Emergency Call Routing Function (ECRF)

A functional element in a NENA i3 system that uses the LoST protocol [RFC 5222] where location information (either civic address or geo-coordinates) and a Service URN serve as input to a mapping function that returns a URI used to route an emergency call toward the appropriate PSAP or responding agency based on the caller’s location.
