DETAILED DESCRIPTION OF THE INVENTION

[0013] First, an overview of one embodiment of the present disclosure will be described with reference to the drawings. Note that the reference numerals in this overview are added to each element for convenience as an example to facilitate understanding, and are not intended to limit the present disclosure to the illustrated form. Furthermore, connecting lines between blocks in the drawings and the like referred to in the following description include both bidirectional and unidirectional lines. Unidirectional arrows are used to schematically indicate the flow of main signals (data) and do not exclude bidirectionality. A program is executed via a computer device, which includes, for example, a processor, a storage device, an input device, a communication interface, and, if necessary, a display device. Furthermore, this computer device is configured to be able to communicate with internal or external devices (including computers) via the communication interface, whether wired or wireless. Furthermore, ports or interfaces are present at the input / output connection points of each block in the drawings, but are not shown.

[0014] In one embodiment, the present disclosure can be realized by a broadcast control server 10, which includes a template information storage unit 11, a broadcast condition storage unit 12, a broadcast reception unit 13, and a transmission control unit 14, as shown in Fig. 1. More specifically, the template information storage unit 11 stores template information that defines the sender, the broadcast destination, and the content of the broadcast message (see Fig. 2).

[0015] The broadcast condition storage unit 12 stores, for each event, broadcast conditions that define the conditions for sending the broadcast message defined in the template information (see FIG. 2).

[0016] When the broadcast reception unit 13 receives a broadcast request including event identification information for identifying the event from a sender, it selects a template from the broadcast condition storage unit and determines the sender, broadcast destination, and broadcast message content defined in the template.

[0017] The transmission control unit 14, in accordance with an instruction from the broadcast reception unit 13, transmits the contents of the broadcast message in which the sender is set to the broadcast destinations.

[0018] The broadcast control server 10 configured as described above operates as follows. First, when the broadcast control server 10 receives a broadcast request from a sender that includes event identification information for identifying the event, it selects a template from the broadcast condition storage unit. In this example, the broadcast request received is that event A has occurred. "Event A-T1" in the upper right balloon in FIG. 3 means that template T1 will be selected when event A occurs. In this case, the broadcast control server 10 selects template T1 that corresponds to event A.

[0019] Next, the broadcast control server 10 reads the template information of the selected template T1 and determines the broadcast destinations and the content of the broadcast message. "T1 | Event A | a, b, c, ... | Event A occurs" in the speech bubble at the top right of Fig. 3 is an example of template information for template T1, with "a, b, c, ..." representing the destination list and "Event A occurs" representing the content of the broadcast message. The broadcast control server 10 creates a broadcast message addressed to each of the above-mentioned broadcast destinations in the broadcast reception unit 13 and sends it from the transmission control unit 14 (see "Destination a, Sender A, "Event A occurs"" in the speech bubble at the bottom right of Fig. 3 and subsequent lines). Note that in the above explanation, the symbol "|" indicates a delimiter.

[0020] As described above, according to the present disclosure, by simply issuing a broadcast request including event-specific information, it becomes possible to set the broadcast destinations and broadcast message content and simultaneously transmit the broadcasts. In other words, the present disclosure can significantly reduce the work of inputting broadcast requests in a broadcast system.

[0021] [First embodiment] Next, an embodiment of the present disclosure will be described in detail with reference to the drawings. Fig. 4 is a diagram showing a first configuration in which the present disclosure is applied to a broadcast system that performs broadcasting using an IP network. Referring to Fig. 4, a configuration is shown in which a broadcast control server 100, a management terminal 120, an IP telephone 210, an IP-FAX 220, and a mail server 230 are connected to an IP network 500.

[0022] The management terminal 120 is a terminal for managing the template information and broadcast conditions held by the broadcast control server 100. The management terminal 120 displays a maintenance screen and provides functions such as registering, changing, and deleting template information and broadcast conditions, and checking the registered contents. The management terminal 120 can also be realized by a web server or the like on a network. In this case, the broadcast control server 100 and the management terminal 120 are connected via the Internet or the like. The management terminal 120 displays a maintenance screen to users who access it and sends the received contents to the broadcast control server 100.

[0023] The other devices that receive the broadcast messages from the broadcast control server 100 are the IP telephone 210, the IP-FAX 220, and the mail server 230. The types and number of devices that receive the broadcast messages, such as the IP telephone 210, the IP-FAX 220, and the mail server 230 shown in Figure 4, are merely examples, and it is not necessary for all of them to be the recipients of the broadcast messages. For example, the configuration may be such that only the broadcast control server 100 and the mail server 230 are connected to the IP network 500.

[0024] The mail server 230 transmits the broadcast message entrusted by the broadcast control server 100 to the smartphone 240 and the PC (personal computer) 250 in the form of a broadcast email via the Internet or the like.

[0025] 5 is a diagram showing a broadcast control server of the first configuration of the present disclosure. Referring to FIG. 5, broadcast control server 100 includes template information storage unit 101, broadcast condition storage unit 102, broadcast reception unit 103, transmission control unit 104, and broadcast reception table 105.

[0026] The template information storage unit 101 stores template information that defines the template name, sender, multicast group, and multicast message content. FIG. 6 is a diagram showing an example of template information stored in the template information storage unit 101. The sender in FIG. 6 is information that will be the sender's name for the multicast message. This sender's name may be different from the sender information in the multicast conditions, which will be described later. The multicast group is the name of a group of addresses that will be the multicast destinations, which have been set in advance. For example, template T1 is a template that notifies recipients belonging to group a of the occurrence of "event A" in the name of sender A. As shown in FIG. 6, by creating multiple template information according to the type of event and sender name, it is possible to change the content and destination of the multicast message depending on the sender, even for the same event.

[0027] In the example of Fig. 6, the content of the broadcast message is simply "Event A," but the format of the broadcast message is not limited to this. For example, as shown in Fig. 7, a broadcast message informing of the occurrence of an earthquake can be created in advance and registered in template information storage unit 101, allowing broadcast messages of any content to be sent. For example, even for the same earthquake event, by preparing templates with different broadcast message content depending on the seismic intensity, distance from the epicenter, etc., it is possible to send broadcast messages with different content depending on the seismic intensity, distance from the epicenter, etc. Of course, by preparing a broadcast group in advance, it is also possible to change the recipients of the broadcast messages.

[0028] The broadcast condition storage unit 102 stores, for each event, broadcast conditions that define the conditions for sending a broadcast message defined in the template information. Fig. 8 is a diagram showing an example of broadcast conditions stored in the broadcast condition storage unit 102. The example in Fig. 8 shows broadcast conditions that link an event name, a sender, and a template name. For example, when sender A requests the occurrence of event A, template T1 is used. Similarly, when sender B requests the same event A, template T2 is used. In this way, it is possible to change the template to be sent even for the same event.

[0029] The broadcast reception unit 103 receives a broadcast request including sender information from a sender, determines the broadcast destination and broadcast content, and requests the transmission control unit 104 to send the broadcast message. This broadcast request can be made by a user who has been given permission in advance, or by a user of the IP telephone 210, IP-FAX 220, smartphone 240, or PC 250.

[0030] Furthermore, broadcast reception unit 103 can use various methods to receive broadcast requests from these devices, such as various forms or an automated voice reception function. For example, when a user of IP telephone 210 requests broadcast control server 100 to send a broadcast message informing the user of event A, the user of IP telephone 210 calls a telephone number that has been notified in advance. Broadcast reception unit 103 or a voice guidance service that operates in cooperation with broadcast reception unit 103 receives the broadcast request by prompting the user of IP telephone 210 to enter information using an automated voice.

[0031] It is also possible to construct a dedicated site for multicast requests on the Internet and accept multicast requests from each user. In this case, the information previously entered by each user can be stored for a predetermined period of time in a form or on the multicast control server 100. By providing a function to initially display the information previously entered the next time the user logs in, the user's operation can be further simplified.

[0032] The multicast reception unit 103 refers to the multicast condition storage unit 102 and determines the template information to be sent from the event information and sender information included in the multicast request. The multicast reception unit 103 then reads the sender, destination group, and broadcast message content of the determined template from the template information storage unit 101 and records them in the multicast reception table 105.

[0033] The transmission control unit 104 creates a broadcast message for the specified sender by referring to the contents recorded in the broadcast reception table 105, and sends it to the destinations set in the broadcast destination group. If the transmission is successful, the transmission control unit 104 changes the broadcast status field of the corresponding entry in the broadcast reception table 105 from "Delivery accepted" to "Delivered."

[0034] The broadcast reception table 105 is a table that holds entries that have fields for the template sender, the broadcast destination group, the broadcast message content, as well as the reception date and time and broadcast status. In this embodiment, this broadcast reception table 105 is used to manage the sending of broadcast messages. Also, by referencing this broadcast reception table 105, the implementation status of broadcasting can be confirmed.

[0035] Next, the operation of one embodiment of the present disclosure will be described in detail with reference to the drawings. Fig. 9 is a sequence diagram for explaining the operation of the first configuration of the present disclosure. In Fig. 9, the source of the broadcast request is one of the users of the IP telephone 210, IP-FAX 220, smartphone 240, and PC 250.

[0036] When a broadcast request is received from a broadcast request source (step S001), the broadcast receiving unit 103 of the broadcast control server 100 acquires the event name and sender information from the broadcast request. The event name may be received in the form of a predetermined event ID or the like.

[0037] Next, the broadcast reception unit 103 of the broadcast control server 100 identifies a template corresponding to the acquired event name and sender from the broadcast condition storage unit 102. Furthermore, the broadcast reception unit 203 of the broadcast control server 100 identifies the template information of the identified template from the template information storage unit 101. This completes the identification of the broadcast content (step S002). Note that there may be cases where it is not possible to identify a template corresponding to the event name and sender, such as in the case of a broadcast request from an unregistered sender. In such cases, the broadcast reception unit 103 does not send the broadcast message. In other words, the broadcast control server 100 rejects broadcast transmissions from senders other than those registered in the broadcast condition storage unit 102. This makes it possible to prevent broadcast messages from being distributed by pranks or erroneous operations.

[0038] Next, the broadcast reception unit 103 of the broadcast control server 100 registers the specified broadcast content in the broadcast reception table 205 (step S003). Furthermore, the broadcast reception unit 203 of the broadcast control server 100 instructs the transmission control unit 204 to start broadcasting (step S004).

[0039] Upon receiving the instruction, transmission control unit 104 reads entries one by one from broadcast reception table 105 and starts delivering the broadcast message to the specified destinations (step S005). Furthermore, when transmission control unit 104 receives a delivery result from a broadcast destination device (step S006), it changes the corresponding entry in broadcast reception table 105 to "delivered" (step S007). Note that in the example of Fig. 9, the delivery result is received from the broadcast destination device after transmission control unit 104 has completed delivery of the broadcast message, but it is also possible to receive a delivery result from the broadcast destination device each time a broadcast message is delivered.

[0040] When the series of processes is completed, the transmission control unit 104 notifies the multicast reception unit 103 that the multicast has been completed (step S008).

[0041] As described above, this embodiment allows you to select an appropriate template depending on the content of the event and distribute it to the appropriate recipients. In particular, when the same sender sends different broadcast messages depending on the type of event, it is possible to reduce the effort required to set and confirm the recipients.

[0042] [Second embodiment] Next, a second embodiment will be described in which an event detection function is added to the broadcast control server 100a. Fig. 10 is a diagram showing another example of the configuration of the broadcast control server of the present disclosure. The difference from the example of the configuration shown in Fig. 5 is that the broadcast control server 100a has added thereto a function in which the event detection unit 106 delivers a broadcast message via the event detection unit 106. The other configurations are the same as those in Fig. 5, so the following description will focus on the differences.

[0043] The event detection unit 106 is connected to sensors S such as a seismic intensity meter, a fire alarm, an infrared sensor, and a thermometer. When the sensor S detects an event such as the occurrence of an abnormality, the event detection unit 106 transmits a broadcast request including information about the event that has occurred to the broadcast reception unit 103. In this embodiment, the event detection unit 106 acts as the sender of the broadcast request.

[0044] FIG. 11 is a diagram showing another example of template information stored in template information storage unit 101. The sender in FIG. 11 is information for identifying sensors of different types and locations. The broadcast destination group is the name of a group of addresses that will be broadcast destinations set in advance. For example, template T11 is a broadcast message notifying of an abnormality in sensor A, and is a template that notifies destinations belonging to group aa that an "abnormality in sensor A" has occurred. As shown in FIG. 11, by creating multiple template information according to the type, location, and nature of the abnormality of the sensor, it is possible to change the content of the broadcast message and the broadcast destination depending on the nature of the event that has occurred.

[0045] Fig. 12 is a diagram showing another example of the broadcast conditions stored in the broadcast condition storage unit 102. The example in Fig. 12 shows broadcast conditions that link an event name, a sender, and a template name. For example, the template used when an abnormality in sensor A is notified from sensor A is template T11. Furthermore, when the details of the abnormality or sensor values ​​are sent from sensor A, the template may be changed depending on the details.

[0046] When broadcast reception unit 103a receives a broadcast request from event detection unit 106, it refers to broadcast condition storage unit 102 and determines the template information to be broadcast from the information on the event that has occurred and the sender information included in the broadcast request. As described above, by preparing broadcast conditions that define the information on each sensor as sender information, broadcast reception unit 103a can identify template information based on the combination of the relevant sensor and event.

[0047] The multicast reception unit 103 a then reads out the sender, multicast group and multicast message content of the determined template from the template information storage unit 101 , and records them in the multicast reception table 105 .

[0048] Fig. 13 is a sequence diagram for explaining the operation of the second configuration of the present disclosure. The first operational difference from the first embodiment shown in Fig. 9 is that in step S101, the sensor S notifies the occurrence of an abnormality (step S101). The second operational difference from the first embodiment is that the event detection unit 106 analyzes the type of the source sensor S and the data received from the sensor S to determine the content of the event. The third operational difference from the first embodiment is that the event detection unit 106 notifies the broadcast reception unit 103a of the occurrence of the event (step S102). The subsequent operations are the same as those in the first embodiment, and therefore will not be described.

[0049] As described above, according to this embodiment, broadcast messages can be distributed without waiting for manual reporting. In the example of FIG. 13, the event detection unit 106 is described as automatically notifying the broadcast reception unit 103a of the occurrence of an event, but it is also possible to configure the system so that final confirmation by an operator or the like is required. In this case, for example, after receiving data from sensor S, the broadcast control server 100a requests confirmation of the data from sensor S from an operator or the like. Then, after receiving final confirmation from the operator or the like, the broadcast control server 100a notifies the occurrence of an event. In this way, it is possible to prevent so-called false alarms from occurring.

[0050] In the above description, an example in which a sensor S is connected to the event detection unit 106 has been described. However, modifications are possible so that the broadcast control server 100a detects the occurrence of an event using other information. For example, a modification can be made so that the broadcast control server 100a obtains information from various servers on the Internet instead of the sensor S. For example, the same effect can be achieved by having the broadcast control server 100a receive disaster information or news from these servers and detect the occurrence of an event. Furthermore, the various servers may include a time information providing server such as an NTP (Network Time Protocol) server. In this way, it becomes possible for the broadcast control server 100a to automatically distribute a broadcast message at a certain time.

[0051] [Third embodiment] Next, a third embodiment will be described in which a function for identifying the sender from the content of an event is added to the broadcast control server 100b. Fig. 14 is a diagram showing another example of the configuration of the broadcast control server of the present disclosure. The differences from the example of the configuration shown in Fig. 10 are that an event table 107 is added to the broadcast control server 100b and that a sender identification unit 1061 is added to the event detection unit 106b. Since the other configurations are the same as those in Fig. 10, the following description will focus on the differences.

[0052] Fig. 15 is a diagram showing an example of event information stored in the event table 107. The example of Fig. 15 shows a table that stores entries linking event information of a monitored object with information about its sender. For example, in the example of Fig. 13, sender A is linked to event A, and sender B is linked to event A and event B.

[0053] When sender identification unit 1061 in event detection unit 106b detects the occurrence of an event, it refers to event table 107 to identify the sender of the event that has occurred. For example, when event A in Fig. 13 occurs, sender identification unit 1061 refers to event table 107 to identify the sender. At this time, if multiple senders are set, as in event A in Fig. 13, event detection unit 106b considers that two events have occurred, and transmits a broadcast request including information about the occurred events to broadcast reception unit 103.

[0054] When a broadcast request is received from the event detection unit 106b, the broadcast reception unit 103b refers to the broadcast condition storage unit 102 and determines the template information to be broadcast from the information on the occurring event and the sender information included in the broadcast request. The other operations are the same as those in the first embodiment, so a description thereof will be omitted.

[0055] Fig. 16 is a sequence diagram for explaining the operation of the third configuration of the present disclosure. The difference in operation from the second embodiment shown in Fig. 13 is that in step S102a, event detection unit 106b refers to event table 107 to determine the content and sender of the event. Then, event detection unit 106b notifies broadcast reception unit 103b of the occurrence of the event and its sender (step S102a). The subsequent operation is the same as in the first embodiment, so a description thereof will be omitted.

[0056] As described above, this embodiment makes it possible to generate a broadcast request with an appropriate sender set for a given event, create an appropriate broadcast message, and broadcast the message. As described above, because a template is selected using sender information in addition to the event that occurred, it is possible to create a more detailed broadcast message and distribute it simultaneously to appropriate recipients. For example, there may be cases where different broadcast messages are desired for the same event, such as an earthquake. For example, it is possible to simultaneously send a first broadcast message to fire prevention personnel informing them of the earthquake, with the sender being a fire department officer, and a second broadcast message to system personnel informing them of the earthquake, with the sender being system headquarters. Furthermore, in this embodiment, by using different template information for each message, the broadcast range of the first broadcast message and the broadcast range of the second broadcast message can be set to different ranges.

[0057] [Fourth embodiment] Next, a fourth embodiment will be described in which the event detection function of the broadcast control server 100b of the third embodiment is arranged in an external server. Fig. 17 is an overall diagram for explaining the fourth configuration of the present disclosure. The difference from the configuration example shown in Fig. 14 is that an event detection server 300 is connected to an IP network 500. In addition, various sensors S are connected to the event detection server 300.

[0058] The event detection server 300 is an external device in which the event detection unit of the third embodiment is separated from the broadcast control server 100. Fig. 18 is a diagram showing an example of the configuration of the event detection server 300 of the present disclosure. Referring to Fig. 18, the event detection server 300 includes an event detection unit 306 and an event table 307. The event detection unit 306 includes a sender identification unit 3061.

[0059] The contents stored in the event table 307 are the same as those of the event table 107 in the third embodiment, and therefore a description thereof will be omitted. The function of the event detection unit 306 is also the same as that of the event detection unit 106b in the third embodiment, and therefore a description thereof will be omitted.

[0060] 19 is a sequence diagram for explaining the operation of the fourth configuration of the present disclosure. Except for the fact that the operation of the event detection unit 106b is replaced by the event detection server 300, the operation is the same as that of the third embodiment shown in FIG. 16, and therefore a description thereof will be omitted.

[0061] As described above, according to this embodiment, it is possible to set an appropriate sender for an event that has occurred, create an appropriate broadcast message, and distribute the message by broadcast, as in the third embodiment. Note that, although the above description has been given assuming that the event detection server 300 has a function equivalent to the event detection unit 306b in the third embodiment, it is also possible to adopt a configuration in which the event detection server 300 has a function equivalent to the event detection unit 306 in the second embodiment.

[0062] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments, and further modifications, substitutions, and adjustments can be made without departing from the basic technical concept of the present disclosure. For example, the network configuration, element configuration, and data representation format shown in each drawing are examples to aid in understanding the present disclosure, and are not limited to the configurations shown in these drawings.

[0063] For example, in the above-described embodiments, the multicast control server 100 and the multicast destination device are connected via the IP network 500, but the scope of application of the present disclosure is not limited to this. For example, the present disclosure can be similarly applied to a case where the multicast control server 100 and the multicast destination device are connected via the Internet or a dedicated line network.

[0064] (About hardware configuration) In each embodiment of the present disclosure, each component of each device represents a functional block. Some or all of the components of each device are realized by any combination of an information processing device 900 and a program, for example, as shown in Fig. 20.
