GeoLynx Spatial Router
NG9-1-1 Location Validation and Routing

Public safety GIS data plays a critical role in a Next Generation 9-1-1 (NG9-1-1) system. In i3 NG9-1-1 networks, all calls are routed based on location. NENA’s i3 Emergency Call Routing Function (ECRF) and the Location Validation Function (LVF) are core elements for NG9-1-1 call routing and location validation, and are provisioned with Geographic Information Systems databases.

GeoLynx Spatial Router determines the correct 9-1-1 PSAP a call should be routed to based on the location of the calling device. Caller locations can be geodetic coordinates such as lat/long point, polygon, circle, ellipse, arcband, or a civic address. The service information returned includes the service uniform Resource Identifier (URI) information for the service requested, which indicates which PSAP to route the call. i3 PSAPs can query the GeoLynx Spatial Router directly using LoST to obtain emergency service zone information to determine selective call transfer options for live 9-1-1 calls. Other 9-1-1 elements such as other ESRPs and ECRFs, LIS, and even calling devices can query GeoLynx Spatial Router with routing or validation queries, or to discover services.

GeoLynx Spatial Router supports all ECRF/LVF deployment models including direct (coalesced), indirect (forest guide), and hybrid models. In addition to being fully compliant with existing NENA i3 specifications for Next Generation 9-1-1, GeoLynx Spatial Router can also provide enhanced geographic intelligence to SIP routing proxies, such as spatial call cluster detection in the network.
