Data processing method for portable communication terminal and portable communication terminal
First Claim
1. A data processing method for a portable communication terminal connected to a server over a communication network, comprising:
- predicting a future change in a communication state of a connection between the portable communication terminal and the server based on a record of communication speed recorded in reference to the connection;
determining a terminal processing level indicating a level of data which is permitted to be held in the portable communication terminal based on the future change in the communication state that has been predicted;
determining an importance level for each type of data of one or more types of data; and
limiting data to be held in the portable communication terminal based on the terminal processing level that has been determined and on the importance level that has been determined for each type of data.

Abstract
A terminal data storage section (18) of a portable communication terminal (10) stores the importance level of each piece of stored data. A connection state prediction judging section (12) predicts a change in the communication state of the connection to a server (20). A terminal processing level determining section (13) determines the terminal processing level of data based on the prediction result. When a data access becomes necessary, a data access managing section (15) determines whether a data access destination is the portable communication terminal (10) itself or the server (20) based on the importance level of the data and the then terminal processing level. When the terminal processing level is changed, a data hold managing section (14) deletes the data whose importance level is changed to an importance level which inhibits the data from being held at the changed terminal processing level from the terminal data storage section (18).

9. A portable communication terminal connected to a server over a communication network, comprising:
-
a terminal data storage section that stores an importance level of data to be held for each type of data of one or more types of data; connection state prediction judging section that predicts a future change in a communication state of a connection between the portable communication terminal and the server based on a record of communication speed recorded in reference to the connection; terminal processing level determining section that determines a terminal processing level of data to be processed in the terminal itself based on the future change in the communication state that has been predicted by the connection state prediction judging section; and a data access managing section that, when it is necessary to gain access to data that resides on one of the server and the portable communication terminal, determines a data access destination based on the importance level of the data to be accessed and on the terminal processing level that has been determined, and accesses the determined access destination. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
