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.

First claim

What is claimed is:

1 . An information processing device comprising a control unit configured to
acquire a quality map related to quality of wireless communication for each planned travel route and area of a first vehicle, and when the planned travel route passes through a first area where the quality of the wireless communication is lower than predetermined quality, send to the first vehicle an alternative 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 required quality for a predetermined time or more.

3 . The information processing device according to claim 1 , wherein the control unit 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 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 control unit generates the quality map for each time.
