Abstract
The present disclosure is directed at systems, methods and media for mitigating congestion for roamers in a wireless access network. In some embodiments, Radio Access Network (RAN) congestion information is reported from a base station to a RAN Congestion Awareness Function (RCAF) of a visited network. The RCAF can mitigate congestion by controlling Quality of Service (QoS) parameters for roaming User Equipment (UE) in a congested cell. The RCAF can further communicate with the Mobility Management Entity (MME) of the visited cell and the Policy Charging and Rules Function (PCRF) of the UE's home network. The RCAF can relieve congestion for roamers without informing the home network of the congestion at the cell.
