The wireless communication device 1 is a device capable of wirelessly communicating with each of the wireless device A100, the wireless device B200, the wireless device C101, the wireless device D102, and the wireless device E103. The wireless communication device 1 is, for example, a base station, a repeater, or the like.

The radio A100, the radio B200, the radio C101, the radio D102, and the radio E103 are devices capable of performing wireless communication via the wireless communication device 1. The Unit IDs (hereinafter referred to as UIDs) that identify the radio A100, the radio B200, the radio C101, the radio D102, and the radio E103 are 100, 200, 101, 102, and 103, respectively. .. Each radio device is provided with a means for detecting its own position. The means for detecting the own position is, for example, positioning the own position by a signal from a satellite or the like, but is not limited to this. The means for detecting the own position may be configured by any of the well-known position detection techniques.

A predetermined function is implemented in the radio A100. The predetermined function is, for example, a function of transmitting voice to a short distance of the radio A100. Specific examples of the predetermined functions include a loudspeaker function that louds the sound collected by the microphone and outputs it from the speaker, and a short-range wireless communication function such as Bluetooth (registered trademark). The public address function is also called a PA (Public Address) function. The radio A100 is, for example, an in-vehicle radio, but is not limited to this. The radio A100 is also called a first radio.

The storage unit 500 is a storage medium that can be accessed by the wireless communication device 1. The storage unit 500 is provided in, for example, a base station. That is, when the wireless communication device 1 is a base station, the storage unit 500 may be provided in the wireless communication device 1.

Subsequently, the configuration of the wireless communication device 1 according to the first embodiment will be described with reference to the block diagram of FIG. The wireless communication device 1 according to the first embodiment includes a first receiving unit 10, a second receiving unit 20, an acquisition unit 30, a determination unit 40, and a transmitting unit 50.

The first receiving unit 10 receives a notification of the start of a predetermined function and a notification of the end of the predetermined function from the first radio (radio A100). In addition, the first receiving unit 10 outputs the received start notification of the predetermined function and the end notification of the predetermined function to the determination unit 40.

The second receiving unit 20 receives an individual voice communication (hereinafter, also referred to as Individual Call) call permission request to the second radio from the third radio. Further, the second receiving unit 20 outputs the received Individual Call call permission request to the determination unit 40.

The acquisition unit 30 acquires the distance between the first radio and the second radio. For example, the acquisition unit 30 acquires the distance by calculating the distance between the position of the first radio and the position of the second radio by causing the CPU (Central Processing Unit) or the like to execute the program. do. Further, the acquisition unit 30 outputs the acquired distance to the determination unit 40. The distance may be acquired by the acquisition unit 30 when a distance acquisition request is received from the determination unit 40.

When the determination unit 40 receives the Individual Call call permission request between the time when the notification of the start of the predetermined function is received and the time when the notification of the end of the predetermined function is received, the determination unit 40 refers to the distance received from the acquisition unit 30. do. Then, the determination unit 40 determines whether to disallow or permit the Individual Call call permission request based on whether or not the distance received from the acquisition unit 30 is within a predetermined distance. Specifically, when the distance received from the acquisition unit 30 is within a predetermined distance, the determination unit 40 determines that the Individual Call call permission request is not permitted. Further, when the distance received from the acquisition unit 30 is not within the predetermined distance, the determination unit 40 determines that the individual call call permission request is permitted. The processing of the determination unit 40 can be realized by causing a CPU or the like to execute a program. The determination unit 40 outputs the determination result for the Individual Call call permission request to the transmission unit 50. When the determination unit 40 receives the Individual Call call permission request between the time when the start notification of the predetermined function is received and the time when the end notification is received, the determination unit 40 receives the first radio and the second radio. The distance acquisition request for requesting the acquisition of the distance to the machine may be output to the acquisition unit 30.

The transmission unit 50 receives the determination result from the determination unit 40. Then, the transmission unit 50 transmits a response to the Individual Call call permission request, that is, permission or disapproval, to the third radio.

The third radio cannot make an individual voice communication call to the second radio by receiving a disapproval reply to the Individual Call call permission request. Therefore, the second radio does not reproduce voice by individual voice communication with the third radio.

By providing the above-described configuration, the wireless communication device 1 is a second radio device in which the distance from the first radio device is within a predetermined distance while the first radio device is using a predetermined function. Calls to can be disallowed. This makes it possible to prevent the predetermined function of the first radio from being hindered by the audio reproduction of the second radio.

Subsequently, a specific example of the first embodiment will be described with reference to FIGS. 3, 4A and 4B. In addition, in FIG. 3, FIG. 4A and FIG. 4B, the same process is executed at the same step number. In this example, the loudspeaker function is used as a predetermined function. Further, in this example, the radio C101 is the second radio, and the radio B200 is the third radio.

A specific example of the processing flow of the wireless system 1000 will be described with reference to the sequence diagrams of FIGS. 4A and 4B. First, when the power is turned on, each radio periodically acquires its own position information and transmits the position information and the UID that identifies itself to the wireless communication device 1 (step S101). A specific example of the position information is latitude / longitude information.

Next, the wireless communication device 1 stores the position information and the UID received from each wireless device in the table 501 of the storage unit 500 (step S102). The table 501 is a table that stores the UID of each radio in association with the position information.

At this stage, the loudspeaker function by the radio A100 has not been started. Therefore, when the wireless communication device 1 receives the Individual Call call permission request from the radio B200 to the radio C101 as the call destination (step Sa), the wireless communication device 1 transmits the Individual Call call permission to the radio B200 (step). Sb). As a result, the radio B200 makes an Individual Call call (step Sc), and the wireless communication device 1 relays the Individual Call call to the radio C101 (step Sd). The Individual Call call permission request includes the UID (101) of the call destination radio C101.

Next, the user of the radio A100 presses a loudspeaker button (not shown) of the radio A100 in order to use the loudspeaker function (step S103a). When the loudspeaker button is pressed, the radio A100 transmits a loudspeaker function start notification including its own UID (100) to the wireless communication device 1 (step S103b). That is, the wireless communication device 1 receives the loudspeaker function start notification including the UID of the wireless device A100 from the wireless device A100 by the first receiving unit 10.

Next, the wireless communication device 1 stores the UID (100) included in the loudspeaker function start notification received in step S103b in the table 502 of the storage unit 500 (step S104). The table 502 is a table that stores the UID of the radio that is using the loudspeaker function.

Next, the wireless communication device 1 transmits a loudspeaker function start confirmation to the radio A100 (step S105).

The radio A100 that has received the loudspeaker function start confirmation notifies the user that the loudspeaker function start confirmation has been received, for example, by sounding a beep sound (step S106a). Further, from this point in time, the radio A100 amplifies the sound collected by the microphone and outputs it from the speaker (step S106b). The user of the radio A100 speaks and starts voice transmission by the loudspeaker function (step S106c).

Next, in order to make an Individual Call with the radio C101, the user of the radio B200 presses a PTT (Push to Talk) button (not shown) after designating the UID of the radio C101. When the PTT button is pressed, the radio B200 transmits an Individual Call call permission request including the UID (101) of the call destination radio C101 to the radio communication device 1 (step S107). That is, the wireless communication device 1 receives the Individual Call call permission request including the UID of the call destination radio C101 from the radio B200 by the second receiving unit 20.

Next, since the wireless communication device 1 stores 100 as the UID of the radio that is using the loudspeaker function in the table 502 by the determination unit 40, it is determined that the loudspeaker function is used in the wireless communication device A100. do. Further, the wireless communication device 1 refers to the table 501 by the acquisition unit 30, and refers to the distance between the position of the wireless device A100 (point A) and the position of the wireless device C101 (point C) to which the Individual Call is called. To get. Then, the wireless communication device 1 determines whether or not the distance between the position of the wireless device A100 and the position of the wireless device C101 is within a predetermined distance by the determination unit 40. The predetermined distance in this example is 10 m. In this example, as shown in FIG. 3, the distance between the position of the radio A100 and the position of the radio C101 is within 10 m. Therefore, the wireless communication device 1 determines by the determination unit 40 that the distance between the position of the wireless device A100 and the position of the wireless device C101 is within a predetermined distance. As a result, the wireless communication device 1 determines that the individual call permission request of the radio B200 is not permitted by the determination unit 40 (step S108).

Next, the wireless communication device 1 transmits the Individual Call call disapproval to the radio B200 by the transmission unit 50 (step S109).

When the radio B200 receives the permission to make an Individual Call call, the radio B200 notifies the user to that effect and does not make an Individual Call call (step S110).

When the wireless communication device 1 receives the Individual Call call permission request with the radio E103 as the call destination in step S107, the radio A100 and the radio E103 are combined as shown in FIG. The distance is not within a predetermined distance of 10 m. In this case, the wireless communication device 1 transmits the Individual Call call permission to the radio B200. As a result, the radio B200 that has received the Individual Call call permission calls the Individual Call with the radio E103 as the call destination.

When the user of the radio A100 finishes speaking (step S111a), the loudspeaker button is released (step S111b), and the voice transmission by the loudspeaker function ends (step S111c). When the loudspeaker button is released, the radio A100 transmits a loudspeaker function end notification including the UID of the radio A100 to the wireless communication device 1 (step S111d). That is, the wireless communication device 1 receives the loudspeaker function end notification including the UID of the wireless device A100 from the wireless device A100 by the first receiving unit 10.

When the wireless communication device 1 receives the loudspeaker function end notification, it determines that the loudspeaker function started by the loudspeaker function start confirmation transmitted in step S105 has ended, and is recorded in the table 502 as the UID of the radio in use of the loudspeaker function. Clear 100 (step S112).

According to steps S101 to S112, the individual call is restricted during the individual call call restriction period shown in FIG. 4B. Since steps Sa to Sd in FIG. 4A are not the individual call call restriction period, the individual call is called to the radio C101.

As described above, the wireless communication device 1 according to the first embodiment goes to the second radio device between the time when the start notification of the loudspeaker function is received from the first radio device and the time when the end notification is received. The configuration is such that it is determined whether or not the Individual Call call permission request has been received from the third radio. Further, when the wireless communication device 1 receives the Individual Call call permission request between the time when the loudspeaker function start notification is received and the time when the end notification is received, the wireless communication device 1 receives the first radio and the second radio. It is configured to determine whether or not the distance between and is within a predetermined distance. Further, when the distance between the first radio device and the second radio device is within a predetermined distance, the wireless communication device 1 determines that the individual call call permission request is not permitted, and determines that the individual call call is made. The configuration is such that a response indicating that the permission request is not permitted is transmitted to the third radio. As a result, in the wireless communication device 1 according to the first embodiment, while the loudspeaker function is used in the first radio, the individual voice in the radio within a predetermined distance from the first radio is used. It is possible to suppress and control the reception of communication. Therefore, the wireless communication device 1 can suppress inconvenience in the transmission of the loudspeaker voice by the loudspeaker function of the first radio device.

When the predetermined function is the loudspeaker function, the wireless communication device 1 also receives the volume of the loudspeaker function, and disallows or permits the Individual Call call permission request based on this volume. It may be determined whether or not. In this case, the wireless communication device 1 receives the volume of the loudspeaker function from the first receiver together with the notification of the start of the loudspeaker function by the first receiving unit 10. In addition, the wireless communication device 1 also uses the volume of the loudspeaker function to determine whether the individual call call permission request is disapproved or permitted by the determination unit 40. For example, the wireless communication device 1 may change a predetermined distance based on the volume of the loudspeaker function. Specifically, the value of the predetermined distance may be increased as the volume of the loudspeaker function increases. As a result, it is possible to suppress and control the reception of individual voice communication in the radio in the range corresponding to the volume of the loudspeaker function. Note that the volume-based control of the loudspeaker function can also be applied to other embodiments described below.

Modification Example of Embodiment 1 Subsequently, a modification of Embodiment 1 will be described. The first embodiment is an embodiment for suppressing individual voice communication, but a modification of the first embodiment is for suppressing group voice communication (hereinafter, also referred to as Group Call). Is in the form of.

The wireless system 1000A according to the modified example of the first embodiment includes a wireless communication device 1A, a wireless device A100, a wireless device B200, a wireless device C101, a wireless device D102, a wireless device E103, a storage unit 500, and the like. It has. The configuration of the wireless system 1000A is the same as the configuration of the wireless system 1000 of FIG. 1, and the illustration is omitted.

In this example, it is assumed that 300 is set as the same group ID (hereinafter, also referred to as GID) in the radio B200, the radio C101, and the radio D102. Group Call can be performed between a plurality of radios in which the same GID is set.

Subsequently, the configuration of the wireless communication device 1A will be described. The wireless communication device 1A includes a first receiving unit 10, a second receiving unit 20A, an acquisition unit 30A, a determination unit 40A, and a transmitting unit 50A. The configuration of the wireless communication device 1A is the same as the configuration of the wireless communication device 1 of FIG. 2, and the illustration is omitted.

The second receiving unit 20A receives a Group Call call permission request from the third radio to the radio group composed of the plurality of second radios. Further, the second receiving unit 20A outputs the received Group Call call permission request to the determination unit 40A.

The acquisition unit 30A acquires each distance between the first radio and the plurality of second radios. Further, the acquisition unit 30A outputs each acquired distance to the determination unit 40A.

When the determination unit 40A receives the Group Call call permission request between the time when the notification of the start of the predetermined function is received and the time when the notification of the end of the predetermined function is received, the determination unit 40A obtains each distance received from the acquisition unit 30A. refer. Then, the determination unit 40A determines whether to disallow or permit the Group Call call permission request based on each distance received from the acquisition unit 30A. For example, the determination unit 40A determines that the Group Call call permission request is not permitted when at least one of the distances is within a predetermined distance. The determination unit 40A outputs the determination result for the Group Call call permission request to the transmission unit 50A. The method of determination is not limited to the method described above. For example, the determination unit 40A may determine that the Group Call call permission request is permitted when even one of the distances is not within a predetermined distance.

The transmission unit 50A receives the determination result from the determination unit 40A. Then, the transmission unit 50A transmits a response to the Group Call call permission request, that is, permission or disapproval, to the third radio.

The third radio can make a group voice communication call to a radio group composed of a plurality of second radios by receiving a disapproval reply to the Group Call call permission request. Can not. Therefore, the plurality of second radios do not reproduce voice by group voice communication with the third radio.

Subsequently, a specific example will be described. In this example, if at least one of the distances between the first radio and the plurality of second radios is within a predetermined distance, the Group Call call permission request is not accepted. It will be described as being judged as permission.

The wireless communication device 1A is a group having a GID of 300 by the second receiving unit 20A between the time when the first receiving unit 10 receives the start notification of the loudspeaker function from the radio A100 and the time when the end notification is received. It is assumed that the group call call permission request to the radio B200 is received from the radio B200. In this case, the wireless communication device 1A acquires the distances between the wireless device A100 and the wireless devices C101 and the wireless device D102 that form a group having a GID of 300 by the acquisition unit 30A.

Next, in the wireless communication device 1A, when the determination unit 40A has a distance within a predetermined distance of the distance between the radio A100 and the radio C101 and the distance between the radio A100 and the radio D102. , Group Call Judges that the call permission request is not permitted.

Then, the wireless communication device 1A transmits a response to the disallowed Group Call call permission request to the wireless device B200 by the transmission unit 50A.

As described above, the wireless communication device 1A according to the modified example of the first embodiment has a plurality of wireless communication devices 1A with the first wireless device while the first wireless device is using a predetermined function due to the above-described configuration. Based on each distance to and from the second radio, it is possible to disallow calling group voice communications to a radio group composed of a plurality of second radios. This makes it possible to prevent the predetermined function of the first radio from being hindered by the audio reproduction of the second radio.

Embodiment 2
Subsequently, the second embodiment will be described. The wireless system 1000B according to the second embodiment includes a wireless communication device 1B, a wireless device A100, a wireless device B200, a wireless device C101, a wireless device D102, a wireless device E103, and a storage unit 500B. There is. The configuration of the wireless system 1000B is the same as the configuration of the wireless system 1000 of FIG. 1, and the illustration is omitted.

In this example, it is assumed that the same GID is set in the radio A100, the radio B200, the radio C101, and the radio D102.

Subsequently, the configuration of the wireless communication device 1B will be described. The wireless communication device 1B includes a first receiving unit 10, a second receiving unit 20, an acquiring unit 30B, a determination unit 40B, and a transmitting unit 50. The configuration of the wireless communication device 1B is the same as the configuration of the wireless communication device 1 of FIG. 2, and is not shown.

The acquisition unit 30B acquires the first GID, which is the ID of the group to which the first radio belongs, and the second GID, which is the ID of the group to which the second radio belongs. Further, the acquisition unit 30B outputs the first GID and the second GID to the determination unit 40B.

When the determination unit 40B receives the Individual Call call permission request between the time when the notification of the start of the predetermined function is received and the time when the notification of the end of the predetermined function is received, the first GID and the first GID received from the acquisition unit 30B Refer to the second GID. Then, the determination unit 40B determines whether to disallow or permit the Individual Call call permission request by comparing the first GID and the second GID. Specifically, when the first GID and the second GID match, the determination unit 40B determines that the Individual Call call permission request is not permitted. Further, when the first GID and the second GID do not match, the determination unit 40B determines that the Individual Call call permission request is permitted. The determination unit 40B outputs the determination result for the Individual Call call permission request to the transmission unit 50.

By providing the above-described configuration, the wireless communication device 1B provides an individual call to a second radio device that belongs to the same group as the first radio device while the first radio device uses a predetermined function. Calls can be disallowed. Radios belonging to the same group may be located close to each other. Therefore, by disallowing the calling of Individual Call to the second radio belonging to the same group as the first radio, the predetermined function of the first radio becomes the function of the second radio. It is possible to prevent it from being hindered by audio reproduction.

Subsequently, a specific example of the second embodiment will be described with reference to FIGS. 5, 6A and 6B. In this example, the radio C101 is the second radio and the radio B200 is the third radio.

A specific example of the processing flow of the wireless system 1000B will be described with reference to the sequence diagrams of FIGS. 6A and 6B. First, when the power is turned on, each radio periodically transmits the UID that identifies itself and the GID of the group to which it belongs to the wireless communication device 1B (step S201).

Next, the wireless communication device 1B stores the UID and GID received from each wireless device in the table 503 of the storage unit 500B (step S202). The table 503 associates the UID and GID of each wireless device with each other. It is a table to memorize. In this example, as shown in Table 503 of FIG. 5, the GID of the radio A100, the radio B200, the radio C101, and the radio D102 is stored as 300, and the GID of the radio E103 is stored as 400. ..

Next, the user of the radio A100 presses a loudspeaker button (not shown) of the radio A100 in order to use the loudspeaker function (step S203a). When the loudspeaker button is pressed, the radio A100 transmits a loudspeaker function start notification including its own GID (300) to the wireless communication device 1B (step S203b). That is, the wireless communication device 1B receives the loudspeaker function start notification including the GID of the wireless device A100 from the wireless device A100 by the first receiving unit 10.

Next, the wireless communication device 1B stores the GID (300) included in the loudspeaker function start notification received in step S203b in the table 504 of the storage unit 500B (step S204). The table 504 is a table that stores the GID of the radio that is using the loudspeaker function.

Steps S205 to S207 are the same as steps S105 to S107 in FIG. 4B, and the description thereof will be omitted.

Next, the wireless communication device 1B uses the acquisition unit 30B to refer to the table 504 and acquire 300 stored as the GID of the radio device using the loudspeaker function. Further, the wireless communication device 1B acquires 300 as the GID of the wireless device C101 which is the call destination of the Individual Call call permission request by referring to the table 503 by the acquisition unit 30B. Then, the wireless communication device 1B determines by the determination unit 40B that the GID of the wireless device using the loudspeaker function and the GID of the wireless device C101 which is the call destination of the Individual Call call permission request are the same. As a result, the wireless communication device 1B determines that the individual call call permission request of the wireless device B200 is not permitted by the determination unit 40B (step S208).

Steps S209 to S211 are the same as steps S109 to S111 of FIG. 4B, and description thereof will be omitted.

When the wireless communication device 1B receives the loudspeaker function end notification, it determines that the loudspeaker function started by the loudspeaker function start confirmation transmitted in step S205 has ended, and is recorded in the table 504 as the GID of the radio in use of the loudspeaker function. Clear the 300 (step S212).

In step S207, when the wireless communication device 1B receives the Individual Call call permission request with the radio E103 as the call destination, the GID 300 of the radio in use of the loudspeaker function and the radio E103 It is different from the GID 400. Therefore, the wireless communication device 1B transmits the Individual Call call permission to the wireless device B200. As a result, the radio B200 that has received the Individual Call call permission calls the Individual Call with the radio E103 as the call destination.

As described above, the wireless communication device 1B according to the second embodiment goes to the second radio device between the time when the start notification of the loudspeaker function is received from the first radio device and the time when the end notification is received. The configuration is such that it is determined whether or not the Individual Call call permission request has been received from the third radio. Further, when the wireless communication device 1B receives the Individual Call call permission request between the time when the start notification of the loudspeaker function is received and the time when the end notification is received, the GID and Individual Call which are using the loudspeaker function are issued. It is determined whether or not the GID of the radio of the call destination of the call permission request matches. Further, when the two GIDs match, the wireless communication device 1B determines that the Individual Call call permission request is not permitted, and gives a reply indicating that the Individual Call call permission request is not permitted. It is configured to transmit to the radio of 3. As a result, in the wireless communication device 1B according to the second embodiment, while the loudspeaker function is used in the first wireless device, individual voice communication is received by the wireless devices in the same group as the first wireless device. Can be suppressed and controlled. Therefore, the wireless communication device 1B can suppress inconvenience in the transmission of the loudspeaker voice by the loudspeaker function of the first radio device.

The cases in which the second embodiment is implemented are, for example, the following cases. It is generally assumed that a particular unit, such as a team, has the same GID. The user of the radio A100 wants to perform voice transmission to a member of the team in which the same GID as the radio A100 is set. Further, the user of the radio A100 recognizes that the members of the team are gathered in the range where the loudspeaker voice by the loudspeaker function can be heard. In such a case, in order to reduce the traffic due to the wireless communication, the user of the radio A100 performs voice transmission by the loudspeaker function instead of performing the Group Call by the radio A100.

Further, while the user of the radio A100 is performing voice transmission by the loudspeaker function, the user of the radio B200 intends to make an Individual Call to the radio C101 and transmits an Individual Call call permission request. In this case, since the radio C101 is in the same group as the radio A100 using the loudspeaker function, the radio communication device 1B suppresses and controls the individual call of the radio B200 with respect to the radio C101. As a result, the radio A100 does not use the radio traffic, but can perform voice transmission to the members of the team as if the radio traffic is virtually used by the loudspeaker function.
