Abstract

An information processing device comprising: a communication module connectable to both a first cellular communication network and a second cellular communication network; and a control unit. when a failure occurs in the first cellular communication network, the control unit switches a communication network to be used to the second cellular communication network for a vehicle mounted application classified into a prescribed category from among a plurality of vehicle mounted applications that use the first cellular communication network.

First claim

What is claimed is:

1 . An information processing device comprising:
a communication module connectable to both a first cellular communication network and a second cellular communication network; and a control unit, wherein when a failure occurs in the first cellular communication network, the control unit switches a communication network to be used to the second cellular communication network for a vehicle mounted application classified into a prescribed category from among a plurality of vehicle mounted applications that use the first cellular communication network.

2 . The information processing device according to claim 1 , wherein the control unit continues use of the first cellular communication network for a vehicle mounted application that is not classified into the prescribed category.

3 . The information processing device according to claim 2 , wherein the prescribed category is a category related to safety.

4 . The information processing device according to claim 1 , wherein the control unit determines a category of the vehicle mounted application based on a communication message from the vehicle mounted application.

5 . The information processing device according to claim 1 , wherein the second cellular communication network is a communication network in which a basic usage fee is lower than a basic usage fee of the first cellular communication network and a communication fee per unit communication amount is higher than a communication fee per unit communication amount of the first cellular communication network.
