Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a system configuration diagram of a mobile communication network according to a preferred embodiment of the present invention, which includes a mobile communication terminal (100, 102), a base station (110, 112), a switching center (Mobile Switching Center: 120), a VLR (Visitor Location Register): Visitor location register) 122, SMS server 130, and HLR (Home Location Register) 140.

Prior to the description of the configuration diagram, in the present embodiment, the first and second mobile communication terminals 100 and 102 and the first and second base stations 110 and 112 are respectively classified in order to distinguish between the transmitting and receiving sides. It will be apparent to those skilled in the art that the above description is for convenience of description and is not limited to the number of terminals and base stations.

In addition, in the present embodiment, the first mobile communication terminal 100 is located in the area of the first base station 110, and the called mobile communication terminal requesting the call from the first mobile communication terminal 100, that is, the second mobile communication terminal. Assume 102 is located within the area of the second base station 112, respectively.

As shown, the information of the first or second mobile communication terminal 100, 102 is transmitted to the switching center 120 via the first or second base station 110, 112, respectively, to the switching center 120 The transmitted information is transmitted to the second and first mobile communication terminals 102 and 100 via the second and first base stations 112 and 110, respectively. That is, text messages transmitted and received by the first and second mobile communication terminals 100 and 102 are connected to the switching center 120 through the first and second base stations 110 and 112 for high frequency signal processing and call processing. .

Switching station 120 has a VLR 122, and interworks with SMS server 130 and HLR 140 to handle calls of mobile subscribers.

The SMS server 130 is connected to the switching center 120 and the HLR 140 to process the SMS, to set the SMS parameters, interpret the communication service identifier and the destination address of the input signal, and transmit it to the corresponding network element. Do this.

The VLR 122 is a DB that temporarily stores subscriber information related to the mobile communication terminals 100 and 102 while the mobile communication terminals 100 and 102 are in an area controlled by the VLR 122. The information of the mobile communication terminal and subscriber registered as a location is retrieved from the HLR 140 and temporarily stored.

Hereinafter, the above-described configuration will be described in detail with reference to a flowchart of FIG. 2 attached to a process of transmitting a text message during a call in a mobile communication network according to an exemplary embodiment of the present invention.

First, in step S200, a call is connected between a transmitting terminal, for example, a first mobile communication terminal 100 and a receiving terminal, for example, a second mobile communication terminal 102. The call connection state refers to a state in which a call path is formed between mobile communication subscribers through the base station 110, 112, the exchange station 120, the VLR 122, the HLR 140, and the like. The voice connection between the 100 and the second mobile communication terminal 102 is possible.

At this time, in step S202 it is determined whether the text transmission function key on the first mobile communication terminal 100 is input. That is, step S202 is a step of determining whether a key signal for text message input is applied in the first mobile communication terminal 100.

As a result of the determination in step S202, when the text transmission function key formed on the terminal 100 is input, the first mobile communication terminal 100 proceeds to step S204 to change the setting to the text transmission mode.

The text transmission mode is a mode in which the user can input any text, for example, a phone number, ID, account number, etc. through the terminal 100, a mode for enabling text input while a call path is formed. to be.

In addition, when inputting a non-generic phone number, the user may search for and enter a phone number contained in his / her phonebook. The receiver may check the received phone number and then press the call button to make a call again.

At this time, in order to implement a text message transmission technology during a call according to this process, it is possible to input text using only the terminal, but then, by connecting an ear microphone or hands-free to the terminal, It would be desirable for the user to be in a state where the user can view the screen on the terminal.

That is, when performing a text input during a call using only the terminal, it is more preferable that such additional apparatus is separately provided because it is not possible to input text during a call.

On the other hand, in step S206, it is determined whether the predetermined character input is completed. That is, it is determined whether a text message is completed and a predetermined key for requesting transmission is input.

As a result of the determination in step S206, when the text input is completed, the text message is transmitted from the first mobile communication terminal 100 to the first base station 110 and the switching center 120, and the switching center 120 sends the SMS server 130. SMS message is processed by the SMS server 130, and the SMS server 130 interprets the service identifier and the destination address through the VLR 122 and the HLR 140, and transmits the SMS information to the corresponding network element.

Therefore, the SMS containing the predetermined text message is transmitted to the second mobile communication terminal 102 through the switching center 120, the second base station 112, and the like (S208).

According to the present invention, even when a mobile subscriber is moving or a memo is difficult, accurate information can be delivered to the other party. On the receiving side, the receiving side can immediately check the received message and press the call button if the phone number is used to make a call again. In addition, since text messages are transmitted during call occupancy, communication time and data transmission volume are increased, thereby increasing profits for mobile communication services.

As mentioned above, although this invention was concretely demonstrated based on the Example, this invention is not limited to this Example, Of course, various changes are possible within the range which does not deviate from the summary.
