1. A method comprising:
before an accident actually happens:
i) obtaining inputs from a pre-crash system (PCS) sensing function (PCSSF) in a user equipment;
ii) initiating a pre-emergency call procedure upon receiving, a PCS sensing indication from the PCSSF, wherein the PCS sensing indication informs that the accident has been estimated to happen based on the obtained inputs; and
iii) transferring a minimum set of data (MSD) to a network via an established pre-emergency call;
checking whether the accident happens for a time window;
transmitting a positive report to the network based on the accident actually having happened; and
transmitting a negative report to the network based on the accident not actually having happened, wherein the negative report informs that the PCS sensing indication is not followed by the accident.
