Emergency services selective router interface translator

Abstract

A selective router interface translator for placement between legacy selective routers and their location databases translates location queries from legacy selective router interfaces to newer protocol location databases using newer protocol interfaces, e.g., a NENA V8 protocol query to an Emergency Routing DataBase (ERDB), or a Location to Service Translation (LoST) protocol query to a LoST server. In this way existing selective routers may remain as they are today, yet be flexible enough to allow the databases they query to be developed to new standards. The disclosed selective router interface translator includes a NENA V3 protocol to LoST protocol translator to translate a NENA V3 query for location of an emergency caller into a LoST protocol query. The selective router interface translator also comprises an ALI to ERDB protocol translator to translate an ALI query for location of an emergency caller into an ERDB protocol query.
