When an emergency situation takes place, information on the emergency situation may be collected by one or more network devices (not shown) and shared with the remote management server 20 and the EV 10 through the communication network 15. If the EV 10 receives the information on the emergency situation, it may transmit the same to the emergency subscriber device 100 of the EV 10. Examples of the information on the emergency situation, but are not limited: a location or time where the emergency situation has occurred, a content (e.g., car accident, fire, natural disaster, robbery, etc.) of the emergency situation, the number of deaths or injuries, or the like.
