Next Generation Emergency Next Generation Emergency Services – Market DriversServices – 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 Next Generation Emergency Services – Market DriversServices – 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

• 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
