System and method for notification of 911 telephone calls using a link monitoring system

摘要

Notification of 911 telephone calls is provided to a telephone numbers listed on a pre-provided list of the telephone numbers without intrusion on the existing 911 infrastructure using the out-of-band SS7 signaling infrastructure. A link monitoring system (LMS) monitors SS7 messages to determine whether a 911 telephone call has been made. When the LMS determines that a 911 telephone call has been made, it sends a message containing calling party number information to a notification device. Using the telephone numbers provided on the notification list, the notification device notifies others that the 911 telephone call has been made.
