Description

Processing Method for Internet Call Access of Internet Phone

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internet phone, and more particularly, to a processing method for making an internet phone call connection through an Internet service provider (ISP).

In general, to make a call using an Internet phone, a call connection with the other party must first be made. This Internet call connection procedure is shown as FIG. In Fig. 1, a caller is a calling user who calls a party to make an Internet phone call, and a called user is a called user who is called by such a calling user. First, in step (100), the caller makes a long distance call or an international call to the other party using a general telephone. If the called party answers the call in step 102, the caller hangs up after requesting the other party to register on the Internet and talk to the Internet phone in step 104. The called party then hangs up after hearing the call request from the other party in step 106, and calls the ISP in step 108 to be on the Internet. In this state, the caller calls the ISP in step 110 and checks the other party waiting on the Internet. In response, if the called party picks up the receiver in response to the call in step 112, the caller calls the caller and the callee in steps 114 and 116. After the call is completed, the call ends the call between the caller and the called party in steps 118 and 120.

As described above, in order to make an internet phone call, a call requiring a registration to the Internet using a long distance / international call must be made in advance with the other party who wants to make a call. As a result, the caller would have to pay expensive long-distance / international call charges for a short time, but the callee would have to use the telephone to connect to the ISP again.

As described above, the caller bears expensive long distance / international call charges because the call is required to be registered on the Internet using a long distance / international call in advance with the other party who wants to make a call before the Internet phone call. There was a downside. In addition, the callee also had the inconvenience of having to connect to the ISP by using the telephone again. And there is a problem that takes a lot of time due to the complex call connection procedure.

Accordingly, an object of the present invention is to provide a processing method for internet call access that can be connected to the Internet call simply and to prevent additional telephone charges.

Figure 4 is an Internet call access procedure of the Internet phone according to the present invention.

According to the present invention for achieving the above object, a ring signal having a ring pattern in which a called party subscribed to a Distinctive Ringing Pattern Detection (DRPD) service has a predetermined ring pattern according to a caller's Internet phone call request is called. When a call is received from the line, the ISP dials the ISP and waits on the Internet, and if there is a call from the calling party during the waiting, it outputs a ring tone to notify the called user.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description and in the accompanying drawings to provide a more general understanding of the invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

First, referring to FIG. 2, which shows a block diagram of a typical Internet phone, the central processing unit (CPU) 200 generally controls each part of the Internet phone. The ring detector 202 is connected between the telephone lines T and R and the CPU 200, and detects a ring coming from the telephone lines T and R to detect a ring signal indicating a ring cadence. To provide. The call path unit 204 is connected between the telephone lines T and R, the dial unit 206, and a modem (modulator-demodulator) 208, and provides a call path. The dial unit 206 is connected between the call path unit 204 and the CPU 200, and under the control of the CPU 200, an MFC (Multi-Frequency Code) signal according to the dial digit is controlled through the call path unit 204. It is sent by telephone line (T, R). The modem 208 is connected between the call path unit 204 and the CPU 200, and modulates and demodulates a protocol signal and a voice signal transmitted and received to access the Internet under the control of the CPU 200. The key input unit 210 is connected to the CPU 200 and includes various function keys and numeric keys to provide key input by the user to the CPU 200. The memory unit 212 stores a program and data for the operation of the CPU 200. The external telephone I / F (Interface) unit 214 is connected to the call path unit 204 and the CPU 200, and provides an interface for connecting and using an external telephone.

In the Internet phone as described above, the present invention allows the caller to make a telephone call over the Internet simply by making a call without accessing the other party and then accessing the ISP again after a while. To do this, the called party must be subscribed to the DRPD service of the exchange. DRPD service is one of the telephone services provided by the exchange, and subscribers can apply for the telephone company separately and receive the service. This function assigns two or more telephone numbers to one subscriber telephone line, and transmits a ring having a different ring type for each telephone number, that is, a cadence, from the exchange to the subscriber telephone line. Therefore, when the calling party dials a telephone number assigned for a predetermined specific use when making a call, the exchange sends out a preset ring signal corresponding to the previous number to the called party. The called party, i.e., the called party, can distinguish the incoming call for what purpose by analyzing the ring shape based on the ring cadence when the ring signal is received.

The present invention allows a caller who wants to make an Internet call using this DRPD service first to dial a called party's phone number indicating an Internet phone call request. In response, the exchange transmits a ring signal having a ring shape preset to the called party.

3 shows an incoming call processing flow diagram according to an embodiment of the present invention for such a call. FIG. 3 illustrates a process of waiting on the Internet after dialing an ISP when a ring signal having a predetermined ring shape is received from a telephone line according to a call request from the caller, and ringing if there is a call from the caller. It shows the process of outputting and notifying the called user. The function according to the flowchart of FIG. 3 is programmed in advance in the memory unit 212 to be performed by the CPU 200 of FIG. 2.

An operation example of the present invention will now be described in detail with reference to FIG. 4, which is shown in FIG. 2 in contrast to FIG. 1, which illustrates an Internet call connection procedure of the Internet phone according to the incoming call process of FIG. 3 in the Internet phone of FIG. Hereinafter, it is assumed that the Internet phone of FIG. 2 is the called party, that is, the called party Internet phone. First, in step 400 of FIG. 4, the caller makes a long distance call or an international call to the other party using a general telephone as in the prior art. At this time, the phone number indicating the preset Internet phone call request is dialed. The caller then hangs up after waiting for a while in step 402 without waiting for the other party's response, unlike the prior art.

As described above, as the caller dials a telephone number indicating an Internet phone call request, the exchange transmits a ring signal having a ring form, that is, a cadence, to notify the called party of the Internet call. At this time, the ring detection unit 202 of the called Internet phone detects an incoming ring and notifies the CPU 200. Then, in response to this in step 300 of FIG. 3, the CPU 200 checks the form of the ring by the ring detection signal input from the ring detection unit 202 in steps 302 to 304 and performs an internet phone call. Check for the required ring type. If it is not in the ring form requesting the Internet phone call in step 316 performs a normal call service. On the other hand, in the case of a ring type for requesting an Internet phone call, the CPU 200 waits for the ring signal incoming to be terminated at step 306, and when the ring signal incoming is terminated, the ISP via the dial unit 206 at step 308. Dial. The CPU 200 waits for a call from the caller on the Internet in steps 310 to 312.

In this state, the caller calls the ISP in step 404 to check the waiting party on the Internet and make a call. In response, the CPU 200 of the called Internet phone outputs a bell sound in step 314 to notify the called user, and performs step 316.

On the other hand, if the callee who hears the ring tone picks up the receiver in step 406, the caller makes a call between the caller and the callee in steps 408 and 410. After the call is completed, the call is terminated between the caller and the called party in steps 412 and 414.

Therefore, as described above, the call procedure requiring the other party to register on the Internet and the ISP registration process for registering the party on the Internet can be collectively processed. This avoids unnecessary caller charges for the caller and eliminates the burden of calling the ISP to register with the ISP. This makes it possible to use the Internet phone more conveniently.

As described above, the present invention simplifies the procedures necessary for accessing the internet call and does not require unnecessary calls, thereby preventing additional telephone charges and making the internet call connection simple.
