Abstract

A control unit configured to perform obtaining a quality map regarding the quality of wireless communication for each planned travel route and area of the first vehicle, and transmitting an alternative route that does not pass through the first area to the first vehicle in response to the planned travel route passing through the first area whose quality of wireless communication is lower than a predetermined quality.

Claims (21)

1 . An information processing device comprising a processor configured to

acquire a planned travel route of a first vehicle to a destination,

acquire schedule information of a user of the first vehicle, the schedule information including a schedule of an online conference,

acquire a quality map related to quality of wireless communication for a plurality of areas,

determine whether the planned travel route passes through a first area of the quality map, the first area being an area where the quality of the wireless communication is lower than predetermined quality,

determine whether the online conference starts before the first vehicle arrives at the destination, and

send to the first vehicle a second route in a case where the planned travel route passes through the first area and the online conference starts before the first vehicle arrives at the destination, the second route being a route that does not pass through the first area.

2 . The information processing device according to claim 1 , wherein the first area is an area where a data transfer rate for either or both of downlink and uplink continues to be lower than the predetermined quality for a predetermined time or more.

3 . The information processing device according to claim 1 , wherein the processor is further configured to

collect probe data regarding a data transfer rate for downlink and uplink from a plurality of second vehicles, and

generate the quality map regarding the downlink and the uplink, based on the collected probe data.

4 . The information processing device according to claim 3 , wherein the probe data includes at least one of pieces of data that are periodically sent from wireless devices mounted on the plurality of second vehicles, the pieces of data being reference signal received power, reference signal received quality, and signal-to-interference-plus-noise ratio.

5 . The information processing device according to claim 3 , wherein:

the probe data further includes information about a measurement location of the data transfer rate and a measurement date and time of the data transfer rate; and

the processor is configured to generate the quality map for each time period.

6 . The information processing device according to claim 1 , wherein the processor is further configured to

calculate an interruption time, the interruption time being time required for the first vehicle to pass through the first area in a case where the vehicle is assumed to travel on the first route, and

notify the user of the interruption time via a display of the first vehicle.

7 . The information processing device according to claim 1 , wherein the processor is further configured to

calculate a time difference between a first traveling time and a second traveling time, the first traveling time being time required to reach the destination via the first route, the second traveling time being time required to reach the destination via the second route, and

notify the user of the time difference via a display of the first vehicle.
