T he current 9-1-1 system is based on outdated analog network technology, employing methods originally designed for landline caller locations. This legacy system relies heavily on a tabular database of civic addresses called the Master Street Address Guide (MSAG), which is used to nd and validate the caller location against the MSAG location data and route the emergency call to the appropriate Public Safety Answering Point (PSAP). However, with over 80% of emergency calls now originating from mobile devices, the ability to validate caller locations and route calls to the correct PSAP has become problematic and in some cases tragic. The legacy system has added methods to help accommodate mobile locations (such as pseudo-locations for cellular towers and related cell sectors), but it lacks in both data completeness and currency to fully utilize the benets afforded by the location accuracy of modern cellular devices. The Motivation Behind NG9-1-1 Why Canada's Transition to NG9-1-1 is Needed The use of precise location data from GPS or Wi in mobile devices is lifesaving and necessitates the development of new methodologies for caller location, geodetic (device-based) call routing*, and emergency response procedures. Recognizing the necessity for advancement, Next Generation 9-1-1 (NG9-1-1) is the transformational change of 9-1-1 from the analog network technology to Internet Protocol (IP) technology, thereby enabling the foundation for geodetic call routing, which is slated to commence testing in late 2025 and is projected to achieve implementation by mid-2027. The road to NG9-1-1 establishes the criteria for achieving "NG compliant" status, which is a crucial step towards improving and modernizing emergency response using device-based location and enhanced call routing.
