Abstract: Systems and methods are provided for automatic PLMN serving system reselection based on E911 PSAP termination failures. For example, a UE may initiate a call for emergency services on a network provided by a cell site simulator. When the connection fails, metrics corresponding to the termination failure are communicated to the PLMN the next time the UE connects to a legitimate network. The fraudulent cell sites may be communicated by the UE to other UEs via peer-to-peer communication and/or added to an FPLMN list to prevent other UEs from connecting to networks provided by the fraudulent cell sites.

Abstract: Systems and methods provide for triggering an action based on detection of one or more user devices. One or more signals from at least one user device are detected by at least one sensor in a target area. A sensor can be in operable communication with a location server to which the signals are relayed. Based on the signals detected, a determination is made as to whether the one or more signals exceed a predetermined threshold for signal strength in the target area. Based on a set of signals exceeding the predetermined threshold for signal strength, the location server triggers an action that corresponds to the target area.
