TTCN-3 based NG112 test system and playground for emergency communication

Great research efforts are made towards transferring additional data, such as location and sensor information, within the duration of an NG112 call. Especially in the field of emergency communication, the transmission of eHealth sensor data, which provide information about the vital parameters of a person in need of help, could improve the overall rescue operation. Since emergency calls are time-critical, it is necessary to analyse the impact of the attached sensor data on the emergency call system. In this paper, we present a TTCN-3 Test System that emulates smart devices by sending simulated sensor data via Bluetooth to a smartphone to trigger automated emergency calls. This emergency call is routed through an NG112 platform back to the Test System to measure the latency between sending the data and receiving the call. By incrementing the number of simulated sensors, the impact of the attached sensor data can be evaluated.
