Location services gateway server
View Patent ↗A method and apparatus for steering location requests to a serving one of a plurality of possible location positioning devices. A location request may be steered base on an emergency status of the location request, whether or not the subscriber device has a valid data plan established, based on the device type of the wireless device, or based on the type of application running on the wireless device. A location request may also be steered to a fallback location device if a steering to a primary selected location device fails and sufficient time remains to locate via the fallback location device.
1. A method of directing a location request in a wireless system to a serving location server based on emergency status, comprising:
steering a given location request to a first network-based location server if said location request is a non-emergency location request; and
if said location request is related to an emergency, instead steering said location request to a different, second network-based location server.
2. A method of directing a location request in a wireless system to a serving location server based on data plan status, comprising:
steering a location request of a subscriber wireless device that has a valid data plan, to a first network-based location server using a control plane; and
if said location request is related to a subscriber wireless device that has no valid data plan, instead steering said location request to a different, second network-based location server.
3. A method of directing a location request in a wireless system to a serving location server based on device type, comprising:
steering a location request of a subscriber wireless device of a first network protocol type, to a first network-based location server; and
if said location request is related to a subscriber wireless device of a second network protocol type, instead steering said location request to a different, second network-based location server.
4. A method of directing a location request in a wireless system to a serving location server based on application type, comprising:
steering a location request of a subscriber wireless device running an application of a first type, to a first network-based location server; and
if said location request is related to a subscriber wireless device running an application of a different, second type, instead steering said location request to a different, second network-based location server.
5. A method of directing a location request in a wireless system to a serving location server with a fallback, comprising:
steering a location request of a subscriber wireless device, to a first network-based location server; and
if said steered location request fails, and sufficient time remains, instead steering said location request to a different, second network-based location server.
