The present invention relates to a character transmission method of a mobile communication terminal, and more particularly, to a character transmission of a mobile communication terminal using SMS, which enables the transmission of a character as well as a character of the mobile communication terminal using a conventional SMS transmission method. It is about a method.

In general, personal communication service is an inexpensive and universal mobile service that enables an individual to perform voice and low-speed data communication regardless of place and time using a mobile communication terminal. The current wired / wireless communication network is mainly focused on voice communication. In recent years, due to the steady increase in the number of subscribers of data services, its use is expanding to non-voice services such as data services.

SMS (Short Message Service) supplementary service is a service that performs additional functions other than basic message delivery through a special type of message by providing additional information to the subscriber by loading additional information on the SMS basic service.

However, the existing SMS is limited to providing only text-oriented characters to the incoming customers, and if the character is to be transmitted to another person, the character call is to be paid according to the size of the character each time. There was a problem that the service could not be activated like a short message service.

Accordingly, the present invention is to solve the above-mentioned conventional problems, an object of the present invention is to download the character image and the code by selecting a character after the mobile communication terminal is connected to the character server through a wireless Internet network The present invention provides a method of transmitting a character of a mobile communication terminal using SMS, which can transmit various characters at low rates by transmitting a text message and a character through SMS to a destination terminal in which a code corresponding to the character is stored.

Character transmission method of the mobile communication terminal using the SMS to achieve the object of the present invention as described above, the step of downloading the selected character to the calling terminal connected to the character server is stored a plurality of character images through the wireless Internet network, Transmitting a character downloaded to the terminal and a written text message to the called terminal using SMS, requesting information of the called terminal transmitted from the calling terminal to the HLR and determining whether the character can be transmitted to the called terminal; When it is possible to transmit the character to the destination terminal, transmitting the character and the text message to the destination terminal, and if the character transmission to the destination terminal is not possible, the step of notifying the transmission failure to the calling terminal.

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

1 is a diagram showing the configuration of a system transmission network according to the present invention.

As shown in FIG. 1, the caller terminal 10 and the caller terminal 10 that download and store various character images by accessing the character server 30 having the character image stored thereon through the wireless Internet network 23 and generated therein Base stations 11 and 18 that receive a call signal and form a call path with the destination terminal 20 corresponding to the received call signal, perform call signal processing received through each base station and control a base station for call path formation. Switch (12, 16), the Home Location Register (HLR) 13 for providing a location of the called terminal 20 and notifying whether the called terminal 20 can receive character and text messages, Short Message Service Center (SMSC) 14 which enables the transmission of text and text messages.

In this case, the caller 10 and the called terminal 20 may include a code corresponding to a predefined character (hereinafter referred to as a “character image code”) or download a character image from the character server 30. When receiving, the code defined in the character is also downloaded.

In addition, the calling terminal 10 connected to the character server 30 is a character selected by the character server 30, if the destination terminal 20 to transmit the character is a terminal that does not contain the code of the character When the user of the calling terminal 10 transmits a character by using the SMS by selecting the present function of the image and the code and transmitting it to the called terminal 20, the called terminal including only the character code in the text area of the existing SMS ( 20). At this time, the called terminal 20 should store the character and code transmitted from the character server 30 to the present function.

2 is a flowchart illustrating a character transmission process of a mobile communication terminal using an SMS according to the present invention. Referring to FIG. 2, a character transmission method of a mobile communication terminal using an SMS according to the present invention will be described below.

First, the user accesses the character server 30 that provides a plurality of character images through the wireless Internet network 23 using the calling terminal 10 (S100) and selects a required character image, and then the calling terminal Download to (10) (S110).

Here, the method of downloading the character by the caller terminal 10 to access the character server 30 is selected by selecting any one of SMS, WAP, ME, JAVA, the character server 30 of the character In addition to downloading, it provides additional functions such as presenting and snagging a character.

The character downloaded to the calling terminal 10 is transmitted to the called terminal 20 using SMS along with a text message by the user, the character stored in the calling terminal 10 with the code number defined in the character Since the character image is stored, the character image code to be transmitted to the destination terminal 20 is transmitted from the character code defined in the text area for transmitting the text message and transmitted together with the text message (S120).

The SMS system transmits the information of the called terminal to the HLR 13 using the telephone number of the called terminal 20 inputted to transmit the character image code and the text message transmitted from the calling terminal 10 to the called terminal 20. ) Will be requested (S130). The HLR 13 determines whether the destination terminal 20 includes a corresponding character code that can be received by the character image code transmitted from the calling terminal 10, and transmits the determination result to the SMSC 14. It becomes (S140).

In this case, when the corresponding code of the character to be transmitted to the called terminal 20 is embedded, the SMSC 14 transmits the character image code and the text message through the exchange 16 of the called terminal 20. (S150).

On the other hand, if the corresponding code of the character to be transmitted to the terminating terminal 20 is not embedded in the terminating terminal 20, the SMSC 14 transmits the character to the terminating terminal 20 to the terminating terminal 20 Notify that this has failed (S160).

In addition, when the transmission of the character fails because the corresponding code of the character to be transmitted to the called terminal 20 is not embedded in the called terminal 20, the calling terminal 10 transmits to the character server 30. A character image and a code to be transmitted may be transmitted to the called terminal 20 by using the present function, which is an additional function of the character server 30. The terminating terminal 20 stores the character and the code transmitted from the character server 30, so that when the calling terminal 10 transmits the character and the text message using SMS, the receiving terminal 20 displays the character on the display unit. Done.

In this way, the character can be transmitted at a low call rate of the existing SMS method, since the corresponding character code that can be substituted for the character is stored in the terminal. It is possible. This service is not limited to characters, but can be applied to various contents such as ringtones and images.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments without departing from the spirit of the present invention as claimed in the claims. Of course, any person skilled in the art can make various modifications, and such changes are within the scope of the claims.
