Claim:
A method for data communication of downloading data to a mobile communication terminal which is in a process of executing a browser application, comprising steps of: making a request for object-data management information, wherein the mobile 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 mobile communication terminal; judging a data size wherein the mobile 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, wherein when a judgment result at the step of judging the data size is negative, the mobile communication terminal transmits a request for downloading the object data; performing the first downloading to download the object data to the mobile communication terminal; storing a first object data, wherein the mobile communication terminal receives the object data and stores the object data in a temporary storage area which stores a history of the browser application, the temporary storage area being located in the mobile communication terminal; judging a free area, wherein, 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, the permanent storage area being located in the mobile communication terminal; when the judgment result at the step of judging the free area is negative, suggesting that a free space be secured and judging whether the free space has been secured; making a request for a second downloading, wherein, when a judgment result at the step of judging the free area is affirmative, the mobile communication terminal transmits a request for downloading the object data; and storing a second object data, wherein the mobile communication terminal receives the object data and stores the object data in the permanent storage area.
