BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone having a function of a master unit for controlling a call from a plurality of slave units or an incoming call to a plurality of slave units.

[0002]

2. Description of the Related Art Conventionally, there is known a telephone having a plurality of cordless handsets and having a function of a master unit for controlling a call from the plurality of cordless handsets and an incoming call to these cordless handsets. A conventional telephone normally operates so as to call a corresponding handset based on a caller number notified when an incoming call is made (for example, Japanese Patent Application Laid-Open No. 5-212544). In this method, the caller ID is registered in the base unit in correspondence with the slave unit (including the base unit), and the registered caller ID is searched based on the caller number notified when an incoming call is received. If the caller number is not registered, all the slave units are called, and if the caller number is registered, the corresponding slave unit is called. In addition, when the answering machine is set, the notification that the call has been received is sent to a preset slave unit or all the slave units, regardless of who the caller is.

[0003]

However, according to the above-mentioned prior art, an incoming call of a specific slave unit (master unit) or all slave units is called at any time regardless of the arrival time, and is called during a time period when it is not desired to be called. There was a problem of being called even if there was. In addition, since a call is received even when the caller ID is not added, there is a problem that the call is called even by a nuisance call. By the way, generally, a caller usually makes a call to a specific partner (specific child device). However, the above-mentioned conventional telephone has a problem that even when it is desired to contact a specific person, another person receives the call because the main unit and all the sub units are called. Therefore, for example, when calling a specific slave unit, a caller once makes a call with the other party's telephone number, and after a line is connected, a command which is determined in advance for each slave unit is transmitted by DTMF. is there. However,
To call a specific handset (ie a specific person)
A special operation of transmitting a specific command after connecting the line has to be performed, and there is a problem that the operation is complicated. Further, in an answering machine, there is a problem that a notification to notify that an incoming call is made to a preset slave unit or to all slave units, so that another person may listen to the notification.

[0004] Therefore, the present invention can call a specific handset or all handset based on the arrival time without requesting the caller to perform any special operation, and also provides a handset corresponding to an automatic answering answering machine. It is an object of the present invention to provide a telephone which can notify only to a device.

[0005]

In order to achieve the above object, a telephone according to the first aspect of the present invention has at least a function of a master unit for controlling a call from a plurality of slave units or an incoming call to a plurality of slave units. Based on the caller ID received during the incoming call, the ringing time zone and the current time,
A specific one of the plurality of slaves is called.

Further, as a preferred embodiment, for example, as set forth in claim 2, there is provided storage means for storing a callable time zone and a callable slave unit in association with each other, and the arrival time is stored in the storage means. It is also possible to call a specific slave unit that corresponds to a callable time zone.

[0007] In a preferred embodiment, a caller ID for specifying a caller is provided, for example.
A slave unit to be called when there is an incoming call by the caller number; and a storage unit for storing the calling time zone in which the slave unit can be called up in association with the caller number, It is also possible to call a specific slave unit whose time is within the calling number stored in the storage means and the calling time zone.

In a preferred aspect, for example, when the slave unit to be called is out of the communication range as described in claim 4, after responding to the slave unit to be called by answering machine, at a predetermined timing, You may make it notify the said handset which should be called that there was an incoming call.

According to another aspect of the present invention, there is provided a telephone having at least a function of a master unit for controlling a call from a plurality of slave units or an incoming call to a plurality of slave units. An automatic answering machine responds to a call to which a caller number is added, based on a specific caller number, a call time zone, and a current time.

According to another aspect of the present invention, there is provided a telephone having at least a function of a master unit for controlling a call from a plurality of slave units or an incoming call to a plurality of slave units. A call to which no caller ID is added is handled by an automatic answering machine.

According to another aspect of the present invention, there is provided a telephone having at least a function of a master unit for controlling a call from a plurality of slave units or an incoming call to a plurality of slave units.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention
An embodiment applied to an HS master unit will be described with reference to the drawings. A. Configuration of the embodiment

A-1. FIG. 1 is a block diagram showing a configuration of a PHS master according to an embodiment of the present invention. In the figure, 10 is a transmitting / receiving unit,
It comprises a frequency conversion unit comprising a receiving unit and a transmitting unit, and a modem comprising a receiving unit and a transmitting unit. The receiving unit of the frequency conversion unit converts a signal from a slave unit (not shown) received by the antenna ANT, which is input via an antenna switch for distributing transmission / reception, into a local oscillation signal of a predetermined frequency output from the PLL synthesizer. By mixing, IF in the vicinity of 1.9 GHz band to 1 MHz band
Frequency conversion to (intermediate frequency) signal. Further, the transmission unit of the frequency conversion unit mixes a modulated wave of π / 4 shift QPSK supplied from a modem described later with a local oscillation signal of a predetermined frequency output from the PLL synthesizer,
The frequency is converted to a 1.9 GHz band, radiated from the antenna ANT via the antenna switch, and transmitted to a slave (not shown). Next, the receiving unit of the above-described modem demodulates the IF signal from the frequency converting unit, separates the IF signal into IQ data, forms a data sequence, and sends the data sequence to the communication control unit 11. Further, in the transmitting section of the modem, the data supplied from the communication control section 11

The receiving side extracts data for one slot at a predetermined timing from the received data supplied from the modem of the transmission / reception unit 10, extracts a unique word (synchronization signal) from the data, and generates a frame synchronization signal. After the descrambling of the control data section and the audio data section, the control data is transmitted to the control section 16 and the audio data is transmitted to the audio processing section 12. Further, the transmitting side adds control data and the like to the audio data supplied from the audio processing unit 12, adds scramble and the like, and then adds a unique word and the like to create transmission data for one slot. It is inserted into a predetermined slot in the frame at a predetermined timing and transmitted to the modem of the transmission / reception unit 10.

Next, the above-mentioned audio processing unit 12 is composed of a speech codec and a PCM codec. The speech codec performs compression / expansion processing of digital data, and includes a receiving side and a transmitting side. The receiving side receives the ADPCM audio signal (4 bits × 8 kHz = 3) supplied from the communication control unit 11.
2Kbps) to PCM audio signal (8 bits x 8KHz =
Decompress to 64Kbps to expand PCM
Output to codec. The transmitting side encodes the PCM audio signal supplied from the PCM codec into an ADPCM audio signal, compresses the signal, and sends the signal to the communication control unit 11. The above-described PCM codec performs an analog / digital conversion process. The receiving side converts the PCM audio signal supplied from the speech codec into an analog audio signal by D / A conversion, causes the speaker 13 to generate a sound, and transmits the signal. The side is a microphone 14 or an NCU 15 described later.
A / D conversion of the analog audio signal input from
It is converted into a CM signal and sent to the speech codec.

An NCU (network control unit) 15 is connected to a telephone line. When performing voice communication or data communication through the telephone line, processing for making and receiving calls with the line network, recovery and disconnection processing, and the like are performed. Control connection. Next, the key input unit 16 includes numeric keys for inputting the telephone number of the other party, a switch for on-hook / off-hook, a volume switch for changing audio output, and the like. The states of these keys and switches are supplied to the control unit 17. Next, the control unit 17 controls the entire apparatus according to a predetermined program. In particular, in this embodiment, NCU1
5 receives an incoming call via a telephone line, detects whether a caller ID is added, and responds to calls without a caller ID by an answering machine, and calls with the caller ID. , The transmitting and receiving unit 10 and the communication control unit 11 described above are controlled in accordance with the information registered in advance to call the corresponding slave unit. When the corresponding slave unit is not within the communication range of the master unit, the answering machine (including the automatic answering function) is used to respond. When the slave unit enters the communication range, the transmission / reception unit 10 and the communication control unit 1 are connected.
1 and notify the slave unit or NCU 1
5 to make a call to the slave via the telephone line,
You are notified. The ROM 18 stores programs executed by the control unit 17 and various parameters.

Next, the RAM 19 stores data generated under the control of the control unit 17, is used as a working area, and is composed of data such as the address and telephone number of the other party to call. A telephone directory (database) such as an address book is stored. In particular, in the present embodiment, as shown in FIG.
"Caller" that indicates which child device to call, including the parent device
Is registered. The “time” shown in the figure is data indicating that the child device including the registered parent device is to be called only when an incoming call is received during the time period. This is useful when you cannot answer the phone, for example, when you are out of the office.If you receive a call at a time other than the registered time zone, all child units including the parent unit will be called. I have. In addition, the "notification" shown in the figure, if responded by answering machine,
This flag indicates whether or not to notify the child device that the call has been received. When the flag is on, the flag is notified, and when the flag is off, the flag is not notified. The information described above can be registered at any time from the key input unit 16 described above.

More specifically, in the illustrated example, if the caller number is “03-1111-1111”, it is 9: 00 to 00:
In the time zone of 18:00, the slave unit A is called. If the slave unit A is not within the communication range of the master unit, a notification is made after responding to the answer phone. 18:00 to 9:
In the time zone of 00, the slave A and the master are called.
If the slave unit A is not within the communication range of the master unit, a notification is made after responding to the answer phone. Next, when the caller number is “0425-22-2222”, the slave unit B is read regardless of the time zone. And, if the slave unit B is not within the communication range of the master unit, the answering machine responds by telephone,
Then do not notify. Furthermore, if the caller ID is "0425
In the case of "-33-3333", the slave unit C is read regardless of the time zone. If the slave unit C is not within the communication range of the master unit, the slave unit C responds by telephone with an answering machine, and then notifies.

Next, the display section 20 is composed of a liquid crystal display for displaying various data such as an operation mode, a telephone number, a call time, and the like, and an LED for indicating ON / OFF of a switch and the like. Various data are displayed under the control of the control unit 17. Further, the timer 21 measures the current time and supplies the current time to the controller 17 at a predetermined timing.

B. Next, the operation of the PHS master according to the above-described embodiment will be described. In the following description, the operation of each unit associated with a call is the same as the operation related to a normal call, and a description thereof will be omitted.

FIG. 3 is a flowchart for explaining the operation of the PHS base unit according to the present embodiment. FIGS. 4 and 5 show the child unit by the base unit according to the difference of the caller number and the presence or absence, respectively. It is the conceptual diagram which modeled the call operation | movement. When the master unit receives an incoming call via the telephone line by the NUC 15, the master unit executes the flowchart shown in FIG. First, in step S10, it is determined whether or not a caller number has been added.
Proceed to step 12 to respond by answering machine as in the example of "no caller ID" shown in FIG. In this case, the slave units A, B, C
Do not notify. Therefore, there is no need to directly receive a call to a stranger or a caller.

Next, if the caller number has been added, the process proceeds to step S14, and it is determined whether or not the caller number is already registered in the table shown in FIG. If the caller number has not been registered, the process proceeds to step S16, and the parent device and all the child devices are called as shown in FIG. Then, in step S26, it is determined whether or not a certain number of calls have gone off-hook. If any of the calls has gone off-hook as a result of the certain number of calls, the call is started in step S28 as it is. On the other hand, if none of them goes off-hook, the process proceeds to step S30, and the answering machine responds. Further, in step S32, it is determined whether the “notification” shown in FIG. 2 is on. In this case, the process ends without notification. Therefore, in the case of a person who does not know the answering machine received while going out, or a caller, etc., the user does not need to be notified.

Next, if the caller ID is added and the caller ID is registered, the process proceeds to step S18, and the current time is set for the caller ID. It is determined whether or not "time" is entered. If not, the process proceeds to step S16 described above, and all the child devices including the parent device are called. Hereinafter, as described above, if any of them is off-hook as a result of calling a certain number of times, the telephone call is started in step S28, and if neither of them is off-hook, the answering machine responds in step S30. The notification is as described above.

Also, a caller number is added and the caller number is registered, and the current time is within the "time" set for the caller number. In this case, the process proceeds to step S22. Therefore, this also applies to the case where “time” is not registered. In step S22, the slave unit registered for the caller number is called. For example, the caller number “03-1111-1111” shown in FIG. 5 and the time is “12: 0”
In the case of "0", as shown in FIG. 2, since it is registered to call the slave unit A in the time zone of 9:00 to 18:00 with respect to the caller number, step S22 is performed.
Then, the slave unit A is called. Also, the caller ID "04
In the case of "25-33-3333", as shown in FIG. 2, it is registered that the slave C is to be called regardless of the current time, so the slave C is called in step S22.

Next, in step S24, it is determined whether or not the called sub unit is within the communication range of the master unit. If it is within the communication range, off-hook is performed in step S26 for a predetermined number of calls. If a specific caller goes off-hook as a result of calling a certain number of times,
In step S28, a call is started. On the other hand, if neither of them goes off-hook, the process proceeds to step S30,
Answer by answering machine. Further, in step S32, it is determined whether the “notification” shown in FIG. 2 is on. If "notification" is on, the process proceeds to step S34,
After notifying the called slave unit, the process ends. On the other hand, if “notification” is off, the process ends without notifying. For example, the caller number “03-11” shown in FIG.
In the case of “11-1111”, the “notification” is ON, so that the notification is made when the slave A enters the communication range, or the NCU 15 calls the slave A via the telephone line. ,Notice. Also, the caller number “04” shown in FIG.
25-33-3333 ".

As described above, in the present embodiment, the sub-unit to be called including the main unit is registered for the caller number, so that the caller can specify the specific sub-unit without performing any special operation. Can be called. In addition, since the time zone to be called is registered in addition to the caller number, the call can be received by the child device suitable for the time zone. In addition, when responding by answering machine, registration of whether or not to notify that effect is registered, so that it is possible to select whether to receive or not to receive a notification according to the situation of the handset user such as going out.

In the above embodiment, the PHS base unit is used. However, the present invention is not limited to this, and an analog telephone equipped with at least one or more wireless handsets may be used. in this case,
The answering machine notification performed when the slave unit is out of the communication range of the master unit is performed when the slave unit returns to the communication range since the slave unit cannot be called via the telephone line.

[0028]

According to the first and second aspects of the present invention,
Out of a plurality of sub units, the sub unit corresponding to the caller ID received during the specific time at the arrival time is called, so callers who can receive calls with the sub unit suitable for the time zone are special operations The advantage that a specific child device can be called without performing the above operation is obtained.

According to the third aspect of the present invention, a specific one of the plurality of handset units is called based on the caller number received during the incoming call, the calling time zone, and the current incoming call time. Therefore, there is an advantage that the terminal can be received by the child device suitable for the time zone.

According to the fourth aspect of the present invention, when the handset to be called is out of the communication range, after responding to the handset to be called by an automatic answering machine, at a predetermined timing, Since the child device to be called is notified that there is an incoming call, there is an advantage that it is possible to know that the incoming call has been made even when the user is out.

According to the fifth aspect of the present invention, among calls to which a caller number is added, an automatic answering machine responds based on a specific caller number, a calling time zone and a current time. Therefore, there is an advantage that it is possible to prevent a call from a specific party from being directly received except during a specific time period such as during sleep or going out.

According to the invention of claim 6, a call to which no caller ID is added is handled by an automatic answering machine, so that a call from an unnecessary party can be directly received. The advantage is that it can be avoided.

According to the seventh aspect of the present invention, when an automatic answer to a call to which a caller number is added is handled by an answering machine, thereafter, at a predetermined timing,
Since the slave unit corresponding to the caller number is notified that there is an incoming call, for example, even when the user is out of the office, it is possible to know that the incoming call has been received.
