[0010]
[Problems to be solved by the invention]
When a new mobile phone is purchased, it is necessary to transfer the telephone directory data entered in the old model to the new model. At this time, we want to transfer the phonebook without adding any special hardware to the mobile phone and without incurring any communication costs. Moreover, we want to make it possible between different models. However, no one has met all of these requirements.
[0011]
That is, the above A), B), C) and D) can only be transferred between specific devices (PHS, cordless telephone, PDC portable telephone, radio selective calling receiver, etc.). In the above B), a fee is charged using a communication line. In the above D), a special cable for connecting to a personal computer is required.
[0012]
In the present invention, in order to solve this problem, telephone directory data is transmitted by sound using a speaker and a microphone of an ordinary telephone. As a result, it is possible to transfer telephone books between different models, such as a telephone book transfer from a PHS to a portable telephone (PDC, CDMA, etc.) and a wired telephone to a PHS. However, this also has the following problems.
[0013]
The sound has a lot of ambient noise, and I want to make it less susceptible to this. In addition, adoption of a new transmission mode that requires protection against errors due to noise is slow in DTMF, which requires new additional hardware. If a new modem is prepared, it is expensive, and it can be easily copied with the required sound at the mounting location (security is difficult)
You do not know what and how much you are transferring.For example, when transferring secret data, there is no secret function on the receiving side. Is larger than the storage amount on the receiving side, the user wants to keep the received data.

BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows a block diagram in which the present invention is applied to a wired telephone. A storage unit 1 stores data such as telephone directory data and a password. Reference numeral 2 denotes a CPU which processes telephone operations and the like from the user together with the display device 80, the key input device 81, and the like, and performs conversion of telephone directory data into DTMF data, transmission and identification of a password, and the like in the present invention. A DTMF generator 3 converts data from the CPU into a sound signal. Reference numeral 31 denotes a switch, which is instructed by the CPU, to switch between a telephone voice signal and a DTMF sound signal to the amplifier 32. Reference numeral 33 denotes a switch, which is instructed by the CPU, to switch output sound to any one of the earpiece 51 of the handset 5, the speaker 52 of the speakerphone, and the earphone jack 53. Numeral 34 denotes a power amplifier circuit for a speaker, which amplifies a sound signal in order to generate a sufficient volume during a speakerphone.
[0020]
Reference numeral 55 denotes a transmission microphone of the handset 5, reference numeral 56 denotes a microphone of a speakerphone, and reference numeral 57 denotes a microphone jack to which a sound signal is input. A switch 43 selects one of the above in accordance with an instruction from the CPU and inputs it to the amplifier 42. A switch 41 switches a sound signal to a sound circuit or a DTMF receiver according to an instruction from the CPU. A DTMF receiver 4 converts a sound signal into DTMF data for the CPU. The converted data is passed to CPU 2 and converted from DTMF data to telephone directory data.
[0021]
Reference numeral 6 denotes an oscillator, which oscillates a frequency reference for generating a sound of the DTMF generator or the DTMF receiver or determining the sound.
[0022]
Reference numeral 71 denotes an audio circuit, and reference numeral 72 denotes a communication circuit, which is a two-wire / four-wire conversion speech network of a wired telephone, and is connected to a line 73.
[0023]
For use in normal telephone communication, the DTMF generator is connected to a communication circuit for dialing out by tone signal. The DTMF receiver is provided for performing remote control of an answering machine (not shown) or the like, and selects a DTMF sound from a line and transmits it to the CPU.
[0024]
An operation of transferring a telephone directory in the telephone having the above configuration will be described. The above configuration is both an output device and an input device. There are two such devices, one of which has already entered telephone directory data on the current telephone. Hereinafter, this is referred to as an “output device”. The other is for transferring data to a telephone directory with a newly introduced telephone, and is hereinafter referred to as an "input device".
[0025]
When the user sets the output device to the telephone directory output mode by key operation, the CPU 2 displays the telephone directory data amount (the number of registered items) in the storage unit 1 on the LCD display 80 and stands by. On the other hand, when the user sets the input device to the telephone directory input mode by operating a key, the CPU 2 'displays the memory capacity (the number of telephone directory entries that can be registered) on the LCD display 80' and waits. This memory amount display is to indicate in advance whether or not all data can reach the input device side by transmission.
[0026]
Assuming that the user specifies to transfer telephone directory data using the handset, the switches 31 are respectively connected to the DTMF generator 3 side, 33 is the earpiece 51 of the handset, and 43 ′ is the user. The microphones 55 'to 41' of the handset are connected to the DTMF receiver 4 'side as specified. FIG. 2 shows this state by extracting portions related to the output device and the input device. The operation will be described below in accordance with this.
[0027]
When the start of transmission is designated by the output device, the CPU 2 first reads out the personal identification number from the storage unit 1 and encrypts and transmits it. That is, if the result of encrypting the read password is, for example, “1234”, the CPU 2 interprets this as “8250, 8251, 8252, 8253” of the shift JIS code. Here, the 16-bit code is represented by four digits, and the corresponding DTMF is generated in a row.
[0028]
For example, “A” is a shift JIS code of 889F, and is converted to 889C by the correspondence conversion table (FIG. 3). Referring to this, the above “1234” is converted to “825D, 8251, 8252, 8253” and sent to the DTMF generator 3. The DTMF generator 3 generates each of them as a DTMF tone, and generates sound through the amplifier 32 and the speaker 51. This sound is converted into a sound signal by the microphone 55 'of the input device, and input to the DTMF receiver 4' via the amplifier 42 '. The DTMF receiver 4 ′ receives the sound signal and outputs “825D, 8251, 8252, 8253” to the CPU 2 ′. The CPU 2 'performs reverse conversion of this data with reference to the correspondence conversion table and decodes "8250, 8251, 8252, 8253", that is, "1234".
[0029]
The CPU 2 ′ returns the password to the original password in the password comparison test 25 ′, and receives the following transfer signal when the password is the same as the password of the transmitting device, which is input by the user in advance to the input device. If not, "PIN code error" is displayed and the transfer is stopped. The password confirmation operation is performed to prevent a person other than the authorized user from easily reading the telephone directory by using the transfer function.
[0030]
Since the output device does not know the result of the password comparison, the output device continues to output the contents of the telephone directory. If the input device succeeds in comparing the personal identification numbers, the input device accepts the data and records it in the telephone directory. That is, the contents of the telephone directory are sent in a CSV format, and the header is "last name, first name, telephone number, mobile number, FAX number, secret, remarks crlf", and the data is "Aoki, Yuko, 0123-45-6789, 030-12". -34567, 0123-45-6780, 1crlf "," ... ". . . Is transmitted.
[0031]
In this transmission, the shift JIS code “90A92c96BC...... 0d0a”, “90C2 96D8 2c............ ”“ 90 # 2 96A8 2 #........ DAD0 ”and“ ... ”and transmitted as sound. While each piece of information is being output, a numerical value indicating the number of data being transmitted is displayed on the LCD display.
[0032]
The input device receives the DTMF sound by the DTMF receiver, decodes the DTMF sound by the CPU, and outputs "Heading name, first name, telephone number, mobile number, FAX number, secret, remarks crlf" as header and "Aoki, Yuko, 0123-45-6789" as data. , 030-12-34567, 0123-45-6780, 1 crlf "," ... ". . . And store it in the phonebook. At this time, for example, if the corresponding item “secret” is not supported by the telephone directory on the input device side, this is displayed and the user's judgment is requested. If no judgment is input before the receiving memory becomes full, this item is discarded without being stored. Judgment is selected from “choosing one, discarding two, storing in remarks, and stopping transfer” as options displayed on the LCD display.
[0033]
Eventually, when all the telephone directory data has been output, the output side informs the input device side of the completion by transmitting a blank line (line of only crlf) 10 times, and ends the telephone directory transfer mode. . The input device receiving this also terminates the telephone directory transfer mode, displays "reception complete" on the LCD display, and outputs a "beep" sound to the ringer 54 '.
[0034]
If the "comparison mode" for confirming the reliability of the transmission result is set on the output device side, after transmitting five blank lines instead of ten blank lines at the end of transmission, the transmitting side transmits data again. To start. The receiving side compares this with the data recorded in the telephone directory for the first time, and displays on the LCD display whether or not there is an error.
[0035]
After the data transmission, if "overwrite mode" is set on the input side, the telephone directory data on the input side is ignored, and the telephone directory is transmitted assuming that the telephone directory is empty. This facilitates retransmission when an error occurs.
[0036]
Monitor the storage capacity of the input device that receives the phone book data transmitted from the output device, and if it is detected that storing the currently received phone book data exceeds the amount of memory, the input device will transmit and store the data The transmission is terminated, ignoring the subsequent data, and the LCD display indicates "insufficient data capacity", and outputs a beep sound to the ringer 54 '.
[0037]
In the example where the handset is used for sound transmission as described above, the interval between the handset and the handset is often different between the two telephones, which is not suitable for two-way sound transmission. ing. Also, when a speakerphone is used, the transmission sound and the reception sound cannot be distinguished, and the operation is performed by one-way transmission. However, transmission can be performed while performing handshaking at the time of data transmission in order to increase reliability. In this case, in consideration of the difference in the shape of the telephone, connection using an earphone microphone or cable connection using an earphone jack or a microphone jack is appropriate.
[0038]
FIG. 4 shows an example of a cable circuit when the cable connection is used. The output side constitutes a differential output, which is terminated with a resistor, cut in direct current, and further provided with a series resistor for impedance matching and connected to a microphone terminal.
[0039]
However, since some telephones do not have an earphone microphone terminal, sound transmission in one direction is general.
[0040]
In the above example, a wired telephone connected to a line is shown, but the same applies to a mobile telephone connected wirelessly.
[0041]
Further, by changing the frequency of the DTMF, it is possible to use a frequency different from that of the normal DTMF, and it is also possible to prevent the DTMF sound from being received from the surrounding telephone when dialing out.
[0042]
Also, in order to transmit and receive data by sound, text-to-speech conversion can be performed as a sound signal generation unit, and voice recognition technology can be used as a sound signal reception determination unit.
[0043]
Further, in order to detect or correct a transmission error due to noise, data can be transmitted twice and an error can be detected. It is also possible to transmit three times and determine the received data by majority decision. In the case of transmission by DTMF, since data transmission takes time, it is desirable to reduce the number of times in practical use.
[0044]
In the above embodiment, the voice circuit and the DTMF generator are switched and used. However, in the operation of the present invention, since the communication circuit is not used when transferring the telephone directory, the voice circuit does not operate. May be simultaneously applied (for example, added by an addition amplifier) to a pre-output amplifier. Even if the DTMF signal is applied to the communication circuit, there is no problem because the communication line is not used. Further, the DTMF receiver input may be configured to be connected to the audio circuit or the communication circuit.
[0045]
In the above description, the DTMF is used for the sound signal, but a modem signal can be used for higher-speed transmission. In this case, a modulator may be provided instead of the DTMF generator 3 and a demodulator may be provided instead of the DTMF receiver 4 shown in FIG. Recently, a DTMF generator receiver can also perform modem signal processing using a digital signal processor (DSP), and can replace and use modem processing as a DSP program instead of DTMF processing. In the case of the present invention, since no line is used in particular, only the modem signal processing can be performed without performing the processing required for communication, and the DSP processing amount can be reduced.
[0046]
Since the telephone device of the present invention is provided with a device for generating / inputting sound, it is not necessary to add new hardware to transfer telephone directory data through sound. Therefore, the telephone directory data is emitted as a sound from the earpiece, input by a microphone and decoded to obtain telephone directory data. In addition, by using the earphone microphone jack and the cable, transmission by a sound signal of a telephone directory can be performed without performing electro-acoustic conversion. At this time, it is desirable to use off-the-shelf hardware / software for the sound source / decoding device, and it is possible to use a DTMF generator receiver or a modem for transmitting and receiving a caller ID.
[0047]
With regard to security, the security code that was previously used by the sender is input to the receiver, and transmission is accepted only when the password matches at the beginning of transmission, thereby preventing unauthorized copying of data by means within the normal range. be able to.
[0048]
Data reliability is improved by transmitting multiple times and checking for coincidence. The current status is displayed on the display, and if there is no corresponding item on the receiving side, the user is inquired.
[0049]
By selecting and using a plurality of correspondence tables of data and sound signals, for example, it is possible to selectively receive even if the correspondence differs for each maker. In addition, when the memory becomes full on the receiving side due to the difference in the data storage amount, the reception is stopped, so that the already received data is not wasted.
[0050]
【The invention's effect】
As described above, according to the present invention, the telephone directory data input in the old model can be transferred to the new model, for example, when the mobile phone is replaced. In addition, telephone directory transfer can be performed without incurring communication costs. Furthermore, it becomes possible even between different models. In particular the input device may be stored in the storage unit decrypted content in accordance with the sound signals received, to sift the contents can not decode the sound signal received by the decode unit. The sound signal generator of the output device is a sound signal encoded by the sound signal encoder, the frequency of which is changed with respect to the frequency at the time of dialing and generates an encoded sound signal. Therefore, it is possible to avoid being affected by a sound signal at the time of dialing from a surrounding telephone.
[0051]
Further, according to the present invention, it is hard to receive ambient noise. In addition, transmission is possible in both directions, and handshaking can be performed. And among sound signal generation portion of one of the telephone apparatus, a mark Goka sounds signal, because the frequency to generate a modified and sound signals encoded for frequencies during dialing, ambient Can be prevented from being affected by a sound signal when a dial is transmitted from the telephone set. Second storage unit of the other telephone device may receive a decryption content according sound signal stored in the storage unit has, to sift the contents can not decoded by decoding unit sound signal received.
[0052]
Furthermore, according to the present invention, the hardware / software which has conventionally can be used, and it becomes possible only by adding a switch and the like. Particularly in the step of generating a sound signal, the frequency of the encoded audio signal is changed and encoding on the frequency at the time of dialing Runode, not affected by the sound signal at the time of dialing from the surrounding telephone It is possible to do so. In the other telephone device, stored in the storage unit decrypted content in accordance with the sound signals received, a sound signal received can sift the contents can not decoded by the decode unit.
