The number notification signal S1 from the mobile phone A in FIG.
When the description is returned to the place where is transmitted, the mobile phone B performs the reception waiting process from step B2 in FIG. 2 to step A6-2 in FIG. 4, and ends the reception waiting process when the signal is received (FIG. Step A6-3). However, when the set waiting time for the signal reception elapses, a timeout occurs, the communication failure is notified to the user by the notification device 14 (steps A6-4 and A6-5 in FIG. 4), and the communication is ended as a communication failure ( Step A6-6 in FIG. 4).

Next, the processing from transmission of the abnormal reception signal S2 from the portable telephone B to the portable telephone A will be described. After receiving the number notification signal S1 and ending the reception waiting process, the normal reception confirmation process of step B3 in FIG. 2 is performed (to the normal reception confirmation process in FIG. 6). Then, it is confirmed whether or not the reception was normal (step B3-2 in FIG. 6), and if the reception was normal, the confirmation processing of the normal reception is ended (step B8-5 in FIG. 6). If the signal has not been received normally, an abnormal reception signal S2 is transmitted (step B in FIG. 6).
3-3). The communication control device 15 confirms whether the abnormal reception signal S2 has been transmitted normally (step B in FIG. 6).
3-4). If the transmission has been completed normally, the process returns to the reception waiting process (step B2 in FIG. 2).

If the transmission has not been completed normally, a retransmission determination is made (step B3-5 in FIG. 6). However, it is necessary to set a counter for retransmission determination in advance, and set the number of times of retransmission up to. As a result of the retransmission determination, if retransmission is to be performed, the abnormal signal S2 is retransmitted (step B3-3 in FIG. 6). If retransmission is not performed, a communication failure is notified to the user by the notification device 14 (step A in FIG. 4).
6-5), end as a communication failure (step A in FIG. 4)

Next, the processing from transmission of the normal reception signal S3 from the portable telephone B to the portable telephone A will be described. Returning to the case where the signal has been normally received in the normal reception confirmation processing in the mobile phone B in step B3 in FIG. 2 (step B3 in FIG. 2), it is determined whether the received signal is the communication completion signal S4. (Step B in FIG. 2)
4). Here, since it is the number notification signal S1, it is assumed that the confirmation of whether it is the communication completion signal S4 is NO, and the description will be continued.

Next, a normal reception signal is generated (step B5 in FIG. 2), and a signal transmission process is performed (step B6 in FIG. 2, FIG. 5). In the signal transmission process of FIG. 5, a signal generated in advance is transmitted (step A11-2 in FIG. 5), and it is confirmed by the central processing unit 12 whether the communication control device 15 has successfully transmitted the signal (step A11 in FIG. 5). A11-3). As a result, if the transmission has been completed normally, the signal transmission processing ends (step A11-6 in FIG. 5). However, if the transmission has not been completed normally, retransmission determination processing is performed (step A11-4 in FIG. 5), and it is determined whether retransmission is performed (step A11-5 in FIG. 5).

If retransmission is to be performed, the process returns to signal transmission (step A11-2 in FIG. 5). If retransmission is not performed, signal transmission processing is completed (step A1 in FIG. 5).
1-6). Here, it is necessary to prepare a counter in advance in order to perform the retransmission determination process, and to define how many times the retransmission should be performed.

The registration information of the received number notification signal S1 (step 13-3 in FIG. 13) is searched in the telephone number information database in the storage device 13 (step B7 in FIG. 2, FIG. 7). An example of the telephone number information database 13-1 of the storage device 13 is shown in FIG.

The search processing in the storage device 13 will be described with reference to FIG. 7. The double registration confirmation processing of a telephone number (step B7-2), the double registration confirmation processing of a registered name (step B7-3), When all the double registration confirmation processing of the number is completed normally (step B7-4), the search processing in the storage device 13 is completed normally.

Each of the confirmation processes will be described. 1
As the second confirmation processing, a telephone number double registration confirmation processing is performed (step B7-2 in FIG. 7, FIG. 8). The process searches the telephone number information database 13-1 in FIG. 13 for a telephone number already registered (step B7 in FIG. 8).
-2-2). Therefore, as a result of the search, if there is no identical number, the telephone number double registration confirmation processing is normally completed (step B7-2-5 in FIG. 8). However, when there is the same number as in the example of FIG. 13, whether to perform overwriting (step B7-2-3 in FIG. 8) or cancel the registration (step 7-2-4 in FIG. 8), Is displayed on the notification device 14 of FIG. 1 so as to select one of them, and the user is prompted to input.

Referring to the example of FIG. 13, the number notification signal S

To cancel the registration. As a second confirmation process, a double registration confirmation process of the registered name is performed (step B7- in FIG. 7).
3, FIG. 9). In this process, the telephone number information database 13-1 in FIG. 13 searches whether the registered name has already been registered (step B7-3-2 in FIG. 9). Then, as a result of the search, if the same registered name is not found, the double registration confirmation processing of the registered name is normally completed (step B7-3-7 in FIG. 9). However, if there is the same number as in the example of FIG. 13, the registered name is changed (step B7-3-2 in FIG. 9) or the existing registered name is changed (step B7-FIG. 9). 3-
4) or register with the same name (step B7-
3-5) Cancel registration (Step B7-3 in FIG. 9)
-6) so as to select one of them.
And prompt the user for input.

Referring to the example of FIG. 13, the number notification signal S
If the registration name of the registration information of No. 1 is "Suzuki", the registration name is already in the management number 5 of the telephone number information database 13-1 in FIG. Select whether to change the registration, change the existing registration name in the management number 5 of the database to "Suzuki 1", register the same name as it is, or cancel the registration. Will be.

As a third confirmation process, a shortened number double registration confirmation process is performed (step B7-4 in FIG. 7, FIG. 1).
0). In the process, the telephone number information database 13-1 in FIG. 13 searches whether the abbreviated number has already been registered (step B7-4-2 in FIG. 10). Then, as a result of the search, if there is no identical number, the double registration confirmation processing of the abbreviated number is completed normally (step B7-4-6 in FIG. 10). However, if there is the same abbreviated number as in the example of FIG. 13, whether to change the abbreviated number (step B7-
4-3) to change the existing abbreviated number (step B7-4-4 in FIG. 10) or to cancel the registration (step B7-4-5 in FIG. 10). FIG.
Is displayed on the notification device 14 to prompt the user to input.

Referring to the example of FIG. 13, the number notification signal S
If the abbreviated number of the registration information of No. 1 is "03", the number is already in the management number 3 of the telephone number information database 13-1 of FIG. Change or change the existing abbreviated number in the management number 3 of the telephone number information database 13-1 to "13".
Select whether to change to etc. or cancel registration. When the above three items have been confirmed, the normal completion of registration is displayed on the notification device 14 (step B8 in FIG. 2), and the process returns to the reception waiting state (step B2 in FIG. 2).

Next, a process from transmission of the communication completion signal S4 from the mobile phone A to the mobile phone B will be described. Returning to the description when the signal is received in the reception waiting process in the mobile phone A (step A6 in FIG. 2), it is confirmed whether the received signal is the normal reception signal S3 (step A7 in FIG. 2). If the signal is other than the normal reception signal, the central processing unit 2 determines that the communication is not performed normally,
A retransmission process is performed (step A8 in FIG. 2). The retransmission process has already been described, and will not be described.

When it is determined in step A7 of FIG. 2 that the received signal is a normal reception signal, it is confirmed whether or not another number is to be transferred from the notification device 4 to the user (step A9 in FIG. 2). The process returns to the process of searching and specifying the telephone number to be transferred from the device 3 (step A2 in FIG. 2). If the telephone number is not to be transferred any more, the central processing unit 2 generates a communication completion signal S4 and performs signal transmission processing (step A11 in FIG. 2). The signal transmission processing has already been described, and will not be described. After transmitting the signal, the process enters a reception waiting process (step A12 in FIG. 2). Regarding the reception waiting process,
The explanation is omitted because it has already been explained.

Next, the processing from transmission of the completion reception signal S5 from the mobile phone B to the mobile phone A will be described. When the mobile phone B is in a state of waiting for reception (step B2 in FIG. 2) and receives the communication completion signal S4 from the mobile phone A, a process for confirming normal reception is performed (step B3 in FIG. 2). The confirmation process of the normal reception has already been explained and is omitted.
Assume normal termination. Next, in the process of confirming whether or not the communication is a completion signal (step B4 in FIG. 2), a completion reception signal is generated (step B4 in FIG. 2), which corresponds to YES.
9) After signal transmission processing (step B1 in FIG. 2)
0), the communication is completed (step B11 in FIG. 2). The signal transmission processing has already been described, and will not be described.

Since the mobile phone A is in the reception waiting process (step A12 in FIG. 2), when the completion reception signal S5 is normally received, the communication is completed (step A1 in FIG. 2).
3). The reception waiting process has already been described, and will not be described.

In the signal transmission processing in the above embodiment (steps A11, B6, B10 in FIG. 2, FIG. 5), the number of retransmissions to be performed in the retransmission determination processing is not specified. Can be set to any numerical value. FIG.
In the reception waiting process in step A6-1, the waiting time for timeout when waiting for signal reception can be set to an arbitrary time. Although the telephone number information database 13-1 in FIG. 13 includes the information of the four items of the management number, the abbreviated number, the registered name, and the telephone number, it may include the information of other items. It is. For example, 1
It is possible to increase the number of items in the telephone number information database so that two telephone numbers of the home and the mobile telephone can be registered with one registered name. In the telephone number information database, the abbreviated number is described in two digits and the telephone number is described in nine digits. However, as long as it can be registered in the database, the number of digits of the abbreviated number and the telephone number can be any number.

The input devices 1 and 11 are composed of numbers from 0 to 9 and push buttons such as “*”, “#”, “F”, “▲”, “▼”. Is
It is also possible to use a speech recognition device. The notification devices 4 and 14 may include not only a display device but also a sound generation device. Further, the communication medium 6 is a communication cable, but may be constituted by an infrared sensor, wireless communication, or the like. In the reception waiting process (step A in FIG. 2)
6, A12, B2, FIG. 4), the communication failure end (step A6-6) means that the communication is quasi-normally terminated. However, each reception waiting process is subdivided to determine where a failure has occurred. It can be displayed on the notification device before the normal termination.
