Description

Specification

Information provision service system, user terminal in the system, spatial information server in the system, and service information provision method in the system

The present invention relates to an information providing service system, a user terminal in the system, a spatial information server in the system, and a service information providing method in the system, which are suitable for an information distribution service using a mobile terminal, for example.

Background art

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 whether a mobile device is turned on or off, or whether the mobile device is connected to a network or not, from a server system (a plurality of servers that combine multiple servers with multiple functions) to a mobile device. When information is distributed, the mobile terminal automatically receives the information. This information includes, for example, restaurant menus, bargains at various stores, business hours, etc., news, maps, information on public facilities, corporate advertisements, etc. This means that the server system sends a wide variety of information to users (customers).

[0003] Then, similar to the reception of mail (e-mail) in the standby state of the mobile phone, when the mobile terminal receives information on the server system power, the mobile terminal notifies the user by a ring tone or the like, and the user notifies the information. You know what has been done. Therefore, by using this method, the user can obtain information without connecting to the network by himself / herself, but can receive information in real time. This method is called that the server system pushes information (PUSH) to the user. On the other hand, a method in which a user obtains information by connecting to the network by himself / herself is called that the user pulls information (PULL) in the server system.

[0004] In addition, a provider (hereinafter referred to as an administrator) that provides a push distribution service measures the terminal position of a mobile terminal (hereinafter referred to as “Positioning”) using various technologies. Has introduced a method. For example, GPS (Global Positioning System), IC (Integrated Circuit) tag, wireless LAN (Local Area Network) or station ticket gate machine etc. A device can be installed at a specific location as an access point device, or a measurement method defined by a wireless communication protocol (eg Bluetooth) can be used. As an example, when each device detects that a mobile terminal is in front of a specific building, each device sends the detection result to the server system. On the other hand, the server system has already entered the building and stores service information such as restaurant menus in a database (saved, stored, accumulated, recorded, stored) and included in the detection results of mobile terminals. The database is searched using the location information as a search tag, and the menus obtained by the search are notified to the mobile terminal.

[0005] By the way, when the server system provides information such as store advertisements to mobile terminals in a specific area, various devices such as IC tags and wireless LANs access the server system from the mobile terminals. In addition, it is necessary to install access point equipment in advance and to construct a network as the background of the system including the server system.

Furthermore, when a store sends information such as advertisements of the store itself, the store provides information to the manager or the server system of the manager in accordance with a method determined by the manager. On the other hand, the administrator usually collects an advertising fee from the store as an advertising fee.

[0006] In addition to such push distribution services, various information providing services have been proposed in the past.

The guidance information presentation device described in Patent Document 1 provides guidance information such as routes, and provides various route information such as recommended sightseeing courses and date courses, as well as additional information thereof, on networks and electronic media. To deliver through. This will provide a route guidance service that anyone can use anytime and anywhere.

[0007] The mobile object discovery Z guidance information providing system described in Patent Document 2 is generally used to identify identification information unique to a mobile object from among an unspecified number of mobile objects such as humans, animals, and objects that move outdoors. By using such attribute information, a mobile object having a desired attribute is discovered and guidance information for approaching the discovered mobile object is provided. This allows the user to specify It is possible to provide guidance information that satisfies the discovery conditions.

[0008] The information providing service system described in Patent Document 3 includes a database that holds data in which spatial range information in a three-dimensional space and search information for obtaining service information are associated with each other. The user can acquire information on a building within a predetermined distance range from the user's own terminal position, service information of a store in a specific building, and the like in the field of view.

Patent Document 4 describes a mobile terminal in the information providing service system described in Patent Document 3. When the user presses the positioning button with the mobile terminal pointing to the 9th floor of the building, for example, the mobile terminal measures its own location information (latitude, longitude, altitude, direction, tilt angle, etc.), and the measured position Send information to the server system. In addition, the mobile terminal can obtain a plurality of service information retrieved by the server system.

[0009] In the information providing service system described in Patent Document 5, the service information is linked to the map information of the mobile terminal, the map information and the image data of the service information are displayed on the screen, and the size of the image data is increased. It is designed to display optimally.

The server device for spatial information service described in Patent Document 6 uses an information balloon virtually registered in the real physical space to search and refer to information with an analog operation closer to a human sense on a mobile terminal. In addition, it can provide information to an unspecified number of users with fewer information balloons.

[0010] The guidance information providing device described in Patent Document 7 performs matching between the specified status and the current status, and requests the guidance information providing device when mapping is performed. Thereby, the network load and the load on the guidance information providing apparatus side can be reduced.

The push delivery service providing system described in Patent Document 8 predicts that a mobile terminal has entered a plurality of push delivery areas existing around the mobile terminal itself. As a result, it is possible to reduce the network load that can be used for positioning as much as possible while reducing the number of positioning operations, the load that is applied to the positioning server, and the packet charges required for continuous positioning.

[0011] The route planning apparatus described in Patent Document 9 predicts a route plan or arrival time of a car, and uses a travel record of a car that has actually passed, thereby providing a highly accurate route plan or arrival. Time prediction is possible.

In this way, information providing services are diverse and further progressing.

On the other hand, in recent years, a lot of information transmission and information acquisition (information collection) has been carried out on websites. In particular, bulletin board sites and posting sites on the Internet allow information providers and information acquirers to write information and acquire information in both directions. Recently, the functions of bulletin board sites and posting sites have advanced, and the number of websites called blogs (Blogs: abbreviations for “Weblog”) has increased. The name blog comes from the word “Weblog” t, which combines “Web” and “Log (diary)”.

[0012] This blog is a Web site displaying frequently updated texts such as personal diaries. Many blogs set up links to websites where the owner of the blog has found it on the Internet-youth, topics, and the individual ( (Owner) Contents of their own comments and opinions are displayed in chronological order. A blog has a function that allows other users who visit the website to be linked to from other websites owned by other users by using a simple diary display function. . By using this blog function, individuals can easily open their own websites, which has exploded in popularity and the number of publications on blogs has increased!

[0013] Non-Patent Document 1 describes a technique for adding location information to entries posted using moblog, and sends mail to a mobile phone power mail server using this moblog. You can easily update your blog.

Non-Patent Document 2 describes a service for registering a blog with location information using a GPS mobile phone. In this service, when a user posts with the position information attached to the text of a mobile mail, a link to a map of the location is automatically displayed as an icon on the blog. As a result, it is possible to link an already registered article to a place.

Patent Document 8: Japanese Patent Laid-Open No. 2002-319435

Patent Document 9: Japanese Patent Laid-Open No. 11-272983 The most important thing in the above information providing service is that the user himself / herself, for example, the restaurant menu on the 9th floor of the department store is required in the place where the user stands If there is no service information at the location (entrance) and there is no menu or other service information at that location, the service information can be obtained from the server to which the subscriber is subscribed, and anyone other than the user can obtain the service information. Information can be easily obtained.

[0014] On the other hand, the information providing service provided / provided by an administrator is currently provided with information in a spatial range that can be collected by a person who provides the service (for example, a store owner or an administrator who provides a food service). Only. Therefore, it is rare that the information that the user truly acquires at the place where the user stands is included in the information transmitted by the server system. Therefore, it is possible to provide a large-scale database in the server system and hold various information acquired by the server system in this database.

[0015] However, searching for the desired data among the data held in a large-scale database increases the search time even for a single search, and in addition, a large number of users are in a server system. If a search request message is sent to the server, the processing load on the server system will be excessive and congestion may occur. For this reason, when the processing load becomes excessive, there is a problem that the memory area of the server system is occupied by unprocessed data for a longer time than usual, and multiple lines inside and outside the server system are blocked. More In addition, since call loss occurs due to a blocked line, there is a problem that the operation of the server system may become unstable.

[0016] When the server system pushes information to the mobile terminal, the server system may be provided with a function of calculating the position of the mobile terminal using GPS. There is a problem that the processing load is further increased. Further, there is a problem in the method of accessing information.

Specifically, the location information using the base station of the mobile terminal can be used anywhere because of its wide coverage. On the other hand, since one area is large, information close to where the user stands and information far away are provided to the mobile terminal as well, so another method of indicating the location of the information is required. .

[0017] On the other hand, GPS, IC tag, wireless LAN, etc. can specify a narrow range, but there are few places to install access points for radio wave conditions, so there are limited places or areas that can be used, and users can always The service is not available everywhere.

The present invention was devised in view of such problems, and the service information providing system can easily acquire service information such as a building in a field of view at a place where the user stands, and at that place, Information providing service system that can acquire service information provided at other locations or locations using the same access point, and also enables access restriction and efficient hardware use, and users in the system The purpose is to provide a terminal, a spatial information server in the system, and a service information providing method in the system.

Disclosure of the invention

[0018] Therefore, the information providing service system of the present invention is an information providing service system that provides information to a user terminal, and includes a plurality of three-dimensional space range information corresponding to an actual three-dimensional space, and service information. Information can be cross-referenced between a spatial information server accessing a database holding a plurality of balloon data each associated with a plurality of addresses for obtaining information and a server in the information providing service system described above The location where the first balloon entry has a first balloon entry that represents the entry And the first blog site that obtains each of the balloon data stored in the spatial information server, so the user can provide it at another location different from where the user terminal is located Service information can be acquired. In addition, users can communicate “anytime”, “anywhere”, “anyone”, and can obtain service information “anywhere”. And since blogs are used, information dispatch points can be flexibly set up where needed and useful information can be obtained.

[0019] The spatial information server includes a first balloon entry creating unit that creates a first balloon entry on the first blog site, and a first balloon of the first blog site created by the first balloon entry creating unit. A spatial information server address registration unit that registers the address of the spatial information server in the entry, and a first one that registers the address of the first balloon entry of the first blog site created by the first balloon entry creation unit in the database. It can be configured with a balloon entry address registration unit, and it can be configured to store information on the access authority to the first blog site in the database.

Therefore, in this way, each user can acquire appropriate service information according to the location.

In addition, it is configured to register the address of the spatial information server based on the information on the access authority held in the spatial information server address registration unit database, or as the address for notifying the update of the first balloon entry. It may be configured to register the server address.

[0021] Further, the first blog site may be a blog site owned by the user terminal that transmits the search request. The service information search result and the trackback addressed to the first balloon entry are sent to the user terminal. It is configured to send the address of the second blog site to notify.

The first blog site can be configured so that the functions of the first blog site itself can be added and reduced using plug-ins.

Therefore, in this way, service information in the user's field of view can be acquired, and service information can be acquired based on the user's V, that is, an analog sense.

In addition, the user terminal of the present invention includes a positioning unit that measures position information of the user terminal, a position Information and search range information power multiple balloon definition information power balloon data holding section that holds the balloon data, and update determination section that determines whether or not the balloon data held in the balloon data holding section needs to be updated Based on the determination result of the update determination unit, V is configured to include an update unit that updates the balloon data held in the balloon data holding unit. The service information is automatically collected, and the mobile terminal can acquire the automatically collected service information without moving the location.

[0023] Further, the user terminal has a first blog site owned by the user terminal among a plurality of blog sites having a blog entry capable of cross-referencing information with the server in the information providing service system. It is configured to obtain a summary (information summary) of blog entries created on a second blog site different from the first blog site among the plurality of blog sites.

[0024] The spatial information server of the present invention includes a plurality of balloons in which a plurality of three-dimensional space range information corresponding to an actual three-dimensional space and a plurality of addresses for obtaining service information are associated with each other. Corresponding to the 3D spatial range information around the location information among the multiple 3D spatial range information held by the database based on the data holding database and the location information, search range or balloon name of the user terminal Since it is configured with a search unit that extracts the address and notifies the user terminal of service information corresponding to the extracted address, the user still uses the same access point at that location. Service information provided at other locations or locations can be acquired.

Furthermore, the search unit can be configured as shown in the following (i) -one (iii).

(i) Search the database using the name or part of the name assigned to the balloon data as a search tag, and search for service information to which the name including the name or part of the name is assigned.

(ii) Searching the database using the position information and search range defined in the searched balloon data as search tags, and using the searched balloon data obtained by the search, a position that is geographically close to the searched balloon data Search more balloon data for.

[0026] (ii) The position information and search range in which the searched balloon data is defined are used as search tags. The database is searched, and the balloon data is searched for balloon data again using the searched balloon data, which is geographically close to the searched balloon data.

(iii) Search using the positioning information measured by the position information acquisition means provided in the user terminal as the position information of the user terminal.

Accordingly, in this way, service information such as a building in the field of view can be easily obtained at a place where the user stands.

Furthermore, the database can be configured as shown in the following (iv)-(ix).

(iv) As a plurality of three-dimensional space range information, balloon data having the balloon definition information power including the position information of the user terminal and the search range information is held.

[0028] (V) As a plurality of three-dimensional space range information, the position information including the latitude, longitude, and altitude of the user terminal in the actual three-dimensional space and the search range information represented by the balloon diameter are used as the balloon definition information. Hold as.

(vi) As multiple 3D space range information, position information including the latitude, longitude, and altitude of the target in the actual 3D space and search range information represented by the balloon diameter are held as balloon definition information.

[0029] (vii) Hold at least uniform 'resource' locator or unity resource identifier as a plurality of addresses.

(viii) Hold balloon data acquired by remote communication protocol or email.

(ix) The lifetime is set and retained in the balloon definition information, and the balloon definition data is deleted after the lifetime has elapsed.

[0030] Therefore, since access restriction and efficient hardware use are possible in this way, service information provided in various other locations can be acquired regardless of the location of the user.

Furthermore, the spatial information server may be configured to include a user management unit that restricts access authority to balloon data stored in the database, and further includes a balloon registration unit that registers balloons. The first blog entry may be notified of a registration message including an account of a user different from the registered user who registered the access-restricted balloon data with restricted access authority. in addition, A balloon registered user approval may be sent by e-mail for a user account registration request for access restricted balloon data. Furthermore, one or a plurality of balloon definition information acquired by database search can be configured to be transmitted to the user terminal using a description language based on XML (Extensible Markup Language) format.

Accordingly, in this way, it is possible to perform restriction according to access authority, and for example, it is possible to obtain service information equivalent to that of the subscriber terminal regardless of the subscriber operator of the user terminal. In the service information providing method of the present invention, the first user terminal associates each of a plurality of 3D space range information corresponding to the actual 3D space and a plurality of addresses for obtaining service information. Spatial information server power to register desired balloon data in a database holding multiple balloon data and access the database. 1st user Information on the blog site owned by the terminal with the server in the above information provision service system Create a first balloon entry that represents a blog entry that can cross-reference, and the spatial information server registers the address of the first balloon entry in the database, and the spatial information server registers the spatial information server's address in the first balloon entry. Since the address is registered, the user terminal force accesses the first balloon entry and obtains service information. Service information such as buildings in the field of view can be easily obtained at the place where the user stands, and the service information provided at other places or locations using the same access point at that place. You can get it.

(A) Description of an embodiment of the present invention

The main information providing service of the information providing service system (hereinafter simply referred to as “system”) to which the present invention is applied is primarily mobile users, mobile phones, PDA (Personal Digital Assistants) and other movable users. For example, it is a service that provides information (service information) such as a menu of a restaurant of a department store near the place where the user stands to the terminal. In addition, the second service uses a mobile terminal to store information on department stores, such as the names and reputations of stores occupying each department store floor, product information, etc. It provides the use of writing information (information on location) by. This second service automatically collects a lot of “location information” by a blog, which will be described later, so that users can obtain useful information from the blog.

[0035] In addition to these two types of services, the system has a function of providing service information to the mobile terminal using the push Z pull function. In addition to providing service information directly to mobile terminals, the system also provides services using mobile terminals, such as displaying service information on information terminals connected to mobile terminals by users. Yes In addition to the above two types, examples of “service types” that this system provides to users include the use of blogs, advertisements using push Z-pull, telephone calls, Internet connection, mail transmission / reception, and -use. Distribution etc. In addition, examples of “service information” include: (i) company advertisements, product information for stores and department stores, public information on public institutions and transportation, (ii) map display or geographical guidance, and (iii) still images, for example. It means content distribution etc.

FIG. 1 is a configuration diagram of a system to which the present invention is applied. The system 100 shown in FIG. 1 is an information providing service system that provides information to the mobile terminal 2, and the user power terminal position (position in a three-dimensional space consisting of latitude, longitude, etc. for the mobile terminal) “Location information” collected by blog entries linked to the spatial information server after acquiring service information such as restaurant menus from the spatial information server. Is to get. [0037] This blog is a Web site (Web site consisting of a top page and a plurality of Web pages) in which frequently updated text such as a personal diary is displayed on the top page. By setting up this blog on the Internet, a lot of information about the location is automatically collected, and users can obtain useful information from the blog. Automatic information collection is realized by linking to a Web site where users using blogs send news, topics or information. The difference between this blog and a website such as a diary or -youth is that each blog has a link function with other blogs. This linkage function is realized by, for example, RSS (Fig. 6) and trackback (Fig. 8) described later.

[0038] A blog entry is a Web site having a URL. For example, for a specific shopping street, "Store A is selling cheaply", "Restaurant B's recommended menu is tarakopasta. This is a Web site that automatically collects content related to places (shopping streets) such as “sale and recommended menus”. A blog entry is similar to a regular bulletin board site in that the content gathers automatically. In contrast, a blog entry differs from a bulletin board site in that two or more blog entries can refer to each other's content. In the bulletin board site, content is automatically gathered by many users writing their opinions and impressions on the bulletin board, so individuals send messages to the website. On the other hand, in blog entries, websites are linked to each other so that information can be referred to each other, and websites send messages to other websites. Details of these blogs and blog entries will be described later.

A system 100 shown in FIG. 1 includes a mobile terminal (user terminal of the present invention) 2, a mobile terminal (other user terminal) 5, a base station 50, a wireless telephone network 51, and a gateway server 5 2. And the Internet 53, server system (where the spatial information server of the present invention is provided) 54, blog sites 3, 4, 36, spatial information server 6, and four GPS satellites 90. ing.

Here, the base station 50 performs wireless communication with the mobile terminals 2 and 5. The wireless telephone network 51 is a subscriber telephone line. In this system 100, the mobile terminal 2 and the spatial information server 1, the blog site 3, and the blog site 4, 36, etc. have wireless specifications, but in the following description, unless otherwise specified, the wireless signal Send / receive and change A detailed description of the process such as demodulation is omitted.

[0041] Next, the Internet 53 is a network to which many Web servers are connected, and the gateway server 52 filters signal data.

In addition, the server system 54 provides a server for the operator of the system 100, transmits service information to the mobile terminals 2, 5 etc. via the Internet 53, and “location information” from the blog site 4 etc. The data is collected and transmitted to the mobile terminals 2 and 5. In addition, the server system 54 includes a spatial information server 1 having a balloon database 7 described below that holds data relating to spatial information.

[0042] The blog site 3 is a Web site opened by the owner of the mobile terminal 2 and has a blog function. Blog site 4, 36 having a balloon database 7 that created the blog site 3 independently a _We b site operators and different other operators of the system 100 is opened. The blog site 3 sends and receives messages to and from the mobile terminal 2 and the server system 54, and notifies the blog sites 4 and 36 of information mutually by track knock or the like. The spatial information server 6 is provided by another business operator and is connected to the Internet 53.

[0043] Further, each of the four GPS satellites 90 transmits a radio wave including an identification ID (iDentification) of each satellite and a transmission time of a signal including the identification ID. Each GPS satellite 90 is arranged so that the mobile terminal 2 can capture radio waves from the GPS satellite 90 at any location.

In the following, balloon data (bubble data) that holds a 3D spatial position and service information associated with the 3D spatial position will be described, followed by a spatial information server 1 that holds the balloon data, and a spatial information server. Each of the mobile terminal 2 that transmits the terminal location to 1 and the blog that links to the spatial information server 1 and automatically collects information about the location will be described in detail.

The spatial information server 1 provided in the server system 54 has a balloon database 7 that holds balloon data. Between the balloon database 7 and a blog entry (described later) provided in the blog site 3. This is a server that is linked so that the mobile terminal 2 can access the blog site 3. This balloon data and balloon definition information will be described in more detail with reference to Figs.

[0045] A balloon (bubble) is data held in the balloon database 7, and the space occupation information is in a specific space in the three-dimensional space, which is like a bubble floating in the three-dimensional space. Fig. 2 is a diagram schematically showing the building layout in the space. The four types of buildings shown in Fig. 2 all have the same longitude and different latitudes. For example, building A is located in the range of latitude A-1 to A + 1, and the center positions of building B, C stadium, and D tower are latitude B, C, and D, respectively. These latitude and longitude units are both. (Degrees), '(minutes), "(seconds).

[0046] The business operator of the system 100 creates a database as shown in Fig. 3 below, using the building layout in the real space shown in Fig. 2 as balloon data, and builds a virtual space on the balloon database. is doing.

FIG. 3 is a diagram showing an image of a three-dimensional space range of balloon data according to an embodiment of the present invention (information balloon: hereinafter simply referred to as a balloon), and the information balloon shown in FIG. 1-117 represents the image corresponding to the AD building (Figure 2). In other words, each of the information balloons 11-17 is a visual representation of the virtual space constructed in the balloon database. Each of these information balloons 11-17 associates 3D spatial range information consisting of the latitude, longitude, altitude and balloon diameter of an object with information such as products or services provided in each building. ing.

[0047] Information balloons 1, 5, 8, and 9 represent A building, B building, C stadium, and D tower, respectively. The information balloon 1 has information balloons 2, 3, and 4 therein. These information balloons 2, 3, and 4 represent images corresponding to the floors of each floor of building A.

Then, in order to obtain service information (for example, a restaurant menu) held in association with these information balloons, the user operates an operation unit (for example, “position information positioning button” provided on the portable terminal 2 at a place where the user stands. ) Etc.) and GPS satellite 90 ( Figure 1) is used to measure the terminal position. Then, the portable terminal 2 transmits the measured terminal position to the server system 54. On the other hand, when the server system 54 receives the terminal position, the server system 54 searches the balloon data shown in FIG. 4 below, and virtual position information (position information in the virtual space) corresponding to the received real position information (position information in the real space). Get location information.

FIG. 4 is a diagram for explaining balloon data according to an embodiment of the present invention. Balloon numbers 1 to 17 shown in FIG. 4 correspond to balloon numbers 1 to 17 shown in FIG. ing. The data represented by AZXZ0Z3 represents the latitude Z longitude Z altitude Z balloon diameter. For example, balloon number 2 corresponds to the 3rd floor of building A shown in Fig. 3, and server system 54 uses this data as latitude A (unit: frequency), longitude X (unit: frequency), altitude 3 (Corresponding to 45m) and balloon diameter 1 converted and held. Altitude 0 indicates that the building is in contact with the ground. Altitudes 1, 2, and 3 indicate values corresponding to true values (for example, 15m, 30m, and 45m). 5-4 are values corresponding to true values (for example, lm-8m). In addition, each balloon is held associated with a URL.

[0049] Then, the server system 54 searches the balloon database using the actual position information (position information in the three-dimensional real space) from the mobile terminal 2 as a search tag, and acquires virtual position information. The URL stored in association with the virtual location information is transmitted to the mobile terminal 2.

As a result, based on the balloon database that holds the spatial information, the user can intuition in real space such as “What kind of store is on the 9th floor of that building” and “What is the lunch menu of the restaurant”. The desired service information can be acquired with a sense or analog.

[0050] In addition, the shape of the balloon may be any shape such as a sphere, an elliptic sphere, or a quadrangular prism (rectangular cuboid) conforming to the volume of the building. , Longitude, altitude) and radius (balloon diameter) can be used to identify the balloon and save the storage area of the balloon database 7. Note that the balloon can be set not only as a closed space (occupied space) but also as a part of a predetermined range in the space, It can also be set to an infinite range on one side.

Next, each of mobile terminal 2, server system 54, and blog site 3 shown in FIG. 1 will be described in more detail with reference to FIG.

First, the mobile terminal 2 will be described.

FIG. 5 is a block diagram of the mobile terminal 2 according to an embodiment of the present invention. The mobile terminal 2 shown in FIG. 5 includes (i) a positioning function of the terminal position, and (ii) a three-dimensional real space area centered on the terminal position measured by the user (a radius when the balloon shape is spherical). It has a function to define as an information balloon and send the area data to the spatial information server 1 and (iii) a function to obtain a summary (information summary) of another blog entry 9 from the blog site 3. .

[0052] Here, the summary acquisition method is such that the balloon search unit 24 (described later) of the spatial information server 1 uses the search request message specifying the terminal position and the search range from the mobile terminal 2 as the periphery of the mobile terminal 2. Blog entry 3 for blog site 3 linked to this searched balloon and other blog entry 9 linked to track entry 8 by trackback from blog site 3. RSS (Really Simple Syndication or RDF Site Summary) data format. Here, RSS is metadata that describes a summary (summary of site content) used in blog sites and -use sites.

[0053] The configuration of the mobile terminal 2 will be further described in detail.

The mobile terminal 2 shown in FIG. 5 includes an RF (Radio Frequency) module 40, a display unit 42, a GPS receiver 11, a GPS control unit 12, a geographic function calculation unit 13, and NVML (Navigation Markup Language) data. The access unit 14, the balloon event management unit 15, the holding unit 15 a, the balloon search unit 16, the balloon registration unit 26, the RSS reader 18, and the operation unit 41 are configured.

Here, the RF module 40 is a radio circuit that modulates and demodulates a radio signal and wirelessly transmits and receives to and from the base station 50. When a mobile phone as the mobile terminal 2 is used, a microphone, a speaker, an audio processing circuit, and An amplifier circuit or the like (not shown) is provided to enable voice communication. A mobile device 2 such as a PDA, which is different from a mobile phone, is connected to the RF module 40 and various other devices. A format conversion circuit (not shown) for wireless transmission / reception signals that conforms to the standard can be provided, so that users can use the information services detailed above and below, regardless of the specifications of the wireless section. it can.

[0055] In addition to displaying the received service information and location information, the display unit 42 displays various setting items and operation items for the user in a web browser (web browser, browser program, browser application software). For example, it is realized by a display, a display driver, or the like. The notification function for the user can also be realized by providing a ringer (not shown) that outputs sound and sound and a vibrator that generates vibration in addition to the display unit 42.

[0056] The GPS receiver 11 functions as a positioning unit that measures the position information of the mobile terminal 2, and more than 4 out of 25 GPS satellites 90 (24 units and 1 spare unit). It is a device that receives radio waves from GPS satellite 90 and measures the terminal position. An example of the positioning method is that the GPS receiver 11 demodulates the radio wave and the GPS satellite 90 identification ID, the transmission time written by the GPS satellite 90 included in the radio wave, the reception time by the GPS receiver 11 The distance from one GPS satellite 90 is obtained based on the time difference between and. In addition, information is obtained in the same manner for the other three GPS satellites 90, and the distance to the GPS satellite 90 is calculated to obtain the latitude, longitude, and altitude of the mobile terminal 2 itself.

[0057] This GPS receiver 11 uses a data format called NMEA (National Marine Electronics Associates) format via a serial communication port 200 provided in the mobile terminal 2, and each module inside the mobile terminal 2 Communicate with. For example, when the main body side of the mobile terminal 2 acquires latitude and longitude information from the GPS receiver 11, data called GGA (Global Positioning System Fixed Data) is used. An example of GGA is shown in the next line.

[0058] $ GPGGA, 161229.487,3723.2425, N, 12185.3416, W, 1,07,1,0,9,0, M, „, 0000 * 18 Next, the GPS control unit 12 determines the positioning of the GPS receiver 11. It controls the positioning such as start and stop positioning, and acquires the terminal position measured by the GPS receiver 11. The GPS receiver 11 and the GPS control unit 12 work together to detect the position. Functions as information acquisition means (11, 12), and the balloon search unit 24 of the spatial information server 1 As the position information of the terminal 2, the position information obtained by the position information acquisition means (11, 12) provided in the mobile terminal 2 is used for searching.

[0059] In addition to these functions, the GPS control unit 12 has a function of notifying a communication command to the GPS receiver 11 from each of the balloon event management unit 15, the balloon search unit 16, and the balloon registration unit 17. The function is realized by an external function. Here, each of the communication command and the external function will be described in further detail.

The communication commands of the GPS control unit 12 mainly include the types of GGA data reception (data acquisition) from the GPS receiver 11, communication start for opening the serial communication port 200, and communication end for closing the serial communication port 200. Yes, it is a command inherent in the periphery of the serial communication port 200. The external function is a means for realizing this communication command. As the external function function, for example, a method in which the balloon registration unit 17 executes or starts an external function using software, or a method of driving a hardware terminal such as LSI (Large Scale Integration) can be used.

Thereby, the balloon registration unit 17, the balloon search unit 16, and the balloon event management unit 15 use the external function of the GPS control unit 12 to start communication, acquire data, and end communication. Processing functions to use 11 are realized.

Communication start and communication end are performed only at the beginning and end of the entire process, and what the balloon registration unit 17, balloon search unit 16, and balloon event management unit 15 need is It ’s just data acquisition.

[0061] Each function of the balloon registration unit 17, the balloon search unit 16, the non-lane event management unit 15, the GPS control unit 12, and the like is performed by, for example, hardware such as LSI, CPU (Central Processing Unit), ROM (Read Realized by software that collaborates with only memory (RAM) and random access memory (RAM).

The operation unit 41 shown in FIG. 5 is a kind of user interface for allowing the mobile terminal 2 to execute commands such as position information positioning, rain registration, and balloon search. How to place buttons and keys such as “Positioning button”, “Balloon registration button”, etc. by the user, or by scrolling the page displayed on the display unit 42 by the user, “Positioning information positioning”, “Balloon registration” , "Balloon search" and other commands For example, a method of selecting and executing a command such as “position information positioning” can be used on the page on which the command is displayed. Note that the method of realizing the operation unit 41 is an example, and the present invention is not limited to these.

[0062] Next, the geographic function calculation unit 13 converts the geodetic system output from the GPS receiver 11 (coordinate system representing a spatial position such as longitude and latitude) into a geodetic system used by software such as the server system 54. To do. This allows the system 100 to process data with the same geodetic system even if the geodetic system has multiple methods.

Also, the NVML data access unit 14 converts the description language (balloon data elements such as the center position, range, balloon name, etc.) described using the NVML 34 from the spatial information server 1 and outputs the converted language. Is. The spatial information server 1 uses the NVML 34 based on the XML format, which is the de facto standard as a data description language in the Internet 53, to acquire one or more balloon definition information obtained by searching the balloon database 7 to Send to. For this reason, the NVML data access unit 14 processes a unique vocabulary (grammar) used only by the NVML 34 in accordance with the NVML 34 data structure.

[0063] NVML34 is based on XML that defines areas (point information or location information) and routes in a three-dimensional space, and can describe additional information such as lunch menus for each location and route. It is also possible to describe the route to the location as a series of location information and additional information (for example, described using text, sound, images, etc.).

Thereby, between the portable terminal 2 and the spatial information server 1, it is acquired in the balloon definition information 1S NVML format. In addition, by using NVML34, it is easy to apply to various terminal software in that it can be confirmed by human eyes, it is easy to read, is flexible to change, and filtering is easy.

Note that the spatial information server 1 can also search only for balloons owned by a specific user. In this case, when the mobile terminal 2 transmits a balloon search request message to the spatial information server 1, the mobile terminal 2 writes the user account previously given at the time of balloon registration in the balloon search request message. Then, the balloon search unit 24 provided in the spatial information server 1 uses the balloon database 7 for the SQL (relational database The user account specified by the mobile device 2 is specified as a search condition when searching using a standardized language for data definition and operation language. Items can be filtered and searched.

Subsequently, when the balloon event management unit 15 of the mobile terminal 2 acquires, from the spatial information server 1, the balun data around the mobile terminal 2 in the virtual space corresponding to the real 3D space position of the mobile terminal 2 is acquired. This is for specifying a wide search range, acquiring a lot of balloon data, and holding it in the holding unit 15a. Here, the holding unit 15a is a memory that holds balloon data having a plurality of balloon definition information forces including position information and a search range information force.

[0066] The rain event management unit 15 periodically acquires the GPS receiver 11 power terminal position using the GPS control unit 12, searches the memory (holding unit 15a), and stores the terminal position in the balloon. Monitor entry and exit (entering and exiting). This monitoring is always performed in the knock ground, and when entry / exit is detected in the no-lane, the RSS reader 18 automatically obtains a summary from the blog site 3 and prompts the user using message display, voice, etc. Display a summary. At this time, the user seems to be distributed by push.

[0067] Further, when the terminal position also includes the range of the balloon data held in the holding unit 15a, the mobile terminal 2 automatically searches the spatial information server 1 using the balloon search unit 16, and You can also update the data. When a balloon search is performed on the spatial information server 1 in the past, the holding unit 15a holds balloon data around the terminal position acquired at the past time point. When the geographical range of the balloon data does not include the current terminal position, it is detected as an inconsistency and balloon data is newly acquired. Therefore, the mobile terminal 2 uses the balloon data held in the holding unit 15a to determine whether update is necessary, based on the update determination unit (not shown) and the determination result of the update determination unit. And an update unit (not shown) for updating the balloon data held in. As a result, data update and data management of the holding unit 15a are performed.

[0068] Next, the balloon search unit 16 asks the balloon search unit 24 in the spatial information server 1 to obtain the balloon data together with the function V, the terminal position and the search range as parameters. And a search function using a balloon name. The balloon registration unit 17 has a function of registering balloon definition information set by the user (balloon data elements such as center position, range, balloon name, etc.) in the balloon database 7 of the spatial information server 1 and a blog site 3 A function for generating entry 8. The terminal position obtained using the GPS control unit 12 can be used as the center position of the balloon.

[0069] Next, the RSS reader 18 retrieves RSS data from the blog site 3 and displays a summary of the blog entry 8 and other blog entries 9 and 37 linked by the trackback to the user. If this information is selected, the texts of the blog entries 8, 9, and 37 are displayed on the display unit 42. Then, when the balloon search unit 16 and the balloon event management unit 15 of the mobile terminal 2 detect the rain and acquire the balloon data from the spatial information server 1, the RSS reader is used with the URL of the blog entry 8 described therein as a parameter. 18 is launched, and RSS summary is obtained from blog site 3 using the URL. As a result, the user can acquire site information used on the blog site or the -use site.

[0070] Furthermore, the mobile terminal 2 is a blog site owned by the mobile terminal 2 itself among the blog sites 3, 4, and 36 that have blog entries that allow information to be mutually referred to various servers in the system 100. 3 is used to obtain a summary of the blog entries created on blog site 3 (the second blog site) 4 that is different from blog site 3 of blog sites 3, 4, and 36. That is, the mobile terminal 2 acquires a summary of the other blog entry 9 via the blog site 3 (or via the blog site 3).

[0071] In addition, the portable terminal (another terminal) 5 shown in FIG. 5 is a terminal not provided with a position information positioning function. Similar to the portable terminal 2, the portable terminal 5 has balloon registration and balloon search functions. On the other hand, when registering a balloon, the user manually inputs or sets known position information in the portable terminal 5, and the registered balloon data is given a balloon name by the spatial information sensor 1 or the user. .

[0072] Furthermore, each of the mobile terminals 2 and 5 has installed dedicated software (program application) for using the push Z pull service.

This ensures that the pull or push method is effective when the user is in a particular location. Position information is transmitted to the server system 54. In the case of pulling, the server system 54 searches (pulls) the service information corresponding to the received location information from the balloon database 7 provided in the server system 54 itself, and sends the service information obtained by the search to the mobile terminal 2. To send. On the other hand, in the case of push, the system 100 detects that the mobile device 2 has entered a specific location, and searches the balloon database 7 for the location of the service information related to the location where the user stands, and automatically retrieves the retrieved service information. The information is transmitted to the mobile terminal 2, and the user is notified (pushed) of the service information by looking at the display unit 42 of the mobile terminal 2.

[0073] Therefore, for example, when a user contacts a balloon registered in advance in one of a number of stores facing the street as data in the balloon database 7, the mobile terminal 2 is called by the push, and the user Get information such as restaurant menus and opening hours information.

Further, in order to provide service information following the movement of the mobile terminal 2, the mobile terminal 2 always transmits the acquired spatial position to the system 100 side. Then, the geographic function calculation unit 13 performs format conversion on the position information data obtained from the GPS satellite 90 and transmits the converted position information data to the server system 54.

Accordingly, the user can request the server system 54 to provide service information at all times or at a desired timing.

Next, the server system 54 shown in FIG. 1 will be described with reference to FIG. The server system 54 shown in FIG. 5 is an object in a three-dimensional space (for example, a building, each floor of a building, an object that actually exists such as a signboard, or an object that moves in a space) or the latitude, longitude, altitude of a desired space, and will be described later. Multiple 3D real space range information occupancy information (spatial range information or space region information) consisting of balloon diameters (bubble diameters) and addresses associated with each object (URL [Uniform Resource Locator: Uniform Resource Locator] ])) And a server that holds a plurality of balloon data associated with each other. Here, the URL functions as an identifier for identifying each three-dimensional real space range information or an address for obtaining service information. In addition, the server system 54 includes space occupancy information of the desired space, various information to be associated with the desired space, or URLs associated with the various information. It can also include lane data associated with.

[0075] Note that the server system 54 may be a distributed type in which a plurality of functions such as e-mail transmission / reception functions, domain name retention, search, and assignment are assigned to separate servers, or a plurality of functions may be combined into one unit. It can be configured in a centralized manner concentrated on Sano.

Next, the spatial information server 1 has a balloon that holds a plurality of balloon data in which a plurality of three-dimensional space range information corresponding to the actual three-dimensional space and a plurality of addresses for obtaining service information are associated with each other. It accesses the database 7 and is connected to each of the mobile terminals 2 and 5, the blog site 3, and the other spatial information server 6. This spatial information server 1 includes an input / output unit 26a, a balloon registration unit 26, a rain search unit 24, a user registration unit 20, a mail address management unit (mail GW [Gate Way]) 20a, and a search extension. Processing unit (extended search function) 22, format conversion unit 19, entry update detection unit 25, balloon status management unit 23, user management unit 21, balloon database (database, spatial information database: DB [Database ]) It is composed of 7 and

[0076] Here, the input / output unit 26a formats the input data and extracts the message type and user name included in the data, and also outputs the message type, user name, and address to the data output to the Internet 53 side. Etc., and the written data is formatted and sent to the Internet 53 side.

The lane registration unit 26 receives the balloon definition information from the balloon registration unit 17 of the mobile terminal 2 and registers it in the balloon database 7, and notifies the blog site 3 of the posting API and blog entry in the blog site 3. The first balloon entry creation section that creates blog entry 8 on blog site 3 and the first balloon entry of the first blog site created by the first balloon entry creation section The spatial information server address registration unit that registers the address of information server 1 and the first database entry that registers the address of the first balloon entry of the first blog site created by the first balloon entry creation unit in the balloon database 7 A balloon entry address registration unit is provided.

[0077] Then, the balloon registration unit 26 sends a posting API (registration message) including a user account different from the registered user who registered the access-restricted balloon data with limited access authority to the blog entry 3 of the blog site 3. To the blog Set the category of entry 8, set the contents of the posting API automatically (automatic classification), and set the entry notification destination server. This makes it possible to obtain all the information of access-restricted none data using the API and to refer to access-restricted balloon entries.

Here, the posting API is a message for the blog site 3 transmitted from the spatial information server 1 and is an API for posting a blog entry. For example, specifications such as metaWeblogAPI are used. The API for creating a new entry is called metaWeblog.newPost in metaWeblogAPI. The parameters of this metaWeblog.newPost are, for example, ID of blog site 3, user name of blog site 3, password of blog site 3, Includes the registration details and information specifying whether or not to release the registered blog entry 8. When the mobile terminal 2 succeeds in balloon registration, the ID of the blog entry 8 among the parameters of this API is returned to the mobile terminal 2.

[0079] Further, the balloon search unit 24 is based on the position information of the mobile terminal 2, the search range, or the balloon name, and the three-dimensional surroundings of the position information among the many three-dimensional spatial range information held by the balloon database 7. A URL corresponding to the spatial range information is extracted, and service information corresponding to the extracted URL is notified to the mobile terminal 2 and functions as a search unit. When inquired from the balloon search unit 16 of the mobile terminal 2, the balloon search unit 24 searches the balloon database 7 and transmits the search result to the mobile terminal 2. An example of balloon data arrangement in the balloon database 7 is a rectangular parallelepiped or spherical shape that extends from the entrance of the store registered in the balloon to the center of the street where the pedestrian walks. Then, the contact with the system 100 is detected by the system 100 and information is transmitted to the pedestrian.

[0080] Further, the search expansion processing unit 22 is activated by the balloon search unit 24, searches the spatial information Sano 1 using the balloon name as a search tag, and based on the balloon definition information of the balloon hit by the search, The center position of the hit balloon is obtained, and the none database 7 is searched again using the obtained center position. Here, the search method of the balloon search unit 24 will be described in detail. The balloon search unit 24 (i) uses the name or part of the name given to the balloon data as a search tag. It is also possible to search the balloon database 7 and search for service information given a name including a name or a part of the name, and (ii) position information and search defined in the searched balloon data. The balloon database 7 can be searched using the range as a search tag, and the searched balloon data obtained by this search can be used to further search the searched balloon data and geographical data of a location close to the searched balloon data. .

[0081] Thereby, the user of the terminal 5 that does not have the position information positioning function first transmits a name related to the location where the user is located to the spatial information server 1, and the spatial information server 1 is stored in the balloon database 7. All the balloon data is searched for using the name of the data and transmitted to terminal 5, and the user selects one of the received balloon data! To search for. In other words, the user of the terminal 5 uses the position information of the balloon data searched by the name to perform a secondary search for balloons around that position. In addition to these, the balloon search unit 24 performs (iii) search using the positioning information obtained by the position information acquisition means provided in the mobile terminal 2 as the position information of the mobile terminal 2, or (iv) the mobile terminal 2 Receives an inquiry from balloon search unit 16 of terminal 2, searches balloon database 7 and returns the result, and uses format conversion unit 19 to convert the output result from train database 7 to NV ML format. You can also As a result, the calculation load of the mobile terminal 2 can be reduced, and the convenience of search is improved.

[0082] Then, when the mobile terminal 2 is restricted in access to the detected balloon, or when the inquiring user does not have authority, the URL of the blog entry 8 is not output, and instead the user registration unit 20 The URL is output.

The e-mail address management unit 20a holds e-mail addresses of registered users who can use the balloon registration and balloon search information services, and performs execution processing for balloon registration and balloon search for registered users. It also has a mail address management function. Specifically, the e-mail address management unit 20a grants an account for providing information services for both balloon registration and balloon search (or either! /, Or either) to registered users. Each time, an e-mail address is generated and the generated e-mail address is stored in a memory (not shown). [0083] Thus, when the email address management unit 20a receives each request message for the noon registration and balloon search included in the email from the mobile terminal 2, the user of the mobile terminal 2 determines whether or not the user is a registered user. If the user is a registered user, the balloon is registered based on the balloon diameter (size), balloon installation position, etc. included in the request message. When the received request message includes a none search request, the balloon database 7 is searched based on the location information of the mobile terminal 2 included in the request message. Therefore, the mail address management unit 20a also has a gateway function for filtering received mail.

[0084] Further, the format conversion unit 19 sets the output data format of the search result to the NVML format when the balloon search unit 24 of the spatial information server 1 transmits the search result of the balloon database 7 to the mobile terminal 2. And so on.

Then, the user management unit 21 restricts access authority to the balloon data held in the balloon database 7, and for example, the ID of the blog site 3 and the blog site 3 are assigned to the lane registration unit 26 described below. The user information regarding the authority to create the blog entry 8 such as the user name and password of the blog site 3 is notified. Then, the balloon registration unit 26 can acquire user information from the user management unit 21 and generate a blog entry 8 in the blog site 3.

Here, the present system 100 assumes that the registered user of the balloon owns the blog site 3 for creating the blog entry 8. Therefore, the registered user who accessed the spatial information server 1 can freely generate the blog entry 8 without managing the user information. Information is managed. Then, an account that gives access to the registered balloon data is given to the user who registered the balloon data, thereby making it impossible to detect in searches from other than the registered user.

[0086] Further, the user management unit 21 issues an account to the mobile terminal 2 that uses a balloon, and restricts access authority to the balloon. This restriction may be set at a plurality of levels such as completely prohibiting access, partial access to balloon data, and access to all balloon data. In addition, the user management department 21 Can also send a balloon registered user's approval by email for user account registration requests for restricted access balloon data.

[0087] Next, the balloon state management unit 23 manages the lifetime of the balloon, and more specifically, whether or not the lifetime of the balloon is specified by the user at the time of registration. Determine whether. The balloon state management unit 23 deletes the balloon definition information from the balloon database 7 when the lifetime expires. With this balloon deletion function, the balloon state management unit 23 can set the expiration date of the lifetime instead of making the fee for registering the no-lane free. The balloon state management unit 23 can provide the information service so as to charge the user when the balloon is to be continued after the expiration date.

[0088] Next, the entry update detection unit 25 monitors whether the blog entry 8 linked to the balloon database 7 by the link 31 is updated by track back or the like. The URL of the entry update detection unit 25 is set as the URL of the entry update notification destination server when the rain registration unit 26 of the spatial information server 1 creates the blog entry 8 on the blog site 3 using the posting API. Is done.

[0089] In addition, the user registration unit 20 is provided separately from the balloon database 7 or the balloon database 7 with respect to access authority to the blog site 3 such as a user account (user name, user ID) and password. It is held in a storage device (not shown). When registering a balloon, the user must register an account. On the other hand, when searching for balloons, users need to register when searching for balloons with limited access that do not require account registration. As a result of this user registration, the user is registered in the spatial information server 1 as a balloon user, and can make a request to the user registration unit 20 for a search using the access-restricted lane.

[0090] Then, the URL of the user registration unit 20 is included in the balloon data returned to the mobile terminal 2 by the spatial information server 1 when a no-restricted access is searched. When the user selects the URL of the user registration unit 20 set in the balloon data, the user registration unit 20 is activated and the user's own account can be registered in the balloon. After registering an account with a restricted access balloon, when the user searches for the balloon, The URL of the blog entry linked to the balloon will be returned.

Accordingly, the spatial information server address registration unit of the balloon registration unit 26 registers the URL of the spatial information server 1 based on the user account, password, etc. stored in the balloon database 7, and The URL of spatial information server 1 is registered as the URL to notify the update of entry 8! /.

Next, the balloon database 7 is a database provided in the spatial information server 1 and holds balloon data having balloon definition information linked to the blog entry 9 as an element. The items of the lane definition information include the center coordinates, range (balloon diameter, etc.), lane name, category, lifetime, URL of the linked blog entry 9 and other spatial information servers where balloons at the same location exist. URL (Uniform · Resource · Locator) or URI (Uniform · Resource · Identifier) of 6 balloon search parts (not shown). The balloon database 7 accessed by the spatial information server 1 is provided as an integral part of the spatial information server 1 itself, provided separately from the spatial information server 1 in the server system 54, or any of the Internet 53 You can set it up somewhere!

Further, the balloon definition information will be described in detail.

The balloon database 7 holds (i) balloon data composed of balloon definition information including position information of the user terminal and search range information as a plurality of three-dimensional space range information, or (ii) a plurality of three-dimensional space range information. For example, the location information consisting of the latitude, longitude, and altitude of the user terminal in the actual 3D space and the search range information represented by the balloon diameter are stored as balloon definition information. (Iii) Multiple 3D space ranges As information, the position information consisting of the latitude, longitude, and altitude of the target in the actual 3D space and the search range information represented by the balloon diameter can be stored as balloon definition information.

[0093] The balloon definition data is described in the NVML language based on the XML language that describes the area and route in the three-dimensional space, and for each described position and route, a lunch menu or the like is provided. Additional information is described. As a result, the user can acquire information in various formats.

In addition, the balloon database 7 sets and maintains the lifetime in the balloon definition information. After the lifetime, the balloon definition data is deleted, so that the user can always obtain new information.

[0094] Regarding the registration of the balloon definition information, the balloon database 7 holds balloon data acquired by a remote communication protocol or mail. Specifically, the balloon definition information is sent to the spatial information server 1 by both HTTP (GET and POST) commands, or sent to the spatial information server 1 by mail and registered in the balloon database 7, The registration result can be returned to the sending user by e-mail. Thereby, balloon definition information can be registered quickly, and the registration result can be confirmed. In addition, each individual can register balloon definition information, improving the convenience of registration operations.

Next, the blog site 3 shown in FIG. 5 has a blog entry 8, and this blog entry 8 is linked to the blog entry 9. The blog entry 9 can refer to “location information” in the space area of the balloon data stored in the balloon database 7. The blog site 3 is a blog site owned by the user of the mobile terminal 2 that transmits the search request.

Therefore, the present system 100 holds a plurality of pieces of balloon data in which a plurality of pieces of 3D space range information corresponding to an actual 3D space and a plurality of addresses for obtaining service information are associated with each other. Location where the blog entry 8 has a blog entry (first balloon entry) 8 representing a blog entry that can cross-reference information between the spatial information server 1 accessing the balloon database 7 and the server in the system 100 And a blog site (first blog site) 3 that respectively obtains information on the information and balloon data stored in the spatial information server 1.

[0097] In addition, in the service information providing method, first, the mobile terminal 2 has a plurality of three-dimensional space range information corresponding to an actual three-dimensional space and a plurality of URLs for obtaining service information. Desired balloon data is registered in the balloon database 7 that holds a plurality of assigned balloon data.

The spatial information server 1 accessing the balloon database 7 can cross-reference information with the server in the system 100 to the blog site 3 owned by the mobile terminal 2. Create blog entry 8 that represents a valid blog entry.

The spatial information server 1 registers the URL of the blog entry 8 in the balloon database 7 and registers the URL of the spatial information server 1 in the blog entry 8.

Then, the mobile terminal 2 accesses the blog entry 8 and acquires service information. The other blog site 36 is operated by an operator different from the operator of the spatial information server 1 and has a blog entry 37 linked to the blog entry 8 of the blog site 3. When a link is generated between blog entry 37 and blog entry 8 by trackback, link entry 33 detects whether blog entry 8 and blog entry 37 are linked by link entry 33 in both spatial information server 1 and spatial information server 6. Each update is detected. The spatial information server 1 refers to the blog entry 37 to acquire the URL of the balloon search unit (not shown) of the spatial information server 6 and register it in the balloon database 7.

On the other hand, the spatial information server 6 acquires the URL of the balloon search unit 24 of the spatial information server 1 by referring to the blog entry 8 and registers it in the balloon database 10. When the grind terminal 2 uses the spatial information server 1 to search for balloons, the spatial information server 1 returns the balloon information obtained from the balloon database 7 to the mobile terminal 2, and in the balloon database 7, the same as the detection balloon. The URL of the balloon search unit 24 of another spatial information server 6 having a balloon at the place can be returned.

[0100] Then, after the mobile terminal 2 searches for balloons using the spatial information server 1, it can continue to search for rain using the spatial information server 6.

As a result, the system 100 (i) balloon definition information is stored in the balloon data base.

This function is used to detect balloons around the location where the mobile terminal 2 is located using this balloon data and location information. (Ii) An information copy associated with a location such as a shopping street A blog entry 8 is created as a Web site for the mobile terminal 2 to access the contents, and a function for allowing a large number of mobile terminals 2 to browse information contents automatically collected in the blog entry 8 is added.

[0101] For this reason, blog entries 8 and 9 also represent websites created using a CMS (Contents Management System) called a blog. Also, Log entries 8 and 9 are Web sites created using Web technology. Therefore, using track knock makes it easy for users other than registered balloon users to link their own blog entries 9 to blog entries 8 of registered balloon users.

[0102] In addition, since information content related to a location is automatically collected in a balloon created by a balloon registered user, users other than the balloon registered user can use a large number of information content related to the location.

In addition, the data of blog entries 8 and 9 are stored in the banolane database of blog sites 3 and 4, and the name of the user who sent the trackback is registered in the balloon database. At the same time as the blog entries ₈ and 9 are created, the mobile terminal 2 provides HTML (Hyper Text Markup Language) for accessing the blog entries 8 and 9 and a summary of the blog entries 8 and 9 RSS A summary is output.

[0103] Thus, the blog entries 8 and 9 also function as a kind of Web page. The entity of blog entries 8 and 9 is balloon database 7 etc. HTML for user interface, RSS file providing summary of registration information to user, XML—RPC (Remote procedure call in Internet 53) Is a set of various functions such as trackback and update notification provided by a mechanism that also has hardware, web tools, protocols, etc.

Next, a message between the spatial information server 1 and the blog site 3 shown in FIG. 5 will be described. Here, the posting API 29 is a message from the spatial information server 1 to the blog site 3 and is an API for posting a blog entry, and specifications such as metaWeblogAPI are used. The update notification 30 is a message for notifying the spatial information server 1 of the update of the blog entry 8 acquired by the blog site 3, and specifications such as WeblogUpdatePing are used. Further, the link 31 is linked to the spatial information server by the URL of the balloon entry 8 set in the balloon definition information in the rain database 7 and the URL of the balloon search unit 24 of the spatial information server 1 set in the balloon entry 8. It indicates that the balloon database 7 of 1 and the blog entry 8 are related to each other (or state). Next, the blog site 3 shown in FIG. 5 will be described in detail.

Blog site 3 is a web site for linking to user-powered S-balloons to collect location information about the balloon definition space area, and includes blog entry 8, existing blog system 28, and spatial information plug-in 27. Is configured. The blog site 3 is opened by the user in advance before the user registers the balloon using the mobile terminal 2 and the spatial information server 1.

[0106] The blog entry 8 is generated for the balloon of the spatial information server 1. The category of this blog entry 8 is set to the same value as the category set for the balloon, and the first few lines of the content include part of the balloon definition information such as the balloon name and center coordinates, and the balloon of the spatial information server 1. URL power of search unit 24 Set when generated by spatial information server 1.

[0107] The existing blog system 28 demonstrates the existing functions provided by the blog service provider provider. In other words, blog site 3 can add its own functions using plug-ins!

The spatial information plug-in 27 is provided with a posting API 29 and an update notification 30 to add functions necessary for cooperation with the spatial information server 1 to the blog site. In general, providers and blog tools that provide blog services often have a posting API 29 and update notification 30, but blog sites that do not have them use this spatial information plug-in.

[0108] In addition, this blog site 3 is the other blog site (second blog site) 4 that notifies the mobile terminal 2 of the search result of the service information and the trackback or comment addressed to the balloon entry 8. Send URL.

On the other hand, the other blog site 4 is a blog site opened by a user who has, as blog entry 9, location information regarding the spatial area defined by the balloon where blog entry 8 is linked to blog site 3. The other blog site 4 and blog site 8 are linked to each other by trackback.

[0109] This trackback is a function of the system 100 that enables mutual reference of information between blog entries. In other words, this mechanism called trackback Entries 8, 4 and 8, 36 can be referred to each other.

FIG. 6 is a diagram for explaining the track back. The blog sites A and B shown in FIG. 6 are established by a user A on the reference side and a user B on the reference side. Here, if user B is interested in an article or topic displayed on user A's blog site A, user B adds an opinion or impression to the article cited and quoted to blog site B. indicate. In addition, as an etiquette in the network, user B asks user A, “User B quotes an article on blog site A and comments on that article on user B's blog site B. (This notification is called Track Knock Ping). On the other hand, when user A receives and approves the notification, user A sets a reverse link to the article on user B's blog site B. User A who is tracked back can also choose to reject the trackback notification.

Accordingly, a bidirectional link can be easily set between the blog entries A and B of the user A and the user B. In addition, the article power of user A, for example, N (N represents a natural number of 2 or more) is quoted on each blog site. N blog entries with a common topic Gather on A's blog site A.

Furthermore, the track back in the system 100 will be described in detail.

[0111] FIGS. 7 (a) and 7 (b) are diagrams showing an example of a trackback according to an embodiment of the present invention. Blog entry 9 (Fig. 5) sends the request shown in Fig. 7 (a) (HTTP—POST request) to Blog entry 8 (Fig. 5). In this request, the track knock information to be registered (for example, blog entry title, URL, blog name, summary, etc.) is written as a parameter. Upon receiving the notification, the blog entry 8 returns the response shown in FIG. 7B to the blog entry 9 in XML format when the trackback information is successfully stored. This response describes the success or failure of the trackback information and the message.

[0112] Blog entry 8 and blog entry 37 shown in FIG. 5 are both blog entries linked to a balloon. These blog entries 8, 37 force are linked together by trackback 32 because both linked nolanes are identical or identical in real 3D space. It is defined in various places.

When the blog entry 8 linked to the lane is updated by the trackback 32, the update information 30 notifies the spatial information server 1 linked to both parties, and the spatial information server 1 that receives the notification receives the trackback information. It is possible to refer to the balloon entry linked using the trackback to the rain entry 8 linked to the spatial information server 1 itself.

As a result, the spatial information server 1 obtains the URL of the balloon search unit of the spatial information server 6, and the spatial information server 6 obtains the URL of the balloon search unit 24 of the spatial information server 1. Set as definitions and be linked to each other.

Next, the blog service (a service that provides blog use) will be described in detail. FIG. 8 is a diagram for explaining RSS. Blog site A and blog site B shown in FIG. 8 represent user A's blog site A and user B's blog site B, respectively, and news site A displays the headline of the article. Here, news site A writes an article on youth site's own blog and converts the article into XML data. User A then quotes an article written on news site A, blog site B, etc., displays the quoted article on blog site A, or links to news site A! /

[0114] This functionality is a summary provision function called RSS feed, which is one of the functions provided by the blog service. In more detail, this RSS feed now provides a summary of -use site A to user A who has accessed news site A, using metadata called RSS.

Metadata is data that describes information about a website. For example, a search engine or the like assigns metadata to information data collected from a large number of websites and stores it in a storage device. Thereby, the user can remove unnecessary information data and acquire accurate information data.

[0115] RSS is also a structured description of metadata such as Web page titles, addresses, headings, summaries, and update times, and has an XML-based format. On the other hand, the RSS page itself is not suitable for browsing. Software that has an RSS reader function is installed to browse information data.

[0116] In this way, user A or the like collects new arrival information using an RSS feed, and ranks the ranking according to the popularity of each category on a large number of websites, for example. Is done. In addition, tools such as the RSS reader 18 that automatically notifies the mobile terminal 2 of new information that has been automatically acquired have been enhanced, making it easier for users to find the information they need.

[0117] As described above, the system 100 is a combination of the information providing service for the mobile terminal 2 and the blog service, focusing on the information usage and the mechanism for gathering information, which are the characteristics of the blog. is there. In addition, the system 100 provides a mechanism in which the information transmission place where the user stands is represented by one blog entry.

In addition, the service contents provided by the system 100 are as follows: (i) The place where the user stands can be defined using a balloon in a virtual space (a solid representing a virtual space range), and (ii) Anyone can easily The location information of the place where the user stands can be obtained and a blog entry linked to the balloon and the balloon can be created, and (iii) the location-dependent information dispatch point can be set freely. Here, if there is another user who has already obtained information about the location, the system 100 creates the other user's information as a blog entry and links the trackback to the blog entry linked to the balloon. As a result, blog entries with information about the location gather in the balloon.

[0118] On the other hand, as in the past, a provider providing an information distribution service may install a balloon. Even in this case, the user who uses the information provided by the operator can add the information he / she knows to the operator's blog entry using comments or trackbacks.

Normally, in the blog service, when a comment or trackback is performed on a blog entry, the owner is notified of the blog entry by e-mail or the like, and the comment or trackback is unintentional at the discretion of the blog site owner. It is possible to avoid this. [0119] The above balloon is a virtual solid defined using position information technology such as GPS positioning. For this reason, since communication means such as a mobile phone can be used widely for communication between the user and the location information system 100, it is not necessary to install an actual device on the spot when the balloon is installed. In recent years, the number of mobile terminals 2 such as mobile phones on which high-precision GPS receivers 11 are mounted is increasing, so that balloon searches using the mobile terminals 2 are easy.

[0120] On the other hand, at present, there are areas where GPS positioning cannot be used, such as indoors, and not all mobile terminals 2 can use high-precision location information. Until the technology that can be used for any mobile device 2 that covers those areas appears, balloons are also registered from mobile devices 5 that do not have location information positioning function, and can be searched using the balloon name Thus, the system 100 needs to have a function.

[0121] Hereinafter, messages in the system 100 will be described in detail.

First, a balloon registration method for the spatial information server 1 will be described with reference to FIGS. 9 (a) and 9 (b). FIGS. 9 (a) and 9 (b) are diagrams for explaining a balloon registration method to the spatial information server 1 according to an embodiment of the present invention, respectively, in the case where a balloon registration HTTP—POST request is used. An example is displayed.

[0122] Here, the balloon registration unit (Fig. 5) of the portable terminal 2 transmits the HTTP-POST request shown in Fig. 9 (a) to the URL of the balloon registration unit 26 of the spatial information server 1. This balloon registration HTTP—POST request specifies the center coordinates (latitude and longitude) of the balloon to be registered, the coordinate positioning system, balloon diameter (radius in the case of a spherical balloon), balloon name, and so on.

On the other hand, when the registration of the balloon is successful, the spatial information server 1 writes the balloon data registered in the NVML format to the portable terminal 2 and writes it back in the response shown in FIG. 9 (b).

Next, a balloon search method from the spatial information server 1 will be described with reference to FIGS. 10 (a) and 10 (b).

[0124] Figs. 10 (a) and 10 (b) are diagrams for explaining a balloon search method according to an embodiment of the present invention. The mobile device 2 uses the balloon search URL of the spatial information server 1 The HTTP—POST request shown in Fig. 10 (a) is sent. This HTTP—POST request specifies the coordinates (latitude and longitude) of the lower left and lower right of the search range (rectangle), the coordinate positioning system, and the output format (NVML is the default).

[0125] Then, when the spatial information server 1 detects the balloon data, a response written in NVML format (when the opf of the request is NVML) to the portable terminal 2 (Fig. 10 (b ) )return it. Specifically, information about the notation of positioning system etc. is written between <head>, <Zhead>, and <point> element of <guide> element between <body>, <Zbody> Balloon definition information (center coordinates, range (area attribute), URL of blog entry, etc.) is written. Also, guide> elements are returned to the mobile terminal 2 by the number of detected balloons. The elements of balloon data that are not in the NVML specification are described by <note> elements.

FIG. 11 (a) is a diagram illustrating an example of a posting API request according to an embodiment of the present invention, and FIG. 11 (b) is an example of a posting API response according to an embodiment of the present invention. is there. This API for posting is an API for posting a blog entry. For example, Blogger API and metaWeblog API are known.

Blog tools and blog services have many mechanisms for linking between different systems and are implemented using XML—RPC. This XML—R PC is a protocol for executing remote procedure calls over the Internet 53, the message is an HTTP—POST request, and the request body is XML. Results are also returned in XML format.

[0127] Figures 11 (a) and 011 (b) show metaWeblog A

API for posting new articles by PI, metaWeblog.newPost is shown as an example.

Posting blog site ID (blog ID: ID assigned by the blog system! /, ID), username and password for posting to the blog site, the content of the posted article, and whether or not to publish Etc. are issued as parameters. Here, when posting is successful, the ID of the article assigned by the blog system is returned as a response.

Next, the update notification method will be described with reference to FIGS. 12 (a) and 12 (b).

FIGS. 12 (a) and 12 (b) each illustrate an update notification method according to an embodiment of the present invention. It is a figure for doing. These update notifications shown in FIGS. 12 (a) and 12 (b) are also sent from the spatial information plug-inker of the blog site 3 to the entry update detection unit of the spatial information server 1.

[0129] Similar to the posting API, the update notification is provided as a mechanism for linking many blog tools and blog services between systems, and is implemented using XML-RPC. In this way, new information from the blog site is notified to other servers (spatial information server 6 etc.). Note that weblogUpdates Ping Force S has this update notification function.

[0130] Blog site 3 notifies the request shown in Fig. 12 (a) using the updated blog entry title and URL as parameters, and when spatial information server 1 receives the notification, it notifies the notification success and acknowledges the notification. A response with a message as a parameter is returned (Fig. 12 (b)). Here, since the information to be notified is only the title and URL of the blog entry 3, it is hoped that the spatial information server 1 notifies the blog site 3 of the request and acquires it in order to confirm the updated contents. Better ,.

[0131] If the blog entry is updated by trackback, and MovableType is used as the blog tool, blog site 3 sends a mt. GE T TrackbackPings request via XML—RPC and sends the trackback Ping URL. To get.

Next, a method for obtaining a summary of a blog entry will be described with reference to FIGS. 13 (a) and 13 (b).

FIGS. 13 (a) and 13 (b) are diagrams for explaining a summary acquisition method according to an embodiment of the present invention. Here, many blog tools output blog information to an RSS file, and a summary can be obtained by using the GET request shown in Fig. 13 (a). . The following is an example of RSS file acquisition using a blog tool called MovableType.

[0133] When the blog entry is tracked back, the trackback information power to the entry is output in SS format under the archive directory, as “Article ID. XMLJ”, so mobile device 2 sends a GET request to this URL As shown in Fig. 13 (b), the blog entry summary and the blog entry trackback destination blog are obtained. The entry summary is output in RSS format.

With this configuration, the mobile terminal 2 accesses the blog entry 8 using the URL of the blog entry 8 included in the result 34 received from the spatial information server 1. The data acquired from the blog entry 8 is in the RSS format 35 and is displayed by the RSS reader 18 of the mobile terminal 2. If the blog entry 8 is linked to the blog entry 9 of another blog site 4 with the trackback 32, the URL of the blog entry 9 is also displayed in the RSS reader 18, so refer to the blog entry 9. be able to.

[0135] Also, when the mobile terminal 2 acquires balloon definition data from the spatial information server 1 using the balloon search unit 16, the mobile terminal 2 acquires a wide range of data at once, and the acquired data is stored in the balloon event management unit 15 To detect the balloon in the vicinity of the mobile terminal 2 to reduce the number of communication with the spatial information server 1 and notify the user of the URL of the balloon blog entry detected inside the mobile terminal 2. Thus, information can be presented in a push-like manner.

[0136] Furthermore, when the spatial information server 1 generates the blog entry 8 linked to the balloon, the balloon search unit 24 of the spatial information server 1 can be registered in the blog entry 8 that simply registers the URL of the blog entry 8 in the balloon database 7. Register the URL of.

This makes it possible to refer to the spatial information server 1 from the blog entry 8 side, but is registered in another spatial information server 6 in the geographical vicinity of the balloon registered in the spatial information server 1 !, If the blog entry 37 of the balloon is tracked back to the balloon entry 8, the space information server 1 is notified by the update notification. Upon receiving the update notification, the spatial information server 1 refers to the trackback blog entry, acquires the balloon search URL of the spatial information server 6 described therein, and registers it in the balloon definition information.

[0137] In this way, the balloon search unit 24 of the spatial information server 1 is used to transmit and receive the URLs of the other spatial information servers 6 together with the balloon definition information detected by the spatial information server 1. It becomes possible to search balloons from the spatial information server 6.

The spatial information server 1 enables the balloon search from the portable terminal 5 that does not have the position information function by the search extension function unit 22. This mobile device 5 does not have a location information function. Therefore, the user transmits a name representing his / her location to the spatial information server 1, and the spatial information server 1 that receives the name searches the balloon database 7 for all balloons having the name including the entered name, Send to mobile device 5.

[0138] On the other hand, the user of the mobile terminal 5 may select a balloon and refer to the blog entry linked to the balloon. However, the name of the selected balloon and the definition position of the none are the center. The search range can be searched again with the spatial information server 1 as input information, and surrounding balloons can be found.

In addition, the spatial information server 1 can set the lifetime of the balloon when registering the balloon, and can delete the information when the deadline has come using the northern state management unit 23. As a result, the service provider using the spatial information server 1 can charge on the condition that the life of the balloon is extended.

Next, with reference to FIG. 14 (a), FIG. 14 (b) -FIG. 17, a mode in which a plurality of spatial information servers 1 etc. in the system 100 are connected will be described.

The spatial information servers 1, 6 and so on in Fig. 5 above are provided independently, but can be connected in the form of V, in other words, a "row of beads" by the connection method described below.

FIG. 14 (a) shows a combination of blog site A and spatial information server A according to an embodiment of the present invention. In this state, blog site A and spatial information server A shown in FIG. Figure 14 (b) shows the connection between blog site B and spatial information server B.

[0140] In Fig. 14 (b), this service information provision method first supports each of a plurality of 3D space range information corresponding to the actual 3D space and a plurality of addresses for obtaining service information. A blog site A that has a spatial information server A that accesses a balloon database that holds multiple attached balloon data is set up.

Then, blog site B that holds balloon data registered in duplicate in the actual 3D space corresponding to the 3D space range information of the lane data stored in blog site A is installed.

[0141] Next, the blog entry (first balloon entry) A and the blog entry (second balloon entry) B are set in a state where they can be cross-referenced. This cross-reference is Be made. The process up to this point corresponds to the part marked “1” shown in FIG. Subsequently, update notification is sent to the blog entry A, the blog entry B, and the blog site A's spatial information server A and the blog site B's spatial information server B (see the part marked “2”).

[0142] Furthermore, spatial information server A and spatial information server B obtain the balloon search URL of spatial information server B and the balloon search URL of spatial information server A, respectively (see the part labeled "3") .

Spatial information sano A and spatial information server B then link and register the balloon search URL and balloon search URL in the balloon database of spatial information server A and the balloon database of spatial information server B, respectively (“4” and (See the attached part).

In this way, the two spatial information servers A and B provided independently are connected.

Next, FIG. 15 is a diagram for explaining the connection of two blog sites according to an embodiment of the present invention.

Here, in a state where spatial information server A and spatial information server B are connected, blog site C that is further registered in balloon entry B and the actual three-dimensional space corresponding to the above three-dimensional spatial range information. Balloon entry C is linked to each other.

[0144] Balloon entry B, balloon entry C, and force [0144] Update information is sent to spatial information server B and spatial information server C provided at blog site C, respectively. The balloon search URL of the spatial information server C and the balloon search URL of the spatial information server B are acquired.

Further, spatial information server B and spatial information server C record the balloon search URL and the second balloon search URL in the balloon database of spatial information server B and the balloon database of spatial information server C, respectively.

[0145] In this way, three types of spatial information servers A—C are associated.

Next, FIG. 16 is a diagram for explaining the connection of three blog sites according to an embodiment of the present invention.

Here, in a state where spatial information server A, spatial information server B, and spatial information server C are connected, balloon entry A and the actual information corresponding to the above-described three-dimensional spatial range information are further included. Balloon entry D of blog site D registered in the 3D space is linked to each other.

[0146] Balloon Entry A, Balloon Entry D, and Force [0146] Update information is sent to Spatial Information Server A and Spatial Information Server D installed in Balancing Site D, respectively. Acquires the balloon search URL of spatial information server D and the balloon search URL of spatial information server A, respectively.

Spatial information sano A and spatial information server D record the balloon search URL and balloon search URL in the balloon database of spatial information server A and the balloon database of spatial information server D, respectively.

[0147] In this way, four blog sites are linked.

FIG. 17 is a view for explaining a method of searching for connected spatial information servers AD according to an embodiment of the present invention.

In the state where spatial information server A, spatial information server B, spatial information server C, and spatial information server D shown in FIG. 17 are connected, mobile terminal 2 receives the URL and spatial information of balloon entry A from spatial information server A. Get the URLs of Information Server B and Spatial Information Server C.

[0148] Then, the mobile terminal 2 obtains the URL of the rain entry B and the URLs of the space information server C and the space information server C from the space information server B, and sends the URL of the balloon entry C from the space information server. The URL is acquired, and the URL of the balloon entry D is acquired from the spatial information server D.

As described above, in the present system 100, the spatial information servers A to D at a plurality of locations are connected, and the mobile terminal 2 can access any sano of the spatial information servers A to D. Service information can be provided even if you join a different company.

[0149] The detailed operation of the system 100 will be described in detail below.

FIG. 18 is a diagram showing a sequence for explaining a balloon entry generation method according to an embodiment of the present invention. Each of A1 to A16 shown in FIG. 18 represents one message or a plurality of message groups.

The user presses the “balloon registration button” provided on the mobile terminal 2 or displays on the display unit 42. Select and execute the displayed “Balloon Registration” to start the balloon registration application (Message Al).

In this way, information about the location can be obtained from user C who does not have a blog site.

[0179] Next, a method of using the user with such a configuration will be described.

FIG. 24 is a diagram for explaining a method of using the information providing service according to an embodiment of the present invention. This is shown in FIG. 24, and those having the same reference numerals as those described above represent the same items.

The system 100 shown in FIG. 24 has a spatial information server and blog sites (Web servers) 10 and 20 and users who use these servers (spatial information servers, blog sites 10 and 20). Three types of players A, User B, and User C are displayed. As an example of a method for acquiring service information, a user C enters service information such as a restaurant menu in the real space position where the user C stands, and the user B's blog entry created on the blog site 10 By accessing the URL, it is possible to obtain from the blog entry of user B created on the blog site 20.

[0180] Here, the blog sites 10 and 20 are for creating blog entries to be described later for the users A and B, respectively, and are software that provides a blog service to each user A-C. It is. Both softwares that function as blog sites 10 and 20 are installed on, for example, workstations, personal computers (hereinafter referred to as workstations). Both pieces of software may be installed on separate workstations, installed on the same workstation, or distributed to a plurality of storage devices connected to the Internet.

[0181] The blog sites 10 and 20 are both the starting top page (start page, portal site) and multiple web pages attached to the top page (pages provided on the World Wide Web). ).

Next, the user A is a business operator who creates balloons in the spatial information server 1, for example, the owner of the balloon XI for the user A himself and the balloon X2 for the user B. In addition, the user c is a customer who acquires service information of the location by referring to the blog entries of the user A and the user B through the balloon. User B is an advertiser who advertises service information such as store menus. This user B has a balloon

Advertises service information at a location in (or around) the real space corresponding to the virtual space in which XI and X2 are created.

[0182] (i) Creating balloons and blog entries

First, user A creates balloons for user A and user C in the spatial information server. Then, the balloon registration unit of the spatial information server creates a blog entry for user A on the program site 10 using the posting API. The blog entry for user A is created when, for example, a fee is obtained from user A who registers balloon XI or the like in the user B force space information server, which is a provider. User A's Blog Birds can also be created by individuals.

[0183] (ii) Link of service information to balloons by other users

On the other hand, user B determines in advance the blog site for advertising, among the many blog sites including blog site 10. When User B determines the blog site 10, it tracks back and links User B's own blog entry to the blog entry linked to User A or User A's balloon XI.

[0184] As a result, the service information from user B to balloon XI is linked, and the service information is collected in the spatial information server.

(iii) Reference of service information via balloon by customer user C

User C accesses user A's balloon XI and uses the user A's blog entry and user B's blog entry to easily refer to or obtain service information.

[0185] Then, during the movement, the user C detects that the lane XI is registered at the position of the user C by pushing or pulling. User C queries the spatial information server for the search or marking of Lane XI by this detection.

Then, when the spatial information server searches balloon XI and finds user A's blog entry, it accesses user A's blog entry and obtains user B's URL.

[0186] Subsequently, link information is returned from the blog site 20 to the blog site 10, and notified to user C. User C accesses User B's URL and obtains the desired service information.

In this way, service information related to the location is collected by collaboration between user A and user B. In addition, user A can provide service information to user C, user B can perform appropriate advertisement according to the location, and user C can acquire desired service information.

[0187] A service in which the balloon definition information is made into a database and the server system sends a URL based on location information from the mobile terminal 2 can obtain information such as buildings within the range that the user can see. Service information can be obtained based on a sense of consciousness. On the other hand, if the user is in a place where a user is present and the information is held on the rooftop of a building in another city away from that place, it is difficult to use this search method.

[0188] On the other hand, in the service information providing system 100, using the feature that a large amount of information is automatically collected on the blog site, the mobile terminal 2 can connect to the desired blog via the spatial information server. Since the blog entry of the site is accessed and service information about various places is concentrated on the blog entry, the mobile terminal 2 can obtain service information at various places without moving the place.

[0189] Therefore, for example, when the user is standing in front of a department store near A station on the loop line, it is possible to obtain menus of restaurants at department stores near B station and department stores near C station. In other words, according to the present invention, “information about a place” such as a restaurant menu of a department store near B station can be easily obtained.

In addition, the mobility of the mobile terminal 2 and the service information concentration function resulting from the blog are linked in this way, allowing the user to communicate “anytime”, “anywhere”, and “everyone”. In addition, service information can be acquired “anywhere”. Furthermore, according to the present invention, it is possible to obtain service information “whatever service provider the user subscribes to”.

[0190] (B) Modification

If the user is in a relatively small place such as a building or room, location information can also be obtained using triangulation instead of GPS. Specifically, the mobile terminal 2 is provided with a light Z sound wave transmitter for transmitting light and sound waves, and at least three sets of ultrasonic Z infrared receivers are provided on the ceiling of the room. The ultrasonic waves and infrared rays from the portable terminal 2 are received, the difference between the reception times of the ultrasonic waves and infrared rays is measured, and the position of the portable terminal 2 is specified based on the time difference!

[0191] Also, simple location information can be obtained using RFID (Radio Frequency-Identification).

Furthermore, the mobile terminal 2 can acquire the azimuth and the tilt angle as position information in addition to the latitude, longitude, and altitude. For example, a tilt sensor and an azimuth sensor can be provided. Here, the tilt sensor measures the tilt angle of the horizontal line force of the mobile terminal 2, The direction sensor measures the direction by detecting geomagnetism.

[0192] Instead of the above URL, URI (Uniform Resource Identifier, Uniform Resource

'Identifiers' or URNs (Uniform Resource Names) can be used as addresses.

Here, URI is a standard that extends URL and is used to identify data on the Web using a unique name. This URI assigns protocol name http, server name, directory name, and file name to data on the Web.

[0193] (C) Other

The present invention is not limited to the above-described embodiments and modifications thereof, and various modifications can be made without departing from the spirit of the present invention.

Industrial applicability

[0194] As described above in detail, according to the present invention, service information such as a building in the field of view can be automatically obtained at the place where the user stands, and the user can be the same at the place. Service information provided at other locations or locations can be obtained using other access points, and access restrictions and efficient hardware use are possible. Service information provided at various locations can be obtained.

[0195] In addition, since an information transmission point can be flexibly set at a desired place or position, information at any place can be registered, and the probability of obtaining useful information is dramatically increased. As a result, an increase in the number of users of information providing services based on location information and an expansion of the yard are expected, and the present invention can be expected to become a basic technology.
