Locating emergency calls via femto access points
Abstract
Techniques for routing an emergency call originated by a mobile station via a femto access point (FAP) in a wireless network and for locating the mobile station are described. In an aspect, the emergency call may be routed to an appropriate emergency center based on location information for the FAP. In one design, the location information for the FAP may include a macro cell identity (ID) and/or a macro Mobile Switching Center (MSC) ID determined based on the FAP location. The macro cell ID and/or the macro MSC ID may be assigned to the FAP and used to access a database, which may store routing information for emergency centers versus cell IDs and MSC IDs. In another design, the location information for the FAP may include a location estimate for the FAP. The location estimate may be used to access a geographic database, which may store routing information for emergency centers for different geographic areas.
