Technique of providing information to mobile devices
First Claim
1. An access point that provides a connecting point used for connecting a plurality of clients with a wide area network, said access point comprising:
- a wireless communication module that transmits information to and from at least one client among said plurality of clients by radio wave;
an announcement information storage module that stores announcement information, which is recognizable by said one client;
a status detection module that detects at least a position of said one client, based on a receiving status of the radio wave from said one client, said status detection module further including sub-module that detects an attitude of said one client, in addition to the position of said one client;
a position specification module that specifies a positional relationship between the position of said one client detected by said status detection module and a position of another client connecting with said access point, said position specification module determining that said one client and said another client hold a predetermined positional relationship, when it is specified that said one client and said another client face each other based on the position and the attitude of said one client and the position of said another client; and
an information transmission module that transmits the announcement information stored in said announcement information storage module to said one client, when said position specification module determines that said one client and said another client hold the predetermined positional relationship.

Abstract
The access point of the present invention saves power consumption and attains size reduction of a mobile device that receives information. A radio base station 10a provides a connecting point for connecting a plurality of clients with the Internet 60, and stores announcement information, which is recognizable by a user terminal 20a. The user terminal 20a transmits information to and from an outlet terminal 25 by radio wave. The radio base station 10a detects the position of the user terminal 20a and the position of the outlet terminal 25, based on the receiving status of the radio wave from the user terminal 20a and the outlet terminal 25. The radio base station 10a provides the user terminal 20a with the stored announcement information when the user terminal 20a comes close to the outlet terminal 25 to be within a preset distance from the outlet terminal 25.

7. A method of connecting a plurality of clients with a wide area network via an access point, said method comprising the steps of
storing announcement information, which is recognizable by said plurality of clients; -
transmitting information to and from at least one client among said plurality of clients by radio wave; detecting at least a position and an attitude of said one client, based on a receiving status of the radio wave from said one client; specifying a positional relationship between the detected position of said one client and a position of another client connecting with said access point, including determining that said one client and said another client hold a predetermined positional relationship, when it is specified that said one client and said another client face each other based on the position and the attitude of said one client and the position of said another client; and transmitting the stored announcement information to said one client, when it is determined that said one client and said another client hold a predetermined positional relationship.
