Abstract: Systems, methods, and media for location reporting at a charging area level granularity are provided. The method includes detecting at a mobility management entity (MME) a transition of a user equipment (UE) from a first cell to a second cell to obtain at least a cell identifier. The method also includes determining at the MME whether the UE transition constitutes a transition from a first charging area to a second charging area using the cell identifier by comparing the cell identifier to a charging area configuration, wherein the second charging area includes a plurality of cells that are served by at least one eNodeB. The method further includes providing to a policy server a report of the UE transition, if it is determined that the UE transition constitutes a transition from the first charging area to the second charging area.

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.

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: Systems and methods are provided for avoiding excessive paging through messaging-based solutions on a mobile network that supports multiple radio access technologies (RATs), such as both Long Term Evolution (LTE) and Global System for Mobile Communications (GSM)/Enhanced Data Rates for GSM Evolution (EDGE)/Universal Mobile Communications System (UMTS) technology, even in situations where the present location of the UE is not known. Preventing paging in access networks where the UE is not present ensures efficient use of radio resources in the paging channel and reduces signaling load on other interfaces. In one embodiment, a user equipment (UE) is simultaneously connected to a Serving General Packet Radio System (GPRS) Support Node (SGSN) and a Mobility Management Entity (MME). By using signaling between the SGSN and MME, the location of the UE may be tracked without requiring unnecessary paging, even when the UE is in IDLE mode or is inactive.
