Embodiment Construction

[0013] overview

[0014] In an example embodiment, a method is provided, and the method may include: retrieving, by a user equipment (UE), an AP medium access control (MAC) address of an access point (AP) to which the UE is connected, wherein the The AP is in an untrusted Internet Protocol (IP) access network; using the Internet Key Exchange Version 2 (IKEv2) protocol to report the location information of the UE to the Evolved Packet Data Gateway (ePDG) through the SWu interface, where the location information at least partially includes: The location of the UE in Global Positioning System (GPS) coordinates, the service set identifier (SSID) of the untrusted IP access network, the retrieved AP MAC address, and cell identification (ID) information for the UE; and The UE's location information populates a location database, wherein the location database at least partially includes location information of other UEs in the untrusted IP access network.

[0015] The method may in...

Abstract

The present disclosure provides systems and methods for location reporting in an untrusted network environment. An example method is provided and may include: retrieving, by a user equipment (UE), an AP media access control (MAC) address of an access point (AP) to which the UE is connected; using an Internet key exchange version 2 (IKEv2) protocol reports the location information of the UE to the evolved packet data gateway through the SWu interface, wherein the location information at least partially includes: the UE location in GPS coordinates, the service set identifier, the retrieved AP MAC address, and the cell identification information; and populate the location database with the location information. The method may include using a Network Access Identifier (NAI) to embed the UE's location information into an ID Initiator (Idi) of an IKE Authentication Request (IKE_AUTH_REQ) message and using a proprietary extension of GPRS Tunneling Protocol Version 2 (GTPv2) The information element transmits the location information of the UE from the ePDG to the PGW through the S2b interface.

Description

technical field [0001] The present disclosure relates generally to the field of communications, and more particularly to systems and methods for location reporting in untrusted network environments. Background technique [0002] Networked architectures in communication environments, especially mobile wireless environments, have become increasingly complex. As end users become increasingly connected to the mobile wireless environment to do business, shop, interact with friends, maintain personal finances, and perform many other everyday functions, mobile communication networks have grown substantially in subscriber base. As the number of mobile subscribers increases, efficient management of communication resources becomes even more critical. In some instances, management of resources relies on the service provider knowing where the subscriber is connected to the network. Subscriber location is also required for lawful interception. There are significant challenges to knowi...
