Description

  The present invention relates to a distribution information transmission / reception system, a distribution system, a terminal, and a distribution information transmission / reception method related to distribution of distribution information.

  Conventionally, distribution information related to the occurrence of disasters such as earthquake warnings and various alarms is distributed to terminals. In the following Patent Document 1, it is proposed to use position information indicating the position of the terminal in order to appropriately output such information to the user. Patent Document 1 describes the following system.

  In this system, a broadcasting station multiplexes a plurality of disaster information together with position information (specifically, latitude and longitude) and distributes the data as a data broadcast. The receiving terminal receives the data broadcast and separates it into individual disaster information. The receiving terminal acquires position information by GPS or the like, extracts disaster information based on the position information about the separated disaster information and the acquired position information, accumulates and displays the information. For example, the disaster information corresponding to the position information within a predetermined range is extracted from the position information acquired by GPS or the like as the position information of the disaster information. As a result, the disaster information sent unilaterally by the broadcasting station is automatically selected based on the location information of the receiving terminal, stored and displayed, and thus the user needs the disaster information to be referred to by the user. It is said that there is a high possibility.

  Hereinafter, embodiments of a distribution information transmission / reception system, a distribution system, a terminal, and a distribution information transmission / reception method according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 shows a distribution information transmission / reception system 1 according to the present embodiment. The distribution information transmission / reception system 1 includes a terminal 10 and a distribution system 20. The distribution information transmission / reception system 1 is a system in which the distribution system 20 distributes distribution information to the terminal 10 and the terminal 10 receives and outputs the distribution information. The distribution information is evacuation site information indicating an evacuation site when a disaster such as an earthquake occurs, for example. Information other than the evacuation site information is also distributed as distribution information. Distribution of distribution information is performed via the mobile communication network N. Distribution of distribution information is performed by broadcast distribution (broadcast) to the terminals 10 located in the mobile communication network N so that the terminals 10 can receive all at once. The mobile communication network N is a communication network that provides the terminal 10 with a mobile communication function.

  The terminal 10 is a device that is used by a user and connected to the mobile communication network N by wireless communication to perform mobile communication. That is, the terminal 10 has a mobile communication function by the mobile communication network N. Specifically, the terminal 10 corresponds to a mobile phone or the like. The terminal 10 receives and outputs distribution information from the distribution system 20 via the mobile communication network N. For example, the terminal 10 displays distribution information. The user grasps the contents of the distribution information by referring to the displayed distribution information. For example, when the distribution information is evacuation location information, the user can grasp where to evacuate.

  The distribution system 20 is a system that distributes distribution information to the terminal 10. The distribution system 20 includes a xGSN (serving / gateway general packet radio service (GPRS) Support Node) 30 and an RNC (Radio Network Controller) 40. The distribution system 20 is included in the mobile communication network N. The xGSN 30 and the RNC 40 are the same as the xGSN and RNC included in the conventional mobile communication network, except that the xGSN 30 and the RNC 40 have a function according to this embodiment described later. The xGSN 30 includes a SGSN (Serving GPRS Support Node). The mobile communication network N includes a plurality of xGSNs 30 for each communication area. The xGSN 30 is connected to one or more RNCs 40 for each communication area in which the communication area of the xGSN 30 is subdivided. The xGSN 30 stores the address of the connected RNC 40 in advance. Note that a communication area of each RNC 40 usually includes a plurality of sectors. Each sector area may include multiple evacuation sites. The terminal 10 is located under the RNC 40 and the xGSN 30 corresponding to the position of the terminal 10 and performs mobile communication. The xGSN 30 acquires evacuation site information that is distribution information, and outputs the acquired evacuation site information to the RNC 40. The RNC 40 transmits the evacuation site information to the terminal 10.

  The mobile communication network N includes a CBC (Cell Broadcast Center) 50 and a position information positioning device 60 as devices according to the present embodiment. Although not shown, the mobile communication network N includes devices (nodes) included in the conventional mobile communication network in addition to the above, and functions in the same manner as the conventional mobile communication network. For example, a base station that transmits and receives radio signals to and from the terminal 10 is provided under the RNC 40. Further, a CBE (Cell Broadcast Entity) 70 is connected to the CBC 50 so that information can be transmitted and received.

  The CBE 70 is arranged in the local government or the Japan Meteorological Agency, etc., and when a disaster such as an earthquake occurs or when a disaster is predicted, a message (for example, an emergency earthquake warning message) relating to the disaster is sent to the CBC 50. It is a device that transmits. The CBE 70 is a device similar to a conventional CBE. A region is set in the message transmitted from the CBE 70. The region is, for example, a region where a disaster indicated by a message has occurred or a disaster is predicted to occur. The region is, for example, a municipal unit. Specifically, the electronic message is associated with information indicating the area to which the electronic message is to be distributed (for example, a prefectural area code that specifies the area to be distributed within the prefecture).

  The CBC 50 is a device that receives a telegram related to a disaster from the CBE 70 and transmits the telegram as distribution information. The CBC 50 stores in advance information for specifying the xGSN 30 that can distribute the distribution information to the area from the information indicating the area associated with the electronic message. Based on the information stored in advance, the CBC 50 specifies the xGSN 30 from the information indicating the area associated with the message received from the CBE 70, and transmits the distribution information to the specified xGSN 30. The CBC 50 is a device similar to a conventional CBE.

  The position information positioning device 60 is a device that performs positioning of the terminal 10 in response to a positioning request from the terminal 10. For example, when receiving the positioning request from the terminal 10, the position information positioning device 60 specifies the latitude and longitude as the position of the terminal 10 and transmits information indicating the latitude and longitude to the terminal 10. The position information positioning device 60 is specifically an ALS (Adjacency-based Location System).

  Subsequently, functions according to the present embodiment will be described. The xGSN 30 includes a distribution information acquisition unit 31. Note that the xGSN 30 has a function provided by the conventional xGSN in addition to the above-described function unit.

  The distribution information acquisition unit 31 is a distribution information acquisition unit that acquires distribution information that is distributed to the terminal 10 and includes information indicating a position. The distribution information acquisition unit 31 stores a plurality of evacuation site information in advance, and acquires the stored evacuation site information as distribution information. One evacuation site information is information indicating one evacuation site. The evacuation site information is input to the xGSN 30 in advance by a communication carrier of the mobile communication network N or the like. The distribution information acquisition unit 31 stores in advance and acquires evacuation site information for all evacuation sites included in a communication area (distribution area) where information can be transmitted from the xGSN 30.

  The evacuation site information is, for example, information shown in the table of FIG. One row in the table of FIG. 2 corresponds to one evacuation site information. As shown in the table of FIG. 2, the evacuation site information is information in which evacuation site, position, number of persons accommodated, remarks, gender and age information are associated with each other. The evacuation site is information indicating the name of the evacuation site related to the evacuation site information. The position is information indicating the position of the evacuation site according to the evacuation site information. The position is information indicating the latitude and longitude of the evacuation site, for example. In addition to the information indicating the latitude and longitude, for example, the location information of the evacuation site such as “Kanagawa Ward xxx in Yokohama City” may be included as the location information. The capacity is the number of people that can be accommodated in the evacuation site. The remarks are information that the user should know about the evacuation site. The sex type is information indicating the sex of the evacuees who can be accommodated in the evacuation area. The age is information indicating the age of the evacuees that can be accommodated in the evacuation site, and is indicated in the age range. In the present embodiment, the remarks, gender and age information are not necessarily required. However, each gender and age information is required in a modification described below.

  The distribution information acquisition unit 31 receives distribution information related to a disaster transmitted from the CBC 50 to the own device 30. When receiving the distribution information from the CBC 50, the distribution information acquisition unit 31 acquires all the stored evacuation site information. The distribution information acquisition unit 31 adds the acquired evacuation site information to the distribution information received from the CBC 50 and transmits it to all the RNCs 40 connected to the own device 30 (all the RNCs 40 subordinate to the own device 30). The distribution information acquisition unit 31 may transmit the acquired evacuation site information to the RNC 40 as distribution information separately from the distribution information received from the CBC 50. Further, the distribution information acquisition unit 31 may further add information indicating that the evacuation site information is included in the distribution information including the evacuation site information. The above is the functional configuration of the xGSN 30.

  The RNC 40 includes a number-of-zones information acquisition unit 41 and a transmission unit 42. The RNC 40 has a function provided in the conventional RNC, in addition to the above-described functional unit.

  The in-zone number information acquisition unit 41 is in-zone number information acquisition means for acquiring in-zone number information indicating the number of in-zone users, which is the number of terminals 10 in a predetermined area in the mobile communication network N. is there. The RNC 40 normally knows the number of users in the area under its own device 40 (communication area of the own device 40). The in-zone number information acquisition unit 41 receives the distribution information including the evacuation place information transmitted from the xGSN 30 to the own device 40. When receiving the distribution information including the evacuation site information, the number-of-zones information acquisition unit 41 detects the number of users in the area under control of the own device 40 (communication area of the own device 40) at that time, and The number information of the number of areas indicating the number is acquired. That is, the predetermined area is a communication area of the RNC 40. When the number-of-zones information acquisition unit 41 acquires the number-of-zones information, the location-number information acquisition unit 41 outputs the received distribution information and the acquired number-of-zones information to the transmission unit 42.

  The transmission unit 42 is a transmission unit that receives the distribution information and the number-of-services information from the service area information acquisition unit 41, associates the information, and transmits the information to the terminal 10 via the mobile communication network N. The transmission unit 42 transmits the information from all base stations under its own device 40 by broadcast distribution. The information is transmitted in a text format, for example. This is to allow all terminals 10 located under the own device 40 to receive the distribution information. Note that, as described above, since the xGSN 30 transmits the same distribution information to all of the subordinate RNCs 40, the terminal 10 located in the area constituting the communication area under the control of the xGSN 30 receives the same distribution information. The functional configuration of the RNC 40 has been described above.

  The terminal 10 includes a position information acquisition unit 11, a reception unit 12, an output determination unit 13, and an output unit 14. In addition to the above-described functional units, the terminal 10 may also have, for example, functions provided in a conventional mobile phone.

  The position information acquisition unit 11 is a position information acquisition unit that acquires position information indicating the position of the terminal 10 itself. For example, the location information acquisition unit 11 sends a positioning request for the terminal 10 to the location information positioning device 60 via the mobile communication network N. In response to the positioning request, the position information acquisition unit 11 receives information indicating the latitude and longitude that are the position of the terminal 10 as a positioning result by the position information positioning device 60. The position information acquisition unit 11 stores the acquired position information indicating the position of the terminal 10 together with the acquired time as a positioning history.

  The position information acquisition unit 11 receives a request for position information from the output determination unit 13 and outputs the position information to the output determination unit 13. When receiving the request, the position information acquisition unit 11 determines whether or not the elapsed time from the time related to the latest (most recent) position information stored at that time is within a predetermined time. . If the position information acquisition unit 11 determines that the elapsed time is within the time specified in advance, the position information acquisition unit 11 outputs the latest position information to the output determination unit 13. On the other hand, if the position information acquisition unit 11 determines that the elapsed time is not within the time specified in advance, the position information acquisition unit 11 newly acquires the position information of the own terminal 10 and outputs the acquired position information to the output determination unit 13. To do. The predesignated time is, for example, a time that the user cannot move greatly from the position indicated by the position information. However, when there is a request for position information from the output determination unit 13, the position information acquisition unit 11 may uniformly acquire new position information of the terminal 10 itself.

  Note that the acquisition of the position information by the position information acquisition unit 11 is not necessarily performed by the position information positioning device 60, and may be performed by other methods. For example, position information may be acquired (positioning) inside the terminal 10. Specifically, the position information of the own terminal 10 may be acquired by GPS (global positioning system). In this case, the position information acquisition unit 11 has a function of receiving a GPS signal and a function of performing a positioning calculation based on the received GPS signal. Further, the acquisition of the position information by the position information acquisition unit 11 may be performed using a request other than the request from the output determination unit 13 as a trigger. That is, the acquisition of the position information by the position information acquisition unit 11 may be performed by an arbitrary function using the position information of the terminal 10 other than the function of the present embodiment.

  The receiving unit 12 is a receiving unit that receives the evacuation site information and the number of located areas information that are associated with each other and transmitted (broadcasted) from the mobile communication network N. The receiving unit 12 outputs the received information to the output determining unit 13.

  The output determination unit 13 is an output determination unit that determines whether or not to output the evacuation site information received by the reception unit 12. The output determination unit 13 performs the above determination based on the positional relationship between the position of the evacuation site and the position of the terminal 10 indicated by the information included in the evacuation site information, and the number of in-zone information received by the reception unit 12. Do. Specifically, the output determination unit 13 performs the above determination as follows.

  The output determining unit 13 determines whether or not the information that is broadcast and received by the receiving unit 12 includes evacuation site information. This determination is performed, for example, by determining whether or not the distribution information includes information indicating that the evacuation site information (included by the xGSN 30) is included. When the output determination unit 13 determines that the information received by the reception unit 12 does not include the evacuation site information, the output determination unit 13 performs the process according to the received information without performing the process according to the present embodiment.

  When the output determination unit 13 determines that the information received by the reception unit 12 includes the evacuation site information, the output determination unit 13 requests the location information acquisition unit 11 for the location information of the terminal 10 and the location information acquisition unit 11 Enter location information. For each evacuation site information, the output determination unit 13 calculates the time required when walking from the location of the terminal 10 indicated by the input location information to the location of the evacuation site indicated by the information included in the evacuation site information. calculate. The calculation of the required time can be performed by the function of the conventional navigation software based on, for example, map data including those positions.

  The output determination unit 13 selects (determines) an evacuation site information as an output candidate from the calculated walking time. For example, evacuation site information whose required time is equal to or less than a preset threshold is set as an output candidate. For example, the threshold is set to a value that allows the user to evacuate without difficulty. As shown in FIG. 3, for example, three evacuation site information is set as output candidates. In FIG. 3, the evacuation site information is arranged in ascending order of the required time (see the required time column in FIG. 3).

  The output determination unit 13 compares the number of accommodated people indicated by the information included in the evacuation site information as the output candidate with the number of in-zone users indicated by the number-of-area information in order of decreasing required time. The output determination unit 13 first determines the evacuation site information to output the evacuation site information in which the number of accommodated persons is equal to or greater than the number of terminals 10 by the comparison. That is, the evacuation site information about the evacuation sites having the capacity equal to or more than the number of the terminals 10 is determined as the information to be output.

  For example, if the evacuation site information as output candidates is shown in FIG. 3 and the number of users in the area is 50,000, “evacuation site 6” having the shortest required time has a capacity of 10,000 people. Since it is smaller than 50,000, the information is not output. Next, “evacuation site 7”, which has the shortest required time, has a capacity of 60,000 and is larger than 50,000, and is therefore determined as information to be output as the evacuation site information relating to the optimum evacuation site (FIG. 3). (See the output judgment column).

  The output determination unit 13 outputs the evacuation site information determined to be output to the output unit 14. As described above, the evacuation site information includes information on the number of accommodated persons, which is a numerical value compared with the number of users in the area. In addition, the determination of the output candidate may be performed based on the straight line distance by calculating the straight line distance from the position of the terminal 10 to the evacuation place from the position instead of the required time. In the case of using a straight line distance as well, it is only necessary that the straight line distance be equal to or less than a preset threshold as an output candidate.

  The output unit 14 is an output unit that outputs evacuation site information (optimum evacuation site information) determined to be output by the output determination unit 13. This output is performed, for example, by displaying the evacuation site information on a display device such as a display provided in the terminal 10. Further, the route from the position of the terminal 10 to the evacuation site may be calculated and displayed. The calculation of the route can be performed by the function of the conventional navigation software based on the map data including those positions. The output does not necessarily have to be a display output, and any method can be adopted as long as it is a method that can be recognized by the user, such as voice output. The functional configuration of the terminal 10 has been described above.

  FIG. 4 shows a hardware configuration of the terminal 10 according to the present embodiment. As shown in FIG. 4, the terminal 10 includes a central processing unit (CPU) 101, a random access memory (RAM) 102 and a read only memory (ROM) 103 that are main storage devices, an operation module 104, a wireless communication module 105, and an antenna 106. The display 107 is configured by hardware. The functions of the terminal 10 described above are exhibited by the operation of these components by a program or the like.

  FIG. 5 shows a hardware configuration of the xGSN 30 and the RNC 40 according to the present embodiment. As shown in FIG. 5, the xGSN 30 and the RNC 40 are configured as a server device including a CPU 301, a RAM 302 and a ROM 303 as main storage devices, a communication module 304 for performing communication, and an auxiliary storage device 305 such as a hard disk. The The functions of the xGSN 30 and the RNC 40 described above are exhibited when these components are operated by a program or the like. The above is the configuration of the distribution information transmission / reception system 1 and the terminal 10 and the distribution system 20 included in the distribution information transmission / reception system 1 according to the present embodiment.

  Subsequently, using the sequence diagram of FIG. 6 and the flowchart of FIG. 7, distribution information transmission / reception that is a process executed by the distribution information transmission / reception system 1 (the respective operation methods of the distribution information transmission / reception system 1, distribution system 20, and terminal 10) A method, a distribution method, and an information output method will be described. First, the overall processing in the distribution information transmission / reception system 1 will be described using the sequence diagram of FIG. 6, and then the processing in the terminal 10 will be described using the flowchart of FIG.

  In this process, first, an emergency earthquake warning message, which is a message related to a disaster, is transmitted from the CBE 70 to the CBC 50 (S01). The electronic message is received by the CBC 50, and an acceptance response indicating that the electronic message has been accepted is transmitted from the CBC 50 to the CBE 70 (S02). In addition, the electronic message is transmitted from the CBC 50 to the xGSN 30 as distribution information (S03). In the xGSN 30, the distribution information acquisition unit 31 receives distribution information related to the disaster. Next, the evacuation site information is acquired by the distribution information acquisition unit 31 (S04, distribution information acquisition step). Subsequently, the distribution information acquisition unit 31 adds the acquired evacuation site information to the distribution information received from the CBC 50 and transmits it to all the RNCs 40 connected to the own device 30 (S05).

  The distribution information transmitted from the xGSN 30 to the RNC 40 is received by the in-zone number information acquisition unit 41. Subsequently, the number-of-zones information acquisition unit 41 acquires the number-of-zones information (S06, number-of-zones information acquisition step). The received distribution information and the acquired in-zone number information are output from the in-zone number information acquiring unit 41 to the transmitting unit 42. Subsequently, the transmission unit 42 associates the distribution information and the number-of-service areas information and transmits the information to the terminal 10 via the mobile communication network N (S07, transmission step).

  Subsequently, in the terminal 10 located under the RNC 40, the distribution information transmitted from the RNC 40 is received by the receiving unit 12. The received distribution information is output from the receiving unit 12 to the output determining unit 13. In the RNC 40, when the distribution information is transmitted, the transmission unit 42 transmits a distribution completion report indicating that the transmission of the distribution information is completed to the xGSN 30 (S08). The delivery completion report is transmitted to the CBE via the xGSN 30 and the CBC 50 (S09, S10).

  On the other hand, in the terminal 10, the positioning information acquisition unit 11 makes a positioning request for the terminal 10 to the positioning information positioning device 60 (S11, positioning information acquisition step). The position information positioning device 60 receives the positioning request and performs positioning of the terminal 10 (S12). The position information of the terminal 10 as a positioning result is transmitted from the position information positioning device 60 to the terminal 10. In the terminal 10, the position information acquisition unit 11 receives the position information (S13, position information acquisition step). The received position information is output from the position information acquisition unit 11 to the output determination unit 13. Subsequently, the output determination unit 13 determines which evacuation site information to be output among the evacuation site information included in the distribution information received by the reception unit 12 (S14, output determination step). The evacuation site information determined to be output is output from the output determination unit 13 to the output unit 14. Subsequently, the output unit 14 outputs the displayed evacuation site information and the like (S15, output step). The above is the overall processing in the distribution information transmission / reception system 1.

  Subsequently, the processing in the terminal 10 will be described in detail using the flowchart of FIG. In the terminal 10, the distribution information transmitted from the RNC 40 is received by the reception unit 12 (S21, reception step). The received distribution information is output from the receiving unit 12 to the output determining unit 13. When the distribution information is received, a response is transmitted from the receiving unit 12 to the RNC 40. Subsequently, the output determining unit 13 determines whether or not the distribution information received by the receiving unit 12 includes evacuation site information (whether or not the distribution information is evacuation site information) (S22). When it is determined that the distribution information does not include the evacuation site information (NO in S22), the process according to the present embodiment is not performed, and the process according to the received information is performed.

  When it is determined that the distribution information includes the evacuation site information (YES in S22), the output determination unit 13 requests the location information acquisition unit 11 for the location information of the terminal 10 itself. The position information acquisition unit 11 that has received the request determines whether or not a positioning history within a predetermined time is stored (S23). When such positioning history is stored (YES in S23), the position information of the positioning history is output from the position information acquisition unit 11 to the output determination unit 13. When such positioning history is not stored (NO in S23), the position information acquisition unit 11 newly acquires the position information of the own terminal 10 and outputs the acquired position information to the output determination unit 13. (S24).

  Subsequently, the output determination unit 13 to which the position information is input walks from the position of the terminal 10 indicated by the position information to the position of the evacuation place indicated by the information included in the evacuation place information for each evacuation place information. The required time when it is performed is calculated. Subsequently, the output determination unit 13 selects an output candidate among the evacuation site information from the calculated required time on foot (S25, output determination step).

  Subsequently, the output determining unit 13 determines the evacuation site information to be output from the evacuation site information as the output candidate based on the number-of-areas information received by the receiving unit 12 (S26, output determining step). The evacuation site information determined to be output is output from the output determination unit 13 to the output unit 14.

  Subsequently, the output unit 14 outputs the displayed evacuation site information and the like (S27, output step). In addition to the output of the evacuation site information itself, the output unit 14 calculates a route from the position of the terminal 10 to the evacuation site and outputs the route (S28, output step). The user of the terminal 10 can know which evacuation place should be evacuated at the time of a disaster by referring to the output. The above is the processing at the terminal 10.

  As described above, in the present embodiment, in addition to the positional relationship between the position of the evacuation site and the position of the terminal 10 indicated by the information included in the evacuation site information, the coverage area of the communication area of the RNC 40 in the mobile communication network N It is determined whether or not the evacuation site information is output at the terminal 10 based on the number-of-zones information indicating the number of users. The number of users in the area is usually according to the number of people located in the area. Therefore, in this embodiment, distribution information corresponding to the number of people located in the area is output from the terminal 10.

  Thereby, the information of the evacuation place in consideration of the accommodation number can be output. For example, it is possible to avoid a situation in which information on an evacuation area with a small number of accommodated persons is displayed on many terminals and an evacuee exceeding the accommodated number of persons evacuates to the evacuation area. In addition, this makes it possible to give the user peace of mind and safety. That is, according to this embodiment, appropriate distribution information can be output. In addition, since the system described in Patent Document 1 distributes information by data broadcasting from a broadcasting station, the number of users in the area cannot be grasped as in the present embodiment. Such delivery information output cannot be determined.

  Subsequently, a modification of this embodiment will be described. In this modification, the attribute of the user of the terminal 10 is used to determine whether to output the evacuation site information. For this purpose, the terminal 10 further includes an attribute information acquisition unit. The attribute information acquisition unit is attribute information acquisition means for acquiring attribute information indicating the attribute of the user of the terminal 10. User attributes include the user's gender and the user's age. The attribute information acquisition unit acquires, for example, by reading attribute information stored in advance in the terminal 10. Alternatively, the attribute information acquisition unit may acquire the attribute information by accepting an input operation of the attribute information from the user when the output of the evacuation site information is determined. The attribute information acquisition unit outputs the input attribute information to the output determination unit 13.

  The output determination unit 13 determines whether or not to output the evacuation site information based on the attribute information. The output determination unit 13 determines whether or not the attribute indicated by the attribute information satisfies the condition included in the evacuation site information in addition to the determination in the embodiment described above. The conditions included in the evacuation site information are, for example, sex information and age information included in the evacuation site information shown in FIG. The output determination unit 13 first sets the number of evacuation sites selected as output candidates to the number of terminals 10 or more, and the evacuation sites satisfying the condition that all the attributes indicated by the attribute information are included in the evacuation site information It is determined as evacuation site information to output information.

  For example, when the evacuation site information as output candidates is shown in FIG. 3, the number of users in the area is 50,000, and the user attribute is a 65-year-old woman, information output in the above-described embodiment The evacuation site information of “evacuation site 7”, which does not satisfy the age condition, is not output. The next evacuation site information of “evacuation site 5” is determined as information to be output in order to satisfy the conditions of the number of in-service users and all attributes.

  As described above, if the evacuation site information is output based on the user attribute, more appropriate distribution information can be output.

  In this embodiment, the distribution information whose output is determined is evacuation site information. However, any distribution information may be used as long as the position is associated and the information should be output according to the number of people in the area. May be information for which output is determined. In addition, the function deployment of the distribution system 20 according to the present embodiment is not necessarily performed in the xGSN 30 and the RNC 40 as in the present embodiment, and an arbitrary configuration can be taken.
