First Claim
1. A method for use in controlling a mobile device'"'"'s access to a wireless communications network (WCN) with an overlaid wireless location system (WLS), comprising:
- monitoring a set of one or more predefined signaling links of the WCN;
detecting an event associated with said mobile device;
classifying the event as a periodic registration event for an idle mode device upon determining that periodic registration is enabled;
using a low-accuracy location function of the WLS, determining that said mobile device is within a defined area of interest and is potentially within a defined quiet zone;
using a high-accuracy location function of the WLS, determining a precise geographic location of said mobile device and based thereon determining that said mobile device is within said quiet zone; and
limiting the mobile device'"'"'s access to the WCN, said limiting comprising initiating call handling via an intelligent network associated with the WCN to indicate that, for incoming voice, SMS, or data session calls, the mobile device is unavailable.

Abstract
A method for use in controlling a mobile device'"'"'s access to one or more wireless communications networks (WCNs) with an overlaid wireless location system (WLS) includes monitoring a set of one or more predefined signaling links of at least one WCN, and detecting an event associated with the mobile device. Next, using a low-accuracy location function of the WLS, the system determines that the mobile device is within a defined area of interest and is potentially within a defined quiet zone. Next, using a high-accuracy location function of the WLS, the system determines a precise geographic location of the mobile device and based thereon confirms that the mobile device is within the quiet zone or at least within an area of ambiguity around the quiet zone. Finally, the mobile device'"'"'s access to the wireless communications network is limited, e.g., according to a pre-defined rule established by the carrier. This approach allows finer definition of the fenced area while also minimizing the load on the high-accuracy location function. The proximity threshold is preferably based on the accuracy of the underlying location technology.
