Voice over internet protocol (VoIP) E911 metro street address guide (MSAG) validation |
摘要 |
An overlay list of MSAG-valid addresses is created for use in lieu of (or in addition to) the lat/Ion or postal address which otherwise would go with an E911 VoIP 911 call. This overlays the nation with a series of MSAG-addressed polygons, with center points identified in those polygons, and MSAG-valid addresses provided to the PSAPs for those centers, preferably along with the original latitude/longitude coordinates. |
