1. A method in a Radio Access Network Congestion Awareness Function (RCAF), the method comprising:
retrieving an identity of a policy control unit of a mobile communication network, the policy control unit being associated with a plurality of mobile entities that are each connected to the mobile communication network via a corresponding radio access network, the retrieving comprising:
sending a request message via a Diameter Routing Agent (DRA) to the policy control unit, the request message comprising:
an identity of a given mobile entity of the plurality of mobile entities; and
congestion information only for the given mobile entity; and
receiving a response message including the identity of the policy control unit associated with the given mobile entity;
aggregating congestion information indicating congestion of the radio access network of at least some of the plurality of mobile entities based on the mobile entities being associated with the identified policy control unit; and
sending a message including the aggregated congestion information to the identified policy control unit, wherein said sending of the message employs the retrieved identity of the policy control unit to route the message.
