Use Cases & Suggested Requirements for Non-Voice-Centric Emergency Services
The Emergency Services community has a desire to have multimedia
emergency services supported with the same general characteristics as
emergency voice calls. As a result, there is a need to communicate with
emergency services using mechanisms that are not primarily voice.
Non-Voice -Centric (NVC) Emergency Services are intended to support
(human) end user to authority communication. NVC Emergency Services may
support the following examples of non-verbal communications to an
emergency services network:
- Text communication between end users and emergency services
- Multi-media (e.g., pictures, video clips) transfer to emergency services during a voice or NVC session with emergency services.
- Real-time video session with emergency services
- Text communication with supplementary media (such as background audio and/or video)
NVC Emergency Services as defined in this document focuses on Next
Generation Network (NGN) technology and does not include legacy
messaging services, such as Short Messaging Service (SMS) . In addition,
NVC Emergency Services does not include support of calls from non-human
initiated devices (e.g., fire alarms).
There will be significant impacts to the entire emergency services
system resulting from the changes in networks and devices as described
in this document. It is expected that end user devices and origination
networks will ultimately evolve, and that the next generation emergency
services solution will allow this evolution to take place over time.
Many systems in the emergency services network must eventually change.
New end-to-end messaging relationships must be established.
In addition to supporting the general public, this capability
facilitates emergency communications by individuals with disabilities
(e.g., persons who are deaf, deaf-blind, hard of hearing, or have a
