METHOD FOR DATA COMMUNICATION,DATA COMMUNICATION SYSTEM AND MOBILE COMMUNICATION TERMINAL
First Claim
1. A method for data communication of downloading data to a communication terminal which is in a process of executing a browser application, comprising steps of:
- making a request for object-data management information, at which the communication terminal transmits a request for object-data management information which includes size information of object data desired to be downloaded;
receiving the object-data management information by the communication terminal;
judging a data size at which the communication terminal makes a judgment of whether or not a size of the object data exceeds a predetermined size, based on the size information of the object data;
making a request for a first downloading, at which when a judgment result at the step of judging the data size is negative, the communication terminal transmits a request for downloading the object data;
storing a first object data, at which the communication terminal receives the object data and stores the object data in a temporary storage area which stores a history of the browser application;
judging a free area, at which, when the judgment result at the step of judging the data size is affirmative, a judgment of whether or not there exists a free area for storing the object data in a permanent storage area in which stored data is not deleted when there is no explicit command from a user is made;
making a request for a second downloading, at which, when a judgment result at the step of judging the free area is affirmative, the communication terminal transmits a request for downloading the object data; and
storing a second object data, at which the communication terminal receives the object data and stores the object data in the permanent storage area.

Abstract
A cellular phone 10 transmits management information including size information of object data desirably downloaded, and determines whether a size of the object data exceeds the second predetermined value or not, based on the size information. If the result is negative, the cellular phone 10 stores the object data, sent back responding to download request, in a temporary storage area. If the result is affirmative, the cellular phone 10 determines whether a free area for storing the object data in a permanent storage area exists or not. If the result is affirmative, the object data sent back responding to the downloading request is stored in the permanent storage area. As a result, the temporary storage area to be used for storing history is not used any more for storing a large amount of content data, and number of histories held in the temporary storage area can be guaranteed.

6. A data communication system which downloads data to a communication terminal which is in a process of executing a browser application, wherein the communication terminal comprises
a means for making a request for object-data management information which transmits a request for object-data management information which comprises size information of object data desired to be downloaded; -
a data-size judging means which makes a judgment of whether or not a size of the object data exceeds a predetermined size, based on the size information of the object data;
a first-downloading means which, when a judgment result of the judgment made by the data-size judging means is negative, transmits a request for downloading the object data, and stores the object data which is sent back, in a temporary storage area which stores a history of the application;
a free area judging means which, when the judgment result of the judgment made by the data-size judging means is affirmative, makes a judgment of whether or not there exists a free area for storing the object data in a permanent storage area in which stored data is not deleted when there is no explicit command from a user; and
a second-downloading means which, when the judgment result of the judgment made by the free area judging means is affirmative, transmits a request for downloading the object data, and stores the object data which is sent back in response to the request for downloading, in the permanent storage area. - View Dependent Claims (7, 8, 9, 10)

11. A mobile communication terminal which is capable of executing a browser application, comprising:
-
a means for making a request for object-data management information which transmits a request for object-data management information which comprises size information of object data desired to be downloaded while executing the browser application;
a data-size judging means which makes a judgment of whether or not a size of the object data exceeds a predetermined side, based on the size information of the object data;
a first-downloading means which, when a judgment result of the judgment made by the data-size judging means is negative, transmits a request for downloading the object data, and stores the object data which is sent back, in a temporary storage area which stores a history of the application;
a free area judging means which, when the judgment result of the judgment made by the data-size judging means is affirmative, makes a judgment of whether or not there exists a free area for storing the object data in a permanent storage area in which stored data is not deleted when there is no explicit command from a user; and
a second-downloading means which, when a judgment result of the judgment made by the free area judging means is affirmative, transmits a request for downloading the object data, and stores the object data which is sent back in response to the request for downloading, in the permanent storage area. - View Dependent Claims (13, 14, 15)
