Description

How to Resend Broadcast Short Message from Mobile Device {METHOD FOR RETRANSMITTING BROADCAST SHORT MESSAGE IN MOBILE COMMUNICATION TERMINAL}

The present invention relates to a method for transmitting a short message in a mobile communication terminal, and more particularly, to a method for retransmitting a short message to a telephone number that fails to be transmitted.

Mobile communication terminals are rapidly spreading due to the convenience of portability, and thus service providers (terminal manufacturers) are competitively developing terminals having more special functions to secure a large number of users. Terminal manufacturers) are competitively developing terminals with more special functions to attract many users. For example, a mobile communication terminal can be used for various purposes such as phone book, game, scheduler, short message, internet, e-mail, morning call, etc. It provides a function. In particular, one of the most used functions in the mobile communication terminal is the short message transmission.

Meanwhile, among the short message transmission methods, there is a method of simultaneously transmitting the same short message to a plurality of counterparts, which is called "broadcasting transmission".

In the prior art, when performing a broadcast transmission, if a phone number of one of the broadcast transmission telephone numbers fails to transmit, the mobile communication terminal displays a message indicating a transmission failure and immediately stops the broadcast transmission.

1 is a view showing screens displayed when performing broadcast transmission in the prior art. Referring to FIG. 1, the broadcast transmission process is as follows.

First, (a) shows the "message management" window displayed when the user enters the text transmission key. The message management window includes a plurality of selection items. When the user selects item 2 on the screen (a), the terminal displays the "outgoing message" window as shown in the screen (b). Again, if item 1 is selected on the screen (b), the terminal displays the "Write Letter" window as shown in the screen (c). Here, when the user selects item 1 (write a new sentence), the terminal displays a sentence editing window (not shown), and the user inputs a sentence by operating a keypad. After inputting the sentence and inputting the confirmation key, as shown in (d), a message asking whether to keep the sentence is displayed. At this time, if the user selects a sentence storage (Yes), the input sentence is stored in the corresponding area of the memory.

After the sentence is stored, the terminal displays a window for entering a relative number as shown in (e) screen. At this time, the user inputs a plurality of telephone numbers for broadcasting. After inputting the plurality of telephone numbers and inputting a confirmation key, the terminal displays a window for inputting a number to be contacted as shown in (f) screen. At this time, the user inputs a telephone number to be contacted by operating the keypad. If the confirmation key is input after the telephone number to be contacted is input, (g) a display showing the progress of the transmission is displayed as shown on the screen, and the short message is sequentially transmitted to the plurality of telephone numbers. In this case, when the terminal transmits a short message to a specific telephone number and receives an ACK from the system (if the transmission is successful), the terminal transmits the short message to the next telephone number.

When the short message is transmitted to the plurality of phone numbers, the terminal displays a message asking whether to save the outbox as shown in (h) screen. At this time. If the user selects Save Outbox (Yes), the terminal saves the information of the last short message (short message (sentence) + last sender number + number to be contacted) in the corresponding area of memory and displays the standby screen. If not, select "No" to display the standby screen immediately. On the other hand, if a transmission failure occurs during the broadcast transmission, the terminal displays a message asking whether to store the pending message together with a failure message as shown in (i) screen. If the user selects Hold (Yes), the terminal saves the information (short message (sentence) + failed party number + contact number) of the short message in which transmission failed. Display, otherwise select "No" to display the standby screen immediately.

As described above, if a transmission failure occurs during broadcast transmission, a failure message is displayed with the transmission interruption. At this time, the user can not know the transmission complete phone number (receive side phone number) and the transmission failed phone number. Therefore, the user must perform the work for broadcast transmission again from the beginning. For example, even when the short message is stored in the pending box and the stored contents are recalled and transmitted again, it is inconvenient to re-enter a plurality of telephone numbers for broadcast transmission. In this case, the user is at risk of financial failure and unsuccessful transmission by sending a short message back to the list of existing broadcast transmission telephone numbers. In particular, short messages with transmission failures are more likely to fail in subsequent transmissions. As such, when the broadcast transmission fails, the mental and physical damage to the user is great.

Accordingly, an object of the present invention is to provide a method for displaying a list of failed telephone numbers generated during broadcast transmission in a mobile communication terminal on a display window.

Another object of the present invention is to provide a method for retransmitting a short message to a transmission failure telephone number generated during a broadcast transmission in a mobile communication terminal.

According to the present invention for achieving the above object, there is provided a method for retransmitting a broadcast short message in a mobile communication terminal, the step of transmitting the same short message to a plurality of counterpart phone numbers in sequence during the broadcast transmission, the broadcast transmission During the transmission failure, storing the failed transmission telephone number in a failed telephone number list, transmitting the short message to a next counterpart telephone number, determining whether there is a failed transmission telephone number after the broadcast transmission is completed; Exaggerating displaying a message requesting retransmission if there is a failed transmission number, displaying the telephone numbers stored in the failed telephone number list when selecting the retransmission, and entering the confirmation key during the display. Resending the short message to the phone numbers stored in the number list. It is characterized by including.

In addition, the radio frequency unit (RF) 320 lowers the radio frequency signal received through the antenna 318 to the baseband processor 322, and provides the baseband signal from the baseband processor 322. The frequency is raised and transmitted through the antenna 318. The baseband processor 322 processes the baseband signal transmitted and received between the RF unit 320 and the control unit 300. For example, in case of transmission, channel coding and spreading of data to be transmitted are performed, and in case of reception, despreading and channel decoding of a received signal are performed. . That is, the baseband processor 322 is a block for demodulating various channels (calling channel, traffic channel, etc.) received from the base station or generating various channels (access channel, traffic channel, etc.) transmitted to the base station.

4 is a diagram showing screens displayed when performing broadcast transmission in the present invention. Looking at the broadcast transmission process with reference to FIG. 4 as follows.

First, (a) shows the "message management" window displayed when the user enters the text transmission key. The message management window includes a plurality of selection items. When the user selects item 2 on the screen (a), the terminal displays the "outgoing message" window as shown in the screen (b). Again, if item 1 is selected on the screen (b), the terminal displays the "Write Letter" window as shown in the screen (c). Here, when the user selects item 1 (write a new sentence), the terminal displays a sentence editing window (not shown), and the user inputs a sentence by operating a keypad. After inputting the sentence and inputting the confirmation key, as shown in (d), a message asking whether to keep the sentence is displayed. At this time, if the user selects a sentence storage (Yes), the input sentence is stored in the corresponding area of the memory. After the sentence is stored, the terminal displays a window for entering a relative number as shown in (e) screen. At this time, the user inputs a plurality of telephone numbers for broadcasting. After inputting the plurality of telephone numbers and inputting a confirmation key, the terminal displays a window for inputting a number to be contacted as shown in (f) screen. At this time, the user inputs a telephone number to be contacted by operating the keypad.

If the confirmation key is input after the telephone number to be contacted is input, (g) a display showing the progress of the transmission is displayed as shown on the screen, and the short message is sequentially transmitted to the plurality of telephone numbers. In this case, when the terminal transmits a short message to a specific telephone number and receives an ACK from the system (if the transmission is successful), the terminal transmits the short message to the next telephone number. When all of the short messages are transmitted to the plurality of phone numbers, the terminal displays a message asking whether to store the outbox as shown in (h) screen. At this time. If the user selects Save Outbox (Yes), the terminal saves the information of the last short message sent (short message (sentence) + last sender's number + number to be contacted) in the corresponding area of memory and displays the standby screen. If not, select "No" to display the standby screen immediately.

On the other hand, if a transmission failure occurs during the broadcast transmission, the terminal skips the failed transmission telephone number and transmits a short message to the next telephone number. After the short message is transmitted to the last phone number in this manner, if any one of the broadcast transmission phone number transmission failures occurs, the terminal displays a message asking whether to resend together with the failure message as shown in (i) screen. At this time, if the user selects retransmission (Yes), a list of failed transmission telephone numbers is displayed as shown in (k) screen. When the user inputs a confirmation key, the screen (g) is displayed again and broadcast transmission is performed again with the list of the failed transmission numbers. On the other hand, if the user selects "No" in the screen (i), the terminal displays a message asking whether to save the pending as shown in the screen (j). In this case, if the user selects 'Save Hold' (Yes), the terminal saves the short message (sentence), the list of unsuccessful phone numbers and the number to be contacted in the corresponding area of the memory and displays the standby screen. Select to display the standby screen immediately.

5A and 5B illustrate a procedure for retransmitting a short message to a transmission failure telephone number generated during broadcast transmission in a mobile communication terminal according to an embodiment of the present invention.

5A and 5B, the controller 300 first checks whether a short message transmission key is input in step 501. If the short message transmission key is not input, the control unit 300 proceeds to step 505 to perform the corresponding mode. If the short message transmission key is input, the control unit 300 proceeds to step 503 and displays a sentence editing window on the display window, and displays a sentence (short message) input by the user in step 507.

In operation 509, the controller 300 checks whether a confirmation key is input by a user's key operation. If the confirmation key is not input, the control unit 300 returns to step 507 and displays a sentence to be input. If the confirmation key is input, the control unit 300 displays a "counter party number input" window in step 511 and displays a number input by the user in step 513. The counterpart number input window is implemented to input a plurality of telephone numbers as shown in FIG. The controller 300 checks whether the confirmation key is input in step 515. If the confirmation key is not input, the control unit 300 returns to step 513 and displays the input number.

If the confirmation key is input, the controller 300 displays a window for inputting a number to be contacted in step 517 and displays a number input by the user in step 519. The controller 300 checks whether the confirmation key is input in step 521. If the confirmation key is not input, the control unit 300 returns to step 519 and displays the input number.

If the confirmation key is input, the controller 300 stores the number of phone numbers entered in the counterpart number input window in the variable "N" in step 523 and initializes the variables n and m to '0'. Here, "n" is a variable for counting the number of failed transmission telephone numbers, and "m" is a variable for counting the number of successful transmission telephone numbers. On the other hand, the telephone numbers input in the counterpart number input window are stored in the broadcast transmission telephone number list. After setting the variables as described above, the control unit 300 displays a display (g) of FIG. 4 showing the transmission progress in step 525.

In operation 527, the controller 300 formats the short message according to the transmission standard to transmit the short message to the first counterpart number, and transmits the short message formatted according to the transmission standard to the SMSC 71. The controller 300 checks whether a response ACK is received from the SMSC 71 for a preset time in step 529. If the response is not received, the control unit 300 proceeds to step 549 and increases the variable m representing the number of failed transmission phone numbers by '1', and transmits a short message to the next counterpart number in step 527. Go back and perform the following steps again. If the response is received, the control unit 300 deletes the successfully transmitted telephone number from the broadcast transmission telephone number list in step 531 to create a list of failed transmission telephone numbers, and in step 533, the variable n indicating the number of successful transmission telephone numbers. Is increased by '1'.

In operation 535, the controller 300 compares the value obtained by adding the n value with the m value and the N value to determine whether the same value is the same. That is, it is determined whether all short messages are transmitted to the telephone numbers stored in the broadcast transmission telephone number list. If it is not the same, the control unit 300 returns to step 527 to perform the next step again to continue transmitting the short message to the next counterpart number. If the same, the controller 300 checks whether the m value is greater than or equal to '1' in step 537. In other words, it checks whether there is a transmission failure.

If the m value is greater than or equal to '1', the controller 300 displays a message (i) of FIG. 4 asking whether to retransmit in step 539. In operation 541, the controller 300 determines whether retransmission (Yes) is selected by the user's key operation.

If the retransmission is not selected, the control unit 300 displays a message (j) of FIG. 4 asking whether the reserved midnight is in step 543. In operation 545, the controller 300 checks whether storage (eg) is selected by a user's key manipulation. If the save storage is selected, the control unit 500 stores the short message (sentence), the unsuccessful transmission number, and the number to be contacted together in step 547, and then terminates the storing. The control unit 300 immediately ends.

If retransmission is selected in step 541, the controller 300 displays a counterpart number input window including m phone numbers that failed to be transmitted in step 551. The controller 300 checks whether the confirmation key is input in step 552. When the confirmation key is input, the control unit 300 returns to step 523 and resets the variables N, n, and m and performs the following steps again. At this time, the broadcast number list is updated with the m numbers.

On the other hand, if the m value is less than '1', the control unit 300 displays a message (Fig. 4 (h)) asking whether to save the outbox in step 553. In operation 555, the controller 300 checks whether storage (Yes) is selected by the user's key operation. If the outbox storage is selected, the control unit 300 stores the information of the short message (including the sentence + the last transmitting party number + the number to be contacted) sent in step 557 in the outbox and terminates, otherwise, "no" is returned. Quit as soon as it is selected.

As described above, in the present invention, when a transmission failure occurs during a broadcast transmission, the failed transmission telephone number is skipped and a short message is transmitted to the next telephone number. In this way, the short message is sent to the last phone number. On the other hand, the number of successful transmissions during the phone number is deleted from the broadcast transmission telephone number list to generate a list of transmission failure telephone numbers. As another example, a method of storing a failed transmission number separately may be used. If the failed transmission number is '1' or more, a message asking for retransmission with a failure message is displayed, and if the user selects retransmission, the short message is retransmitted to the failed transmission numbers. Although the above-described embodiment has been described as asking whether to retransmit and displaying a list of failed transmission numbers, it is also possible to display a list of failed transmission numbers first and ask whether to resend.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

As described above, since the present invention automatically generates a list of failed transmission telephone numbers during broadcast transmission, it is advantageous in that retransmission can be simply performed only on the failed transmission telephone numbers. In this case, it is possible to eliminate the financial loss and inconvenience in use, which has been a problem in the past. Even if the retransmission is not immediately performed and stored in the pending list, the stored number is stored together with the failed transmission number list, so that the user can easily transmit a short message later without inputting the telephone number. In addition, as an invention that satisfies the needs of the user, it is possible to expect the effect of sales promotion through strengthening the competitiveness of the product.
