This Handbook explains NG9-1-1 networks: functions that they provide; the environments in which they are implemented; and the process by which they can be built and maintained. It provides a comparison to Basic 9-1-1 and E9-1-1 systems that dominate the field of emergency services today. The reader is guided through an emergency call from its inception by the Caller to the Public Safety Answering Point (PSAP) Call Taker to Dispatch to First Responders, explaining how Basic 9-1-1, E9-1-1 and NG9-1-1 support each leg of this journey. Chapters explaining the underlying networks and the service standards provide details to those who need them for their daily work or as reference.
Next Generation 9-1-1 services are carried over data networks that use the Internet Protocol (IP) to establish communications flows between the calling and called parties. These flows are created in a fundamentally different way than are those created on the circuit switched networks that carry Basic 9-1-1 and E9-1-1 calls. The differences between packet switched and circuit switched networks are explained and the challenges and opportunities offered by creating call flows using packet switched networks are also described.
