Further, according to the mobile communication system of the present invention, a user information database is provided in the advertisement server, the number of times the advertisement is viewed is totaled for each user, and this information is stored in the user information database. When providing a communication service that collects communication charges, the user's communication charges are discounted or the content distributed for a fee is free of charge according to the number of times the advertisement is viewed stored in the user information database. It can also be manipulated to make it available.

【0051】

As described above, according to the mobile communication system of the present invention, an information storage device that stores advertisement information and an information storage device control unit that selectively controls desired advertisement information from the information storage device are APs (base stations). Built into. Then, when the MT (mobile terminal) starts communication, the advertisement information stored in the information storage device is selected by the user data processing unit, and the selected advertisement information is added to the communication information. Further, the address of the MT of the transmission destination is added by the second header identification / processing unit, the wireless transmission / reception unit performs predetermined modulation processing, and the transmission is performed from the antenna. As a result, when the MT starts communication, the desired advertisement information is displayed on the display unit of the MT.

【0052】

In addition, the AP is installed and managed by advertisers such as corporations, individuals, and advertising agencies, and the advertising information of the information storage device built into the AP can be updated by the advertiser at any time. Further, when the advertiser provides an advertising server, the advertising information of the information storage device built in all the APs managed by the advertiser can be changed or updated at once. Alternatively, the advertising information of the information storage device built in each AP managed by the advertiser can be individually changed or updated. On the other hand, the MT owned by the user is provided with an advertisement display space, and the advertisement information from the AP is displayed in this advertisement space before the start of communication or during communication.

【0053】

Also, if you select and click the banner in the advertising information displayed in the advertising space of MT, detailed advertising content will be displayed in that advertising space. Therefore, the MT user can view the detailed advertisement content, while the information that the detailed advertisement content has been viewed is transmitted to the AP. As a result, the user data processing unit of the AP can also allow the user's MT to connect to the Internet on the condition that the detailed advertisement information is viewed.

【0054】

The embodiments described above are examples for explaining the present invention, and the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the gist of the invention. For example, even if the structure does not have an advertisement space provided in advance inside or outside the display unit as shown in FIGS. 23 to 25, the advertisement information and the communication information can be displayed arbitrarily by pressing a predetermined button. The structure may be switchable.

[Effect of the invention]

As described above, according to the mobile communication system of the present invention, an information storage device is built in an AP (base station), and an advertisement server provides a large amount of advertisements by providing advertisement information from the AP to a mobile terminal. Eliminates the need to retain information. In addition, it is not necessary to deliver the advertisement information from the advertisement server to the mobile terminal every time. Therefore, the load on the advertising server and the Internet can be reduced, and the resources that should originally be communicated on the Internet can be effectively utilized.

【0056】

Further, instead of the advertiser monopolizing the advertisement information stored in the information storage device built in the AP, the advertiser installs and manages the AP, so that the cost burden of the entire communication system can be widely distributed. .. Therefore, the capital required for the telecommunications business of the telecommunications service provider can be reduced, which can be useful for the further spread of the telecommunications infrastructure. Furthermore, since various corporations install many APs for advertising purposes, the burden of mobile terminal usage fees on users can be further reduced.

【0057】

In addition, since corporations and individuals who install APs can provide advertisement information related to the place where APs are installed to users of mobile terminals, more effective advertisement distribution can be expected according to TPO. Furthermore, the cost of communication infrastructure is distributed to corporations and individuals who install APs, and these corporations and individuals open the use of APs to users free of charge for the purpose of advertising effectiveness, which is necessary for billing call charges. No need for a new infrastructure system, and a cheaper communication infrastructure can be constructed.

【0058】

Further, according to the mobile communication system of the present invention, it is possible to provide community-based advertising information and to provide a wide range of advertising information. Furthermore, the advertisement information stored in the information storage device provided in each AP can be arbitrarily changed or updated from a remote location. In addition, since the information storage device is not an additional device to the existing mobile base station, an advertising agency or the like purchases a large number of APs and installs them on a street corner, etc., and the information storage device of the predetermined AP is requested by the advertiser. Only can be changed or updated to provide detailed advertising information to MT users. Further, the advertising agency owns an advertising server, and all APs under the control of the advertising agency can be controlled by the above-mentioned advertising server. In addition, since the advertising agency can maintain the AP by the advertising revenue from the advertiser, it is possible to provide a cheaper communication service to the MT connected to the general subscriber line.
