PURPOSE • To Present the National Communication System’s (NCS) Contribution for Priority Access Service (PAS) in Wireless Networks to Support the Nation’s Vital National Security and Emergency Preparedness (NS/EP) Need Via a Wireless Intelligent Network (WIN)-Based Approach 2
National Security Telecommunications Advisory Committee Executive Office of the President Executive Agent (Secretary Of Defense) Office of the Manager, NCS (OMNCS) (Manager, Deputy Manager, Programs) NS/EP Support 30 Senior Executives from Industry 22 Federal Departments and Agencies CHAIR: Daniel P. Burnham President and CEO Raytheon Company A JOINT GOVERNMENT / INDUSTRY PLANNING PROCESS Provide Government-based Perspectives on NS/EP Issues for Telecommunications Provides Industry-based Recommendations to President on NS/EP Telecommunications NATIONAL COMMUNICATIONS SYSTEM (www.ncs.gov) OrganizationResponsible for Coordinating the Nation’s Critical National Security Emergency Preparedness Telecommunications 3
PRESENTATION OUTLINE • Basis for Need • FCC 2nd Report and Order for PAS • WIN Implementation of PAS (WIP) Overview • Recommendation/Next Steps 4
BASIS FOR NEED FOR PRIORITY RADIO CHANNEL ACCESS • Priority Access to Wireless Spectrum in Times of Heavy Demand is a Critical Requirement of NS/EP Telecommunications(Hurricanes, Terrorist Attacks, Flooding, Earthquakes, Tornadoes, War) • Radio Channel (at Access and Egress) Most Likely Point of Congestion and Area of Greatest Concern • Presidential Direction to NCS in Early 1995 to Implement Wireless Priority Services: • Cellular Priority Access Services Subgroup Formed under NSTAC Wireless Services Task Force • Both Government and Industry Involvement NCS Petition to FCC for Rulemaking - 19 October 1995 To Allow Authorized Priority Users to Gain Access to Next Available Open Channel Before Subscribers Not Engaged in NS/EP Functions 5

PRIORITY ACCESS SERVICE (PAS) FCC 00-242: 2ND REPORT AND ORDER http://www.fcc.gov/Bureaus/Wireless/Orders/2000/fcc00242.doc • Fully Responds to NCS’ 19 October 1995 Petition for PAS to Meet Nation’s National Defense and Security Need (effective 10 October 2000) • Allows Authorized NS/EP Users in Emergency to Gain Access to the Next Available Wireless Channel • Permits, But Does Not Require, CMRS Providers to Offer PAS to NS/EP Personnel at Federal, State and Local Levels and in Industry • Providers Choosing to Offer PAS are Required to Adhere to Uniform Operating Protocols • Providers May Limit PAS to a Portion of their Spectrum • Removes Major Liability Concerns for CMRS Providers Offering PAS • NCS to Have Day-to-Day Responsibility for Overall PAS Program (Order Lays Out Responsibilities for Service Providers and Users) CMRS (Commercial Mobile Radio Service) = Cellular, PCS, SMR, Paging, Satellite and Air-to-Ground 7
PAS DESCRIPTION Annex B, Part 64, Chapter 1, Title 47, Code of Federal Regulations Priority Access Service for National Security and Emergency Preparedness • Provides Means for Qualified and Authorized NS/EP Users to Obtain Priority Access to Available Radio Channels at Air Interface Access And/or Egress in a Call Path Involving Wireless When Necessary to Initiate Emergency Calls • To Be Available to Authorized NS/EP Users At All Times in Equipped Wireless Markets Where Service Provider Has Chosen to Offer Such Service • Authorized Users to Activate Feature on a Per Call Basis • To Be Used During Situations When CMRS Network Congestion is Blocking Call Attempts • Does Not Preempt Calls in Progress • Five Priority Levels Reserved for NS/EP Users, and These Users Provided Access to Wireless Channels Before Any Other Wireless Callers Qualified Users of PAS are those NS/EP personnel who meet the criteria of and have been assigned one of the five PAS levels as described in the FCC Order Authorized Users of PAS are those NS/EP personnel who have been validated for PAS through NCS Processes (Appendix A to SRD). 8
OMNCS OBJECTIVES FOR WIN IMPLEMENTATION OF PRIORITY ACCESS SERVICE (WIP) • Conformance with FCC Order for PAS • Provide NS/EP Users a High Probability of Access to Radio Channels during Emergency NS/EP Events Causing/Experiencing Severe Congestion • Minimal Burden to Vendors with Minimal Cost to Develop • Minimal Burden to Carriers with Minimal Cost to Deploy and Operate • As Quickly As Possible to Market with the Broadest Accessibility by Authorized Users • User Authorization Divorced from the Physical Device for Both Flexibility Today and Consistency With Future Technology Trends • Easy to Use 9
WIP: Stage 1 Overview • PAS Calls Encountering a No Radio (Voice) Available Condition in a Cell, At Access and/or Egress, Are Queued and Processed for the Next Available Channel in the Cell - Managed via a Service Logic Program (SLP) in a WIN SCP • Queued Call(s) are Processed by the Originating and/or Terminating MSC, as Appropriate, Based on Instructions from a WIN SCP and Supporting Message Flow between the MSC and SCP • PAS Calling Party Authorization and Priority Level Determination at Call Origination are Made by a Check in a PAS Field (or Fields) in a Database Maintained in an HLR, WIN SCP or Other Appropriate Platform 10
WIP: Stage 1 Overview (continued) • At Call Origination: • If No Radio (Voice) Channel Available, • If NS/EP User Authorized (via HLR, WIN SCP, Similar Platform), • If PAS Dialing Pattern Recognized, • Then Call Queued in SCP for Cell Serving the Calling Party, • Call Processed for Next Available Radio Channel in that Cell in Accordance with Caller’s Priority Level and Call Initiation Time, and • NS/EP Call Indicator(s) Set in Signaling to Mark as NS/EP Call. • At Call Termination: • If No Egress Radio (Voice) Channel Available, • If NS/EP Call Indicator Recognized in Incoming Call,(Indicator in Calling Party Category / ANSI-41 Signaling, etc.) • Then Call Queued in SCP for Cell Serving the Called Party, and • Processed For Next Available Radio Channel in That Cell. 11
WIP: Stage 1 Overview (continued) • Applicability to Telecommunications Services • PAS Applicable to Authorized NS/EP Voice Telecommunications Services that Require a Radio (Voice) Channel Assignment • WIP Applicable to Services that Employ WIN Technologies • PAS and Its Implementation via WIN May Be Applicable in Future to Other NS/EP Telecommunications (e.g., Data) 12
SUMMARY • NS/EP Users Have Urgent Need for Priority Access to the Air-Interface • FCC PAS Order Sets Stage for a Capability that is • Lawful, • Voluntary, • Addresses Carrier Liability, and • Fully Meets NS/EP Users’ Need • WIN Considered Most Appropriate Approach 13
RECOMMENDATION AND NEXT STEPSContribution to TR-45.2 Wireless Intersystem Operations Subcommittee Carol-Lyn Taylor Office of the Manager National Communications System Manager Wireless Priority Services 703-607-6187 Gilberto Frederick Office of the Manager National Communications System Wireless Priority Services 703-607-6187/6116 14 D-239-111500
RECOMMENDATION • That TR-45.2 Expeditiously Undertake This Work to Address the Nation’s Vital National Security and Emergency Preparedness Need • Forward to WIN Work Group (TR-45.2.5) for Action 15
NEXT STEPS • Provide Additional Details on Possible Approaches (via Appendix D to SRD) • Solicit Industry Assistance and Support • Receive Feedback from TR-45.2 16
