Method and system for RAN-based traffic flow control

A radio access network (RAN) device of a RAN comprising:

• a communication interface;
• a memory, wherein the memory stores instructions;
• and
• a processor, wherein the processor executes the instructions to:
• store first coverage information for a communication link established between the RAN device and an end device, wherein the first coverage information includes one or multiple first attributes of the communication link, and wherein the RAN device is a next generation Node B (gNB) or an evolved Node B (eNB);
• receive, via the communication interface from the end device after the storing, a request to establish a packet data unit (PDU) session via the communication link;
• receive, via the communication interface, a profile that includes multiple instances of second coverage information, wherein each instance of second coverage information correlates to one or multiple traffic flow control parameters and values;
• compare, in response to a receipt of the profile, the multiple instances of the second coverage information to the first coverage information;
• select, in response to the comparison, one of the multiple instances of the second coverage information that matches the first coverage information;
• and
• enforce, subsequent to an establishment of the PDU session, the one or multiple traffic flow control parameters and values, which correlate to the selected one of the multiple instances of the second coverage information, in relation to a traffic flow of the communication link.

A non-transitory computer-readable storage medium storing instructions executable by a processor of a radio access network (RAN) device that is a next generation Node B (gNB) or an evolved Node B (eNB) of a RAN, which when executed cause the RAN device to:

• store first coverage information for a communication link established between the RAN device and an end device, wherein the first coverage information includes one or multiple first attributes of the communication link;
• receive from the end device after the storing, a request to establish a packet data unit (PDU) session via the communication link;
• receive a profile that includes multiple instances of second coverage information, wherein each instance of second coverage information correlates to one or multiple traffic flow control parameters and values;
• compare, in response to a receipt of the profile, the multiple instances of the second coverage information to the first coverage information;
• select, in response to the comparison, one of the multiple instances of the second coverage information that matches the first coverage information;
• and
• enforce, subsequent to an establishment of the PDU session, the one or multiple traffic flow control parameters and values, which correlate to the selected one of the multiple instances of the second coverage information, in relation to a traffic flow of the communication link.
