However, the present invention is not limited to the following embodiments. In addition, for clarity of explanation, the following description and drawings are simplified as appropriate.

<Embodiment 1>
Embodiment 1 of an advertisement distribution system and an advertisement distribution method according to the present invention will be described with reference to FIGS.

  First, the advertisement distribution system of this embodiment will be described. This advertisement distribution system includes a mobile terminal 1, a Home Location Register (HLR) 2, a Serving GPRS Support Node (SGSN) / Mobile Switching Center (MSC) 3, a profile server 4, a database (DB) 5, an advertisement content server 6, an advertisement A distribution server 7, a mail distribution server 8, and a network 9 are provided. Further, although not shown in the figure, a radio base station, a radio network control device, a relay packet switch, and the like are also provided as in a normal mobile communication system.

  The mobile terminal 1 is a mobile phone or a PDA (Personal Digital Assistant). The mobile terminal 1 is installed with an agent that analyzes a mail received or transmitted by the mobile terminal 1 and creates a user preference profile. That is, the agent uses the keyword used in the title or body of the email received or transmitted by the mobile terminal 1, and counts the number of appearances of this keyword. And the user's current preference profile. Since the user's preference profile is created by analyzing the mail received or transmitted by the user, the user's preference profile can be easily created and updated.

  The user's preference profile may be created and updated for each email, or may be created and updated for each set number of emails.

  The mobile terminal 1 transmits the created preference profile to the profile server 4. At this time, the mobile terminal 1 may transmit all of the created preference profiles to the profile server 4 or may transmit only the changed preference profile (that is, a part of the preference profile) to the profile server 4. good.

  The radio base station, radio network control device, HLR2, SGSN / MSC3, relay packet switch, mail distribution server 8, and network 9 have substantially the same configuration as that of a typical mobile communication system, and thus description thereof is omitted. Here, it is preferable that the HLR 2 includes an item that uses an advertisement distribution system as subscriber data. Since the user can register to use the advertisement distribution system, the advertisement can be distributed to a person who does not want to distribute the advertisement, and the deterioration of the impression of the advertiser can be reduced.

  The profile server 4 is means for receiving and storing all or part of the user's preference profile created by the agent of the mobile terminal 1. When the agent of the mobile terminal 1 newly creates a user preference profile, the profile server 4 updates the old preference profile to a new preference profile. Therefore, the profile server 4 always stores the user's current preference profile.

  The database 5 is a means for storing advertisement information. As shown in FIG. 2, the advertisement information here is associated with the location information and the advertiser's industry keyword, and the industry keyword is associated with the industry-related keyword and the advertiser's company name. .

  Therefore, it is preferable that the database 5 includes a thesaurus for converging from the user's preference profile to the business category keyword of the advertiser. A thesaurus classifies words according to the relationship between synonyms and similar words. Referring to FIG. 2, for example, it is assumed that the keyword “pasta” is obtained as the user's preference profile. When the keyword “pasta” does not exist on the database 5, a word existing as a keyword on the database 5 is selected from synonyms of “pasta” with reference to the thesaurus. Thereafter, the database 5 is referred to again using the keywords obtained from the thesaurus. In this example, a keyword can be selected from the database 5 if “Italian cuisine” is set as a synonym for “pasta”. Thus, even when there are no keywords on the database 5, it is possible to converge to the keywords set in the database 5 by using the thesaurus. Note that a plurality of databases 5 are preferably provided for each piece of position information.

  The advertisement distribution server 7 is means for transmitting an advertisement to the mobile terminal 1 via the network 9. This advertisement distribution server 7 refers to the advertisement information in the database 5 and is suitable for the current position and preference of the user based on the position information from the mobile terminal 1 and the user's preference profile received from the profile server 4. Determine the advertisement. Thereafter, the advertisement distribution server 7 acquires the advertisement content from the advertisement content server 6 that manages the advertisement content, and transmits it to the mobile terminal 1 via the network 9. Since the advertisement distribution server 7 determines the advertisement based on the current position of the user and the new preference profile, the advertisement suitable for the current position and preference of the user can be transmitted to the mobile terminal 1.

  The location information of the mobile terminal 1 is acquired based on RA (Routing Area) and LA (Location Area) which are location information managed by the SGSN / MSC 3, and the SGSN / MSC 3 is connected to the advertisement distribution server 7. 1 position information is transmitted. Thereby, the advertisement delivery server 7 can always obtain the position information of the new mobile terminal 1.

  Next, the advertisement distribution method of the present embodiment will be described along the sequence diagram shown in FIG.

  First, the user installs an agent on the mobile terminal 1. When installing the agent, the mobile terminal 1 acquires the URL of the profile server 4. Thereafter, the mobile terminal 1 uses the advertisement distribution system and transmits the URL of the profile server 4 to the HLR 2 (S100).

  When the agent of the mobile terminal 1 creates a user preference profile, the mobile terminal 1 transmits the user preference profile to the URL of the profile server 4 acquired when the agent is installed (S200). Further, the agent of the portable terminal 1 sequentially creates user preference profiles and the portable terminal 1 continues to transmit to the profile server 4, and the profile server 4 continues to update the user preference profile (S300). That is, the process in which the profile server 4 continues to receive and update the user's preference profile is not limited to the illustrated example, but is performed intermittently or intermittently.

  The HLR 2 stores subscriber data of the user of the mobile terminal 1 in advance. The subscriber data includes the use of the advertisement distribution system, the URL of the profile server 4 and the location registration area of the mobile terminal 1. This subscriber data is copied from the HLR 2 to the SGSN / MSC 3 (S400).

  The advertisement distribution server 7 requests the location information of the mobile terminal 1 from the SGSN / MSC 3. The SGSN / MSC 3 sequentially determines the current position of the user from the position information acquired from the mobile terminal 1 and transmits the subscriber data of the user and the position information of the mobile terminal 1 to the advertisement distribution server 7 (S500). The timing at which the advertisement distribution server 7 requests the location information of the mobile terminal 1 from the SGSN / MSC 3 is intermittently or intermittently performed.

  When the advertisement distribution server 7 receives the subscriber data of the user and the location information of the mobile terminal 1 from the SGSN / MSC 3, the advertisement distribution server 7 requests the profile server 4 for the user's preference profile. The profile server 4 transmits the user's preference profile to the advertisement distribution server 7 (S600). As described above, the profile server 4 continuously receives and updates user preference profiles from the portable terminal 1.

  The advertisement distribution server 7 requests advertisement information from the database 5. The database 5 transmits the advertisement information to the advertisement distribution server 7 (S700). The advertisement distribution server 7 refers to the received advertisement information, and determines an advertisement suitable for the current position and preference of the user based on the position information of the mobile terminal 1 and the user's preference profile. For example, as shown in FIG. 2, the advertisement information in the database 5 has “Omotesando”, “Shibuya”, and “Hakone” as position information, and keywords related to the type of business of the advertiser. "Italian cuisine", "fast food", and "hot spring" are set. When the user's location information is Omotesando and the keyword representing the preference is “Italian cuisine” based on the user's preference profile, there are a plurality of company names that wish to send advertisements for Italian cuisine. Here, there are three Italian restaurants A, B, and C. Which Italian restaurant is to be transmitted from the Italian restaurants A, B and C depends on the probability. In this example, since Italian restaurant A has the highest probability, Italian restaurant A is likely to be transmitted. This probability can be set artificially by an administrator who manages the database 5.

  The advertisement distribution server 7 refers to the advertisement content server 6 based on the determined advertisement and requests the advertisement content server 6 for the advertisement content. Then, the advertisement content server 6 transmits the advertisement content to the advertisement distribution server 7 (S800).

  The advertisement distribution server 7 uses the subscriber data acquired from the SGSN / MSC 3 to transmit the received advertisement content to the mobile terminal 1 via the network 9 (S900). The advertisement distribution method described above analyzes the mail received or transmitted by the mobile terminal and creates the user's preference profile. Therefore, the user's preference profile can be easily created and updated. Moreover, since the advertisement transmitted to the portable terminal 1 is determined based on the user's constantly updated preference profile and the position information of the portable terminal 1, an advertisement suitable for the user's current position and preference is given to the portable terminal. Can be sent.

<Embodiment 2>
In the above-described embodiment, the agent is installed in the mobile terminal 1, but this is not a limitation. Even if an agent is installed in the mail delivery server 8, it can be implemented in substantially the same manner.

  In this case, the mail distribution server 8 analyzes the mail received or transmitted via the mail distribution server 8 and creates a user preference profile. Also in the advertisement distribution system and the advertisement distribution method of the present embodiment, the user's preference profile can be easily created and updated because the user's preference profile is created by analyzing the mail received or transmitted by the mobile terminal. Moreover, since the advertisement transmitted to the portable terminal 1 is determined based on the user's constantly updated preference profile and the position information of the portable terminal 1, an advertisement suitable for the user's current position and preference is given to the portable terminal. Can be sent.

<Embodiment 3>
In the embodiment described above, the advertisement distribution server 7 requests the location information of the mobile terminal from the SGSN / MSC 3, and the SGSN / MSC 3 transmits the location information of the mobile terminal 1 in response to the request from the advertisement delivery server 7. However, this is not the case.

  The SGSN / MSC 3 transmits the location information of the mobile terminal 1 to the HLR 2, and the advertisement distribution server 7 periodically inquires of the HLR 2 whether the location information of the mobile terminal 1 has changed, and the SGSN / MSC 3 has changed. It is good also as a structure received from HLR2.
