    Abstract: The present technology is directed to establishing a connection between a client device within a 2G or 3G network and 5G core through an interworking function. The present technology can perform establishing a Gn-4G interworking function (IWF) between a client access network and a packet anchor network and performing one or more network functions through the Gn-4G IWF in providing a client of the client access network access to network services through the packet anchor network. The one or more network functions appear as one or more Gateway GPRS Support Node (GGSN) functions from the client access network (e.g., 2G or 3G network). The one or more network functions concurrently appear as one or more S4 Serving GPRS Support Node (SGSN) functions from the packet anchor network (e.g., 4G or 5G network).

    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: An example method is provided in one example embodiment and may include provisioning a user equipment (UE) with a list comprising one or more locations at which the UE is to report its location; reporting a location of the UE when the location is identified in the list; provisioning the UE with one or more access network selection policy based on the reported location of the UE; and applying at least one access network selection policy at the UE based on the location of the UE. The list comprising the one or more locations can be sent to the UE from an Access Network Discovery and Selection Function (ANDSF) server after the UE reports its location to the ANDSF server. The one or more access network selection policies can be permanent type and/or temporal type policies.
