Abstract
Embodiments of the invention include a method for creating probe requests. The method is used when positioning is required. A short probe request is constructed with SSID set to GPS SSID_NAME. Another method continues after a short probe response is received. It is determined if a SSID of the probe response matches the SSID of the short probe request. If it does send an ACK.
Claims27
A method for creating probe requests, said method comprising:
- determining if positioning is required;
- and
- constructing a short probe request with a frame comprising a special prefix in the SSID_Name.
A method for creating a short probe response in an Access Point (AP), said method comprising:
- receiving of a probe request at said AP;
- determining if a SSID of said short probe request has a special prefix;
- and
- preparing a short probe response.
A device comprising:
- a transceiver;
- at least one antenna coupled to the transceiver for transmitting a signal over a wireless channel;
- a processor, coupled to the transceiver;
- a computer-readable medium including computer-readable instructions stored therein that, upon execution by the processor, perform operations comprising:
- determining if positioning is required;
- and
- constructing a short probe request with a frame comprising a special prefix in the SSID_Name.
A device comprising:
- a transceiver;
- at least one antenna coupled to the transceiver for transmitting a signal over a wireless channel;
- a processor, coupled to the transceiver;
- a computer-readable medium including computer-readable instructions stored therein that, upon execution by the processor, perform operations comprising:
- receiving of a short probe request at said AP;
- determining if a SSID of said short probe request having a special prefix;
- and
- preparing a short probe response.
A computer program product of computer-readable instructions, tangibly embodied on a non-transitory computer-readable medium and executable by a digital data processor to perform actions directed toward transmitting a signal, the computer-readable instructions configured to cause a device to:
- determine if positioning is required;
- and
- construct a short probe request with a frame comprising a special prefix in the SSID_Name.
A computer program product of computer-readable instructions, tangibly embodied on a non-transitory computer-readable medium and executable by a digital data processor to perform actions directed toward transmitting a signal, the computer-readable instructions configured to cause a device to:
- receiving of a short probe request at said AP;
- determining a SSID of said short probe request has a special prefix;
- and
- preparing a short probe response.
