RFI for U.S. Army Closed Emergency Service IP Network (ESINet)

The Systems Requirements Document (SRD) outlines technical requirements for the Department of Defense's (DoD) Global Public Safety Communications (GPSC) initiative. It focuses on the Public Safety IP Network (PSInet), Next Generation Core Services (NGCS), and Public Safety Answering Point (PSAP)/Emergency Communications Centers (ECC) to ensure interoperability with commercial emergency services IP networks (ESInet) using the NENA i3 framework. Key subsystems include the PSInet, NGCS, PSAP/ECC, Location Information Services (LIS), and Geographic Information Systems (GIS). The document details common protocol requirements for HTTP Enabled Location Delivery (HELD), Location-to-Service Translation (LoST), IPv6, and Session Initiation Protocol (SIP). It also specifies functional requirements for Core Session Policy Routers (CSPR) and Public Safety Policy Routers (PSPR), emphasizing call routing, location validation, and system availability. The SRD is a foundational document for JITC to certify systems for the DoD Unified Capabilities Approved Products List (APL), with continuous updates planned to maintain industry standards and interoperability.

The U.S. Army Contracting Command – Aberdeen Proving Ground (ACC-APG) is issuing a Request for Information (RFI) to conduct market research for establishing a closed Army Emergency Service IP Network (ESINet) with Next Generation Core Services (NGCS). This network will integrate with the existing Army Voice Modernization (VMOD) 2.0 infrastructure, replacing legacy 9-1-1 systems with a robust digital foundation. The RFI seeks industry input on technical approaches, deployment considerations, and estimated costs for this upgrade, which will support Army-owned and operated Public Safety Answering Points (PSAPs). The goal is to enable NG911 services, including multimedia data exchange, enhanced location accuracy, and improved resilience, while adhering to NENA i3 standards and Army Risk Management Framework (RMF) requirements. The information gathered will inform the government's understanding of technical feasibility, integration, scalability, and cost drivers for a potential enterprise-level strategy.
