  1. Office of the Manager, NCS NGN Priority Services Efforts Presentation to CSRIC Frank J Suraci GETS/WPS Prog Mgr March 22, 2010

  2. Agenda • NCS Mission • Emergencies and Network Congestion • NCS Process for NGN Priority Services • NGN PS Industry Requirements and Standards • Interoperability Testing, Studies, and Prototyping • Realization of NGN Priority Services • Summary

  3. Assignment of National Security and Emergency Preparedness Telecommunications Functions NCS Mission: EO 12472 “The mission of the NCS shall be to assist the President, the National Security Council, the Homeland Security Council, the Director of the Office of Science and Technology Policy and the Director of the Office of Management and Budget in the … provision of national security and emergency preparedness communications for the Federal government under all circumstances, including crisis or emergency, attack, recovery and reconstitution”

  4. Emergencies Can CauseNetwork Congestion Congestion, at any one of many points, can block a call! PBX AT&T VzB SPRINT Local Exchange Networks Local Exchange Networks Mobile Switch Mobile Switch GETS addresses wireline congestion FCC R&O For PAS WPSaddresses wireless congestion at call origination and call termination

  9. Status of NGN PS Industry Requirements & Standards • SIP Resource Priority Header - IETF RFC 4412 Feb 2006 • IMS Core Network IR Phase 1 - Priority Voice Dec 2007 • Sections provided to ATIS for Standards • SIP RPH Requirements Matrix / Gateway (IP-TDM) ATIS-1000023.2008 • Access Network IRs Final Drafts Target - April 2010

  10. Industry – NCS NGN Prototyping • Proof of Concepts: • Global MSF Interoperability Events 2004, 2006, 2008 • Transfer/encapsulation of priority signaling • Use of NS/EP Parlay APIs • Priority Voice and Priority Video • Authentication Techniques • Anonymity • Verizon Interoperability Forum lab demonstration of NGN priority for 800 numbers - Sep 2007 • Sprint lab demonstration of priority services on IMS core - Mar 2009 • NCS Experimental Test Environment (XTE) Lab • Demonstrations of softswitches, SBCs, routers, congestion, and priority voice, video and data

  11. PSTN Access Network / Internet Possible Threats to IMS Networks • Application Servers • Un-patched App/OS Exploits • Authentication & Authorization Flaws • Third Party Application Access • Malicious Applications • Authentication & Authorization Flaws • Insecure Partner Networks • Proxy Servers • User Impersonation • SIP Parameter Manipulation • Denial of Service • Control Servers • Signaling Weaknesses • Mgt Vulnerabilities Core Network • Network Attachment • Weak Authentication • Policy Mis-configuration • IP Attacks • Back-End Systems • Location Misdirection • Information Storage • Weak App-to-App Authentication • Web Servers • Inadequate Input Validation • Authorization Flaws • Insecure Sessions • Access • Eavesdropping • Man-in-the-Middle Attacks • Session Hijacking • User Device • Worms/Viruses • OS Vulnerabilities • Network Impersonation 11

  12. NCS Standards and Forum Participation Objectives: • Augment existing (or define new) protocols to support Prioritization, Service Assurance, Security Actions: • Standards contributions and review related to Emergency Telecommunications Service (ETS) • IETF • ITU-T • ATIS • 3GPP/3GPP2 • IEEE • WiMAX Forum • MultiService Forum

  13. Interoperability • Interoperability with other networks • Defense Switched Network • Diplomatic Telecommunications Service • FTS/Networx • US - Canada WPS interoperability

  15. US-Canada WPS Interoperability Implementation • Letter of Understanding (LoU) between NCS and Industry Canada to further WPS interoperability, coordinated with U.S. Department of State, and signed in July 2008 • Wireless Priority Service (WPS) interoperability between the U.S. and Canada provides priority to cross-border roaming of US WPS GSM subscribers of AT&T Mobility and T-Mobile within Canada serviced by Rogers Wireless • Tested in Vancouver in Nov 2009 during Exercise GOLD to confirm readiness for the Olympic Games

  16. Summary • NCS has worked with industry (vendors & service providers) to define the priority capability requirements • NCS and industry both are working with Standards Bodies to incorporate NS/EP priority capabilities into standards • NCS has participated in industry-sponsored interoperability test events and prototyping of priority requirements • NCS has funded some vendors and carriers for development of initial NGN priority capabilities

  19. Evolution of PSTN Incorporate IETF standards Install packet switching architecture Support variety of applications Not just voice! IP Multimedia Subsystem (IMS) Realization of NGN by today’s U.S. carriers VoIP is initial service offering Initial target for NS/EP prioritized communications Legacy PSTN 1 1 2 2 3 3 1 2 3 4 4 4 5 5 5 6 6 6 7 7 7 8 8 8 9 9 9 8 8 8 # # # * * * Next Generation Networks (NGN) Migration to NGN Legacy PSTN G/W Wireless Access IMS Core (UE) * NGN Carrier Shared IP Infrastructure Wireless Access Internet * caveat: internal structure and connectivity is carrier dependent. In addition IMS shall be realized in various stages and continue to evolve.

  21. Status of NGN PS Industry Requirements & Standards

  22. NCS Participation in ATIS and TIA • Membership in ATIS and TIA • Objectives • Develop National technical and operational standards (services, architecture, signaling) • Augment existing (or define new) protocols to support: • Prioritization, Service assurance, Security • Develop Interconnection and Interoperability operational procedures, test procedures • Actions • TIA & ATIS Standards contributions in support of NS/EP requirements

  23. Forums • MSF • Specifies network architectures, interfaces (implementation agreements) and test scenarios • Prototypes and tests service concepts (e.g., priority invocation, authorization, call completion in VoIP, video) in multi-vendor environments • Telemanagement • Advances work in Service Level Agreements in support of network to network interoperability
