System and method for location reporting in an untrusted network environment

摘要

An example method is provided and may include retrieving by a user equipment (UE) an access point (AP) Media Access Control (MAC) address for an AP to which the UE is connected; reporting location information for the UE to an evolved Packet Data Gateway over an SWu interface using Internet Key Exchange version 2 (IKEv2) protocol, wherein the location information includes, at least in part, a UE location in GPS coordinates, a service set identifier, the retrieved AP MAC address and cell identity information for the UE; and populating a location database with the location information. The method can include embedding the location information in an identity initiator (Idi) of an IKE Authentication Request (IKE_AUTH_REQ) message using a Network Access Identifier (NAI) and communicating the location information from the ePDG to a PGW over an S2b interface using a private extension information element of GPRS Tunneling Protocol version 2 (GTPv2).

1. A method comprising:
receiving location information for a user equipment (UE), wherein the location information includes, at least in part, a location of the UE, a Media Access Control (MAC) address for a particular access point (AP) to which the UE is connected in an untrusted access network and a cell identifier (ID) for a macro cell; determining that at least one of the location of the UE or the MAC address included in the location information is potentially invalid; comparing the cell ID for the macro cell received in the location information to cell IDs previously received for the UE for the location; determining whether the UE is moving based on the comparison; and populating a location database with the location information for the UE if the UE is determined to be moving.
