[0015]
Now, the operation of the main part of the key telephone apparatus configured as described above will be described with reference to the flowcharts of FIGS.
Here, the flowcharts of FIGS. 3 and 4 show an example in which, when an incoming call arrives at the mobile telephone 5B from outside, an indication of the incoming of the mobile telephone 5B is displayed on the corresponding key telephone 3B as an example. When an incoming call arrives at the mobile telephone 5A from outside, the effect of the incoming call at the mobile telephone 5A can be similarly displayed on the corresponding key telephone 3A. When an incoming call arrives at the mobile telephone 5C from the outside, the incoming of the mobile telephone 5C is received. Can be displayed on the corresponding key telephone 3C in the same manner.
[0016]
First, the operation of the interface box 4 shown in the flowchart of FIG. 3 will be described.
When the mobile telephone 5 is placed on the interface box 4 and connected to the mobile telephone interface 42, the control unit 44 of the interface box moves the presence / absence of an incoming call of the mobile telephones 5A to 5N based on a call from an external caller. It is detected via the telephone interfaces 42A to 42N.
Here, when the control unit 44 detects, via the mobile telephone interface 42B, an incoming call addressed to, for example, the mobile telephone 5B placed and connected to the interface box 4, the control unit 44 changes “Y” to “Y” in step S1. Is determined.
[0017]
In this case, the control unit 44 transmits incoming data to the main device 2 via the transmission circuit 41 to the main device 2 in step S2. Thus, the main device 2 recognizes that the mobile telephone 5B is receiving a call, and displays an incoming call on the key telephone 3 that the mobile telephone 5B is receiving a call.
After transmitting the incoming data, the control unit 44 determines in step S3 whether or not the incoming call to the mobile telephone 5B has been lost. It is determined in step S5 whether there is a response request from the main device 2 to the telephone 5B.
[0018]
Here, if the external caller abandons the call to the mobile telephone 5B during the incoming of the mobile telephone 5B, and the determination of "is the termination of the incoming of the mobile telephone 5B?" At S4, incoming end data indicating the end of incoming call of the mobile telephone 5B is transmitted to the main device 2 via the transmission circuit 41, and the mobile phone 5B shifts to an idle state. Thereby, control unit 2D of main device 2 recognizes that the incoming state of mobile telephone 5B has been released.
[0019]
When an incoming call response operation is performed on the side of the key telephone 3 displaying that the mobile telephone 5B is receiving an incoming call to the mobile telephone 5B, the control unit 2D of the main device 2 disconnects the extension interface 2A. The response operation is detected through the switch and the switch 2C is controlled to form an extension call path between the response key telephone 3 and the mobile telephone 5B. Then, an incoming call response request to the mobile telephone 5B is transmitted to the interface box 4 via the extension interface 2A. When receiving the incoming call response request via the transmission circuit 41, the control unit 44 of the interface box 4 determines "Y" for "Receive incoming call request from main device to mobile phone 5B?" In step S5.
[0020]
In this case, the control unit 44 transmits the incoming call response request to the mobile telephone 5B via the mobile telephone interface 42B in step S6, and connects the mobile telephone 5B to a wireless communication channel. In this way, a communication path between the key telephone 3 that has responded to the incoming call and the external caller is formed by the route of the main unit 2, the interface box 4, and the mobile telephone 5B, and the user (employee) of the key telephone 3 communicates with the external caller. A call with the caller via the call path is started.
[0021]
If the external caller ends during a call between the user of the key telephone 3 and the external caller, the control unit 44 of the interface box 4 detects the end as the end of the mobile telephone 5B. When the end of the call of the mobile telephone 5B is detected via the mobile telephone interface 42B and the determination in step S7 becomes “Y”, the control unit 44 sends the main telephone 2 to the main apparatus 2 via the transmission circuit 41 in step S8. The call termination data is transmitted to open the extension call path between the key telephone 3 and the mobile telephone 5 during the call, and the mobile telephone 5B is instructed to open the radio communication channel via the mobile telephone interface 42B, and the communication channel is transmitted. Release. Then, the state shifts to the idle state.
[0022]
Further, when the end of the key telephone 3 is detected by the main unit 2 during a call between the user of the key telephone 3 and the external caller, the control unit 2D of the main unit 2 controls the switch 2C. The extension call path between the key telephone 3 and the mobile phone 5 during the call is opened, and a call termination request of the mobile phone 5B is transmitted to the extension interface box 4. Upon receiving the call termination request data via the transmission circuit 41, the control unit 44 of the interface box 4 determines "Y" for "reception of a call termination request for the mobile phone 5B from the main device?" In this case, the control unit 44 transmits the call termination request data to the mobile telephone 5B via the mobile telephone interface 42B in step S10, and releases the communication channel.
[0023]
FIG. 4 is a flowchart showing the operation of the main device 2 responding to the interface box 4 performing the above operation. The operation of the main part of the main device 2 will be described based on this flowchart.
