INTRODUCTION/EXECUTIVE SUMMARY

This document contains standards for an ALI Service implementing the Emergency Information Services Interface (EISI) in an Emergency Services Network. An EISI consumer of this ALI Service can retrieve location information (ALI) and also report ALI discrepancy and misroute errors. The EISI consumer is an ESMI.RG (Response Gateway) entity in an ESMI-mediated configuration as defined in [1]. Otherwise any EISI entity may be an ALI Service consumer -- i.e., EPES or ECES entities.

This standard builds on the NENA ALI Query Service (AQS) interface specification as defined in [3], and more specifically on the SOAP binding of that interface (also defined as part of [3]).

The location information (i.e., ALI) retrieved by the ALI Service is structured according to the NENA XML ALI standard as defined in [4].
