The operation of the function selection means is also started when a function related to the telephone directory such as display of a telephone directory is operated or when a function related to a ringing melody such as selection of a ringing melody is operated.

FIG. 2 shows a data format of transfer data according to this embodiment. The data format of the transfer data has a data type code 201 at the beginning,
Finally, the data of the total number of digits of the transfer data and the checksum data 202 are added. In addition, between different items, there is a division code 203 for dividing the items.

The data type code is represented by five digits so that correctness can be determined as in the example shown in FIG. The division code 203 is, for example, “##”, and a code other than the data type code and the division code that does not exist in the transfer data is selected. It is assumed that the total digit number data is represented by, for example, three hexadecimal digits and that a DTMF signal of up to 4096 digits can be handled.

In this embodiment, the data type code indicating incoming melody data is "## 1 ##", and the data type code indicating telephone directory data is "## 2 ##". The incoming melody data is composed of two items, "song name" and "note data", and the number of data items is "2".

The telephone directory data includes "name", "reading", "phone number", "group name" and "E-MAIL address".
The number of data items is “5”.

The checksum 202 shown in FIG. 2 represents key data in hexadecimal data (“*” → E, “#” →
F), all data from the first digit to the position before the checksum 202 are added, and the result is set as the last two digits.

At the time of data reception, the DTMF signal reception processing means 57 of the PHS terminal on the receiving side performs the same calculation as described above, and judges whether the data is correct or not using the checksum 202 and the operation result. All of these operations are performed as software processing of the control unit 5.

FIG. 4 shows an operation example of the receiving terminal and the transmitting terminal. At the transmitting terminal, D
After the mode is set to the TMF signal transmission mode (step 40)
1) When transfer data is selected (step 402),
Data transfer is started by a key operation (such as pressing a transfer start key) that triggers the start of transmission at the transmitting terminal (step 403). When the transmission is completed, a message indicating the completion of the transmission is displayed on the LCD 52 (step 404).

At the receiving terminal, the user first sets the DTMF signal receiving mode (step 40).
3). The receiving process is started by the signal input (step 4).
06) When the transfer of all data is completed, the receiving terminal automatically terminates the reception (step 407),
The correctness of the received data is determined (step 408).

When it is determined that the received data is correct, the mode is shifted to a mode in which the user can confirm the received data, and after the completion, the data is stored and confirmed (step 409). Then, when the user instructs to save, storage in an appropriate area of the memory is started, and transfer is completed (step 410).

FIG. 5 is an operation flowchart of the PHS terminal when transmitting a DTMF signal. In the function selection state (step 501), when a function of transmitting a DTMF signal such as ring tone data is selected, a DTMF signal transmission mode is set (step 502).

After shifting to the DTMF signal transmission mode, data to be transmitted is selected (step 503). Since the selected data is stored in the memory in a format different from the transfer data format, necessary storage data is read out after selection and is arranged in a desired data format (step 504).

When the preparation for the start of transmission is completed, a state of waiting for a transmission start instruction is entered (step 505). The transmission start instruction is
This is performed by the operation unit 51 (for example, pressing a transfer start key).
When a key operation for starting transmission is performed, the key data is converted into a DTMF signal one digit at a time in order from the first data (step 506), and sound is output from the speaker 43 (step 507).

The process is repeated until all data has been transmitted (steps 509 and 510), but during transmission, a key of the operation unit 51 (such as a transmission interruption key) assigned as a key for instructing transmission interruption is pressed. Then, the transmission is interrupted (step 508).

At the time of the above-mentioned incoming melody transmission operation, the terminal transmits the number of digits currently being received on the LCD 52 and the DTMF signal by character display or by using a plurality of LEDs to transmit any digit out of the total number of transfer digits. The user may be notified of whether the user is present by lighting a predetermined LED. For example, when three LEDs are used, the total number of digits is divided into four. When the number of digits is 1/4 or less of the entire LED, no light is turned on. It is sufficient to light up two lights up to four, and light up three lights in three-quarters or more.

FIG. 6 shows P when receiving the melody data.
It is an operation flowchart example of an HS terminal. In the function selection state (step 601), when the user operates the operation unit 51 to select the function of receiving the incoming melody data (step 602), the mode shifts to the incoming melody data receiving mode, and the transmission circuit and the DTMF are transmitted. The signal demodulation unit 46 is activated, and the DTMF input from the microphone 44
The signal is ready to be received (step 603).

When a DTMF signal is input from the microphone 44, conversion from the DTMF signal to key data is performed for each signal, and when five digits are received (step 604), the type code is confirmed (step 604). Step 60
5).

In this embodiment, since the received data is incoming melody data, it is confirmed whether or not the type code is "## 1 ##" according to the data format shown in FIG.

If the type code is other than "## 1 ##", the received data is an error, so that an error is displayed on the LCD 52 (step 606), and it is confirmed whether to start the receiving operation again. (Step 607).

If the type code is a desired type code (## 1
##), the input data is received continuously (steps 608 and 609). The incoming melody data is composed of two items as shown in FIG. 3, so it is necessary to secure data of these two items. For that purpose, it is necessary to determine the division code. The received data is confirmed two digits at a time, and a division code "##" is searched for (step 610). When the reception of the section code is confirmed, the received data between the section code and the type code is secured as song name data (step 611).

Subsequently, note data is secured by the same method (steps 612, 613, 614, 615), and data of the total number of digits represented by three digits is secured (steps 616, 6).
17) The value obtained by adding the remaining number of digits 5 to the number of digits before the total number of digits data is compared with the total number of digits data (step 618).

If the data is different, the received data is incorrect, so a reception error is displayed on the LCD 52 (step 619). Then, the data secured so far is discarded, and the receiving operation ends.

If the data match, all the data from the first digit to the total number of digits data is added (calculated as a hexadecimal number) (step 619), and the result is received with the lower two digits subsequently. (Step 620), and compares it with the two-digit checksum data (step 621).

If the data is different, the received data is incorrect, so a reception error is displayed on the LCD 52 (step 622). Then, the data secured so far is discarded, and the receiving operation ends (step 627).

If the data match, the operation shifts to a received data confirmation operation for the user (step 623). If it is an incoming melody, the title of the song is displayed, and the melody is reproduced (step 624).

After the above operation is completed, the user is again asked whether to store the data in the memory (step 625), and if so, the music name data and musical note data are stored in appropriate areas of the memory 6 (step 626).

In the above embodiment, the operation at the time of receiving the incoming melody data has been described. However, in the case of receiving the telephone directory data, an operation of receiving five items is performed, and the name, reading, telephone number, Group name, E-MAIL
Get address data.

Further, in this embodiment, the PHS terminal has been described as an example. However, if the communication terminal is a communication terminal, the communication system and the wireless terminal are used, but whether or not the terminal is a wired terminal is not limited. .
