In one embodiment, the apparatus and methods support location-based services requiring indoors or underground positioning (or other applications which cannot be served by GPS/A-GPS or GLONASS), such as via Wi-Fi Location devices with fine timing measurement (FTM) capability. A cable, terrestrial or satellite network operator can obtain location data on e.g., an LTE-enabled UE with SIM capability located within a served premises or venue, via an HTTP/S GET protocol, and forward the location data. In one variant, a managed 3GPP IP Multimedia System (IMS) infrastructure is used in conjunction with UE-specific identifiers under control of a controller entity (e.g., ePDG) in communication with the IMS infrastructure and one or more FTM-enabled Wi-Fi APs within the premises or venue for supporting VoWi-Fi 911 or 411 packet calls made via the IMS."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and methods for device location determination","description":"Apparatus and methods for provision of location-based services to wireless device users.
