Description

  The present invention relates to an Internet connection device that connects a mobile terminal to the Internet, a positioning system that includes a mobile terminal that measures a current position based on radio waves output from GPS satellites, and an information output that provides various information to the mobile terminal. It is about the system.

  As a positioning system of this type, a positioning system including a position detection device that measures the current position based on radio waves output from GPS satellites is disclosed in Japanese Patent Laid-Open No. 10-31061. In this case, in this type of positioning system, the position detection device (GPS positioning terminal) performs positioning processing using the satellite position estimation data acquired from the GPS base station, thereby reducing the time required for positioning processing immediately after startup, for example. doing. Therefore, in this positioning system, as shown in FIG. 2 of the publication, the position detection device is configured to include a mobile phone 3 for connecting to a GPS base station. Meanwhile, the GPS base station outputs current time information, GPS satellite orbit information (satellite position estimation data), and position information about the current position of the GPS base station to the position detection device.

In this positioning system, the GPS receiver 6 requests the GPS base station to transmit information via the mobile phone 3 when the position detector is powered on. In response to this, the GPS base station outputs current time information, GPS satellite orbit information, and base station position information. On the other hand, in the position detection device, the GPS receiver 6 measures the current position of the position detection device based on each information output from the GPS base station. In this case, in this type of positioning system, in order to determine the current position using the satellite position estimation data, it is necessary for the position detection device to grasp the approximate current position (rough position). Therefore, the GPS receiver 6 performs the positioning process using the position specified based on the position information output from the GPS base station (that is, the position of the GPS base station) as the approximate position of the position detection device. As a result, the current position of the position detection device is measured, and the current position is displayed, for example, on the display unit.
Japanese Patent Laid-Open No. 10-31061

  However, the conventional positioning system has the following problems. That is, in the conventional positioning system, the GPS receiver 6 is connected to the GPS base station via the mobile phone 3 to acquire the current time information, the GPS satellite orbit information, and the base station position information. Using the position information (position of the GPS base station) as the approximate position of the position detection device, positioning processing based on the radio wave output from the GPS satellite is executed. In this case, in the conventional positioning system in which the position detection device is connected to the GPS base station via the mobile phone 3, the GPS may be connected to a GPS base station far from the actual position of the position detection device. Therefore, when positioning is performed using the position information output from the GPS base station as the approximate position of the position detection device, the current position may be determined based on a position far from the actual position of the position detection device. For this reason, the conventional positioning system has a problem that it is difficult to accurately measure the current position of the position detection device.

  On the other hand, for example, Japanese Patent Application Laid-Open No. 2003-318991 discloses a hot service for providing an Internet connection service via a wireless LAN access point (Internet connection device) installed in an airfield, a hotel, a coffee shop, a store, a company reception room, or the like. A Spot (registered trademark) service system is disclosed. When this type of service network expands, a mobile terminal as a wireless LAN client (as an example, a wireless LAN disclosed in Japanese Patent Laid-Open No. 2002-247647 is used instead of the currently popular mobile phone, PHS, etc. It is expected that the slave station 1) in the telephone system will be widely used as a mobile communication terminal. However, in the above positioning system, even if a wireless LAN type telephone (so-called “IP phone”) is used instead of the mobile phone 3, the position detection device is connected to the GPS base station via the IP phone. In addition, a GPS base station that is far from the actual position of the position detection device may be connected. For this reason, there is a problem that it is difficult to accurately measure the current position of the position detection device in the same manner as when the mobile phone 3 is used.

  The present invention has been made in view of such a problem, and is an Internet connection apparatus that can output an accurate current position of a mobile terminal connected to the Internet, and a positioning system that can accurately determine the current position of the mobile terminal. And an information output system capable of providing various types of information corresponding to the current position to a mobile terminal connected to the Internet.

  In order to achieve the above object, an Internet connection apparatus according to the present invention includes a connection unit that connects a mobile terminal to the Internet, and position data generation that generates position data by measuring the current position based on radio waves output from an external device. Unit, a storage unit for storing the location data, and output of the location data to at least one of the information output device connected to the Internet and the mobile terminal by reading the location data from the storage unit Department.

  In this Internet connection device, the position data generation unit measures the current position based on the radio wave output from the external device to generate position data, and the position data output unit outputs the position data to at least one of the information output device and the mobile terminal. Is output. Therefore, position data close to the actual position can be provided to the information output device connected to the Internet and the mobile terminal within the connectable range. In this case, since the connectable range of the mobile terminal to the Internet connection device is extremely narrow, what is a conventional positioning system that outputs position information to a position detection device connected to a GPS base station via the mobile phone 3? In contrast, position data (position information) close to the actual position of the mobile terminal can be provided. Therefore, for example, a mobile terminal having a GPS positioning function can generate position data close to the actual position based on this position data, so that the current position can be accurately measured. In addition, for example, a message associated with the actual location of the mobile terminal can be distributed to the mobile terminal by the information output device that has received the location data output from the Internet connection device.

  Further, in the Internet connection apparatus according to the present invention, in the Internet connection apparatus described above, the storage unit stores broadcast station data for respectively specifying positions of a plurality of public broadcast station facilities as the external apparatus, The position data generation unit specifies the position of the public broadcasting station facility that outputs the radio wave based on both the broadcasting station data and the radio wave, and measures the current position based on the specified position. The position data is generated.

  In this Internet connection device, the position of the public broadcasting station facility that outputs the radio wave received by the position data generation unit is specified based on both the broadcasting station data and the received radio wave, and the specified position (public broadcasting station facility Position data is generated based on the current position. Accordingly, since the current position of the Internet connection device can be specified only by providing a relatively inexpensive receiver, position data is provided to the mobile terminal while avoiding an increase in the manufacturing cost of the Internet connection device. Can do.

  Furthermore, in the Internet connection apparatus according to the present invention, in the Internet connection apparatus described above, the storage unit stores frequency data about the radio wave output by each public broadcast station facility at a position of each public broadcast station facility. Associating and storing as the broadcast station data, and the position data generation unit specifies the public broadcast station facility outputting the radio wave based on both the frequency data and the radio wave and the specified public broadcast station The position data is generated by measuring the current position based on the position of the equipment.

Therefore, the position data can be generated by specifying the current position of the Internet connection device with a relatively simple configuration.

  Further, in the Internet connection apparatus according to the present invention, in the Internet connection apparatus described above, the position data generation unit measures arrival times of the radio waves output by the plurality of public broadcast station facilities, and each of the public broadcast stations The distance to the facility is calculated, and the current position is determined based on the calculated distance and the position of each public broadcast station facility specified based on the broadcast station data, thereby generating the position data.

  In this Internet connection device, the position data generation unit measures the arrival time of radio waves output by a plurality of public broadcasting station facilities, calculates the distance from each public broadcasting station facility, and determines the current position based on the calculation result. Position data is generated by positioning. Therefore, the current position of the Internet connection device can be measured more accurately as compared with the configuration in which the current position is specified based on the frequency of the radio wave output from the broadcasting station. Therefore, position data closer to the actual position can be output to the mobile terminal and the information output device.

  Furthermore, in the Internet connection apparatus according to the present invention, in the Internet connection apparatus described above, the position data generation unit measures the current position based on a radio wave output from a GPS satellite as the external device, and the position data Is generated.

  In this Internet connection apparatus, the position data generation unit measures the current position based on the radio wave output from the GPS satellite and generates position data. Therefore, even when an internet connection device is installed in a mountainous area where it is difficult to receive radio waves output from public broadcasting station facilities, the current position can be measured and position data can be generated.

  In addition, the positioning system according to the present invention measures the current position based on one of the Internet connection devices described above and the radio wave output from the GPS satellite while being connected to the Internet via the Internet connection device. The mobile terminal; and an estimation data output device for storing satellite position estimation data for the GPS satellite and outputting the satellite position estimation data to the mobile terminal via the Internet, the Internet connection device comprising: The position data generated by the position data generation unit is output to the mobile terminal via the position data output unit, and the mobile terminal generates terminal position data based on the output position data, and Radio waves output from GPS satellites, satellite position estimation data, and Locate the present position based on the end position data. The satellite position estimation data according to the present invention includes not only orbit information (so-called almanac, ephemeris, etc.) for calculating the approximate position (estimated position) of the GPS satellite, but also various types of captured information added thereto. included.

  In this positioning system, the Internet connection device outputs position data to the mobile terminal, the mobile terminal determines the current position based on the output position data, generates the terminal position data, and uses the satellite position estimation data. Execute the process. Therefore, unlike a conventional positioning system that outputs position information to a position detecting device connected to a GPS base station via a mobile phone 3, the position close to the actual position based on the position data output by the mobile terminal Since data can be generated, the current position of the terminal can be accurately measured.

  An information output system according to the present invention includes any one of the Internet connection devices described above, the mobile terminal connected to the Internet via the Internet connection device and displaying a message based on received message data, And storing the message data in association with each position and outputting the message data to the mobile terminal, and the Internet connection apparatus stores the position data generated by the position data generation unit Output to the information output device via the location data output unit, and the information output device specifies the terminal current location of the mobile terminal connected to the Internet via the Internet connection device based on the location data And associated with the current location of the terminal The message data and outputs it to the mobile terminal that.

  In this information output system, the Internet connection device outputs position data to the information output device, and the information output device specifies the terminal current position based on the output position data, and is associated with the specified terminal current position. Output the message data to the mobile terminal. Therefore, various information associated with a position close to the actual position can be provided from the information output device to the mobile terminal.

Based on the processing result of the GPS processing unit 35, the accurate current time, etc., and stores it in the storage device 32, and also via the network N and the access point 2.

  The information center facility 4 is an example of an information output device according to the present invention, and includes a communication modem 41, a storage device 42, and a control device 43 as shown in FIG. The communication modem 41 receives the position data Dp0 output from the access point 2 and outputs it to the control device 43, and transmits the advertisement data Di to the mobile phone 1 under the control of the control device 43. The storage device 42 stores advertisement data Di, Di,...

  On the other hand, as shown in FIG. 6, the network N connecting the access points 2, 2,..., The management center facility 3 and the information center facility 4 is, for example, a concentrator line in which a plurality of access points 2, 2,.

In the following description, in order to facilitate understanding of the present invention, description of the concentrating station facility 51 and the relay station facility 52 is omitted, and these are collectively referred to as a network N.

  Next, a method for positioning the current position of the mobile phone 1 by the positioning system 10 will be described with reference to the drawings. In this positioning system 10, when the access point 2 is newly installed and the power is turned on, or when the power of the existing access point 2 is turned on again, the access point 2 performs positioning processing (position data). Dp0 generation and storage in the storage unit 24) is started. Specifically, the control unit 25 causes the receiving unit 23 to scan the frequency (which may be a channel: hereinafter, also simply referred to as “frequency”), and the radio broadcast signals Sr, Sr,. Broadcast signals St, St... Are received. In response to this, the receiving unit 23 notifies the control unit 25 of the frequencies of the received radio broadcast signal Sr and television broadcast signal St.

  Next, the control unit 25 outputs the radio broadcast signal Sr having the frequency received by the receiving unit 23 based on the broadcast station specifying data Ds stored in the storage unit 24 and the notification result of the receiving unit 23. The radio broadcast station facility 7 and the television broadcast station facility 8 that outputs the television broadcast signal St of the frequency received by the receiving unit 23 are specified. Next, the control unit 25 specifies the position where the specified radio broadcast station facility 7 and the television broadcast station facility 8 exist based on the broadcast station specifying data Ds. That is, it specifies based on both the radio wave of a broadcasting station and the broadcasting station specifying data Ds. Thus, as an example, the access point 2 is “located within the range of north latitude XX degrees XX minutes XX seconds, east longitude XX degrees XX minutes XX seconds to radius XX m", and so on. The installation location of the access point 2 (current position in the present invention) is specified. Subsequently, the control unit 25 generates position data Dp0 based on the identified current position, and causes the storage unit 24 to store the generated position data Dp0. Thereby, the installation (or restart) of the access point 2 is completed. By executing this positioning process by all the access points 2, 2... Installed in the available area of the positioning system 10, the storage unit 24 of each access point 2, 2,. The position data Dp0 that can specify the current position is stored.

  On the other hand, when the mobile phone 1 located within a range that can be connected to the access point 2 (in this example, within a radius of about 100 m) measures the current position, a predetermined operation of the operation unit 13 is performed. Operate the button. In response to this, the control unit 16 starts the current position positioning process. In this current position measurement process, first, the control unit 16 controls the wireless communication unit 11 to request the access point 2 to transmit data for specifying the current position. In response to this, at the access point 2, the control unit 25 reads the position data Dp0 from the storage unit 24 and controls the wireless communication unit 21 to cause the mobile phone 1 to output the position data Dp0. Next, the control unit 16 sets the position specified based on the position data Dp0 output from the access point 2 (that is, the position where the access point 2 is installed) as the current position of the mobile phone 1, and the current position. The position data Dp1 for is generated. In this case, since the range that can be connected to the access point 2 is extremely narrow, such as within a radius of about 100 m, the location of the access point 2 is defined as the current position of the mobile phone 1, so The error with respect to the position can be as small as about 100 m. Next, the control unit 16 stores the generated position data Dp1 in the storage unit 14 and requests the management center facility 3 to transmit the assist data Da.

  On the other hand, in the management center facility 3, when the mobile phone 1 is requested to transmit the assist data Da, the control device 36 reads the assist data Da stored in the storage device 32 and controls the communication modem 31. Thus, the assist data Da is transmitted to the mobile phone 1. Thereby, the latest assist data Da is stored in the storage unit 14 of the mobile phone 1. Next, in the mobile phone 1, the control unit 16 controls the GPS processing unit 12 to receive the GPS signal Sg output from the GPS satellite 9 and measure the current position of the mobile phone 1. At this time, the GPS processing unit 12 receives the GPS signals Sg, Sg,... Output from the respective GPS satellites 9, 9, and outputs the reception results (processing results) to the control unit 16. The control unit 16 measures the current position of the mobile phone 1 based on the reception result output from the GPS processing unit 12 and the assist data Da and position data Dp1 stored in the storage unit 14. Next, the control unit 16 reads out map data for the specified current position from the storage unit 14 and displays a map (not shown) in which a mark indicating the current position is drawn on a map based on the read map data. To display. Thereby, the user of the mobile phone 1 can recognize the current position.

  On the other hand, in the positioning system 10, when any mobile phone 1 or personal computer is connected to the access point 2, the advertisement data Di associated with the current location of the mobile phone 1 or personal computer is sent from the information center facility 4. The data is output and displayed on the mobile phone 1 or a personal computer. Specifically, for example, when the mobile phone 1 is connected to the network N via the access point 2, the access point 2 receives the position data Dp 0 read from the storage unit 24 and the connected mobile phone 1. Address data (for example, a global IP address) is output to the information center facility 4. In response to this, in the information center facility 4, the control device 43 specifies the current position of the access point 2 based on the output position data Dp0, and searches the storage device 42 to associate it with the current position. It is determined whether or not the existing advertisement data Di is registered (stored). At this time, when the associated advertisement data Di exists, the control device 43 reads the advertisement data Di from the storage device 42 and controls the communication modem 41 to output the advertisement data Di to the mobile phone 1.

  On the other hand, the mobile phone 1 receives the advertisement data Di via the network N and the access point 2, and at that time, the control unit 16 sends a message based on the received advertisement data Di (for example, “XX Super XX”). “Branch, special sale sale now being held!”) Is displayed on the display unit 15. In this case, the advertisement data Di stored in the storage device 42 of the information center facility 4 is registered (stored) in association with each area where the access points 2, 2,. ) Therefore, the control device 43 specifies the advertisement data Di associated with the installation location of the access point 2 connected to the mobile phone 1 and outputs the advertisement data Di to the mobile phone 1, so that it is displayed on the display unit 15 of the mobile phone 1. Displays an advertisement related to the current position of the mobile phone 1.

  As described above, according to the access point 2 in the positioning system 10, the current position is determined based on the radio broadcast signal Sr output from the radio broadcast station facility 7 or the television broadcast signal St output from the television broadcast station facility 8. The position data Dp0 is generated, and the position data Dp0 is output to the mobile phone 1 and the information center facility 4, so that the position information (position Data Dp0) can be provided. In this case, since the connectable range of the mobile phone 1 to the access point 2 is a very narrow range (for example, a radius of about 100 m), the location information is connected to the position detection device connected to the GPS base station via the mobile phone 3. Unlike conventional positioning systems that output, position information close to the actual position of the mobile terminal (such as the mobile phone 1) can be provided. Therefore, since the mobile phone 1 can generate the position data Dp1 close to the actual position based on the position data Dp0, the current position can be accurately measured. In addition, the advertisement data Di associated with the actual position of the mobile phone 1 can be distributed to the mobile phone 1 by the information center facility 4 that has received the position data Dp0.

  Further, the position of the radio broadcast station facility 7 or the television broadcast station facility 8 (public broadcast station facility) outputting the received radio broadcast signal Sr or the television broadcast signal St is set to the broadcast station specifying data Ds and the received broadcast signal Sr. , St, and the current position is determined based on the specified position to generate the position data Dp0, whereby the current position of the access point 2 is specified only by providing a relatively inexpensive receiver. Therefore, the position data Dp0 can be provided to the mobile phone 1 or the like while avoiding an increase in the manufacturing cost of the access point 2. Further, by specifying the positions of the radio broadcast station equipment 7 and the television broadcast station equipment 8 based on the frequencies of the received broadcast signals Sr and St and the received broadcast signals Sr and St, the configuration is relatively simple. The position data Dp0 can be generated by specifying the current position of the access point 2.

  Further, according to the positioning system 10, the mobile phone 1 generates the position data Dp1 based on the position data Dp0 output from the access point 2 and measures the current position, so that the GPS base station is connected via the mobile phone. Unlike the conventional positioning system that outputs position information to the position detecting device connected to the mobile phone 1, the mobile phone 1 can generate position data Dp1 close to the actual position based on the position data Dp0. The position can be measured accurately. Various information associated with a position close to the actual position can be provided from the information center facility 4 to the mobile phone 1.

  In addition, this invention is not limited to said structure. For example, in the access point 2 described above, the current position is specified based on the frequency of the radio wave output from the radio broadcast station facility 7 or the television broadcast station facility 8 and the broadcast station specifying data Ds. The configuration of the Internet connection device is not limited to this, and when a plurality of radio broadcast signals Sr, Sr,... And television broadcast signals St, St,... Can be received, for example, the access point 2 of the radio broadcast signals Sr, Sr,. Is measured for a plurality of radio broadcasting station facilities 7, 7,..., And the distance from each radio broadcasting station facility 7, 7,... Is calculated based on the positioning results. Thus, it is possible to employ a configuration in which the current position of the access point 2 is measured by the triangulation method or the like to generate the position data Dp0. Specifically, as an example, the distance between the broadcast station and the access point 2 is calculated based on the arrival time of the radio wave for the time signal output from each broadcast station at every hour, and the access point 2 is detected by the triangulation method or the like. The current position can be calculated. According to this configuration, the current position of the access point 2 can be determined more accurately as compared with the configuration in which the current position is specified based on the frequency of the radio wave output from the broadcasting station. Therefore, the position data Dp0 closer to the actual position can be output to the mobile phone 1 and the information center facility 4.
