Abstract

PURPOSE: A method for setting a self ring back tone in a portable terminal is provided to confirm a time when a ring is generated from other party's terminal and a time when the other party responds to a received call, and to supply self set audio data to a user as a ring back tone without opening a speech call during the confirmed times, so that the user can listen to the self set ring back tone. CONSTITUTION: When an originating terminal(40) requests a call setup, a network(50) generates a ring by sending a receiving signal to a receiving terminal(60). If the receiving terminal(60) supplies a signal for the ring to the network(50), the network(50) provides an alerting IND(Indication) signal to the originating terminal(40). The originating terminal(40) reproduces self set audio data during a standby time, and supplies the data to a user as a ring back tone. When a call is connected, the network(50) sends a connect ACK signal to the originating terminal(40). The originating terminal(40) opens a speech call channel to start the call with the receiving terminal(60).

Description

{SELF RING BACK TONE SETTING METHOD FOR MOBILE TERMINAL}

The present invention relates to a method for setting a ring back tone of a portable terminal, and in the outgoing call of the portable terminal, a call back channel according to a protocol with a network is controlled to carry out a ring back tone from a network. The present invention relates to a method for setting a ring back tone of a portable terminal to enable a ring back tone set by the terminal itself.

As the functions of the mobile terminal and the communication network have been improved, various services are possible, and among them, a lot of additional services related to a call, which is a basic function of the mobile terminal, are provided.

For example, a ring back tone service is provided, which uses various ringtones and caller's phone number, and receives a specific music from the network and listens to it when the call is received. . This ringback tone is a so-called "coloring" service, and is a function that allows a network to provide when a mobile terminal user selects a predetermined music or message and the other party attempts to talk to his mobile terminal.

In other words, the conventional ringback tone is a function provided by a communication network. When it is recognized that the other party's ring is ringing, the ringback tone is unconditionally opened through an internal digital signal processor (DSP). It can be said that the audio signal provided by the network can be heard until the other party answers the call, thus changing the simple tone.

Its use is spreading rapidly because it replaces simple tones with individual audio signals to give a pleasure to the sender to wait for the other party's incoming response, and the other party has a means of expressing its own personality.

However, in the prior art, the caller terminal receiving the signal indicating that the other party's ring is ringing (Alerting IND) from the network immediately opens the call and opens the audio path, so the caller unconditionally selects the unilateral ringback tone provided from the network. There is a problem that must be heard.

Because it is a ringback tone that indicates the individuality of the other party, there is a case where the contents of the caller may be provided with a feeling of rejection or aversion, and the content of being too monotonous or awkward is constantly provided. Can be colorless.

In addition, since the ringback tone function is a function that a caller can hear only when the other party registers as an additional service, when the other party does not use the corresponding service, the ringback tone function cannot but hear a general tone. In addition, the ringback tone service currently provided is limited to a mobile terminal, so when the user calls a general telephone, the ringback tone cannot be heard.

Therefore, there is a need for a method for allowing a user to set and listen to a ring back tone desired to be heard in his or her mobile terminal regardless of the type of the other party's phone and whether the user subscribes to the service.

As described above, the ring back tone service of the conventional mobile terminal is a ring back tone service that the other party requests the ring back tone service as an add-on to the network. Since the caller is provided unconditionally, the caller must listen to the content provided unconditionally without a choice, and depending on the content, there is a problem that the caller may feel rejection or boredom. In addition, when calling a mobile terminal that does not use a ringback tone service or a general landline telephone that cannot use the service, there is a problem that only a simple tone can be heard.

In view of the above problems, in the present invention, in a protocol communication between a calling party terminal and a communication network, a call call is changed at a time when a ring of the other terminal rings by changing a call opening time for an outgoing call to a case in which the other party answers the incoming call. It prevents unconditional acceptance of ringback tone that is open and provided from the network, and plays the preset music data inside the caller's mobile terminal and utilizes it as ringback tone. It is an object of the present invention to provide a method for setting a ring back tone of a portable terminal so that a ring back tone can be used regardless of the ring back tone.

The present invention for achieving the above object, the caller attempts to make a call to the other terminal; Reproducing preset audio data internally to the portable terminal and providing the user with information that the ring of the counterpart terminal rings from the network; When the other party obtains information indicating that the other party has answered the call, the reproduction of the audio data is stopped and the call is opened to communicate with the other party.

The present invention also provides a method comprising the steps of: setting internal audio data to be used as a ringback tone for telephone numbers stored in a phone book of a mobile terminal by a user; Determining the phone number and ringback tone audio data setting state of the corresponding terminal in the phone book until the user requests an arbitrary call from the terminal and acquires information from the network that the ring of the other terminal rings; ; If there is no corresponding setting according to the result of the determining step, setting a call first and continuously receiving a ringback tone or ring tone provided from the network until the other party checks the incoming call and continues to receive the call; If there is a corresponding setting according to the result of the determination step, the preset internal audio data is played without setting a call call, and when the call is connected by the other party confirming the incoming call, if the call is connected, the playback of the corresponding audio data is stopped and the call is set to make a call. Characterized in that it comprises the step of performing.

When described in detail with reference to the accompanying drawings of the present invention as described above.

1 is a simple block diagram of a portion of a mobile terminal 100 shown to explain a basic concept of the present invention. As shown in FIG. 1, a DSP 10 for processing a signal of a channel applied from a communication network and a network are provided. The MIDI chip 20, which operates independently internally without connection, and the audio path 15 for providing the audio signal decoded through the DSP 10 to the speaker 30 are briefly shown. The audio path 15 is conceptually represented as a passage, but is substantially circuitry for the received audio data to reach the speaker 30 through various audio signal processing.

First, the operation of the present invention which is different from the prior art will be described with reference to the drawings.

When a call is requested using the portable terminal, the network acquires the state of the counterpart terminal and provides the caller portable terminal with a signal according to a predetermined protocol. Among the signals used in the present invention, an alerting IND (indication) signal indicating that the ring of the other party's mobile terminal starts to ring, and a connect Ack signal indicating that the call is started in response to the incoming call. The signals can be confirmed by decoding of the DSP 10.

The present invention uses the two signals to determine when the actual call is possible and the other terminal detects the time when the ring signal is provided to block the call previously opened during that time and the internally set MIDI data It is to play through the MIDI chip 20 to provide to the user to block unwanted network-provided ringback tone received through a previously open call and to use its own MIDI music as ringback tone. .

Naturally, if a different sound source is available or various multimedia data can be played depending on the performance of the portable terminal, it can be set to be played with its own ringback tone.

That is, according to the present invention, it is possible to block the ringback tone set by the other party, and even when the other party does not use the ringback tone service, the music or the message (audio data) stored in the terminal can be used as the ringback tone. have. In addition, even if the target of the call is a general landline telephone, not a portable terminal, the ringback tone function can be used by using the present invention.

To further improve this, the ring back tone can be specialized by using a phone book set in the mobile terminal. To this end, it is necessary to improve the phone book program of the mobile terminal to set audio data for the ring back tone for each phone number. Attempts to improve the phone book of portable terminals are quite common and there will be no technical difficulties in applying them.

That is, when different ringback tones are set for each phone number recorded in the phone book of the mobile terminal, or ringback tones are grouped / collectively, when an arbitrary telephone number is called, an alerting IND signal for the corresponding phone number is made. Checks if the phone number exists in the phonebook and if the phone number exists, if there is a ringback tone, and if both the phone number and the setting exist, it receives a Connect Ack signal as described above. Afterwards, delay and provide the set ringback tone. If there is no corresponding telephone number or there is no ringback tone setting, the call can be opened and the audio path 15 can be opened to receive a network-provided ringback tone.

Figure 2 shows the signal flow of an embodiment of the present invention with respect to the members, showing the signals between the originating terminal 40, the network 50, and the receiving terminal 60 over time. Note that the receiving terminal 60 may be a general landline telephone or a portable terminal.

First, when the calling terminal 40 makes a call to the receiving terminal 60 and requests the network 50 to set up a call, the network 50 sends an incoming signal to the receiving terminal 60 to ring the ring. . When the receiving terminal 60 receives the incoming signal and rings the ring, it provides a signal for the network 50 to the calling terminal 40 as an Alerting IND signal. The caller terminal 40 decodes only the corresponding signal into the DSP so that it can be seen that the ring of the receiver terminal 60 is ringing. Note that the present invention does not open the call channel here.

Subsequently, the calling terminal 40 plays back its own audio data and provides the ringback tone to the user during the calling terminal waiting time A until the call is connected in response to the incoming call. do. As described above, the audio data may be MIDI data or multimedia data such as MP3 data.

When the call with the user of the receiving terminal 60 is connected, the network 50 that recognizes this provides a Connect Ack signal to the calling terminal 40, and decodes it through the internal DSP and receives the calling terminal 40 A call channel can be opened to make a call with the receiving terminal 60.

3 is a flowchart illustrating an embodiment of the present invention described above, which allows a user to set a different ringback tone according to the other party by using a phone book and provides a network for the other party that does not have its own ringback tone. One embodiment is shown so that ringback tones can be received.

First, the caller should set and store audio data to be used as a ringback tone in the telephone number entered in the address book (or phone book) of the terminal. You can set ringback tones for all kinds of terminal phone numbers that can be called.

When the caller calls the other party using his terminal, it checks whether the other party's phone number exists in the address book (phone book), and if so, the audio data to be used as ringback tone is set. If there is no corresponding phone number in the address book, an alerting IND signal is provided that the other party's phone is ringing, opening the call, receiving ringback tones from the network, and opening the internal audio path to the user. Then, when the other party receives the Connect Ack signal indicating that the call is available, the call is made.

If a corresponding telephone number exists in the address book and predetermined audio data is set to its own ringback tone, an internally set audio data is reproduced and provided to the user as an Alerting IND signal is provided. In this case, the call is not open, and ringback tones or tones from the network are blocked. Thereafter, when the other party receives the Connect Ack signal indicating that the other party is in a callable state, the call is opened and the call is made with the other party.

In this way, the user can enjoy the ringback tone provided by the terminal itself at no additional cost for the telephone number set by the user, and the ring tone or ringback tone provided by the network for the telephone number not set by the user can be enjoyed. You will be provided.

As described above, the present invention analyzes a protocol communication signal with a caller's mobile terminal, and detects a point of use and stop of its own ringback tone to use its own audio data as a ringback tone. Even if you're dialing an unsupported regular phone or a mobile device that doesn't use ringback tone service, you'll be able to spend time waiting with pleasure.

As described above, when the caller terminal attempts to make a call to an arbitrary counterpart terminal, the time when the counterpart terminal rings through the protocol communication between the caller terminal and the communication network is established. By checking the incoming call response, the user can provide his / her own audio data as ringback tone without opening the call for a period of time, regardless of the type of the other party's phone and whether the other party subscribes to the ringback tone service. The ringback tone provided can be heard instead of the beeping sound, and there is no additional burden, which can dramatically improve the user's communication environment.
