An automotive emergency response system (AERS) for aftermarket devices defined in the Recommendation ITU-T Y.4119 is designed to bring rapid assistance to driver and/or passengers involved in accidents.
For a normal operation purpose of the AERS, an accident related data (so-called minimum set of data, MSD) needs to be sent from an automotive emergency detection device (AEDD) to an automotive emergency response center (AERC).
This Recommendation specifies an MSD transfer protocol to provide the rules of an MSD transfer operations between an AEDD and an AERC in an AERS.
