Claim Text:
1. A method for a mobile location center (MLC) to determine a location of a mobile device in a wireless communication network, the method comprising: receiving a request initiated by the mobile device to determine the location of the mobile device; concurrently requesting global navigation satellite system (GNSS) measurements from the mobile device and terrestrial measurements from transceivers in the wireless communication network; receiving the GNSS measurements and at least one of the terrestrial measurements; calculating a GNSS location of the mobile device as a function of the received GNSS measurements, and determining that the location of the mobile device comprises the calculated GNSS location when the calculated GNSS location meets a predetermined accuracy threshold; calculating a terrestrial location of the mobile device as a function of the received terrestrial measurements, and determining that the location of the mobile device comprises the calculated terrestrial location when the calculated terrestrial location meets the predetermined accuracy threshold; and calculating a hybrid location of the mobile device as a function of the received GNSS measurements and the received terrestrial measurements when neither the calculated GNSS location nor the calculated terrestrial location meets the predetermined accuracy threshold, and determining that the location of the mobile device comprises the calculated hybrid location when the calculated hybrid location meets the predetermined accuracy threshold.
