Abstract: A method is provided in one example embodiment and may include receiving load information for a plurality of cells of a Radio Access Network (RAN); determining, for each of a plurality of user equipment (UE) in each cell, identification information for each UE and an Access Point Name (APN) to which each UE is connected; identifying, from a plurality of policy servers, each policy server that serves each APN to which each UE in each cell of the plurality of cells is connected; and sending, to each of a particular policy server, congestion information comprising: an identity for each cell having UE that are connected to each APN served by the particular policy server; the corresponding congestion level for each of the cells; and a per-cell UE list identifying each of a plurality of UE connected to each of APNs served by the particular policy server.

Abstract: A method is provided in one example embodiment and may include receiving congestion information for an environment in which a user equipment (UE) is operating; receiving a first request to deliver content to the UE; determining that the environment in which the UE is operating is experiencing congestion based, at least in part, on the congestion information; determining a re-try interval based, at least in part, on the congestion information; and deferring delivery of the content to the UE until the re-try interval has expired. In one example embodiment, the method can include provisioning one or more policy rules for a service data flow associated with the content and communicating the indication indicating that delivery of the content has been deferred to a charging system to set charging information for at least one of a user associated with the UE or a provider of the content.

Abstract: A method is provided in one example embodiment and may include maintaining, by a Diameter Routing Agent (DRA), an availability status for a plurality of network elements; receiving a request associated with a user equipment (UE) session, wherein a first network element of the plurality of network elements is serving the UE session; determining that the first network element serving the UE session is unavailable; and re-establishing the UE session at a second network element of the plurality of network elements that is available, wherein the re-establishing is performed without terminating the UE session.

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.
