Description of the Invention: [Technical Field] The present invention relates to a method for transmitting a short message, and more particularly to a method for transmitting a multimedia message under the Global System for Mobile Communications (GSM) architecture. [Prior Art] The Multimedia Messaging Service (MMS) is a new type of newsletter developed on the basis of the newsletter business. MMS is a global SMS delivery standard developed by the 3rd Generation Mobile Communications Standards Organization (3GPP), according to which users can send different MMS messages. The operation of the user to send the MMS message via the mobile phone is as convenient as the SMS message, and the MMS message created by the user can be automatically and quickly transmitted between the phones. The transmission of the MMS message is still located according to the recipient's mobile number; when the receiver is turned off or temporarily not in the service area, the MMS message will be stored in the Multimedia Message Center (MMSC) until it is properly delivered. The SIM Application Toolkit (STK) is an instruction set, also defined by 3GPP. It is independent of the SIM card and provides additional application functions for the SIM card. However, STK only defines the Short Messaging Service (SMS) transmission instructions, so only SMS messages can be sent under GSM and MMS messages cannot be sent. At present, the integration of SMS SMS and MMS SMS format and transmission discrimination are difficult points that STK has not overcome. SUMMARY OF THE INVENTION 201041420 In view of the above, it is necessary to provide a method for transmitting a multimedia message using the STK under the GSM architecture, and the data can be selectively transmitted by the user through the STK driver layer and the STK interface layer. The MMS newsletter is also in the SMS newsletter to the destination phone. A method for transmitting a multimedia message in a GSM architecture, the gsm architecture includes a SIM card, an STK driver layer, an STK interface layer, and a user interface. The method includes the following steps: (a) after the user inputs an instruction to send a multimedia message on the user interface, the STK interface layer transmits the instruction to the SIM card through the STK driver layer, where the multimedia message includes an SMS message. (b) The SIM card issues an input command requesting the user to input the destination number to the STK driver layer; (c) after receiving the input command, the STK driver layer requests the user input to send the multimedia message through the user interface. The destination number; (d) the STK interface layer determines whether the user inputs the destination number for transmitting the multimedia message; (e) if the user does not input the destination number, the STK driver layer sends the SMS according to the preset number in the SIM card.

(h) If the user needs to send an MMS message, the STK driver layer sends the MMS message sent by the user to the corresponding mobile phone according to the destination number; (i) when the STK driver layer sends the SMS message Or after the MMS newsletter, the STK driver layer will send the result packet into a message packet that responds to the send command and then return it to the SIM 5 201041420 card; and (g) when the SIM card receives the response message packet, an end command is sent to the STK. The driver layer ends the sending of the multimedia message. Compared with the prior art, the present invention provides a method for transmitting an MMS message in a GSM architecture, which can transmit data between the STK driver layer and the STk interface layer when transmitting a multimedia message in the GSM architecture. The user can selectively send an MMS message or an SMS message to the destination phone. [Embodiment] As shown in FIG. 1, it is an architecture diagram of a Global System for Mobile Communications (GSM) that transmits a multimedia message according to the present invention. The GSM system includes a Subscriber Identity Module (SIM), a User Identification Tool (SIM Toolkit hereinafter referred to as STK) 2, and a User Interface 3. The STK2 includes an STK driver layer (STKDriver) 21 and a STK interface layer (STKUI) 22. The SIM card 1 and the STK driver layer 21 are connected to each other, the user interface 3 and the STK interface layer 22 are connected to each other, and the STK driver layer 21 and the STK interface layer 22 are connected to each other, and bidirectional data interaction can be performed therebetween. The multimedia message includes an SMS message and an MMS message, and the SMS message generally refers to a plain text message, and the MMS message generally refers to a multimedia message of text, picture, photo, audio, video, and a combination thereof. The SIM card 1 stores an instruction set corresponding to the SMS message sent by the user. The instruction set is preset by the telecommunications provider. After the user inputs the destination number of the SMS message to be sent via the established instruction set, the SIM card 1 is After receiving the response of the preset instruction, an instruction to send the SMS, such as the SendSMS instruction, is sent according to the corresponding instruction set. In addition, when the STK2 sends out the SMS message, the instruction set in the SIM card 1 sends an instruction to end the transmission of the message according to the transmission result of the SMS or MMS message sent by the STK2 (for example, the transmission succeeds or the transmission fails), for example, the EndSession instruction 'ends The sending task of this short newsletter. The STK2 is an instruction set, which is a GSM standard developed by the 3rd Generation Mobile Communication Standardization Organization (3GPP). It is independent of the SIM card 1 and provides additional application functions of the SIM card 1. Since STK 〇 2 only defines the sending instructions of the SMS message, only the SMS message can be sent under the GSM architecture and the MMS message cannot be sent. In this embodiment, the data conversion between the STK driver layer 21 and the STK interface layer 22 allows the user to selectively send an MMS message or an SMS message to the destination handset. The user interface 3 provides a graphical operation interface for the user to input a multimedia message (including an SMS or MMS message) and a destination number. When the user turns in the destination number, the STK interface layer 22 obtains the destination number. The destination number is transmitted to the SIM card 1 through the STK driver layer 21. In this embodiment, the user must first enter the destination number before sending the MMS message, so the SIM card 1 must have the function of the user input number. Before the user needs to send an MMS message, the SIM card must first issue an instruction that requires user input, such as the Getlnput command. After the STk driver layer 21 receives the command, the STK interface layer 22 requests the user to input the destination number of the MMS message to be sent through the user interface 3, and then the STK interface layer 22 transmits the destination number entered by the user through the STK driver layer 21. 7 201041420 Send to SIM card 1. 2 is a flow chart of a preferred embodiment of a method for transmitting a multimedia message in the GSM architecture of the present invention. In step S20, when the user inputs a selection instruction, such as a Selectltem instruction, to the user interface 3, the STK interface layer 22 transmits the selection instruction to the SIM card 1 through the STK driver layer 21. Step S21' The SIM card 1 issues an input command requesting the user to input the destination number to the STK driver layer 21, such as the Getlnput command. Step 22 $22, after the STK driver layer 21 receives the input command, the STK interface layer 22 will request the user to input the destination number of the multimedia message through the user interface 3. In step S23, the STK interface layer 22 determines whether the user inputs the destination number for transmitting the multimedia message. If the user inputs the destination number, the step S24, the STK interface layer 22 records the destination number in the number record table of the STK driver layer 21 and transmits the destination number to the 0 SIM card 1 by the STK driver layer 21. If the user does not input the destination number, the flow moves to step S34. Step S25 ' After the SIM card 1 receives the destination number, the SIM card 1 generates an instruction to transmit the SMS according to the preset instruction set, for example, the SendSMS command' The received destination number is sent to the STK driver layer 21 after being included in the SendSMS command. In step S26, the STK driver layer 21 decomposes the destination number ' from the SendSMS command after receiving the SendSMS command and compares the destination number with the number recorded in the number record table. 8 201041420 Step S27, the STK driver layer 21 judges whether or not the number record table has the destination number. The corresponding number can be found in the phone number list under normal circumstances, because when the user inputs the destination number on the user interface 3, the STK interface layer 22 records the destination number entered by the user in the number record table of the STK driver layer 21. in. In this embodiment, if the destination number is not present in the number record table, for example, when the destination number recorded in the number record table is incorrect, the STK driver layer 21 prompts the user to input the destination through the user interface 3 in step S28. An error occurs in the number, and the flow returns to step S22 to let the user re-enter the destination number. If the number record table has the destination number, in step S29, the STK driver layer 21 determines through the STK interface layer 22 whether the user wants to send the SMS MMS message or the SMS message. If the user needs to send an MMS message, in step S30, the STK driver layer 21 sends the MMS message to be sent by the user to the corresponding mobile phone according to the destination number. If the user needs to send an SMS message, step S31 'STK driver layer 21 sends the SMS message to be sent by the user to the corresponding mobile phone according to the destination number. Ο Step S32, after the STK driver layer 21 sends out the MMS message or the SMS message, the STK driver layer 21 encapsulates the transmission result (for example, 'send success or transmission failure') into a message packet in response to the SendSMS command and transmits it back to the SIM card 1 . Step S33, after receiving the response message packet, the SIM card 1 issues an end command to the STK driver layer 21, for example, an EndSession command, and the STK driver layer 21 clears the destination number recorded in the number record table after receiving the end instruction to release. The STK drives the storage resources within the layer 21. In the above step S23, if the user does not input the destination number, step 9 201041420 step S34, the SIM card 1 generates a SendSMS command according to the preset instruction set, and sends the preset number in the SIM card 1 to the SendSMS command and then sends the message. The STK driver layer 21 is provided. In step S35, the STK driver layer 21 decomposes the preset number from the SendSMS command after receiving the SendSMS command, and then the process moves to step S31, that is, the STK driver layer 21 sends the SMS message to the corresponding mobile phone according to the preset number. Since the STK driver layer 21 only defines the sending instruction of the SMS message, 'only the SMS message can be sent under the GSM architecture and the MMS 简 message cannot be sent. Therefore, the present invention provides a method for transmitting a multimedia message by using the STK technology in the GSM architecture, which can enable the user to exchange data between the STK driver layer 21 and the STK interface layer 22 when transmitting the multimedia message in the GSM architecture. Selectively send MMS newsletters or SMS newsletters to destination phone orders. The above is only the preferred embodiment of the present invention, and has been used in a wide range of applications, and all other equivalent changes or modifications that are not included in the spirit of the present invention should be included in the following patent application. Within the scope.
