Benefits of technology

"The present invention provides a method for providing a storage area in a storage server for a portable data terminal connected over a network. The method involves allocating a dedicated storage area for each user, storing software in the dedicated storage area of the user, and allowing the user to access the software through a site on the network. The method allows for easy addition of new software and allows the user to download required software without worrying about the internal storage capacity of the portable data terminal. The method also allows the user to expire the software after a set expiration date and charges the user for the software. The invention also includes a storage server connected to a network and a portable data terminal with local storage and a management table for software management. The technical effects of the invention include efficient storage capacity management, improved software sales, and flexibility for software updates."

Problems solved by technology

In addition, even if already stored software is erased when the internal storage capacity becomes insufficient, the same software may be downloaded again from the dedicated storage area and, therefore, the user may erase software without hesitation.
As a result, the user does not hesitate to purchase new software any more just because storage capacity is limited.

Embodiment Construction

[0044]A preferred embodiment according to the present invention will be described in detail below with reference to the drawings. In the description below, a cellular phone (including a PHS) with the data communication capability (Internet access capability) will be described as an example of a portable data terminal (hereinafter simply called a terminal). Basically, the characteristics of a portable data terminal to which the present invention is applied require that a part of internally stored applications cannot be rewritten by the user and that the contents of an application or data (including the tables that will be described later) to be operated upon only by the system cannot be illegally rewritten by the user. As long as the user cannot perform such an illegal operation, any unit other than a cellular phone such as a PDA (Personal Digital Assistant), a car navigation system, or a video game unit may be used. Alternatively, if the protection function against such an alteratio...

Abstract

A user-dedicated storage area (97) of a cellular phone (10) is retained in a storage server (9) on a network (6). Software purchased by a user via a sales server (12) is not transferred directly to the user's cellular phone (10) but is stored in the user-dedicated storage area (97) of the user. The user downloads the software from his or her own dedicated storage area (97) to his or her own cellular phone (10) before using the software.

Description

TECHNICAL FIELD[0001]The present invention relates to a portable data terminal with the data communication capability, and more particularly to a portable data terminal whose storage capacity of the internal storage device is relatively limited.BACKGROUND ART[0002]Recently, portable data terminals, such as cellular phones (including a personal handy-phone system called PHS) with the Internet access capability have been widely used. Those terminals make it possible not only to make voice communications but also to provide electronic mail transmission / reception services and various services via web site access. Considering the limitation on the display screen size of a cellular phone, more and more web sites have been prepared for cellular phones.[0003]Today, various services provided by web sites are carried out through online data transfer to and from web servers. However, because a cellular phone does not support the software capture capability that reads software from an external ...
