US 11,115,784 B1 · Systems and methods for UE location and mobility

Abstract

Systems described herein provide techniques for establishing and modifying user plane communications sessions between Long-Term Evolution (“LTE”) User Equipment (“UE”) devices, connected to LTE base stations, and a Fifth Generation (“5G”) core network. An LTE-5G Interworking function (“LTE-5G IWF”) may logically generate a virtual 5G UE and/or 5G base station, map a LTE UE to the virtual 5G UE, and cause the establishment of a Protocol Data Unit (“PDU”) Session, at the 5G core network, with the virtual 5G UE. The LTE-5G IWF may also maintain a 5G context, including the information of the virtual 5G UE and/or 5G base station, based on the actual location of the LTE UE and/or an LTE base station to which the LTE UE is connected. The LTE-5G IWF may further update this context, including location information, when the LTE UE is handed over from one LTE base station to another.

Dependent claims

A device, comprising:

one or more processors configured to:
receive information indicating location information of a base station of a wireless network to which a User Equipment (“UE”) is communicatively coupled;
select a particular virtual base station, from a plurality of candidate virtual base stations, based on the received location information of the base station;
and
establish a user plane communication session between a core network and the UE, via the base station, wherein the user plane communication session is further associated with the selected particular virtual base station.
