2. Description of the Related Art In recent years, with the spread of communication devices and the spread of communication networks to the general public, various communication services have been developed and provided on public telephone lines. As one of them, there is a service that notifies the calling party of the calling telephone number,
Various communication terminal devices that can receive such services have been developed.

FIG. 7 illustrates the basic operation of the calling telephone number notification service. In the figure, the ID receiving terminal corresponds to a communication terminal device on the service receiving side, and the subscriber line exchange corresponds to an exchange. The exchange, when receiving a call request from a subscriber telephone (calling side) to a terminal device for which a service contract has been made in advance, inverts the polarity of the telephone line on the called side and then transmits an ID receiving terminal activation signal. Send out. At this time, the calling signal which has been conventionally used is not sent to the called side.

[0004] In response to this, if the terminal device on the called side can receive the transmission source data, the called terminal closes the DC circuit in the terminal and receives the call, and sends out the primary response signal. When the exchange confirms this primary response signal, it transmits source data (modem signal) including the source telephone number to the called terminal device, and upon receiving this, the terminal device opens the DC circuit and opens the DC circuit. , Disconnect the line and return a reception completion signal.

In this manner, the exchange transmits the source data to the terminal device that has received the call request from the subscriber telephone, and then transmits the conventionally used call signal. Upon receiving the call signal, the called terminal device sounds a ringing tone to prompt an incoming call, and displays the calling source data of the calling side received earlier at this time on the display.

[0006] Here, when the called terminal device judges by looking at the source data, picks up the handset and receives a call, and responds, when the DC circuit is closed again, a secondary response signal is generated. Will be replied. When the exchange receives this secondary response signal, it reverses the polarity and connects the telephone line between the calling telephone and the called terminal to enable the telephone conversation (see FIG. 7). (A)-(i)). On the other hand, if the called party does not respond by judging the source data, no secondary response signal is returned and the telephone line is not connected.

[0007] According to such a service, before starting a call or the like, the called party who is the communication recipient can confirm the calling party's telephone number and the source data such as the sender. Can be refused to receive a call from a party you do not want to receive, a call for advertising, a prank call, a harassing call, and the like, and appropriate measures can be taken.

[0008]

However, even if such a service becomes possible, in a communication terminal device having only a basic function corresponding to a caller telephone number notification service, information about the caller telephone number and information about the caller is required. However, even if the sender data is received, it cannot be said that the data is being used effectively.

The present invention has been proposed in view of the above circumstances, and provides a communication terminal device capable of making a return call with a simple operation by effectively utilizing the source data received at the time of calling telephone number notification service. It is intended to be.

On the other hand, for example, when the "YES" key provided on the key operation unit 6 is operated, the automatic calling means 11 may be operated immediately to automatically call the telephone number of the caller. .

Steps 300 to 304 in FIG. 4 show the basic operation of the signal processing section 1 in this case with a flowchart. 2) Return Calling Function for Source Considering the Number of Past Receptions In the present invention, in addition to the basic functions of the return call function described above, the source information storage unit M stores the source of the call transmitted from the exchange. The telephone numbers can be sequentially stored, and the necessary telephone numbers can be read out at any time to automatically make a call.

In order to realize such a function, the transmission source information storage unit M stores the number of receptions each time the transmission telephone number notification service is received, so that the reading priority is in the order of the number of receptions. , And rearrange the data. In the signal processing unit 1, if a source search key (not shown) provided in the key operation unit 6 is operated, the telephone number stored in the source information storage unit M is sequentially scrolled to the display unit 8 or the like. When the return call key (not shown) is operated at this time, the automatic calling means 11 is operated so that the telephone number displayed on the display unit 8 can be automatically called. Has become.

Steps 400 to 404 in FIG. 5 perform rearrangement of the source data stored in the source information storage unit M in consideration of the number of receptions of the source telephone number received by the source telephone number notification service. FIG. 6 is a flowchart showing a basic operation in the case of performing the operation. FIG. 6 shows a memory map of the transmission source information storage unit M used in that case. At the addresses 1 to 5 in the memory map of FIG. 6, the telephone numbers of the caller who have been rearranged in the descending order of the number of receptions in consideration of the number of receptions are stored together with the sender data and the number of receptions. In the address 0, the telephone number of the most recently received caller is stored, thereby enabling automatic calling to the latest caller.

When the present invention is implemented in such an aspect, immediately after receiving the calling telephone number notification service and terminating the communication, the telephone number of the most recently received calling source is displayed on the display unit 8. If you operate the return call key at that point, you can automatically call the most recently received caller's telephone number, and if you operate the search key, the call will be placed in the The original telephone number is sequentially scrolled and displayed on the display unit 8, so that the display unit 8
