ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an information provision system for providing information such as guide information and geographical information to users by means of display and others if a user makes a request and an information regenerator used for the above system.
The present invention also relates to a method and a system of data communication such as facsimile communication and electronic mail using a mobile radiocommunication network for Japanese personal handyphone system (PHS) and mobile telephone for example, a communication terminal and a server used for the above system.
2. Description of the Related Art
A portable information processing display terminal such as an electronic notebook is widely popularized. As for such an information processing display terminal, a user can utilize provided information at necessary time and in a necessary place because various provided information is stored in an internal memory. However, as such an information processing display terminal is portable, a mass memory cannot be provided as to an internal memory and the quantity of providable information is limited. As provided information cannot be updated without rewriting contents stored in a memory or without replacing memories, it is difficult to acquire the latest information.
The former problem of the capacity of memory can be improved to some extent by storing provided information in a card according to PC Card Standard for example, providing a card reader to a portable information processing display terminal and exchanging cards. However, in this case, a user is required to buy plural cards in which various information including information low in a frequency is stored and a user is economically burdened. In addition, to acquire the latest information, a user is required to buy a card in which new information is stored and bears an economic burden.
In the meantime, recently various information provided to the Internet is often acquired by a personal computer via a modem and is often regenerated on the screen of a display or via a speaker. If a personal computer has only to have a memory area in which extracted information can be stored in case information provided to the Internet is utilized, a personal computer can utilize information, the personal computer can utilize information and a terminal itself is not required to have a mass memory.
A portable information processing display terminal to which a modem and data communication facility are added and which can acquire information provided to the Internet in view of the advantages of utilizing information provided to the Internet is also provided.
If information provision service via the Internet is demanded, generally, a user of a personal computer and a portable information processing display terminal makes a contract of information provision service with a specific Internet service provider (hereinafter called ISP). When the above user receives actual information provision service, he/she can receive providable information from an ISP server by accessing to ISP under the above contract so as to connect ISP and his/her own terminal and requesting the provision of information.
In this case, information which individual ISP can provide is limited to information which ISP collects from the provider of contents who subscribes to the network of the ISP and with which ISP itself is provided. Therefore, when information which cannot be obtained from one ISP is required, a user is required to make a contract with ISP which can provide the information separately.
As a user is required to select ISP depending upon required information and access to the selected ISP in a situation in which the user makes a contract with plural ISPs as described above, he/she is required to remember what information each ISP can provide and operation to request the provision of information is troublesome.
The specification of provided information may be different every ISP and if a terminal receives information provision service from plural ISPs as described above, the terminal is required to be provided with an application program according to the specification of each information and hardware according to circumstances. The above point is particularly a problem in the case of a portable information processing display terminal in which the reduction of the load of an application program and the simplification of hardware are important.
Radio data communication service in which the radiocommunication of various data such as text data and image data in addition to voice communications is enabled takes notice because of the popularization of a portable radiocommunication terminal such as a PHS terminal and the speedup of the transmission speed of data communication using these portable radiocommunication terminals.
In case a PHS terminal is used, data communication in the approximately same transmission speed of 32 kbit/s as the transmission speed of 28.8 kbit/s or 33.6 kbit/s in case a modem is used on an analog telephone line is enabled and the communication of an electronic mail, facsimile transmission and others are enabled outdoors via a portable radiocommunication terminal.
For facsimile transmission, a so-called FAX modem is required to be mounted and there is a problem that a portable radiocommunication terminal is large-sized and the cost is increased. Therefore, heretofore, facsimile transmission directly specifying a destination number from a portable radiocommunication terminal is disabled and for example, facsimile transmission service by a service provider via the service provider (ISP) of the Internet is utilized.
However, in this case, after a user once executes operation for processing for connecting to the service provider of the Internet, he/she is required to execute operation for facsimile transmission and the operation is troublesome.
As it is difficult to provide the function of a printer for outputting the hard copy of receive data to a small-sized portable terminal in case a portable radiocommunication terminal is particularly provided with a function for receiving an electronic mail and a facsimile, receive data is stored in a memory and only a required part is displayed on a display.
If it is expected that mass data is sent, it is desirable that a memory for storing receive data is a mass storage. However, to maintain the portability of a small-sized portable radiocommunication terminal, that is, to prevent a terminal from being large-sized, it is generally difficult to provide a bulk memory. Therefore, heretofore, there is a problem that the quantity of data which a portable radiocommunication terminal can receive is small, plural pieces of receive data cannot be stored in a memory and important receive data cannot be stored. The above problem is particularly remarkable in the case of facsimile data processed as bit map data (dot image data) because the quantity of data is large.
To maintain the miniature, of a portable radiocommunication terminal, a portable radiocommunication terminal is connected to a portable personal computer via a cable and the memory of the personal computer is used for storing receive data. However, in that case, the portable radiocommunication terminal and the portable personal computer are required to be carried simultaneously and it is inconvenient.
As described above, even if a portable radiocommunication terminal and a portable personal computer are connected, for the personal computer, the memory is only utilized for storing receive data and if receive data is processed and displayed, for example, a part of receive data is enlarged or turned and the receive data is displayed, the above enlargement or turning is executed by the application program of a portable radiocommunication terminal and then, the receive data is displayed.
However, there is a problem that if the microcomputer of a portable radiocommunication terminal runs such various application programs, the load of the microcomputer of the portable radiocommunication terminal is incr
