It is a circuit for converting into a predetermined data format and outputting in synchronization with a synchronization signal of the data format, and outputs the converted data to the transmitting unit 59. Transmission signal processing unit 5
In particular, when the response instruction command, which is the designated code, is fetched, the process 8 sets the response instruction data as the designated data at the end of the message data in the transmission signal format.

The transmission unit 59 modulates the data sequentially output from the transmission signal processing unit 58, converts the data into a radio signal, and outputs the radio signal from the communication satellite transmission antenna 60.

Then, it is judged whether or not the message information being processed includes a reply instruction command for instructing the recipient to reply to the schedule (step S).
7). If it is determined that there is a response instruction command, the response instruction data is output to the message register 56 and stored in step S8.

Further, the data converted into the predetermined data format by the calling process in step S6 is the same as in step S6.
In step 8, the signal is modulated by the transmitter 59, converted into a radio signal and transmitted from the communication satellite transmission antenna 60, and the present process is completed.

Next, the operation of the above embodiment will be described.

Here, command data for instructing a reply is transmitted together with message data from the data communication terminal 1A of FIG. 1 owned by the user "AT" to the data communication terminal 1B owned by the user "KK". Data communication terminal 1B
The operation of replying the schedule data to the data communication terminal 1A according to this command will be described below.

11 and 12 show the data communication terminal 1 described above.
This shows transmission / reception processing mainly controlled by the CPU 24 after the power is turned on in A and 1B, and when the power is turned on by operating the power key 14a of the key input unit 14 (step S11), first the output is performed. It is determined whether or not a creation mode for newly creating and transmitting message data is set depending on whether or not the box read key 14e and the CALL bank key 14f are pressed (step S).
12).

In the data communication terminal 1A, the output box read key 14e and the CALL bank key 1 are used here.
By depressing 4f, it is determined that the mode is the creation mode, and then the process proceeds to the message data creation process (step S13).

That is, in the data communication terminal 1A, since the keyboard 12a as shown in FIG. 5B is displayed on the display / input unit 12, the input pen 15 is used to depress any key portion of the keyboard 12a. By doing so, message data is sequentially created.

When the creation of the message data is completed, the CALL bank memory area CB of the RAM 30 is stored depending on whether or not the CALL bank key 14f is pressed in order to select the partner to which the created message data is to be transmitted. It is determined whether or not the other party is selected from among the displayed information (step S14).

Here, when the CALL bank key 14f is pressed and it is judged that the transmission partner is selected from among those stored in the CALL bank memory area CB, the display input section 12 is used instead of the keyboard 12a. The bank data stored in the CALL bank memory area CB is sequentially scrolled and displayed by the operation of the cursor key 14h, and the bank data selected and designated by the cursor when the CALL bank key 14f is pressed again is displayed. It is determined as a transmission partner (step S15).

If it is determined in step S14 that the CALL bank key 14f has not been pressed and the transmission partner is not selected from those stored in the CALL bank memory area CB, the display / input section 12 is instructed. While the keyboard 12a is displayed, the input pen 15 is used to sequentially press arbitrary key portions to directly input the calling number CN of the transmission partner (step S16).

After the process of determining the transmission partner in step S15 or S16, whether or not a reply from the partner for the message data to be transmitted is designated, that is, whether this message data is a question message requiring a reply from the partner. It is determined whether or not (step S17).

This is because whether or not there is a pressing operation on the blinking display portion using the input pen 15 in a state in which, for example, a character "reply designation" is blinkingly displayed on the display input unit 12 after the process of determining the transmission partner. It is determined by.

In FIG. 13, the message data "set at 3 o'clock" is created in the step S13, and the bank number "01" is stored in the CALL bank memory area CB of the RAM 30 as a transmission partner in the step S4. "K.K" (call number 1111-11-
1111) is an example of the display state on the display input unit 12 immediately after the selection of "1111)".
After the above, a state in which the above-mentioned character portion AM of “response designation” is displayed in blinking is shown.

Only when it is determined that the blinking display portion AM is pressed using the input pen 15 in such a display state (step S17), the last 4 digits (value of LNK) after the created message data. , And a response instruction command (* 4) are automatically added and set (step S18).

After that, when a series of operations is completed, the created message data and command data, if added, are transferred to the output box OB of the RAM 30 and temporarily stored therein. (Step S19), transmission execution key 14c of the key input unit 14
In response to the pressing operation of (step S20), the content stored in the output box OB is encoded by the encoder unit 31,
Further, the RF transmission unit 32 modulates the signal by a predetermined modulation method to transmit and output it from the transmission antenna 33, and the transmission process is completed.

However, when a response is designated with the display contents shown in FIG. 13 and the corresponding input pen 15 is operated, the contents of the data transmitted from the data communication terminal 1A to the data communication terminal 1B. Is "11
11-11-1111 Set at 3 o'clock * 2 * 2000
0 * 4 ”.

In FIG. 1, the transmission data is transmitted from the data communication terminal 1A and is received by the nearest receiving base station 2 in the first area A1 and then operated via the public telephone line 7 and the repeater 4. When the data is transmitted to the center 5, the operation center 5 performs the operation processing shown in FIG. 4 and outputs this data to the communication satellite 6.

Further, the transmission base stations 3 and 3'receive the data by the output of the communication satellite 6 and transmit the data in the areas A1 and A2, so that the data communication existing in the second area A2 is performed. The terminal 1B can receive the call and receive the data.

Next, the process of receiving the message data by the data communication terminal 1B and the process of transmitting the reply message accompanying this will be described with reference to FIGS.

In the data communication terminal 1B, the key input unit 14
After the power is turned on by operating the power key 14a of the output box (step S11), the output box read key 14e
When it is determined that the message creation mode by pressing the CALL bank key 14f is not set (step S12), a standby state for waiting for a call is set as it is (step S21), and the ID is set.
-The decoder unit 23 intermittently drives the RF receiving unit 22 based on the frame data FD of the ID code individually assigned to the data communication terminal 1B stored in the ROM 25,
It is repeatedly executed whether or not the address code data AC that matches the ID code assigned to the own device is detected from the received signal, that is, whether there is reception for calling the own device (step S22). .

Then, when the address code data AC that matches the ID code assigned to the own device is detected and it is determined that there is reception for calling the own device, a match signal is sent to the CPU 24.
Send to In the CPU 24, the decoder unit 23 causes the message data following the address code data AC to be fetched and stored in the message memory area MM of the RAM 30 together with the time data obtained from the time-counting circuit at the time of the incoming call (step S23). After performing the notification operation by 27, the message data is displayed on the display input unit 12 (step S24).

Then, it is judged whether or not the reply instruction data is received following this message data, that is, whether or not this message data is a question message designating a reply (step S25). When the instruction data is not continued, the incoming call processing is terminated as it is, but when the reply instruction data is continued at the end of the message data, the CALL designation data (* 2
The sender of the question message is searched by searching the sender code area LN4 of the CALL bank memory area CB of the RAM 30 according to the 4-digit numerical data received after * 2) (step S26).

When the sender search is completed, it is determined whether or not there is a sender having the sender code area LN4 corresponding to the CALL bank memory area CB as the search result (step S27).

In this case, when it is judged that the corresponding sender cannot be searched, the processing for the subsequent reply is interrupted and the processing is returned from the step S21. If it is determined that the search is successful, then the sender's rank area L
It is determined whether or not the content of NK is "E", that is, whether or not the sender is of a rank that does not dare to reply (step S28).

If the content of the sender's rank area LNK is "E", the processing required for subsequent replies is also interrupted and the processing returns from step S21 to the sender's rank. When it is determined that the content of the area LNK is a rank other than "E", that is, any of "A" to "D", the items to be responded in the schedule data are determined from the flag area FLG according to the content of the rank. Then, the corresponding item of the schedule data at the time when the message data is received is extracted from the schedule data memory area SD and transferred to the output box OB (step S29), and then the data transferred to this output box OB is used as reply data. , The data communication terminal 1A
Is automatically sent to the sender who is carrying (step S
30) With the above, the processing of FIG. 11 is ended and the processing returns to the processing from step S21 again. FIG. 14 exemplifies a display state on the data communication terminal 1B when the above-mentioned reply processing is performed. Here, the message data “1111-11” transmitted from the data communication terminal 1A described in FIG. -1111 Set at 3 o'clock * 2 * 2
The display contents when "0000 * 4" are received are shown.

As shown in the figure, "* 2 * 20000" in the received data is obtained by the search processing in step S26.
From "Sender" is "AT" (call number 0000-
00-0000), that the "contents" of the message is "set at 3 o'clock", and that this message is "response specified" from the code "* 4" added to the end of the message.
The sender's "rank" is "A", and all four items in the schedule data are "location", "start (time)", "end (time)", and "content". Is set to create reply data using, and the time when there is an incoming call is "95 (year) -0
3 (Month) -01 (Sun) -11 (Hour): 15 (Minutes) "is displayed.

In response to such an incoming call, the data communication terminal 1B creates message data as a reply with the above contents by the processing of FIG. 11 described above, and automatically sends it.

In FIG. 1, the transmission data by the reply message data is transmitted from the data communication terminal 1B and is received by the nearest receiving base station 2'in the second area A2, and then the public telephone line 7'is relayed. When it is transmitted to the operation center 5 via the device 4 ', the operation center 5 performs the above-described operation processing shown in FIG.
This data is output to the communication satellite 6 again.

Further, by the output of the communication satellite 6, the transmitting base stations 3 and 3'in the areas A1 and A2 receive the data,
By transmitting the data in the area A1 and the area A2, the data communication terminal 1 existing in the first area A1
A can receive the data.

FIG. 15 exemplifies a display state on the data communication terminal 1A which receives the response message data. Here, the response message data "0000-00-0000 A city 1100" from the data communication terminal 1B is shown.
