Description

Telephone signal conversion method of telephone {Telephone Signal Conversion Method}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for converting telephone tones, and in particular, audio and video for ring back tone signals, busy tone signals, and network busy tone signals transmitted from a called party. A method for converting into a signal.

In general, when a user dials a predetermined number, the telephone converts the signal into a digital signal and transmits it to the exchange. When the exchange applies a calling current to the called party, the called party receives a ringback tone signal, a busy signal, or a network busy signal. If a response is made to the exchange, and the hook-off signal is then transmitted to the exchange, a call path between the calling party and the receiving party is formed. At this time, the exchange transmits a ringback tone signal, a busy tone signal, or a network busy signal path from the called party to the calling party, and thus the calling party can determine the status of the called party through such a signal.

In addition, even in the case of a conventional mobile phone, when the user presses a telephone number to call, and then presses a call button or a send button, through the above process, when the base station and the wireless communication path is formed, the ringback tone signal is transmitted or In the absence of a radio channel, the busy tone is transmitted.

In the conventional phones and cellular phones, signals such as a dial tone or a ringback tone signal and a busy tone signal are all uniformly monotonous and boring, and there is a problem in that it just wastes time for transmitting and receiving signals.

Accordingly, an object of the present invention is to provide various types of signals, such as audio and video signals, to the calling party instead of uniform and monotonous ringback tone signals, busy tone signals, and network busy tone signals.

It includes more. The third step may further include checking a number of dialing times, limiting redialing to a predetermined number of dialing times, and stopping output of the audio and video signals.

On the other hand, if the signal of the called party is a ringback tone signal, the method further comprises the step of determining whether the called party (hook-off). The method may further include stopping output of the audio and video signals when the called party is hooked off.

The telephone tone conversion method according to the preferred embodiment of the present invention having the above-described configuration is a time for waiting for a call state by providing various types of audio and video signals that are more efficient and easier to hear and see instead of the monotonous and monotonous conventional tone. It is effective to reduce waste.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a telephone ring tone conversion system according to a preferred embodiment of the present invention. In Figure 1, the telephone tone conversion system according to a preferred embodiment of the present invention to the calling terminal 100, the tone converter 200, the switch (or base station) 300, and the receiving terminal 400 Consists of.

The calling terminal 100 transmits the telephone number and other information of the receiving terminal 400 to call in the form of a DTMF (Dual Tone Multi-Frequency) signal or a dialing packet (Packet), etc. It has a dialing unit 120, a telephone circuit unit 140 including a handset and a control function, and a display unit 160 for outputting audio and video signals.

The tone converter 200 detects the signal from the dialing unit 120, and preferably dial signal detection unit 220 to temporarily store the telephone number signal of the called party until the end of the call, and the A signal detection unit 280 for detecting a signal from the exchange 300, that is, a ring back tone signal, a busy tone signal, and a network busy tone signal, and an outgoing call; The storage unit 260 stores programs, data, audio / video signals, and the like of the terminal 100, and a control unit 240 for controlling all components of the tone generator.

Hereinafter, a method for converting a telephone signal tone according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

When the user inputs information such as a telephone number of the receiving terminal 400, the dialing unit 120 of the calling side is transmitted to the switch 300 through the dial signal detecting unit 220 in the form of a DTMF signal or a dialing packet. (S1), the dial signal detecting unit 220 detects the dialing signal and temporarily stores the telephone number of the called terminal (S2). At this time, the control unit 240 knows the transmission status through the dial signal detection unit 220 that detects the transmitted DTMF signal or dialing packet signal, and transmits the audio / video signal to the storage unit 260 by the display unit of the calling party terminal ( Instructions to output to the 160 (S3). The exchange 300 which transmits a signal such as a DTMF signal or a dialing packet from the dialing unit 120 checks a call state of the called terminal. At this time, the signal received from the called terminal may be a ring back tone signal and a busy signal or a network busy signal.

The signal detection unit 280 of the bee converter 200 checks the signal from the called terminal (S4). When the detected signal is a ringback tone signal, the exchange 300 receives the called terminal. A ringing tone signal is sent to the mobile station, and a hook-off is checked (S5). In this case, when the called terminal is not hooked off, the controller 240 instructs to continuously output an audio / video signal, and the signal detection unit 280 continuously receives a signal from the exchange 300. If it is detected that the case is not the signaling ring tone signal, the control unit 240 checks the number of dialing (S7), preferably if the call is terminated more than two times, if the dialing is less than two times The dial signal detection unit 220 is instructed to redial the temporarily stored called party number (S2). It will be operated in the same order as described below.

In addition, when the signal detected by the signal detecting unit 280 is a signal other than a busy signal or a network busy signal, the controller 240 checks the number of times of dialing (S7), and preferably, the number of times of dialing is two. If more than one time, the call is terminated, if less than two times, the control unit 240 instructs the storage unit 260 to continue to output the audio / video signal, and to the dial signal detection unit 220 Instructs to redial the stored phone number of the called terminal (S2).
