Next, with reference to FIG. 8 and FIG. 9, control of the mobile communication terminal device having the above configuration at the time of a missed call will be described. FIG. 8 is a flowchart of this control.

When the mobile communication terminal receives the incoming signal from the base station, the caller number detecting means 751 detects the telephone number of the caller (step 8a). Then, the incoming data storage control unit 752 associates the current date and time information sent from the clock unit 780 with the telephone number of the caller detected by the caller number detection unit 751, and stores it in the missed call data storage area 762. It is stored (step 8b).

The caller name search means 753 stores the data of the same telephone number as the telephone number stored in the missed call retransmission data storage area 763 in the telephone directory data storage area 761.
(Step 8c). If there is a corresponding telephone number, the process proceeds to step 8e. If there is no corresponding phone number, the process proceeds to step 8m (step 8d).

At step 8e, the caller name search means 75
3 reads out the name of the called party stored in the telephone directory data storage area 761 in association with the corresponding telephone number. Then, the read name is used as a caller name,
The process is stored in association with the corresponding telephone number in the missed call data storage area 762, and the process proceeds to step 8f.

In step 8f, data such as the time of the call arrival and the corresponding caller name are read from the missed call data storage area 762 and displayed on the display 771.
Move to step 8g.

In step 8g, it is monitored whether or not the user has performed a response operation to the incoming call.
If a response operation is performed, step 8
h, and if not, then to step 8j.

At step 8h, the data (time data, caller's telephone number data, and caller name data) recorded in the missed call data storage area 762 due to the incoming call are deleted, and the routine goes to step 8i to execute the normal operation. Performs the call processing of and ends.

On the other hand, in step 8j, it is monitored whether or not the incoming call has stopped. If the incoming call has stopped, the process proceeds to step 8k. If the incoming call has not stopped, the process returns to step 8g.

At step 8k, information on the date and time of the call and the name of the caller are read from the missed call data storage area 762, and this data is displayed, for example, as shown in FIG. 9A. I do.

At step 81, data on the missed call (information on the date and time of the incoming call, the telephone number of the caller, the name of the caller) is read from the missed call data storage area 762, and the missed call retransmission data storage area 763 is read. And the process ends.

At step 10c, it is determined whether or not the data of the missed call is stored in the missed call retransmission data storage area 763 (there is a missed call). Here, when the data is stored, the process proceeds to step 10e. On the other hand, if the call is not stored (there is no missed call), the process proceeds to step 10d, and a display as shown in FIG. 9C is made on the display unit 771, and the user is notified that there is no missed call. Then, in steps 10a and 10b, the pressing of the call key 772a and the missed call retransmission key 772b is monitored again.

At step 10e, it is determined whether or not the data stored in the missed call retransmission data storage area 763 is added with the data of the caller name. Here, if the data of the caller name is added, the process proceeds to step 10f, and if not, the process proceeds to step 10i.

In step 10f, the date and time of the missed call and the name of the caller are read out from the missed call retransmission data storage area 763, and displayed on the display 771, for example, as shown in FIG. Caller name).

Then, the flow shifts to step 10g, where a standby state for monitoring whether or not the user has pressed the call key 772a is established. When the call key 772a is pressed, the flow shifts to step 10h.

At step 10h, the telephone number (the telephone number of the missed caller) stored in the missed call retransmission data storage area 763 is read out, and the display 771 receives the incoming call as shown in FIG. 9B, for example. The displayed date and time and the telephone number of the caller are displayed, and the routine goes to Step 10k.

In step 10i, the date and time of the missed call and the telephone number are read from the missed call retransmission data storage area 763, and a display as shown in FIG.

Then, the flow shifts to step 10j to wait for whether the user has pressed the call key 772a. When the call key 772a is pressed, the flow shifts to step 10k.

At step 10k, the telephone number displayed on display 771 is dialed out to the base station, and
Perform outgoing call processing. On the other hand, in step 101,
It is determined whether or not a display indicating a missed call is displayed on display portion 771. Here, when the display indicating the missed call is being performed, the process proceeds to step 10h, and the call is transmitted to the caller displayed as described above. If the display indicating the missed call is not performed, the process proceeds to step 10m.

In step 10m, after receiving a dial input from the user, the input dial is transmitted to the base station, and a normal calling process is performed. As described above, the mobile communication terminal device of the digital cordless telephone device having the above-described configuration automatically transmits data having the same number as the telephone number of the caller included in the incoming signal sent from the base station when a missed call is received. Detected from the telephone directory data of the device, and detects the name corresponding to the detected telephone number. The detected name and the date and time of the incoming call are displayed on the display unit 771.

Therefore, according to the mobile communication terminal having the above configuration, when a missed call is received, it is possible to notify the user of at least the date and time of the missed call and the name of the caller. . For this reason, the user can save the trouble of looking up and recalling the caller from the caller number, and can immediately judge whether or not the return call is necessary.

In the above description of the embodiment, the case where there are a plurality of missed calls has not been described in detail, but in such a case, the latest missed calls are stored in the missed call retransmission data storage area 763. May be stored in order from the top, and displayed in order from the top by the user's operation, and selectively transmitted.
