SERVER, CLIENT TERMINAL, AND INFORMATION PROCESSING METHOD
First Claim
1. A server, comprising:
- a storage configured to store communications quality information including communications quality of predetermined geographical areas on an area basis;
a receiver configured to receive information input to a client terminal, location information of the client terminal, and route information of the client terminal from the client terminal via a radio communication;
a processor configured to process a file based on the input information, and to predict quality of the radio communication with the client terminal on a route indicated by the route information of the client terminal based on the location information of the client terminal and the communications quality information; and
a transmitter configured to transmit an image to be displayed on the client terminal to the client terminal via the radio communication based on a result of processing the file by the processor,wherein the processor is configured to transmit first data to the client terminal if an interruption of the radio communication with the client terminal is predicted, the first data being at least a part of the file, and to receive second data from the client terminal after the radio communication with the client terminal is restored and to replace the first data with the received second data, the second data being the first data processed by the client terminal during the interruption of the radio communication.

Abstract
A server includes a receiver receiving the input information, location information, and route information of a client terminal; a processor processing a file based on the input information and predicting the quality of a radio communication with the client terminal on the route indicated by the route information based on the location information and stored communications quality information; and a transmitter transmitting an image to be displayed to the client terminal based on the result of processing the file. The processor transmits first data, which are at least part of the file, to the client terminal if an interruption of the radio communication is predicted. The processor receives second data, which are the first data processed by the client terminal during the interruption of the radio communication, from the client terminal after the radio communication is restored, and replaces the first data with the received second data.

3. A client terminal, comprising:
-
a receiver configured to receive first data from a server, the first data being at least a part of a file stored in the server; a file processor configured to process the first data during an interruption of a radio communication with the server; and a transmitter configured to transmit second data to the server after the radio communication with the server is restored, the second data being the first data processed by the file processor during the interruption of the radio communication, wherein the file processor is configured to delete at least one of the first data and the second data from the client terminal after the radio communication with the server is restored. - View Dependent Claims (4, 5)

6. An information processing method, comprising:
-
transmitting, by a client terminal, information input to the client terminal, location information of the client terminal, and route information of the client terminal to a server via a radio communication; processing, by the server, a file based on the input information, and transmitting, by the server, an image to be displayed on the client terminal to the client terminal via the radio communication based on a result of said processing; referring to, by the server, communications quality information including communications quality of predetermined geographical areas on an area basis, and predicting, by the server, quality of the radio communication with the client terminal on a route indicated by the route information of the client terminal based on the location information of the client terminal and the communications quality information; transmitting, by the server, first data to the client terminal if an interruption of the radio communication with the client terminal is predicted, the first data being at least a part of the file; transmitting, by the client terminal, second data to the server after the radio communication with the server is restored, the second data being the first data processed by the client terminal during the interruption of the radio communication; and replacing, by the server, the first data with the second data received from the client terminal. - View Dependent Claims (7)
