Document description: 

The public safety community has recognized the need to evolve legacy emergency services networks to next generation concepts which may facilitate new capabilities and services. As such there are numerous industry associations and Standard Development Organizations (SDOs) that are defining architectures and protocols for these next generation networks. The public safety community desires to take advantage of this work and address the challenge it represents to emergency communications. To this end, work is progressing in other NENA committees to define the specific emergency services architectures and protocols involved. The transition of emergency services addressed by this document relies upon this collective work.

Transition to NG9-1-1(?) is expected to be an evolutionary process, involving technological, operational, economic, and institutional change. In some cases, the path to NG9-1-1 implementation will depend on the underlying infrastructure of the Public Safety Answering Point (PSAP)(?) and 9-1-1 Authorities involved. The NG9-1-1 environment may differ considerably from the current 9-1-1 environment.

Carriers and PSAPs may migrate independently to a next generation environment. This document addresses four use cases based on the transition status of the originating and terminating entities:
  • Carrier served by SR and PSAP served SR (current methods)
  • Carrier served by SR and PSAP served by NG9-1-1 system
  • Carrier served by a NG9-1-1 system and PSAP served by SR
  • Carrier and PSAP served by a NG9-1-1 system (fully transitioned)
