2. Introduction:National Security/Emergency Preparedness (NS/EP) users rely heavily on public telecommunications networks to facilitate recovery operations for natural and/or man-made disasters events. They need to make authorized calls anywhere, anytime in times of network congestion. As commercial telecommunications infrastructures have evolved to IP-based technology (e.g., IMS, POC, etc.), end-to-end priority services (e.g., voice, video, email, and data.) are needed to support NS/EP community.Problem Spaces:- End-to-end priority (i.e., distinguishing flows) - single domain (“own” resources), across domains- Security to ensure authorized ETS - Authentication, authorization, possibly confidentiality

3. Standards Efforts in Support of NS/EP Community:-IP Protocol Mechanisms: Internet Engineering Task Force (IETF) - WG’s that appear complimentary to NCS goals - IEPREP (informational) - TSVWG - SIP - NSIS- Regional Aspect: Alliance for Technical Industry Solutions (ATIS) - International Aspect: International Telecommunication Union – Telecommunication Sector (ITU-T)- Wireless Aspects: 3rd Generation Partnership Project / 3rd Generation Partnership Project 2 Potential Common Issues of Interests with DoD & NATO:- Interaction - Interconnectivity- Security
