  An example of a preferred embodiment according to the present invention will be described below based on the drawings.

[System Overview]
FIG. 1 is a diagram showing a configuration of a computer system that implements a method according to an example of a preferred embodiment of the present invention.

  The mobile communication terminal 10 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 pieces of information, the mobile communication terminal 10 holds orbit information of the GPS satellite 2 and additional information obtained from the nearest base station 3 to perform complicated positioning. It is necessary to perform an operation. For this reason, the position information acquisition server 20 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.). 10 is used.

  The mobile communication terminal 10 transmits its own position data such as latitude and longitude obtained in this way to the web server 30 of the service provider. The position information database server 40 holds means (position information DB 40 a and the like) for storing position data together with time data, and stores position data received from the Web server 30.

  The Web server 30 holds means (Web page DB 30a and the like) for generating a screen for providing services and advertisements on a home page or portal site, and stores position data or the like in a content server 50 connected to the Web server 30 on the network 5. Request based content (or its link). Upon receiving this request, the content server 50 searches a database (content DB 50 a or the like) stored inside the server or an external server, and is connected via the mobile communication terminal 10, the public communication network 4, or the base station 3. Content data to be transmitted to the communication terminal 15 is extracted.

  In the above configuration, a system in which a plurality of servers are arranged is used. However, the configuration is not limited to this, and can be freely integrated or divided for each function. The following embodiment will be described based on the server configuration shown in FIG. 1, but can be appropriately read depending on the difference in the server configuration.

  FIG. 2 is a diagram showing an outline of a processing flow in the system according to an example of the preferred embodiment of the present invention.

  The mobile communication terminal 10 possessed by the user periodically transmits a position data request to the position information acquisition server 20 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 10 is equipped with a positioning calculation function, it is possible to directly acquire position data without communicating with the position information acquisition server 20.

  When receiving the position data request from the mobile communication terminal 10, the position information acquisition server 20 performs positioning calculation using the GPS reception information included in the position data request, and the position data (longitude, latitude, if possible) Altitude). In addition, similar results can be obtained using other techniques, such as calculating position data using electric field strengths of a plurality of base stations and antennas. The obtained position data is transmitted to the mobile communication terminal 10.

  Next, when the mobile communication terminal 10 acquires its own location data, the mobile communication terminal 10 transmits time data and identification data for identifying the mobile communication terminal 10 together with the acquired location data to the Web server 30 of the service provider. Here, the time data may be acquired from the position information acquisition server 20, or may be measured by the mobile communication terminal 10. The mobile communication terminal 10 can also acquire time data from a GPS satellite.

  Here, the Web server 30 transmits a request for content related to the obtained position data and moving means to the content server 50. The content server 50 returns a search result of content (additional information) suitable for the position and moving means to the Web server 30.

  Then, the Web server 30 shapes the acquired data of various contents, generates screen data to be displayed on the mobile communication terminal 10, and transmits the screen data. Here, the transmission destination is not limited to the mobile communication terminal 10, and information related to the mobile communication terminal 10 may be transmitted to the communication terminal 15 in response to a request from another communication terminal 15 or automatically.

  As described above with reference to FIGS. 2 and 3, in the present embodiment, the position information database server 40 stores the position data regarding the mobile communication terminal 10, but the configuration is not limited thereto.

Connect to. The same applies to the communication terminal 15.

[Moving means estimation processing]
FIG. 4 is a diagram showing a flow of moving means estimation processing according to an example of the preferred embodiment of the present invention.

  In step S <b> 105, the Web server 30 receives position data, time data, and terminal identification data from the mobile communication terminal 10. Here, the identification data may identify the mobile communication terminal 10 or may identify the user of the mobile communication terminal 10. In the case of data for identifying a user, the user can be specified by the same identification data even if the mobile communication terminal 10 is changed by, for example, replacement.

  In step S110, the position information database server 40 stores the position data received by the Web server 30 and the like. Specifically, for example, the user identification data, time data, and position data (latitude, longitude, and altitude if possible) are stored using the position information table 60 shown in FIG. Thereby, the position of a certain user at a certain time can be stored as three-dimensional data.

  In step S115, the Web server 30 determines whether or not to estimate the moving means based on the position data stored in the above step. Specifically, if an information acquisition request is received from the mobile communication terminal 10 or another communication terminal, the process proceeds to step S120, and if there is no request, the process ends.

  In step S120, the Web server 30 determines whether there is valid past position data for obtaining the moving means, and reads the past position data and the like from the position information table 60 in step S125. Specifically, the position data of the latest time is read by the same user, but in order to increase the reliability of the speed vector and the moving means obtained in the steps described later, for example, selection is made only by data up to a predetermined time, If only previous data exists, the process ends without performing step S125 and subsequent steps.

  In step S130, the Web server 30 uses the position data and time data received in step S105 and the position data and time data read in step S125 to obtain the difference between them, as shown in FIG. A simple velocity vector (movement direction and speed) is calculated.

  Here, although the displacement of latitude and longitude is obtained in FIG. 6, the displacement of altitude may also be obtained. In that case, it is possible to determine, for example, the ups and downs at the same point. Furthermore, due to the difference in altitude, for example, even on the same railway, it is possible to distinguish between a ground train, a subway, a monorail, and the like, and the estimation of the moving means in step S140 becomes highly accurate.

  In step S135, the web server 30 reads map data related to the periphery of the position data received in step S105. This map data or the like is preferably stored in the Web page DB 30a, the content DB 50a, etc., and includes information on various transportation means that can be used by the user.

  In step S140, the web server 30 estimates the moving means of the user carrying the mobile communication terminal 10 based on the velocity vector obtained in step S130 and the map data read in step S135. Specifically, for example, a moving means table 70 shown in FIG. 7 is used.

  The movement means table 70 stores the minimum speed and the maximum speed for each of the identifiable movement means. Thereby, the corresponding moving means can be determined according to the magnitude of the velocity vector.

  Further, by storing data relating to the rules for estimating the moving means using the table in this way, it is possible to add or change as appropriate. For example, each user has a moving means table 70 (or a user identification field is added). Thus, it is possible to customize the rules for estimating the moving means for each user. For example, if you don't have a bicycle, you don't need a bicycle record, and if you are a jogger, you can customize it by adding a record to that effect. Estimation is possible.

  Here, for example, when the speed is 80 km / h, the moving means is either a train or a car, but there is a possibility that they can be distinguished by referring to the altitude or the map data read in step S140. For example, if it is moving on a train route, it can be estimated that the moving means is a train. If the altitude is different even at the same latitude and longitude, it can be estimated that the highway is moving by a car.

  Further, together with the map data read in step S140, for example, data such as train schedules, bus schedules, and timetables may be read. Thus, there is a possibility that the moving means can be obtained with high accuracy by comparing with the time data.

[Content transmission processing]
FIG. 8 is a diagram showing a flow of content transmission processing according to an example of the preferred embodiment of the present invention. In this process, additional information suitable for the user is provided based on information such as the moving means obtained in the moving means estimation process (FIG. 4).

  In step S <b> 205, the web server 30 receives a content request from the mobile communication terminal 10. In response to the content request, the Web server 30 provides content suitable for the user's movement status (position, movement means, etc.) in subsequent steps.

  In step S <b> 210, the Web server 30 performs the above-described movement means estimation process (FIG. 4) and obtains the movement means of the mobile communication terminal 10. Through this step, the Web server 30 also acquires the position data, time data, and speed vector of the mobile communication terminal 10.

  In step S215, the content server 50 receives the request for additional information from the Web server 30, and from the information stored in the content server 50 or another server, the position data, time data, and speed acquired in step S210. Appropriate content data is searched based on the vector and the moving means data. Specifically, for example, as schematically shown in FIG. 9, information on restaurants, stations, airports, and the like in the moving direction is searched based on moving means.

  In this way, information suitable for transportation means can be acquired, such as coupons for restaurants when walking, traffic information when searching for cars, route search, and flight information. Further, by using the time data, it is possible to acquire timely information such as restaurant business hours and transportation timetables.

  In step S220, when receiving the content data searched in step S215, the web server 30 generates display data to be presented to the user, and transmits the display data to the mobile communication terminal 10 in step S225.

[Position prediction processing]
FIG. 10 is a diagram showing a flow of position prediction processing according to an example of the preferred embodiment of the present invention. In this process, the position of the mobile communication terminal 10 at a future time is predicted and displayed.

  In step S <b> 305, the Web server 30 receives data indicating the destination from the communication terminal 15 together with data identifying the mobile communication terminal 10 or the user whose position is to be predicted.

  The subsequent steps can be executed only when the user of the mobile communication terminal 10 permits it. In that case, for example, data indicating permission from the mobile communication terminal 10 may be received, or the presence or absence of permission between users may be stored in advance.

  In step S <b> 310, the Web server 30 performs the above-described movement means estimation process (FIG. 4) and obtains the movement means of the mobile communication terminal 10. Through this step, the Web server 30 also acquires the position data, time data, and speed vector of the mobile communication terminal 10.

  In step S <b> 315, the web server 30 estimates the movement route of the mobile communication terminal 10. Specifically, a route from the current position to the destination acquired in step S305 is obtained from the current position based on the data acquired in step S310. For example, if the current means of transportation is a train, a predetermined rule is stored in advance, such as connecting a train to the nearest station of the destination, and walking from there or using a bus if there is a distance. Good.

  In step S320, the Web server 30 predicts the arrival time of the mobile communication terminal 10 at the destination. Specifically, for example, the required time is calculated on the assumption that the vehicle moves at a predetermined standard speed along the moving route / moving means obtained in step S315.

  In this way, the travel route to the destination and the expected arrival time are obtained. If data such as a timetable of a train or bus is acquired in step S310 or S315, for example, waiting time or the like. It is possible to obtain more reliable information in consideration of the above.

  In step S325, the Web server 30 transmits display data for presenting the current location, travel route, expected arrival time, and the like to the communication terminal 15. Specifically, for example, the communication terminal 15 performs display such as the screen example shown in FIG. In this example, a display indicating the user of the mobile communication terminal 10 and its current location, a display indicating the destination, and a display indicating the predicted arrival time are performed on the map.

  Here, the display indicating the current location may be an image (icon) corresponding to the moving means. For example, an image of a car is displayed when moving by a car, and a human image is displayed when walking. As a result, the user can easily confirm the moving means.

  In step S <b> 330, the web server 30 receives a designated time for predicting the position of the mobile communication terminal 10 from the communication terminal 15. Specifically, for example, in the example shown in FIG. 11, when the user moves the scroll bar at the bottom of the screen in the communication terminal 15, the time that the user wants to see is set between the current time and the expected arrival time. Further, for example, a display in which a plurality of links linked to a predetermined number of times are embedded (not shown) may be used.

  In step S335, the Web server 30 estimates the position of the mobile communication terminal 10 at the designated time received in step S330. Specifically, for example, the mobile communication terminal 10 moves according to the movement route obtained in step S315 at the standard speed used when obtaining the expected arrival time, and specifies the position at the specified time on the map. .

  In step S340, the estimated display data indicating the position at the specified designated time is transmitted to the communication terminal 15. Note that the estimated display data does not have to rewrite all the screen displays in the communication terminal 15, and at least includes only the changed points. In that case, the communication terminal 15 changes the display without reading the entire screen by rewriting the display of the changed portion in response to receiving the estimated display data. This may reduce the irritability of the user of the communication terminal 15 associated with screen reading.

  In step S345, the Web server 30 determines whether or not to end the position prediction process. Specifically, for example, the communication terminal 15 accepts an input to end the process, and the process ends in response to the Web server 30 receiving data indicating the end. If not finished, the process returns to step S330 to enable position prediction at another designated time.

[Inter-group communication]
In the embodiment described so far, the number of the mobile communication terminals 10 that provide the position information is one. However, the position information regarding the plurality of mobile communication terminals 10 belonging to the group registered in advance may be used. In that case, for example, a group to which a plurality of users belong is stored by the group member table 80 shown in FIG. As a result, the Web server 30 can acquire information on a plurality of users belonging to the same group by referring to the group member table 80 as appropriate.

  FIG. 13 is a diagram showing a flow of group member position information display and message transmission processing according to an example of the preferred embodiment of the present invention.

  In step S410, the Web server 30 performs the above-described movement means estimation process (FIG. 4), and obtains the current positions, velocity vectors, and movement means of the mobile communication terminals 10a, 10b, and 10c.

  In step S415, the Web server 30 generates and transmits display data to be displayed on the mobile communication terminal 10a with respect to the data obtained in step S410. Thereby, the mobile communication terminal 10a displays a screen as shown in FIG. 14, for example. In this example, according to Mr. A's request, the current position including Mr. B and Mr. C, the velocity vector, and the moving means are displayed. Here, as described with reference to FIG. 11, it is preferable to display an image corresponding to each moving means so that the moving means can be easily confirmed.

  In step S420, the mobile communication terminal 10a accepts a message transmission destination selection input. Thereby, the user of the mobile communication terminal 10a can select the other party who wants to contact from other users belonging to the group displayed in step S415.

  In step S425, the mobile communication terminal 10a receives an input of a message from the user, and in step S430, transmits message data to the partner mobile communication terminal 10b or 10c selected in step S420.

  Thereby, the user of the mobile communication terminal 10a can transmit a message by selecting from the display data to, for example, a friend who is heading to the same place or a friend who seems to pass nearby.

[Automatic message transmission]
FIG. 15 is a diagram showing a flow of automatic message transmission processing according to an example of the preferred embodiment of the present invention.

  In step S505, the Web server 30 reads identification data of users belonging to a predetermined group. Specifically, for example, in the group member table 80, users corresponding to the same group are extracted.

  In step S510, the Web server 30 performs the above-described movement means estimation process (FIG. 4), and obtains the current position, velocity vector, and movement means of the mobile communication terminal 10 carried by the user read in step S505.

  In step S515, the Web server 30 calculates the distance between users based on the obtained current position, velocity vector, and moving means, and in step S520, it is determined whether there is a user approaching the predetermined distance. To do. At this time, not only the current position but also the velocity vector and moving means can be used to determine the possibility of approach in the future. If there is a user approaching the predetermined distance, the process proceeds to step S525, and if not, the process ends.

  In step S525, the Web server 30 acquires a message stored in advance for the user determined to be approaching in step S520, and in step S530, the Web server 30 acquires the acquired message to the mobile communication terminal 10 of the user who is approaching. Send message data.

  FIG. 16 is a conceptual diagram showing an example of automatic message transmission processing. In this example, among Mr. A, Mr. B, and Mr. C belonging to the same group, it is determined that Mr. B and Mr. C are approaching, and a message from Mr. B is transmitted to Mr. C.

  In this way, when users belonging to the same group are nearby or approach each other, this is automatically notified, and the group members are given an opportunity to communicate.
