When there is no need to distinguish between the communication device 10-1 and the communication device 10-2, they may be collectively referred to as the communication device 10. The first base station device 12-1 and the second base station device 12-2 are base stations located in different locations. Although the description will be given as a station device, it may be a base station device located in one location.

[0014] The communication device 10-1 and the communication device 10-2 are configured to use a first communication method and a second communication method different from the first communication method. The first communication method is, for example, a narrowband communication method. The second communication method is, for example, broadband communication.

[0015] Next, an outline of the communication process of the communication system 1 will be described. First, the communication device 10-1 , the first base station device 12-1 receives the user's A first audio signal based on audio and a first synchronization signal are transmitted (step S1). The communication method is, for example, narrowband communication. Narrowband communication is, for example, Wi-Fi (registered trademark), Bluetooth, or LTE (Long Term Evolution) Subsequently, the first base station device 12-1 receives the following from the communication device 10-1: The first audio signal and the first synchronization signal are transmitted to the communication device 10-2 in the first communication method. (Step S2). Next, the communication device 10-2 generates a voice signal based on the voice of the user of the communication device 10-2. a second voice signal based on the second voice signal and a second synchronization signal, and a second voice signal based on the second voice signal and a second synchronization ... First reception sensitivity information (first reception sensitivity information) indicating reception sensitivity when the first audio signal and the first synchronization signal are received The first base station device 12-1 transmits the received signal (also called the signal reception sensitivity) to the first base station device 12-1 by the first communication method (step Step S3). The first receiving sensitivity is, for example, RSSI (Received Signal Strength Indicator). r) value, or CRC (Cyclic Redundancy Check) error rate. The station device 12-1 receives the second audio signal, the second synchronization signal, and the second The first communication method is used to transmit the first reception sensitivity information (step S4). In this method, the communication device 10-1 and the communication device 10-2 communicate with each other via the first base station device 12-1. Alternatively, direct communication may be performed without using the

In this case, the first base station device 12-1 receives the second voice signal from the communication device 10-2 and The synchronization signal and the second receiving sensitivity information are transmitted using the second communication method (step S8). In the second communication method, the communication device 10-1 and the communication device 10-2 are the first base station device. Communication may be made directly without going through 12-1.

If it is determined that there is (step S56; No), the process proceeds to step S60.

[0060] If the determination in step S56 is Yes, the communication control unit 40 determines the communication unit as the priority communication unit. The second communication unit 22 is controlled to stop communication when the first communication unit 20 is not communicating.

If it is determined that the process is not to be completed (step S206; No), the process returns to step S200. .

[0121] (Second example) FIG. 22 illustrates a communication control method of a management device according to a second example of the second embodiment. FIG. 22 is a flowchart showing the flow of a communication control method of a management device according to a second example of the second embodiment. It is a chart.

[0122] The communication control method of the management device according to the second example of the second embodiment is a method of controlling communication by giving priority to the first communication method. Group communication is the preferred communication method, and voice communication is the first communication method. When the first reception sensitivity information improves during the supplementary voice communication of the second communication method, This is a method for terminating the voice communication complement of the communication method.

[0123] The process of step S210 is the same as the process of step S200 shown in FIG. 21, so the explanation will be omitted. is omitted.

[0124] Next, the control unit 64 determines whether the first reception sensitivity information is equal to or greater than a second threshold value. For example, the control unit 64 may select all of the first reception sensitivity information items. For example, the control unit 10 may determine whether the first reception sensitivity information is less than a second threshold value. The unit 64 selects a predetermined ratio or number or more of the first reception sensitivity information from the plurality of first reception sensitivity information. It may be determined whether the first reception sensitivity information is equal to or greater than a second threshold value. If it is determined that the second threshold value is equal to or greater than the second threshold value (step S212; Yes), If it is determined that the first reception sensitivity information is less than the second threshold value (step S214), If the answer is YES in step S212, the process proceeds to step S216.

[0125] If the determination in step S212 is Yes, the control unit 64 The base station device 12 complements the voice communication of the first communication method with the voice communication of the second communication method. The instruction to end the process is given (step S214).

[0126] The process of step S216 is the same as the process of step S206 shown in FIG. 21, so the explanation will be omitted. During the processing from step S210 to step S216, the priority communication method is not changed. No changes are made.

[0127] As described above, in the second embodiment, the management device controls the first communication Voice communication in the first communication method can be supplemented with voice communication in the second communication method.
