2. Description of the Related Art Remote control of a telephone uses a telephone capable of transmitting a PB signal from a remote place. First, a selection signal is transmitted to call a telephone at home, and then a specific number such as a password is entered. It transmits a message to control a specific additional function.

[0003] Additional functions include, for example, a remote control function for listening to recorded contents recorded on an answering machine at home from outside, a transfer function for transferring recorded contents, and a selective reception function for ringing a ringer only when a password is transmitted. ,
In addition, various functions such as a terminal designation function that allows one of the terminal designation numbers set in advance for each cordless handset to be made to ring the ringer only for a particular cordless handset in a cordless telephone having a plurality of cordless handsets There is.

However, in order to remotely control these various additional functions, it is necessary to transmit a specific number such as a personal identification number. Therefore, a telephone capable of transmitting a PB signal such as a push-button telephone is used. Have to be restricted. This is because some exchanges do not pass the DP signal.

[0005] Except for a remote control function for listening to secret recording contents that are difficult to be heard by others, such as a remote control function, it is desirable to use a personal identification number. Some of the additional functions described above do not necessarily require the input of a password or a specific number.

Embodiments of the present invention will be described below with reference to the drawings.
The present embodiment relates to a cordless telephone having a plurality of cordless handsets, and relates to a cordless telephone having a terminal designation function capable of designating and calling a specific one of a parent cord and a plurality of cordless handsets.

FIG. 1 to FIG. 3 show a first embodiment of the present invention, in which an external telephone can transmit either a DP signal or a PB signal, and is set to a terminal designation mode by remote control. Switching is further performed so that a specific terminal of the parent device or a plurality of child devices can be designated and called.

FIG. 1 is a block diagram of a first embodiment, wherein an external telephone set a capable of transmitting a DP signal or a PB signal, a base unit b of a cordless telephone connected to the line, and a base unit b which are wirelessly connected. Cordless telephone handsets c to e.

First, the user of the cordless telephone sets, for example, the slave unit c to be designated and called, and sets a set number of times to be described later to two and a set time to one minute. This setting may be made so that selection of the master unit b and slave units c to e and various settings can be arbitrarily made by, for example, display means and setting switches (not shown). The cordless telephone set with the parent device or the child device designated to be called in this way waits for an incoming call in the normal standby state in which the terminal designation mode is released.

A caller who knows that this cordless telephone is set to be able to call by designating only the handset c dials the cordless telephone from the external telephone a,
At that time, when a ringback tone transmitted from the exchange of the office is heard once, the telephone goes off-hook and the line is temporarily disconnected. Base unit b of the cordless telephone receives the intermittent call signal corresponding to the ring back tone from the exchange, detects the number of intermittent calls, and detects the call signal less than the set number of times (two times). When the line disconnection is detected at the point of time, the mode is automatically switched to the terminal designation mode.

FIG. 3 shows a waveform diagram of the call signal and the number of times the call signal is interrupted.

Further, when a call is received again within one minute which is a set time after switching to the terminal designation mode, the parent device b notifies only the preset child device c by ringing or displaying. ing. Therefore, if there is no incoming call even after the elapse of one minute of the set time, the terminal designation mode is canceled and the apparatus is switched to the normal standby state again.

When an incoming call is detected in the normal standby state, the base unit b determines that there is an incoming call immediately when the call signal is detected once, and the base unit b and the handset c. -E is not ringed, and all the terminals of the parent device b and the child devices c-e are ringed or displayed only when the call signal is detected twice, which is the set number of times. Notify incoming call. Since the notification is started only when the number of intermittent times detected in this way is equal to or greater than a preset number of times, a switch to the terminal designation mode without being off-hook by one of the slave units by mistake. We are sure. Further, since the set number is set to two or several times, there is no practical problem.

Further, the terminal designation function in the terminal designation mode is executed only when an incoming call is detected again within a relatively short set time after the line disconnection is detected and the mode is switched to the terminal designation mode. It is very unlikely that a specific terminal is erroneously called by detecting an incoming call from another caller who is not intended to designate a terminal within a practically practical range.

Next, FIG. 2 is a block diagram of the cordless telephone according to the first embodiment, showing a state in which a master unit b and a slave unit c are wirelessly connected. Note that the slave units d and e are the same as the slave unit c and will not be described.

As shown in FIG.
4-wire conversion circuit 2, radio transmitter-receiver 3, signal detector 4 capable of detecting a signal such as a calling signal, control circuit 5, ID-ROM
6. It is composed of each block of an answering machine 7 composed of recording and reproducing means and the like. In addition to controlling the cordless telephone function, the control circuit 5 stores the number of interruptions of the call signal detected by the signal detector 4, the preset number of times (about two or several times) and the number of interruptions detected Comparison, switching between control mode state such as terminal designation mode and normal standby state, time measurement after switching to control mode state such as terminal designation mode by built-in timer, time measured and preset time set , Setting of a terminal to be designated (the parent device b itself or the child devices c to e), and various kinds of control such as ringing and display notification control of incoming calls. Also I
The D-ROM 6 stores a common identification code for the parent device b and the child devices c to e and an identification code unique to each child device.

The slave c, which is wirelessly connected to the master b, includes a wireless transmitter / receiver 8, a control circuit 9, a dial circuit 10, an ID-
It is composed of blocks of the ROM 11. ID-R
The OM 11 stores a common identification code for the parent device b and the child devices c to e and an identification code unique to the child device c. Each of the slaves d and e (not shown) stores a common identification code and an identification code unique to the slave itself in the ID-ROM.

The wireless line connecting the master unit b and the slave units c to e has a control channel (1-2 channels) and a plurality of communication channels (several tens of channels). The latter is used for ringing tones and telephone calls for connection between machines.

With this configuration, if there is an incoming call from the outside in the normal standby state, the signal detector 4 detects the calling signal, and the control circuit 5 determines that the number of intermittent calls is less than the set number (two times). When it is detected that the line is disconnected only once, the mode is switched to the terminal designation mode. Further, when an incoming call is detected again within one minute which is a set time after the line is disconnected, only the slave unit c which is designated in advance and set so as to be able to call is sounded or the like, and is notified.

FIG. 4 is a sequence diagram showing a second embodiment of the present invention. The present embodiment relates to a case where an external telephone capable of transmitting a PB signal is used. In a cordless telephone having a plurality of slaves, it is possible to designate and call only a specific terminal of the master or a plurality of slaves. The present invention relates to a telephone terminal device having a terminal designation function that can be used. Since the cordless telephone can be realized by the same configuration as that shown in FIGS. 1 and 2, the description will be made based on the cordless telephone shown in FIGS.

In FIG. 4, when a master unit b detects an incoming call from the telephone line 1 in a standby state, each of the slave units n (n is c to
In step e), a call channel is designated, and an incoming call request signal and an identification code IDn (n is c to e) of the slave unit are transmitted on the control channel.

Each slave unit n, upon receiving this, transmits an incoming call response signal together with the identification code IDn on the control channel.
At this time, the slave unit n switches to the designated channel, and transmits a channel switching completion signal when it confirms the availability of the channel.

The base unit b detects the ringing signal (ringer sound) of 16 Hz shown in FIG. 3 which is intermittently transmitted from the line 1 once, less than a set number of times (two times), and disconnects the line. When it is detected, it automatically switches to terminal designation mode. At this time, a line disconnection signal and an identification code IDn are transmitted to each slave unit n, and each slave unit n is again placed in a standby state. Note that the master unit b
Does not transmit a ringing sound signal to each slave unit n when detecting the calling signal once, and does not notify that there is an incoming call. When the call signal is detected twice, which is the set number of times, the master device b and all the slave devices n are notified all at once based on the subsequent call signals.

When the main unit b switches to the terminal designation mode,
From that point, the timer starts counting time. If the incoming call is not detected again even after the set time of one minute has elapsed, the terminal designation mode is canceled and the mode is switched to the normal standby state. If there is an incoming call within one minute, the designated channel of the slave unit n is switched again to be in a state of waiting for the input of the designated terminal number. Subsequently, when a designated terminal number is received from the line, a ringing signal and an identification code IDn based on the designated terminal number are transmitted, and only the designated slave unit is caused to ring.

The designated terminal number is, for example, “# 1” for the parent device b itself, “# 2” for the child device c, and “# 2” for the child device d.
"3" for the slave unit e and "# 4" for the slave unit, and the caller can designate and call the master unit or a specific slave unit by inputting the designated terminal number together with the selection signal. If the designated terminal number has not been input, it is determined that the parent device b does not designate a specific terminal, and if the number of intermittent paging signals at this time is detected more than the set number of times again, the parent device b and the child device If all of c to e are notified by ringing or the like, and if the line disconnection is detected less than the set number of times, the state of switching to the terminal designation mode is maintained, and it waits for an incoming call again within the set time after the line disconnection.

Further, if this function is used, not only the designation of the master unit b or the slave units c to e, but also, for example, when "# 5" is inputted, the recording / reproducing means incorporated in the master unit b of FIG. The present invention can be applied to various applications such as putting the cordless telephone in the answering machine recording state by using the answering machine 7 having the function.

As described above, in the first and second embodiments,
Although the number of setting times is set to two and the setting time is set to one minute, the present invention is not limited to this, and is configured so that a cordless telephone user can set arbitrarily with a certain degree of freedom. Further, this setting may be set for each master unit or each slave unit.

In the first embodiment, an example is shown in which only the slave unit c is called. However, the present invention is not limited to this, and any one of the master unit b or the slave units c to e is designated. Needless to say, it can be set arbitrarily so that it can be called.

Further, in the first embodiment, for example, when the set number of times is set to four times and the line is disconnected when a call signal is detected once, the built-in answering machine 7 is controlled to control the answering machine. In order to switch to the recording mode, the terminal designation mode is used to designate the slave unit c when the line is detected twice and the line is disconnected, and the slave unit d is designated when the line is disconnected and detected three times. To switch to terminal designation mode respectively,
It is also possible to easily switch to a control mode for performing a preset additional function for each detected number of interruptions. By setting a predetermined additional function to be controlled for each intermittent call signal, a plurality of additional functions can be easily remotely controlled from an external telephone that transmits only the DP signal.

Further, in the second embodiment, the caller transmits a designated terminal number such as "# 1" together with the selection signal within a set time after the line disconnection. The caller will send only the selection signal within
The parent device b states that “this telephone is currently switched to the additional function mode”, “if a parent device or a child device is to be called, it is necessary to input a password within a predetermined time”, and If the designation is not performed, an instruction to instruct the user to wait as it is "may be made using the automatic response function of the answering machine 7.

In the first and second embodiments, the terminal designation function for designating and calling a parent unit or a specific child unit of a cordless telephone having a plurality of child units has been described. However, the present invention is not limited to this. However, the present invention can be applied to remote control of various additional functions such as remote control of an answering machine function of an answering machine as described in the second embodiment.

In the terminal designation function described in the first and second embodiments, only the designated terminal is called for the first time after an incoming call is detected again within a set time after the line is disconnected and switched to the terminal designation mode. In a control mode such as the answering machine recording mode, if there is an incoming call during normal standby and a line disconnection is detected less than the set number of times, the mode is switched to the control mode and it can be executed. . However, even in the additional functions such as the answering machine recording function, the control mode is detected by detecting a line disconnection and switching to a predetermined control mode and detecting an incoming call again within a set time as in the terminal designation function. Is executed for the first time, it is possible to more reliably prevent the control mode from being erroneously executed by a wrong telephone or the like. At that time, the answering machine 7
An announcement such as "Execution of the control mode" may be made by using the automatic response function.

In both the first and second embodiments, the set number is set to two so that the mode is switched to the terminal designation mode when the number of intermittent calls is detected once and the line is disconnected. However, for example, the set number of times is set to three times, and the mode is switched to the terminal designation mode when the number of intermittent call signals is less than three times, that is, when one or two times are detected and the line is disconnected. You can also.

In both the first and second embodiments, the time period during which the terminal can be switched to the terminal designation mode can be arbitrarily set. For example, 10:00 pm to 1 pm
A control circuit 5, a timer built in the control circuit 5, display means and setting means (not shown) so that a time zone can be freely limited as in 1:00, and only the parent device or a specific child device can be designated and called. This can be performed using a switch or the like.
As described above, if the mode can be switched to the terminal designation mode only in the time zone such as late at night, there is practically no case where a call is designated by mistake. Note that the time zone can be set arbitrarily in other control modes as well.

In the first and second embodiments, the notification by ringing or the like is started when the number of intermittently detected call signals is equal to or greater than a set number, and the additional function is performed when the line disconnection is detected with less than the set number. `` Switch to control mode '' or `` Information such as ringing starts when the number of interrupted calls detected is greater than or equal to the set number of times, and when a line disconnection is detected with less than the set number of times, it is set for each number of additional functions among multiple additional functions It switches to a control mode that performs an additional function that has been performed, '' but this starts `` notification by ringing when the number of intermittently detected call signals exceeds the set number of times,
Switch to control mode to perform additional functions when line disconnection is detected below the set number of times. When a line disconnection is detected, the control mode is switched to a control mode for performing the additional function set for each number of interruptions among the plurality of additional functions, '' and it is clear that the equivalent technology is included. is there.

[0039]

As described above, according to the present invention, an external telephone can be used to remotely designate a desired terminal from among the base unit or a plurality of slave units provided in the base unit constituting the telephone terminal device. The user can listen to the message by the automatic response by stopping the first call before the intermittent number reaches the predetermined number and making the second call within the predetermined time. If a message indicating the remote control procedure is registered in advance, such as that the user needs to enter a personal identification number within a predetermined time when specifying the calling of the slave unit, the remote telephone can be used in accordance with this message. The operation (input operation of the designated terminal number (= password )) is facilitated, and any terminal can be called by this remote operation, so that it is possible to talk with any other party. Further, according to the present invention, the terminal designated by the designated terminal number out of the parent device or the plurality of child devices is called by ringing or the like, so that a person near the undesignated terminal is troubled by a ringing operation by a ringing operation. It will not be applied.
