Information processing device, information processing method, mobile terminal, and storage medium

An information processing method comprising:

• sending, by a computer mounted on a vehicle, abnormality occurrence information to a predetermined server through a first communication unit when an occurrence of an abnormality is detected in the vehicle, the abnormality occurrence information indicating the occurrence of the abnormality, the first communication unit being mounted on the vehicle and configured to perform communication via a base station using a first communication method;
• sending, by the computer, a proxy sending request to a terminal, the terminal being configured to communicate with a second communication unit by a second communication method, through the second communication unit when communication with the predetermined server cannot be performed through the first communication unit, the proxy sending request being a request to send the abnormality occurrence information to the predetermined server in proxy mode, the second communication unit being mounted on the vehicle and configured to perform communication using the second communication method that allows for terminal-to-terminal direct communication;
• and
• broadcasting, by the computer, the proxy sending request for a predetermined period when the communication with the predetermined server cannot be performed through the first communication unit.

A terminal comprising:

• a first wireless communication unit configured to perform communication using a first communication method via a base station;
• a second wireless communication unit configured to perform communication using a second communication method that allows for terminal-to-terminal direct communication;
• and
• a processor configured to
• receive a proxy sending request from an in-vehicle device through the second wireless communication unit, the proxy sending request being a request to send abnormality occurrence information to a predetermined server in proxy mode, the proxy sending request being a request broadcasted for a predetermined period, the abnormality occurrence information indicating an occurrence of an abnormality in a vehicle on which the in-vehicle device is mounted, and
• send the abnormality occurrence information to the predetermined server through the first wireless communication unit.
