NETWORK STATE PREDICTION DEVICE, MOBILE COMMUNICATION SYSTEM, MOBILE COMMUNICATION METHOD, AND STORAGE MEDIUM
First Claim
1. A network state prediction device comprising:
- a database unit that stores first position information indicative of an end position on one side of a route on which a mobile communication terminal moves, second position information indicative of an end position on the other side of the route, and a network state indicative of a communication quality of a line to which the mobile communication terminal communicatively connects on the route, in a manner that the first position information, the second position information, and the network state are associated with each other;
a prediction target input unit adapted to input first input position information indicative of an end position on one side of a target route serving as a route to be predicted, and second input position information indicative of an end position on the other side of the target route;
a network state retrieving unit that retrieve from the database unit the network state on the basis of the first input position information and the second input position information, both of which are inputted through the prediction target input unit, and the first position information and the second position information, both of which are stored in the database unit; and
a prediction unit that generates network prediction information concerning the communication quality at the time when the mobile communication terminal moves on the target route on the basis of the network state retrieved by the network state retrieving unit.
