File distribution system and method thereof
First Claim
1. A file distribution system comprising:
- a file distribution device and a plurality of terminals, wherein said plurality of terminals are subordinately interconnected to said file distribution device;
said file distribution device comprising;
a type/version management unit operable to receive information of a data file version of a terminal together with information of a hardware type of said terminal transmitted from said terminal and directly referencing thereto, thereby deciding the file version and the hardware type of said terminal;
a file storage unit operable to store distribution files to be distributed to said terminal when requiring a version up thereof;
a rank information storage unit operable to store rank information of the distribution files and to rank the distribution files in levels, wherein the distribution file rank information stored in the rank information storage unit has a data structure composed of a distribution file ID and rank information indicating a degree of significance of a distribution file; and
a file extracting unit operable to selectively extract a referenced distribution file from the distribution files stored in said file storage unit based on the decision result made by said type/version management unit.

Abstract
In a file distribution system, an information management unit (10) receives information of a data file version of a target terminal (2) together with information of the hardware type of the terminal (2) and directly references thereto, thereby deciding the file version and hardware type of the terminal, and a file extracting unit (11) selectively extracts a referenced distribution file from the distribution file based on the decision result made by the information management unit (10), and the reference versions of the distribution files together with hardware type information of the terminal are installed in the distribution side without installing the information of the file versions of the terminal.

9. A file distribution method for distributing a file from a file distribution side to a file receiving side, said file distribution method comprising:
-
searching information of version data and hardware type information upon receipt of the version data and hardware type information from the file receiving side;
judging whether or not the file to be distributed exists in the file distribution side;
deciding a kind of hardware of a terminal and a file version of the file receiving side;
judging, based on the decision result made by said deciding, whether or not there exists a file to be distributed to the file receiving side;
obtaining a corresponding rank of the outstanding file from file rank information stored at the file distribution side, wherein the distribution file rank information stored at the file distribution side has a data structure composed of a distribution file ID and rank information indicating a degree of significance of a distribution file;
judging whether or not the decision of the file distribution can be performed by the file receiving side;
informing the file receiving side that there exists a file to be distributed; and
extracting a desired distribution file with reference to the hardware type and version management information based on the version data transmitted from the file receiving side. - View Dependent Claims (10, 11)
