Here, with regard to the sound quality, for example, different sound sounds, sound songs, or sound rhythms are set for each of the sound quality “1”, “2”, and “3”. In response, a preset sound quality sounds.
Further, in FIG. 5B, when the importance of the received notification information is high (importance = 1), it rings with “sound quality = 1”, and when the importance is low (importance = 3), “ Rings at “Sound quality = 3”.
For example, a different ringing sound, ringing song, or ringing rhythm is set for each of the sound qualities “1”, “2”, and “3”, and “sound quality = 1” with high importance is “sound quality = low” with low importance. Compared to “3”, a song having a fast tone or a ringing pattern having a fast rhythm is set as the sound quality in advance.
Here, as for the volume, for example, different sound volumes are set for each of the sound qualities “1”, “2”, and “3”, and the volume is set in advance according to the type of the media type in FIG. Therefore, the above-mentioned sound quality sounds.

FIG. 1 shows an example of an operation sequence in the case of transmitting information on simultaneous commands from the control station to the terminal station.
When issuing a command (report) from the command board 1, the report protocol D42 is selected (step S11).
If the selected notification protocol is a simultaneous notification, the importance of the content of the notification (information of the simultaneous notification) is selected (step S12). This importance selection may be set by an operation input from a command board, or may be set as an emergency call such as when the measurement data of another device, for example, a telemeter exceeds a predetermined value.
4 is stored in the memory table of FIG. 4 and information indicating importance is stored in the importance information D43 (step S13). It is transmitted via the device 3 (step S14).

Here, the transmission in step S14 is a simultaneous notification, and each of the terminals 20 receives the simultaneous notification (step S21). Then, the fact that the received data is a simultaneous report is extracted from the high-speed associated channel “FACCH”, and the memory table as shown in FIG. 5 (a) or (b) is referred to (step S22).
As a result of referring to step S22, for example, when the importance level is “high”, “D52: high volume” in FIG. 5A is selected, and the ringing tone (ringing tone) of the telephone 7 is output. (Step S24).
Alternatively, as a result of referring to step S22, for example, when the importance is “high”, “D62: sound quality 1” in FIG. 5B is selected, and the ringing tone (ringing tone) of the telephone 7 is output. (Step S24).
By such an operation, in the case of simultaneous notification, the importance level information is added and transmitted, and the terminal station that has received the information can output the ringing sound with its volume and sound quality varied.

In addition, when a high-priority broadcast message is received, it is important for both sound and vision by turning on the LED provided on the phone or displaying the fact that a high-priority broadcast message has been received on the display screen. A high degree of sensation can be sensed.
For example, as a result of referring to the memory table in step S22, in the case of simultaneous notification with high importance, the LED is blinked together with the sound output of step S24 (step S23).
Then, by taking the transmission / reception part of the telephone 7 (taking a so-called telephone call), it is determined that the simultaneous notification has been heard and the LED is turned off (step S25).
Furthermore, by receiving a broadcast message with high importance and replying that it has been listened to (step S26, step S15), the control station can grasp the terminal station that has listened to the broadcast message. The terminal for listening can be displayed on the display unit of the command board 1 or the like.

Here, regarding transmission / reception with the terminal station 21 via the relay station 30, the part of the control station 10 in the operation sequence of FIG. 1 described above transmits to the terminal station 21 via transmission / reception between the control station 10 and the relay station 30. Transmission / reception will be performed.

Here, the simultaneous command can be, for example, a simultaneous command for each group. This is, for example, grouping by region, fire fighting group or private group.
Further, one terminal station may belong to a plurality of groups, and further, a plurality of groups may be selected and used as a simultaneous command.

As described above, in the broadcast radio system of this example, the control station 10 including the command board 1, the control device 2, and the master station radio device 3, the relay station 30, the slave station radio device 6, and the telephone 7 are used. When the control station 10 includes terminal stations (slave station devices) 20 and 21 and performs broadcast communication (broadcasting) from the control station 10 to the terminal stations 20 and 21, the control station 10 Importance level information is added to each terminal station, and each of the terminal stations 20, 21 variably controls a ringing tone (ringing tone) based on the importance level information for each broadcast communication (each report content).
In addition, by receiving a broadcast message having a high degree of importance and returning the fact that it has been listened to, the control station 10 can grasp which terminal station has listened to the broadcast message.

Therefore, in the broadcast radio system of this example, each terminal station 20, 21, etc. can grasp the content of the report with high importance by receiving sounding, for example, to prevent unheard of important information, The user can be notified of important information.

According to the present invention, the quality and volume of the ringing tone of the answering telephone can be changed according to the importance and urgency of the voice simultaneous command, and the receiver side can clearly grasp the appeal degree of the simultaneous command itself. it can.
For example, in a disaster prevention administrative communication system composed of a control station that issues a voice simultaneous command and a plurality of terminal stations that issue a voice simultaneous command, This is a simultaneous command system with different sound quality.
Further, when receiving a simultaneous command, the ringing volume or sound quality of the telephone can be changed according to the urgency or type of the simultaneous command.
In other words, when the importance level is high, the received sound volume is increased or the received sound quality is changed from the normal sound quality so that the ringing is performed according to the importance level of the report information from the master station device. Can be changed.

As described above in detail, for example, in the conventional disaster prevention administrative wireless communication system, the ringing sound of the telephone at the time of simultaneous voice command is the same regardless of the content of the simultaneous command and the degree of urgency, and a disaster has occurred Even if a highly urgent command is issued at times, the handler on the receiving side does not know that it is an urgent matter until he raises the handset of the receiving phone and listens to the details of the command. The command type shall be set to normal simultaneous and emergency simultaneous, and the control device that receives the simultaneous shall be a system that performs effective disaster prevention administration by changing the volume and sound quality of the ringing sound of the answering telephone according to the type of simultaneous command Can do.
In other words, in the conventional system, since the voice simultaneous command is used for administrative work communication etc. in normal times, even if a highly urgent command is issued when a disaster occurs, It was not known that it was an urgent matter until the telephone receiver was lifted and the contents of the command were heard. However, as in the present invention, the general command and the emergency simultaneous are provided for the types of general commands, It turns out that it is an urgent matter by changing the volume and quality of the ringing sound of the answering telephone according to the type of simultaneous command.
For example, in the case of emergency simultaneous calls, the receiving telephone is called at a louder volume than normal simultaneouss to appeal that it is an important simultaneous command. Or, in the case of emergency simultaneous, the ringing tone has a higher frequency than normal simultaneous and appeals that it is an important simultaneous command.
