Method and apparatus for wireless network hybrid positioning

A system for location determination, the system comprising:

• a first mobile station comprising:
• a first transceiver;
• a first memory;
• and
• a first processor, wherein the first processor is communicatively coupled with the first transceiver and the first memory and configured to:
• receive, via the first transceiver, during a first time period,
• satellite positioning system (SPS) signals from SPS satellites;
• determine, during the first time period, one or more positions of the first mobile station based on the received SPS signals;
• receive, via the first transceiver, at the one or more positions of the first mobile station during the first time period, first wireless signals from a first access point of a first wireless network, wherein the first wireless signals received from the first wireless access point comprise identification information of the first wireless access point, wherein the first wireless network is a wireless local area network (WLAN), and wherein the first mobile station is not authorized to have access to the first wireless network;
• and
• transmit, via the first transceiver to a location server, information comprising the one or more positions of the first mobile station and the identification information of the first wireless access point;
• and
• a second mobile station comprising:
• a second transceiver;
• a second memory;
• and
• a second processor, wherein the second processor is communicatively coupled with the second transceiver and the second memory and configured to:
• receive, via the second transceiver, during a second time period after the first time period, second wireless signals from the first access point, wherein the second wireless signals comprise the identification information of the first wireless access point;
• determine positioning information with respect to the first wireless access point using the second wireless signals received from the first wireless access point, the positioning information comprising signal strength measurements, timing measurements, or both;
• transmit, via the second transceiver, to the location server, information comprising the identification information of the first wireless access point;
• receive, via the second transceiver, from the location server, location information of the first wireless access point;
• and
• determine a position of the second mobile station using the location information received from the location server and the positioning information.

A system of location determination, the system comprising:

• means for receiving, by a first mobile station, during a first time period, satellite positioning system (SPS) signals from SPS satellites;
• means for determining, by the first mobile station during the first time period, one or more positions of the first mobile station based on the received SPS signals;
• means for receiving, by the first mobile station, at the one or more positions of the first mobile station during the first time period, first wireless signals from a first access point of a first wireless network, wherein the first wireless signals received from the first wireless access point comprise identification information of the first wireless access point, wherein the first wireless network is a wireless local area network (WLAN), and wherein the first mobile station is not authorized to have access to the first wireless network;
• means for transmitting, from the first mobile station to a location server, information comprising the one or more positions of the first mobile station and the identification information of the first wireless access point;
• means for receiving, by a second mobile station, during a second time period after the first time period, second wireless signals from the first access point, wherein the second wireless signals comprise the identification information of the first wireless access point;
• means for determining, by the second mobile station, positioning information with respect to the first wireless access point using the second wireless signals received from the first wireless access point, the positioning information comprising signal strength measurements, timing measurements, or both;
• means for transmitting, from the second mobile station to the location server, information comprising the identification information of the first wireless access point;
• means for receiving, at the second mobile station, from the location server, location information of the first wireless access point;
• and
• means for determining, by the second mobile station, a position of the second mobile station using the location information received from the location server and the positioning information.

A non-transitory computer-readable medium storing instructions for location determination, the instructions comprising code for:
