Technical Field

[0001] The present invention relates to a communication system for distributing disaster prevention information and the like. In particular, the present invention relates to a communication system that can transfer messages such as emergency information distributed by J-ALERT (National Instant Warning System) to a transfer destination that has a high degree of relevance to the content.

Background Art

[0002] [Prior Art] There is a text distribution system provided with an information distribution server that distributes information related to disasters as character information in a communication system for distributing disaster prevention information. The information distribution server text-distributes the distribution content registered in a database in advance to media that display character information such as various SNSs (Social Networking Services) and mail services. Here, the distribution is expressed as transfer, and the medium (media) to be transferred is expressed as the transfer destination. In addition to the text distribution system, there is an audio distribution system that distributes J-ALERT emergency information as audio.

[0003] [Related Art] Incidentally, as a related prior art, there is Japanese Patent Application Laid-Open No. 2013-106087, "Wireless Communication System" (Patent Document 1). Patent Document 1 shows that a control station does not transmit a siren sound portion in an emergency voice from J-ALERT or replaces it with another siren sound and transmits it to a slave station.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the communication system that forwards J-ALERT voice information to a destination is fixed in that it forwards to a pre-configured destination. As a result, depending on the content of the J-ALERT message, the message may be forwarded to an unrelated destination, which can lead to the problem of not being able to forward the message properly to the destination.

[0006] Furthermore, Patent Document 1 does not describe a configuration for selecting an appropriate forwarding destination and forwarding a message according to the content of the J-ALERT message.

[0007] This invention has been made in view of the above circumstances, and aims to provide a communication system that can select a highly relevant forwarding destination according to the content of the J-ALERT message and forward the message, thereby achieving appropriate forwarding related to the forwarding destination. [Means for solving the problem]

[0008] The present invention, which solves the problems of the above-mentioned conventional example, is a communication system for transferring J-ALERT emergency information to multiple media destinations, comprising: a receiving means for receiving message data of emergency information; a storage means having a destination condition table for registering keywords that are conditions for each candidate destination; a destination determination means for referring to the destination condition table for each candidate destination and determining a candidate destination according to the keywords in the received message data; and a transmission means for transmitting the message data to the determined destination. The forwarding destination determination means extracts place names within a specific distance range from the regional names included in the received message data, and if the extracted place names are registered as keywords in the forwarding destination condition table, the forwarding destination condition table determines the corresponding candidate forwarding destination as the forwarding destination. It is characterized by doing so.

[0009] The present invention is characterized in that, in the above-mentioned communication system, when a forwarding destination determination means contains a keyword registered in the forwarding destination condition table in the received message data, it determines a candidate forwarding destination corresponding to the forwarding destination condition table as the forwarding destination.

[0010] The present invention is characterized in that, in the above-mentioned communication system, if the forwarding destination determination means does not contain a keyword registered in the forwarding destination condition table in the received message data, it determines a candidate forwarding destination corresponding to the forwarding destination condition table as the forwarding destination.

[0011] The present invention is characterized in that, in the above-mentioned communication system, a plurality of keywords are registered in the forwarding destination condition table, and the forwarding destination determination means determines the forwarding destination by logical OR or logical AND of the plurality of keywords in the forwarding destination condition table.

[0012] The present invention is characterized in that, in the above-mentioned communication system, the keywords registered in the forwarding destination condition table include place names and disaster names. [Effects of the Invention]

[0014] According to the present invention, a communication system for transferring J-ALERT emergency information to multiple media destinations comprises: a receiving means for receiving emergency information message data; a storage means having a destination condition table for registering keywords that are conditions for each candidate destination; a destination determination means for referring to the destination condition table for each candidate destination and determining a destination candidate corresponding to the keywords in the received message data; and a transmission means for transmitting the message data to the determined destination. The forwarding destination determination means extracts place names within a specific distance range from the regional names included in the received message data, and if the extracted place names are registered as keywords in the forwarding destination condition table, the forwarding destination condition table determines the corresponding candidate forwarding destination as the forwarding destination. Because it is a communication system that allows for the selection of a relevant forwarding destination based on the content of the J-ALERT message, it has the effect of ensuring appropriate forwarding related to the destination. [Brief explanation of the drawing]

[Figure 3] This is a schematic diagram illustrating specific process 1. [Figure 4] This is a schematic diagram illustrating specific process 2.

Embodiments of the Invention

[0016] Embodiments of the present invention will be described with reference to the drawings. [Overview of Embodiment] A communication system (this system) according to an embodiment of the present invention is a communication system that transfers J-ALERT emergency information to transfer destinations of a plurality of media. The receiving means of the transfer device receives message data of the emergency information, the storage means has a transfer destination condition table in which keywords that are conditions for the transfer destination are registered for each transfer destination candidate (transfer destination candidate), and the transfer destination determination means refers to the transfer destination condition table for each transfer destination candidate, determines a transfer destination candidate corresponding to the keyword for the received message data as the transfer destination, and the transmission means transmits the message data to the determined transfer destination. Therefore, a transfer destination relevant to the message content of J-ALERT can be selected and the message can be transferred, and an appropriate transfer related to the transfer destination can be realized.

[0017] This system will be described with reference to FIG. 1. FIG. 1 is a schematic configuration diagram of this system. As shown in FIG. 1, this system basically includes a transfer device 1 and transfer destination media 21 to 23. Although three transfer destination media are shown in FIG. 1, the number of transfer destinations is arbitrary. Hereinafter, the transfer destination media may be simply referred to as "transfer destinations".

[0018] [Each Part] Each part of this system will be specifically described. [Transfer Device 1] The transfer device 1 is a device that inputs message data of J-ALERT emergency information, selects relevant message data according to the transfer destination media 21 to 22, and transfers it. The transfer device 1 includes a J-ALERT receiving means 11, a transfer destination determination means 12, a transfer destination condition table storage means 13, and a transmission means 14.

[0019] [J-ALERT receiving means 11] The J-ALERT receiving means 11 receives the message data of the emergency information from J-ALERT and outputs the text data contained in the message data to the forwarding destination determination means 12.

[0020] [Transfer destination determination means 12] The forwarding destination determination means 12, with respect to the text data contained in the message data input from the J-ALERT receiving means 11, refers to the forwarding destination condition table of candidate forwarding destinations stored in the forwarding destination condition table storage means 13 and determines whether or not the text data contains keywords registered in the forwarding destination condition table (whether or not they exist).

[0021] Then, if the text data contains keywords from the destination condition table, the destination determination means 12 selects a candidate destination corresponding to the destination condition table as the destination and outputs to the transmission means 14 to forward the message data to that destination.

[0022] [Transfer destination condition table storage means 13] The transfer destination condition table storage means 13 stores a transfer destination condition table for each candidate transfer destination (transfer destination media). The forwarding destination conditions table is associated with potential forwarding destinations, and contains keywords set and registered to determine whether or not to forward message data to the destination. There may be one or more keywords.

[0023] Furthermore, if there are multiple keywords, the transfer may be determined by the logical OR (OR) of the multiple keywords, or by the logical AND (AND) of the multiple keywords, or by combining the OR (+) and AND (*) of the multiple keywords.

[0024] For example, keywords A, B, and C can be used in an OR condition (A+B+C), an AND condition (A*B*C), or a combination of OR and AND conditions as (A+(B*C)).

[0025] In the above example, if a keyword exists in the destination condition table, it is selected (determined) as the destination. However, it would also be possible to select the destination if the keyword does not exist in the destination condition table. In other words, the destination is determined by the exclusive OR (NOR) of the keywords.

[0026] [Transmission means 14] The transmission means 14 transmits message data to the destination determined by the transfer destination determination means 12 in accordance with the communication method of the medium.

[0027] [Transfer destination media 21-23] The destination media 21-23 could be various media, such as various social networking services (SNS), email services, CATV (cable television) tickers, disaster prevention information systems, email, fax, etc. Therefore, the transmission means 14 will convert the message data to the communication method of the media described above and then transmit it.

[0028] [Overview of this system's processing: Figures 2-4] Next, the processing in this system will be explained with reference to Figures 2 to 4. Figure 2 is a schematic diagram showing the basic processing in this system, Figure 3 is a schematic diagram showing specific processing 1, and Figure 4 is a schematic diagram showing specific processing 2. In Figures 2-4, the upper (a) shows an overview of the system, and the lower (b) shows multiple destination condition tables.

[0029] [Basic processing: Figure 2] As shown in Figure 2, in this system, when the J-ALERT message data contains keyword 2, the destination determination means 12 of the transfer device 1 refers to the destination condition tables 31 to 33 corresponding to each destination media (destinations A to C) 21 to 23 stored in the destination condition table storage means 13.

[0030] Here, keyword 2 is registered as destination A condition in destination condition table 31, and keyword 2 is registered as destination C condition in destination condition table 33, so the destination determination means 12 selects destinations A and C.

[0031] The forwarding destination determination means 12 then instructs the transmission means 14 to select forwarding destinations A and C and send the J-ALERT message data. The transmission means 14 transmits the above message data to the destination media (destination A) 21 and the destination media (destination C) 23.

[0032] [Specific Procedure 1: Figure 3] As shown in Figure 3, specifically, when the J-ALERT message data contains the keyword "earthquake", the destination determination means 12 of the transfer device 1 refers to the destination condition tables 31 to 33 corresponding to each destination media (destinations A to C) 21 to 23 stored in the destination condition table storage means 13.

[0033] Here, the keyword "earthquake" is registered as destination A condition in destination condition table 31, and the keyword "earthquake" is registered as destination C condition in destination condition table 33. Therefore, the destination determination means 12 selects destinations A and C.

[0034] The destination determination means 12 then instructs the transmission means 14 to select destinations A and C and send the J-ALERT message data, and the transmission means 14 sends the message data to destination media (destination A) 21 and destination media (destination C) 23.

[0035] [Specific Processing 2: Figure 4] As shown in Figure 4, specifically, when the J-ALERT message data contains the keyword "○○ City", the destination determination means 12 of the transfer device 1 refers to the destination condition tables 31 to 33 corresponding to each destination media (destinations A to C) 21 to 23 stored in the destination condition table storage means 13.

[0036] Here, the forwarding destination condition table 31 has the keyword "○○ City" registered as forwarding destination condition A, and the forwarding destination condition table 32 has the keyword "○○ City" registered as forwarding destination condition B. Therefore, the forwarding destination determination means 12 selects forwarding destination A or B. Note that the forwarding destination condition table 33 has "△△ City" registered as forwarding destination condition C, and does not contain the keyword "○○ City," so it does not meet the conditions.

[0037] The destination determination means 12 then instructs the transmission means 14 to select destinations A and B and send the J-ALERT message data, and the transmission means 14 sends the message data to destination media (destination A) 21 and destination media (destination B) 22.

[0038] [Another process] Additionally, as explained in the forwarding destination conditions table, J-ALERT message data may be forwarded only if a specific keyword is not included. For example, if a message does not contain the keyword "tsunami," it will not be forwarded to coastal municipalities, but to other municipalities. In this case, information on whether or not the municipality's name is coastal is associated with it and stored in the forwarding destination condition table storage means 13, and the forwarding destination determination means 12 makes a decision based on that association information.

[0039] In addition, users can register detailed earthquake information such as "magnitude 4" or "magnitude 5+", and messages can be forwarded for earthquakes of a certain magnitude or higher. Users can also register natural place names such as "〇〇 River" or "△△ Lake", and messages can be forwarded to media in nearby cities, towns, or villages, for example, near "〇〇 River".

[0040] Furthermore, by setting the keywords as a logical AND of "XX City" and "XX River," messages can be forwarded only if both keywords are included. Alternatively, you could set up a logical OR operation between the two keywords mentioned above, so that the message is forwarded if either of the two keywords is included.

[0041] [Editing the transfer destination condition table] Next, we will explain the process of editing the transfer destination conditions table. The destination condition table stored in the destination condition table storage means 13 allows the administrator of the destination media to edit keywords from an external source. However, if editing were completely unrestricted, J-ALERT emergency information messages would not be forwarded, so we have imposed one of the following restrictions.

[0042] Firstly, the editing process for the forwarding destination conditions table will only allow the addition of keywords. Keywords that were initially set will remain, so there will be no cases where related messages are not forwarded.

[0043] Secondly, the editing process for the transfer destination conditions table periodically notifies the administrator when a keyword is deleted and then restored. This prevents important keywords from being left deleted. The notification to the administrator is made from transfer device 1.

[0044] Thirdly, the editing process for the transfer destination conditions table is restricted so that basic keywords (keywords set by our organization) cannot be deleted or edited, and only additional keywords can be deleted or edited. This allows transfers to the initially set destination while also allowing administrators to arbitrarily select the transfer destination at their discretion, thereby improving usability.

[0045] Furthermore, the transfer device 1 may acquire information on the central point (coordinates) of the municipality of the destination media and present recommended keyword candidates to the administrator based on this coordinate information. This involves pre-storing keyword candidates corresponding to the coordinates in the destination condition table storage means 13, and the transfer device 1 notifying the administrator's terminal. This helps the administrator to edit the destination condition table appropriately.

[0046] [Application Examples] Next, we will explain some application examples of this system. The forwarding destination determination means 12 of the forwarding device 1 extracts place names (second place names) within a specific distance, for example, a radius of 50 km, from a place name (first place name) included in the J-ALERT message data, for example, from a stored hazard map. If the extracted place name is a keyword in the forwarding destination condition table, the forwarding data is forwarded to the forwarding destination corresponding to that forwarding destination condition table.

[0047] Rather than simply determining whether a keyword (the first keyword) contained in the message exists in the destination condition table, the destination determination means 12 determines the destination based on whether a second keyword, extracted as a result of specific information processing from the first keyword, exists in the destination condition table. The above application examples allow for a more appropriate selection of the forwarding destination.

[0048] [Effects of the embodiment] According to this system, a receiving means 11 receives emergency information message data, a forwarding destination condition table storage means 13 has a forwarding destination condition table in which keywords that serve as conditions for forwarding destinations are registered for each forwarding destination candidate, a forwarding destination determination means 12 refers to the forwarding destination condition table for each forwarding destination candidate to determine a forwarding destination candidate according to the keywords for the received message data, and a forwarding device 14 transmits the message data to the determined forwarding destination. As such, it is possible to select a forwarding destination that is relevant to the content of the J-ALERT message and forward the message, and it has the effect of achieving appropriate forwarding related to the forwarding destination. [Industrial applicability]

[0049] The present invention is suitable for a communication system that can select a highly relevant forwarding destination according to the content of a J-ALERT message and forward the message, thereby achieving appropriate forwarding related to the destination. [Explanation of Symbols]
