摘要： A method for a mobile location center (MLC) to determine a location of a mobile device in a wireless communication network includes receiving a request 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, and receiving the GNSS measurements and at least one of the terrestrial measurements. A GNSS location of the mobile device is calculated as a function of the GNSS measurements, and the calculated GNSS location is determined to be the location of the mobile device when the calculated GNSS location meets a predetermined accuracy threshold. A terrestrial location of the mobile device is calculated as a function of the terrestrial measurements, and the calculated terrestrial location is determined to be the location of the mobile device when the calculated terrestrial location meets the predetermined accuracy threshold.
