Agenda Ø Ø Ø Ø 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 2

NCS Mission: EO 12472 Assignment of National Security and Emergency Preparedness Telecommunications Functions “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” 3

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

White House CWG Report July 2001 NS/EP Telecommunication Services Functional Recommendations Voice Band Service Interoperability Description The service must provide voice band service in support of presidential and other communications. Services must interconnect and interoperate with other selected government or private facilities, systems, and networks. Survivability/Endurability Services must be robust to support surviving users under a broad range of circumstances, from the widespread damage of a natural or man-made disaster up to and including nuclear war. International Connectivity Services must provide access to and egress from international carriers. Ubiquitous Coverage Services must be readily accessible to support the national security leadership and inter - and intra-agency emergency operations, wherever they are located. Enhanced Priority Treatment Services supporting NS/EP missions must be provided priority treatment over other traffic. Anonymity Selected users must be able to use NS/EP services without risk of usage being traced (i. e. , without risk of user or location being identified). 6

White House CWG Report July 2001 NS/EP Telecommunication Services Functional Recommendations Secure Networks Restorability Description Networks must have protection against corruption of, or unauthorized access to, traffic and control, including expanded encryption techniques and user authentication, as appropriate. Should a disruption occur, services must be capable of being reprovisioned, repaired, or restored to required service levels on a priority basis. Mobility The communications infrastructure must support transportable, redeployable, or fully mobile communications (e. g. , personal communications service, cellular, satellite, high frequency radio). Broadband Service The service must provide broadband service in support of NS/EP missions (e. g. , video, imaging, web access, multimedia). Scaleable Bandwidth Affordability Reliability/Availability NS/EP users must be able to manage the capacity of the communications services to support variable bandwidth requirements. Services must leverage network capabilities to minimize cost (e. g. , use of existing infrastructure, commercial off-the-shelf technologies, services). Services must perform consistently and precisely according to their design requirements and specifications, and must be usable with high confidence. 7

US-Canada WPS Interoperability Implementation ØLetter of Understanding (Lo. U) between NCS and Industry Canada to further WPS interoperability, coordinated with U. S. Department of State, and signed in July 2008 ØWireless 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 ØTested in Vancouver in Nov 2009 during Exercise GOLD to confirm readiness for the Olympic Games 15

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