Next Generation 9-1-1 Status

Overall Deployment

NASNA's assessment model for measuring deployment of NG9-1-1 looks at three separate domains:

• The 9-1-1 Network: This describes the network that aggregates and routes 9-1-1 calls from originating service providers (OSPs) to public safety answering points (PSAPs). NASNA's assessment model looks at the deployment of an NG9-1-1 network through two key components: the implementation of an Emergency Services IP Network (ESInet), which serves as the Internet Protocol backbone of the NG9-1-1 network, and the Next Generation 9-1-1 Core Services (NGCS) which are the set of services needed to process a 9-1-1 call on an ESInet according to the NENA standard, also referred to as the NENA i3 standard.

• The Originating Service Providers (OSPs): This is the entire environment of telecommunications providers who provide service to end users and are the first entities to receive a 9-1-1 calls. OSPs allow callers to dial 9-1-1, then transmit that 9-1-1 call to the appropriate 9-1-1 network for delivery to the appropriate PSAP. NASNA's assessment model looks at whether OSPs are able to deliver calls to the 9-1-1 network in SIP (an internet protocol format) and whether OSPs are able to deliver calls in NENA i3 standard format with associated location in the SIP header, also referred to as the Presence Information Data Format - Location Object, or PIDF-LO.

• The Public Safety Answering Points (PSAPs): These are the individual 9-1-1 centers in each state that ultimately receive and process 9-1-1 calls placed by end users. NASNA's assessment model looks at whether PSAPs are able to receive 9-1-1 calls in SIP format and NENA i3 compliant format with PIDF-LO.

Each of the three domains has a maximum of 10 points that can be scored, for a total possible score of 30 points. Taken together, the deployment of Next Generation 9-1-1 systems is shown in the maps below. Deployment level is depicted with red indicating low levels of deployment and green indicating high levels of deployment, with yellow representing the middle. States that are not shaded in either did not respond to the survey, declined to respond to these questions, or NASNA lacked a contact for that state.

The first map below shows a combination of all three scores. It is taking into account the NG9-1-1 deployment scores for the 9-1-1 network (ESInet and NGCS), the Originating Service Providers, and the PSAPs.
