BACKGROUND OF THE INVENTION
The present invention relates to a cordless telephone, and more particularly to an automatic call rejection response, a so-called blacklist response.
[0002]
[Prior art]
In recent years, cordless telephones have become multifunctional, and one of the multifunctional functions is blacklist response. If you register the phone number of the other party you do not want to call as a black list, when the incoming call is received, the other party's phone number is obtained by the caller ID notification service, and if the phone number is registered as a black list, This is a function that automatically sends a call rejection response to the other party, saying that it cannot be accepted due to the customer's circumstances without ringing the ringing tone. At this time, the cordless telephone base unit displays a message indicating that the black list is being answered, but the slave unit does not display it. In addition, if both the parent device and the child device perform a line capture operation, it is possible to talk with the other party during the blacklist response.
[0003]
FIG. 6 is a flowchart showing in detail the operation of the base unit of the conventional cordless telephone, particularly regarding the blacklist response. First, when there is an incoming call by the caller ID notification service (step S1), it is determined whether the other party's telephone number obtained by the caller ID notification service is registered as a black list in the memory of the master unit (step S2). If it is not registered, a ringing tone sounds (step S3), and if a line capture operation is performed in the master unit (step S4), or if a line capture operation is performed in the slave unit (step S5), a call state ( Step S6). When the line capture operation is performed in the slave unit, the actual call is performed in the slave unit through the master unit. This also applies to the call during blacklist response described below. When the call ends, the line opening operation (step S7) is performed, and the operation ends.
[0004]
On the other hand, if it is determined in step S2 that the other party's telephone number obtained by the caller ID notification service is registered as a black list in the memory of the master unit, a black list response is started (step S8). However, if a line capture operation is performed in the master unit during the blacklist response (step S9) (step S10) or a line capture operation is performed in the slave unit (step S11), the call state of step S6 is entered. . When the call ends or the black list response ends, the line release operation (step S11) is performed, and the operation ends.
[0005]
[Problems to be solved by the invention]
As described above, in the conventional cordless telephone, if both the parent device and the child device perform the line capturing operation, it is possible to make a call with the other party during the blacklist response. However, the cordless phone's master unit displays a blacklist response indicating that it is not in the state of making a call to the other party registered in the blacklist by performing a line capture operation by mistake. However, since it is unclear that the black list is being answered, there is a problem that a line capture operation is performed and a call is made to the other party registered in the black list.
[0006]
The present invention has been made in view of the above points, and an object of the present invention is to provide a cordless telephone capable of preventing a telephone conversation with a partner registered in a blacklist.
[0007]
[Means for Solving the Problems]
The first cordless telephone of the present invention has means for automatically responding to a call rejection when the other party's telephone number obtained by the caller ID notification service is registered as a call rejection number in the master unit at the time of an incoming call. In response to the rejection of the call, the base unit includes means for prohibiting acceptance of a line capture request from the slave unit, and if the line capture request is not accepted by the base unit, the slave unit terminates the operation . It is characterized by that.

The LCD display unit 13 displays various information such as the received caller's telephone number. The RAM 14 stores various information such as the telephone number of the received caller and also has a memory function as a telephone directory. Further, the RAM 14 is also used as a memory for a black list, and stores a black list telephone number. The message recording unit 15 stores a response message in the absence recording mode, a message at the time of blacklist response, a message from the received caller, and the like. The hook switch 16 determines whether or not the handset is placed on the base unit 10.
[0012]
Reference numeral 17 denotes a line terminal to which an incoming call detection circuit 18 for detecting a ringer signal is connected, and an output of the incoming call detection circuit 18 is connected to the CPU 11. 19 is a rectifier circuit that prevents the voltage and polarity inversion of the line terminal 17 from affecting the inside of the telephone, 20 is a DP transmission circuit that connects and disconnects the line, and 21 is a speech network IC that performs 2-wire to 4-wire conversion. The line terminal 17 is connected to the CPU 11 via these circuits. The speech network IC 21 is connected to a receiver 22, a microphone 23, a speaker 24, and a caller IDIC 25, and an output of the caller IDIC 25 is connected to the CPU 11. The cola IDIC 25 is a circuit that determines the telephone number of the received caller. Furthermore, the speech network IC 21 and the CPU 11 are connected to the RF module 27 via the compander IC 26 in order to perform wireless communication with the slave unit, and the antenna 28 is connected to the RF module 27. Further, the base unit 10 has a power supply circuit 29, and power is supplied from the power supply circuit 29 to the respective units.
[0013]
A slave unit 30 shown in FIG. 5 has a CPU 31 that controls the entire slave unit, and an RF module 33 and a compander IC 34 are connected to the CPU 31 for wireless communication with the master unit 10. An antenna 32 is connected to 33. The compander IC 34 has an audio output unit connected to the speaker 36 via the amplifier 35 and a microphone 37 connected to the audio input unit. Similarly to the base unit 10, a key input unit 38 for inputting information, an LCD display unit 39 for displaying information, and a ROM 40 for storing various types of information including ID data are connected to the CPU 31. Furthermore, the subunit | mobile_unit 30 has the power supply circuit 41, and electric power is supplied from the power supply circuit 41 to each said part.
[0014]
In the base unit 10 and the handset 30 of the cordless telephone configured as described above, if the incoming call in the caller number notification service is the base unit 10 as shown in the sequence diagram of FIG. Searches the blacklist memory to determine whether the other party's telephone number obtained by the caller ID notification service is registered in the blacklist. If the other party's phone number is registered in the black list, the ring tone does not sound in the main unit 10 and the sub unit 30 and the message “cannot be accepted due to customer's convenience” is displayed in black. It is sent to the other party as a list response. Furthermore, even if a line capture operation, that is, a call key press or off-credor is performed in the slave unit 30 during the blacklist response, the master unit 10 does not accept a line capture request from the slave unit 30. Therefore, the slave unit 30 does not capture the line and does not enter a call state. As a result, during the black list response, the slave unit 30 does not enter a state where a call is made with the other party registered in the black list. Thereafter, since the slave unit 30 does not receive a response from the master unit 10, an error sound sounds when the timeout occurs, and the operation ends. The master unit 10 also disconnects after completing the blacklist response, and the operation ends.
[0015]
FIG. 2 is a flowchart showing the operation of base unit 10 among the operations as described above. To explain this, when there is an incoming call by the caller ID notification service (step S21), the other party's phone number obtained by the caller ID notification service is registered as a black list in the blacklist memory of the master unit. (Step S22), if it is not registered, a ringing tone sounds (step S23), and if the line acquisition operation is performed in the parent device (step S24), or if the line acquisition operation is performed in the child device (Step S25), a call state (Step S26) is entered. When the line capture operation is performed in the slave unit, the actual call is performed in the slave unit through the master unit. When the call is finished, the line opening operation is performed (step S27), and the operation is finished.
[0016]
On the other hand, if it is determined in step S22 that the other party's telephone number obtained by the caller ID notification service is registered as a black list in the black list memory of base unit 10, a black list response is started (step S22). S28). If a line capture operation is performed in the base unit 10 during the black list response (step S29) (step S30), the communication state of step S26 is entered. However, since the base unit 10 displays a message indicating that the black list is being responded, it is possible to avoid a state in which a line capture operation is mistakenly performed and a call is made with the other party registered in the black list. During the blacklist response, the master unit 10 does not accept a line capture request from the slave unit 30. When the black list response ends, the line release operation (step S27) is performed, and the operation ends.
[0017]
FIG. 3 is a flowchart showing the operation of the slave unit 30. Normally, when a slave unit 30 performs a line capture operation, that is, when a call key is pressed or an off credor (step S41), the slave unit 30 sends a line capture request to the master unit 10. Is transmitted (step S42), and if there is a response from the base unit 10 (step S43), the line is captured (step S44), and a call is possible (step S45). When the call is finished, the line opening operation is performed (step S46), and the operation is finished. On the other hand, when a line capture request is sent to the base unit 10 in step S42, if the base unit 10 is in a blacklist response, in the present invention, the base unit 10 does not accept the line capture request and the response from the base unit 10 Therefore, the slave unit 30 sounds an error sound when the timeout occurs in step S47, and the operation ends.
[0018]
As described above, according to the above-described embodiment, since the master unit 10 does not accept a line capture request from the slave unit 30 during the blacklist response, the slave unit 30 does not enter a call state. Even if the line capture operation is performed, it is possible to prevent a situation in which a call is made between the slave unit 30 and the other party registered in the black list during the black list response. Further, according to this method, that is, according to the method in which the base unit 10 does not accept the line capture request from the handset 30 during the black list response, it is only necessary to change the part of the base unit 10 so that the request is not accepted. Since the slave unit 30 may have the same configuration as the conventional one, the purpose can be realized very easily.
[0019]
In the above embodiment, the base unit 10 does not accept the line capture request from the slave unit 30 during the black list response. However, as another method, the master unit 10 does not accept the line capture request from the slave unit 30 during the black list response. It is also possible to send a signal to 30 and display on the LCD display unit 39 (FIG. 5) of the slave unit 30 that the master unit 10 is currently responding to the black list. According to this method, it is possible to avoid talking with the other party registered in the black list by looking at the display on the LCD display unit 39 of the slave unit 30, and in some cases, such as calling and complaining. Can be taken.
