Method and system for application-based access control using network slicing

A network device comprising:

• a communication interface;
• and
• a processor, wherein the processor is configured to:
• determine a congestion level pertaining to one or more resources of the network device of a radio access network;
• generate, based on the congestion level, access barring information that includes a first threshold network slice priority value that indicates a threshold slice priority that is to be satisfied by network slice priority values assigned to network slices and correlated first applications or portions of the correlated first applications of one or more end devices so as to be granted access to and not barred from the network device;
• and
• transmit, via the communication interface, the access barring information to the one or more of the end devices.

A non-transitory computer-readable storage medium storing instructions executable by a processor of a network device, which when executed cause the network device to:

• determine a congestion level pertaining to one or more resources of the network device of a radio access network;
• generate, based on the congestion level, access barring information that includes a first threshold network slice priority value that indicates a threshold slice priority that is to be satisfied by network slice priority values assigned to network slices and correlated first applications and portions of the correlated first applications of one or more end devices so as to be granted access to and not barred from the network device;
• and
• transmit the access barring information to the one or more of the end devices.
