Gateway apparatus and network system

Abstract

In a network system, only text data is displayed on a portable telephone when access is made to a page which is made public on the Internet by use of the portable telephone. An image of the page and information indicating a URL of the page are stored into a predetermined folder according to an instruction for storage of the page from the portable telephone based on the operation by the user.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application is a continuation of U.S. application Ser. No. 09 / 943,067, filed Aug. 31, 2001, the entire contents of which are incorporated herein by reference. [0002] This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2000-316786, filed Oct. 17, 2000, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION [0003] 1. Field of the Invention [0004] This invention relates to a gateway apparatus used for connecting a mobile terminal such as a portable telephone permitting a Web page and home page which is made public on the Internet to be read and a network system including the gateway apparatus. [0005] 2. Description of the Related Art [0006] Recently, mobile terminals such as portable telephones are widely used. Some of the mobile terminals have display sections constructed by small-sized liquid crystal display units and have elec...

AI Technical Summary

Benefits of technology

[0012] As described above, this invention has been made to solve the problem that communication traffic is increased and the communication cost becomes often wasteful if a page of a large data amount which is provided on Internet and is difficult to be displayed on the mobile terminal is fetched into the mobile terminal and an object of this invention is to provide a gateway apparatus and network system capable of displaying only displayable information on the mobile terminal and effectively utilizing information on Internet by use of a portable telephone while suppressing an increase in the communication traffic and preventing occurrence of the wasteful communication cost when a page provided on Internet is read by use of the mobile terminal.

Problems solved by technology

Further, pages other than the pages for the mobile terminals are often formed by use of image data having an extremely large data amount in comparison with text data.

Therefore, the following problems occur when pages other than the pages for the mobile terminals on Internet are read or observed by use of the mobile terminal such as the portable telephone.

(1) Since the mobile terminal has only a small display section, the page created on the assumption that it is displayed on the display section of the personal computer is difficult to be displayed on the display section of the mobile terminal.

(2) Since the memory capacity of a memory provided in the mobile terminal is small, the memory capacity becomes insufficient in some cases if a page created by use of image data having a large data amount is simply received and stored therein.

(3) In the mobile terminal such as the portable telephone, a charging system for making a charge according to a data amount of transmitted / received data is applied in many cases and if a page of a large data amount is received, communication traffic is increased, thereby causing the communication speed to be lowered or the communication cost to be raised.

Further, if data of the page which cannot be displayed is fetched into the mobile terminal, the communication cost becomes wasteful for the reasons described in the above items (1), (2).
