Claim:
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.
