DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The most preferable embodiments of the invention will be explained below referring to the drawings.

FIG. 1 is a system configuration diagram showing an embodiment of a system for incorporating ad information into e-mails according to the invention.

In FIG. 1, each of the terminals T1 such as microcomputers as information retrieval apparatus is connected to a public telephone network N1, which is connected to the internet 1 via an access server AS of a network service provider (NSP).

To the public telephone network N1, a portable terminal T2 such as a PDA (Personal Digital Assistant) and a portable telephone set equipped with the e-mail feature (such as portable telephone sets supporting i-mode feature) is connected via a mobile communications network N2.

An e-mail site S1 is connected to the internet I.

The e-mail site S1 saves e-mails transmitted from a sending terminal T1 or a portable terminal T2 via the internet I together with the destination e-mail addresses, and transmits the saved e-mails to the terminal T1 or portable terminal T2 according to a transmission request made by the receiving terminal T1 or portable terminal T2. As shown in FIG. 2, the e-mail site S1 comprises an e-mail server S1a for supervising transmission/reception of e-mails at the e-mail site S1, an e-mail database S1b for saving e-mails transmitted to the e-mail site S1 together with the destination e-mail addresses, a position information database S1c that stores position information specifying the display range of area information such as a map and traffic facilities by latitude and longitude, and an ad information database S1d that stores ad information specifying an ad and the position of an ad provider (position of the store).

In FIG. 1, S2 represents an area information provision site equipped with a WWW server that provides area information such as a map, traffic facilities and/or an address. S3 represents an area information database site that stores information containing a map and traffic facilities.

FIG. 3 shows an example of position information stored in the position database S1c at the e-mail site S1. FIG. 3 shows position information in hierarchical order on the area around Kamata Station, Ohta-ku, Tokyo.

In FIG. 3, “Level” indicates a layer of position information. Position information on a wide are a is shown from the highest level (Level 1). In the position information, the range of area in each level is represented by latitude and longitude, for example XX° XX″ North Latitude and XX° XX″ East Longitude.

FIG. 4 shows an example of ad information stored in the ad information database at the e-mail site S1. FIG. 4 shows ad data and the latitude and longitude showing the position of the store to be advertised and sales area of articles (hereinafter referred to as the position of an ad provider).

Transmission/Reception of e-mails will be explained referring to FIG. 5 that shows an aspect of e-mails to be transmitted/received and flowcharts in FIGS. 6 and 7 that show procedures for transmitting/receiving e-mails at the e-mail server S1a.

As shown in FIG. 5, the e-mail M contains an e-mail body entry column a and a column b for displaying area information inserted by an e-mail sender.

In the area information display column b, area information such as the map, traffic facilities and/or address of a desired area that the sender of the e-mail M has obtained from the area information provision site and the area information database site S3 via electronic dictionaries and/or the internet (see FIG. 1).

In the following description, the display format for displaying area information in a terminal T1 or a terminal T2 (see FIG. 1) that transmits the e-mail M is assumed to be Format F1 (for example MapFan Format).

FIG. 6 shows the procedure for saving a transmitted e-mail at the e-mail site S1. In FIG. 6, the e-mail server S1a of the e-mail site S1 determines whether the e-mail M has been transmitted from the terminal T1 or terminal T2 or not (step s1). In case affirmative, the e-mail server S1a determines whether the e-mail M displays area information in the display area b or not (step s2).

In case area information is displayed in the display column b of the e-mail M, the e-mail server S1a accesses the position information database S1c and retrieves the position information (latitude and longitude range) corresponding to the area information (for example, a map of Kamata) displayed in the display column b from the position data shown in FIG. 3, then reads the received position information (step s3).

Further, the e-mail server S1a accesses the ad information database S1d and retrieves ad information where a position (latitude and longitude) corresponding to the ad data is contained in the latitude and longitude range indicated by the position information read from the position information database S1c, from the ad information shown in FIG. 4, then reads the retrieved ad information (step s4).

The e-mail server S1a inserts, as a banner ad, the ad data indicated by the ad information read from the ad information database S1d as mentioned earlier into the ad column of the e-mail M mentioned later (step s5), then saves the e-mail where this banner ad is inserted to the e-mail database S1d together with the destination e-mail address (step s6).

FIG. 7 shows the procedure for transmitting an e-mail from the e-mail site S1 to a receiving terminal.

In FIG. 7, the e-mail server S1a determines whether a transmission request has been made by a terminal T1 or a portable terminal T2 (see FIG. 1) (step s10), and in case affirmative, the e-mail server S1a accesses the e-mail database S1b and reads the e-mails corresponding to the e-mail address of the terminal T1 or portable terminal T2 that has made a transmission request (step s11).

Further, the e-mail server S1a detects the display format that can be processed by the terminal T1 or portable terminal T2 that has made a transmission request (steps 12) and determines whether the detected display format differs from the display format (in this example MapFan format) F1 of area information of the e-mail read from the e-mail database S1b or not (step s13)

In case the detected display format differs from the display format of area information of the e-mail read from the e-mail database S1b, the e-mail server S1a converts the display format F1 of area information of the e-mail to the display format F2 (for example Mapion format) (step S14), then transmits the e-mail M1 to the terminal T1 or portable terminal T2 that has made a transmission request (step s15).

In case the display format of area information is the same, the e-mail server S1a transmits the e-mail M2 as it is to the terminal T1 or portable terminal T2 that has made a transmission request (step s15).

Conversion of the display format of the area information is possible via a variety of known systems.

As mentioned earlier, as shown in FIG. 5, to the terminal T1 or portable terminal T2 that has made a transmission request, is transmitted an e-mail T1 or T2 where ad data related to area information such as a map, traffic facilities and/or an address displayed in the display column b is inserted in the ad column c and the display format of the area information displayed n the display column b conforms to the display format of area information in the terminal T1 or portable terminal T2 that has made a transmission request.

A receiving party that has received an e-mail M1 or M2 where ad data related to area information is inserted as mentioned earlier can obtain ad data related to the area as well as the area information, thus upgrading the convenience of utilizing the area information.

Further, an ad provider can automatically provide with the user with ad information having high utility value. This encourages the use of an e-mail as an ad medium.

While ad data is inserted into an e-mail M as an banner ad in the aforementioned example, ad data may be inserted into a page separate from the e-mail body so that it is displayed on the entire screen of a receiving terminal or ad data may be inserted as an attached file.

While ad data is inserted into an e-mail M when the e-mail M is saved into the e-mail database S1b of the e-mail M at the e-mail site S1 in the aforementioned example, by which procedure the e-mail site S1 can promptly transmit the saved e-mail M to a receiving terminal when said receiving terminal has made an access to the e-mail site S1, ad data may be inserted into the e-mail M when the e-mail M is read from the e-mail database S1b for transmission to a receiving terminal.

While an e-mail transmitted from a sending terminal is once saved in the e-mail database S1b in the aforementioned example, ad data may be inserted the same way in case the e-mail is not saved in the e-mail database S1b but transmitted to a destination e-mail server.

While conversion of the display format of area information is made by detecting the display format of a receiving terminal that has accessed the e-mail site S1 in the aforementioned example, information for identifying the display format of a receiving terminal may be inserted into an e-mail M at a sending terminal and the e-mail site S1 may convert the display format of area information based on the identification information inserted into this e-mail M.

In this case, the transmitted e-mail M may be saved into the e-mail database S1b with the display format of the area information converted beforehand to a format conforming to the display format of a sending terminal at the e-mail site S1 so that the e-mail site S1 can promptly transmit the saved e-mail M to a receiving terminal promptly when the receiving terminal has made an access to the e-mail site S1.
