  7. REVIEW OF ACTIONS TO DATE • Overview to TR-45 Plenary 9 March 2000 • FCC 2nd Report and Order 3 July 2000 for Priority Access Service (PAS) • Overview to TR-45.2 14 August 2000 • Presentation Copy to CTIA for Review September/October • Presentation of SRD to TR-45.2 15 November 2000 Added to TR-45.2 2001 Work Candidates Forwarded to TR-45.2.5 for Review/Project Consideration • Update and SRD Overview to TR-45 29 November 2000 Remanded to TR-45.2 for Standard Development TR-45.4 and Authentication Group to Review/Comment • Presentation of SRD to TR-45.2.5 6 December 2000 SRD Standard Requirements Document 7

  8. 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 Origination and Termination) 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 8

  9. FCC 2ND REPORT AND ORDER FOR PRIORITY ACCESS SERVICE AND WIP STAGE 1 (Proposed) Overview for TR-45.2.5 WIN Working Group Max Puckett DynCorp Information Systems Wireless Engineering Manager GETS Integration Contract 703-818-5913 max.puckett@dyncorp.com 9

  10. 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 CMRS (Commercial Mobile Radio Service) = Cellular, PCS, SMR, Paging, Satellite and Air-to-Ground 10

  11. 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 Origination and/or Termination 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). 11

  12. NS/EP PERSONNEL • Individuals at Federal, State or Local Level, or in Private Industry, Whose Mission Supports: • National Security Leadership • National Security Posture and US Population Attack Warning • Public Health, Safety, and Maintenance of Law and Order • Public Welfare and Maintenance of National Economic Posture PAS to be Limited to Key Personnel and Those in NS/EP Leadership Positions - Not Intended for Use by All Emergency Service Personnel 12

  13. PAS PRIORITY LEVEL QUALIFYING CRITERIA 13

  14. 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 14

  15. WIP: Proposed Stage 1 Overview • PAS Calls Encountering a No Radio (Voice) Available Condition in a Cell, At Origination and/or Termination, 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 15

  16. Radio (Voice) Channel at Origination WIN SCP STP ORIGINATING MSC Q Switch/Mobility Manager Radio (Voice) Channel Traffic NS/EP User Signaling Cell Site PAS Call Queue at WIN SCP Q WIP: Proposed 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 NS/EP User, • Call Processed for the Next Available Radio Channel in that Cell in Accordance with the NS/EP User’s Priority Level and Call Initiation Time, and • NS/EP Call Indicator(s) Set in Call Setup Signaling to Mark as NS/EP Call. 16

  17. Radio (Voice) Channel Traffic Signaling PAS Call Queue at WIN SCP Q WIP: Proposed Stage 1 Overview (continued) • At Call Termination: • If No Radio (Voice) Channel Available, • If NS/EP Call Indicator Recognized in Incoming Call,(Indicator in SS7 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. NS/EP Call (PAS / HPC Indicator) Radio (Voice) Channel at Termination Q Switch/Mobility Manager WIN SCP STP Cell Site TERMINATING MSC 17

  18. WIP: Proposed 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) 18

  21. SUMMARY • NS/EP Users Have an 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 22

  22. RECOMMENDATION AND NEXT STEPS Overview for TR-45.2.5 WIN Working Group Carol-Lyn Taylor Office of the Manager National Communications System Manager, Wireless Priority Services 703-607-6187 taylor3c@ncs.gov 23

  23. RECOMMENDATION • That TR-45.2.5 Expeditiously Undertake This Work to Address the Nation’s Vital National Security and Emergency Preparedness Need by Requesting WIP Standard Development Project for 2001 from TR-45.2 24

  24. NEXT STEPS • Initiate Standard Development • Provide Additional Details on Possible Approaches (via Appendix D to SRD) • Continue to Solicit Industry Assistance, Support and Feedback • Provide Support to TR-45.2.5, and Others, in Standard Development 25
