Abstract

A positioning system includes a transmitter which transmits first unique information from a predetermined installation position and a mobile terminal which receives the first unique information transmitted from the transmitter. According to the first unique information received by the mobile terminal, the position of the mobile terminal is estimated. If a transmitter having forged first unique information is generated, a false position is accepted. Thus, there is a problem that a position information service unique to a predetermined position can be provided to a user not at a valid position. In order to solve the problem, a terminal transmits to a server, first unique information received by the terminal as information unique to the transmitter and a reference (second unique information) to decide whether the first unique information is from a valid transmitter installed at a valid position. The server derives information (third unique information) unique to the installation position of the transmitter from the received first unique information and compares the third unique information to the second unique information received from the terminal. If these are in a predetermined relationship, it is judged that the transmitter is at a valid position.

Technical field

TECHNICAL FIELD [0001] The present invention relates to the field of mobile radio communications, and more particularly to a system for specifying the position of a moving radio device.

Background art

[0002] In recent years, the need for high-accuracy location information has greatly increased, and positioning technology for identifying the position of a moving wireless device has been actively researched and developed, as represented by positioning using a GPS satellite. .

One positioning method is reference point positioning in which the position of a moving wireless device is the position of a fixed wireless device (such as a base station) that can transmit or receive a wireless signal. This reference point positioning can be easily introduced because a normal wireless communication system can be used. Therefore, in recent years, reference point positioning systems have been introduced as one of the value-added services for cellular and wireless LANs.

[0004] Here, cellular, wireless LAN, and the like are infrastructures that are installed mainly for communication, and the coverage of one base station is due to a trade-off between the ability to communicate over a wide area and the cost required for base station installation. It is stationed to be wide. On the other hand, if the coverage of this single base station becomes wide, the positioning accuracy will naturally decrease, so there are very few positioning services that can be provided only by reference point positioning such as cellular or wireless LAN.

[0005] In addition, there is a force S that uses a general GPS satellite as a high-accuracy positioning system. This is because the positioning accuracy is high outdoors, but the signal from the GPS satellite is blocked indoors. It cannot be used indoors for positioning services that require positioning accuracy of several meters or less. For this reason, a positioning system with higher accuracy than these positioning systems was required.

[0006] As a positioning system using reference point positioning with higher accuracy than these positioning methods, there are systems disclosed in non-patent documents; These are systems for positioning purposes, and infrastructure is laid for positioning. By introducing these positioning systems, it is possible to obtain highly accurate location information and provide location information services such as indoors. [0007] It should be noted that the reference point positioning includes a method of installing a reader that communicates position information with an environment-side server by holding a transmitter on the object whose position is to be acquired, and a position on the server where the position is to be acquired. There are two main methods: holding a reader that communicates information and installing a transmitter on the environment side.

Disclosure of the invention

Problems to be solved by the invention

[0009] Here, let us consider a method of installing a reader as a target for obtaining the latter position and a transmitter on the environment side. In this method, the position is specified based on whether or not the positioning target can receive a radio signal transmitted by a transmitter installed on the environment side. In addition, having information unique to the transmitter eliminates the need to connect to the network, so it can be introduced at a very low cost.

[0010] However, the fact that the transmitter does not need to be connected to the network means that the transmitter is moved to another location and used, or a transmitter that transmits the same signal as the signal transmitted by the transmitter is forged. Even if the transmitter is used, the system cannot determine whether the transmitter is moving or counterfeit, and even if the transmitter is not in the proper position, location-specific location information services can be provided.

[0011] As a specific example, description will be given using location-dependent content distribution, which is a service in a commercial facility. For example, let us consider a case where a commercial facility provides a service for distributing coupons when a customer comes to a location of a store for the purpose of visiting the customer. In order to provide this service, a commercial facility (store side) installed a transmitter on the environment side and received the signal of the transmitter power by using the mobile phone of the customer for whom the location was acquired. Suppose a mobile phone has built a service that receives coupon distribution from a server. [0012] However, since the transmitter installed on the environment side is not directly connected to the network, the transmitter is moved or the transmitter that transmits the same information as the information transmitted by the transmitter is forged, and the store Even if a transmitter is installed at a location physically distant from the location (for example, the store is in Tokyo and the installation location is offshore, etc.), the server cannot determine whether the transmitter is moving or forged. As a result, the customer can receive coupon distribution outside the store without visiting the store, which may result in a loss of commercial facilities.

There is currently no technique for guaranteeing the reliability of position information for the above-described problems.

BEST MODE FOR CARRYING OUT THE INVENTION

[First Embodiment]

A first embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a system configuration. System configuration: transmitter 100 for transmitting location information;! ~ 1003, mopile terminal 1011 ~; 1013, receivable area for location information transmitted by transmitter 1021 ~; 1023, radio base station 1031, communication of radio base station Possible area 1032, network 1041, sano 1042 power, etc. Then, transmitters 1001 to 1003 (also receiving area 102;! To 1023 are periodically sending location information, and receiving areas 1021 to 1023 When the end 1011 ~; 1013 is entered, the position information from the transmitter can be received.

FIG. 2 is a block diagram showing the configuration of the server 1042. Server 1042 includes receiving unit 10, third unique information deriving unit 20, comparison determining unit 30, storage unit 40 second unique information converting unit 5

It consists of 0.

[0028] The third unique information deriving unit 20 receives a signal (position information, second unique information, etc.) sent from the wireless terminal via the network 1041 and the wireless base station 1031; Received position information power Derived third unique information (information unique to the location of the transmitter)

[0029] The comparison / determination unit 30 compares the third unique information with the second unique information, and the received position information, etc. is correct! /, The correctness installed at the position! /, Information from the transmitter. Whether it is true or false is judged and processed.

[0030] The storage unit 40 stores a conversion table or the like for deriving the third unique information from the position information.

[0031] The second unique information conversion unit 50 receives the received second unique information (position information of the transmitter is the correct LV, correctness installed at the position, whether or not the information is from the transmitter) If the information used as the determination criterion) cannot be compared with the third unique information in the same format, the second unique information is converted into a format that can be compared with the third unique information.

[0032] When the second unique information can be compared with the third unique information in the same format, the second unique information conversion unit 50 is not necessary.

[0033] Next, using the flowchart in FIG. 3, the correctness of whether the position information from the transmitter is correct! / Is the information from the transmitter is confirmed. Thus, we will explain how to increase the reliability.

[0034] As described above, transmitters 100;! To 1003 regularly transmit location information to the reception areas 1021 to 1023, and the mono terminals 1011 to 1013 to the reception areas 1021 to 1023. When S is entered, location information from the transmitter can be received. Transmitter 1001 ~; When receiving location information from 1003, mopile terminal 1011 ~; 1013 is transmitter 1001 ~; in addition to location information from 1003, transmitter 1001 ~; The second unique information, which is information used as a criterion for determining whether or not the information is correct transmission capability, is also collected. Obtain (step 1101).

[0035] Here, the format of the position information from the transmitters 1001 to 1003 may be ID, coordinates, latitude and longitude, logical position information (vegetable floor, meat floor, etc.), and the like. The mopile terminals 1011 to 1013 notify the location information and the second specific information from the transmitters 1001 to 1003 to the server 1042 through the radio base station 1031 and the network 1041 (step 1102).

The server 1042 derives third unique information specific to the location where the transmitters 1001 to 1003 are installed from the notified location information from the transmitters 1011 to 1013 (step 1106), The notified second unique information is compared with the derived third unique information, and the notified positional information is correct, the correct installed at the position, and information from the transmitter. Whether it is true or not is judged (step 1103). If it is determined that the location information is from a transmitter at an unauthorized location, the service is processed for unauthorized use! / ヽ (step 1104), and the location information from the transmitter at an authorized location is used. If it is determined that there is a service, the service is processed for regular use (step 1105).

[0037] Here, the second unique information is used as a criterion for determining whether or not the position information of the transmitter is information from a correct transmitter installed at a correct position. It is desirable that the information is more difficult to forge and reliable than the location information from the transmitter.

[0038] Regarding location spoofing due to counterfeiting in the software in the mopile terminals 1011 to 1013, forgery is not possible by applying general authentication between the server 1042 and the software in the mopile terminal 101 ;! to 1013. Since a possible system can be constructed, it will not be described in detail here. As general authentication between the server 1042 and the mopile terminal; 1011 to 1013, the Simple & Secure (SAS) authentication method may be used.

[0039] In addition, forgery in the wireless network 1032 and the network 1041 can also be constructed by using a general encryption protocol between the server 1042 and the mobile terminals 1011 to 1013 to make forgery. I will not explain this in detail here because it is possible. As a general protocol between the server 1042 and the mopile terminal; 1011 to 1013, Secure Socket Layer (SSL) or the like may be used.

[0040] Further, in the present embodiment, the server 1042 has the transmitters 1001 to 1003; However, this function may be implemented in the mobile terminals 1011 to 1013.

[0041] Also, in the present embodiment, the server 1042 has the transmitters 1001 to 1003; the location information from the 1003 is correct! /, The correctness installed at the location! /, And whether the information is from the transmitter. The ability to explain how to implement the function to determine whether this is true This function may also be implemented in the mopile terminals 1011 to 1013.

[0042] Hereinafter, five examples of the present embodiment will be described with reference to the drawings.

[0043] [Example 1]

In the first embodiment of the present invention, an example will be described in which the basic service set identifier (BSSID) of a wireless LAN base station is used as the second unique information and the third unique information.

[0044] The configuration of the present embodiment includes a wireless LAN base station as the wireless base station 1031, a transmitter 100;

Consider an infrared transmitter as 1003, a notebook PC with a built-in wireless LAN interface and infrared interface as mopile terminals;

The operation will be described with reference to FIG.

[0046] First, the notebook PC receives the location information periodically transmitted from the infrared transmitter and the BSSID of the wireless LAN base station periodically transmitted from the wireless LAN base station (step 200 Do and The received location information and BSSID are notified to the server using the wireless LAN (step 2002).

[0047] In the present embodiment, the storage unit 40 of the server 1042 has a correspondence table between location information (eg, transmitter ID) of each transmitter and the BSSID of the wireless LAN base station that should be obtainable at that location. Is registered in advance! / (See Fig. 5).

[0048] Based on the notified position information, server 1042 uses a database held in storage unit 40 of server 1042, and at a position where an infrared transmitter that transmits the notified position information is installed. The BSSID that should be obtained is derived in the unique information deriving unit 2 (step 2006). Then, the BSSID (second unique information) notified from the notebook PC and the BSSID (third unique information) derived by the server are compared by the comparison / determination unit 30, and the position information notified by whether or not they match. It is determined whether or not is the position information from a legitimate infrared transmitter (step 2003). [0049] If, as a result of the comparison, the notified BSSID (second specific information) does not match the derived BSSID (third specific information), the notified position information is the position from an unauthorized infrared transmitter. (Step 2004), while the reported BSSID (second unique information) and the derived BSSID (third unique information) If there is a conflict, it is determined that the notified location information is location information from a legitimate infrared transmitter, and processing for regular use of the service is performed (step 2005).

FIG. 5 shows an example of the correspondence table stored in the server.

[0051] The example of this table is an example in which the correspondence between the location information from the transmitter (here, the transmitter ID) and the BSSID that can be acquired at that location is stored.

[0052] In addition, the BSSID of the wireless LAN base station to be notified is correct for location information, etc., and is a standard for determining whether the information is from the correct transmitter installed at the location. Since it is information, it is desirable that it is more reliable than position information from an infrared transmitter. In this respect, since the wireless LAN base station can perform bidirectional communication with the server and other management servers via the backbone network, it is easy to monitor from the server. It can be said that securing is easy.

[0053] Generally, in order to improve the BSSID reliability of a wireless LAN base station, confirm that the BSSID notification is from a legitimate wireless LAN base station. It is necessary to confirm whether it is in position. The following is a simple example of a method commonly used to improve BSSID reliability.

[0054] As an example of a method for confirming that the BSSID notification is from a legitimate wireless LAN base station, it is confirmed that the wireless LAN base station is legitimate and the BSSID notified to the server in step 2001 by the notebook PC. There is a method to confirm that you are connected to a regular wireless LAN base station with the same BSSID. In other words, if the BSSID notified to the server by the notebook PC is the same as the BSSID of the wireless LAN base station to which the notebook PC is connected, it can be said that the BSSID is that of a regular wireless LAN base station. An example of a method for confirming that a wireless LAN base station is legitimate is a method of authenticating with a server or another management server. In this method, a mechanism for performing authentication between the server or other management server and the wireless LAN base station is provided, and if the authentication is processed correctly, the wireless LAN base station is authorized. It is a method that can be confirmed as a thing. At this time, as the authentication method, for example, known shared key authentication or public key authentication can be used.

[0055] Next, four methods will be briefly described as examples of a method for confirming whether a regular wireless LAN base station is in a regular position. (1) Check if there is any change in the network configuration between the server and the wireless LAN base station. In this method, for example, the network configuration between the server (or other management server) server and the wireless LAN base station is maintained, and the configuration is periodically confirmed based on the configuration information. If the network configuration held by the server is different from the network configuration that is regularly checked, it can be determined that the base station is moved to the normal position! (2) Check if there is no contradiction in the combination of other wireless LAN base stations with which the notebook PC can communicate. (3) There is no contradiction in the combination of the signal strength of signals that the notebook PC also receives from other wireless LAN base stations. (4) Check whether the combination of radio wave propagation time with each wireless LAN base station measured by the wireless LAN base station is inconsistent! / Or not. In the above methods (2) to (4), the position of the wireless LAN base station is correct! / When the server is in the “wireless LAN base station combination list”, “field strength combination list”, The “combination list” is stored in advance, and when a list different from the combination can be acquired, it is temporarily determined that the wireless LAN base station may have been moved. Based on the location of the wireless LAN base station stored on the server or paper, the network administrator who has received the primary judgment goes to search for the base station and confirms whether it has been finally moved. It can be determined whether or not the LAN base station is in a regular position.

The above is an example of a method generally performed for improving the BSSID reliability.

[0057] In the first embodiment described above, the power S shown as an example using the BSSID of the wireless LAN base station connected as the second specific information and the third specific information S, the wireless LAN base to which the notebook PC can be connected The combination of the BSSID of the local station and the signal strength of the signal from the wireless LAN base station to which the notebook PC can be connected can be used as specific information.

In this embodiment, an example in which a wireless LAN base station is used as a wireless base station is shown, but a mobile phone base station may be used.

[0059] In addition, wireless L used in power communication, which shows an example using an infrared transmitter as a transmitter. Radio transmitters other than AN base stations (for example, wireless LAN transmitters, zigbee transmitters, specific power-saving radio transmitters, RFID transmitters, visible light transmitters, UWB transmitters, radio transmitters for mobile phones) may be used. A wireless LAN transmitter is assumed to be a device that transmits only location information, such as an infrared transmitter.

[0060] When using signals from other wireless transmitters, the mopile terminal must be equipped with a wireless interface that can receive the medium transmitted by the wireless transmitter used.

Yes

[0061] In addition, a power PDA, a business dedicated terminal, a mobile phone, or the like showing an example using a notebook PC as a mopile terminal may be used.

[0062] In this embodiment, the transmitter is combined with a radio base station used for communication, and the communicable area of the radio base station is more than the area where the position information from the transmitter can be received. There is a wide possibility. Under these circumstances, it is difficult to detect fraud using stolen or counterfeit transmitters within the communicable area of the same radio base station.

However, by utilizing this embodiment, the range in which fraud was possible can be limited from the entire world to the communicable area of the same radio base station, and the reliability of location information is improved. That's the power S.

[0064] As described above, in the first embodiment, the second unique information and the third unique information use the BSSID of the wireless LAN base station. If the derived BSSID and the notified BSSID are the same, the transmitter is determined to be in the proper position (illegal! /), And the service is used for regular use.

[0065] [Example 2]

In Embodiment 2 of the present invention, an example will be described in which wireless LAN signal time is used for the second unique information and coordinates are used for the third unique information.

[0066] The configuration of the present embodiment includes a wireless LAN base station as the wireless base station 1031, an transmitter 100;! To 1003, an infrared transmitter, a mopile terminal; 1011 to 1013, and a wireless LAN interface and an infrared interface. Think of a laptop with a built-in.

The operation will be described with reference to FIG.

[0068] First, the location information transmitted from the infrared transmitter and the wireless LAN signal is transmitted from the notebook PC. (Step 3001). Here, the wireless LAN signal time includes the radio wave propagation time between each wireless LAN base station notebook PC, the round-trip radio wave propagation time between each wireless LAN base station notebook PC, and the signal from the notebook PC. Use at least one of the time to reach the station and the time that the signal from each wireless LAN base station arrives at the laptop

[0069] Next, the notebook PCs 1011 to 1013 receive the location information received from the infrared transmitters 1001 to 1003 and the signal time acquired from the wireless LAN through the wireless LAN network 1

042 is notified (step 3002).

In this embodiment, the storage unit 40 of the server 1042 has registered in advance a correspondence table of position information (for example, transmitter ID) of each transmitter and coordinate information corresponding to the position (FIG. 7). reference).

[0071] Then, the third unique information deriving unit 20 of the server 1042 uses an infrared transmitter that transmits using the correspondence table stored in the storage unit 40 of the server 1042 based on the notified location information. Derived position (coordinates) to be installed! / Step (step 3007).

In addition, second unique information conversion unit 50 of server 1042 calculates a position (coordinates) using the notified time of the wireless LAN signal (step 3003). Here, the position of the notebook PC using the signal time is calculated by holding the positions of the wireless LAN base stations 1001 to 1003 in the storage unit 40 of the server 1042, and performing GPS positioning or wireless LAN positioning. This can be done using commonly used trilateration.

[0073] Specific examples of the positioning method include the following. The signal time is transmitted from the notebook PC to the server according to a predetermined order of wireless LAN base stations. The server that receives the time of each signal sends the signal times in a predetermined order. Therefore, which wireless LAN base station the time of each signal sent is the signal time of. Recognize. Next, the server calculates the distance from each wireless LAN base station to the notebook PC from the time of each received signal, and writes a circle with the distance from each wireless LAN base station as the radius. Then, these circles theoretically intersect at one point, and that point becomes the position of the notebook PC.

[0074] When the position of the notebook PC is obtained by the above method, the time of three signals is sufficient. [0075] If the number of wireless LAN base stations is large, when the notebook PC sends the signal time to the server, the BSSID of the corresponding wireless LAN base station may be sent together. It is done. If the number of wireless LAN base stations increases, the signal time for all wireless LAN base stations is sent from the notebook PC to the server, and positioning is performed even if positioning is performed using all the time information of these signals. The accuracy may not be improved drastically, but it may take a long time. In such a case, the time of the received signal is sent to the server by sending the required number of signal times and the corresponding BSSID of the wireless LAN base station to the server. This is because the position of the laptop can be measured.

[0076] If the signal time is transmitted from the notebook PC to the server in a predetermined order, the wireless LAN that has failed to measure the signal time in order not to upset the reception order in the server. For the signal time for the base station, some information indicating measurement failure must be sent to the server. On the other hand, if the BSSID of the wireless LAN base station corresponding to the signal time is transmitted, the server can receive the received signal without transmitting information about the wireless LAN base station that has failed to be measured. By referring to the BSSID received together, it is possible to determine which wireless LAN base station corresponds to the current time. Returning to the explanation of FIG. The comparison / determination unit 30 of the server 1042 has a fixed position (coordinates) calculated from the wireless LAN signal time by the second unique information conversion unit 50 and a position (coordinates) derived by the third unique information deriving unit 20. It is determined whether or not the location information notified by whether or not the relationship is satisfied (step 3004), and if it is determined that the location information is from an unauthorized infrared transmitter, The unauthorized use process is performed (step 3005), and if it is determined that the position information is from a legitimate infrared transmitter, the service is properly used (step 3006).

Here, as an example of means for determining whether or not the calculated position (coordinate) and the derived position (coordinate) satisfy a certain relationship, the calculated position (coordinate) and the derived position (coordinate) )) Is within a certain distance, it is determined that the position information is from a legitimate infrared transmitter, and if it is more than a certain distance, it is determined that the position information is from an unauthorized infrared transmitter. is there. Here, the fixed distance may be given a fixed value in advance, or positioning accuracy calculated by triangulation or the like may be used.

[0079] As another example of a means for determining whether the calculated position (coordinates) and the derived position (coordinates) satisfy a certain relationship, the server uses the derived position (coordinates) as As shown in the example of Fig. 8, a table describing the range information of the existing coordinates for each transmitter ID is stored in the storage unit 40 of the server 1042, and the calculated position (coordinates) is within the range of the derived position (coordinates). There is also a means to determine whether the location information is correct! /, Whether the information is correct from the transmitter! /, Or whether the information is from the transmitter! /.

[0080] If the position information that can be acquired from the infrared transmitter is originally a coordinate, the means of deriving the position (coordinate) is not necessary, and the position (coordinate) information acquired from the infrared transmitter should be used. I can do it. In this case, the server 1042 does not need to hold the tables as shown in FIGS.

[0081] Also, as described above in the second embodiment, when the BSSID of the wireless LAN base station 1031 is used, the BSSID of the wireless LAN base station 1031 used is the infrared transmitter 100;! It is desirable to have higher reliability than position information from The wireless LAN base station 1031 has a backbone network 1041 and is capable of bidirectional communication with the server 1042 and other management servers.

[0082] In order to improve the BSSID reliability of the wireless LAN base station 1031, confirm that the BSSID notification is from a regular wireless LAN base station, and whether the regular wireless LAN base station is in a regular position. It is necessary to confirm. Since this point is the same as that of Example 1, it will be briefly described below.

[0083] As an example of a method for confirming that the BSSID notification is from a legitimate wireless LAN base station, the wireless LAN base station is confirmed to be legitimate, and the notebook PC notifies server 1 042 in step 3001. There is a method to confirm that you are connected to a regular wireless LAN base station that has the same BSSID as the BSSID. An example of a method for confirming that a wireless LAN base station is legitimate is a method of authenticating with a server or another management server.

[0084] As an example of a method for confirming whether a regular wireless LAN base station is in a regular position, it is confirmed whether there is any change in the network configuration between the server and the wireless LAN base station. Check if there is no contradiction in the combination of other wireless LAN base stations with which the PC can communicate, and whether there is a contradiction in the combination of the signal strength of signals received from the other wireless LAN base station by the notebook PC! And confirming that there is no contradiction in the combination of radio wave propagation time with each wireless LAN base station measured by the wireless LAN base station.

[0086] In addition, a wireless transmitter other than a wireless LAN base station used in power communication that shows an example using an infrared transmitter as a transmitter (for example, a wireless LAN transmitter, a zigbee transmitter, a specific power-saving wireless transmission) Or transmitter, visible light transmitter, UWB transmitter, radio wave transmitter for mobile phone).

[0087] When using signals from other radio transmitters, a radio interface that can be received by the radio transmitter used in the mopile terminal needs to be installed.

[0088] In addition, the power S, an example using the time of the wireless LAN signal as the second specific information, the time of the signal of the mobile phone, and the time of the signal of the GPS satellite may be used. When using GPS satellite signals, the mopile terminal must have a GPS interface!

[0089] Further, a power PDA, a business dedicated terminal, a mobile phone, or the like showing an example using a notebook PC as a mopile terminal may be used.

In the present embodiment, an example is shown in which coordinates are used for the third unique information, but latitude and longitude may be used.

Further, in the present embodiment, the same wireless LAN signal time as the second specific information may be used as an example in which coordinates are used for the third specific information. When the wireless LAN signal time is used for the third unique information, the step of calculating the position (coordinates) from the wireless LAN signal time notified by the server in FIG. 6 (step 3003) Is omitted.

In addition, as an example of the correspondence table held in the server at this time, there is a table describing the arrival time of radio waves from each base station in each transmitter ID as in the example of FIG.

[0093] As described above, in the second embodiment, the wireless LAN signal time is used as the second unique information, and the transmitter position coordinates are used as the third unique information. And the position coordinates of the derived transmitter and the notification If the transmitter position coordinates calculated from the time of the received signal have a certain relationship, it is determined that the transmitter is in the correct position (illegal! /), And the service is used for regular use. I do.

[0094] [Example 3]

In the third embodiment of the present invention, as in the second embodiment, the wireless LAN signal time is used as the second unique information, and the position (coordinate) is used as the third unique information. ) Is different from Example 2.

[0095] The configuration of the present embodiment includes a wireless LAN base station as the wireless base station 1031, a transmitter 100;

The operation will be described with reference to FIG.

[0097] First, the position information (transmitter ID, etc.) and the times of a plurality of wireless LAN signals to which the notebook PC power S and infrared transmitter power are transmitted are acquired (step 4001). Here, the wireless LAN signal time includes the radio wave propagation time between each wireless LAN base station notebook PC, the round-trip radio wave propagation time between each wireless LAN base station notebook PC, and the signal from the notebook PC. At least one of the time when the signal arrives and the time when the signal from each wireless LAN base station reaches the notebook PC is used.

Next, the position (coordinates) is calculated using the time of the signal acquired by the notebook PC from the wireless LAN base station (step 4002). Here, in order to calculate the position using the time of the signal, the position of the wireless LAN base station is held in the notebook PC, and the commonly used trilateral survey such as GPS positioning or wireless LAN positioning is performed. I will do it.

[0099] Then, the notebook PC notifies the server 1042 of the position information (transmitter ID, etc.) received from the infrared transmitter and the calculated position (coordinates) through the wireless LAN network (step 4003).

[0100] Then, server 1042 stores an infrared transmitter to be transmitted from the correspondence table stored in storage unit 40 of server 1042 based on the notified location information (transmitter ID, etc.). The position (coordinates) is derived (step 4007).

[0101] In addition, the comparison determination unit 30 of the server 1042 calculates the calculated position (coordinate) and the derived position (seat Is determined whether the position information notified by whether or not it satisfies a certain relationship is legitimate (step 4004), and the position information is from an unauthorized infrared transmitter In the case of unauthorized use of the service (step 4005), if it is determined that the location information is from a legitimate infrared transmitter, the service is properly used (step 4006).

[0102] Here, as an example of means for determining whether or not the calculated position (coordinate) and the derived position (coordinate) satisfy a certain relationship, the calculated position (coordinate) and the derived position If the distance from (coordinates) is within a certain distance, it is determined that the position information is from a regular infrared transmitter, and if it is more than a certain distance, it is determined that the position information is from an unauthorized infrared transmitter. There is. In addition, the server 1042 holds a correspondence table in which the coordinate range information for each transmitter ID is described as the derived position (coordinates) as in the example of FIG. 8, and the calculated position (coordinates) is derived. The position information etc. is correct depending on whether it falls within the position (coordinates) range! /, The correct installation at the position! /, Or whether the information is from the transmitter! /, There are other ways.

[0103] Further, when the position information that can be acquired from the infrared transmitter is a coordinate, the means of deriving the position (coordinate) becomes unnecessary, and the position (coordinate) information itself acquired by the infrared transmitter force can be used. In this case, the server 1042 does not have to hold the table as shown in FIG.

[0104] Further, it is desirable that the time of the wireless LAN signal used is more reliable than the position information from the infrared transmitter.

In the present embodiment, the power mobile phone base station shown in the example using the wireless LAN base station as the radio base station may be used.

[0106] In addition, a wireless transmitter other than a wireless LAN base station used in power communication that shows an example using an infrared transmitter as a transmitter (for example, a wireless LAN transmitter, a zigbee transmitter, a specific power-saving wireless transmitter) , RFID transmitter, visible light transmitter, UWB transmitter, mobile phone radio transmitter).

[0107] Note that, when using signals from other wireless transmitters, a wireless interface that can be received by the wireless transmitter used in the mopile terminal needs to be installed. [0108] In addition, information associated with a position other than the position information from the transmitter, that is, the power using the time of the wireless LAN signal as the second specific information, the time of the signal of the mobile phone, the GPS satellite It may be signal time. When using GPS satellite signals, the mopile terminal must have a GPS interface!

[0109] In addition, a power PDA, a business dedicated terminal, a mobile phone, or the like showing an example using a notebook PC as a mopile terminal may be used.

[0110] Further, the latitude / longitude of the force in which the position (coordinates) was notified from the notebook PC to the server may be used.

[0111] As described above, the third embodiment is the same as the second embodiment in that the time of the wireless LAN signal is used as the second specific information and the position coordinate of the transmitter is used as the third specific information. The difference from the second embodiment is that the notebook PC (terminal) performs the process of calculating the position coordinates from the wireless LAN signal time, which is the second unique information. Therefore, the block diagram of the server in the third embodiment is obtained by deleting the second unique information conversion unit from FIG.

[0112] [Example 4]

In Example 4 of the present invention, an example will be described in which a photograph is used as the second unique information and a feature is used as the third unique information.

[0113] The configuration of the present embodiment is such that a mobile phone base station is used as the radio base station 1031, a transmitter 100;

Consider an infrared transmitter as 003, a mobile phone with a built-in infrared interface and camera as a mopile terminal;

[0114] The operation will be described with reference to FIG.

[0115] First, a photograph of a feature object whose position can be specified is taken with a mobile phone camera. Also receives location information periodically sent from the infrared transmitter (step 5001)

Yes

[0116] Here, features that can be identified include mountains such as Mt. Fuji, lakes, rivers, buildings, bridges, roads, road signs, and telephone poles. Then, the received location information and photograph are notified to the server 1042 using the cellular phone network (step 5002). The second unique information conversion unit 50 of the server 1042 extracts a feature whose position can be specified from the notified photograph (step 5003).

[0117] Here, as a means for extracting a feature whose photographic power can be specified, a general image It is conceivable to use pattern matching or the like. Then, the third unique information deriving unit 20 of the server 1042 installs an infrared transmitter to be transmitted from the correspondence table stored in the storage unit 40 of the server 1042 based on the notified position information! The feature that can be photographed at the position to be photographed is derived (step 5007).

[0118] After that, the comparison / determination unit 30 of the server 1042 determines whether the notified position information is valid based on whether the feature extracted from the photograph matches the feature derived from the position information. (Step 5004), and if it is determined that the location information is from an unauthorized infrared transmitter, the unauthorized use of the service is processed (step 5005), and the location information from a legitimate infrared transmitter is used. If it is determined that there is, the service is used for regular use (step 5006).

[0119] In the present embodiment, power wireless radio AN base stations may be used in which an example using a mobile phone base station as a radio base station is shown.

[0120] Although an example using an infrared transmitter as a transmitter has been shown, a wireless transmitter other than a mobile phone radio used in communication (for example, a wireless LAN transmitter, a zigbee transmitter, a specific power-saving radio) Transmitter, RFID transmitter, visible light transmitter, UWB transmitter, radio wave transmitter for mobile phone).

[0121] When using signals from other radio transmitters, a radio interface that can be received by the radio transmitter used in the mopile terminal needs to be installed.

[0122] Although an example using a mobile phone as a mopile terminal has been shown, a notebook PC, a PDA, a business dedicated terminal, a digital camera or the like may be used.

[0123] In this embodiment, a force photograph describing an example in which a feature is used as the third unique information may be used. When a photograph is used as the third unique information, the step (step 5003) of extracting a feature whose position can be specified by the notified photograph power in FIG. 11 can be omitted. In this case, the comparison / determination unit 30 compares the photographs.

[0124] At this time, it is assumed that the correspondence table stored in the server 1042 holds a photograph. In order to determine the authenticity of whether the notified location information is the information from the correct transmitter installed at the correct location, general pattern matching between the notified photo and the derived photo, etc. Can be considered. [0125] As described above, in Example 4, a photograph is used for the second unique information, and a feature is used for the third unique information. When the derived feature that can identify the transmitter location matches the feature that can identify the location of the transmitter extracted from the notified photo, the transmitter is in the proper position ( It is determined that it is not fraudulent!

[Example 5]

In the fifth embodiment of the present invention, an example will be described in which time is used as the second unique information and the business hours of the store are used as the third unique information.

[0127] Here, when a store is considered as a service providing place as an example of this time, the operating time may be limited depending on the store, and a situation in which the user cannot be in the store depending on the time occurs. In this example, information on a place that cannot be accessed is linked to this time.

[0131] Then, the received location information and time are notified to server 1042 using the cellular phone network (step 6002). After that, the third unique information deriving unit 20 of the server 1042 is based on the notified location information, and stores from the corresponding table stored in the storage unit 40 of the server 1042. The business hours are derived (Step 6005).

[0132] After that, the comparison / determination unit 30 of the server 1042 notifies whether or not the notified time and the derived business hours have a certain relationship, and whether or not the notified time is within the derived business hours. It is determined whether the received location information is legitimate (step 6003), and if it is determined that the location information is from an unauthorized infrared transmitter, processing for unauthorized use of the service is performed (scheduled) (Step 6004) If it is determined that the position information is from a regular infrared transmitter, the service is used for regular use (step 6005).

When the mopile terminals 1011 to 1013 enter the reception areas 1021 to 1023, the location information from the transmitters is received. It becomes possible to receive.

Here, as a method for obtaining the BSSID of the wireless LAN base station to which the notebook PC to which the server 1042 has notified the location information is connected, the management information stored in the wireless LAN base station is generally used. There are a method of judging from Base (MIB) information and a method of judging from MIB information stored in a notebook PC.

Judge whether the location information is legitimate (step 7004), and if it is judged that the location information is incorrect infrared transmitter power, process unauthorized use of the service (step 7005). If it is determined that the location information is from an infrared transmitter, the service is properly used (step 7006).

One way to improve reliability is to do so. In the above embodiment, the BSSID of the wireless LAN base station connected as the second unique information and the third unique information is used as an example using the BSSID of the wireless LAN base station connected. You can also use a combination or a combination of signal strengths from wireless LAN base stations that can be connected to a laptop.

[0159] Note that when using signals from other wireless transmitters, a wireless interface that can be received by the wireless transmitter used in the mopile terminal needs to be installed.

[0160] In addition, a power PDA, a business dedicated terminal, a mobile phone, or the like, which shows an example using a notebook PC as a mopile terminal, may be used.

[0161] As described above, in Example 6, the BSSID of the wireless LAN base station is used for both the second unique information and the third unique information. When the derived BSSID and the acquired BSSID satisfy a certain relationship (same), it is determined that the transmitter is in a regular position (no fraud), and processing for regular use of the service is performed.
