Description

[Technical field]

[0001] The present invention relates to a communication device, a communication system, and a communication method that enable easy contact. [Background technology]

[0002] In organizations such as the police and fire departments, each organization has its own dedicated communication line. For example, the fire department uses a digital communication line in the 260MHz band. In addition to such conventional dedicated lines, the addition of a dedicated LTE (Long Term Evolution) line (called PS (Public Safety)-LTE) is being considered. A network is being constructed using such lines.

[0003] For example, Patent Document 1 discloses a wireless terminal that can be connected to a plurality of networks. Patent Documents 2 and 3 also disclose related techniques. [Prior art documents] [Patent documents]

[0005] It is assumed that each organization will use a dedicated LTE line in addition to the conventional dedicated line. In this case, members of each organization will use both terminals for the conventional dedicated line and terminals for the dedicated LTE line. In this case, a person who wants to contact a member inputs the identification information assigned to the member into the system, and the system communicates with both the conventional dedicated line destination and the LTE line destination associated with the identification information.

[0006] In the above case, it was not possible to select which of the two terminals to use for communication, which was troublesome for the terminal owner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] <First embodiment> A communication system 1 in the first embodiment will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a block diagram showing an example of the configuration of the communication system 1. Fig. 2 is a sequence diagram showing an example of the operation of the communication system 1.

[0014] As shown in FIG. 1, the communication system 1 includes a first terminal 10, a communication device 20, a first network 30, a second network 40, a first communication module 50, and a second communication module 60.

[0015] The first terminal 10 transmits communication information including identification information of a destination user to the communication device 20. The communication information may be, for example, a call request to the destination user, voice data to the destination user, a chat participation notification, or video data. The first terminal 10 is a terminal having a communication function, and may be, for example, a wireless device, a smartphone, a PC (Personal Computer), or a server.

[0016] The communication device 20 includes a receiving means 21, a selecting means 22, and a transmitting means 23. The communication device 20 may be, for example, a smartphone, a PC, or a server.

[0017] The receiving means 21 receives communication information including identification information of a destination user from the first terminal 10. The receiving means 21 notifies the selecting means 22 of the identification information included in the communication information. The receiving means 21 also outputs the communication information to the transmitting means 23.

[0018] The selection means 22 selects at least one of the first network 30 to which the first communication module 50 associated with the user can be connected and the second network 40 to which the second communication module 60 associated with the user can be connected based on the identification information. For example, the selection means 22 stores a correspondence between the first network 30 or the second network 40 and the identification information. In this case, the selection means 22 refers to the correspondence and selects the network associated with the identification information. The selection means 22 may not store the correspondence between the first network 30 or the second network 40 and the identification information, but may obtain it from an external server. Also, the destination user may set in advance which of the first network 30 or the second network 40 is to be associated with his / her own identification information.

[0019] The first network 30 and the second network 40 are different networks. For example, the first network 30 is an LTE line, and the second network 40 is a digital communication line in the 260 MHz band. The first network 30 and the second network 40 may be operated by different carriers.

[0020] The selection means 22 prestores a first priority set for the first network 30 and a second priority set for the second network 40. In this case, the selection means 22 may compare the first priority and the second priority and select the network with the higher priority between the first network 30 and the second network 40.

[0021] The first priority and the second priority are set according to at least one of the type of the user and the type of communication information to be the destination. The type of user is, for example, the position of the user in an organization. In this case, the higher the position of the user, the higher the first priority is set and the lower the second priority is set. As a result, the selection means 22 can select an LTE line that is faster than a digital communication line in the 260 MHz band for a user with a higher position. Also, the type of communication information is at least one of the importance or urgency of the communication information. In this case, the higher the importance or urgency, the higher the first priority is set and the lower the second priority is set. As a result, the selection means 22 can select an LTE line that is faster than a digital communication line in the 260 MHz band for communication information with high importance or urgency. It is assumed that the importance or urgency of the communication information is included in the communication information from the first terminal 10.

[0022] The transmitting means 23 transmits information related to the communication information to a communication module that can connect to the selected network out of the first communication module 50 and the second communication module 60, via the network selected by the selecting means 22. When the first network 30 is selected by the selecting means 22, the transmitting means 23 transmits information related to the communication information to the first communication module 50. When the second network 40 is selected by the selecting means 22, the transmitting means 23 transmits information related to the communication information to the second communication module 60.

[0023] The information on the communication information is, for example, information including at least the communication information transmitted from the first terminal 10, or information indicating that the communication information has been transmitted to the user from the first terminal 10. Here, the information on the communication information is generated, for example, by the transmitting means 23 extracting data included in the communication information received by the receiving means 21 and assigning the address of the first communication module 50 or the second communication module 60 to the data.

[0024] For example, when the communication information received by the receiving means 21 from the first terminal 10 includes text data, audio data, or video data, the transmitting means 23 transmits information on the communication information including these data to the first communication module 50 or the second communication module 60. In addition, when the communication information received by the receiving means 21 from the first terminal 10 includes a call request with a user, a notification to join a chat, audio data, or video data, the transmitting means 23 may transmit a connection establishment request from the first terminal 10 as information on the communication information to the first communication module 50 or the second communication module 60 instead of these data. When the first communication module 50 or the second communication module 60 responds to the connection establishment request, the first terminal 10 performs a call with the user, a chat communication, or transmits audio data and video data through the connection, not through the communication device 20.

[0025] The first communication module 50 is assigned an address (e.g., an Internet Protocol (IP) address or an individual number) in the first network 30. The second communication module 60 is assigned an address (e.g., an IP address or an individual number) in the second network 40. The first communication module 50 and the second communication module 60 may be provided in different communication terminals, or may be provided in the same communication terminal.

[0026] The operation of the communication system 1 will be described with reference to Fig. 2. The first terminal 10 transmits communication information to the receiving means 21 (S101). The receiving means 21 acquires user identification information from the received communication information (S102). The receiving means 21 outputs the identification information included in the received communication information to the selecting means 22 (S103). The receiving means 21 also outputs the received communication information to the transmitting means 23 (S104).

[0027] The selection means 22 selects, based on the identification information, the first network 30 to which the first communication module 50 can be connected or the second network 40 to which the second communication module 60 can be connected (S105). At this time, the selection means 22 selects at least one of the first network 30 and the second network 40 that is associated with the identification information. The selection means 22 notifies the transmission means 23 of the selected network (S106).

[0028] The transmitting means 23 generates information on the communication information based on the communication information acquired from the receiving means 21 (S107). The transmitting means 23 transmits information on the communication information to the communication module connectable to the network selected by the selecting means 22. Specifically, when the transmitting means 23 is notified by the selecting means 22 that the first network 30 has been selected, the transmitting means 23 transmits information on the communication information to the first communication module 50 via the first network 30 (S108). Also, when the transmitting means 23 is notified by the selecting means 22 that the second network 40 has been selected, the transmitting means 23 transmits information on the communication information to the second communication module 60 via the second network 40 (S109). Also, when the transmitting means 23 is notified by the selecting means 22 that the first network 30 and the second network 40 have been selected, the transmitting means 23 transmits information on the communication information to the first communication module 50 via the first network 30 (S110). In this case, the transmitting means 23 further transmits information related to the communication information to the second communication module 60 via the second network 40 (S111).

[0029] As described above, the communication device 20 includes a receiving means 21, a selecting means 22, and a transmitting means 23. The receiving means 21 receives communication information including the identification information of a destination user from a first terminal. The selecting means 22 selects, based on the identification information, either a first network 30 to which a first communication module 50 associated with the user can be connected or a second network 40 different from the first network 30 to which a second communication module 60 associated with the user can be connected. The transmitting means 23 transmits information related to the communication information to a communication module that can be connected to the network selected by the selecting means 22, out of the first communication module 50 and the second communication module 60, via the network selected by the selecting means 22.

[0030] As described above, the communication device 20 selects at least one of the first network 30 and the second network 40 selected by the selection means 22, and transmits information related to the communication information via a communication module connectable to the selected network. Therefore, even if the user has multiple communication modules connectable to different networks, it is possible to select at least one and transmit information related to the communication information. In this case, the information related to the communication information is received from the selected one of the multiple communication modules owned by the user, so the user can easily grasp the information related to the communication information. In this way, the communication device 20 makes it possible to easily contact the user.

[0031] <Second embodiment> A communication system 2 in the second embodiment will be described with reference to Fig. 3 and Fig. 4. Fig. 3 is a block diagram showing a configuration example of the communication system 2. Fig. 4 is a sequence diagram showing an operation example of the communication system 2. The communication system 2 includes a communication device 20, a first network 30, a second network 40, a first communication module 50, and a second communication module 60. The communication system 2 differs from the communication system 1 in that the communication device 20 further includes a monitoring means 24.

[0032] The monitoring means 24 monitors both the connection state between the first network 30 and the first communication module 50 and the connection state between the second network 40 and the second communication module 60. Specifically, the monitoring means 24 monitors whether the first communication module 50 can communicate with the communication device 20 via the first network 30. For example, the monitoring means 24 transmits a response request to the first communication module 50 via the first network 30. In this case, the monitoring means 24 monitors whether the first communication module 50 can communicate with the communication device 20 depending on whether a response from the first communication module 50 is received within a predetermined period. In addition, the monitoring means 24 monitors whether the second communication module 60 can communicate with the communication device 20 via the second network 40. For example, the monitoring means 24 transmits a response request to the second communication module 60 via the second network 40. In this case, the monitoring means 24 monitors whether the second communication module 60 is able to communicate with the communication device 20 depending on whether a response from the second communication module 60 is received within a predetermined period of time. The monitoring means 24 may cause the transmitting means 23 to transmit a response request, or may cause the receiving means 21 to receive a response to the response request. The monitoring means 24 stores as a monitoring result whether each communication module is able to connect to the network.

[0033] In the communication system 2, the selection means 22 refers to the monitoring results by the monitoring means 24 and selects the first network 30 or the second network 40 based on the monitoring results. For example, when the monitoring means 24 determines that the first communication module 50 is in a state where it can be connected to the first network 30 and the second communication module 60 is in a state where it cannot be connected to the second network 40, the selection means 22 selects the first network 30. Note that the "referencing" here may mean that the selection means 22 accesses the monitoring means 24 to obtain data indicating the monitoring results, or may mean that the monitoring means 24 outputs data indicating the monitoring results to the selection means 22.

[0034] In addition, if the monitoring means 24 determines that the first communication module 50 is unable to connect to the first network 30 and the second communication module 60 is able to connect to the second network 40, the selection means 22 selects the second network 40.

[0035] Furthermore, when the monitoring means 24 determines that the first communication module 50 is in a state capable of being connected to the first network 30 and the second communication module 60 is in a state capable of being connected to the second network, the selection means 22, similar to the communication system 1, selects the first network 30 or the second network 40 based on the identification information or the first priority set for the first network 30 and the second priority set for the second network 40.

[0036] The operation of the communication system 2 will be described with reference to Fig. 4. S101 to S104 and S106 to S111 The processing is similar to the processing in steps S101 to S104 and S106 to S111 in the communication system 1 shown in FIG. 2, and therefore a description thereof will be omitted.

[0037] In the communication system 2, the monitoring means 24 transmits a response request to the first communication module 50 (S201). The first communication module 50 responds to the received response request (S202). The monitoring means 24 transmits the response request to the second communication module 60 (S203). The second communication module 60 responds to the received response request (S204).

[0038] The monitoring means 24 stores the monitoring result (S205). Specifically, when there is a response from the first communication module 50, the monitoring means 24 stores that the first communication module 50 can be connected to the first network 30. Furthermore, when there is no response from the first communication module 50 within a predetermined period, the monitoring means 24 stores that the first communication module 50 cannot be connected to the first network 30. Furthermore, when there is a response from the second communication module 60, the monitoring means 24 stores that the second communication module 60 can be connected to the second network 40. Furthermore, when there is no response from the second communication module 60 within a predetermined period, the monitoring means 24 stores that the second communication module 60 cannot be connected to the second network 40.

[0039] The selection means 22 refers to the monitoring result stored by the monitoring means 24 (S206). Specifically, the selection means 22 refers to whether the first communication module 50 and the second communication module 60 are connectable or not. The selection means 22 selects the first network 30 or the second network 40 based on the monitoring result of the monitoring means 24 (S207). Specifically, as described above, when the monitoring means 24 determines that only the first network 30 is connected to the first communication module 50, the selection means 22 selects the first network 30. Also, as described above, when the monitoring means 24 determines that only the second network 40 is connected to the second communication module 60, the selection means 22 selects the second network 40. In addition, when the monitoring means 24 determines that the first network 30 and the second network 40 are connected to the first communication module 50 and the second communication module 60, respectively, the selection means 22 selects the first network 30 or the second network 40 based on the identification information or the first priority and the second priority, similar to the communication system 1.

[0040] As described above, the communication device 20 in the communication system 2 includes a monitoring means 24 that monitors both the connection state between the first network 30 and the first communication module 50 and the connection state between the second network 40 and the second communication module 60. The selection means 22 selects the first network 30 or the second network 40 based on the monitoring result of the monitoring means 24. This allows the communication device 20 to transmit information related to the communication information using a network that can communicate with the communication module among the multiple networks. As a result, the communication system 2 allows contacting the user more reliably.

[0041] Furthermore, the communication device 20 in the communication system 2 includes a receiving means 21, a selecting means 22, and a transmitting means 23, similar to the communication device 20 in the communication system 1, and therefore can easily contact the user.

[0042] <Third embodiment> A communication system 3 in the third embodiment will be described with reference to Fig. 5 and Fig. 6. Fig. 5 is a block diagram showing a configuration example of the communication system 3. Fig. 6 is a sequence diagram showing an operation example of the communication system 3. The communication system 3 includes a communication device 20, a first network 30, a second network 40, a first communication module 50, and a second communication module 60. The communication system 3 differs from the communication system 1 in that the communication device 20 further includes a storage means 25.

[0043] The storage means 25 stores a correspondence relationship in which either a first setting to be notified to one of the networks or a second setting to be notified to both networks is associated with the user's identification information. The selection means 22 refers to the correspondence relationship and identifies the setting that corresponds to the user's identification information included in the communication information received by the reception means 21. Note that the reference here may mean that the selection means 22 accesses the storage means 25 to obtain data indicating the correspondence relationship, or may mean that the storage means 25 outputs data indicating the correspondence relationship to the selection means 22. Selection methodWhen the selection means 22 identifies the first setting, it selects only one of the first network 30 and the second network 40. When the selection means 22 identifies the second setting, it selects both the first network 30 and the second network 40.

[0044] The operation of the communication system 3 will be described with reference to Fig. 6. The processes of S101 to S104 and S106 to 110 in the communication system 3 are similar to those of S101 to S104 and S106 to 110 in the communication system 1 shown in Fig. 2, and therefore description thereof will be omitted.

[0045] In the communication system 3, the selection means 22 refers to a correspondence relationship stored in the storage means 24, in which either the first setting or the second setting is associated with the identification information of the user (S301). The selection means 22 identifies a setting corresponding to the identification information (S302). The selection means 22 selects the first network 30 to which the first communication module 50 can be connected or the second network 40 to which the second communication module 60 can be connected based on the identified setting (S303). Specifically, when the selection means 22 determines that the first setting is set for the user, it selects only the first network 30 or the second network 40 based on the identification information, similar to the process of S104. Moreover, when the selection means 22 identifies the second setting, it selects both the first network 30 and the second network 40.

[0046] As described above, in the communication system 3, when a first setting is associated with a user, only one of the first network 30 and the second network 40 is selected, and when a second setting is associated with a user, both the first network 30 and the second network 40 are selected.

[0047] As a result, depending on whether the first setting or the second setting is set for the user, it is possible to switch between transmitting information relating to communication information to only one of the first communication module 50 and the second communication module 60, or transmitting information relating to communication information to both the first communication module 50 and the second communication module 60. As a result, while allowing for easy communication by making reception via one module the rule, it is also possible to flexibly accommodate special users who wish to receive via multiple modules.

[0048] Furthermore, the communication device 20 in the communication system 3 includes a receiving means 21, a selecting means 22, and a transmitting means 23, similar to the communication device 20 in the communication system 1, and therefore can easily contact the user.

[0049] Next, a communication system 3A which is a modified example of the communication system 3 will be described. Fig. 7 shows the configuration of the communication system 3A. Like the communication system 3, the communication system 3A includes a first network 30, a second network 40, a first communication module 50, and a second communication module 60. The communication system 3A differs from the communication system 3 in that the communication device 20 further includes a location information management means 26 and a setting determination means 27.

[0050] The location information management means 26 manages first location information indicating the location of the first communication module 50 and second location information indicating the location of the second communication module 60. Specifically, the first communication module 50 and the second communication module 60 have positioning means such as GNSS (Global Navigation Satellite System) and GPS (Global Positioning System) capable of acquiring their own location information. Each of the first communication module 50 and the second communication module 60 notifies the location information management means 26 of the first location information and the second location information by communicating with the communication device 20.

[0051] In addition, the setting determination means 27 determines the distance between the first communication module 50 and the second communication module 60 based on the first location information and the second location information, and determines whether to apply the first setting or the second setting to the user depending on the distance between the first communication module 50 and the second communication module 60.

[0052] For example, if the distance between the first communication module 50 and the second communication module 60 is short, it is assumed that the user has both the first communication module 50 and the second communication module 60. Therefore, in order to avoid cumbersome operations by the user, it is preferable to transmit information related to communication information to only one of the first communication module 50 and the second communication module 60. Therefore, when the distance between the first communication module 50 and the second communication module 60 is shorter than a threshold value, the setting determination means 27 sets the first setting for the user of the first communication module 50 and the second communication module 60.

[0053] Also, if the distance between the first communication module 50 and the second communication module 60 is long, it is assumed that the user does not have either the first communication module 50 or the second communication module 60. Therefore, in order to reliably contact the user, it is preferable to transmit information regarding communication information to both the first communication module 50 and the second communication module 60. Therefore, when the distance between the first communication module 50 and the second communication module 60 is longer than a threshold, the setting determination means 27 sets the second setting for the users of the first communication module 50 and the second communication module 60. With this configuration, in the communication system 3A, reception by one module is the rule, allowing for easy contact, while also being able to flexibly respond to special situations in which reception by multiple modules is deemed preferable. <Fourth embodiment> A communication device 20 in the fourth embodiment will be described with reference to Fig. 8 and Fig. 9. As shown in Fig. 8, the communication device 20 includes a receiving means 21, a selecting means 22, and a transmitting means 23. The communication device 20 may further include components, functions, and connections similar to those of the communication device 20 in the above-described communication systems 1, 2, 3, and 3A.

[0054] The receiving means 21 receives communication information including the identification information of a destination user from a first terminal (not shown). The receiving means 21 may have the same functions and connection relationships as the receiving means 21 in the above-mentioned communication systems 1, 2, 3, and 3A.

[0055] The selection means 22 selects, based on the identification information, either a first network to which a first communication module associated with the user can be connected or a second network different from the first network to which a second communication module associated with the user can be connected. The selection means 22 may have the same functions and connection relationships as the selection means 22 in the above-mentioned communication systems 1, 2, 3, and 3A.

[0056] The transmitting means 23 transmits information related to the communication information to a communication module connectable to the selected network out of the first communication module and the second communication module, via the network selected by the selecting means 22. The transmitting means 23 may have the same functions and connection relationships as the transmitting means 23 in the above-mentioned communication systems 1, 2, 3, and 3A.

[0057] Next, the operation of the communication device 20 will be described with reference to FIG.

[0058] The receiving means 21 receives communication information (S401). The selecting means 22 selects a first network to which the first communication module can be connected or a second network to which the second communication module can be connected (S402). The transmitting means 23 transmits information related to the communication information to the communication module that can be connected to the selected network (S403).

[0059] As described above, the communication device 20 includes a receiving means 21, a selecting means 22, and a transmitting means 23. The receiving means 21 receives communication information including identification information of a destination user from a first terminal. The selecting means 22 selects, based on the identification information, either a first network to which a first communication module associated with the user can be connected or a second network different from the first network to which a second communication module associated with the user can be connected. The transmitting means 23 transmits information related to the communication information to the communication module that can be connected to the network selected by the selecting means 22, out of the first communication module and the second communication module, via the network selected by the selecting means 22.

[0060] As described above, the communication device 20 selects one of the first and second networks selected by the selection means 22, and transmits information related to the communication information via a communication module connectable to the selected network. Therefore, even if the user has multiple communication modules connectable to different networks, it is possible to select at least one communication module and transmit information related to the communication information. In this case, the information related to the communication information is received by a selected one of the multiple communication modules owned by the user, so that the user can easily grasp the information related to the communication information. In this way, the communication device 20 makes it possible to easily contact the user. In addition, the communication device 20 enables easy contact by making reception by one module the rule, while also being able to flexibly respond to special situations in which reception by multiple modules is deemed preferable.

[0061] Although the present invention has been described above with reference to the embodiment, the present invention is not limited to the above embodiment. Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
