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.

The present invention provides a system using an international roaming-capable mobile communication network in which a server controls the form in which a service is provided in accordance with the country of a service area in which a mobile station is located. The mobile stationdetermines the service area in which the mobile stationis located in accordance with a mobile communication mode set by a mobile communication mode setting function. Alternatively, the mobile stationdetermines the service area in which it is located through notification information relating to a mobile communication network system, received from a base station. When the mobile stationtransmits a request for a service to a content provider server, the mobile stationsimultaneously adds a region header describing the determined service area. A gateway G/Wmay add the region header instead of the mobile station

System using international roaming-capable mobile communication network

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.

When a command for starting up a specific versatile application of a versatile application section is made during an execution of a native application included in a basic processing section, a judgment of the following condition for combining is satisfied: whether or not the specific versatile application is in a paused state, and the specific versatile application has made a request for starting up the native application, is made (step S). When a judgment that the condition for combining is satisfied is made, an execution of the specific versatile application is restarted (step S). As a result, it is possible to have a prompt coordination between the basic processing section and the versatile application, while respecting a feeling of presence which is established in the mind of a user.
