PSAP. Log with time stamp of MSD presented Log with MSD content presented
PSAP. The term PSAP (Public Safety Answering Point) shall mean a location and facility providing the service and housing the equipment and personnel that provide E911 call-taking, teletype, and dispatching services.
PSAP. Log of MSD content (containing last two positions and heading) Within the post processing and evaluation process, the correctness of the heading information will be validated.
PSAP. Log of time stamp when request is initiated by PSAP operator Used VINs for the test Data sets received from EUCARIS Log of time stamp when data is presented at operator’s desk
PSAP. Log with time stamp of received eCall Log with indication of MSD received Log with indication of bi-directional voice communication Log with time stamp of end of eCall
PSAP. Log with MSD content presented Log with incident data sent to TMC
PSAP. Log with indication of bi-directional voice communication both during the initial call and during call-back D4.1 Draft KPIs, test specification and methodology Note: According to the standards, after the IVS will receive CLEARDOWN from the PSAP it will remain registered in the network for 60 minutes. In addition to testing the call-back capability it should be tested that the IVS won’t accept a call-back after this period of time has passed.
PSAP. Microphone and loudspeaker for communication with the IVS D4.1 Draft KPIs, test specification and methodology MSD decoding capability Possibility to initiate call-back Test sequence: Required:
1. IVS initiates an eCall
2. PSAP Operator answers the call and confirms bi-directional voice connection
3. PSAP Operator hangs up (CLEARDOWN will be sent to the IVS)
4. PSAP operator initiates call-back
5. PSAP Operator confirms bi-directional voice-connection
6. PSAP Operator hangs up again (CLEARDOWN will be sent to the IVS again) In the case the call drops before the PSAP Operator will initiate call- back (step 4) the results of the test will not be taken into consideration and that call will not be counted as a failed call-back.
PSAP. The PSAP simulator used to receive the test calls will collect log files about various events related to incoming test calls. At least the following events will be logged by the PSAP simulator for each test call: - opening of test call - start of MSD transmission - end of MSD transmission (transmission of link or application layer ACK) - voice channel established - closing of test call Information about an event will include the type of event, timestamp and possible supplementary data such as contents of the MSD.
D4.1 Draft KPIs, test specification and methodology A human user will answer the test calls at the PSAP used for testing and record the point in time when the contents of the MSD is presented, status of the voice connection and results of VIN decoding. eCall testing during the pilot will be accomplished as illustrated in the following figure: eCall client simulator or device prototype Control (Web) UI for eCall testbed Voice + MSD Configuration, logs • test users • configuration • result logs In addition to the eCall client simulator several other eCall clients may be used during the pilot. They may include both eCall client simulators and/or in-vehicle clients (if available). The clients used should include functionality for generating and sending standard eCall MSD (Minimum Set of Data) messages via the standardized in-band modem solution to the test number configured to the PSAP simulator (eCall test bed) During the tests, a Web user interface for managing the operation of the test bed will be used (see Figure 27). It will provide configurations for the test users, possibility to register the eCall clients (e.g. client phone numbers) used in the tests. Also, the pilot system operation can be managed via the user interface. It will also provide views to result logs. The log facility of the test bed will provide information about received messages (e.g. call time, modem session, duration, MSD information, warnings) and error cases. In particular, it will be used to validate the operation of the system as well as eCall clients.
D4.1 Draft KPIs, test specification and methodology The eCall pilot system can be directly used in cross borders activities that are planned to take place with one or two consortium partners. Also, eCall cross border tests with Russia (eCall compatibility, ERA GLONASS system) are planned. In practice, tests may be accomplished so that Finnish eCall Test bed is used as an eCall receiver (PSAP) and/or the eCall client simulat...
