Abstract:
A method, a device, and a non-transitory storage medium provide an emergency call support service in which a network device of a visited network obtains user profile data of a wireless device from a home network of the wireless device, and provides the user profile data to a location server of the visited network. The emergency call support service allows an emergency call, when initiated by a roaming subscriber of the wireless device via the visited network, to include the user profile data and be provided to a public safety access point.
