1. A method comprising:
obtaining, by a processing system including a processor, information from a network element of a communication network, the communication network including a plurality of cells each associated with one or more user equipment devices (UEs), the information comprising mapping data for each of the plurality of cells respectively and the UEs associated therewith, wherein the network element is in communication with the processing system via the communication network;
generating, by the processing system, a historical record of cell load data, wherein the cell load data represents traffic in the plurality of cells, the traffic including content distributed to the plurality of cells from the processing system;
determining, by the processing system, that a cell of the plurality of cells is congested, based on the historical record;
identifying, by the processing system, the one or more UEs associated with a congested cell, based on the information;
selecting, by the processing system, a shaping level from a plurality of shaping level tiers for each UE of the one or more UEs, wherein each UE of the one or more UEs is assigned to one of the plurality of shaping level tiers; and
performing, by the processing system for each of the one or more UEs associated with the congested cell, a congestion shaping (CS) procedure, the CS procedure including the shaping level selected for the UE of the one or more UEs for adjusting content flow associated with that UE.
