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: An example method is provided in one example embodiment and includes receiving, by a user equipment device, a list including at least one location identifier associated with an area for location reporting and an area identifier identifying the area for location reporting. The method further includes receiving a location identifier broadcast by a wireless network element, and determining whether the broadcast location identifier matches the at least one location identifier associated with the area for location reporting. The method further includes sending a location reporting message by the user equipment device to a first network node when it is determined that the broadcast location identifier matches the at least one location identifier associated with the area for location reporting. The location reporting message is indicative of the user equipment device either entering or exiting the area for location reporting.

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.

Abstract: The present disclosure is directed at systems, methods and media for relieving RAN congestion in a core network. In some embodiments, RAN congestion information is reported from user equipment to a packet data gateway (PGW) through an eNodeB and a software gateway. The PGW can aggregate the RAN congestion information and periodically notify other network nodes, for example, a PCRF, about the aggregate congestion in a network. By aggregating RAN congestion information, the PGW can substantially reduce the signaling required to report RAN congestion in the core network.

Abstract: The present disclosure is directed at systems, methods and media for providing QoS differentiation between IP data flows by sorting data packets into bearers. If a first node in a communication network (e.g., a User Equipment or UE) determines that downlink packets received from a second node (e.g., a Packet Data Network Gateway or PDN-GW) via a specific bearer should be given reflective bearer treatment, the first node can be configured to send uplink packets back to the second node via the same bearer. By sending uplink traffic using the same bearer as downlink traffic, the first node can aid in ensuring that the correct QoS for the uplink traffic is used. Downlink packets or bearers can be configured to request reflective bearer treatment through reserved QoS Class Identifier (QCI) values, Allocation and Retention Priority (ARP) values, or through an indicator specifically defined for requesting such treatment.
