DRAFT9-1-1 InstituteWireless Networks
Committee

• Uniformity of Data Presentation
• and Delivery to PSAPs
• Lead Roger Hixson
• NENA Technical Issues Director

3
Uniformity of Wireless Data Presentation/
Delivery to PSAPs

• Why is uniformity important?
• Enables faster interpretation of wireless ALI
  data by the PSAP calltaker
• Enables more accurate 9-1-1 call handling, faster
  response
• Avoidance of mis-interpretation, potentially
  disasterous delayed response
• Less complication in establishing wireless E9-1-1

4
Uniformity of Wireless Data Presentation/
Delivery to PSAPs

• Several systems and data bases involved in the
  generation, processing, and provision of wireless
  data to PSAPs
• For Phase II
• MSC (Mobile Switching Center)
• PDE (Position Determination Entity)
• MPC (Mobile Positioning Center)
• ALI servers (Automatic Location Identification)

5
Uniformity of Wireless Data Presentation/
Delivery to PSAPs

• Lack of uniformity of data caused by
• Lack of detailed standards
• Insufficient forward-looking analysis
• Multiple party interpretations
• Varied expectations of PSAPs
• Major stakeholders (Roles covered in Issue
  Statement)
• Wireless carriers
• Wireless carrier vendors
• E9-1-1 System Service Providers (SSPs)
• Public Safety Entities (PSAPs, Counties et al,
  State Coordinators

6
Uniformity of Wireless Data Presentation/
Delivery to PSAPs

• Previous Work on this
  issue
• J-Standard 036 and updates
• Contains a level of data content and uniformity
  factors, but has proven insufficient (not enough
  user input)
• Not specific enough to minimize interpretation
  and variance issues
• Ad Hoc activity by vendors, ILECs, and some
  states
• NENA Data standards on data content and
  terminology, including a proposed addition for
  Wireless ALI Content, including future XML
  equivalency

7
Uniformity of Wireless Data Presentation/
Delivery to PSAPs

• Previous Work on this
  issue
• NENA Wireless Operations Committee recommendation
  on Phase I and II Features and Functions contains
  data recommendations
• ESIF Subcommittee F on standardizing messaging to
  the PSAP for type of wireless data, and extended
  text messaging
• Recent NRCI VII Subcommittee 1A on short term
  best practices may include data consistency

8
Uniformity of Data Presentation/ Delivery to
PSAPs

• Previous Work on this
  issue
• Gradual but limited improvements
• Some clarification of needed data items
• Missing
• Overall clarification and standards update for
  total wireless data items set

9
Uniformity of Data Presentation/ Delivery to
PSAPs

• Value of future
  work
• Enables faster interpretation of wireless ALI
  data by the PSAP calltaker
• Enables more accurate 9-1-1 call handling, faster
  response
• Avoidance of mis-interpretation, potentially
  disasterous delayed response
• Less complication in establishing wireless E9-1-1
• Less cost to establish and maintain wireless
  E9-1-1

10
Uniformity of Data Presentation/ Delivery to
PSAPs

• Regulatory / Government
  Issues
• Could result in controversy on data requirements
• Proponents better standardization will simplify
  implementation and operations of wireless E9-1-1
  for all stakeholders
• Opponents would cause delays in deployment and
  added vendor costs if the issue is confronted, at
  least in the short term

11
Uniformity of Data Presentation/ Delivery to
PSAPs

• OVERALL
• Corrections and improvement will be difficult at
  this stage of wireless E9-1-1 deployment time
  and attention
• Going-forward standards improvements could
  gradually improve the situation
• Care should be taken to accomplish proper
  standards development in future technologies
  affecting E9-1-1
