Abstract
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).
