[Problem that the invention seeks to solve]

However, the conventional telephone system configured as described above has the following problems.

Since it is a real-time process, the storage means 4 cannot execute its corresponding processing operations in parallel, that is, it becomes a "call" waiting process, which increases the waiting time of the user of the telephone 2 and causes an emergency. The storage device attached to the machine is inconvenient.
Because they are commonly memorized, they are treated similarly to post office boxes, and the protection of individual privacy is incomplete.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a telephone set which solves the problem of long waiting time when "calls" are concentrated and the problem of inability to protect the confidentiality of personal messages.

[Means for solving problems]

The telephone according to the present invention has one or more storage areas with calling party numbers as indicators, and each of the storage areas has a predetermined number depending on the caller who is expected to be called. and storage means for storing message information.

[Effect]

When a call is received, the message information in the storage area with the same caller number as the caller's number as an index is read out and sent to the caller.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 5. Note that the same components as those in the prior art are given the same reference numerals, and the description thereof will be omitted. Therefore, the exchange 3 according to the present invention does not include the storage means 4 of the prior art.

However, 11 is a communication line, 12 is a communication processing circuit connected to the communication line 11, and the communication processing circuit 12 is configured to input a digital signal transmitted from the calling party via the communication line 11. It has become.

Further, 13 is the telephone 1. or a handset 2, 14 a system control circuit, and 15 a key manual means for dialing the telephone number of the called party or inputting desired text message information, etc. when making a call to the called party; show. Further, 16 indicates a display means.

Here, the communication processing circuit 12 includes a signal analysis means 16 that decomposes a digital signal transmitted by the other party into text message information, voice message information, control information, etc. , a signal synthesizing means 17 for synthesizing voice message information input from the handset 13 or text message information input from the key manual means 15 with control information and transmitting the synthesized signal to the other party.

The system control circuit 14 also includes the communication processing circuit 1.
The control information is inputted from No. 2, and various peripheral circuits are controlled based on the control information. The system control circuit 14 is equipped with an absentee mode setting means (not shown) for setting when the family member goes out, and the system control circuit 14 is activated when the absentee mode setting means is activated, that is, when the family member is absent. and an at-home mode system 19 which is activated when the absentee mode setting means is not activated and when the family member is at home.

Here, the absent mode system 18 stores voice message information and text message information from the other party (calling party) in each storage area 21, 21°-. A first writing means 22 stores the number as an index and displays the caller number on the display means 16 to notify that the caller has been called; to each storage area 21, 21 . . . . - a second writing means 23 for writing message information to the
Storage area 21.21. indexed by the calling number that is the same as the calling number of the caller. . have. The stored contents read by the first successive means 25 are transmitted to the calling party by the communication processing circuit 12.

Further, the at-home mode system 19 writes each storage area 21,
21. The memory contents written in - and - are displayed on the display means 16 as text message information, the text message information is displayed as is on the display means 16, or the voice message information from the other party is output as is from the handset 13. It has an output means 27 for outputting.

The system control circuit 14 compresses the voice message information via the data compression/encoding circuit 28 at the subsequent stage and then stores the compressed data in the storage means 20, the details of which are shown in FIG.

First, in the figure, (a) indicates an audio analog signal, and (b) indicates a digitized digital value of that signal. A silent period 29 of the input voice as shown in the figure is detected by searching its data value, and unvoiced data in this period is discarded. Then, instead of that, a voiceless index data value 30, which is a pair of an index code indicating that there is no voice and a numerical value indicating the period length, is inserted at that position. After this, the audio data portion 32 of the next audio portion 31 is placed successively. In addition, in the figure, 33 indicates a called signal.

The second stage of compression is data compression encoding. The operating path will be explained with reference to FIG.

First, the audio analog signal input from the handset 13 is processed by the codec IC (mainly IO2, which converts the audio analog signal into a digital signal) in the communication processing circuit 12.
At the same time, the reverse conversion can also be performed) to convert the signal into a digital signal, which becomes a code signal for pulse code modulation. This code signal is input to a data compression encoding circuit 28, which converts pulse code modulation (PCM) data into adaptive differential pulse code modulation (PCM) data.
The data (hereinafter referred to as ADPCM) is compressed and encoded as a code. This processing achieves data compression of about 60%. Conversely, when reading the voice message information stored in the storage means 20, by operating the selection key of the key manual means 15, the compression encoding device 28 is activated after the control of the system control circuit 14. The compressed data is decompressed, converted back to the original audio analog signal by the codec IC, and then uttered from the handset 13.

FIG. 4 is a diagram showing a storage operation method for message data stored in the storage means 20 and its arrangement according to the above-described processing. The figure shows an area containing only audio data (al and
The text data only area (bl) is arranged, the audio data section 32 and the text data section 34 are assigned the same index number, and are stored in separate storage areas for audio data only and text data only. Stored.

On the other hand, the storage means 20 consists of a semiconductor memory IC for temporary storage and an external storage device for long-term storage of a large amount of data, and is constantly monitored and operated by a storage device management program. ing. In other words, a semiconductor memory device for temporary storage has a storage data capacity of
Message information that must be stored for a long period of time due to its limited storage capacity has no choice but to be saved to an external storage device. The above-mentioned management program smoothly performs the above-mentioned operations, and while storing data in a certain direction over time, checks whether the total amount of data is within a certain tolerance value. , while judging,
If even a small amount of data is exceeded, save a series of related units of data that are considered to be outdated in time to an external storage device, and record this operation record in a specific part of the external storage device. ing. If an attempt is made to input new data and the amount of data exceeds the storage capacity of the external storage device, the telephone of the present invention displays a warning of this condition on the display means 16 and stops storing new data. do. At this time, the user organizes the data in these external storage devices.

Further, as the external storage device, for example, a magnetic tape 35, a magnetic disk 36, a magnetic bubble memory 37, etc. are used.

The telephone according to the present invention is configured as described above, and its operation will be explained next.

Note that when a family member is at home and there is a call from the other party, the output means 27 of the home mode system 19 of the system control circuit 14 outputs the voice message information from the other party directly from the handset 13, Alternatively, the text message information is displayed as is on the display means 16. This point is similar to that of the prior art.

However, first, when you are away from home, use the caller's calling number as an indicator to the caller who is expected to be called.
The desired message information is stored in the storage area 21 of the storage means 20,
21. Write in −. This writing is performed by the system control circuit 1.
The second writing means 23 of No. 4 performs this.

FIG. 5 is a flow diagram showing message registration of voice and text messages and transmission and reception of service signals of the telephone according to the present invention. First, when a response or calling operation is performed, step S
1, the calling party sends a calling signal and a calling party number. On the other hand, in the telephone of the present invention, in the absent mode, if the calling party number matches the registered number in advance, and there is a corresponding number (step S2),
The first successive output means 25 reads the message information that has already been registered, and the communication processing circuit 11 transmits it to the calling party (step S3).

On the other hand, this time, the caller sends a message in response to the registered message information:
The first writing means 2 for the storage means 20 of the telephone of the present invention
2 records.

Inquiry as to whether or not to do this is made by sending a voice message of a specific sentence to the calling party in step S4, such as "Do you have something to say in response to the previous message?" In response, the calling party
In step 5, by pressing a preset key for YES or NO, a so-called recording footstand instruction signal is responded. This causes the telephone of the present invention to either record a response message from the caller or take an evasive action. Finally, when this series of operations is completed, the calling or called party hooks ON, the line loops off, and the above sequence ends. If there is no matching number in the matching operation in step S2, a pre-registered voice message with a certain sentence, such as "I'm currently out of town", is sent out in step S6, and then , In step S7, a voice message similar to that described above is issued to prompt the user to leave a message, such as, for example, "Do you have any message?" In response, the calling party utters a voice, thereby storing the message in the telephone of the present invention. The progression of these series of actions all uses "voice messages" for percussion.
The format is to proceed through the steps while confirming the user's intentions.

After the family member returns home, the second output means 26 of the at-home mode system 19 of the system control circuit 14 reads the message information from the other party stored in the storage means 20 and outputs it to the display means 16 or the handset 13. , inform the contents. As described above, different message messages can be stored for each of a plurality of callers who are expected to be called in advance, and response messages to these callers can also be stored individually.

〔Effect of the invention〕

As explained above, the telephone according to the present invention has one or more storage areas using the calling number as an index, and the storage area stores desired message information according to each caller. Since it is equipped with a storage means for storing information, the following effects can be achieved.

(1) "Call" such as in the case of an emergency such as a fire or earthquake
When calls are concentrated, in the telephone set of the present invention, since each telephone set registers and records separately, the caller can obtain message information without any waiting time.

(2) Privacy can be protected on an individual basis because message storage devices are distributed among each telephone.
