Location continuity service for locating mobile devices using multiple access networks including wireless telecommunication networks

A location continuity application server comprising:

• one or more processors;
• and
• a plurality of modules configured to be executed by the processors to perform operations including:
• receiving a request for a location of a mobile device from an emergency service provider;
• responsive to the request,
• accessing from a first access network a first set of location data associated with a first position measurement for the mobile device;
• accessing from a second access network a second set of location data associated with a second position measurement for the mobile device;
• and
• combining the first set of location data with the second set of location data to determine the location of the mobile device;
• and
• providing the determined location to the emergency service provider,
• wherein the first set of location data defines a first geographic area and the second set of location data defines a second geographic area and the location is determined to be on a line connecting centers of the first and second geographic areas in an overlapping portion of the first and second geographic areas.

One or more non-transitory computer-readable storage media having computer-executable instructions stored thereon and configured to program a computing device to perform operations comprising:

• accessing from a first access network a first set of location data associated with a first position measurement for a mobile device;
• accessing from a second access network a second set of location data associated with a second position measurement for the mobile device;
• and
• combining the first set of location data with the second set of location data to determine a location of the mobile device,
• wherein the first set of location data defines a first geographic area and the second set of location data defines a second geographic area and the location is determined to be on a line connecting centers of the first and second geographic areas in an overlapping portion of the first and second geographic areas.
