A portable telephone unitreceives management information comprising size information for contents data wanting to be downloaded, and adjusts an environment for receiving the object data, based on size information for contents data contained in the management information. To adjust the environment for receiving the object data it is possible, for example, to determine a communication system for receipt, or to secure a storage region for storing object data that has been received. After that, the portable telephone unittransmits a contents data download request, and receives contents data returned in response to the download request. As a result, it is possible for the communication terminal to download the contents data in a state where the receive environment has been optimized according to the size of the contents.

Data communication method, data communication system, and communication terminal

A cellular phonetransmits a request for management information including size information of object data which is desired to be downloaded, and determines whether a size of the object data exceeds a predetermined value or not, based on the size information. If the size of the object data does not exceed the predetermined value, the cellular phonestores the object data, received in response to the download request, in a temporary storage area. If the size of the object data does exceed the predetermined value, the cellular phonedetermines whether a free area for storing the object data in a permanent storage area exists or not. If a free area exists, the object data received in response to the download request is stored in the permanent storage area. As a result, the temporary storage area to be used for storing history is not used for storing a large amount of content data, and the history of a number of operations can be held in the temporary storage area without providing a large temporary storage area.
