Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a communication terminal device such as a telephone connected to a network such as a public line network.

[0002]

2. Description of the Related Art Conventionally, some telephones connected to a public line network have a function of displaying a line number (telephone number) of a caller. For example, JP-A-1-300
Japanese Patent No. 751 discloses a telephone having a function of transmitting a line number when a line is connected to a calling telephone and displaying a line number transmitted from the calling side when the line is connected. Have been. However, in this telephone, the receiving side could not display the calling side line number unless the calling side telephone had the function of transmitting the line number.

[0003] Recently, a service (caller ID notification service) for notifying a called side of a line number of a calling side from a public line network (switching machine) has been implemented, and a line of the calling side transmitted from the switching machine has been implemented. Number display function (so-called,
Telephones provided with a number display function) have been proposed.

[0004] The caller ID notification service will be briefly described below.

This caller ID notification service is a service in which an exchange notifies a called side of a line number of a calling side.
It is possible to notify the called party of the line number of the calling party regardless of the function of the telephone set of the calling party. Hereinafter, processing in the exchange will be described. Switch is any telephone (calling side)
Transmits the caller ID notification signal shown in FIG. 3A to the designated station (receiving side) and waits until the receiving side goes off-hook (waits for line connection). When the line with the called side is connected, the exchange transmits the line number of the calling side and disconnects the line with the called side. At this time, the calling side and the called side are not connected. Further, the exchange transmits a connection request shown in FIG. 3 (B) to the called side, and when the called side goes off-hook, connects the calling side and the called side.

In order to display the line number of the caller using the caller ID notification service, a conventional telephone has a function of switching the main body from an on-hook state to an off-hook state when receiving the caller number notification signal. (Line connection function), and a function of switching the main body from an off-hook state to an on-hook state when receiving the transmission line number transmitted from the exchange, and displaying the received transmission line number. . It should be noted that, similarly to a general telephone, when the connection request is received, a notification function using a ring tone or the like and a communication function are provided.

[0007]

The above-mentioned caller ID notification service, which is generally implemented, is provided only to users (lines) registered with a public network management company (eg, NTT). Have been. That is, the service is not provided to a user who has not registered. On the other hand, it is desirable that the telephone can be used in either the environment where the service is provided or the environment where the service is not provided. Therefore, the conventional telephone is configured so that the number display function can be switched between an on state (in an environment where the service is provided) and an off state (in an environment where the service is not provided). Was.

However, since the conventional telephone has a configuration in which the user performs the above-described switching operation, the number display function is turned off in an environment where the service is provided, or conversely, In some cases, the number display function is turned on even in an environment where the service is not provided. In this case, the following problem occurs.

[0009] For example, if the number display function is off in an environment where the service is provided, the telephone makes a ringing tone when receiving a caller ID notification signal transmitted from the exchange. This is because the telephone recognizes the caller ID notification signal as a connection request signal. On the other hand, the exchange forcibly terminates this processing if the line is not connected (the user does not pick up the handset) within a predetermined time after the transmission of the caller ID notification signal is started. In this case, the exchange sends a signal to the calling side indicating that the called side is busy. Therefore, communication cannot be performed without connection between the calling side and the called side.

Further, when the user picks up the handset or switches from on-hook to off-hook in the well-known answering machine function and the line between the exchange and the called side is connected, the exchange switches the calling side to the called side. Send the line number of At this time, the receiver on the receiving side outputs the line number (tone signal) of the calling side transmitted from the exchange, so that the receiving side can recognize where the call came from or whether it was a mischievous or incorrect call. Can not do it. In addition, when the exchange transmits the line number of the calling side, it temporarily disconnects the line and transmits a connection request signal. At this time, if the telephone of the called side remains off-hook (for example, the user picks up the handset). Switch), the switch recognizes that the called line is busy,
A signal is transmitted to the transmitting side indicating that the receiving side is busy. Therefore, also in this case, the calling side and the called side are not connected and communication cannot be performed.

On the other hand, if the number display function is set to the ON state in an environment where the service is not provided, the exchange transmits a caller ID notification signal and a caller's line number to the receiver's telephone. Since the connection request signal is transmitted without receiving the message, the telephone recognizes that the reception-side line number has not been actually transmitted (the message of the reception error is displayed). This gives the user anxiety that the telephone is out of order. When the telephone receives the connection request, the telephone starts notification by a ringing tone. When the user picks up the telephone, the line between the calling side and the called side is connected, and the calling side and the called side can communicate with each other.

An object of the present invention is to switch an on / off state of a function of outputting a line number of a calling side transmitted from a network before connecting a line with the calling side in accordance with a use environment of the apparatus main body. It is an object of the present invention to provide a communication terminal device capable of performing such operations.

[0013]

According to the present invention, after transmitting a predetermined signal, the network is connected to a network for transmitting the line number of the transmitting side, and when the predetermined signal is transmitted from the network, the line is switched. A communication terminal device having a caller number output means for connecting and receiving a caller number transmitted from the network and outputting the received caller number, wherein the caller number output means is in an ON state or Switching means for switching off state;
Setting change means for switching the caller number output means to the on state when the predetermined signal is received when the caller number output means is in the off state.

A setting for switching the caller number output means to an off state when the caller number output means is on and another signal is received without receiving the predetermined signal from the network. Changing means.

Further, there is provided a notifying means for outputting that the switching by the setting changing means has been performed.

In the above configuration, when a predetermined signal is transmitted from the network, the caller number output means is switched to the on state if the caller number output means is in the off state. The predetermined signal may be a caller ID notification signal in a generally implemented caller ID notification service. This allows
When the apparatus is used in an environment where the caller ID notification service is provided, the caller ID output means can be turned on to use the apparatus main body.

When another signal is received without receiving the predetermined signal, if the caller number output means is in an on state, the caller number output means is switched to an off state. The other signal is, for example, a connection request signal. Therefore, when the apparatus is used in an environment where the caller ID notification service is not provided, the apparatus main body can be used with the caller ID output means turned off.

Further, since the notification means outputs the switching of the caller number output means between the ON state and the OFF state, the user can recognize that the apparatus body has been switched to a state suitable for the use environment. Can be.

FIG. 1 is a block diagram showing the configuration of a telephone according to an embodiment of the present invention. In the figure,
1 is a telephone body, and 2 is a control unit for controlling the operation of the telephone 1. Reference numeral 3 denotes a receiver in which a microphone and a speaker are arranged, 4 denotes an operation unit in which dial keys and the like are arranged, 5
Is a display unit, 6 is a notification unit for performing notification when a call is turned on, 7 is a communication unit that controls signals input and output via a line, and 8 is an on-hook unit that switches between an on-hook state and an off-hook state. In addition, the telephone 1 according to the present embodiment displays the transmission-side line number on the display unit 5 when the transmission-side line number is transmitted from the exchange arranged on the network before the line with the transmission-side is connected. It has a caller number output function for displaying (a so-called number display function), and further has a function of switching the caller number output function between an ON state and an OFF state. Note that the telephone 1 according to this embodiment is also connected to a public line network like a general telephone, and has a function of communicating with a station connected to the line via the public line network.

FIG. 2 is a flowchart showing a process at the time of an incoming call of the telephone according to the embodiment of the present invention. Note that the processing at the time of making a call on the telephone 1 is the same as that of a known telephone, and a description thereof will be omitted. The telephone 1 is a communication unit 7
When a signal transmitted from the public line network is received, whether the received signal is a caller ID notification signal,
It is determined whether the signal is a connection request signal (n1, n2). At this time, the telephone 1 is in an on-hook state. The caller number notification signal is a pulse signal having a period of 1 s as shown in FIG. 3A, and has a pulse width of 0.5 s. On the other hand, the connection request signal is a pulse signal having a period of 3 s and a pulse width of 1 s as shown in FIG. The control unit 2 includes a communication unit 7
If it is determined that the received signal is a caller number notification signal, it is determined whether or not the caller number output function is on (n3). When it is determined that the signal received by the communication unit 7 is a connection request signal, it is determined whether or not the caller number output function is off (n4).

If it is determined in step n3 that the caller number output function is in the off state, the function is switched to the on state (n
5) The telephone 1 is set to the off-hook state to connect the line (n6). If it is determined in step n3 that the caller number output function is on, the flow advances to step n6 to place the telephone 1 in the off-hook state and connect the line. In n6, only the line between the telephone 1 and the exchange is connected, but not to the calling telephone. Since the caller ID notification signal has been transmitted from the exchange, the telephone 1 is used in an environment where a caller ID notification service is provided. That is, the telephone 1 determines whether or not the environment provides the caller ID notification service based on whether or not the caller ID notification signal has been transmitted from the exchange. Note that, while receiving the caller number notification signal, the telephone 1 does not perform notification by the ringing tone in the notification unit 6.

When the line with telephone 1 is connected, the exchange transmits the line number of the calling side to telephone 1 as a tone signal. The telephone 1 receives the line number of the calling side transmitted from the exchange by the communication section 7 (n7), and disconnects the line by switching the main body to the on-hook state (n8). Further, the line number received at n7 is displayed on the display unit 5 (n9). On the other hand, upon detecting that the line with the telephone 1 has been disconnected at n8, the exchange transmits a connection request signal shown in FIG. When the telephone 1 receives this connection request signal (n10), the notification unit 6 starts to notify by a ringing tone (n11), and the main unit goes off-hook due to the handset 3 being picked up (n1).
2) Wait until the connection request signal stops (n1)
3). When the telephone goes off-hook at n12 (at this time, the line between the telephone 1 and the calling side is connected), the telephone 1 performs a known call process (n14). On the other hand, when the connection request signal is stopped at n13 (as is well known, when the transmitting side is in the on-hook state), the notification by the ringing sound in the notification unit 6 is stopped (n15). When the telephone 1 completes the process of n14 or n15, if the caller number output function is switched from the off state to the on state in n5 (n16), the display unit 5 turns on the caller number output function. A message indicating that the state has been switched is displayed, and the process ends (n16). For example, "Since the caller ID display function was set to off, it was switched on. Is displayed.

As described above, when the telephone 1 according to the present embodiment is used in an environment where the caller ID notification service is provided, if the caller ID output function is in the OFF state, it is switched to the ON state. Therefore, in an environment where the caller ID notification service is provided, the telephone 1 can be used with the caller ID output function always on.

If it is determined in step n4 that the switch is in the off state, the process from step n11 is performed. On the other hand, if it is determined in n4 that it is in the on state, the state is switched to off in n18, and the processing from n10 onward is executed.

When the connection request signal is transmitted without transmitting the caller ID notification signal from the exchange, the telephone 1 is used in an environment where the caller ID notification service is not provided. In n17, n
If the caller number output function has been switched from the on state to the off state at 18, a message indicating that the caller number output function has been switched to the off state is displayed on the display unit 5. For example, "Since the caller ID display function was set to the ON state, it was switched to the OFF state. Is displayed.

As described above, when the telephone 1 according to this embodiment is used in an environment where the caller ID notification service is not provided, the telephone 1 is switched to the OFF state when the caller ID output function is ON. Therefore, in an environment where the caller ID notification service is not provided, the telephone 1 can always be used with the caller ID output function turned off. Therefore, the telephone 1 can always be used in a state according to the usage environment.

Further, when the state of the caller ID notification function is switched, a message to that effect is displayed, so that the user can be notified that the state of the telephone 1 has been switched.

The present invention can also be applied to a telephone having other functions such as a known answering machine function and a fax function. In the above-described embodiment, the display unit 6 indicates that the state of the caller ID notification function has been switched. However, for example, a telephone having a fax function may print out this message, If the telephone has a telephone number, a message to that effect may be recorded on a tape, or the user may be notified by lighting a light emitting element such as an LED instead of the message.

[0029]

As described above, according to the present invention, it is determined whether or not the apparatus main body is in an environment in which the caller ID notification service is provided. When the state is not appropriate, it can be switched to the appropriate state. Therefore, the apparatus main body can always be used in a state according to the use environment.

Further, when the state of the apparatus main body is switched, the fact is notified so that it can be easily confirmed that the state of the apparatus main body has been switched.
