Description

{Option handling method of ring back tone signal service}

The present invention relates to a dial tone conversion service method of a telephone, and more particularly, in a ringback tone signal transmitted from a called party, for overcoming a collision of different ringback tone signal conversion services generated by a separate service subscription of a calling party and a called party. The present invention relates to a method for processing a ring back tone option.

In general, when a user dials a predetermined number, the telephone converts the signal into a digital signal and transmits it to an exchange. When the exchange applies a calling current to the called party, the called party receives a ring back tone signal and busy signal. When a response is made to a switch with a busy tone signal or a network busy tone signal, and then a hook-off signal is transmitted to the exchange, the caller and the receiver receive the call. The currency path of the side is formed.

At this time, the exchange transmits a ringback tone signal, a busy tone signal or a network busy signal from the called party to the calling party, so that the calling party can grasp the state of the called party through such a signal.

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

That is, the ringback tone signal is a signal for notifying that a bilateral communication path is formed through an exchange between the calling party and the called party when the calling party attempts to talk to the called party.

In such a conventional telephone and a mobile phone, the ringback tone signals are all monotonically very dull and boring, and they also waste time in transmitting and receiving signals.

In order to overcome this problem, a service for converting the ringback tone signal and providing the same to the user, that is, the caller side, is activated, and by such a service, the user can be converted into various sound sources instead of the monotonous ringback tone signal and provided. will be.

However, such recent services (e.g., coloring services) are limited to those provided to others who attempt to make a call to a user who subscribes to the service, and the user, that is, the service subscriber himself or herself, provides a service such as a sound source selected by the user. There is a drawback to not receiving.

In order to overcome this problem, a service that allows a user to provide a sound source selected by the user for a ringback tone signal heard by the user, that is, a service subscriber, is under development.

In other words, unlike the above-described services such as coloring, the service is replaced with a sound source and a video that the user wants, so that the service is provided to the user instead of being provided to others who are trying to make a call to the user. have.

However, if such a service is provided, assuming that the calling user subscribes to the ringback tone conversion service described below, and the called user subscribes to the above-described coloring service, the calling user calls the called user. There is a problem that a situation in which the services collide with each other may occur because other sound sources designated by the different services should be provided to the calling user's telephone when making a call.

The present invention provides a user with an opportunity of service selection in a ringback tone signal transmitted from a called party, in order to overcome conflicts of different ringback tone signal conversion services caused by separate service subscriptions of the calling party and the called party. It is an object of the present invention to provide a method for processing a ring tone option such that a ringback tone conversion service determined by the user's selection is provided to a calling user's telephone.

In order to achieve the above object, a method for processing a ring back tone option according to the present invention includes: selecting a first service or a second service, which is a predetermined ringback tone conversion service, by a calling terminal user before a call attempt; Dialing a predetermined telephone number by the calling terminal user to attempt a call with a predetermined called terminal user; The called party responds with a predetermined signal by the calling party's dialing, whereby the calling terminal detects a predetermined signal transmitted from the called terminal; When the calling terminal user selects the second service, if the predetermined signal is a uniform ringback tone signal, a predetermined sound source or a video stored in the calling terminal is output, and the predetermined signal is received by the called terminal user. Outputting the predetermined sound source if the ringback tone signal is converted into a predetermined sound source; When the calling terminal user selects the first service, all of the predetermined signal is a ringback tone signal regardless of whether the predetermined signal is a uniform ringback tone signal or a ringback tone signal converted into a predetermined sound source designated by the called terminal user. Recognizing and detecting the converted to a predetermined sound source or video stored in the calling terminal and outputted; When the called party enters the call state by hooking off, the output of the ringback tone signal, which is converted into the predetermined sound source and the like, is stopped and the two-way communication channel is maintained.

Here, the calling terminal is subscribed to a first service, and the first service is a service converting a ringback tone signal into a sound source or a video designated by the calling terminal user and providing the same to the calling terminal. .

The second service may be a service for converting a ringback tone signal into a sound source designated by the called terminal user and providing the same to the calling terminal.

In addition, the caller terminal user selects the first service or the second service by operating the display unit and the dialing unit in the terminal, and the caller terminal user selection is made at each call attempt or when a specific service is selected. The service provision by the selection is maintained until this is changed.

In addition, in the ringback tone signal detected at the calling terminal, the ringback tone signal transmits a predetermined start packet before the exchange transmits the first ringback tone packet to the calling terminal, and transmits the last ringback tone packet. After that, a predetermined end packet is transmitted, and the contents of the ringback tone packet transmitted between the start packet and the end packet are a uniform ringback tone signal or a converted ringback tone signal provided to a predetermined sound source. .

Further, when the originating terminal user selects the first service, both the conventional uniform ringback tone signal and the ringback tone signal converted into a predetermined sound source, which have not undergone separate signal processing at the exchange, are ringed on the originating terminal. Recognized as a back tone signal is characterized in that the output is converted to a predetermined sound source or video stored in the calling terminal.

In addition, a predetermined sound source or the like output by the second service (or the first service) by inputting a predetermined key included in the dialing unit of the calling party terminal is stored by the first service (or the second service). It is characterized in that it is immediately changed to the output to the user.

According to the present invention as described above, an efficient ringback tone signal conversion service can be provided by avoiding collisions of different ringback tone signal conversion services generated by separate service subscriptions of the calling party and the called party by the user's selection.

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

1 is a block diagram of a system for providing a method for processing a ring back tone option according to an embodiment of the present invention.

However, the system shown in FIG. 1 represents an embodiment of a system for providing a ringback tone conversion service according to the present invention, and the method for processing a ring tone option according to the present invention is not necessarily limited thereto.

Referring to FIG. 1, it is composed of a calling party terminal 100, a beep converter 200, a base station 300, and a content provider server 400 for providing outgoing data through a data communication network.

At this time, the content provider server 400 may be an automatic response service (ARS) server, an Internet server, and the like, and outgoing data such as a sound source and a video may be transmitted from the content provider server 400 through a data communication network. It can be downloaded to 200 and updated.

Here, the outgoing data is to be the object to be converted the ringback tone signal when a ringback tone signal is transmitted from the called party is formed between the calling terminal 100 and the called terminal (not shown), Means data output to the display unit of the calling terminal 100 while the ring back tone signal is provided.

In addition, the calling terminal 100 may be a mobile terminal or a general telephone or a public telephone used in a home or office, and the wired / wireless internet function may be added to the calling terminal. 100 and the tone converter 200 may be preferably integrally formed.

The calling terminal 100 receives a telephone number and other information of a called terminal (not shown) or an ARS server serving as the content provider server 400 via a keypad (not shown). A dialing unit 160 for transmitting a DTMF (Dual Tone Multi-Frequency) signal or a dialing packet (Packet) to the base station 300, a telephone circuit unit 140 including handset and control functions, and And a display unit 120 for outputting character information or video information input through the keypad.

In addition, the user may select one of different ringback tone signal conversion services provided to the calling terminal 100 by the display unit 120 and the dialing unit 160.

That is, as described above, when the called terminal user subscribes to a ringback tone conversion service such as a coloring service, the ringback tone signal transmitted to the calling terminal 100 may be a ringback tone signal of a conventional uniform signal. In addition, since it can be provided in a state converted to a predetermined sound source, such as to prevent the collision of the sound source provided by the different ring back tone signal conversion service accordingly.

In addition, the tone converter 200 includes a vocoder 210 for analyzing or reconstructing voice, a flash memory 220 that is a nonvolatile memory, a voice, and a specific tone. For example, a tone / voice detector 230 capable of identifying a ringback tone, a busy tone, a network busy tone, and the like, and a counter storage unit 240 are provided.

In this case, the voice is generally the case that the call is connected after the hook-off state and the voice of the called user is transmitted to the calling party. In addition, when the called user's telephone is turned off, the user's telephone is disconnected. It may be given a fixed comment, such as turned off.

In addition, the vocoder 210 converts a DTMF detector 212 for detecting a DTMF signal between the content provider server 400 and the calling terminal 100, and converts an analog voice into a digital signal. An encoder 214 for converting a digital signal into an analog voice is roughly configured.

The flash memory 220 includes a DTMF activation program 222 for activating a DTMF signal detection mode, a control program 224 for controlling all components of the tone converter 200, and the content provider server 400. It includes a sound source / video storage unit 226 that stores outgoing data such as downloaded advertisements, sound sources, messages or English conversation, that is, sound sources and / or video.

In addition, the counter storage unit 240 between the receiving side and the calling side when the sound source and / or video including the transmission data, such as advertisements, sound sources, messages or English conversation stored in the flash memory 220 is an advertisement It has counter information that increases in value as the channel is formed. That is, the counter storage unit 240 increases the counter value after checking whether the advertisement is selected and the normal call is made by the control program 224 in the flash memory 220. However, such a counter storage unit 240 may not be provided when the outgoing data is not an advertisement.

The tone / voice detector 230 is a part for discriminating and detecting a person's voice or a tone of a telephone transmitted from an exchange. Looking at the function, the detection of a telephone tone is basically a ringback tone signal transmitted from an exchange, It is determined whether or not a telephone tone signal is based on a previously transmitted signal such as a busy tone signal, a hook-off signal (which may not be transmitted in some cases), and a network busy signal. In addition, as an additional judgment method, it is used in parallel with the signal detection as a method for detecting a difference between a telephone tone and a voice such as a ringback tone by software.

The software method is a voice code used in QCELP (Qualcomm Code Excited Linear Prediction) and / or Enhanced Variable Rate Coder (EVRC), which is a type of cellular phone service used in CDMA systems. The vocoder 210, which is a change / compression algorithm, is coded into a packet.

The telephone tone and / or voice packet coded by the vocoder and transmitted from the base station 300 is composed of a vector quantization value, a pitch parameter, and a format parameter. About 160 PCM samples can be obtained through the normal decoding process of the packet. In the case of the tone, energy is concentrated in a specific frequency group, and thus it can be distinguished from the voice.

In addition, speech and tone can be identified by approximating the frequency component of the received packet. In addition, since the ringback tone signal and the busy tone signal used in the telephone are repeated with a specific interruption ratio, the interruption ratio can be checked and applied to the detection of voice and tone auxiliary.

For example, in the national formal approval tone standard table, the ringback tone signal has ON time of 1 second and the OFF time of 2 seconds, and the line busy signal, which is the busy signal of subscriber, has ON / OFF time of 0.5 second each. In the case of trunk busy signal, which is a trunk line runaway signal, it has an ON time of 0.3 seconds and an OFF time of 0.2 seconds. At this time, a predetermined sound source is transmitted to the speaker during the time determined as ringback tone, and when it is determined that the ringback tone is not, the transmission of the stored sound source is stopped and normal transmission is performed.

Here, the ringback tone signal means a ringback tone signal in a national formal approval tone standard table, that is, it corresponds to a conventional uniform ringback tone signal, but as described above, the ringback tone signal is not limited thereto. When the called terminal user subscribes to a ringback tone conversion service such as a coloring service, a converted sound source may be provided instead of a ringback tone signal of a conventional flat signal.

The present invention checks the converted ringback tone signal provided to the predetermined sound source, etc., and outputs it to the calling terminal as it is, or also a predetermined ringback tone signal designated by the calling user by considering it as a conventional uniform ringback tone signal. First, decide whether to convert the output data into outgoing data.

That is, according to the present invention, one service is selectively provided by the user's option selection for the ringback tone signal conversion service that may collide with each other.

To this end, in the case of the present invention, the exchange starts transmitting the ringback tone packet after transmitting a predetermined start packet before transmitting the first ringback tone packet to the calling terminal, and after transmitting the last ringback tone packet, Characterized in that it transmits an end packet, and thus the ringback tone signal is irrespective of whether the contents of the ringback tone packet are a conventional uniform ringback tone signal or a converted ringback tone signal provided to a predetermined sound source. Can be detected.

Accordingly, the ringback tone conversion service can be selected and provided by the source terminal user's selection.

That is, when the calling terminal user selects to receive the ringback tone conversion service provided by others by the manipulation of the display unit and the dialing unit of his terminal, that is, the coloring service described above, only for the conventional uniform ringback tone signal. By attempting the conversion, a sound source or a video designated by the user is provided, and the ringback tone signal, which is converted and provided by the service of the other party, is provided with the converted sound source.

On the other hand, a ring subscribed and set up by the calling terminal user regardless of ringback tone conversion service provided by the other person by manipulating the display unit and the dialing unit of his terminal, that is, whether the ringback tone signal is converted and provided. If the user chooses to receive the back tone conversion service, the ring back tone signal divided into a predetermined start packet and an end packet is converted into a sound source or a video designated by the user and received.

Through this, collision of different ringback tone signal conversion services caused by separate service subscriptions of the calling party and the called party can be prevented in advance, and as a result, an efficient ringback tone signal conversion service can be provided.

Further, by transmitting the predetermined start packet and the end packet indicating the beginning and end of the ringback tone signal from the exchange to the calling terminal, the ringback tone signal and the predetermined message, busy signal, and the like described above are more clearly distinguished. This enables more accurate ringback tone conversion services.

2 is a flowchart illustrating a method for processing a ring tone option according to an embodiment of the present invention.

However, it is assumed that the calling terminal described below is coupled with the beep converter shown in FIG. 1, and the user of the calling terminal is subscribed to a service in which the ringback tone signal is converted into a sound source designated by the user and the like. .

Referring to Figure 1 and 2 will be described a method for processing a ring tone option according to the present invention.

First, the calling terminal user decides which ring back tone conversion service to receive before making a call. (ST 20)

As described above, the calling terminal user is in a state of subscribing to a service (hereinafter, referred to as a first service) in which a ringback tone signal is converted and provided to a sound source designated by the user.

In this case, when a user attempts to make a call and a call path is established with a called party, a predetermined ringback tone signal is transmitted, and the ringback tone signal is generally converted into a sound source designated by the user and provided.

However, at this time, a service in which the user of the called terminal is provided with a ringback tone conversion service different from the first service, that is, a sound source designated by the user is provided to another person (calling party) who attempts a call to a user who subscribes to the service ( In the case of subscribing to the second service, the first service and the second service have to collide with each other in providing the service.

Therefore, according to the present invention, before the calling terminal user who is the first service subscriber attempts to make a call, the receiving terminal user first selects which service to be provided regardless of whether the receiving terminal user is subscribed to the second service.

The selection of the service is made by the display unit and the dialing unit of the calling terminal. The service is displayed as a selection of a specific menu, and the user may select a predetermined service in the displayed state.

The user's selection may be made at every call attempt, but if a specific service is selected, the service may be maintained by the selection until the service is changed.

As described above, after the calling terminal user selects a predetermined ringback tone conversion service, the calling terminal user attempts to make a call with a predetermined called party by dialing a predetermined telephone number. (ST 21)

That is, the user attempts to make a call by dialing the phone number of the counterpart who wants to make a call by using the dialing unit of the terminal.

In this way, when there is a dialing from the user, the called party responds with a predetermined signal by the calling party's dialing, and the calling terminal detects the predetermined signal transmitted from the called party. (ST 23)

 Here, the predetermined signal detected from the calling terminal includes a ringback tone signal, a busy tone signal, a network busy signal, and a predetermined comment (the telephone is turned off, etc.).

At this time, a ringback tone signal is detected when a call path is formed between the calling party and the called party through an exchange, and when a call path is not formed, a busy tone signal, a network busy signal, or a predetermined signal is detected. do.

The present invention is applicable only when the predetermined signal is a ringback tone signal, and when a predetermined signal detected from the called party is not a ringback tone signal, that is, a busy signal or a network busy signal, a predetermined comment. In the case of retrying the call connection with the called party, the number of retries of the call connection with the called party is limited to a predetermined number of times, and if the attempt is made for a predetermined number of times, the call connection attempt is stopped.

Here, the ringback tone signal is classified into two kinds of signals according to whether the called terminal user has subscribed to the second service, which is first ringed when the called terminal user does not subscribe to the second service. The back tone signal refers to a ring back tone signal in a national formal approval tone standard table, that is, corresponds to a conventional uniform ring back tone signal. Next, when the called terminal user subscribes to the second service, Rather than a ringback tone signal of a uniform signal, a ringback tone signal converted to a predetermined sound source or the like is provided.

At this time, whether a predetermined sound source provided by the second service is output to the calling terminal is determined according to a service previously selected by the calling terminal user.

In addition, in the present invention, in the ringback tone signal detected by the calling terminal, the exchange starts transmitting the ringback tone packet after transmitting a predetermined start packet before transmitting the first ringback tone packet to the calling terminal. After the last ringback tone packet is transmitted, a predetermined end packet is transmitted.

As a result, the ringback tone signal can be detected regardless of whether the contents of the ringback tone packet are a conventional uniform ringback tone signal or a converted ringback tone signal provided to a predetermined sound source. By selecting the terminal user, the first or second service for the ringback tone conversion can be selected and provided.

Hereinafter, the caller terminal user divides the first service and the second service. (ST 23)

First, when the user selects the second service, that is, when the called terminal user selects to receive a predetermined sound source or the like by the second service provided by another user by manipulation of the display unit and the dialing unit of the user's terminal. Attempts to convert only the conventional uniform ringback tone signal and receives a sound source or video designated by the user (ST 24 and ST 25), and converts the ringback tone signal to be converted and provided by the other party's service. Will be provided (ST 26).

This is made possible by the tone / voice detector 230 of the tone changer described with reference to FIG. That is, when the tone / voice detector 230 recognizes only the conventional uniform ringback tone signal specified by the national type approval tone specification table as the ringback tone signal, the ringback tone signal converted by the second service is transmitted as it is. It is output to the terminal.

Accordingly, when the called terminal user subscribes to the second service, the ringback tone signal converted into a predetermined sound source by the service subscription may be output without undergoing any conversion inside the calling terminal. (ST 26)

However, when the called terminal user does not subscribe to the second service, the ring back tone signal is input to the calling terminal without being converted, so that it is detected as a ringback tone signal at the calling terminal, so that the user designates a predetermined number. Is converted into a sound source and a video, and output.

Next, when the user selects the first service, the user does not receive a predetermined sound source by the second service provided by the called party, and detects the sound source by recognizing it as a conventional general ringback tone signal. It will be converted into the specified sound source or video and provided. (ST 27)

This means that in the ringback tone signal detected at the calling terminal, the exchange transmits a predetermined start packet before transmitting the first ringback tone packet to the calling terminal, and then starts sending the ringback tone packet and the last ringback tone. After the packet has been transmitted, a predetermined end packet is transmitted so that all of the contents of the ringback tone packet may be a conventional uniform ringback tone signal or a converted ringback tone signal provided to a predetermined sound source. This is possible because the ring back tone signal can be recognized and detected.

As a result, when the user selects the first service, all the ringback tone signals are converted into a sound source or a video designated by the user during the time that the ringback tone signal divided into the predetermined start packet and the end packet is provided. .

Through this, collision of different ringback tone signal conversion services caused by separate service subscriptions of the calling party and the called party can be prevented in advance, and as a result, an efficient ringback tone signal conversion service can be provided.

Further, by transmitting the predetermined start packet and the end packet indicating the beginning and end of the ringback tone signal from the exchange to the calling terminal, the ringback tone signal and the predetermined message, busy signal, and the like described above are more clearly distinguished. This enables more accurate ringback tone conversion services.

Further, a conventional uniform ringback tone signal and a ringback tone signal converted by a second service to a predetermined sound source or the like on the originating terminal do not depend on the start packet and the end packet pasted before and after the ringback tone signal. If it is possible to recognize this as the same ringback tone signal, there is no need to perform separate signal processing in the exchange.

That is, in this case, both the ringback tone signal, that is, the conventional uniform ringback tone signal and the ringback tone signal converted into a predetermined sound source by a second service, etc., during the time when the ringback tone signal is directly provided on the calling terminal. Is converted into a sound source or a video designated by the user and provided.

As such, a predetermined sound source by the first service or the second service is output through the calling terminal during the ringback tone signal is provided, so that the user can overcome the free of charge during the call waiting time without any inconvenience. .

Lastly, when the called party enters a call state with the calling party as the called party hooks off, the output of the ringback tone signal that is converted into the predetermined sound source and the like is stopped, and finally the calling party and the called party receive the call. Maintain a two-way communication channel. (ST 28)

In this case, the hook-off signal may be provided to the calling terminal when the hook-off state is entered according to the type of the exchange. In the present invention, the hook-off signal is provided because a predetermined end packet indicating the end of the ringback tone is transmitted. You don't have to.

In addition, a predetermined sound source or the like output by the second service (or the first service) by inputting a predetermined key included in the dialing unit of the calling party terminal is stored by the first service (or the second service). It may be configured to be immediately changed to the output to the user.

3 is a flowchart illustrating an embodiment of a method of storing a sound source including an advertisement, a sound source, a message, or an English conversation in the calling terminal 100 in place of a ringback tone signal.

In FIG. 3, the content provider server 400 is limited to an ARS server or an Internet server.

1 and 3, first, a method of storing a sound source and / or a video in the calling terminal 100 will be described.

When a call path is formed between the ARS server and the calling terminal 100 by the ARS server or by the calling terminal 100 (S1), the control in the flash memory 220 of the tone converter 200 is performed. The program 224 activates the DTMF sensing mode of the DTMF detector 212 by executing the DTMF activation program 222.

Accordingly, the ARS server and the calling terminal 100 may communicate with each other through a DTMF command code. The ARS server sends out a sound message to the user to select one of an advertisement, a sound source, a message, or an English conversation and a sample sound source with a predetermined DTMF command code. Through the keypad of the dialing unit 160 in the side terminal 100, a DTMF command code for selecting one of a sound source, that is, an advertisement, a sound source, a message, or an English conversation, is transmitted (S2).

In response, the ARS server transmits the DTMF command code indicating the start of recording of the sound source selected by the user to the calling terminal 100, and after the recording is completed, the DTMF command code for terminating the recording of the selected sound source is transmitted. The selected sound source is stored in the sound source / video storage unit 226 of the signal converter 200 (S3).

At this time, the counter storage unit 240 stored in the EEPROM in the tone converter 200 having the number of advertisements that the user listens to is transmitted by the counter information transmission request DTMF command code of the ARS server simultaneously with the transmission of the selected sound source. It is transmitted from the calling terminal 100 to the ARS server and stored. Thereafter, the counter storage unit 240 is initialized (S5).

The DTMF command code may be implemented in various ways. For example, the DTMF command code may be "1, 2, 3, 4, 5, 6, 7, 8, 9, 0, #, *" or the like, or a frequency combination may be used. In other words, when the DTMF command code of the advertisement sound source selection request of the ARS server is "# 1", "* 1" may be used as the response DTMF command code of the calling terminal 100.

In addition, when the DTMF command code of the sound source, the message, and the English conversation selection request of the ARS server is "# 2", "* 2" may be used as the response DTMF command code of the calling terminal 100. DTMF command codes indicating the start and end of the storage of the selected sound source of the ARS server may be "# 3" and "# 4", respectively, wherein the calling party terminal 100 is the sound source selected through the DTMF command code "# 4" It can be seen that the storage of is finished.

The DTMF command code indicating the counter information request of the ARS server may be "# *", and the response DTMF command code of the calling terminal 100 may be "* # XXX". At this time, "XXX" is three-digit counter information, and the notation is decimal.

For example, if the counter information is "1", it is "001" and if it is "100", it is "100". The data structure in which the selected sound source is transmitted is in the form of "Flag1 (DTMF1) + selected sound source + Flag2 (DTMF2)". Therefore, when the originating terminal 100 detects Flag1 (DTMF1), the tone generator 200 The storage of the selected sound source is started in the sound source / video storage unit 226 in the flash memory 220, and the storage of the selected sound source is terminated when Flag2 (DTMF) is detected.

The method for storing the sound source including the above-described advertisement, sound source, message, or English conversation in the calling terminal 100, when the calling terminal 100 is available in the Internet mode, the advertisement, sound source, It may be changed to a method of storing a sound source and / or a video including a message or English conversation in the calling terminal 100. In this case, the sound source and / or video data may be downloaded through an internet browser instead of the above-described storage method using the DTMF command code or frequency combination.

In addition, the downloaded sound source and / or video data may be provided by converting a ringback tone signal and also serving as a ring tone notifying a user when a call comes to the calling terminal.

That is, a predetermined sound source desired by the user may be output in place of the ringback tone signal, or may be output as a ringtone.

4 is a flowchart illustrating an embodiment of a method for processing a ring tone option.

That is, this describes one embodiment showing a method in which a ringback tone signal, which is a response signal from a called party, is converted into a predetermined sound source and output to a calling party terminal. It is not limited to being implemented by.

In addition, it is assumed that the calling terminal described below is combined with the beep converter shown in FIG. 1, and the user of the calling terminal is subscribed to a service in which a ringback tone signal is converted into a sound source designated by the user and the like. .

Referring to FIGS. 1 and 4, when a user inputs information such as a telephone number of a called terminal (not shown), the dialing unit 160 of the calling terminal 100 transmits a DTMF command code or dialing packet. And the like to the switch 300 via the vocoder 210 in the bee converter 200 (Sa1), and the control program 224 in the flash memory 220 in the bee converter 200 sends a dialing signal. It detects and temporarily stores the telephone number of the called terminal in a predetermined position of the flash memory 220 (Sa2).

At this time, the control program 224 unit knows the transmission state through the tone / voice detector 230 in the tone converter 200, and the sound source / video storage unit 226 through the control program 224 An output instruction is made to allow the user to listen to the calling terminal 100 and the selected sound source and / or video (Sa3). In this case, when a video including the sound source is selected, the video is output to the display unit 120 in the calling terminal 100. The exchange 300 which transmits a signal such as a DTMF command code or a dialing packet from the dialing unit 160 in the calling terminal 100 checks the call state of the called terminal.

In this case, the response signal from the called terminal may be a ring back tone signal, a busy tone signal or a network busy signal, or a predetermined comment. The ring back tone signal may also be received by the called terminal user. It is classified into two kinds of signals according to whether or not it subscribes to.

This means that if the called terminal user does not subscribe to the second service, the ringback tone signal means a ringback tone signal in a national formal approval tone standard table, that is, corresponds to a conventional uniform ringback tone signal. Next, when the called terminal user subscribes to the second service, a ringback tone signal converted to a predetermined sound source is provided instead of the ringback tone signal of the conventional uniform signal.

At this time, whether a predetermined sound source provided by the second service is output to the calling terminal is determined according to a service previously selected by the calling terminal user.

In addition, in the present invention, in the ringback tone signal detected by the calling terminal, the exchange starts transmitting the ringback tone packet after transmitting a predetermined start packet before transmitting the first ringback tone packet to the calling terminal. After the last ringback tone packet is transmitted, a predetermined end packet is transmitted.

As a result, the ringback tone signal can be detected regardless of whether the contents of the ringback tone packet are a conventional uniform ringback tone signal or a converted ringback tone signal provided to a predetermined sound source. By selecting the terminal user, the first or second service for the ringback tone conversion can be selected and provided.

The signal transmitted from the called terminal is checked by the tone / voice detector 230 of the tone converter 200 (Sa4). When the detected signal is a ringback tone signal, the exchange 300 determines A ringing tone signal is sent to the called terminal, and a hook-off is checked (Sa5).

Here, when the user selects the first service, the ringback tone signal includes a ringback tone signal converted by the second service in addition to the conventional uniform ringback tone signal, and when the user selects the second service. The ringback tone signal in E c means only a conventional monotonous ring back tone signal.

At this time, when the called terminal is not hooked off, the control program unit 224 in the flash memory 220 in the beep converter 200 flashes the flash memory in the beep converter 200 to continuously output the selected sound source signal. The sound source / video storage unit 226 in 220 is instructed, and the tone / voice detector 230 in the tonal converter 200 continuously detects the signal from the exchange 300 to generate the ringback tone signal. Is detected, the control program unit 224 checks the number of dialing times (Sa7), and preferably terminates the call state if it is two or more times, and temporarily stores the called party's phone when the dialing is less than two times. Re-dial the number (Sa2).

On the other hand, when the hook-off is made in the fifth step (Sa5), a call path between the called terminal and the calling terminal 100 is formed through the telephone circuit unit 140 in the calling terminal 100, If the sound source and / or video output instead of the beeper is an advertisement, the counter value is preferably increased by “1” and stored in the counter storage unit 240 in the beeper converter 200 as the call path is formed (Sa6). . At this time, the re-dial number check can be changed by the user.

   In other words, when the caller terminal 100 attempts to make a call, the tone / voice detector 230 in the tone converter 200 is executed, and the signal transmitted from the base station 300 is the tone / voice detector 230. The sound source / video storage unit 226 in the flash memory 220 through the control program 224 in the flash memory 220 in the tone generator 200 when the tone is detected. The stored sound source and video are sent to the encoder 214 in the vocoder 210 in the signal converter 200, and the encoder 214 in the vocoder 210 sends the sound source and the video instead of the tone to the calling terminal 100. I send it to the display part in).

At this time, the tone / voice detector 230 continuously detects a radio wave transmitted from the base station 300, and outputs a sound source / video through the control program 224 when a signal other than a tone, that is, a voice signal, is detected at any moment. After that, the radio wave transmitted from the base station 300 is no longer detected and is immediately sent to the encoder 214 in the vocoder 210.

On the other hand, the communication between the beep converter 200 and the switch 300 may use a wire such as a cable, or may be performed through a wireless method used for a general mobile phone. In the case of using a wireless method, the beeper converter 200 may include a transceiver configured to transmit and receive a signal between the beeper converter 200 and the exchange 300 in a predetermined manner, for example, a radio frequency (RF) signal method. It may be further included.

In addition, the beeper converter 200 may be used integrally with the calling terminal 100, or may be used as a separate type connected to the calling terminal 100 using a port or a socket. It may be.

According to the method of processing the ring back tone option according to the present invention, the effective ring back tone signal conversion service is provided by avoiding collisions of different ring back tone signal conversion services caused by the separate service subscription of the calling party and the called party by the user's selection. The advantage is that it is provided.

In addition, by providing a conventional monotonous ringback tone signal is converted into a variety of sound sources, videos, etc. selected by the user, the user can overcome the free time during the call waiting time, and the service provider uses it as an advertisement This has the advantage of being able to generate a second profit.
