Abstract

PURPOSE: An originating call messaging method and system is provided to display an originating call message, instead of a CID(Caller ID), to a called terminal before call initiation. CONSTITUTION: A calling terminal(100) transmits a call request signal with a CID and an originating call message. An exchange(200) receives the call request signal sent from the calling terminal(100), processes the received signal so that the originating call message, instead of the CID, can be displayed at a called terminal, and relays the processed signal to the called terminal(300). The called terminal(300), if the call request signal is received, outputs a bell sound, extracts the originating call message from the received call request signal, and displays it. The called terminal(300) consists of a detection part(310), a display part(320), a voice output part(330), and a control part(340).

Description

Outgoing call messaging method and system for it {METHOD FOR MESSAGING OF ORIGINATING CALL AND SYSTEM FOR THE SAME}

The present invention relates to a communication service and a system, and particularly, in a communication environment supporting a caller ID display service, that is, a communication environment in which a calling party number is displayed on a called party's terminal before initiation of a call, a specific text message or voice message instead of the calling party's terminal number. Or it relates to an outgoing call messaging method and system for causing a video message to be displayed on the called terminal.

In general, the caller ID display service is a service for displaying a caller's terminal number (hereinafter, abbreviated as CID) to a called terminal before initiation of a call.

Since the CID display service informs the CID before the called party takes the action of accepting the call, the called party can selectively start the call after confirming the caller in advance.

The service protocol for the CID indication service is widely known. At present, a service for informing the called party of the CID and the caller's name by using the signal specification specified in the service protocol is provided.

The above CID display service was started with the purpose of preventing infringement or immoral acts of telecommunications privacy such as anonymous phone violence and indecent phone calls.

However, CID prevention services are also provided, as there is a demand from subscribers who do not want to notify CID.

The CID prevention service is a service that prevents the CID from being displayed on the called terminal by blocking the exchange in advance so that the CID is not sent to the called terminal.

However, the CID indication service or the CID prevention service cannot be fully supported for the caller who wants to make a call with the called party without informing her terminal number. In other words, a service that allows a called party to answer a call is displayed instead of the CID.

In addition, conventionally, when the CID is displayed on the called terminal, only the phrase stored in the memory of the called terminal (that is, the caller name or the nickname stored matching the displayed CID) is displayed. This does not meet the needs of individual users who demand new services.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide an outgoing call messaging method suitable for displaying an outgoing call message of a predetermined length in place of a CID before a call is initiated, and a system therefor.

It is characterized by consisting of steps.

In the above method, in the first step, a caller inputs an outgoing call message to the calling party terminal and then inputs a called party terminal number to request a call connection, and then the caller requests a call connection to the called party terminal number. As such, it is more preferable to insert the calling party information including the outgoing call message into the call request signal and transmit it to the exchange.

In the above method, in the first step, as the caller inputs another terminal number and an outgoing call message for each terminal number in advance, an outgoing call message for each terminal number is matched and stored in the calling terminal, and the caller is previously stored. After selecting a specific terminal number stored and requesting a call connection to the selected terminal number, it is more preferable to insert an outgoing call message matched with the request terminal number into the call request signal and transmit it to the exchange.

In the above method, in the second step, it is preferable that the exchange transmits the call request signal in which the calling party terminal number is replaced by the calling party message to the called terminal.

In the above method, it is more preferable that the second step is performed so that the calling party terminal number is inserted in the call request signal so that the calling party terminal number is not displayed on the called terminal.

In the above method, in the third step, it is preferable that the called terminal displays the calling terminal number inserted in the call request signal together with the calling call message.

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

1 is a view showing an outgoing call messaging system according to the present invention, Figure 2 is a view showing a detailed configuration of the calling terminal and the called terminal in the outgoing call messaging system according to the present invention.

1 and 2, the system of the present invention is applied to a communication system complying with the signal standard for the CID indication service, and is composed of the calling party terminal 100, the exchanger 200 and the called party terminal 300. . In this case, the terminals 100 and 300 have the same configuration and function, but hereinafter, the terminals 100 and 300 are divided into the calling terminal 100 and the called terminal 300.

The calling party terminal 100 inserts and transmits a CID to a call request signal sent to request a call connection, and in particular, inserts an outgoing call message into the call request signal. The outgoing call message is a message that is displayed to the called terminal 300 before call setup for the call is completed, and the message format is text (including numbers and symbols of course) or voice or The image is a combination of one or more.

The length of the outgoing call message is set within the range allowed in the CID signal format transmitted and received for the CID indication service. In particular, the outgoing call message is preferably inserted in the free area of the CID signal format.

As shown in Fig. 2, the calling party terminal 100 transmits caller information (calling party CID, caller name, etc. according to the CID indication service) to the call request signal sent to request a call connection. A program is installed to insert and send a call message. Therefore, the program is for receiving one outgoing call message by combining one or more text, voice or video, and also for storing the input outgoing call message in the internal storage.

The exchange 200 receives the call request signal sent from the calling terminal 100, processes the signal, and relays the processed signal to the called terminal 300.

Processing of the call request signal of the exchange 200 is such that the outgoing call message is displayed on the called terminal 300 instead of the CID of the calling terminal 100.

Processing examples of the call request signal by the exchange 200 will be described.

First embodiment: The call request signal is generated from the CID signal format, and the outgoing call message is inserted into the free area of the CID signal format. The exchange 200 replaces the CID inserted in the specific area of the CID signal format with the outgoing call message inserted in the free area and transmits the message to the called terminal 300.

Second embodiment: The exchange 200 maintains the outgoing call message inserted in the free area of the CID signal format and prevents the CID inserted in the specific area of the CID signal format from being displayed at the called terminal 300. The CID is deleted or the CID is hidden and transmitted to the called terminal 300. Here, as an example of a method of hiding the CID, the CID is mixed into a specific code string. In this case, if the called terminal 300 requests the CID, the CID is notified to the called terminal 300 by notifying the called terminal 300 of the code sequence used for the mixing.

Third embodiment: The CID signal format in which the CID and the outgoing call message are inserted into the different areas is maintained as it is and transmitted to the called terminal 300. Then, the inserted CID and the outgoing call message are displayed together, which is realized by internal components of the called terminal 300.

When a call request signal for requesting a call connection is received, the called party terminal 300 outputs a ringing sound and extracts an originating call message originated from the calling terminal 100 from the received call request signal. Express.

To this end, the destination terminal 300, as shown in Figure 2, is composed of a detector 310, the display unit 320, the voice output unit 330 and the control unit 340.

The detector 310 extracts an outgoing call message inserted in a specific region of the CID signal format from the received call request signal.

The display unit 320 expresses the outgoing call message extracted by the detector 310. In particular, when the called terminal is a mobile communication terminal, the display unit 320 is a display window made of LCD.

The voice output unit 330 outputs a bell sound informing of a call connection request.

The control unit 340 controls the output method of the display unit 320 according to the type of the extracted outgoing call message (the combination of one or more characters, voices or images).

That is, the control unit 340 expresses the outgoing call message through the display unit 320 when the form of the outgoing call message extracted by the detection unit 310 is a text or an image, or when the text and the image are combined. Control as possible.

In addition, when the type of the outgoing call message extracted by the detector 310 is voice, the controller 340 controls the voice caller 330 to display the outgoing call message of the voice. At this time, a special ringing signal for informing a call connection request is also output through the voice output unit 330. That is, as the outgoing call message and the ring tone are simultaneously output through the voice output unit 330, the controller 340 controls the ring tone to be reduced by a predetermined level. Alternatively, when the outgoing call message and the ring tone are output through the voice output unit 330, the controller 340 controls the outgoing call message to be displayed after the ring tone is output for a predetermined period. On the contrary, when the outgoing call message and the ring tone are output through the voice output unit 330, the controller 340 controls the ring tone to be output after the outgoing call message is output for a predetermined period.

In addition, when the form of the outgoing call message extracted by the detection unit 310 is a combination of one or more text, video or audio, the control unit 340 allows the text or video to be displayed through the display unit 320 and voice. The voice is controlled to be output through the output unit 330.

The outgoing call messaging method according to the present invention using the system of the present invention described above will be described below.

3 is a diagram illustrating an outgoing call messaging procedure according to the present invention.

The procedure according to the present invention shown in FIG. 3 is preferably performed in a communication network complying with the signaling standard for the calling number display service.

Referring to FIG. 3, the caller inputs an outgoing call message through a program driven in the calling terminal (S1). Subsequently, the caller requests a call connection after inputting a called party's terminal number to request a call connection (S2, S3).

The calling terminal inserts the input outgoing call message and other caller information (CID, caller's name, etc.) into a call request signal for call connection and transmits it to the exchange (S4, S5).

As another example, the caller inputs outgoing call messages in advance for each other terminal number and each terminal number, so that the outgoing call messages for each terminal number are stored in advance in the storage of the calling terminal. In this case, when a caller selects a specific terminal number stored in advance through a driven program and then requests a call connection to the selected terminal number, the outgoing call message previously matched with the request terminal number is automatically stored in the call request signal. Is inserted into the exchange and sent to the exchange. This example may vary depending on how the network operator implements the system.

Next, when the call request signal is received (S6), the insertion process of the call request signal is processed so that the outgoing call message inserted in the call request signal is preferentially displayed (S7). In other words, the CID inserted in the specific area of the CID signal format is replaced with the outgoing call message inserted in the free area so that the calling party terminal number inserted in the call request signal is not displayed on the called terminal. The outgoing call message inserted in the free area is retained and the CID inserted in the specific area is deleted or hidden.

Subsequently, the exchange transmits the processed call request signal to the called terminal (S8).

When a call request signal is received (S9), the receiver terminal outputs a ring tone notifying the call connection request (S10), and simultaneously confirms whether an outgoing call message is inserted into the call request signal (S11).

When the outgoing call message is inserted in the call request signal, the called terminal analyzes the type of the outgoing call message (S12).

Thus, according to the analyzed message type, the outgoing call message is displayed through the display window or the voice output unit (speaker) of the called terminal (S13). Of course, if the calling party terminal number is inserted into the call request signal, the calling party terminal number is displayed together with the calling party message, but the calling party message is first displayed.

If an acknowledgment (ACK) is sent from the called terminal (S14), the exchange receiving the acknowledgment (ACK) completes call setup between the calling terminal and the called terminal (S15). In this way, the call between terminals is realized.

According to the outgoing call messaging method and system therefor according to the present invention as described above, a message having a predetermined length for requesting a call connection request is displayed to the called party before the call is started while the CID is not displayed at the called party. It satisfies the caller's need to terminate the call with the called party without telling his terminal number.

In addition, the present invention is advantageous from the user's point of view because it is possible to simply inform the purpose of the call before the call.

In addition, it is possible to maintain the effect of the CID display service to prevent invasion of communication privacy or immoral behavior.

In addition, the present invention provides a new concept of service that can satisfy the needs of users with strong personalities. In other words, it provides a service to send a simple love message or an appointment message between the callers before the call.

It is a new concept of service that enables network operators to attract a large number of subscribers.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
