Description

  The present invention automatically applies to a person in a specific area having a mobile terminal equipped with a global positioning system (Global Positioning System: hereinafter referred to as GPS). The present invention relates to a user terminal suitable for use in providing a service for distributing (pushing) information such as nearby store advertisements to the mobile terminal.

  In recent years, with the spread of mobile terminals (user terminals) such as mobile phones and mobile communication terminals, each company provides a push-type push distribution service (hereinafter referred to as a push distribution service). This push distribution service refers to a mobile terminal from a server system (a plurality of servers including a plurality of servers having a plurality of functions) regardless of whether the mobile terminal is turned on or off or whether or not the mobile terminal is connected to the network. When information is distributed, the mobile terminal can automatically receive the information. Similar to the mail reception in the standby state of the mobile phone, when the mobile terminal receives information from the server system, the mobile terminal notifies the user by a ring tone or the like, thereby confirming that the user has been notified of the information. To know. This method is called that the server system pushes information to the user because the user can obtain information without connecting to the network by himself / herself. Thereby, the user can receive real-time information. On the other hand, a method in which the user connects to the network by himself and obtains information is called that the user pulls information from the server system.

A provider (hereinafter referred to as an administrator) that provides a push distribution service has introduced a method of measuring the terminal position of a mobile terminal using a GPS satellite (hereinafter referred to as “Positioning”). That is, the GPS satellite searches for a desired mobile terminal, registers the position of the mobile terminal, and notifies the mobile terminal of information.
And the administrator has made the data format regarding a terminal position common with the companies etc. which participate in this push delivery service. By using this GPS satellite, a service can be provided to a wide area. Specifically, terminal position determination and storage, acquisition of a third party terminal position, and management and exchange of terminal position information are standardized. Recently, push distribution experiments using GPS satellites have been conducted.

  There are two types of methods for providing a content push delivery service such as store advertisement to a mobile terminal in which a server system is in a specific area. First, in order to determine whether or not the mobile terminal is in the specific area, an ASP (Application Service Provider) periodically measures and checks the mobile terminal. The ASP refers to an administrator who provides computer application software (hereinafter abbreviated as an application) to each user on the server system via the Internet. Secondly, the mobile terminal periodically transmits the measured position (measured terminal position) measured by itself to the ASP.

  However, when the administrator uses a conventional technique to provide a content push distribution service such as a store advertisement, the base station distributes information based on an area (Coverage Area) that covers the mobile terminal. However, the area to be delivered is several kilometers square when the area shape is, for example, a quadrangle, and is also wide even when the shape is circular, so the server system can display store advertisements limited to the vicinity of the user's position. There is a problem that it cannot be pinpointed accurately.

  In addition, the above-described method using GPS, regardless of which of these methods is used, the ASP or mobile terminal always measures the terminal position of the mobile terminal, so the mobile phone network and the server system for positioning Both the load increases. Furthermore, since the mobile terminal and the mobile phone network regularly measure the terminal position, there is a problem that a burden for processing the packet becomes large.

Accordingly, when the user uses the location information service, there is a problem that the packet fee to be paid increases.
The present invention was devised in view of such a problem, and by reducing the number of positioning by predicting that the user terminal has entered a plurality of push delivery areas existing around the user terminal itself, An object of the present invention is to provide a user terminal that enables content push distribution such as store advertisements in a pinpoint manner.

In addition, each mobile terminal 1 is connected to the data center 19 via the communication network 101, and attribute information (C, R) including the position C and the range R of the push distribution areas A to J received on the terminal side. Can be predicted that the mobile terminal 1 itself belongs to the push distribution areas A to J by comparing the mobile terminal 1 with the predicted self-predicted position (L1-a, L1-b, L1-c). Therefore, the mobile terminal 1 predicts the terminal position without frequently measuring the spatial position of the mobile terminal 1 itself. Therefore, the number of times the actually measured data is transmitted / received to / from the positioning server 10 via the communication network 101 is reduced, thereby greatly reducing the burden on the communication network 101 and transmitting / receiving data using the burden. Can be speeded up.

(1-3) Service Method Applying Information Balloon to Push Distribution Service FIG. 6 is a view for explaining a push distribution service providing method according to an embodiment of the present invention. The balloon B shown in FIG. 6 is a spherical balloon that represents the forefront store among a number of stores. Here, in the database world of the data center 19, the balloon B is in contact with the user having the mobile terminal 1. In other words, in FIG. 6, a composite image in which the real space in which the central street and the stores on both sides of the street are present and the balloon B are superimposed is displayed.

  Specifically, when the push distribution service providing system 200 push-distributes the advertisement of each store to the mobile terminal 1, the latitude, longitude and altitude data of the balloon held in the server of the data center 19, The latitude, longitude, and altitude data of the portable terminal 1 overlap, and the data center 19 extracts the service provided by the balloon in the overlapped portion. Thus, conceptually, the moving user and the balloon appear to be in contact, and the user appears to automatically receive the advertisement contained in the contacted balloon. The advertisement using the balloon makes it possible to push the advertisement distribution of the company or the store to the mobile terminal 1 as described in the above (1-1) and the push distribution of the business information to the specific user in the company. . This push distribution function is referred to as a HotSpot (application trademark of NTT Communications Corporation) function.

(1-4) Description of HotSpot Service FIG. 20 is a diagram showing a first example of a HotSpot service according to an embodiment of the present invention. The push distribution area E shown in FIG. 20 pushes, for example, information related to the sale of goods to the mobile terminal 1 in the area. Thereby, the administrator can support the purchase in each store.

  FIG. 21 is a diagram showing a second example of the HotSpot service according to an embodiment of the present invention. The push distribution area F shown in FIG. 21 pushes discount information to the mobile terminal 1 in the area, whereby the store can promote sales, and the store attracting effect is improved. In this way, each store can attract customers by pushing information into the push distribution area.

FIG. 22 is a diagram showing a third example of the HotSpot service according to the embodiment of the present invention. The push distribution area G shown in FIG. 22 pushes crime prevention information to the mobile terminal 1. Thereby, information from public institutions can be distributed in one direction.
FIG. 23 is a diagram showing a fourth example of the HotSpot service according to the embodiment of the present invention. The push distribution area H shown in FIG. 23 has a bulletin board function, and an unspecified number of users can share information such as recruitment of music band members or desire to participate.

(2) Configuration of Push Service Providing System 200 The push delivery service providing system 200 shown in FIG. 1 provides a push delivery service to the mobile terminal 1 using an information balloon. This push distribution service providing system 200 holds distribution information (for example, content information) from a company or a store for each information push distribution area, pushes the information to the portable terminal 1 and pulls information from the portable terminal 1 to pull the portable terminal 1. For example, four GPS satellites (artificial satellites) 90, a city area 150 that can receive radio waves from these GPS satellites 90, and a communication network 101 that transmits and receives data to and from base stations. A positioning server 10 connected to the communication network 101, a data center 19 connected to the communication network 101, a portable terminal 1 and a number of other portable terminals 1 (not shown). Yes.

(2-1) City area 150
A city area 150 shown in FIG. 1 represents cities such as Shinjuku and Shibuya, and the range (size) is set according to the design of the transmission power value or the business policy. For example, the area of the city area 150 is set to be small in the city center and large in the suburbs. That is, the division of the space can be maintained by changing the density between the urban area and the suburban area. In the city area 150 shown in FIG. 1, a plurality of push delivery areas A to J are displayed.

(2-2) Push distribution areas A to J
The push distribution areas A to J are areas where the mobile terminal 1 is pushed various information. Specifically, when the push delivery service providing system 200 determines that the mobile terminal 1 is in any one of the push delivery areas A to J, information such as news or the like is currently present with respect to the mobile terminal 1. It pushes various store advertisements in the vicinity of the location.

This push distribution area setting example will be described in further detail.
The data center 19 divides the city area 150 shown by the hatched portion in FIG. 1 into a plurality of push delivery areas A to J. The shapes of the plurality of push delivery areas A to J are all elliptical, polygonal, or a combination of parts of these shapes in addition to a circle having a desired radius, or a spherical or columnar three-dimensional shape. It can also be. Further, the radius is set in various sizes depending on the area (distance from the city center), the contract fee or the use of the advertisement.

  Thus, the plurality of push distribution areas A to J individually send their own advertisements to the user by paying the contract fee to the data center 19. For example, a store belonging to the push distribution area G transmits a message “I will start a time service from 17:00” to the mobile terminal 1 in the push distribution area G. Further, for example, another store belonging to the push distribution area E can advertise that “a popular video game has arrived”.

Therefore, each store can directly advertise the store to people moving near the store by walking or by vehicle, etc., and information is instantly compared with broadcast media or paper-based advertisements such as newspapers and magazines. Can provide.
This makes it possible to provide fine-grained services such as time services. In addition, this makes it possible for each store to advertise individually or in a pinpoint manner to a customer group limited to a specific age, sex, or occupation. Moreover, the public institution can transmit desired information to a specific user selected from many users.

(2-3) GPS satellite 90
Each of the four GPS satellites 90 shown in FIG. 1 is arranged in a plurality of circular orbits having an altitude of 20,000 km and covers the city area 150 as an area that can be received. Each GPS satellite 90 has an accurate atomic clock and transmits data including a radio wave transmission time and a satellite ID (Identification). And in the city area 150, the portable terminal 1 receives the radio wave from each GPS satellite 90, and calculates the distance between each GPS satellite 90 and the receiving point of the terminal itself based on the reception time. Specifically, the portable terminal 1 can measure the self position (position of the portable terminal 1 itself), the moving direction, and the moving amount in a three-dimensional space range of, for example, a sphere, an elliptic sphere, a cube, or a rectangular parallelepiped. 1 can accurately measure latitude, longitude, altitude, and the like.

Here, the moving direction is an azimuth or direction in a two-dimensional plane, and an elevation or depression angle is added to the azimuth or direction in a three-dimensional space. Further, the movement amount is a distance that the mobile terminal 1 has actually moved. In this embodiment, it is assumed that the user moves without hesitating the same place.
This actual measurement is calculated by the mobile terminal 1 itself using an application provided in the mobile terminal 1. Since this calculation amount is large, since the mobile terminal 1 calculates itself and no calculation data is transmitted from the mobile terminal 1 to the communication network 101, the burden on the communication network 101 is reduced.

  On the other hand, the time received by the mobile terminal 1 has an error. The cause of this error is mainly based on the reason that the accuracy of the clock of the mobile terminal 1 is lower than the accuracy of the atomic clock of the GPS satellite 90 and the reason that the radio wave is deteriorated by passing through the atmosphere. For this reason, it is necessary to correct an error included in the position data. For this reason, the mobile terminal 1 transmits the minimum data among the position data obtained using the distance to the positioning server 10. It is like that.

(2-4) Positioning server 10
The positioning server 10 receives the position data transmitted from the portable terminal 1, corrects an error generated in the position data, holds the corrected position data of each portable terminal 1, and stores the position data of each portable terminal 1. To come to track. In addition, the positioning server 10 receives a pseudo file transmitted from each mobile terminal 1 and holds the file.

(2-5) Communication network 101
The communication network 101 includes a wireless communication network and a wired communication network. Although not shown, the wireless communication network is, for example, a wireless base station, a base station control device, a lower exchange, an upper exchange, or the like. The wired communication network is, for example, a subscriber exchange, an upper exchange, a public network, and a gateway exchange provided at a connection point with other telephone service providers.

(2-6) Data center 19
The data center 19 holds the above balloon data and functions as a server system. The plurality of balloon data held by the data center 19 includes data of a plurality of push delivery areas A to J having attribute information (C, R) including the position C and the range R of the push delivery areas A to J, and a plurality of balloon data Each type of information provided in the push distribution areas A to J or distribution information including service information is associated with each other.

The data center 19 is connected to the communication network 101 and performs various processes or operations based on the position data transmitted from each mobile terminal 1. Specifically, the mobile terminal 1 When entering the push distribution area, a push distribution request is received and, for example, content information is distributed to the mobile terminal 1.
The data center 19 is composed of an object in a three-dimensional space (for example, a building, each floor of the building, an object that actually exists such as a signboard, or an object that moves in space) or the latitude, longitude, altitude of a desired space, and a balloon diameter described later. A data center 19 is provided to hold or manage balloon data associated with the three-dimensional space range information (three-dimensional space occupation information or space region information).

FIG. 7 is a configuration diagram of the data center 19 according to an embodiment of the present invention. An example in which one server system having the following units constitutes the data center 19 will be described. Note that the functions of the data center 19 can be distributed over the communication network 101.
The data center 19 shown in FIG. 7 includes a plurality of push delivery areas A to J having attribute information (C, R) including the center position C and radius R of the spherical push delivery areas A to J, and the push delivery area. It holds a plurality of balloon data associated with each of a plurality of distribution information including various information or service information provided by A to J. Here, the various types of information are facility information related to buildings, such as store information in buildings, Tokyo Tower and those buildings, and public transport station information. The service information is information related to the facility information, for example, company product information of the corporate building, opening information of the Tokyo Tower, menus of restaurants and restaurants in the building, and station timetable information. . In the following description, these are used in the same meaning unless otherwise specified.

The data center 19 can communicate with a portable terminal (not shown) 1. The portable terminal 1 measures the self-position, movement direction, and movement amount in the spherical push distribution areas A to J using a GPS satellite, a direction sensor, and a gyro sensor, respectively, and transmits data via the data center 19 and the communication network 101. Send and receive.
The data center 19 includes a process receiving unit (server receiving unit) 19a, a distribution area data holding unit (three-dimensional spatial range data holding unit) 19b, and a distribution information holding unit (database or distribution information holding unit for each area) 19c. And a distributed information holding unit (distributed information holding unit) 19d, an information filter 19e, a calculating unit 19f, and a providing unit (transmitting unit or server transmitting unit) 19g.

  Here, the process reception unit 19a includes the actual measurement start position L1 specified based on the latitude, longitude, altitude, azimuth, and tilt angle of the mobile terminal 1 itself transmitted from the mobile terminal 1, and the movement direction of the mobile terminal 1 itself. And movement information including the movement amount. In addition, the process reception unit 19a is connected to the communication network 101 and receives a push distribution request message transmitted from the mobile terminal 1 when entering the push distribution area, and transmits data to each mobile terminal 1 Part 19g.

The providing unit 19g receives the attribute information selected by the portable terminal 1 from the one or more attribute information transmitted from the providing unit 19g itself, and sends the distribution information of the balloon data corresponding to the attribute information to the portable terminal 1. It is to provide.
The providing unit 19g also includes one or a plurality of push distributions existing around the actual measurement start point position L1 based on self-predicted positions (L1-a, L1-b, L1-c) calculated by the calculation unit 19f described later. The attribute information of the areas A to J is transmitted to the mobile terminal 1. This function is realized by cooperation of an optical fiber, an optical transmission / reception unit, or an electrical-optical mutual conversion unit (not shown).

  The distribution area data holding unit 19b holds the position C and the range R of the plurality of three-dimensional space ranges and the type of distribution information in association with each other, and specifically identifies the distribution area. The distribution area ID for this and the attribute information (C, R) that the distribution area has are stored in association with each other. The attribute information (C, R) is, for example, distribution area position information indicating the center position of the distribution area. Note that this function is realized by an information recording medium such as a hard disk.

  Therefore, this push distribution service providing system 200 represents information related to the ranges of the plurality of push distribution areas A to J (push distribution space range information. For example, push distribution) in the distribution system that distributes information to the mobile terminal 1. Each of the attribute information (C, R) including the position C and the range R of the areas A to J) and distribution information including various information or service information provided in each push distribution area A to J. Based on the distribution information holding unit (database) 19c that holds a plurality of associated balloon data and the position information transmitted from the mobile terminal 1, one of the information about the ranges of the plurality of push distribution areas A to J The provision part (transmission part or server transmission part) 19g which transmits one or more to the portable terminal 1 is comprised.

As a result, the number of positioning operations can be reduced, the load on the communication network 101 and the positioning server 10 can be reduced, and the packet charge can be reduced.
FIG. 8A is a diagram showing an example of a distribution area data format according to an embodiment of the present invention, and shows a data format when stored in a server or the like. In addition to the distribution area ID and distribution area position information, the distribution area data shown in FIG. 8A includes a distribution area radius (radius) representing the range of the area and information contents such as restaurant information and time service information. Various attribute data of the information category data representing the type and the distribution data head address representing the held location are associated with each other. As a result, the user can register in advance how much detailed data is necessary for the information relating to the distribution area desired to be distributed to the data center 19 using the portable terminal 1.

  The information category data is also used for filtering for selecting information, and the selection avoids the burden of searching 10,000 pieces of data every time there is an access. This data is also used for changing the radius. Thereby, unnecessary data is not transmitted / received between the portable terminal 1 and the data center 19, and the processing load of the communication network 101 is greatly reduced.

  And the delivery information holding | maintenance part 19c shown in FIG. 7 hold | maintains the delivery information of several 3D space range. Specifically, it holds distribution information (contents) for each area, and functions as a database that holds balloon data. For example, as shown in FIG. 8B, this distribution information is held in association with a distribution area ID and distribution data (content itself) as N (N represents an integer) type of distribution data. Thereby, when the data center 19 receives the push delivery request transmitted when entering the push delivery area from the mobile terminal 1, the data center 19 extracts the delivery area ID included in the request message and corresponds to the extracted ID. The content is read from the distribution information holding unit 19c and transmitted to the portable terminal 1.

That is, the distribution information holding unit 19c includes data of a plurality of push distribution areas A to J having attribute information (C, R) including the center position C and the radius R of the push distribution areas A to J, and the push distribution areas A to A plurality of pieces of balloon data associated with each of a plurality of pieces of distribution information including various information or service information provided by J are held.
Here, the processing receiving unit 19a, the providing unit 19g, and the distribution information holding unit 19c cooperate to function as a notification unit. And this notification part (19a, 19c) receives the measurement starting point position L1 specified based on the latitude, longitude, altitude, azimuth | direction, and inclination angle of the portable terminal 1 itself transmitted from the portable terminal 1, and the measurement starting point The data of one or more push delivery areas A to J belonging to the radius R centered at the position L1 is extracted from the delivery information holding unit 19c, and the center position of the extracted data of one or more push delivery areas A to J is extracted. One or more pieces of attribute information (C, R) including C and radius R are notified to the mobile terminal 1.

  Further, the notification units (19a, 19c) are configured to adjust the range of the pre-read position information within a predetermined number according to the number of the three-dimensional space range data. When the shape of the three-dimensional space is other than a sphere or a circle, the notification unit (19a, 19c) can define the three-dimensional space range using a distance other than the radius. Specifically, the notification unit (19a, 19c) uses a long axis when the spatial shape is an elliptical sphere, and one or a plurality of three-dimensional points within the distance of the long axis from the actual measurement starting point position L1 of the mobile terminal 1 The spatial range data is extracted from the database, and the extracted one or more attribute information (C, R) is notified to the mobile terminal 1. Furthermore, when the space shape is a cube, the notification unit (19a, 19c) can set the distance of half of one side of each surface constituting the six surfaces of the cube and the distance of half of the opposite side of each surface to a three-dimensional space. It can be defined as a range.

Thereby, when the data center 19 receives the position information from the mobile terminal 1, the data center 19 extracts the push distribution areas A to J within the distance registered in advance by the user from the position information, and the extracted push distribution area E, for example, Is transmitted to the portable terminal 1.
Then, in the mobile terminal 1 notified of the attribute information (C, R) from the notification unit (19a, 19c), the actual measurement end position L2 of the mobile terminal 1 itself uses the actual measurement start point position L1, the movement direction, and the movement amount. Is calculated. The measured end point position L2 is one of a plurality of three-dimensional space ranges having the position C and the range R included in the attribute information (C, R) notified from the notification unit (19a, 19c) of the data center 19. If the mobile terminal 1 is determined to belong to the mobile terminal 1, distribution information of one or more balloon data corresponding to the determined one or more attribute information (C, R) is provided to the portable terminal 1.

Accordingly, it is possible to prevent data from being frequently transmitted and received between the portable terminal 1 and the data center 19 as in the prior art, and to increase the speed of data transmission / reception.
Further, the distributed information holding unit 19d shown in FIGS. 7 and 8C includes a user ID of the mobile terminal 1, a plurality of distribution area IDs (an identifier of a three-dimensional space range), and a distributed area ID (of the mobile terminal 1). Information indicating information transmitted / information not transmitted regarding the identifier) is stored in association with each other. The reason for holding whether or not it has already been distributed is to avoid the same portable terminal 1 receiving the same distribution information redundantly. Each mobile terminal 1 may return to the push delivery area once passed by movement. In this case, the distribution of overlapping information is prevented by maintaining a history of entering and exiting the same push distribution area A to J for each mobile terminal 1. Further, when the mobile terminal 1 is on the boundary line between the two areas, the distribution information can be temporarily cached in both areas. Further details will be described with reference to FIG.

  FIG. 8C is a diagram showing an example of distributed information data according to an embodiment of the present invention, and the distributed information data 001 to 111 shown in FIG. 8C includes a unique user ID [ 001] to [111] are held corresponding to the portable terminals 1 and are managed accordingly. For example, the mobile terminal 1 with the user ID [001] is provided with columns of distributed area ID (1), ID (2),..., ID (N), and the process reception unit 19a distributes to these columns. The flag indicating completed / undelivered is read and written, and management is performed so that information once pushed and delivered is not delivered to the mobile terminal 1 a plurality of times. This prevents the user from displaying the same information many times. The distributed information can also be cleared. For example, when cleared at midnight or in the early morning, the information can be distributed again to the same portable terminal 1 during the day.

Further, the information filter 19e shown in FIG. 7 selectively outputs a large number of information such as the distribution area data, distribution information (contents), distributed information, etc. based on a user intention or an advertising policy by a company or a store in advance. Is.
FIG. 24 is a diagram for explaining filtering of distribution information (content) according to an embodiment of the present invention. In the distribution information shown in FIG. 24, layers are assigned to information categories such as restaurants, time services, recommended spots,..., Toy stores, and children's clothes. And since the information filter 19e selects the desired layer of many layers based on a user's hope or the business object of a company and a store, and transmits the information registered in the selected layer to a user. is there. That is, the data center 19 filters information by changing and controlling the position or radius of each information balloon. For example, the data center 19 can distribute the number of contents according to the memory capacity of the mobile terminal 1, and in addition, if the number of contents is limited according to the contract fee of the user, the amount of information to be transmitted is limited. it can.

  Accordingly, the providing unit 19g illustrated in FIG. 7 includes one or more pieces of attribute information selected by the mobile terminal 1 from the attribute information (C, R) notified to the mobile terminal 1 by the notification unit (19a, 19c). (C, R) and the self-predicted position (L1-a, L1-b, L1-c) predicted by the mobile terminal 1 itself calculated using the movement information including the moving direction and the moving amount of the mobile terminal 1 Based on the above, whether the mobile terminal 1 belongs to the three-dimensional space range is predicted. When it is determined that the mobile terminal 1 belongs to the three-dimensional space range, the process reception unit 19a confirms that the mobile terminal 1 belongs to the three-dimensional space range by comparing the correction position obtained by correcting the actual measurement end position L2 with the three-dimensional space range. Based on the confirmation result, distribution information of balloon data corresponding to the distribution information is provided to the mobile terminal 1.

  When the mobile terminal 1 is notified of the attribute information (C, R) from the notification unit (19a, 19c) of the data center 19, the mobile terminal 1 transmits the latitude of the mobile terminal 1 itself transmitted from the mobile terminal 1. , The actual measurement end point position L2 of the mobile terminal 1 calculated using the actual measurement start point position L1 specified based on the longitude, altitude, azimuth, and tilt angle and the movement direction and amount of movement measured by the mobile terminal 1 itself, When belonging to push distribution areas A to J existing in a sphere (or in a circle) having a radius R centered on the center position C of the attribute information (C, R) notified from the notification unit (19a, 19c), Distribution information of balloon data corresponding to one or more attribute information (C, R) determined to belong is provided to the mobile terminal 1.

  In other words, the notification unit (19a, 19c) receives the actual measurement start point position L1, and stores distribution data of one or more push distribution areas A to J belonging to the radius R with the actual measurement start point position L1 as the central point. The mobile terminal 1 is notified of one or more pieces of attribute information (C, R) including the center position C and the radius R of the extracted data of the one or more push delivery areas A to J extracted from the unit 19c. In the mobile terminal 1, the mobile terminal 1 is based on one or a plurality of attribute information (C, R) selected from the attribute information (C, R) notified from the data center 19 and the self-predicted position. Predicts whether or not it belongs to its own push distribution areas A to J, and if it is determined that it belongs to these areas A to J, measures the measured end point position L2, and transmits this measured end point position L2 to the data center 19. To do.

Further, the data center 19 confirms that the mobile terminal 1 itself belongs to the push delivery areas A to J by comparing the correction position obtained by correcting the actual measurement end position L2 with the push delivery areas A to J, and the confirmation result is as follows. Based on this, various information of balloon data corresponding to the distribution information or service information is provided to the portable terminal 1.
Accordingly, since the company or the store can manage the users by grouping them, information with high added value can be provided to the users. In addition, since information is layer-managed, the data center 19 can adaptively change the amount of information transmitted to the mobile terminal 1. In addition, the company or the store can set each distribution area independently, and can perform information mail distribution by selecting a specific user in advance by user group management.

Further, when the push delivery area has a circle shape (including both when a sphere is projected onto a plane or when the push delivery plane is managed with a circle), the push delivery area that the data center 19 notifies the mobile terminal 1 of. The upper limit of the number is provided, and the radius of the prefetch area according to the number of the push delivery areas A to J is determined.
FIGS. 9A and 9B are diagrams for explaining the change of the radius of the prefetch area according to the embodiment of the present invention. In the city 150 shown in FIG. 9A, a large number of push distribution areas (solid circles) are displayed, and the location marked with “x” is the position of the mobile terminal 1. With the position of the portable terminal 1 as the center, a prefetch area with a radius r1 and a prefetch area with a radius r2 (r1> r2) are displayed by dotted lines. The relationship shown in FIG. 9 (b) shows the correspondence between the radius of the prefetch area and the number of distribution areas from which a circle having the radius can be read. Seven distribution areas can be read and displayed on the mobile terminal 1. Here, when the threshold value of the number of distribution areas is predetermined as 10, for example, the radius r1 is changed to the radius r2.

  The above is what is necessary for the present embodiment. The data center 19 can be provided with a calculation function for predicting the position of the mobile terminal 1, and the calculation unit 19f is used for that purpose. Here, the calculation unit 19f, based on the actual measurement starting point position L1 received by the process reception unit 19a and the movement information, the self-predicted position (L1-a, L1-b, L1-c) predicted by the mobile terminal 1 itself. Is calculated. By providing this calculation function on the communication network 101 side, the portable terminal 1 only needs to transmit only the data related to the position to the communication network 101 side, which is advantageous in power consumption.

Self-predicted position (L1-a) predicted by the mobile terminal 1 itself calculated using the attribute information (C, R) including the position C and the range R of the mobile terminal 1 and the movement information including the movement direction and amount of movement of the mobile terminal 1 itself. , L1-b, L1-c), it is determined whether the mobile terminal 1 belongs to the push delivery areas A to J. These will be described later with reference to FIG. 11, for example.

Further, the prefetch processing unit 308 will be described in detail. An example of the prefetch processing unit 308 is a dedicated JAVA (registered trademark) application for the mobile terminal 1 to receive a service from the data center 19.
The function of the prefetch processing unit 308 is realized by an application for performing processing for obtaining the actually measured end point position L2 of the mobile terminal 1, and is activated when the user presses a key (input / output unit 307) manually. It has become so. The prefetch processing unit 308 includes a prefetch flag (prefetch flag holding unit) 308a indicating whether prefetching is necessary / unnecessary. The prefetch flag 308a is provided in a RAM or the like. For example, the bit is 1 when prefetching is necessary, and the bit is 0 when prefetching is unnecessary, so that the prefetching flag 308a can be identified. In other words, when the prefetch processing unit 308 reads the prefetch flag ON (ON), the main control unit 302 newly requests actual measurement, whereby the main control unit 302 performs positioning with respect to the positioning unit 301. To make it happen.

  Furthermore, the content category setting unit 309 is an application for registering in advance in the data center 19 the category or type of content that the user desires to distribute. This registration means that a user selects a content category desired to be distributed from a very large number of contents of the data center 19. That is to say, it is possible to filter out what the user needs among service types such as store types such as restaurants and toy stores, and low-priced products, time services, and recommended products.

Note that the functions of the prefetch processing unit 308 and the content category setting unit 309 are all realized by the CPU 302, the input / output unit 307, the ROM, the RAM, and the like, for example. Note that these functions may be provided in the data center 19 and may be automatically activated when the terminal is turned on.
Thus, the transmission / reception function is realized mainly by the cooperation of the transmission / reception antenna 300b, the communication unit 304, the CPU 302, and the input / output unit 307.

The positioning antenna 300a receives radio waves transmitted from a plurality of GPS satellites 90.
The positioning unit 301 acquires position information using the GPS satellite 90. This positioning unit 301 measures each of the actual measurement start point position L1 and actual measurement end point position L2 of the mobile terminal 1 and the movement information including the movement direction and the movement amount of the mobile terminal 1 itself in the three-dimensional space range. Specifically, the positioning unit 301 measures latitude, longitude, altitude, azimuth, and tilt angle, and extracts position data representing an actual position from the received data. The position data is written in the recording unit 303 for holding the data by the CPU 302 and read out to the communication unit 304 at a predetermined interval.

Further, the gyro sensor unit 305 integrates and outputs data related to the tilt angle of the mobile terminal 1 and detects angular velocity. By integrating the output of the gyro sensor unit 305 with time, the amount of movement of the mobile terminal 1 from the time when the mobile terminal 1 of the mobile terminal 1 starts to measure the tilt angle to the present can be obtained. .
The azimuth sensor / tilt sensor unit 306 is a sensor having both functions of an azimuth sensor that measures the azimuth and a tilt sensor that measures the tilt angle from the horizon. By this azimuth sensor, the moving direction (azimuth or direction) of the mobile terminal 1 is calculated using geomagnetism, and the tilt angle of the mobile terminal 1 is calculated using the acceleration sensor by the tilt center. In addition, information regarding the state (position, azimuth, tilt angle, roll angle, pitch angle) where the mobile terminal 1 is placed is calculated by the CPU 302, and how much distance the mobile terminal 1 is in which direction. You can get information on how you moved. The calculation result is displayed by the input / output unit 307 and recorded in the recording unit 303.

In addition to the CPU 302 and the input / output unit 307, the positioning antenna 300a, the positioning unit 301, the recording unit 303, the gyro sensor unit (3D gyro sensor unit) 305, the azimuth sensor unit 306, and the input / output unit 307 mainly cooperate. By doing so, the positioning function is realized, the moving direction and the moving amount can be obtained, and the mobile terminal 1 can recognize the actually measured position.
Therefore, the mobile terminal 1 includes a GPS processing positioning unit 301, an orientation sensor 306, an inclination sensor 304, a prediction unit that predicts its own position using the mobile terminal 1 equipped with the three-dimensional gyro sensor 305, and a plurality of push distribution areas. It will have the acquisition means which acquires the range information which AJ occupies, and the comparison means which compares several push delivery area AJ and a self-position.

  Therefore, the mobile terminal 1 receives information from the push distribution service providing system 200 that distributes information. Based on the location information of the mobile terminal 1, the mobile terminal 1 receives a plurality of information received from the push distribution service providing system 200. The main part which requests | requires delivery to the push delivery service provision system 200, if it detects that the recording part 303 which records push delivery area AJ and the own portable terminal 1 exist in the three-dimensional space which push delivery area AJ shows. The control unit 302 is configured.

Thereby, the frequency | count of positioning reduces and content push delivery, such as a store advertisement, becomes possible pinpoint.
As described above, the mobile terminal 1 can automatically obtain the advertisement information from the plurality of push delivery areas A to J of the push delivery service providing system 200 by the cooperation of the transmission / reception function and the positioning function.

(2-8) Look-ahead area 100
A prefetch area 100 is displayed separately from the plurality of push delivery areas A to J shown in FIG. The prefetch area 100 is an area for the data center 19 (server system side) to notify the mobile terminal 1 of the information on the adjacent push delivery areas A to J. Specifically, the data center 19 grasps the position of each mobile terminal 1 and notifies the mobile terminal 1 of information on push distribution areas A to J near the location where each mobile terminal 1 is currently located. .

Therefore, the data center 19 includes a notification unit (19a, 19c) for notifying the mobile terminal 1 of the positions and ranges of the plurality of push delivery areas A to J existing around the user's position, It is configured to include an adjustment unit that adjusts the range of the prefetch area according to the number of push distribution areas A to J.
(3) Description of positioning method (3-1) Conventional positioning method The mobile terminal 1 in the push distribution area E shown in FIG. 1 receives data via the physical links Q1 and Q2 from the communication network 101. Data is transmitted to and received from the center 19 or the positioning server 10. Here, the link Q1 includes a wireless link between the mobile terminal 1 and a wireless base station (not shown) and a wired link between the wireless base station and the positioning server 10. The push delivery service providing system 200 uses this link Q1 to constantly transmit the positioning data measured by the mobile terminal 1 in order to keep track of the accurate position of the mobile terminal 1 itself. It was. The mobile terminal 1 requested the data center 19 for push delivery in order to obtain push delivery.

  The link Q <b> 2 includes a wireless link between the mobile terminal 1 and the wireless base station, and a wired link between the wireless base station and the data center 19. And the portable terminal 1 transmits the positional information obtained using the GPS satellite 90 with respect to the positioning server 10, On the other hand, the positioning server 10 calculates the position of the portable terminal 1 based on the positional information, The calculation The result is transmitted to the portable terminal 1 again.

  Thereby, the mobile terminal 1 uses both the links Q1 and Q2 to receive the location information of the mobile terminal 1, the push delivery request received when entering the push delivery area from each mobile terminal 1, and its processing Information data to be delivered by push was frequently sent and received. Therefore, a large number of mobile terminals 1 in the city 150 use the communication network 101, and thus the burden on the communication network 101 is large.

(3-2) Positioning Method to which the Present Invention is Applied A method for the mobile terminal 1 to predict its own position when the mobile terminal 1 moves will be described with reference to FIG.
FIG. 11 is a diagram for explaining the reduction of the number of positioning times according to an embodiment of the present invention, and shows the city area 150 as viewed from above. The circular information distribution area G shown in FIG. 11 is an area for notifying information around the location where each mobile terminal 1 is currently present, and displays balloon data held as a three-dimensional space as a two-dimensional plane. It is. In other words, the push distribution area G is obtained by projecting and displaying balloon data of a sphere or an elliptic sphere on a two-dimensional coordinate plane (x, y). The prefetch area 100 is an area formed as the mobile terminal 1 moves. As an example, the shapes of both areas are circular, and the center positions of the prefetch area 100 and the push delivery area G are L1 and C1, respectively, and the radii of both areas are r, R1. Here, L1 and L2 are respectively measured spatial positions (measured positions) of the mobile terminal 1, and L1-a and L1-b are self-predicted positions (L1-a and L1) of the mobile terminal 1, respectively. -B, L1-c). In addition, the actual measurement starting point position L1 is outside the push delivery area G. The shape of both areas may be a rectangular shape or the like, and the center position and the distance from this center position can be variously changed according to the design policy.

  In this push distribution service providing method, the data center 19 transmits data of each push distribution area A to J determined by the positions and radii of the plurality of push distribution areas A to J to the mobile terminal 1 (transmission step), The mobile terminal 1 compares the transmitted data regarding the range of the push delivery areas A to J with the self-predicted position (L1-a, L1-b, L1-c) predicted by the mobile terminal 1 itself. 1 predicts that the mobile terminal 1 itself belongs to the push distribution areas A to J (prediction step), and if the mobile terminal 1 is determined to belong to the mobile terminal 1 based on the prediction result obtained by the prediction, the mobile terminal 1 Measures its own measured end point position L2 (positioning step). Next, the mobile terminal 1 confirms that the mobile terminal 1 itself belongs to the push delivery areas A to J by comparing the corrected delivery position obtained by measuring the measured end position L2 with the push delivery areas A to J. (Confirmation step) The mobile terminal 1 requests the distribution information associated with the push distribution areas A to J to the data center 19 based on the confirmation result (request step), and the data center 19 requests the distribution information. The distribution information is transmitted to the mobile terminal 1 based on the above (content providing step).

  As a result, the user moves from the actual measurement starting position L1 to L1-a, L1-b, L2 (L1-c) with the mobile terminal 1 and enters the push distribution area G. In this movement, the user first measures the position at the actual measurement starting point position L1. Next, when the user moves for a certain period of time, the mobile terminal 1 predicts the current position using the gyro sensor unit 305, the direction sensor unit 306, etc., starting from the actual measurement start point position L1, and obtains L1-a as the prediction result. . Further, the user moves for a certain time, predicts the self position, obtains L1-b as a prediction result, and then predicts again to obtain L1-c when moving for a certain time.

In addition, the mobile terminal 1 also performs actual measurement using the position information from the GPS satellite 90 during movement, and by using this actual measurement result together with the prediction result, the actual measurement position can be accurately known. In addition, the timing which makes this prediction can also use methods other than making every fixed time.
That is, the prefetch processing unit 308 (see FIG. 10) sets the mobile information 1 to a spherical range in which the movement information including the movement direction and the movement amount is the center position C, and the attribute information (C, R) range is the radius R. It is configured to determine whether or not its own predicted position belongs.

  Accordingly, when the user is moving in the L2 direction sequentially from L1, the mobile terminal 1 can know the movement information (movement direction and movement amount) using the gyro sensor unit 305 and the like. Further, since the mobile terminal 1 holds data (C, R) related to the push delivery area (for example, the push delivery area G), the inside / outside of the push delivery area G can be predicted.

  That is, the mobile terminal 1 predicts that the mobile terminal 1 itself is not in the push delivery area G at both points L1-a and L1-b, while push delivery at the point L1-C. Predict that it is in area G. When the mobile terminal 1 predicts that it is in the push delivery area G, it actually measures the position in order to confirm the prediction result.

As described above, the mobile terminal 1 identifies the inside or outside of the push distribution area and does not perform positioning at a point predicted to be outside the area, so that the number of positioning can be greatly reduced.
Further, as described above, since the mobile terminal 1 performs positioning at the position predicted as the information push area while predicting its own position, the load on the communication network 101 necessary for positioning and the load necessary for the positioning server are reduced. Can be reduced. In addition, the packet charge necessary for continuous positioning can be reduced, and the mobile terminal 1 can easily receive the information push delivery service. Thus, the mobile terminal 1 predicts that it belongs to the push delivery area. Moreover, since it is based on a positioning result, an exact measured position and a push delivery area can be compared. Further, the content is attached to the push distribution area, and the content is transmitted from the data center (server system) 19 side based on a request from the mobile terminal 1.

  Thus, according to the push delivery service providing system 200, the portable terminal 1 does not need to consider the inside or outside of the cell area as in the related art. Therefore, each administrator can freely design the setting contents of the push area. This also eliminates the need for special wireless protocols such as Bluetooth (registered trademark of the industry group that promotes Bluetooth technology standardization and specification development for Bluetooth-SIG [Bluetooth-Special Interest Group]). The investment amount for constructing the push delivery service providing system 200 can be reduced.

(4) Description of operation The prefetch processing of the prefetch area will be described for the push delivery service method in the present system configured as described above.
(4-1) Prefetch Processing Method by Prediction FIG. 12 is a flowchart for explaining a prefetch processing method by prediction according to an embodiment of the present invention. In step A1, the service is started when the user starts an application in the terminal. In this state, the prefetch flag is on (ON), and in the state where the application is activated, the mobile terminal 1 cannot grasp the current position. This ON means that the data in the prefetch area should be obtained from the data center 19. This application may be provided on the data center 19 side, and can be automatically started when the terminal is turned on without manually starting the application.

  For this reason, the portable terminal 1 measures the position with the positioning server 10 to acquire the current position (step A2), and transmits the positioning result to the positioning server 10. The positioning server 10 corrects the position of the positioning result (step A3) and transmits the corrected position information to the mobile terminal 1. Here, as shown in FIG. 13, for example, the position information transmission / reception data format includes a header including a destination and measured position information in both the positioning result and the position information.

  In step A4, the mobile terminal 1 checks whether or not the prefetch area update flag is on. Here, since the value of the prefetch flag is on in step A <b> 1, the mobile terminal 1 obtains prefetch area data from the data center 19. A method for obtaining this data is as follows: a prefetch distribution area update request is transmitted from the portable terminal 1 to the data center 19, the distribution center data is searched for in the data center 19 (search process SR), and the prefetched distribution area searched for Data is notified from the data center 19 to the portable terminal 1. Note that the data format of the prefetch distribution area update request has a header (including a destination and a prefetch area update order identifier) and measured position information, for example, as shown in FIG.

  As for details of the search processing SR in the data center 19, for example, as shown in FIG. 15, the data center 19 searches the number of distribution areas belonging to the radius R (step SR1), and as shown in FIG. The amount of information is reduced by filtering. Specifically, when the number of distribution areas is larger than a preset threshold value, the route is attached with (distribution area number> threshold), and the value of radius R is decreased (step SR2). continue processing. In step SR1, when the number of distribution areas is a threshold value, the pre-read distribution area data is notified to the portable terminal 1 through a route labeled (number of distribution areas ≦ threshold value). Thereby, each radius of push delivery area AJ is adjusted to a desired magnitude | size.

  This prefetch area data is data related to the push delivery area belonging to the radius of the prefetch area with radius R from the actual measurement position. When there are a plurality of push delivery areas, for example, as shown in FIG. In addition to the notification order identifier and the radius of the look-ahead area, a set of three types of elements including a distribution area ID (Identification), position information at the center of the distribution area (distribution area position information), and a distribution area radius. Multiple data are transmitted.

  In step A5 shown in FIG. 12, the mobile terminal 1 turns off the prefetch flag. Furthermore, the portable terminal 1 starts a timer (not shown) and checks whether or not it is in the push distribution area by actual measurement within a predetermined time (step A6). When the mobile terminal 1 is in the area, the push distribution request is transmitted to the data center 19 through the Yes route.

FIG. 16 is a diagram showing an example of a data format for push distribution request / distribution / reception completion notification. The data format for a push delivery request has a header (destination, push delivery request order identifier), a user ID, and a delivery area ID.
On the other hand, in FIG. 12, upon receiving this request, the data center 19 checks whether or not the received data is the information desired to be distributed based on the history information registered in advance (step A7). In the case of the information desired to be distributed, the information (content) registered in the area is distributed to the mobile terminal 1 through the Yes route (step A8). This content distribution data format has, for example, a header (destination, content distribution order identifier) and content data as shown in FIG. Then, in FIG. 12, when the mobile terminal 1 receives this content, a reception completion notification is transmitted to the data center 19. The data format for this reception completion notification includes, for example, a header (destination, reception completion notification order identifier, distribution area ID), a user ID, and a distribution area ID as shown in FIG.

  In FIG. 12, upon receiving this notification, the data center 19 writes “distributed” as the distributed area ID (see FIG. 8C) of the area where the mobile terminal 1 is currently located (step A9). This prevents the distributed information from being redistributed when the mobile terminal 1 leaves the current area where it is present and moves to another area and then returns to the current area. In step A7, if it is not the information desired to be distributed, the route No is passed and the data center 19 does not distribute the information. In Step A6, if the mobile terminal 1 determines that it is outside the push distribution area, it passes the No route.

  Subsequently, in step A10, the mobile terminal 1 calculates its current position based on gyro sensor information, direction sensor information, and measured position information at regular intervals, and performs the following three types of checks. . That is, the mobile terminal 1 checks whether or not the self-predicted position (L1-a, L1-b, L1-c) belongs to the prefetch area using the calculated result (step A11). Then, the No route is passed, the prefetch area update flag is turned on (step A14), and the processing from step A1 is executed.

  In addition, when the self-predicted position (L1-a, L1-b, L1-c) belongs to the prefetch area in step A11, the mobile terminal 1 passes through the Yes route and further passes the self-predicted position (L1-a, It is checked whether or not L1-b and L1-c) belong to the distribution area (step A12). Here, if the self-predicted position (L1-a, L1-b, L1-c) does not exist in the distribution area, the mobile terminal 1 performs the process of step A1 through the No route. On the other hand, if the self-predicted position (L1-a, L1-b, L1-c) is present in step A12, the portable terminal 1 passes through the Yes route and the distribution area is a distributed area ID (FIG. 8). (See (c)) is checked (step A13). If it has been distributed, it passes through the Yes route, and returns to the process in step A10. Execute the process.

In this way, the mobile terminal 1 can pre-read the push distribution areas A to J and manage whether each mobile terminal 1 has been distributed for each area, so that redundant information is not distributed.
Further, in steps A7 and A8, the data center 19 has previously registered contents desired to be distributed from the user. This registration method will be described with reference to FIG.

(4-2) Registration Method of Distribution Desired Information FIG. 17 is a flowchart for explaining content category registration processing according to an embodiment of the present invention. In step C <b> 1 shown in FIG. 17, when the mobile terminal 1 activates the content category (distribution information category) setting unit 309, the mobile terminal 1 requests the data center 19 to transmit a distribution information category list. When the data center 19 receives this request, it performs predetermined processing and transmits a distribution information category list to the portable terminal 1. When the user selects an information category to be distributed from the list (step C2), the mobile terminal 1 transmits a distribution information category registration request to the data center 19, and the data center 19 registers the distribution category (step S2). C3), the distribution information category registration completion is notified to the portable terminal 1.

Thus, since the user can register the content of the desired content in the data center 19 in advance, the company or the store can provide a highly effective advertisement to the user.
Next, a method in which the mobile terminal 1 pre-reads the distribution area position by actual measurement will be described with reference to FIG.
(4-3) Prefetch Processing Method by Actual Measurement FIG. 18 is a flowchart for explaining a prefetch processing method by actual measurement according to an embodiment of the present invention.

  When the portable terminal 1 starts an application in the terminal (step B1), the service is started. Here, the prefetch flag is on, which means that data in the prefetch area should be obtained from the data center 19. For this reason, the portable terminal 1 requests the positioning server 10 to transmit positioning support information. When the positioning server 10 receives this request, the portable terminal 1 performs processing (step B1y), and sends the positioning support information to the portable terminal 1. Send.

  The mobile terminal 1 performs positioning (step B2), checks whether the prefetch area update flag is on (step B3), and if the prefetch flag value is on, passes the Yes route, 19 is notified of prefetch distribution area data. As a method of notifying this data, when a prefetch distribution area update request is transmitted from the portable terminal 1 to the data center 19, the data center 19 searches for distribution area data within the radius r from the actually measured position (see FIG. Search processing SR shown in FIG. 15), the searched prefetch distribution area data is notified to the portable terminal 1. When receiving the prefetch distribution area data, the portable terminal 1 turns off the prefetch flag (step B4). The data format of the prefetch distribution area update request is the same as the format shown in FIG.

  On the other hand, when the value of the prefetch flag is OFF in step B3, the mobile terminal 1 passes through the No route, and checks whether the user is in the distribution area (step B5), and the mobile terminal 1 is in the area. Sends a push delivery request to the data center 19 through the Yes route. Upon receiving this request, the data center 19 checks whether or not the received data is information desired to be distributed (step B6). If the received data is information desired to be distributed, the data center 19 passes through the Yes route to the area. Is distributed to the mobile terminal 1 (step B7), and when the mobile terminal 1 receives this information, a reception completion notification is transmitted to the data center 19, and the data center 19 When this notification is received, a distributed area ID (see FIG. 8C) representing the area is written as distributed (step B8). In step B6, if the information is not desired to be distributed, the route is No and the data center 19 does not distribute the information.

  In step B5, if the user is outside the distribution area, the route passes No route, and the mobile terminal 1 checks whether or not the actually measured position belongs to the prefetch area (step B9). Here, if it exists, it passes through the Yes route, and the process of step B2 is performed. If it does not exist, it passes through the No route, and in step B10, the portable terminal 1 turns on the prefetch area update flag. .

Accordingly, the mobile terminal 1 can pre-read by actually measuring the distribution area position.
As described above, the mobile terminal 1 uses the GPS satellite 90, the direction sensor / tilt sensor unit 306, and the gyro sensor unit 305 to determine the state in which it is placed (position, direction, tilt angle, roll angle, pitch angle). ), It is possible to know how much it has moved in which direction. Then, the push delivery service providing system 200 downloads information related to a plurality of push delivery areas A to J existing around the terminal from the data center 19 side in advance to the terminal side, and periodically compares it with its own predicted position. . Thereby, the user can predict whether or not the terminal is in the push distribution area.

  Further, when it is predicted that the mobile terminal 1 is in the push distribution area, the mobile terminal 1 measures itself and thereby can perform accurate position confirmation. On the other hand, when the mobile terminal 1 is in the push distribution area, the mobile terminal 1 transmits a content transmission request to the positioning server 10, and the positioning server 10 refers to the transmission enable / disable setting information related to the transmitted user. The positioning server 10 distributes the content accompanying the area to the terminal only when the setting information can be distributed.

The above description is about the case where the prefetch area is in contact with one push distribution area.
Next, the case where the prefetch area is in contact with a plurality of push delivery areas A to J will be described with reference to FIGS.
(4-4) When there are a plurality of prefetch areas FIGS. 19A and 19B are diagrams for explaining the operation when the prefetch area is in contact with a plurality of push delivery areas A to J, respectively. In the city area 150 shown in FIG. 19A, a plurality of push delivery areas A to G, J are displayed, and the mobile terminal 1 moves in the order of positions L1, L2, L3 shown in FIG. 19A. ing. FIG. 19B shows the correspondence between the actual measurement position, the prefetch area, and the push delivery content. Here, the prefetch area when the position of the mobile terminal 1 is L1 is in contact with the push delivery areas A and B, and the prefetch area when L2 is in contact with the push delivery areas C, F, and J. Then, when the mobile terminal 1 comes to L3, the prefetch processing unit 308 of the mobile terminal 1 considers itself to be in the push delivery area J. In this case, it is determined that the prefetch area is unnecessary. As described above, even when the prefetch area is in contact with a plurality of push delivery areas A to J, the mobile terminal 1 can obtain an accurate push delivery area, and the communication network 101 transmits and receives a large amount of data. Therefore, the burden on the communication network 101 is greatly reduced. Furthermore, communication speed can be increased by reducing the amount of data.

As described above, according to the present invention, the number of times of measurement of the actually measured position is reduced, and the user can pinpoint store information limited to the position where the user is present. In addition, the company can pinpoint limited store information near the location where the user is located to the user.
(5) Description of an Example of the Effect of the Present Invention Hereinafter, an example of achieving efficiency when the push delivery service providing system 200 is used will be described. In addition, a numerical value represents an example and this invention is not limited to these numerical values.

(5-1) Number of balloon data that can be stored in the memory of the mobile phone Balloon data number = (memory capacity of JAVA data part) ÷ (data amount of one balloon) = 1000 Here, the JAVA data part is the above-mentioned JAVA application. The JAVA data part has a memory capacity of 100 KB (kilobytes), and the data amount of one balloon is estimated to be 100 bytes, which is rather large. JAVA is the above registered trademark.

(5-2) Number of balloons on one side of an area occupied by 1000 balloons Number = square root of 1000 = about 31 (pieces)
(5-3) Distance of one side of each area (m)
Distance = 31 (pieces) * (diameter of one balloon) = 1550 (m)
Here, * represents multiplication, and the diameter of one balloon is 50 m (value used in the proto experiment).

(5-4) Time required for the user to walk straight on one side of the area Time = 1550 * 60 ÷ (human walking speed) = 23.25 (minutes)
Here, the human walking speed was set to 4000 m / hour.
(5-5) Number of times of access to network (communication network 101) Conventionally, 23 minutes / (network access frequency) = 23 times, and this time is one time access. Here, the network access frequency is assumed to be 1 time / minute.

Therefore, the efficiency can be reduced to 1/23 by the calculation of (5-1) to (5-5).
(6) Description of Modifications The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
(6-1) Service for transmitting information via a plurality of balloons The push delivery service providing system 200 can also transmit information via a plurality of balloons as another form of service. When one balloon information is updated between adjacent or neighboring balloons of a plurality of balloons or between linked balloons, the update is performed on other balloons in the same manner. .

(6-1-1) Example of Linking Balloon Updates Between Stores When the head office and a plurality of branches or chain stores are registered with balloons, when the head office updates information on each branch, By updating one main store balloon, all other branch or chain store balloons are updated in conjunction. Thereby, the identity of the data of each store is maintained by a simple operation.

Each store balloon can be updated in conjunction with sales information for each region. For example, balloons can be registered for each branch in Tokyo, Osaka, and New York, and these balloons can be updated.
(6-1-2) Traffic Information Notification Service The push delivery service providing system 200 registers balloons representing traffic information for each predetermined distance or service area on the expressway, and each balloon linked by this registration is registered. This information is updated, and the user can obtain the degree of congestion of the vehicle and weather information.

In addition, when a truck that transports dangerous goods enters the road, safety information (for example, the name of the neutralizing agent) regarding the dangerous goods is registered in the balloon.

(7) Method of providing a virtual three-dimensional space Explanation of a service on how to allocate a balloon to a user (company, store, etc.) who puts information on a balloon constructed by the push delivery service providing system 200 and increase profits To do. For example, a virtual space corresponding to a real space (real space) (representing a space corresponding to a set of three-dimensional space information of balloons stored in a server) is divided into meshes and displayed on the homepage of the push delivery service providing system 200 To sell virtual space. The user accesses the home page via the Internet and selects a desired virtual space from a plurality of divided virtual spaces corresponding to the real space.

  As a result, a fee for posting advertisements, etc. is displayed in the virtual space selected by the user (this is a balloon and has predetermined three-dimensional space information). The divided virtual space can be used by the user. That is, it is possible to set a link between a predetermined three-dimensional space and a URL (Uniform Resource Locator) where advertisements are posted. The setting method for registration of the information is described in detail in Japanese Patent Application No. 2000-318537 (patent application date: October 18, 2000) by the same applicant.

  The above fee setting can be arbitrarily set by the push distribution service providing system 200 or a service provider providing the spatial information providing system as disclosed in the patent application, or linked to the land price of the real space. It can also be made. For example, land price information per square meter in real space is made into a table in correspondence with real three-dimensional space information (latitude, longitude). Further, a basic fee for posting advertisements, etc. is determined, and the latitude and longitude information of the real space corresponding to the latitude and longitude information of the selected virtual space desired by the user is determined based on the land price information of the table. By increasing or decreasing the basic fee, it is possible to set the fee for the virtual section corresponding to the land price information.

  Therefore, this virtual three-dimensional space providing method stores virtual three-dimensional space information corresponding to a real three-dimensional space in association with information provided by a user such as a company or a store or related information of the provided information. This is a method for providing the virtual three-dimensional space in the push delivery service providing system 200 that provides relevant information to the customer user from the location information of the customer user who desires to provide information. Here, the administrator divides this virtual three-dimensional space information into a plurality of virtual three-dimensional space information in advance, and at least one virtual corresponding to a real three-dimensional space desired by a user such as a company or a store that wants to provide information. A three-dimensional space is selected from a plurality of divided virtual three-dimensional space information, and a charge corresponding to the selected virtual three-dimensional space is presented.

Thereby, since the range of the virtual three-dimensional space information can be made variable, the range can be reduced in the city center, the range can be set larger in the suburbs, and the density of service contents can be changed according to the service area.
Specifically, the land price information at point A in the real space is A yen, the land price information at point B is B yen, the basic charge for using virtual space information is C yen, and the corresponding land price of the real space is D yen. And When the user selects the virtual space corresponding to the real space A point, the charge is
Charge = C x A / D (x and / represent multiplication and division, respectively)
The usage fee of the virtual space selected by the user is automatically obtained by the above table and calculation. Note that the above calculation method is an example, and it is possible to flexibly cope with such factors as multiplying the calculated fee by a factor of 0.9 when the fee increases to some extent, or multiplying by a factor of 1.1 when the fee decreases to some extent. .

Although the virtual space sales service for users to post information in the virtual space has been described, the above is an example, and the method and fee setting via the Internet are one embodiment and are not limited to this. .
