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). |
