Abstract

PURPOSE: A method for producing and transmitting a character message during conversation of a communication terminal is provided to transceive a short message produced during conversation with the other terminal, by using a wired and wireless terminal having a function to transmit a short message through a PSTN(Public Switched Telephone Network), so that the other party confirms conversation contents visually. CONSTITUTION: A terminal occupies a speech path and starts conversation(S110). Whether production of a short message during conversation is requested is checked(S120). If not, the conversation is maintained(S130), and if requested, the terminal moves to a message producing menu to produce a short message(S140). A recipient number and a short message server number necessary for a protocol are produced together with the short message(S150). If the short message is completely produced, a user presses a flash button to transmit the recipient number and the short message server number to a short message server(S160). The short message server paged by the terminal notifies that receiving the short message from the terminal is prepared(S170). The terminal transmits the short message to the short message server and the short message server transmits the short message to a recipient(S180). And the recipient processes the received short message and restores the speech path again to maintain the conversation(S190).

Description

How to create and send a text message during a call in a communication terminal {Method for short message service at off-hook on a phone}

The present invention relates to the creation and transmission of a text message of a communication terminal, and more particularly, to create a short message during a call using a wired or wireless terminal implemented with a short message service (or SMS) function through a PSTN network. The present invention relates to a method for creating and transmitting a text message during a call of a communication terminal for transmitting the same to a counterpart.

In general, a short message service is a method of transmitting a text message of a certain length through a communication network, and is provided as an additional service by a communication service provider mainly performing a voice call related service. In particular, the mobile communication network subscribers have high utilization of short message service.

However, in the conventional mobile communication terminal, a short message is created and transmitted and received when not in a call. Therefore, the mobile communication terminal has a disadvantage in that it cannot perform a function of creating and transmitting a short message during a call.

On the other hand, there is no service for transmitting and receiving a short message from the wired or wireless terminal using the PSTN network, the terminal for realization is not implemented. Therefore, in the conventional PSTN network, short message creation and transmission / reception functions during a call were not available.

The present invention was created in order to solve the above-mentioned conventional problems, and an object of the present invention is to create a short message during a call using a wired / wireless terminal having a short message transmission function through a PSTN network, and then make a current call. The present invention provides a method for creating and transmitting a text message during a call of a communication terminal for transmitting and receiving to a user so that the other party can visually check the contents of the conversation.

In order to achieve the above object, a method of creating and transmitting a text message during a communication of a communication terminal of the present invention includes: determining whether a short message is required while the terminal occupies a communication path and is busy; When the short message is required, the terminal providing an input window for creating the short message so that the user designates a recipient to create the short message; Invoking the short message server according to a set protocol when the short message is created; Sending, by the terminal, the created short message to the called short message server; And sending, by the short message server receiving the short message, the short message to the designated recipient.

1 is a flow chart of a method for creating and transmitting a text message during a call in a communication terminal according to an embodiment of the present invention.

2 is a block diagram of a communication protocol between a communication terminal and a message server according to an embodiment of the present invention.

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

1 is a flowchart illustrating a method for creating and transmitting a text message during a call in a communication terminal according to an embodiment of the present invention, and FIG. 2 is a block diagram of a communication protocol between a communication terminal and a message server according to an embodiment of the present invention.

The present embodiment is applied to a configuration including a terminal capable of composing a short message during a call and a protocol capable of transmitting and receiving a message between the terminal and a message server during a call.

According to FIG. 1, in order to create and transmit a text message during a call, the terminal first enters a state in which the terminal occupies a call path and starts a call. Occupy by call is made by the operation off-hook for the call with the other party in the terminal (S110),

In the busy state, a determination is made whether a busy short message (SMS) is required. When a specific button on the terminal is pressed or a specific menu item is selected, it may be determined that a short message writing request is issued during a call (S120).

So if the text message is not required to create a call maintains the call state (S130).

On the other hand, the initial input menu must be configured to transmit the content of the short message. The input menu includes an input window for inputting a server number for sending and receiving a message to and from a short message server.

If a short message is required during a call, the terminal moves to a message creation menu for creating a short message. In the state of moving to the message composition menu, a user writes a short message using a terminal according to a general short message writing technique. The specific technique of writing the short message may be performed in a different manner for each terminal model (S140).

Then, a recipient number and a reply number necessary for a protocol for exchanging the message with the short message server of the network operator side are prepared together with the short message server number and the short message (S150).

When the creation of the short message is completed, the user presses the flash button of the terminal to transmit the short message server number, the recipient number, and the reply number created above to the short message server (S160).

That is, after the terminal prepares the necessary part including the content of the short message and presses the flash button, as shown in FIG. 2, the signal 1 set in the terminal is transmitted to the short message server according to the protocol between the terminal and the short message server. . The signal 1 set here is a signal for calling a short message server performing a short message service in a terminal, and is responsible for calling a short message server designated by a short message server number and specifying a recipient number.

The short message server called by the terminal notifies the terminal that it is ready to receive the short message (S170).

In this case, the corresponding short message server prepares the short message service according to the protocol by referring to the information transmitted from the terminal in FIG. 2, and then transmits the set signal 2 to the terminal. The set signal 2 is for indicating that the short message server is ready to provide a short message service to the terminal calling the terminal and can receive the short message sent from the terminal.

When the short message server is notified of the preparation for receiving the short message, the terminal transmits the set signal 3 to the short message server. The set signal 3 transmitted by the terminal is a short message created by the user, which may include a reply number (S180).

When the short message server receives the recipient number and the short message from the terminal, the call is already connected to notify the recipient of the short message and the short message is transmitted.

The receiver is then notified of the receipt of the short message from the short message server to temporarily mute the call and receive the short message. When a short message is received, the message is heard as noise in the user's ear on the voice call path, so such a temporary silence is required.

In addition, the short message server notifies the terminal when the short message is received from the terminal. That is, the short message server notifies the completion of reception of the short message by transmitting the set signal 4 to the terminal.

The receiver processes the received short message, displays it on a display means such as an LCD (Liquid Crystal Display), and then recovers the call back to continue the call with the sender (S190).

At this time, the terminal of the sender side that has sent the short message is in a state of receiving the completion of the short message reception from the short message server, and thus the call path is restored and the call with the receiver is possible.

As such, in the present embodiment, it is possible to create and transmit a text message during a call between subscribers in a call by occupying the call path, and to generate noise due to text message transmission by temporarily muting the call path of the receiver side when transmitting the corresponding text message. It can be prevented.

The embodiments described above are within the scope of various changes, modifications, and equivalents of the present invention. Therefore, the present invention is not limited to the description of the examples.

According to the method for creating and transmitting a text message during a call of the communication terminal of the present invention has the following effects.

Compared to the conventional wired / wireless telephones, the short message service cannot be provided. However, the present invention enables the creation and transmission of short messages during a call using a wired / wireless telephone installed at home in a PSTN network.

In particular, users who are not actively using information can easily use the short message service, and by using the short message creation and sending / receiving function during a call, the hearing impaired person visually talks with the other party using a text message instead of the voice call. There is an advantage that the convenience of the service can be increased.
