  The wireless transceiver 10 receives a transmission signal. The wireless transceiver 10 may be, for example, a mobile phone, a smartphone, a notebook, a tablet personal computer, or a personal digital assistant (PDA), but there is no particular limitation. For example, when a user makes a call via the wireless transceiver 10, the wireless transceiver 10 receives a transmission signal and wirelessly transmits it to the wireless bridge device 12.

  The wireless bridge device 12 is connected to a telephone 14 of the public switched telephone network 9. Specifically, the wireless bridge device 12 is connected between the telephone body 142 of the telephone 14 and the receiver 144, and wirelessly transmits a reception signal transmitted from the telephone body 142 to the receiver 144 to the wireless transceiver 10. Or the radio transmission / reception signal transmitted wirelessly by the wireless transceiver 10 is wirelessly received and transmitted to the telephone body 142.

As shown in FIG. 2, the wireless bridge device 22 includes a first connection port 222, a second connection port 224, a first wireless communication module 226, and a first sound source processing module 228. In actual application, the first connection port 222 is connected to the telephone body 242 and the second connection port 224 is connected to the handset 244. In this embodiment, the first connection port 222 and the second connection port 224 may be general telephone connection ports such as RJ-11, but are not limited thereto.

  The first wireless communication module 226 is connected to the first sound source processing module 228. The first wireless communication module 226 is, for example, a Bluetooth communication transmitter / receiver, a wireless LAN communication transmitter / receiver, a wireless PAN communication transmitter / receiver, a wireless fidelity communication transmitter / receiver, an IEEE 802.11 communication transmitter / receiver, or ZigBee (802.15.4). Although it may be a communication transceiver, it is not limited to this. In addition, the first wireless communication module 226 can wirelessly transmit a reception signal or wirelessly receive a transmission signal.

  The first sound source processing module 228 is connected between the first wireless communication module 226 and the first connection port 222, and between the first connection port 222 and the first wireless communication module 226. Audio format conversion is performed on the transmission signal. In actual application, the first sound source processing module 228 can convert an audio signal by converting an analog audio signal into a digital audio signal or converting a digital audio signal into an analog audio signal. .

  More specifically, the first sound source processing module 228 determines whether or not a reception signal has been received. When it is determined that the reception signal has been received, the first sound source processing module 228 determines whether or not the first sound communication module 226 and the wireless transceiver 20 have received the reception signal. Wireless connection for converting an audio signal between the telephone 24 and the wireless transceiver 20 is performed.

  In an actual application, when the first sound source processing module 228 receives a reception signal through the first connection port 222, the first sound communication processing module 228 performs a sound format conversion on the reception signal and then performs the first wireless communication module 226. Is output to the wireless transceiver 20 via. After the first sound source processing module 228 receives the reception signal, the first wireless communication module 226 wirelessly receives the transmission signal transmitted from the wireless transceiver 20 and performs voice format conversion on the transmission signal. Then, the data is output to the first connection port 222. Further, when it is determined that the reception signal is not received, the first sound source processing module 228 controls the connection with the first connection port 222 and the connection with the second connection port 224.

  Subsequently, the first sound source processing module 228 performs audio signal conversion on a transmission signal between the first connection port 222 and the first wireless communication module 226. After the first sound source processing module 228 receives the reception signal, the first wireless communication module 226 wirelessly transmits the reception signal transmitted from the telephone body 242 and transmits the transmission signal transmitted from the wireless transceiver 20. Receive wirelessly. The first sound source processing module 228 determines whether or not a reception signal has been received. If it is determined that the reception signal has not been received, the first sound source processing module 228 is connected to the first connection port 222 and the second connection port 224.

Signals can be transmitted to and from the port 224. On the other hand, the first sound source processing module 228 stops the signal transmission between the first connection port 222 and the second connection port 224, thereby causing the first connection port 222 and the second connection port 224 to communicate with each other. Signal transmission between them becomes impossible. Thereby, the first sound source processing module 228 can perform audio signal conversion on the transmission signal between the first connection port 222 and the first wireless communication module 226.

  Specifically, the initial setting of the first sound source processing module 228 is such that the user makes a phone call with the telephone body 242 and can hear a dial tone and a ringing tone of the other party's telephone through the receiver 244. This is for starting signal transmission between the connection port 222 and the second connection port 224. If the other party does not answer the call, the first sound source processing module 228 determines that the reception signal has not been received because the call connection between the two is not established, and the first connection port 222 and the second connection The signal transmission to and from the connection port 224 is maintained.

  On the other hand, when the other party answers the call, the first sound source processing module 228 determines that the received signal has been received because the call connection between both parties has been established. Then, the telephone set 24 is connected to the public switched telephone network 9 and receives an incoming call signal, and the first sound source processing module 228 stops signal transmission between the first connection port 222 and the second connection port 224. At the same time, signal transmission between the first connection port 222 and the first wireless communication module 226 is started. Thereby, the user can perform wireless communication with the wireless bridge device 22 via the wireless transceiver 20.

  For example, the user A makes a call to the user B by the telephone 24 connected to the public switched telephone network 9 and uses the telephone B to the other party telephone connected to the public switched telephone network 9. If the user is not answering the phone, the first sound source processing module 228 still maintains the transmission signal between the first connection port 222 and the second connection port 222, so that the A user can connect via the handset 244. The B user's telephone can be heard. On the other hand, when the B user answers the phone, the first sound source processing module 228 determines that the reception signal has been received, and transmits a transmission signal between the first connection port 222 and the second connection port 224. By stopping, audio signal conversion can be performed on a transmission signal between the first connection port 222 and the first wireless communication module 226. As a result, the A user and the B user can perform wireless communication by wirelessly connecting to the wireless bridge device 22 electrically connected to the telephone body 24 of the public switched telephone network 9 by the wireless transceiver 20. .
