  As described above, according to the present invention, it is possible to provide an information transmission system that transmits a message associated with location information of a mobile phone to specific information having information about a location.

  Hereinafter, the present embodiment will be described with reference to the drawings. The information transmission system 1 in this embodiment includes a radio access network (RAN) 10, a core network (CN) 30, a source transmission unit 40, a message generation unit 50, and first to third databases 51. To 53 and first to fifth mobile phones 201 to 205 (see FIG. 1).

  The radio access network 10 includes first to twelfth base stations (BTS: Base Transceiver Stations) 101 to 112 that form a radio link facing a mobile phone. The core network 30 is a gateway mobile switching center (GMSC) 31 for connection to a telephone network such as another communication carrier, and an HLR (database that manages user information such as a mobile phone number and a terminal identification number). Home Location Register (33), a message service storage device (MPS) that holds SMS messages (first and second SMS messages) created for SMS (Short Message Service) until the receiving mobile phone is ready to receive. Message Processing System) 35 and first to fourth mobile switching centers (MSCs) 36 to 39 for performing routing (selection of communication route), call setting / disconnection, billing, and the like. The number of mobile phones and mobile exchanges is not limited to the above.

  The first to fifth mobile phones 201 to 205 can communicate with each other using a radio access network 10 and a core network 30 such as a call used for a normal mobile phone. This communication includes communication (call) with another communication carrier or a landline telephone via the gateway switch 31.

  For example, communication between the first mobile phone 201 and the second mobile phone 202 is performed via the second base station 102, the first mobile switch 36, the gateway switch 31, the second mobile switch 37, and the fourth base station 104. (Call) is enabled. Further, when they are in the same mobile switch area, communication is possible without using the gateway switch 31. For example, the second mobile phone 202 and the third mobile phone 203 in the same area of the second mobile switch 37 communicate with each other via the fourth base station 104, the second mobile switch 37, and the sixth base station 106. Is possible.

  Further, in addition to normal communication, in this embodiment, using the message generation unit 50 or the like, the location information of a mobile phone different from the transmission target mobile phone is added to the specific information output from the information source transmission unit 40. The transmitted first SMS message is transmitted to the mobile phones (first to fifth mobile phones 201 to 205) to be transmitted. In addition, in the second SMS message in which the location information of the mobile phone to be transmitted is added to the specific information, the mobile phone corresponding to the location information related to the location of the specific information (among the first to fifth mobile phones 201 to 205, Transmission to a mobile phone corresponding to this condition is performed.

  That is, the first SMS message is not related to the location of the specific information and is transmitted to the first to fifth mobile phones 201 to 205, and the second SMS message is only the mobile phone corresponding to the location information related to the location of the specific information. (In the specific example described later, it is transmitted only to the fifth mobile phone 205). The first SMS message includes location information of a mobile phone that is different from the mobile phone to be transmitted, and the second SMS message includes location information of the mobile phone to be transmitted.

  The first to third base stations 101 to 103 are connected to the first mobile switch 36. The fourth to sixth base stations 104 to 106 are connected to the second mobile exchange 37. The seventh to ninth base stations 107 to 109 are connected to the third mobile switch 38. The tenth to twelfth base stations 110 to 112 are connected to the fourth mobile switch 39. The first to fourth mobile exchanges 36 to 39, the HLR 33, and the message service storage device 35 are connected to the gateway exchange 31.

  The HLR 33 acquires location information of the first to fifth mobile phones 201 to 205 from a VLR (Visitor Location Register, not shown) which is a location registration database for each area covered by each of the first to fourth mobile exchanges 36 to 39. To do. When location registration communication (communication always performed between the mobile phone and the base station to inform the core network 30 of which base station the mobile phone is in) is executed in order to acquire location information, the VLR And the location information for each mobile phone of the HLR 33 is updated. The HLR 33 is used for specifying the location of a mobile phone that receives (calls) a call during normal communication. In addition, the HLR 33 is used to create the first database 51 in this embodiment.

  The information source transmission unit 40 outputs the specific information to the message generation unit 50. The specific information includes at least information related to the location. In the present embodiment, the specific information is described as disaster information such as an earthquake, but may be other information. Moreover, not only information that occurred in the past, such as an earthquake occurrence report, but information that is predicted to occur in the future, such as earthquake prediction, may be used. The specific information includes information on the type, location, and date / time of the disaster. In the present embodiment, it is assumed that the specific information has disaster type: earthquake / seismic intensity 3 / tsunami possibility, location: Takamatsu City, Kagawa Prefecture, date and time: December 2, 2007, 10:30. To do. The information source transmission unit 40 is installed in a location where disaster information can be transmitted, such as the Japan Meteorological Agency, in a state where the network connection with the message generation unit 50 is possible. However, the information source transmission unit 40 may not be installed, and disaster information may be received to input specific information to the message generation unit 50.

  The message generation unit 50 configured by a personal computer or a workstation is connected to the gateway switch 31, the message service storage device 35, the first to third databases 51 to 53, and the information source transmission unit 40. The message generation unit 50 creates the first to third databases 51 to 53 based on the information of the HLR 33 and the like, and stores the specific information output from the information source transmission unit 40 and the first to third databases 51 to 53. Based on this, software is installed that performs control for creating the first and second SMS messages for each mobile phone to be transmitted and outputting them to the message service storage device 35. The message storage device 35 stores the first and second SMS messages until the mobile phone that receives the first and second SMS messages is ready to receive. The first and second SMS messages are transmitted to the mobile phone to be transmitted.

  The first database 51 is a database of position information of the first to fifth mobile phones 201 to 205 utilizing the information transmission system 1 in the present embodiment, and the first database 51 is created based on the information of the HLR 33 and the like. The

  The first database 51 has a mobile phone name, a telephone number, position information (latitude and longitude information), positioning date and time (time information), and positioning accuracy (see FIG. 2). The message generation unit 50 acquires the position information of the first to fifth mobile phones 201 to 205 from the HLR 33 in order to create the first database 51. However, the position information recorded in the HLR 33 is based on cell-based positioning calculated based on radio wave information from a single base station, and has an error of 100 to 10000 meters. For this reason, in the present embodiment, the message generator 50 includes the first to fifth mobile phones 201 via the gateway switch 31, the first to fourth mobile switches 36 to 39, and the first to twelfth base stations 101 to 112. ˜205 to obtain more accurate position information.

  Specifically, when the mobile phone has a GPS (Global Positioning System) function and GPS positioning is possible, the mobile phone acquires latitude and longitude information by GPS positioning and does not have a GPS function or GPS When positioning is not possible, latitude / longitude information is acquired by positioning at a plurality of base stations that calculate positions based on radio wave information from three or more base stations. In the case of GPS positioning, the error can be reduced to about 10 meters, and in the case of multiple base station positioning, the error can be reduced to about 100 meters. Latitude / longitude information obtained by GPS positioning or multiple base station positioning may be transmitted superimposed on radio waves used in normal position registration communication, or may be transmitted separately using other data communication.

  FIG. 2 shows latitude and longitude information of the first to fifth mobile phones 201 to 205 as a specific example of the first database 51. When communication with the mobile phone cannot be performed, such as when the power is turned off, the positioning date and time may become old (early time) (see the positioning date and time of the fourth mobile phone 204 in FIG. 2).

  The positioning accuracy represents a value that varies depending on the positioning method, and is used to determine the display range of the area name described later. In this embodiment, the value is set to 1 in the case of GPS positioning with the highest positioning accuracy, the value is set to 2 in the case of multiple base station positioning with the next highest positioning accuracy, and the value is set in the case of cell-based positioning. Set to 3.

  The creation of the first database 51 may be based on another location information database that the communication carrier has.

  The second database 52 is a table for converting latitude / longitude information into area names, and has latitude / longitude information and area names corresponding to the latitude / longitude information (see FIG. 3). The second database 52 converts the latitude / longitude information of the first to fifth mobile phones 201-205 included in the first database 51 into an area name corresponding to the closest latitude / longitude information included in the second database 52. Used to do. In the present embodiment, a form in which a name such as a municipality or a lot number is used as the area name will be described. However, a form using a facility name such as “Tokyo Disneyland” may be used.

  For example, the latitude of the first mobile phone 201 included in the first database 51: 35.657102 degrees and longitude: 139.7745820 degrees correspond to the area name included in the second database 52: Shiba Park 4 in Minato-ku, Tokyo. Since it is closest to latitude: 35.657143 degrees and longitude: 139.774572 degrees, it is calculated that the second mobile phone 201 is in the vicinity of Shiba Park 4 in Minato-ku, Tokyo, and the use of the second mobile phone 201 is used. It is estimated that the person is in the area name: Shiba Park 4 near Minato-ku, Tokyo.

  The area name calculated in this way is included in first and second SMS messages described later. However, the range to be displayed as the area name (the degree of detail of the area name described in the first and second SMS messages) is changed according to the positioning accuracy value. Specifically, when the accuracy of the positioning method for acquiring latitude / longitude information is high, the area name including the detailed place name is displayed, and when the accuracy is low, the area name up to a rough place name is displayed. In the present embodiment, in the case of GPS positioning, that is, when the value of positioning accuracy is 1, the area name including the block name and the lot number of the municipality, etc .: Shiba Park 4 in Minato-ku, Tokyo is displayed. If the positioning accuracy value is 2, display the area name including the municipality, etc .: Shiba Park, Minato-ku, Tokyo, and in the case of cell-based positioning, that is, when the positioning accuracy value is 3. Local name including city name or ward name: Minato-ku, Tokyo is displayed. Note that the display range of the area name is not limited to this, and is preferably set according to the positioning accuracy.

  The third database 53 has a mobile phone name to be transmitted and a mobile phone name corresponding to the location information included in the first SMS message. The mobile phone name corresponding to the location information included in the first SMS message is arbitrarily set by the user or the like. In FIG. 4, as a specific example of the third database 53, the first mobile phone 201 includes the second mobile phone 202, the fourth mobile phone 204, and the fifth mobile phone 205 together with the specific information from the information source transmission unit 40. The location information (area name) is sent, and the location information of the first mobile phone 201 and the fifth mobile phone 205 is sent to the second mobile phone 202 together with the specific information from the information source transmission unit 40, and is sent to the third mobile phone 203. Sends the positional information of the first mobile phone 201 and the fifth mobile phone 205 together with the specific information from the information source transmitting unit 40, and the first mobile phone together with the specific information from the information source transmitting unit 40 is sent to the fourth mobile phone 204. The location information of the telephone 201 and the third mobile phone 203 is sent, and the content that the location information of the second mobile phone 202 is sent to the fifth mobile phone 205 together with the specific information from the information source transmitter 40 is shown. In the third database 53, a corresponding mobile phone number may be used instead of the mobile phone name. The mobile phone name corresponding to the location information included in the first SMS message may include the mobile phone name to be transmitted.

  When the mobile phone names corresponding to the location information included in the first SMS message are the same, the first SMS message having the same content is created. For example, since the mobile phone name corresponding to the location information included in the first SMS message is the same, the content of the first SMS message to the second mobile phone 202 is the same as the content of the first SMS message to the third mobile phone 203 become. In this case, since the message generation process can be simplified rather than creating the first SMS message having different contents, the processing speed is improved.

  If there are many transmission targets, the time for creating the first SMS message may be long, that is, the processing speed of the message generation process may be slow. In this case, a plurality of transmission target mobile phones are grouped, and the mobile phone names corresponding to the location information included in the first SMS message are set to the same for the transmission target mobile phones included in the same group. The first SMS message having the same content is created in the mobile phone to be transmitted. As a result, the mobile phone name corresponding to the location information included in the first SMS message may include the mobile phone name to be transmitted, but the message generation process can be simplified and the processing speed can be improved. Become.

  GPS positioning and multiple base station positioning are performed at regular intervals, for example, every time position registration communication is performed, and the first database 51 is updated in response to the update of the HLR 33 by such communication. The second database 52 is a database (conversion table) created in advance. The third database 53 is set in advance by accessing the message generator 50 from a mobile phone or a personal computer (not shown).

  When the specific information is received from the information source transmitting unit 40, the message creating unit 50 creates the first SMS message for each mobile phone to be transmitted based on the specific information and the first to third databases 51 to 53, and stores the message service. Output to the device 35. Specifically, the message creation unit 50 converts the latitude / longitude information of the first to fifth mobile phones 201 to 205 included in the first database 51 into an area name using the second database 52, and As the location information, it is used for the first SMS message. The mobile phone name that needs to be transmitted to the mobile phone to be transmitted is specified based on the third database 53.

  Based on these, in addition to displaying the specific information, the message creating unit 50 creates a first SMS message that displays the location information of the mobile phone that needs to be transmitted to the mobile phone to be transmitted. The first half of the first SMS message (specific information display orchid) shows the type of disaster: earthquake, seismic intensity 3, tsunami, location: Takamatsu City, Kagawa Prefecture, and date: 10:30 on December 2, 2007 Including the message “There was an earthquake with a seismic intensity of 3 at 10:30 on December 2, 2007 in Takamatsu City, Kagawa Prefecture.” In the latter half part (position information display column), when transmitting to the first mobile phone 201, the message “the second mobile phone is 10: 8” having the location information of the mobile phone that needs to be transmitted to the target mobile phone. Currently in Urayasu City, Chiba Prefecture.The fourth mobile phone is currently located in Ninomaru-cho, Shimizu-ku, Shizuoka-shi, Shizuoka Prefecture.The fifth mobile phone is currently 1st Uenocho, Takamatsu-shi, Kagawa Prefecture at 10:15 It has. " The display range (degree of detail) of the area name displayed in the position information display field is adjusted according to the positioning accuracy.

  The first SMS message is created by adding information such as a location related to specific information and location information of a mobile phone that needs to be transmitted to a mobile phone to be transmitted, to a predetermined position of a fixed phrase. FIG. 6 shows that the underlined character is a fixed sentence area, the bold part is an information area related to specific information, and the bold italic part is a position information area of a mobile phone that needs to be transmitted to a mobile phone to be transmitted. For this reason, after receiving specific information from the information source transmission part 40, it becomes possible to produce a lot of messages in a short time.

  Thereby, in addition to the specific information having the location information, the location information of another mobile phone, that is, the location information of the user of the other mobile phone can be sent to the mobile phone to be transmitted. The user of the mobile phone can confirm the content of the specific information by looking at the first SMS message, and also the relationship between the location of the user of the other mobile phone and the specific information, that is, the location related to the specific information such as a disaster. It is possible to check whether or not the user is in the vicinity.

  Further, when receiving the specific information from the information source transmitting unit 40, the message creating unit 50 creates a second SMS message for each mobile phone to be transmitted based on the specific information and the first and second databases 51 and 52. The data is output to the service storage device 35. Specifically, the message creation unit 50 uses the second database 52 for the latitude and longitude information of the first to fifth mobile phones 201 to 205 included in the first database 51 in order to identify the mobile phone to be transmitted. Then, it is converted into an area name, and this is used as position information to determine whether it is related to the location of the specific information. For example, when the location information of the mobile phone includes a part or all of the location of the specific information, it is determined that the location information of the mobile phone and the location of the specific information are related. In the present embodiment, the location information of the fifth mobile phone 205: the location information of the fifth mobile phone 205 is the location of the specific information because the location information of the fifth mobile phone 205: Uenomachi 1 in Takamatsu City, Kagawa Prefecture includes the location of the specific information: Takamatsu City, Kagawa Prefecture And is set as a transmission target of the first SMS message. Since the location information of the first to fourth mobile phones 201 to 204 does not include the location of the specific information: Takamatsu City, Kagawa Prefecture, it is determined not to be related to the location of the specific information, and is excluded from the transmission target of the second SMS message. .

  Next, the message creation unit 50 creates a second SMS message that displays the location information of the mobile phone to be transmitted in addition to the display of the specific information. The first half of the second SMS message (specific information display orchid) shows the type of disaster: earthquake, seismic intensity 3, tsunami, location: Takamatsu City, Kagawa Prefecture, and date: 10:30 on December 2, 2007 Including the message “In Takamatsu City, Kagawa Prefecture, there was an tsunami with a seismic intensity of 3 at around 10:30 on December 2, 2007.” The second half (position information display field) is a message having the position information of the mobile phone to be transmitted (here, the fifth mobile phone 205) "5th mobile phone, that is, this mobile phone is at 10:15, as of Kagawa prefecture. It is in Uenomachi, Takamatsu City. The display range (degree of detail) of the area name displayed in the position information display field is adjusted according to the positioning accuracy.

  The second SMS message is created by adding information such as a location related to the specific information and position information of the mobile phone to be transmitted to a predetermined position of the fixed phrase. FIG. 7 shows that the underlined character is a fixed sentence area, the bold part is an information area related to specific information, and the bold italic part is a position information area of a mobile phone to be transmitted. For this reason, after receiving specific information from the information source transmission part 40, it becomes possible to produce a lot of messages in a short time.

  Thereby, in addition to the specific information having the location information, the location information of the mobile phone that is the transmission target and receives the second SMS message, that is, the second SMS message that is the transmission target and receives the second SMS message. It becomes possible to send the location information of the user of the mobile phone. The user of the mobile phone can check the content of the specific information by looking at the second SMS message, and can also check the relationship between the position of the mobile phone to be used and the specific information, that is, the location near the specific information such as a disaster. It becomes possible to confirm whether or not there is.

  In this embodiment, since SMS (first and second SMS messages) is used as a message transmission means, E-mail for transmitting a message via the mail server 60 using SMTP (Simple Mail Transfer Protocol) or the like is used. Compared to the mode of use (see FIG. 8), transmission can be completed quickly and reliably. In particular, in the event of a disaster that is included in the specific information, there is a risk that communication will be congested and it will be difficult to connect, and there will be a significant delay. In SMS that sends the first and second SMS messages to the mobile phone number, Such problems are unlikely to occur.

  However, the message transmission means may use an E-mail that transmits a message via the mail server 60. In this case, instead of outputting the first and second SMS messages to the message storage device 35, the message generator 50 sends the contents of the first and second SMS messages to the mail server 60 of the Internet provider or communication carrier. E-mail including

  In the form of using E-mail via the mail server 60, if it has an E-mail address, it can be used for other message receiving means other than a mobile phone such as a computer (eg, the first personal computer 211) or a PDA. It becomes possible to send a message. In this case, since it is not a telephone number but an E-mail address that is required as a destination address, it is necessary to prepare information on the E-mail address for each receiving means such as a mobile phone in the first database 51 or the like ( (See FIG. 9). In addition, it is necessary to prepare in the third database 53 and the like the name of a receiving means such as a mobile phone to be transmitted and the name of the mobile phone corresponding to the location information included in the first SMS message (see FIG. 10).

  However, since the latitude / longitude information of the message receiving means other than the mobile phone is not recorded in the first database 51, the E-mail including the content of the second SMS message is not transmitted to the other message receiving means.

  In addition, in this embodiment, in order to improve the positioning accuracy of position information, a mode in which GPS positioning or multiple base station positioning is performed in addition to cell-based positioning normally performed between a mobile phone and a base station has been described. However, since approximate position information can be obtained by cell-based positioning, a form that does not use GPS positioning or the like may be used. In this case, the system (software) can be simplified to the extent that the message generator 50 does not need to control the gateway switch 31 or the like for GPS positioning or the like.
