Abstract:
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.
Abstract:
The present invention provides a method for assigning an emergency temporary directory number to a roaming mobile unit (103). A request is received from a mobil unit (103) for an emergency temporary directory number. The communication system (100) determines if the request is a valid request. If the request is a valid request, the communication system (100) grants an emergency temporary directory number for the mobile unit (103). The communication system (100) then alerts the mobile unit (103) of the emergency temporary directory number.
