Advanced triggers for location-based service applications in a wireless location system
First Claim
1. A method for use by a wireless location system (WLS) for locating a wireless device operating in a geographic area served by a wireless communications system, comprising:
- monitoring a set of predefined signaling links of the wireless communications system, wherein said predefined signaling links include at least an A link between a base station controller (BSC) and a mobile switching center (MSC) and a GSM-MAP link;
detecting at least one predefined network transaction involving a pre-set trigger occurring on at least one of said predefined signaling links; and
in response to the detection of said at least one predefined network transaction involving a predefined trigger, initiating at least one predefined location service.

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 monitoring a set of signaling links of the wireless communications system, and detecting at least one predefined signaling transaction occurring on at least one of the predefined signaling links. Then, in response to the detection of the at least one predefined network transaction, at least one predefined location service is triggered.
