor;
• and
• the first processor, when running the computer program, is configured to:
• generate a first cause value through a radio resource control (RRC) layer;
• encapsulate the first cause value in an RRC dedicated signaling;
• and
• send the RRC dedicated signaling and encapsulated with the first cause value to a network side device, wherein the RRC dedicated signaling is used by the network side device for access control.

A non-transitory computer-readable medium storing a program for access control, the program for access control, when executed by at least one processor, implements:

• generating a first cause value through a radio resource control (RRC) layer;
• encapsulating the first cause value in an RRC dedicated signaling;
• and
• sending the RRC dedicated signaling and encapsulated with the first cause value to a network side device, wherein the RRC dedicated signaling is used by the network side device for access control.
