NETWORK SUPPORT FOR RESTRICTING CALL TERMINATIONS IN A SECURITY RISK AREA

摘要

A precautionary measure against cell-phone triggered bombs is described that restricts call terminations within a designated security risk area without shutting down the entire network. Embodiments described herein provide for restricting call terminations directed to a designated security risk area that are originated from non- privileged users, i.e., the general public, yet authorizing call terminations directed to the security risk area that are originated from privileged government users (e.g., GETS/WPS users). Call originations are permitted within the security risk area from both privileged and non-privileged users.
