Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information distribution system using a portable information terminal.

[0002]

2. Description of the Related Art As a service using an information distribution system, information transmitted wirelessly from an information distribution server installed in a town is generally automatically obtained by simply carrying around a portable information terminal. In some cases, the information is received and stored, and the user can view the information when he / she likes.

[0003] First, however, there is a problem that when a user passes near an information distribution server, sufficient distribution may not be possible within a limited time until the user goes out of a radio reach. Secondly, when many users pass near the information distribution server at once, there is a problem that the information distribution server cannot cope with a large number of portable information terminals, so that distribution may not be in time.

[0004] As a solution to the first problem, there is a solution for preventing a user from passing by, but restricting a user's action for information distribution is not good in terms of usability.
In addition, it is possible to install the information distribution server in a place where the user is likely to stop, but the place where the information distribution server can be installed is considerably limited. One solution is to extend the time that can be distributed by increasing the range of wireless communication. However, increasing the range of wireless communication leads to an increase in power consumption, and is not suitable for a mobile device such as a portable information terminal that relies on battery power.

[0005] One of the solutions is to shorten the time required for distribution by increasing the communication speed. However, this case is not suitable for a mobile device such as a portable information terminal having a limited processing capability.

As a solution to the second problem, a method of solving the problem by broadcasting distribution information is generally used.
In this method, since there is no way for the receiving side to know whether the information has been safely received, the distribution information may be missing, and there is a problem that the distribution cannot be performed reliably. There is also a method of storing and managing the information received on the receiving side, but also in this case, it is not suitable for a mobile device such as a portable information terminal having a limited processing capacity, and the information is transmitted to the information distribution server in advance. There was a problem that the time required for distribution increased due to the need to communicate.

[0007] Japanese Patent Application Laid-Open No. Hei 18-18523 discloses that a user has a portable storage medium and an information terminal, and uses an automatic ticket gate to distribute information desired by the user without troublesome operation. It describes an information distribution system that can do this.
In this information distribution system, an information distribution server is provided in an automatic ticket gate of a station, and when a portable storage medium such as a commuter pass used by a user is passed through the automatic ticket gate, the server is stored in the portable storage medium. This technique reads contract data, acquires information to be distributed, and distributes only valid information from an information distribution server to a portable information terminal of a user.

[0008] If this technique is used, unnecessary information is not distributed, so that the time required for distribution can be reduced. Also, if information indicating how much information has been received is left in the portable storage medium, information that has not been received at the next use can be acquired, so that information omission can be prevented. However, in this technology, it is necessary to carry both a portable information terminal and a portable storage medium such as a commuter pass. There is a problem that the delivery service cannot be received even if the terminal is provided.

Further, since a device for reading information from a portable storage medium is required, this system can be introduced only in a very limited place such as an automatic ticket gate. Further, unless the user passes through an automatic ticket gate, the user cannot receive the information distribution service even in an area where radio waves can reach. The present invention has been made in view of the above circumstances, and an information distribution facility for distributing information,
An object of the present invention is to provide an information distribution system capable of distributing valid information with an information receiving device that receives information and shortening a distribution time.
