5. D-239-111500 BASIS FOR NEED FOR PRIORITY RADIO CHANNEL ACCESS 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  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 5

7. D-239-111500  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) PRIORITY ACCESS SERVICE (PAS) FCC 00-242: 2ND REPORT AND ORDER http://www.fcc.gov/Bureaus/Wireless/Orders/2000/fcc00242.doc CMRS (Commercial Mobile Radio Service) = Cellular, PCS, SMR, Paging, Satellite and Air-to-Ground 7

8. D-239-111500 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 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  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

9. D-239-111500  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 OMNCS OBJECTIVES FOR WIN IMPLEMENTATION OF PRIORITY ACCESS SERVICE (WIP) 9

10. D-239-111500 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

11. D-239-111500 WIP: Stage 1 Overview (continued) 11  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.

12. D-239-111500 Applicability to Telecommunications Services PAS Applicable to Authorized NS/EP Voice Telecommunications Services that Require a Radio (Voice) Channel Assignment PAS Applicable to Authorized NS/EP Voice Telecommunications Services that Require a Radio (Voice) Channel Assignment WIP Applicable to Services that Employ WIN Technologies 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) PAS and Its Implementation via WIN May Be Applicable in Future to Other NS/EP Telecommunications (e.g., Data) WIP: Stage 1 Overview (continued) 12

13. D-239-111500 SUMMARY 13  NS/EP Users Have Urgent Need for Priority Access to the Air-Interface  FCC PAS Order Sets Stage for a Capability that is  WIN Considered Most Appropriate Approach  Lawful,  Voluntary,  Addresses Carrier Liability, and  Fully Meets NS/EP Users’ Need
