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, 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 includes gateways and methods for node selection of virtual network nodes in virtual evolved packet core networks. The methods include receiving, at a gateway from an evolved Node B (eNodeB), an attach request for a user equipment (UE), and determining a network selection hint corresponding to the received attach request, where the network selection hint is used for determining a virtual network node for selection in a mobile cloud network. The methods further include determining a domain name for establishing a network connection based at least in part on the network selection hint, where the selected domain name is associated with a virtual network node in the mobile cloud network. The methods also include selecting a virtual network node associated with the determined domain name, and establishing a network session to the selected virtual network node.
