Abstract
Method and systems are employed by a wireless location system (WLS) for locating a wireless device operating in a geographic area served by a wireless communications system. An exemplary method includes defining a geo-fenced area. The method then includes monitoring a set of predefined signaling links of the wireless communications system, and detecting that a mobile device has performed any of the following acts with respect to the geo-fenced area: (1) entered the geo-fenced area, (2) exited the geo-fenced area, and (3) come within a predefined degree of proximity near the geo-fenced area. A high-accuracy location function may then be triggered in order to determine the geographic location of the mobile device.
