Abstract
A system may be configured to determine a floor of a building in which the user device is located at a time a call was placed. The information, indicating the determined floor, may be provided to a callee, such as a public safety answering point ('PSAP'). The floor may be determined based on, for example, comparing an altitude of the user device and/or a list of networks or devices that are visible to the user device, to a set of reference information.
