Mayday/9-1-1 Field Operational Test (FOT) Results and Path Forward Report

Within the United States, there are significant, well-acknowledged challenges in routing and delivering Telematics Service Provider (TSP) emergency calls, and associated vehicle location and crash data information, across the nation to the appropriate local Public Safety Answering Points (PSAPs) using the local, native 9-1-1 networks. The 9-1-1 networks are local, disconnected from each other, and are not coordinated at a national level. Telematics calls traverse long distances, far from the location of the emergency, to the national, centrally located Telematics Call Center (TCC) of the TSP. Once at the TCC, there is no existing, effective way to route these calls back to the appropriate, local 9-1-1 network as an emergency call. Today, the TSP emergency calls are routed via the Public Switched Telephone Network (PSTN) to an administrative line on the appropriate PSAP. This is accomplished by the TCC using a lookup table for these administrative telephone numbers in a database that must be kept up to date. Since these calls come in on the administrative line, the PSAP may not give them the same priority as normal arriving 9-1-1 calls. Since these calls are PSTN voice only, many of the data features associated with 9-1-1 networks interconnecting to wireless and wireline networks are not available between the TCC and PSAPs. All of the emergency information must be provided to the PSAP operator verbally which can lead to mistakes and delays. The TSP Emergency Call Routing Service (TSPECRS) System Specification and Concept of Operations provide more details on this service, and the type of information and data that the TSPs wish to send to the PSAPs. The TSP Emergency Call Routing Service (TSPECRS) System Specification specifies the architecture, interfaces/protocol and system requirements to facilitate routing of a TSP emergency call to the appropriate 9-1-1 network and PSAP, by utilizing the Serving Wireless Service Provider (WSP) network. TSPECRS allows a TCC to make TSP emergency calls via the wireless network (and the PSTN), and make them appear as wireless E9-1-1 Phase 2 calls to the PSAPs. In addition, the TSPECRS System Specification describes procedures that would facilitate transmission of TSP crash data to the PSAPs via the signaling network of the WSP. This document presents results from the Mayday/9-1-1 Field Operational Test (FOT) effort from the point of view of the operational team conducting the FOT. This document supports the proof of concept demonstration and testing environment of the Mayday/9-1-1 FOT for the voice routing functionality.
