Next Generation Emergency
Services – Market Drivers
• Emergency service requests (9-1-1 calls)
– New methods of requesting emergency assistance
(e.g. VoIP, SMS, Call Relay Centers, E-mail, etc.)
– Enhanced capabilities of consumer devices
(e.g. display phones, text messaging, mobility, video)
• Technology modernization
– Existing aging infrastructure
– Easier integration of new technologies
– Enhanced communication capabilities
• Interoperability between service providing
agencies
• Enhance service response capabilities
– Information access and advanced services
Next Generation Emergency
Services – Market Drivers
• Broader integration between Government
agencies and E9-1-1
– Department of Homeland Security (DHS)
(National Response Plan, National Incident
Management System)
– Department of Transportation (USDOT) National
Telecommunications and Information Administration
(NTIA)
• Manageability, security, reliability, evolve-ability
• Cost, investment management, regulation

ATIS ESIF TF34 - Emergency
Services Network (ESNet)
• E9-1-1 Call Taker (PSAPs) voice and data
network services
– Creates options for deployment configurations and
service delivery
• Extend integration and collaboration to broader
community
• Mediates or facilitates access to services
– Opt-in subscription models
– PSAPs pulls info and controls information that can be
pushed
• Creates context for an emergency service request
– Emergency context over request and service response
• A foundation for additional value-add services
– Integrated voice and data via IP and VoIP technologies
– Extensible to deliver various application services
