DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the present invention is not limited to this embodiment, and if there are multiple embodiments, the present invention may be configured by combining each embodiment. Further, in the following embodiments, the same parts are given the same reference numerals and redundant explanations will be omitted.

First, before explaining the details of the present invention, an outline of the present invention will be explained. A wireless communication system according to the present invention includes a plurality of wireless devices. The plurality of radios perform group communication. Group communication is started, for example, when the user presses a PTT (Push to Talk) button, and ends when the user releases the PTT button. In group communication, one of the plurality of radios transmits an audio signal, and each of the other radios receives the audio signal. In this case, if there is another wireless device nearby that is performing the same group communication, the user can hear the audio without outputting the audio from the own wireless device. Therefore, in this embodiment, when the user is within a short distance where the user can hear the audio output from another wireless device, the output of audio from the own wireless device is stopped.

The configuration of a wireless communication system according to an embodiment of the present invention will be described using FIG. 1 and FIG. 2. FIG. 1 and FIG. 2 are diagrams showing the configuration of a wireless communication system according to an embodiment of the present invention.

As shown in FIG. 1, the wireless communication system 1 includes a first wireless device 10a, a second wireless device 10b, a third wireless device 10c, a fourth wireless device 10d, a fifth wireless device 10e, and a communication control device. 20. The first radio 10a, the second radio 10b, the third radio 10c, the fourth radio 10d, and the fifth radio 10e are, for example, commercial radios. The communication control device 20 is, for example, a repeater provided in a base station device (not shown). The first radio device 10a to the fifth radio device 10e may be collectively referred to as the radio device 10. The number of wireless devices included in the wireless communication system 1 does not limit the present invention. The wireless communication system 1 is, for example, a commercial wireless communication system.

In the wireless communication system 1, the user U1 sets a group ID (hereinafter referred to as GID) for identifying a group in group communication to "1" for the second wireless device 10b. Therefore, the second radio device 10b performs a standby process for communication (call) with "GID=1" as the destination. The standby process is the above-described call standby state.

The second radio device 10b determines whether or not another radio device 10 exists within a predetermined range R1 (for example, 3 m). The predetermined range R1 is a range in which it is assumed that the user U1 can hear the audio output from the radio device 10 within the range. The second radio device 10b determines whether another radio device 10 exists within a predetermined range R1, for example, by short-range wireless communication. For example, Bluetooth (registered trademark) can be used as the short-range wireless communication. In the example shown in FIG. 1, the third radio device 10c and the fourth radio device 10d exist within a predetermined range R1. The first radio device 10a and the fifth radio device 10e do not exist within the predetermined range R1. In this case, the user U1 can listen to the audio output from the third radio device 10c and the fourth radio device 10d. On the other hand, the voices output from the first radio device 10a and the fifth radio device 10e cannot be heard.

The second radio device 10b determines the GID of the other radio device 10 when determining that the other radio device 10 exists within the predetermined range R1. Specifically, the second radio device 10b determines whether the same GID of “GID=1” as the second radio device 10b is set for the third radio device 10c and the fourth radio device 10d. Determine. The second radio device 10b determines the GID of each of the third radio device 10c and the fourth radio device 10d by, for example, performing short-range wireless communication between the third radio device 10c and the fourth radio device 10d. In the example shown in FIG. 1, the third radio device 10c is set, for example, to perform standby processing with "GID=1". On the other hand, the fourth radio device 10d is set, for example, to perform standby processing with "GID=2".

The second radio device 10b stops the standby process with “GID=1” because the third radio device 10c, which is set to perform the standby process with “GID=1”, exists within the predetermined range R1.

A method for the user U1 to listen to the audio of the group communication with "GID=1" will be described using FIG. 2.

The first wireless device 10a is set to perform standby processing with "GID=1". User U2 is a user who operates the first radio device 10a.

First, the user U2 presses the PTT button of the first wireless device 10a. Thereby, the first radio device 10a transmits group communication with “GID=1” as the destination to the communication control device 20 by long-distance wireless communication. The long-distance wireless communication is, for example, business wireless.

The communication control device 20 broadcasts the group communication received from the first radio device 10a to the third radio device 10c.

The third radio device 10c receives group communication from the communication control device 20. The third radio device 10c outputs audio corresponding to the audio signal included in the group communication from the speaker.

User U1 listens to the audio output from the third radio device 10c. Thereby, the user U1 can listen to the audio of the group communication.

The first antenna 31 receives various wireless signals. The first antenna 31 receives various wireless signals from the communication control device 20, for example. The first antenna 31 outputs the received radio signal to the radio signal receiving section 41.

The second antenna 32 receives a GPS (Global Positioning System) signal. The second antenna 32 outputs the received GPS signal to the own radio device position information acquisition section 421.

Each section of the radio 10 is configured such that a program (for example, a program according to the present invention) stored in a storage section (not shown) is stored in a RAM (Random Access Memory) or the like by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like. This is achieved by executing this as a work area.

The wireless signal receiving section 41 receives a wireless signal via the first antenna 31. The radio signal receiving section 41 outputs the audio signal included in the received radio signal to the audio presentation section 44 . Furthermore, when the radio signal receiving unit 41 does not receive a radio signal from the first antenna 31, it enters a standby state waiting for detection of a received signal, that is, a state in which it performs a standby process. If the process of stopping the wireless signal is not executed by the reception control unit 43, which will be described later, the wireless signal reception unit 41 consumes power regardless of the presence or absence of the received signal.

The information acquisition unit 42 acquires various types of information. The information acquisition section 42 includes an own radio device position information acquisition section 421, an other radio device information acquisition section 422, and a distance calculation section 423.

The own radio location information acquisition unit 421 receives a GPS signal via the second antenna 32. The own radio device position information acquisition unit 421 obtains the location information of the radio device 10 based on the GPS signal. The self-radio device position information acquisition unit 421 acquires, for example, the place name and address of the current location as the position information. The self-radio device position information acquisition unit 421 acquires, for example, coordinate information on a map specified by longitude and latitude as position information. The own radio device position information acquisition unit 421 outputs the acquired position information of the radio device 10 to the distance calculation unit 423.

The other radio device information acquisition unit 422 obtains various information from other radio devices different from the radio device 10. The other wireless device information acquisition unit 422 acquires various information set in the other wireless device, for example, by performing short-range wireless communication such as Bluetooth with the other wireless device. The other radio device information acquisition unit 422 obtains, for example, position information of other radio devices. Other radio equipment information acquisition section 422 outputs the acquired position information of other radio equipment to reception control section 43 .

The distance calculation unit 423 calculates the distance between the radio device 10 and another radio device. The distance calculation unit 423 calculates the location of the radio based on the location information of the own radio received from the own radio location information acquisition unit 421 and the location information of other radios received from the other radio equipment information acquisition unit 422, for example. Calculate the distance between 10 and other radios. The distance calculation unit 423 calculates the distance between the radio device 10 and another radio device by calculating the difference in coordinates between the radio device 10 and the other radio device on the map specified by longitude and latitude, for example. calculate. Distance calculation section 423 outputs distance information regarding the distance between radio device 10 and another radio device to reception control section 43.

The reception control section 43 controls the radio signal reception section 41. The reception control section 43 controls the radio signal reception section 41 to start receiving the radio signal or stop receiving the radio signal. The reception control section 43 controls the radio signal reception section 41 based on the positional relationship between the radio device 10 and other radio devices. The reception control unit 43 controls the wireless signal reception unit 41 based on distance information received from the distance calculation unit 423, for example. For example, when the distance between the radio device 10 and another radio device is less than or equal to a predetermined distance (for example, 3 m), the reception control section 43 controls the radio signal reception section 41 to receive the radio signal. Stop receiving. As described above, the predetermined distance is the distance at which the user U is assumed to be able to hear the audio output from another wireless device. That is, if the distance between the radio device 10 and another radio device is less than or equal to a predetermined distance, the reception control unit 43 stops receiving the radio signal and thereby stops outputting the audio. Specifically, when the distance between the radio device 10 and another radio device is less than or equal to a predetermined distance, the reception control section 43 stops the processing of the radio signal reception section 41 to transmit the audio signal to the audio presentation section 44. output and stop receiving wireless signals. For example, if the distance between the radio device 10 and another radio device exceeds a predetermined distance after stopping the reception of the radio signal, the reception control section 43 transmits the radio signal to the radio signal reception section 41. Receive the signal and resume audio output.

The reception control unit 43 may cut off the power to the wireless signal reception unit 41 as a process for stopping reception of the wireless signal. If the wireless signal reception unit 41 is not stopping the reception of the wireless signal and cannot detect the wireless signal, the wireless signal receiving unit 41 continues the standby process of detecting the wireless signal. Furthermore, when the wireless signal reception is not stopped and a wireless signal is detected, the wireless signal receiving section 41 outputs the audio signal included in the received wireless signal to the audio presentation section 44 .

The audio presentation unit 44 receives audio signals from the wireless signal receiving unit 41. The audio presenting unit 44 performs decoding processing on the audio signal received from the wireless signal receiving unit 41. The audio presentation unit 44 outputs the decoded audio signal from a speaker (not shown) and provides it to the user U.

[Processing of radio device according to first embodiment]
The processing of the wireless device according to the first embodiment of the present invention will be described using FIG. 4. FIG. 4 is a flowchart showing an example of the process flow of the wireless device according to the first embodiment of the present invention.

First, the radio device 10 acquires position information of its own radio device (step S101). Specifically, the own radio device position information acquisition unit 421 obtains the location information of the radio device 10 based on the GPS signal. Then, the process advances to step S102.

The radio device 10 acquires position information of other radio devices (step S102). Specifically, the other wireless device information acquisition unit 422 uses short-range wireless communication to acquire the position information that the other wireless device has acquired based on the GPS signal from the other wireless device. Then, the process advances to step S103.

The position information of other radios acquired by the other radio equipment information acquisition unit 422 will be explained using FIG. 5. FIG. 5 is a diagram for explaining position information of other wireless devices.

As shown in FIG. 5, the location information 100 acquired by the other wireless device information acquisition unit 422 is associated with a wireless device ID for identifying another wireless device and a position. In the example of location information 100, No. Radio No. 1 is at point A, No. The second radio is at point B, No. Radio No. 3 is at point C, No. Radio No. 4 is at point D, No. Radio No. 5 is located at point E.

Referring again to FIG. The radio device 10 calculates the distance between the radio device 10 and another radio device (step S103). Specifically, the distance calculation unit 423 calculates the distance between the radio device 10 and the other radio device based on the location information of the radio device 10 and the location information of the other radio device. Then, the process advances to step S104.

The distance between the radio device 10 and another radio device will be explained using FIG. 6. FIG. 6 is a diagram for explaining the distance between the radio device 10 and other radio devices.

As shown in FIG. 6, the distance information 200 calculated by the distance calculation unit 423 has a wireless device ID and a distance associated with each other. In the example of distance information 200, No. The distance between No. 1 and No. 1 is 10 m. The distance between No. 2 and No. 2 radio is 5 m. The distance between No. 3 and No. 3 is 20 m. The distance between No. 4 and No. 4 is 5 m. The distance between No. 5 and the radio device is 15 m.

Referring again to FIG. The radio device 10 determines whether there is another radio device within a predetermined distance (step S104). Specifically, the reception control unit 43 determines whether or not there is another radio device within a predetermined distance based on the calculation result of the distance calculation unit 423. If it is determined that there is a wireless device within the predetermined distance (Yes in step S104), the process advances to step S105. If it is determined that there is no wireless device within the predetermined distance (No in step S104), the process advances to step S107.

If the determination in step S104 is Yes, the radio device 10 stops receiving the wireless signal and stops outputting audio (step S105). Specifically, the reception control section 43 controls the radio signal reception section 41 to stop receiving radio signals. Then, the process advances to step S101. Therefore, in step S104, the stoppage of reception of wireless signals continues until no wireless devices within a predetermined distance can be confirmed.

If the determination in step S104 is No, the radio device 10 receives the radio signal and outputs audio. Specifically, the reception control section 43 controls the radio signal reception section 41 to start receiving the radio signal (step S106), and receives the radio signal (step S107). Then, the process advances to step S108.

The radio device 10 determines whether the communication has ended (step S108). Specifically, the reception control unit 43 determines whether the communication has ended by determining whether a wireless signal is input to the wireless signal receiving unit 41. If it is determined that the communication has ended (Yes in step S108), the process in FIG. 4 ends. If it is determined that the communication has not ended (No in step S108), the process advances to step S101. Therefore, reception of wireless signals is continued until a wireless device within a predetermined distance is confirmed in step S104.

As described above, in this embodiment, if another radio device exists within a predetermined distance, reception of radio signals by the own radio device can be stopped. In this case, the user of the own wireless device can listen to audio output from other wireless devices existing within a predetermined distance. Thereby, when another radio device exists within a predetermined distance, the own radio device does not need to perform standby processing for communication, so power consumption can be reduced.

[Configuration of radio device according to second embodiment]
The configuration of a wireless device according to a second embodiment of the present invention will be described using FIG. 7. FIG. 7 is a block diagram showing an example of the configuration of a radio device according to the second embodiment of the present invention.

A radio device 10A according to the second embodiment differs from the radio device 10 illustrated in FIG. 3 in that it includes a storage section 45.

The storage unit 45 stores various information. The storage unit 45 stores, for example, various types of information related to group communication set in the radio device 10A. The storage unit 45 stores, for example, GID information regarding the group communication GID set in the radio device 10A. The storage unit 45 is a data readable/writable storage device such as a DRAM (Dynamic Random Access Memory), an SRAM (Static Random Access Memory), a flash memory, or a hard disk.

The radio signal receiving unit 41A receives, via the first antenna 31, a radio signal including an audio signal and GID information (also referred to as destination group ID) of another radio device that transmitted the audio signal. The wireless signal receiving section 41A outputs a wireless signal including the audio signal and the GID to the audio presentation section 44A.

The other radio device information acquisition unit 422A obtains, for example, GID information regarding the GID set in the other radio device from the other radio device. The other radio device information acquisition unit 422A outputs the acquired GID information of the other radio device to the reception control unit 43.

The reception control unit 43A determines whether the GID information received from the other radio device information acquisition unit 422A and the distance information received from the distance calculation unit 423 satisfy a predetermined condition. Specifically, the reception control unit 43A uses the GID information of the other radio device received from the other radio device information acquisition unit 422A and the GID information of the radio device 10A stored in the storage unit 45 to It is determined whether the GID of the wireless device 10A matches the GID of the wireless device 10A. Then, when the GIDs of the radio device 10A and the other radio device match and the distance between the radio device 10A and the other radio device is less than or equal to a predetermined distance, the reception control unit 43A receives the radio signal. The receiver 41A is controlled to stop receiving wireless signals. When the distance between the radio device 10A and another radio device exceeds a predetermined distance, or when the GIDs do not match, the reception control section 43A controls the radio signal reception section 41A to receive the radio signal.

The audio presentation unit 44A receives the audio signal and the GID information of the other wireless device that transmitted the audio signal from the wireless signal receiving unit 41A. Based on the GID information received from the radio signal receiving unit 41A and the GID information of the radio 10A stored in the storage unit 45, the audio presentation unit 44A identifies the other radio that transmitted the audio signal and the radio 10A. It is determined whether the GID and the GID match. The audio presentation unit 44A decodes the audio signal and provides it to the user U when the GID of the other wireless device that transmitted the audio signal and the wireless device 10A match.

[Processing of radio device according to second embodiment]
The processing of the wireless device according to the second embodiment of the present invention will be described using FIG. 8. FIG. 8 is a flowchart showing an example of the process flow of the wireless device according to the second embodiment of the present invention.

Step S201 is the same process as step S101 in FIG. 4, so a description thereof will be omitted.

The radio 10A acquires the position information and GID of other radios (step S202). Specifically, the other radio device information acquisition unit 422A uses short-range wireless communication to transmit the position information acquired by the other radio device based on the GPS signal and the GID set in the other radio device to the other radio device. Get from. Then, the process advances to step S203.

The position information and GID of other radios acquired by the other radio equipment information acquisition unit 422A will be explained using FIG. 9. FIG. 9 is a diagram for explaining position information and GID of other wireless devices.

As shown in FIG. 9, the location information 100A acquired by the other wireless device information acquisition unit 422A is associated with a wireless device ID for identifying another wireless device, a GID, and a position. In the example of position information 100A, No. Radio device 1 has a GID of "2" and is located at point A. No. Radio device No. 2 has a GID of "4" and is located at point B. No. Radio device No. 3 has a GID of "1" and is located at point C. No. Radio device No. 4 has a GID of "2" and is located at point D. No. Radio device No. 5 has a GID of "1" and is located at point D.

Referring again to FIG. The radio device 10A calculates the distance between the radio device 10A and another radio device (step S203). Specifically, the distance calculation unit 423 calculates the distance between the radio device 10 and the other radio device based on the location information of the radio device 10 and the location information of the other radio device. In step S203, the distance calculation unit 423 calculates the distance to the wireless device of each group ID. Then, the process advances to step S204.

The distance between the radio device 10A and another radio device will be explained using FIG. 10. FIG. 10 is a diagram for explaining the distance between the radio device 10A and other radio devices.

As shown in FIG. 10, the distance information 200A calculated by the distance calculation unit 423 is associated with a radio ID, a GID, and a distance. In the example of distance information 200, No. The distance between No. 1 and No. 1 is 10 m. The distance between No. 2 and No. 2 radio is 5 m. The distance between No. 3 and No. 3 is 20 m. The distance between No. 4 and No. 4 is 5 m. The distance between No. 5 and the radio device is 15 m.

Referring again to FIG. The radio device 10A determines whether there is another radio device that satisfies a predetermined condition (step S204). Specifically, the reception control section 43 determines whether there is another radio device whose GID is the same as that of the radio device 10A and which is less than a predetermined distance based on the calculation result of the distance calculation section 423. If it is determined that there is a radio that satisfies the predetermined condition (Yes in step S204), the process advances to step S205. If it is determined that there is no radio device that satisfies the predetermined conditions (No in step S204), the process advances to step S206.

The processes in steps S205 to S208 are the same as those in steps S105 to S108 in FIG. 4, respectively, so a description thereof will be omitted.

As described above, in this embodiment, if the same GID as the own radio is set and there is another radio within a predetermined distance, reception of radio signals by the own radio can be stopped. In this case, the user of the own wireless device can listen to audio output from other wireless devices existing within a predetermined distance. As a result, when another radio set with the same GID is present within a predetermined distance, the own radio does not need to perform standby processing for communication, so power consumption can be reduced.

[Configuration of radio device according to third embodiment]
The configuration of a radio device according to a third embodiment of the present invention will be described using FIG. 11. FIG. 11 is a block diagram showing an example of the configuration of a radio device according to the third embodiment of the present invention.

The radio device 10B according to the third embodiment differs from the radio device 10 shown in FIG. There is.

The presentation control unit 46 controls the audio presentation unit 44B. The presentation control unit 46 controls the audio presentation unit 44B to start outputting audio or stop outputting audio. That is, in the third embodiment, the output of the audio is directly stopped instead of stopping the reception of the wireless signal and stopping the audio. The presentation control section 46 controls the audio presentation section 44B based on the positional relationship between the radio device 10B and other radio devices. The presentation control unit 46 controls the audio presentation unit 44B based on the distance information received from the distance calculation unit 423, for example. For example, when the distance between the radio device 10B and another radio device is less than or equal to a predetermined distance, the presentation control section 46 controls the audio presentation section 44B to stop outputting the audio. Therefore, although the audio presentation section 44B does not output audio, it receives an audio signal from the wireless signal reception section 41A. When the audio presentation unit 44B is receiving an audio signal from the wireless signal receiving unit 41A while the audio output is stopped, the audio presentation unit 44B transmits audio reception information indicating that the audio signal is being received to the presentation control unit 46. Output. Furthermore, if the distance between the radio device 10B and another radio device exceeds a predetermined distance after stopping the output of the audio signal, the presentation control section 46 controls the audio presentation section 44B to output the audio signal. resume.

Further, the presentation control unit 46 controls the information presentation unit 47. The presentation control section 46 controls the information presentation section 47 to present various types of information to the user. The information presentation unit 47 is, for example, a display including an indicator provided in the radio device 10B, a liquid crystal display (LCD), an organic electro-luminescence (EL) display, or the like. When the presentation control section 46 receives the audio reception signal from the audio presentation section 44B, the presentation control section 46 informs the information presentation section that although no audio is being output to the user U, the radio device 10B is receiving a wireless signal. 47 is controlled and presented. For example, if the information presentation unit 47 is an indicator, the presentation control unit 46 lights up the indicator when receiving the audio reception signal. For example, when the information presentation section 47 is a display, the presentation control section 46 may display text such as "receiving wireless signal" when receiving an audio signal.

Furthermore, when the information presentation section 47 is a display, the presentation control section 46 may display the direction in which another radio device outputting audio is located. In this case, the presentation control unit 46 may display the distance in addition to the direction of the other wireless device.

[Modification of the fourth embodiment]
Next, a modification of the radio device 10C according to the fourth embodiment will be described.

The other radio device information acquisition unit 422A of the radio device 10C illustrated in FIG. 6 may acquire various types of information about other radio devices in addition to the GID. Specifically, the other radio device information acquisition unit 422A obtains location information regarding other radio devices, volume information, strength information indicating the strength of radio waves, remaining capacity information indicating the remaining battery level of the radio device, and a method indicating the playback method. Information etc. may also be acquired. The other radio device information acquisition unit 422A outputs various types of acquired information to the presentation control unit 46A.

The location information includes, for example, information regarding whether another wireless device is located outside or inside a building. The position information also includes information regarding whether there are any obstacles around other radios that may block the sound. In other words, the location information includes information regarding the ease of audibility of the audio when another wireless device produces the audio at that location.

The volume information includes information regarding the volume level set on the radio. For example, the volume information may be a specific numerical value, or may be information classified according to the numerical value, such as high, medium, or low.

The strength information includes information regarding the radio field strength of the wireless device. For example, the strength information may be a specific numerical value, or may be information such as good or bad classified according to the numerical value.

The remaining amount information includes information regarding the remaining amount of the battery that drives the radio. For example, the remaining amount information may be a percentage of full charge, or may be the remaining driving time of the radio.

The method information includes information regarding a method for reproducing audio in the wireless device. For example, the method information includes information such as whether the sound is output directly from the radio, or whether the sound is output by an external device for listening to the sound, such as a headset connected to the radio.

The presentation control section 46A controls the audio presentation section 44C based on various information received from the other radio device information acquisition section 422A. The presentation control unit 46A, for example, compares various types of information received from the other radio device information acquisition unit 422A with various types of information set in the radio device 10C, and controls the audio presentation unit 44C according to the comparison result. .

For example, if the position information of the other radio device includes information that there is an obstacle blocking the sound around the other radio device, the presentation control section 46A controls the audio presentation section 44C to display the sound. Output.

For example, based on the audio information of the other radio, the presentation control unit 46A controls the audio presentation unit 44C to stop outputting audio if the volume set in the other radio is higher than that of the radio 10C. For example, the presentation control unit 46A controls the audio presentation unit 44C to output audio if the volume set in the other radio device is lower than that of the radio device 10C.

For example, the presentation control unit 46A controls the audio presentation unit 44C to stop outputting audio if the radio field strength of the other wireless device is better than that of the wireless device 10C, based on the intensity information of the other wireless device. For example, if the radio field strength of another wireless device is poorer than that of the wireless device 10C, the presentation control section 46A controls the audio presentation section 44C to output audio.

For example, the presentation control unit 46A controls the audio presentation unit 44C to display audio when the remaining battery level of the other wireless unit is greater than the remaining battery level of the wireless unit 10C, based on the strength information of the other wireless unit. Stop outputting. The presentation control unit 46A controls the audio presentation unit 44C to output audio, for example, when the remaining battery level of the other wireless device is less than the remaining battery level of the wireless device 10C.

For example, the presentation control unit 46A controls the audio presentation unit 44C to output audio based on the method information when an external device such as a headset is connected to another wireless device.

As described above, in this modification, it is possible to stop the audio output of the own wireless device according to various conditions. In this case, the user of the own wireless device can listen to audio output from other wireless devices existing within a predetermined distance. As a result, when another radio set with the same GID is present within a predetermined distance, the own radio does not need to perform standby processing for communication, so power consumption can be reduced.
