There are a connection 77 and a connection 78 between the MPU 20 and the analog switch 21 constituting the control device 2. The MPU 20 starts operating by the connection button 22. For example, when the caller of the base station 1 moves away from the base station and leaves the base station, turning on the connection button 22 causes the control device 2 to start operating, enabling the two-way communication with the cordless telephone. Therefore, if the system according to the present invention is used, the base unit 3 of the cordless telephone can freely talk to the mobile unit 4, so that the mobile unit 5 can call the mobile unit 5, and conversely, the mobile unit 5 can be called from the mobile unit 4. Call intercommunication can take place.

[0014]

[Contents of Correction] In the data A, transmission / reception of a call between the base station 1 and the control device 2, call termination, and mobile station number data are performed.
In the case of the data B, transmission / reception of incoming / outgoing calls, termination, and mobile station number data between the control device 2 and the base unit 3 are performed. Here, based on the respective functions, the connections 72, 73, 75, 76 are collectively called a data transmission / reception line, and the connections 70, 71 are collectively called a transmission / reception setting line. In addition, connection 74 is referred to as a call setup line.

Next, the operation when a call is established between the mobile station 5 and the slave unit 4 will be described. When the connection button (connection switch) 22 indicates the ON state (setting state), the mobile station 5
, An incoming call signal is generated in the base station 1. Upon detecting the incoming call signal, the base station 1
The data A is transmitted to the PU 20. The base station 1 turns off after a certain period of time, for example, three seconds, has elapsed since the detection of the incoming call signal. For this reason, the MPU 20 sets the transmission state by turning on the press talk switch of the base station 1 while calling the slave unit. By setting the transmission state, a call between the mobile station 5 and the base station 1 is held. In the meantime, the calling of the slave unit 4 and the setting of the call state are executed by the data B via the master unit. During this time, the MPU 20 generates an alarm signal,
The terminal a of the analog switch 21 is turned on via the connection 77, and an alarm sound is transmitted to the mobile station 5.
The alarm sound has a content indicating that the handset 4 is being called.

When the slave unit 4 is called up, the MPU 20
8, the terminals b and c of the analog switch 21 are turned on to connect the base station 1 and the base unit 3. As a result, voice transmission / reception between the mobile station 5 and the handset 4 can be performed. At this time, the terminal a of the analog switch 21 is turned off to interrupt the transmission of the alarm signal.

At this time, since the communication of the MCA radio operates in a one-way communication (simplex communication) and the communication of the cordless telephone operates in a round-trip communication (reception communication), the control unit 2 presses the signal from the slave unit 4 during the communication. A talk-on / off signal is output, whereby the press-to-talk switch of the base station 1 is turned on / off to switch between transmission and reception, thereby enabling mutual communication.

FIG. 3 is a flowchart showing the operation of the MPU 20 of the embodiment. When there is an incoming call signal 100 from the MCA radio, the press talk is turned on 101 and the slave is called 102 via the master. In the meantime, the alarm sound is sent to the MCA radio 103, the slave responds 104, and the transmission of the alarm sound is terminated 106 at the same time as the line between the master and the slave is connected 105, and the communication between the slave and the MCA radio is performed. The audio line is connected 107, and a call is started 108. Push the end button of the slave unit 109 or there is an end signal from the MCA radio 1
10 and top talk are turned off 111, and the audio lines of the slave unit and the MCA radio are turned off.

Conversely, when calling the mobile station 5 from the handset 4, the MCA radio communication button attached to the handset 4 is turned on, or another method, for example, a specific number for operating the control device 2 is set. The master unit 3 accesses the MPU 20 of the control device 2 via the connection 74 by dialing or the like. Group call and simultaneous call are possible. That is, for example, if desired, not only the single mobile station 5 but also the base station 1 and the mobile station 5, or at least two or more mobile stations 5 can be accessed simultaneously. MPU 20 sends out a call signal and a call mode signal to base station 1 via connection 70. When the mobile station 5 is called from the base station 1 via the control center and responds, the communication state is established.

In the embodiment, the method of connecting the line between the mobile station 5 and the handset 4 has been described. However, the connection between the mobile station 5 and the base unit 3 and between the base station 1 and the handset 4 are the same as those in the embodiment. Can be accessed in the same way.

Further, in the embodiment, the control device 2 is interposed between the base station 1 and the master unit 4, but may be configured integrally with the control device 2 and the master unit 4. Further, in the embodiment, the connection of the line between the cordless telephone and the MCA radio has been described. However, the present invention can be applied to a wireless communication device other than the cordless telephone, for example, a specific low power wireless telephone device. Therefore, other than the above-described embodiments, various modifications can be made without departing from the scope of the present invention.
