Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a content distribution system using a computer system, and in particular, when passing through a divided area of a map plane space, the user can operate each area without operating the terminal. The present invention relates to a position dependency information providing system for delivering the set content (position dependency information) to a corresponding mobile terminal in a push type.

2. Description of the Related Art Conventionally, as a means for a store to carry out an advertisement targeting migrants (pedestrians, vehicles, etc.) in the vicinity, advertisement contents, maps, telephone numbers, etc. are printed on printed materials such as posters, signboards, leaflets, etc. Then, it is known to advertise the shop. However, in the method of advertising using the printed matter, the opportunity for the moving person to browse the printed matter of the advertisement exists only in the place where the printed matter of the advertisement exists. Therefore, the method of advertising using printed matter has a drawback in that the information provider of the advertisement cannot be a means for widely advertising to the migrants around the store targeted for advertising. In addition, in the method of advertising using printed materials, it is necessary to post the printed material of this advertisement in a place where there are many moving persons in order to improve the browsing rate of the advertisement. However, there is a drawback in that effective advertisement cannot be performed if it cannot be posted.

In order to solve the above-mentioned problems, a GPS (Global Positioni) is applied to a personal computer as a portable mobile terminal such as a notebook size or a palmtop size.
ng System: Global Positioning System) is installed, and information around the current position of this personal computer
Connected to a mobile computer network,
From a service center that provides location-dependent information,
Distribution is performed based on the request of the personal computer. The mobile computer network mentioned here indicates a network (including a public line and the Internet) to which a mobile computer can connect. That is, in the conventional position-dependent information providing system, the service center has a management and search system for position-dependent information that is position-dependent area information and store information, and is uplinked from a mobile terminal. Based on the information of the current position, it is possible to distribute the position dependency information of the shops or the like searched within a fixed range (for example, a radius of 1 km) from the current position to each personal computer.

Further, in the position-dependent information providing system, there is a homepage or the like that presents introductions of shops collectively by region and genre on a computer connected to the Internet. Then, on this home page, the user selects the region or genre for which information is desired by clicking on the map displayed in the image or inputting the region name or latitude / longitude data, and narrows down the information interactively. You can browse the page (where position dependency information is written) that introduces the shops you want to know about.

[0005]

However, the above-mentioned conventional position dependency information providing system is a homepage that discloses the introduction of shops and the like by region, and is present in the vicinity of the shops and the like to be advertised. Instead of delivering advertisements directly to the mover, the mover needs to access and browse the public website, so the mover needs to notify (uplink) the current location information. Is. In addition, when the position dependency information providing system transfers the position dependency information of the corresponding area to the mobile terminal according to the current position information from the mobile terminal of the mover, the mover must always notify the current position information. The communication cost will not be negligible. Furthermore, since the position dependency information providing system does not have information about the presence or absence of the position dependency information of the category that the user wants to provide at each point in the movement route through which the mover passes, the position dependency information cannot be obtained. Regardless of the location, there is a drawback that the mobile terminal performs a wasteful process of notifying the current location information.

Further, in the conventional position-dependent information providing system, the distribution information (content) to be distributed is registered as position-dependent information, and the distribution corresponding to the location of the information provider of this distribution information is registered. However, this information provider has the drawback that the information provider cannot arbitrarily set the area for distribution. Further, as described above, the conventional position-dependent information providing system only registers the delivery corresponding to the location of the information provider of the delivery information, and provides the time zone for delivering the delivery information. However, there is a problem in that it cannot be set by a person who is not able to set the information, and the information cannot be delivered at a time according to the content of the delivery information desired by the information provider.

[0007] The present invention has been made under such a background, and the useless present position information for requesting the position dependence information is set at the point where the position dependence information distributed by the mobile terminal is not set. A location where a mobile person can obtain location-dependent information at a timely location and time without performing an uplink (notification), and can transmit location-dependent information at a location and time desired by an information provider. To provide a dependency information distribution system.

In this case, the communication server 7 reads out the detailed position dependency information from the content server 14 in correspondence with the information registration number indicated by the information providing server 8,
The read position dependency information is transmitted to each mobile terminal 3. The map server 9 divides the map plane space of a predetermined area into a plurality of areas by a mesh having an arbitrary size, and defines the map as an aggregate of a plurality of areas as shown in FIG. The intervals of this mesh are changed according to the distribution state of the position dependency information, that is, in areas with a large amount of information to be distributed such as tourist spots and urban areas, it is fine (for example, at intervals of 1 km), and in mountainous areas and coastlines. Large in areas where the amount of information distributed is small (for example, at intervals of 3 km)
It is set (information indicating the form of division by the mesh shown in FIG. 2).

The position detection server 10 detects in which of the above-mentioned areas the mobile terminal 3 (that is, the vehicle 2) is present based on the current position information from the mobile terminal 3. Further, the position detection server 10 determines, based on the movement route from the departure area for departure to the intended destination area, which is transmitted from the mobile terminal 3 at the time of departure, the area through which the movement route passes, as shown in FIG. The data is extracted on the basis of the data of the area shown in (1) and the movement route, and the extracted area is output to the information providing server 8 as a selected area through which the movement route passes. That is, the position detection server 10
The area including the movement route is selected as the selected area based on the area information (information indicating the form of division by the mesh shown in FIG. 2). Here, the position detection server 10 assigns an area order to each selected area in the order in which the vehicle 2 passes on the moving route, and the information of this area order is also provided together with the area information (including the area number) of the selected area. Output to the server 8. The information registration unit 11 includes a customer file indicating customer registration information of the information provider of the detailed position dependency information, position dependency information in which minimal advertisement information is extracted and simplified, and the position dependency information. Is set up with an information file indicating which area is to be delivered and in which time zone, and these files are stored. Hereinafter, when the position dependency information is simply used, it is registered in the information registration unit 11,
The minimum advertisement information is extracted and the simplified position dependency information is shown. Next, the configuration of the information registration unit 11 will be described in detail with reference to FIG. The information registration unit 11
It comprises an information registration server 11a, an information provider profile database 11b, and a distribution information database 11c.

Information provider profile database 11
The customer (information provider) file shown in FIG. 4 is stored in b. This customer file is created one for each customer, and the customer registration number is used as a search key, and the registrant ID (identification number), name (for example, store name in the case of a store), address, position on the map Information (x (longitude), y (latitude)), phone number, fax number, industry code, URL
(Uniform Resource Locator), email address,
Data such as a journey (a brief route description), business hours, the number of cars that can be parked in a parking lot, and the number of seats (for example, a dining room or a restaurant) are described. Also, the distribution information database 11c
Stores the information file shown in FIG. Here, one information file is created for each position dependency information, and a plurality of information files may exist for one customer. In this information file, the customer registration number, information name, information category, and information registration number are used as search keys.
A distribution area for distributing the position dependency information indicated by this information file, a distribution time zone for distributing the position dependency information indicated by this information file, an advertisement message, and a URL to the content server 14 in which detailed position dependency information is stored. Data such as is described. Here, the customer file and the information file have a common customer registration number, and constitute a database of parent-child relationship (the customer information file is the parent).

Further, a distribution list is described by using a data format that can be identified by a browser installed in the mobile terminal 3, for example, the HTML language shown in FIG. 4, and the distribution list is used as position dependency information and an information registration server. 11a is registered in the distribution information database 11c in association with the information registration number. In addition, the information file is stored (arranged) in the distribution table shown in FIG. 5 in association with the area number assigned to each area and the distribution time zone. Information such as meals, gas stations, convenience stores, florists, ..., Hospitals and tourist information is created for each category in the distribution table of FIG. In addition, the information file corresponds to the number of position dependency information to be distributed for each column indicating a distribution list to be distributed under these conditions, which is designated by each area number and distribution time zone in the distribution table. , And a single or plural is set, and when plural are set, the queue is formed in descending order of priority. Here, the information providing server 8 extracts the distribution list (position dependency information) corresponding to the information registration number of each information file from the distribution information database 11c via the information registration server 11a in the order of high priority. The extracted distribution list is distributed to the mobile terminal 3.

Returning to FIG. 1, the information providing server 8 is set to the time zone defined as the distribution time zone in the area of the area number defined as the corresponding distribution area based on the distribution table of FIG. 5 described above. The distribution list is distributed to the mobile terminal 3 via the communication server 7 as the position dependency information. The distribution of the position dependency information is performed by the process of prefetch distribution, which will be described in detail in the operation part. At this time, the information providing server 8 distributes in the order of the area order based on the information of the selected area output from the position information detecting server 10 from the distribution table corresponding to the category transmitted by the mobile terminal 3 in the departure area. The presence or absence of the sex information is detected, and the area where the position dependency information exists is extracted.

In the information providing server 10, the number of set position dependency information is set to a preset lower limit number a (for example, 1 or 2) even in the area having the position dependency information.
When it is detected that the number is smaller than the number of the above), these plural areas are collectively set as a distribution area. Here, when the information providing server 10 puts together a plurality of selected areas, the number of selected areas (the number of distribution areas) to be put together at one time is less than a preset upper limit number b, and the number of position dependency information is Add restrictions so that they can be suppressed. This upper limit number b is set so that the distribution time zone of each of the selected selected areas does not significantly deviate from the wish of the information provider (for example, within 1 hour depending on the speed of the vehicle 2). So that it fits in the gap
Make sure to calculate for each car 2). Through the above-described processing, the information providing server 10 delivers the position dependency information of each delivery area to the mobile terminal 3 in the information providing area for prefetching.

The processing unit 3B includes a CPU (central processing unit),
It consists of memory, hard disk, etc., has a browser installed, interprets HTTP (HyperText Transfer Protocol) which is an Internet protocol, and displays the position dependency information distributed from the service center C on the screen shown in FIG. The data is displayed on the display unit 3A. Further, on this screen, the URL of the content database 14 in which more detailed position dependency information of the information of this distribution list is stored is put up as a link destination. Moving person (delivered user who receives position-dependent information by moving in a vehicle 2 equipped with a mobile terminal 3)
When the user wants to obtain detailed information, he / she can click on the above URL to move to the home page of the content server 14 having the detailed position dependency information prepared by the information provider.

Next, an operation example of one embodiment of the position dependency information providing system according to the present invention described above will be described. <Detection of an area in which a migrant is present>
In the vehicle 2 that has arrived the mobile terminal 3, the current position information (latitude / longitude) detected by the position detection device 1 is uplinked to the position detection server 10 at the point where driving is started. Thereby, the position detection server 10
Can detect the currently existing area of the vehicle 2 from the current position information based on the area information in which the map plane space in the map server 9 is divided by a mesh and the latitude / longitude on the map. Then, the position detection server 10
Transmits to the mobile terminal 3 section information in which the range of the area in which the vehicle 2 exists is represented by latitude / longitude from the area information and latitude / longitude of the map.

The mobile terminal 3 indicates that the mobile terminal 3 has entered a different area from the existing area by advancing along a moving route to the destination, and present position information output from the position detecting device 1 and the section information. Can be detected by comparing Then, the mobile terminal 3 detects the movement from the area to another area, and when the destination area is the information providing area, the mobile terminal 3 uplinks the current position information to the position detecting server 10 in the information providing area. The information providing area will be described in detail later. At this time, the mobile terminal 3 includes the position detection server 10 as mobile terminal information including not only the current position information but also speed information indicating the moving speed of the vehicle 2 measured by the vehicle speed sensor mounted on the vehicle 2. Send to. As a result, the position detection server 10 stores the area information in the map server 9,
Based on the latitude / longitude on the map, the information providing area of the destination of the vehicle 2 can be detected from the current position information. Then, the position detection server 10 transmits to the mobile terminal 3 the section information of the area where the vehicle 2 has entered and the section information of the information providing area.

By repeating this process, the position detection server 10 can always track the area where the vehicle 2 (that is, the mobile terminal 3) exists. Further, the mobile terminal 3 may transmit the current position information to the position detection server 10 only when the mobile terminal 3 passes through the boundary of the information providing area based on the partition information transmitted from the position detection server 10. Therefore, the mobile terminal 3 uses the current position information as the position detection server 1
It is no longer necessary to send the data to 0 to constantly connect the line or connect the line at a short cycle to constantly notify the position detection server 10 of the current position, thereby reducing the communication charge.

<Pre-reading Distribution of Position Dependency Information> Next, referring to FIGS. 1, 2, 3, 6 and 8, the movement route of the vehicle 2 has been notified to the service center C in advance, A process of determining the information providing area to which the position dependency information is distributed based on the number of position dependency information set in each area passing through the movement route will be described. Figure 6
It is a conceptual diagram which shows the relationship between the movement route RT of the vehicle 2 and a selection area. FIG. 8 is a conceptual diagram showing the selected area extracted from the area information based on the movement route. As described above, in the present invention, the position detection server 10 is notified in advance of the moving route RT from which the vehicle 2 travels, that is, the route from the starting point to the destination. In FIG. 6, it is assumed that the car 2 moves on the movement route RT. The mobile terminal 3 transmits the current position information detected by the position detection device 1 to the position detection server 10 at the distribution start point A where the vehicle 2 is currently present when the mover requests the start of distribution of the position dependency information. Uplink (send) to. At this time, the information providing server 8 also receives the request to start the distribution, and the categories shown in FIG. 7, for example, meal, gas station, convenience store, florist, ..., Hospital,
The image data of the screen of the selection table showing the types of categories such as tourist information is transmitted to the mobile terminal 3.

Then, the mobile terminal 3 displays the image data of the table showing the type of the inputted category on the display section 3a as the selection table. Below, in order to distinguish from the processing of the browser in the mobile terminal 13 already described,
It is described that the mobile terminal 3 performs the process performed by the browser installed in the processing unit 3b. In the table of the display unit 3a, the mobile terminal 3 clicks and selects a category, for example, a meal, a gas station, or tourist information that the traveler desires to deliver (for example, selects a meal, a gas station, or tourist information). Transmits the information of the selected category to the information providing server 8. In addition, the process of selecting the category of position dependency information for which this distribution is desired
A personal computer (not shown), such as the home of the mover, may be connected to the service center C to connect the line.
As a result, the information providing server 8 causes the position detection server 10 to
Based on the detected area, the information file of the position dependency information set in this area is shown in FIG. 5 for each category of the selected meal, gas station and tourist information stored in the distribution information database 11c. The respective distribution tables shown are searched.

In the pre-read distribution, the movement detection route detected by the car navigation system or the like is transmitted to the position detection server 10 together with the distribution start request (at the distribution start point A).
At the departure place (delivery start point A), the area passing from the departure place to the destination is extracted from the area information of the map server 9 based on the information of the movement route RT. Then, the position detection server 10 sets the area extracted from the area information as a selected area as shown in FIG. At this time, the position detection server 10 gives an area order indicating the order of passage to each selected area.

Then, the position detection server 10 divides the mesh interval of the passing area by the speed (speed information) of the vehicle 2 every time the boundary of each area is crossed, and thereby the passing time required for passing each area is obtained. Calculate Here, the position detection server 10 simplifies the calculation of the above transit time,
In the case where the distance traveled in the horizontal direction is long with respect to the figure, the horizontal distance in the mesh of the area is divided by the speed of the car 2, and when the distance traveled in the vertical direction is long, the vertical distance in the mesh of the area is divided by the car 2. Calculate the transit time by dividing by the speed of. Although the distribution start point A may not distribute position-dependent information in a distribution time zone including the time obtained by adding the current time and the desired readahead time, the current position information, the category, and the desired readahead time may be calculated by the mobile terminal 3 Since it is notified by, it is exceptionally positioned as an information providing area.

Using FIG. 1, FIG. 3, FIG. 8 and FIG. 9, the operation of the position dependency information providing system which is one embodiment of the present invention other than transmitting the position dependency information in each information providing area will be described. explain. Here, FIG. 9 is a flowchart showing an operation example of the position dependency information providing system. For explanation,
As a state before step S1, the vehicle 2 on which the traveler boarded
However, for example, it is assumed that the train starts from area n-2. Here, the mobile terminal 3 receives the point P based on the operation of the mover.
At n, the service center C is notified of the distribution start signal requesting the distribution of the position dependency information, the category of the position dependency information desired to be distributed, and the movement route. As a result, the position detection server 10 extracts the selected area of FIG. 8 from the area information of the map server 9 based on the obtained movement route. That is, the position detection server 10
The distribution start point A is the point Pn in the area n-2, and the car 2 sequentially receives the area order n-2, n-1, in FIG.
The movement information of the vehicle 2 that the vehicle passes each area in the order of n, n + 1, n + 2, ..., N + 6 ,. In step S1, the information providing server 8 resets the distribution area number N indicating the number of selected areas, which is a collection of the position dependency information to be distributed, to “0”, and advances the processing to step S2. The number of distribution areas is
It is stored inside the information providing server 8.

Next, in step S2, the information providing server 8 stores the position dependency information in the columns corresponding to the area n-2 and the distribution time zone including the current time in each distribution table desired by the mover. It detects whether or not it is set. Then, in the information providing server 8, the position dependency information is not set in the column corresponding to the area n−2 and the distribution time zone including the current time, that is, the in-area information distribution number En is “0”. When this is detected, the process proceeds to step S3. On the other hand, the information providing server 8 uses the area n-
If the position dependency information is set in the column corresponding to 2 and the distribution time zone including the current time, that is, if the number of in-area information distribution En is not "0", the process proceeds to step S4.

Next, in step S3, the information providing server 8 increments the area order of the selection areas for detecting the position dependency information, that is, selects the selection area for detecting the position dependency information as the area n-. From 2 to area n-1, the process returns to step S2. Then, in step S2, the information providing server 8 determines the area n-1.
The presence or absence of the position dependency information of is pre-read. At this time, the information providing server 8 uses the distribution table of each category as follows.
Current time to uplink and area n at this current time
Determination of whether or not the position dependency information is set in the column corresponding to the distribution time zone and the area n-1, which overlaps the transit time zone between the time points obtained by adding the transit times of −2 and n−1. I do. Here, the passage time zone between the current time and the time obtained by adding the passage time of the area n−2 may overlap with a plurality of delivery time zones in the distribution table.

Then, the information providing server 8 uses the area n-
If it is detected that the in-area information distribution number En of 1 is "0", the process proceeds to step S3. As a result, in step S3, the information providing server 8 changes the selection area for detecting the position dependency information from area n-1 to area n, and returns the processing to step S2. Then, in step S2, the information providing server 8 displays the current time and the areas n-2 and n- in the distribution table of each category.
It is determined whether or not the position dependency information is set in the column corresponding to area n and the distribution time zone that overlaps the transit time zone between the times obtained by adding the transit times of 1 and n. That is, the information providing server 8 passes through the selected area that is being searched and the time from the current time to the time when the selected area is being searched until it detects a selected area in which the number of in-area information distribution En is not "0". In each column corresponding to the distribution time zone overlapping the time zone, it is detected whether or not the position dependency information is set in this (or these) field. At this time, if the information distribution server 8 confirms that the in-area information distribution number En in the area n is not "0", the process proceeds to step S4.

Next, in step S4, the information distribution server 8 determines whether or not the in-area information distribution number En in the area n exceeds the lower limit number a. At this time,
When the information distribution server 8 detects that the in-area information distribution number En in the area n exceeds the lower limit number a, the process proceeds to step S5. Next, in step S5, the information providing server 8 reads the detected position dependency information from the distribution information database 11c, and distributes the read position dependency information to the mobile terminal 3. After delivering the position dependency information as described above, the information providing server 8 obtains the next information providing area by incrementing the number of the area order which is the currently selected area, that is, the number of the area n. Area n +
1 is set as the next information providing area, and this information is delivered to the mobile terminal 3.

That is, the information providing server 8 uses the area n
Area n + 1, which has passed through the boundary between the area n + 1 and the area n + 1, is the information providing area, and the partition information of the area n + 1 is distributed to the mobile terminal 3 in order to uplink the current position information at the point Pn + 3. At this time, the information providing server 8 stores the information registration number of the position dependency information transmitted to the mobile terminal 3, and the transmission history of the position dependency information so that the same position dependency information is not transmitted to the mobile terminal 3. Manage. That is, the information providing server 8 prevents double delivery of the same location dependency information to the mobile terminal 3. Then, when the position detection server 10 detects that the vehicle 2 has entered the area n + 1 by the uplink at the point Pn + 3 of the current position information from the mobile terminal 3, it informs that the vehicle 2 has entered the area n + 1. The providing server 8 is notified and the process returns to step S2.

Next, in step S2, the information providing server 8 sets a column corresponding to the distribution time zone including the current time and the area n + 1 in the distribution table of each category.
It is determined whether or not the position dependency information is set, that is, whether or not the in-area delivery information number En is “0”. Then, when the information providing server 8 confirms that the number of in-area delivery information En in the area n + 1 is not "0", the process proceeds to step S4. Next, step S
In 4, the information providing server 8 determines whether or not the in-area information distribution number En in the area n + 1 exceeds the lower limit number a. At this time, when the information distribution server 8 detects that the in-area information distribution number En in the area n is less than or equal to the lower limit number a, the process proceeds to step S6.

Next, in step S6, the information distribution server 8 increments the distribution area number N, that is, "N = N + 1 (N ← N + 1)". Then, the information distribution server 8 adds the in-area information distribution number En in the selected area indicated by the distribution area number N with the area n + 1 as the starting area in the following expression (1), that is, at this time, the area n + 1 Area information distribution number En
Let itself be the distribution information number En in the area.

[Equation 1] Next, the information providing server 8 increments the area order of the selection areas for detecting the position dependency information, that is, sets the selection area for detecting the position dependency information from the area n + 1 to the area n + 2, and the process is performed. Proceed to S7.

Then, in step S7, the information providing server 8 determines whether the distribution area number N exceeds the upper limit number b. At this time, if the number N of distribution areas does not exceed the upper limit number b, the information providing server 8 returns the process to step S4. Next, in step S4, the information providing server 8 detects whether or not the in-area information distribution number En obtained in step S6 exceeds the lower limit number a. Then, the information providing server 8 detects that the in-area information distribution number En obtained in step S6 does not exceed the lower limit number a, and advances the process to step S6.

Next, in step S6, the information distribution server 8 increments the distribution area number N, that is, "N = N + 1 (N ← N + 1)". Here, the information providing server 8 searches for the position dependency information in the area n + 1, and the search method is the same as the method already described in steps S2 and S3. And the information providing server 8
Is calculated by adding the in-area information distribution number En in the selected area indicated by the distribution area number N with the area n + 1 as the starting area in the formula (1), that is, at this time
+1 and area n + 2 within each area information distribution number En
Is added to obtain a new number of in-area distribution information En. Here, the information providing server 8 performs the addition process according to (1) even if the in-area information distribution number En in the area n + 2 is “0”. Next, the information providing server 8 increments the area order of the selection areas for detecting the position dependency information, that is, changes the selection area for detecting the position dependency information from the area n + 2 to the area n + 3, and the process is performed. Proceed to S7.

Then, in step S7, the information providing server 8 determines whether or not the number of distribution areas N exceeds the upper limit number b. At this time, if the number N of distribution areas does not exceed the upper limit number b, the information providing server 8 advances the process to step S4. Next, in step S4, the information providing server 8 detects whether or not the in-area information distribution number En obtained in step S6 exceeds the lower limit number a. Thus, when the information providing server 8 detects that the in-area information distribution number En obtained in step S6 exceeds the lower limit number a, the process proceeds to step S5.

Then, in step S5, the information providing server 8 reads the position dependency information searched for the area n + 1 and the area n + 2 from the distribution information database 11c based on the area number at the point Pn + 3, and reads this. The position dependency information is collectively delivered to the mobile terminal 3. After delivering the position dependency information as described above, the information providing server 8 obtains the next information providing area by incrementing the number of the area order which is the currently selected area, that is, the number of the area n. Is incremented to make the area n + 3 the next information providing area, and this information is delivered to the mobile terminal 3. That is, the information providing server 8 has passed through the boundary between the area n + 2 and the area n + 3,
Area n + 3 that has passed through the two areas is the information providing area (the point obtained by adding the number of distribution areas to the current point becomes the next distribution point), and area n is used to uplink the current position information at point Pn + 5.
The section information of +3 is delivered to the mobile terminal 3. When the information providing server 8 detects that the number N of distribution areas exceeds the upper limit number b in step S7, the process proceeds to step S5. The process of step S5 at this time is the same as that of step S5 mentioned above. The operation of each step described above ends when the pre-reading of the selected areas extracted from the area information is completed based on the movement route and the position-dependent information set in these selected areas is delivered. The information providing server 8 is shown in FIG.
In the process of the flowchart of FIG. 7, in the last information supply area reconstructed from the selected area, the value obtained by adding the in-area information distribution number En of each preselected selection area is the lower limit number a.
The position dependency information is delivered to the mobile terminal 3 even if it does not exceed.

As described above, the position dependency information providing system of the present invention always updates the current position information to the service center C when the mobile terminal 3 requests the position dependency information as in the conventional example. Compared with the conventional information providing system that needs to be linked and therefore requires a lot of communication charges, the map plane space is divided into areas by mesh, and the position dependency information is set for each area, and, When there is no position-dependent information to be delivered to the mobile terminal 3 (the number of in-area information delivery En is “0”) or is very small, the selected area is thinned out and the uplink is performed. It is possible to reduce significantly, and it is possible to reduce the communication charge for obtaining the position-dependent information. Here, the number of selected areas to be thinned out is determined by whether the number of in-area information distributions En is “0” continuously, and the relationship between the number of in-area information distributions En and the number of distribution areas N. It

As a matter of course, the information providing server 8 is
If the position dependency information in which the number En of information distributions in the area En exceeds the lower limit number a is set in all consecutive selected areas,
The partition information of the selected area is continuously notified to the mobile terminal 3 so that the current position information is uplinked at all the points Pn to Pn + 1 in FIG. However, in the position-dependent information providing system of the present invention, when the number of in-area information distribution En of each selected area is “0” or very small, it indicates the point to be uplinked next, so that the information is transmitted next. By notifying the mobile terminal 3 of the division information of the information provision area to be provided, the selected area for intentionally uplinking the current position information is skipped, and the number of unnecessary uplinks of the current position information is reduced.
It is characterized by reducing communication charges.

Further, as described above, the position dependency information providing system of the present invention provides position dependency information of a plurality of selected areas when the number of information distributions within each area is small (including "0"). To summarize, when prefetching the information in these selected areas, from the distribution time zone in which the position dependency information is set in the distribution table, until the passage time that passes through all the selected areas from the current time That has an overlap with the passage time zone of, that is, extracts the delivery time zone including the time in the passage time zone,
In order to search the position-dependent information set in the delivery time zone column, the position-dependent information set in the selection area through which the vehicle 2 passes is pre-read in consideration of the delivery time zone of each selection area. Retrieving, reconstructing each of the selected selected areas as one area, and extracting the position-dependent information set in the distribution time zone corresponding to the passage time zone that passes through this one area Therefore, it is possible to satisfy the distribution time zone desired by the information provider and collectively distribute the position-dependent information set by the information provider to the mobile terminal 3 in a plurality of areas.

Further, according to the above-described default distribution, the position dependency information providing system of the invention of the present application requests the position dependency information desired by the migrant at the time of departure by designating a category. Since it is possible to save the trouble of operating the mobile terminal 3 to obtain the necessary position dependency information during the movement, it is possible to obtain the necessary position dependency information at an appropriate timing. In addition, in the position-dependent information providing system of the present invention, the information provider provides the position-dependent information to the service center C in advance for each area obtained by dividing the map plane space with a mesh and by designating a distribution time. Since the setting is made, there is an effect that the position dependency information can be delivered to the moving person in a timely manner without paying attention to the delivery processing.

Furthermore, according to the information registration of the position dependency information described above, whether or not the position dependency information is distributed to the area in which the map plane space is divided by the mesh and the distribution time zone for each area. In order to set, when the information provider tries to deliver the position dependency information that is an advertisement, it is possible to select the most effective delivery area and delivery time zone for the advertisement content of this information provider, And the category is moved in advance (receiver of the position-dependent information to be distributed)
The cost performance in advertisement distribution is improved compared to the case where push-type position-dependent information is distributed to those who do not need the information or those who are scattered over a wide area. It becomes possible.

The first embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the design is within the scope of the present invention. The present invention includes modifications and the like. For example, the pre-reading time range (time zone, that is, the passing time zone described later) can be determined by this pre-reading desired time. For example, if the pre-reading desired time notified from the mobile terminal 3 is 2 hours, 2 times from the current time of the uplink.
Position dependency information is distributed to areas that pass in the time zone within the time range (the distance is calculated from the speed of the vehicle and the desired time to look ahead, the passing area is detected, and the area that overlaps the delivery time zone). Good. The method of searching the position dependency information at this time is the same as the method of searching the position dependency information in the distribution time zone of each area described above.

Further, a program for realizing the operation shown in the above-described embodiment is recorded in a computer-readable recording medium, and the program recorded in the recording medium is read by a computer system.
The position dependency information may be distributed by executing the distribution process. The “computer system” mentioned here includes an OS and hardware such as peripheral devices. The "computer-readable recording medium" means a flexible disk, a magneto-optical disk, a ROM,
It refers to a portable medium such as a CD-ROM or a storage device such as a hard disk built in a computer system.

Further, the "computer-readable recording medium" means a program dynamically for a short time like a communication line in the case of transmitting the program through a network such as the Internet or a communication line such as a telephone line. The one that holds the program, and the one that holds the program for a certain period of time, such as the volatile memory inside the computer system that serves as the server or the client in that case, are also included. Further, the above program may be one for realizing some of the functions described above, and may be one that can realize the above functions in combination with a program already recorded in the computer system.
