摘要： A wireless-global positioning system determines the location of a wireless mobile communication device from reliable position measurements and wireless network downlink measurements. The wireless network downlink measurements obtained are then used in conjunction with a database for pattern matching or contour matching. The difficulty of building and maintaining that database is alleviated by using those network downlink measurements associated with the reliable position measurements to populate the database, such as GPS measurements or those obtained through enhanced based positioning technique (EOTD). The increased database accuracy subsequently improves the quality of position location measurements from the wireless network.
