The present invention relates to an SMS of a mobile communication terminal, and more particularly, to convert and transmit Unicode to GSM7 code during transmission of SMS including Unicode data. The present invention relates to a mobile communication terminal having an SMS message service function including Unicode for converting the information back to the inverse and providing the same, and a service method thereof.

Currently, a mobile communication terminal provides a Short Message Service (SMS) as a method for transmitting and receiving necessary information without call connection between callers.

The SMS uses two transmission methods when SMS is transmitted when Unicode data is included in the transmitted message.

One of the methods is that when the SMS message contains Unicode data, the transmitting mobile communication terminal packs the data in the input data format, and the receiving mobile terminal outputs the received data to the display unit as it is. to be.

In another method, when the SMS message includes the Unicode data, the transmitting mobile communication terminal replaces the Unicode data with the GSM7 code data of a similar form and packs it, and transmits the received data. In the mobile communication terminal, the received data is output to the display unit in the form of the received data. In this method, the Unicode data input from the transmitting mobile communication terminal is converted into GSM7 code data and output from the receiving terminal.

An SMS message created from the SMS message including the Unicode data as described above is transmitted from the transmitting mobile terminal to the receiving mobile terminal via the SMSC and transmitted in the network for the SMS message to be viewed by the receiving mobile terminal. The procedure is all the same. That is, in the network, when the sending mobile communication terminal packs and transmits an SMS message, it is received by the receiving mobile communication terminal via the SMSC, and the receiving mobile communication terminal parses the received SMS message and outputs it to the display unit. .

In the SMS message transmission procedure as described above, the packing or parsing of the SMS message transmitted in the mobile communication terminal should be performed without distortion of data. That is, the GSM7 code data (data) is a GSM7 code data (data), the Unicode data (Unicode data) is packed (packed) and parsed (Unicode data).

The operation of two methods of transmitting an SMS when the Unicode data is included as described above will be described in more detail with reference to the accompanying drawings.

1 is a flowchart illustrating a general SMS transmission procedure of the prior art, and FIG. 2 is a flowchart illustrating an SMS transmission procedure having data consisting of GSM7 codes of the prior art.

In the above-described prior art illustrated in FIGS. 1 and 2, two methods of transmitting SMS when Unicode data is included, all procedures follow the above-described general SMS transmission procedure, and SMS data packing. Since only the (packing) part is different, only the difference between the parts for packing data will be described below.

First, a general SMS transmission procedure of the prior art will be described with reference to FIG. 1.

As shown in FIG. 1, when the user writes SMS data based on the contents input for the SMS message (S1), the created SMS data is in the original format without changing the data format, that is, Unicode is Unicode. The GSM7 code performs packing with the GSM7 code (S2).

The SMS message packed by the process S2 is transmitted by the mobile communication terminal (S3), and the transmitted SMS message is received by the receiving mobile communication terminal via the SMSC (S4) (S5).

The receiving mobile communication terminal parses the received SMS message according to the packing type, that is, Unicode in the case of Unicode, and GSM7 in the case of GSM7 and outputs it to the display unit (S6 and S7).

2 is a flow chart showing an SMS transmission procedure with data consisting of prior art GSM7 codes and Unicode.

As shown in FIG. 2, when the SMS message to be transmitted is set to be packed with GSM7 code data, when the user writes the SMS data based on the input contents for the SMS message (S11), the SMS data is transmitted to the created SMS data. It is determined whether the code is included (S12).

If the result of the determination in step S12 does not include Unicode, the GSM7 code is maintained. If the result of the determination in step S12 includes the Unicode, one byte of 00 data is added to the GSM7 code. Convert to data (S13).

SMS messages composed only of Unicode or GSM7 code data by S11 to S13 are sent after being packed by the SMS packing procedure, and data with Unicode data are also sent after being packed by the SMS packing procedure and received via SMSC. It is received at the mobile communication terminal (S14, S15, S16, S17).

The mobile communication terminal receiving the SMS message in step S17 parses the SMS message composed of Unicode data using Unicode, and parses the SMS message composed of GSM7 code data into GSM7 code data and outputs it to the display unit. (S18, S19).

Looking at the SMS packing method in the SMS message transmission method in the prior art as described above, if the GSM7 code data is GSM7 code data, Unicode data is included, convert all the GSM7 data to Unicode data and then Unicode Packing is done with data. In this case, an SMS message composed of only GSM7 code data can be inputted up to 160 characters in one PDU (Packet Data Unit), and in case of a message including at least one Unicode data, the entire message can be input in 70 characters in one PDU. This is possible.

Therefore, in the case of the conventional SMS transmission method, when packing an SMS message in the form of GSM7 code data, up to 160 characters can be input in one PDU (Packet Data Unit), but the Unicode is one. Even if it is included, since the packing is performed in Unicode, up to 70 characters are packed in one PDU, and thus, there is a problem in that loss of user or network resources occurs economically in data transmission.

In the above-described conventional SMS transmission method, a character that can be input into one PDU is changed since the packing method of the SMS is changed to Unicode when at least one Unicode data is entered during SMS writing. Since the number of is reduced from 160 characters to 70 characters, the user may be regarded as forcing the user twice the fee, which may cause user complaints.

For this reason, the GSMA TWG Technical Note 44 has proposed a method of converting Unicode data into a similar form of GSM7 code data for transmission. However, in the case of replacing Unicode data with GSM7 code data according to GSMA TWG Technical Note 44, the requirements are limited only if the user can understand the meaning after the replacement.

Therefore, according to the recommendation of GSMA TWG Technical Note 44, when all data is transmitted as GSM7 code data only, it is transmitted by converting the Unicode data into a similar form of GSM7 code data. The number of characters packed into a single PDU is 160 characters, so the user's claim for the fee can be resolved, but the Unicode data is similar to GSM7. Since the message is transmitted after changing to code data, the message received at the receiver side is output as a message in which all Unicode data is converted to GSM7 data, so that the content may be output in an ambiguous form. Accordingly, the recommendation also places a limitation on converting Unicode to GSM7 code as long as there is no distortion of meaning.

Accordingly, the present invention is to solve the above-mentioned problems in the prior art, and after generating a code DB corresponding to the GSM7 code and Unicode, if the SMS message data includes Unicode, the GSM scheme by converting to the GSM code SMS message service function that includes Unicode to transmit the data by packing it, and converts the Unicode data converted into GSM7 code to Unicode by using the code DB during parsing. An object of the present invention is to provide a mobile communication terminal and a service method thereof.

In order to achieve the above object, a mobile communication terminal having an SMS message service function including Unicode according to the present invention is a mobile communication terminal having an SMS message service function. A mapped code database; If Unicode is included in the SMS data to be transmitted when the SMS message is transmitted using the code database, the Unicode is converted into a GSM7 code and outputted. When parsing a received SMS message, the Unicode is converted into the GSM7 code. A code conversion unit for converting and outputting back to Unicode; Detect whether Unicode is included in the sent SMS message of the SMS message and output the encoded message to the code conversion unit, and indicate whether or not the Unicode data is included, pack the data, transmit it, and parse the received SMS message. When the Unicode corresponding GSM7 code is detected by checking whether the Unicode data is included, the code is outputted to the code conversion unit and then received the coded data, and the received SMS message is output to the display unit as the GSM7 code and the Unicode. SMS processing unit; characterized in that comprises a.

Whether or not the Unicode data is included is indicated by a converting flag displayed in the reserved area of the SMS message.

The SMS processor may output the SMS message to the display unit as Unicode data as Unicode and GSM7 data as GSM7 code.

An SM message service method including Unicode of a mobile communication terminal of the present invention for achieving the above object includes a Unicode search process for determining whether Unicode is included in a transmission target SMS data; A code conversion step of converting the Unicode into a GSM7 code when Unicode is found in the Unicode search; An SMS transmission process of SMS packing and transmitting SMS message data converted by the Unicode retrieval process and the code conversion process; An SMS receiving step of parsing after receiving the SMS message data transmitted by the SMS sending step; A Unicode conversion process of retrieving the Unicode converted GSM7 code from the SMS message data received in the SMS reception process and converting the Unicode message into Unicode And a message output process of outputting the SMS message to a display unit.

The Unicode retrieval process may include an initial setting process for converting a flag to set an initial value to a value indicating that Unicode is not included in a converting flag that indicates whether Unicode is included in the SMS message.

The Unicode conversion process includes a converting flag conversion process of converting the SMS message to the value indicating that Unicode is included in the converting flag indicating whether or not to include Unicode; characterized in that it comprises a.

The message output process may be a process of outputting Unicode data among the parsed SMS data as Unicode and GSM7 code data as GSM7 code.

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

3 is a block diagram of a mobile communication terminal according to an embodiment of the present invention.

As shown in FIG. 3, a mobile communication terminal according to an embodiment of the present invention, like a conventional mobile communication terminal, includes an SMS processing unit 111 that controls an SMS service function, and transmits and outputs an SMS message. A control unit 110 controlling the voice and data communication of the mobile communication terminal; A key input unit 120 for receiving a user control command; A display unit 130 for outputting and displaying a driving state of the mobile communication terminal; A storage unit (not shown) for storing driving software and user input information of the mobile communication terminal and unique information of the mobile communication terminal; It includes an RF unit 160 for performing RF communication with the mobile communication network and the audio processor, MP3 playback unit, not shown in the figure,

A code database 140 in which Unicode and GSM7 codes for SMS messages are mapped; If the SMS data to be transmitted when transmitting the SMS message of the mobile terminal includes Unicode, convert the corresponding Unicode into GSM7 code using the code database and pack the converted Unicode message. When parsing the received SMS message, the SMS is transmitted. When the message includes the GSM7 code, the code database further comprises a code conversion unit 150 for converting the Unicode-compatible GSM7 code data into Unicode.

The code database 140 having the above-described configuration stores one-to-one mapping between Unicode and GSM7 codes. That is, for normal converting operation, like Unicode T9 DB, Unicode words are mapped to GSM7 words of similar type and stored. The code database 140 storing the above-described information may be stored in a storage unit of the mobile communication terminal or in a nonvolatile memory such as a flash memory separately from the storage unit.

The SMS processing unit 111 performs SMS packing processing on the transmitted SMS data and SMS parsing of the received SMS message, and then outputs the parsed SMS message to the display unit 130 under the control of the control unit 110. . When the SMS message is received, a converting flag is detected in the header to determine whether the Unicode data converted to the GSM7 code is included, and the determination value is output to the code conversion unit 150.

The code conversion unit 150 monitors whether Unicode data is input when SMS message data for transmission is input. When Unicode data is input, converting the Unicode data inputted using the code database 140 into GSM7 code data, and converting plug value for indicating in the SMS header that there is Unicode converted to GSM7 code It generates and outputs to the SMS processing unit 111. The SMS processing unit 111 writes the converting information by using one of the remaining portions of the SMS header portion as a converting flag between Unicode or GSM7 codes. This is for the receiving mobile communication terminal to refer to this flag to code convert the Unicode-converted GSM7 code back to Unicode.

In addition, when the SMS message is received, the SMS processor 111 outputs a signal confirming that the SMS message received from the converting flag has Unicode data converted into a GSM7 code, and the SMS message data received by the SMS processor 111 is received. After detecting the GSM7 code whose Unicode is converted by the code conversion unit 150 from the message data parsed and outputted, it is converted into Unicode data using the code database 140 and outputted to the SMS processing unit 111. And the SMS processing unit 111 outputs the received Unicode data to the display unit 130.

The processing of the SMS message service method including the Unicode of the mobile communication terminal of the present invention described above is a packing / parsing due to a converting flag added to the SMS header part in a general SMS transmission procedure. In the procedure, a process of transcoding Unicode to GSM7 code when packing and converting Unicode converted to GSM7 code back to Unicode when parsing is added.

4 is a flowchart illustrating an SMS transmission procedure including Unicode according to an embodiment of the present invention.

As shown in Fig. 4, when the user writes the SMS data by inputting the SMS message (S21), the SMS processing unit 111 sets the converting flag to FALSE (this is not user's first FALSE as the user's setting). Can be set to TRUE). Setting the converting flag to FALSE as described above sets the converting flag to FALSE when the SMS message data is only packed with GSM7 characters, thereby allowing the receiving mobile communication terminal to separately set the converting flag. This is to prevent the conversion procedure of (S22).

Next, the SMS processing unit 111 determines whether Unicode is included in the SMS message data to be packed (S23).

If the result of the determination in step S23 includes the Unicode, the SMS processing unit 111 outputs the corresponding data to the code conversion unit 150 and sets the converting flag to TRUE to receive the mobile terminal. Allows the SMS message to know that it contains the Unicode translated GSM7 code. Next, the code conversion unit 150 converts the Unicode into GSM7 code by referring to the code database 140. At this time, unlike in the prior art, the conversion of data does not occur by converting the Unicode corresponding to the word meaning Unicode to the GSM7 code word corresponding to the word (S24).

Thereafter, it is determined whether the input of the SMS message is terminated (S25).

If the input of the SMS message is not terminated as a result of the determination of step S25, the process returns to step S21 and repeats the processes of S21 to S25 until the input of the SMS message is completed.

Next, when the input of the SMS message is completed as a result of the determination in step S25, the packing is performed through the mobile communication network after packing the input completed SMS message (S26).

In the description of FIG. 4, in the SMS message transmission process according to an embodiment of the present invention, the converting process of converting the Unicode into the GSM7 code is performed simultaneously with the input of the SMS message. The converting process of converting into GSM7 code may be performed in parsing process after input of SMS message is completed.

The converting flag is initially set, and when the Unicode is generated, it is changed so that the initial converting flag is not changed in the case of the SMS message which does not include the Unicode, and the initial converting flag is included in the Unicode. To change whether or not Unicode is included.

That is, the default setting of the converting flag is FALSE, and the setting of the converting flag may be set to TRUE from the first occurrence of the Unicode character during the writing of the SMS.

In this case, when the created SMS is only a GSM7 character, the converting flag becomes FALSE when packing, so that the process of converting Unicode to GSM7 is not performed. On the other hand, if the composed SMS message contains a Unicode character, the converting flag is set to TRUE during packing, and the Unicode data is referred to the transcoding database 140. After converting (converting) to GSM7 code data, the SMS is packed and transmitted.

5 is a flowchart illustrating an SMS receiving procedure including Unicode according to an embodiment of the present invention.

The SMS message transmitted by the process of FIG. 4 is received by the receiving mobile communication terminal (S31).

In step S31, the SMS processing unit 111 of the receiving mobile communication terminal receiving the SMS message performs parsing on the received SMS message (S32).

At this time, the SMS processing unit 111 checks the setting of the converting flag of the header portion during the parsing of the SMS message in step S32, and whether the received SMS message includes Unicode converted to GSM7 code. Judge. That is, as shown in FIG. 4, when the SMS message is composed of only GSM7 codes when transmitting, when the converting flag is FALSE, when FALSE is detected, it is determined that Unicode is not included, and when TRUE is detected, Unicode is included. It is determined that the (S33).

If the SMS processor 111 determines that the received SMS message includes the Unicode converted to the GSM7 code, the code conversion unit 150 is driven to read the Unicode-compatible GSM7 code data. In operation S34, the code database 140 converts the code into a GSM7 code.

 S33 and S34 processing is repeated until the conversion of the received SMS message to the Unicode data converted to GMS7 code is completed. If all SMS messages are parsed by this processing, the parsed SMS message is converted to GSM7. The code is a GSM7 code, which terminates the SMS message receiving process of outputting Unicode data to the display unit 130 in Unicode (S35 and S36).

When the SMS message service includes the Unicode data in the SMS message service, the present invention converts the data into a GSM7 code to perform SMS packing so that up to 160 characters can be written in one PDU, thereby reducing the SMS message fee. It provides a reduction effect.

In addition, the present invention described above, even in the receiving mobile communication terminal, the data of the received SMS message, Unicode data is Unicode data, GSM7 code data by outputting the GSM7 code as GSM7 code and Unicode as in the prior art This provides an effect of solving the problem that the mixed SMS message is outputted indefinitely.
