For this reason, it is possible to automatically obtain landmark content information (or a link to the content) in accordance with the current situation of the user automatically in real time without searching for the content.

  Hereinafter, the present invention will be described in preferred embodiments with reference to the drawings. In the following, the description will mainly be given on the assumption that the mobile communication terminal is a mobile phone. Any other portable terminal (PHS, PDA, node personal computer, etc.) may be used.

  FIG. 1 is a diagram showing an outline of a system configuration which is a preferred embodiment of the present invention. In this embodiment, the mobile communication terminal 1 receives radio waves for position detection from a plurality of GPS satellites 2. In this figure, only one GPS satellite 2 is shown, but as is well known, it is necessary to receive radio waves from at least three, usually four or more GPS satellites 2, in order to specify the position. There is. The radio wave transmitted from the GPS satellite 2 includes various orbit information and very accurate time data by an atomic clock. In order to obtain easy-to-handle position data such as the latitude and longitude of the current position from these information, the mobile communication terminal 1 holds the orbit information of the GPS satellite 2 and the additional information obtained from the nearest base station 3 to perform complicated positioning. It is necessary to perform an operation. Therefore, the position data acquisition server 6 normally connected via the public communication network 4 performs these positioning calculations, and uses the obtained results as position data (latitude, longitude, altitude if possible, etc.). 1 is used. If the mobile communication terminal 1 is equipped with a positioning calculation function, it is also possible to directly acquire position data without communicating with the position data acquisition server 6.

  The mobile communication terminal 1 transmits its own position data such as latitude and longitude obtained in this manner to the service provider's Web server 7. The Web server 7 holds means (Web page DB 7a, etc.) for generating a screen for providing services and advertisements on a homepage or portal site, and this position is stored in the position data / content server 8 connected to the Web server 7 on the network. Request content (or links to it) based on data. Upon receiving this request, the location data / content server 8 searches a database (landmark information DB 8a or the like) stored inside the server or an external content server 9 (including the content DB 9a) to search for the location of the mobile communication terminal 1. Find a “landmark” near the location indicated in the data. In general, “landmark” refers to a building or monument that is a symbol of the land (Kojien 5th edition), but here it is used in a broader sense and can be a landmark or target in a specific place. It refers to a building, facility, store, etc., whose contents and location data of the location are publicly available on the network and can be used.

  The position data / content server 8 includes a landmark information DB 8a in which position data of a number of registered landmarks are recorded. Alternatively, the position data / content server 8 obtains landmark position data from an external content server and stores the landmark information DB 8a. You may make it update regularly.

  In addition, in the landmark information DB 8a of the position data / content server 8, in order to be able to change the landmark displayed on the mobile communication terminal 1 according to the time zone, the landmark time zone as shown in FIG. A time zone priority table having display priorities is provided. This display priority may be obtained by statistical means or experience, but it is more desirable that the system administrator or user can set or change in advance.

  The position data / content server 8 may be a single server or a plurality of servers, or may be included in the Web server 7.

  FIG. 2 is a diagram showing an outline of the flow of processing in the system according to a preferred embodiment of the present invention. The mobile communication terminal 1 possessed by the user periodically transmits a position data request to the position data acquisition server 6 in order to acquire its own position data. Of course, it is also possible to explicitly send a position data request by a user operation. If the mobile communication terminal 1 is equipped with a positioning calculation function, it is also possible to directly acquire position data without communicating with the position data acquisition server 6.

  When the position data acquisition server 6 receives the position data request from the mobile communication terminal 1, the position data acquisition server 6 performs positioning calculation using the GPS reception information included in the position data request, and the position data (longitude, latitude, if possible) Altitude). The obtained position data is transmitted to the mobile communication terminal 1.

  Next, when the mobile communication terminal 1 acquires its own position data, it transmits the position data (longitude, latitude, etc.) to the service provider's Web server 7. Upon receiving this position data, the Web server 7 transmits a content request regarding a nearby landmark to the position data / content server 8 based on information such as longitude and latitude included therein.

  The location data / content server 8 returns a search result of content suitable for the location to the Web server 7 using a database including landmark location data. The Web server 7 generates an optimal search result and an optimal screen (such as a portal site top page) for the location, and transmits the generated search result to the mobile communication terminal 1.

  FIG. 3 is a diagram showing details of a processing flow in the above-described system according to a preferred embodiment of the present invention. First, the mobile communication terminal 1 transmits a positioning information request (position data request) to the position data acquisition server 6 periodically or by a user operation. This positioning information request includes GPS satellite information ("Almanac" which is rough orbit information of all GPS satellites and "Ephemeris" which is accurate orbit information of the GPS satellite itself) in this positioning information request Information on peripheral reference stations (stations serving as a reference among peripheral base stations) may be included.

  The position data acquisition server 6 performs a positioning calculation based on the received information (step S10), and returns a positioning result (data such as longitude, latitude, altitude, reliability, etc. can also be acquired). Alternatively, although not shown, the position data acquisition server 6 does not perform the positioning calculation, and the mobile communication terminal 1 easily performs the positioning calculation using information from the nearest base station in order to facilitate the positioning calculation. The “assist data” to be transmitted may be transmitted to the mobile communication terminal 1, and the mobile communication terminal 1 may perform the positioning calculation.

  The mobile communication terminal 1 generates terminal information including the positioning result (position data) obtained in this way, the terminal ID, and the like (step S11), and transmits it to the Web server 7. The Web server 7 specifies the terminal ID (step S12) and stores it. Then, a content request based on the terminal position data is transmitted to the position data / content server 8.

  The position data / content server 8 searches for nearby landmarks specified by the position data, and also searches for information on the contents of the landmarks (step S13). The obtained content search result (usually the link destination of the content) is returned to the Web server 7, and the Web server 7 generates a screen optimal for the location (step S14). Specifically, a list of nearby landmarks is posted together with link information on the top page of the service provider's portal site. This list may be replaced with information (such as news) normally displayed at the top in order to minimize the user's scrolling effort. In order to dynamically change the Web page in this way, a known technique such as Ajax (Asynchronous JavaScript and XML) may be used. For the convenience of the user, the order in which landmarks are displayed can be changed dynamically according to the time zone and other information. This will be described later.

  FIG. 4 is an example of a time zone priority table used by the position data / content server 8 for searching for contents related to landmarks. This table includes latitude and longitude (altitude data if possible) as position data for each landmark. Further, a display priority parameter can be included as the time zone priority in order to change the display order for each time zone of the day. For example, in the example of FIG. 4, landmarks of commuting means such as a station are preferentially displayed in the time zone of 6 to 8 o'clock on weekdays. For simplicity, these parameters are shown as integers in FIG. 4, but are not necessarily integers. Also, restaurants such as restaurants are displayed at the top in the time zone from 10 to 12 o'clock and 18 to 20 o'clock, and transportation such as a station is again displayed at the top in the time zone from 22 to 24 o'clock. A display priority parameter can be set. Such parameters may be determined empirically using statistical information, but various parameters such as day of the week, holidays, seasons, weather, and landmark attributes (eg, transportation, restaurants, halls, tourist facilities) It is desirable to update the data daily in consideration of the data. In addition, when there are a plurality of landmarks such as stations and other conditions are the same, they may be displayed in order from the closest to the current position.

  Furthermore, the display order may be adjusted or changed depending on the distance from the current position as well as the date and time. Further, not only the content of the landmark itself but also other related information (landmark related information or accompanying information) may be displayed.

  For example, as shown in FIG. 5, when the landmark closest to the current position is a station, the top page of the portal site includes not only information such as the timetable of the station, but also a route search menu, transfer time, fare You may make it display the link to the web page which displays. In addition, as shown in FIG. 6, for example, when the landmark closest to the current position is a restaurant, the coupon of the searched restaurant is displayed in the advertisement field of the “search result page” on the top page of the portal site. It is possible to display advertisements. In addition, a link to a reservation service such as a restaurant may be added. Further, a learning function can be provided by recording frequently displayed pages in the storage unit of the mobile communication terminal 1. Thus, the convenience for the user can be improved by combining the landmarks and information according to the characteristics and displaying the information for the user.

  FIG. 7 is an example of a flowchart for determining the order in which the landmarks optimal for the current position are displayed. First, the position data / content server 8 searches for landmarks within a predetermined distance (step S20). Specifically, the landmark information DB 8a is searched and, for example, a landmark within a radius R from the current position is extracted. When such a landmark is not found (step S21: No), that fact is transmitted to the request source and the process is terminated. When one or more landmarks are found (step S21: Yes), the current time is compared with the time when the mobile communication terminal 1 acquires the position, and it is checked whether it is within a predetermined range (step S22). If it is not within the predetermined range, a retransmission request for position data is transmitted (step S23). This is because if the time when the position data is acquired for some reason and the time when the position data / content server 8 acquires the content are significantly different (if the time exceeds the predetermined range), the user is already far from the position. This is because there is a possibility that information useful for the user may not be obtained. Of course, instead of issuing such a retransmission request, the current time and the time at which the position data was acquired may be displayed side by side simply for confirmation.

  Next, when a plurality of landmarks are detected, the position data / content server 8 first sorts in order of distance from the current position of the user (step S24). Then, the priority of the time zone corresponding to the current time is acquired from the time zone priority table (see FIG. 4) (step S25), this is weighted with a predetermined parameter, and this value and the distance of the landmark are integrated. The display order is adjusted (step S26). For example, if the distance between a certain landmark A and the current position is 100 m, the time zone priority parameter is 2, the distance between another landmark B and the current position is 120 m, and the time zone priority parameter is 1, The display order of the mark A is 100 × 2 = 200, and the display order of the landmark B is 120 × 1 = 120. Therefore, the landmark B can be displayed at the upper position even if the distance is longer than the landmark A. In practice, various parameters other than the time zone priority can be considered to determine the display order, but these are determined and accumulated sequentially along with their weighting parameters according to statistical means or empirical rules. To do.

In general, if the distance between landmarks is d ₀ and other parameters are P _i , the priority order for displaying the landmarks is a ₀ * d ₀ + a ₁ * p ₁ + a ₂ * p ₃ +. It can be obtained by a linear combination function. Here, a _i (i = 0, 1,..., N) is a weighting factor for prioritizing the parameters P _i .

  Finally, the position data / content server 8 transmits the landmark display order determined in this way and the landmark content information to the Web server 7 (step S27). Since the Web server 7 stores the ID of the mobile communication terminal, it is possible to generate a screen that matches the position data of the mobile communication terminal or to change the screen configuration of a standard portal site.

  FIG. 8 is a diagram showing an example of the top page of the portal site of the service provider for mobile phones. As in the example of this figure, on the top page of the portal site, the service provider's logo area 10, the advertisement area 11, the search area 12, etc. are usually displayed at the top, and the frequently used, for example, news area 13 and content store area 14 are sequentially displayed. Normally, this screen configuration is determined according to the frequency of use or importance so as to minimize the user's scrolling operation due to the limitation of the screen size of the mobile phone.

  The user wants to avoid as much as possible the troublesome scrolling operation or obtaining the desired information from a deep position in the menu hierarchy when viewing the display of the mobile phone while traveling outside the city or the like. However, there are cases in which it is desired to obtain information about the target landmark during such movement. For example, when the last train time is worried, such as when going home late at night in an urban area, or when you find a landmark that you are worried about while riding a vehicle in a sightseeing spot. Therefore, the landmark information based on the position information targeted by the present invention is desirably displayed on the top page of the portal site. This is because the target information may change every moment according to the time and the current position, and must be displayed as easily as possible. Information such as news changes one after another, but does not change every moment depending on where the user is. For this reason, it is desirable that the landmark information based on the position information is displayed quite high (above news etc.) in the top page. It is further desirable to provide means for turning off the landmark display (for example, by setting an initial screen of the page, a customization function, or a predetermined button operation).

  FIG. 9 is a diagram showing a first modification example from the standard screen of the top page of the portal site for mobile phones. In general, a portal site is commonly configured for all users by a service provider, but in a preferred embodiment of the present invention, the portal site is personalized for a user who receives this location information service. The screen configuration. As shown in the figure, in this example, the neighboring landmark information 15 is displayed higher than news. For example, when the current position is near the terminal station and the current time is 23:00, the last train time of each route and the last flight time of the bus stop are displayed at the top. Further, the neighboring landmark information may always display a link to a surrounding map based on the current position.

  FIG. 10 is a diagram showing a second modification example from the standard screen of the top page of the portal site for mobile phones. In this example, it is assumed that the user is displaying the portal site at 12:00 in the downtown area. In this case, restaurants such as restaurants, department stores, movie theaters, etc. can be displayed at the top. Since stores such as restaurants are often located on different floors of the same building, it is desirable to store altitude data in addition to latitude and longitude in the database. By adding altitude information, it is possible to distinguish stores in the same building.

  FIG. 11 is a diagram showing a third modification example from the standard screen of the top page of the portal site for mobile phones. In this example, a portal site is displayed at 10:00 in a sightseeing spot. Here, the arrival and departure times of sightseeing buses and ferries are displayed at the top with reference to the characteristic information of the sightseeing spots. In addition, sightseeing spots such as amusement parks and accommodation information such as hotels and inns are also displayed. In a sightseeing spot, it is more desirable to adjust the display order in consideration of not only the distance from the landmark and the current time but also the weather and season. As described above, by using the system and the method according to the embodiment of the present invention, it is possible to display finely the data related to the position information of the user.

  FIG. 12 is a diagram showing an example of the hardware configuration of the server apparatus 100 as an example of the hardware configuration of the Web server 7 and the position data / content server 8 described in FIG.
