A method comprising: receiving, by a RAN Congestion Awareness Function, RCAF, load information for a plurality of cells (104a-b) of a Radio Access Network, RAN,, wherein the load information comprises an identity for each cell of the plurality of cells (104a-b) and a corresponding congestion level for each cell of the plurality of cells (104a-b); determining, by the RCAF, for each of a plurality of user equipment, UE, (102a-c) in each cell, identification information for each UE (102a-c) and an Access Point Name, APN, to which each UE is connected; sending, by the RCAF to a Diameter Routing Agent, DRA, an Attribute Value Pair, AVP, wherein the AVP comprises: a particular identity for a particular cell, a particular congestion level of the particular cell, a first list indicating each APN to which each UE in the particular cell is connected, and a second list indicating each of the plurality of UE (102a-c) in the particular cell; identifying, from a plurality of policy servers (122.1-N), each policy server that serves each APN to which each UE in each cell of the plurality of cells (104a-b) is connected; and sending, to each of a particular policy server (122.1), congestion information comprising: an identity for each of one or more cells (104a-b) having UE (102a-g) that are connected to each of one or more APN served by the particular policy server (122.1), the corresponding congestion level for each of the one or more cells (104a-b), and a per-cell UE list identifying each of a plurality of UE (102a-g) connected to each of the one or more APN served by the particular policy server (122.1). receiving, by a RAN Congestion Awareness Function, RCAF, load information for a plurality of cells (104a-b) of a Radio Access Network, RAN,, wherein the load information comprises an identity for each cell of the plurality of cells (104a-b) and a corresponding congestion level for each cell of the plurality of cells (104a-b); determining, by the RCAF, for each of a plurality of user equipment, UE, (102a-c) in each cell, identification information for each UE (102a-c) and an Access Point Name, APN, to which each UE is connected; sending, by the RCAF to a Diameter Routing Agent, DRA, an Attribute Value Pair, AVP, wherein the AVP comprises: a particular identity for a particular cell, a particular congestion level of the particular cell, a first list indicating each APN to which each UE in the particular cell is connected, and a second list indicating each of the plurality of UE (102a-c) in the particular cell; a particular identity for a particular cell, a particular congestion level of the particular cell, a first list indicating each APN to which each UE in the particular cell is connected, and a second list indicating each of the plurality of UE (102a-c) in the particular cell; identifying, from a plurality of policy servers (122.1-N), each policy server that serves each APN to which each UE in each cell of the plurality of cells (104a-b) is connected; and sending, to each of a particular policy server (122.1), congestion information comprising: an identity for each of one or more cells (104a-b) having UE (102a-g) that are connected to each of one or more APN served by the particular policy server (122.1), the corresponding congestion level for each of the one or more cells (104a-b), and a per-cell UE list identifying each of a plurality of UE (102a-g) connected to each of the one or more APN served by the particular policy server (122.1). an identity for each of one or more cells (104a-b) having UE (102a-g) that are connected to each of one or more APN served by the particular policy server (122.1), the corresponding congestion level for each of the one or more cells (104a-b), and a per-cell UE list identifying each of a plurality of UE (102a-g) connected to each of the one or more APN served by the particular policy server (122.1).
