The operation of the Internet telephone access device with the caller information processing function according to the present invention of the above-described configuration will be described with reference to the flowcharts shown in Figs.

First, the Internet phone connection device 10 is connected to the state shown in FIG. 1, and assumes an Internet phone mode by the Internet phone connection device 10. When the USB cable 16 for connection with the PC 14 is connected, the operating power is supplied from the PC 14 to the Internet telephone unit 100, and the power source port 54 is connected to the caller information processing unit 200. The operating power is applied from the power adapter 12 via the.

Here, when the USB cable 16 from the PC 14 is connected through the USB port 56, the Internet phone display LED 50 is turned on with green light, and the power adapter 54 is connected to the power port 54. When 12) is connected, the caller information mode display LED 52 emits green light under the control of the CPU 208 to indicate a power-on state.

In addition, for the PC 14 connected to the Internet telephone connection device 10 through the USB cable 16, the 'Windows 98' for the Internet telephone connection device 10 is set according to a predetermined procedure. With support, an Internet phone driver (such as a composite device, a human interface device, an audio driver) and an application program are installed.

When such an Internet phone driver and an application program are installed in the PC 14, selective use of the general phone mode or the Internet phone mode by the corresponding Internet phone connection device 10 becomes possible.

That is, while the corresponding Internet telephone connection device 10 and the general telephone 22 are kept in the call waiting state (i.e., step 300 of FIG. 5), the hook switch of the ordinary telephone 22 is turned off-hook. If no change is made (i.e., NO in step 302 of FIG. 5), when the incoming call (i.e., call) occurs to the telephone 22, (i.e., step 304 of FIG. 5), the telephone 22 is shown in FIG. The normal call processing described in step 306 of FIG.

That is, a ring signal of the general telephone 22 is generated for an incoming call from the public telephone network PSTN 26 via the subscriber line 28 connected to the subscriber line port 60. In response to the ring signal, call processing under the general telephone mode by the ordinary telephone 22 is executed.

On the other hand, when the hook switch of the telephone set 22 is switched to the off-hook state in step 302 of FIG. 5, the off-hook state is detected by the hook state detecting unit 102 and the voice processing unit ( 104 and the slick 106.

In this state, when the Internet telephone mode is not set by the operation of a specific dial button (e.g., '＃' button) from the ordinary telephone 22 (NO in step 308 of FIG. 5), the voice processing unit 104 Recognizes as the origination (that is, the call) in the normal telephone mode (YES in step 310 of FIG. 5) with respect to the general telephone 22, the general telephone 22 through the call path switch unit 108 Connection to the PSTN 26 side is maintained through the subscriber line port 60 so that the general telephone mode is executed (step 312 of FIG. 5).

On the other hand, if the operation of a specific dial button (e.g., '＃' button) is detected from the general telephone 22 in the step 308 of the figure through the DTMF decoder 110, the voice processing unit 104 switches the call path switch. The unit 108 blocks the path of the general telephone mode and transmits the setting of the internet telephone mode to the PC 14 through the USB port 56, and the slick 106 in the internet telephone mode. When the call current is supplied from the corresponding Internet phone connection device 10 is switched to the Internet phone mode.

That is, before the Internet telephone mode is set (i.e., step 314 of FIG. 5), a connection is made to a particular Internet telephone service provider with the support of an application program installed in the PC 14, and then the Internet telephone service provider is connected. The dialer is downloaded by entering specific registered identification information (ID and password).

Then, when a specific telephone number is called with the support of the downloaded dialer, the PC 14 connects the telephone number data of the call target via the dedicated data line ADSL 20 to the Internet 18. Through the Internet phone gateway (not shown) through the Internet phone gateway, the phone number data of the call target is translated to be decipherable in a normal PSTN, and the subscriber of the phone number of the call target is transferred to the PSTN accommodated. The call is transferred to the subscriber's general telephone through the PSTN.

Here, when the Internet phone mode is not executed, the slick 106 switches the path switching unit 112 to the speaker connection port 64 or the earphone microphone 62 to connect the Internet phone connection device 10. For example, 'MP3' data provided from the voice processing unit 104 is outputted, but when the Internet telephone mode is set, the path switching unit 112 is switched to the earphone microphone connection port 62 side, so that the earphone microphone. When the earphone microphone 30 is removed from the earphone microphone connection port 62, the voice processor 104 blocks the path switching unit 112 and the call path switching unit 30. Operation 108 is to be output to the general telephone (22).

Therefore, the voice signal input from the earphone microphone 30 or the general telephone 22, for example, in the state in which the call path for the call target phone number is set, is digitally converted by the voice processing unit 104 to be connected to the USB port 56. Is transmitted to the PC 14 via the USB cable 16, and the PC 14 transmits the voice data to the Internet phone gateway via the Internet 18 connected through the dedicated data line 20. Will be delivered.

Then, when the Internet phone gateway interprets the voice system suitable for the PSTN and delivers the voice system to the PSTN, the voice signal is transmitted to the call subscriber of the call target housed in the PSTN.

The voice signal from the subscriber of the call is transmitted to the Internet phone gateway through the PSTN, converted into digital data, and transmitted to the PC 14 through the Internet 18, from the PC 14 to the USB. The digital data transmitted to the USB port 56 through the cable 16 is analog-converted by the voice processing unit 104 and transferred to the earphone microphone 30 to make a call.

When an incoming call arrives to the general telephone 22 side while such an Internet telephone mode is executed (YES in step 316 of FIG. 5), the incoming signal is received by the ring signal detection unit 202 of the caller information unit 200. It is detected and delivered to the CPU 208, whereby the CPU 208 causes the caller information mode display LED 52 to light up in red light to display the call status.

In addition, when such an incoming call arrives, if caller information (CID) is additionally transmitted at the exchange side, the caller information is applied to the CPU 208 by the FSK decoder 206. Is not added (NO in step 318 of FIG. 5), the CPU 208 displays a simple incoming call on the LCD panel 40 (step 320 of FIG. 5) while the caller information is added. In step 322 of FIG. 5, the received caller information is displayed on the LCD panel 40, and the caller information and its reception date and time (i.e., with the support of the soft timer of the CPU 208) are semiconductor. Will be stored in memory.

When the call in the Internet telephone mode is terminated, the corresponding Internet telephone access device 10 returns to the call standby mode (step 324 of FIG. 5).

Meanwhile, according to the process of processing the caller information while the caller information is stored under the control of the CPU 208, the CPU 208 waits for the mode setting (step 330 of FIG. 6) while the search button 42 ) Is operated (i.e., YES in step 332 of FIG. 6), the CPU 208 reads out the caller information stored in the semiconductor memory of the built-in type and displays it on the LCD panel 40. FIG.

In this case, it is assumed that approximately 50 sender information is sequentially stored in the semiconductor memory, but if necessary, the amount of sender information stored is controlled by increasing or decreasing the capacity of the semiconductor memory, and a plurality of senders stored in the semiconductor memory are controlled. Information is displayed on the LCD panel 40 in the order of incoming call or vice versa in response to the operation of the search button 332 (step 334 in Fig. 6).

When the mode button 44 is operated while a specific caller information is displayed on the LCD panel 40 while the caller information is being searched, the CPU 208 indicates that the reception date and time of the corresponding caller information are determined. It is to be displayed on the LCD panel 40.

Then, the call button 48 is displayed in a state in which a reception date and time for the caller information are displayed by the non-operation of the mode button 44 or the operation of the mode button 44 while the search for the caller information is performed. Is operated, the CPU 208 transfers the caller information data to the DTMF encoder 204 to perform DTMF processing so that a call back to the counterpart corresponding to the caller information is performed. The recall is made possible under the execution of the normal telephone mode described above.

On the other hand, when the erase button 46 is operated in a state in which specific caller information is displayed on the LCD panel 40 by the operation of the search button 42, the CPU 208 determines that the selected caller information is the semiconductor. Will be deleted from memory.

On the other hand, the present invention is not limited to the examples of the above description and various changes and modifications can be made within the scope not departing from the technical gist and gist of the invention, for example, the telephone number of the call target from the PC (14) Of course, a direct telephone call is also assumed through another Internet connected with another PC connected to the Internet phone through the Internet phone.
