Abstract:
A method of transmitting one text message to a plurality of receivers is disclosed. The method includes inputting numbers of the receivers and a text message to be transmitted, determining a type of a transmission speed of the inputted text message, and transmitting the inputted text message of the determined type to numbers of the respective receivers. If the text message transmission succeeds, the method further includes confirming whether any further receivers of the text message exist and, if so, inputting new numbers of the further receivers and re-transmitting the corresponding text message to the new numbers of the further receivers. In inputting the phone numbers of the receivers, the sender can transmit the text message more rapidly and conveniently using the phonebook function and one-touch dial function.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a text message transmitting method and, more particularly, to a method of transmitting one text message to a plurality of receivers.  
         [0003]     2. Background of the Related Art  
         [0004]     As the use of mobile communication terminals, such as cellular phones, PCS phones, personal digital assistants (PDAs), etc., increases with the development of mobile communication techniques, diverse additional services using the mobile communication terminal, such as voice message services, radio data communication services, text message services, etc., have been developed. Among them, the text message service has become a more important message transferring method than the voice call service, with respect to youngsters in their teens and twenties. Also, in order to satisfy the consumers&#39; tastes and to improve the quality of service, communication service providers and terminal manufacturers have made a great investment in the development of diverse services and the manufacture of terminals having more useful functions.  
         [0005]      FIG. 1  is a flowchart illustrating a related art text message transmitting process for a mobile communication terminal. A sender selects a text message function from a function selection menu that is displayed on a screen of the terminal. The sender then prepares a text message to be transmitted with a phone number of the terminal that is intended to receive the message (step S 100 ).  
         [0006]     Thereafter, it is determined whether to store the prepared text message (step S 110 ). If the sender intends to store the message, he/she selects a “message storage” command on a display section of the screen and the text message is stored in a memory (step S 120 ). Then, the sender selects one of the message transmission types, which are classified into normal, urgent, and special (step S 130 ), and the preparation of the text message transmission is completed. A message appears on the display section of the terminal (e.g., “Transmission?”) prompting the sender for a command to initiate the text message transmission (not illustrated).  
         [0007]     If the text message is transmitted (step S 140 ), the sender terminal, after several seconds, receives a response signal indicating the result of transmission from a message transmission center. The sender terminal analyzes the response signal and judges whether the transmission succeeded (step S 150 ).  
         [0008]     If the text message transmission succeeded, the sender terminal displays a message (e.g., “Transmission has been completed”) to inform the sender of the successful transmission and returns to an idle mode (steps S 170  and S 180 ). If the text message transmission failed, the sender terminal displays a message (e.g, “Retransmission?”) asking the sender whether to retransmit and also displays a message (e.g., “Transmission failed”) to inform the sender of the transmission failure (step S 160 ). The sender terminal then waits for the sender&#39;s command for retransmission.  
         [0009]     The retransmission process performed as a result of the transmission failure includes transmitting the prepared text message, receiving the response signal from the message transmission center (step S 140 ), and judging whether the transmission succeeded by analyzing the response signal (step S 150 ). These steps (S 140  and S 150 ) are repeated until the text message is successfully transmitted. However, if the sender does not want the retransmission, the sender terminal returns to the idle mode (step S 180 ).  
         [0010]     Consequently, when one text message is transmitted to a plurality of receivers, the sender should repeat the above steps (steps S 100  to S 180 ) for each receiver. For each receiver that is to receive the text message, the sender inputs the respective receiver&#39;s phone number during a separate execution of process steps S 100  to S 180 .  
         [0011]     As described above, according to the related art text message transmission method, the sender should repeat a series of processes, such as inputting the respective receiver&#39;s phone number, the text message, the message transmission type (i.e., “normal”, “urgent”, or “special”), and the transmission command, for each separate recipient receiver when transmitting the text message to a plurality of receivers. This causes inconvenience for the sender and makes it difficult to achieve a rapid transmission of the text message.  
       SUMMARY OF THE INVENTION  
       [0012]     An object of the invention is to solve at least the above problems and/or disadvantages and to provide at least the advantages described hereinafter.  
         [0013]     A further object of the invention is to provide a method of transmitting one text message to a plurality of receivers that enables a collective transmission of the text message.  
         [0014]     A further object of the invention is to reduce the input operations needed to identify the receivers.  
         [0015]     In accordance with the present invention, these objects are accomplished in whole or in part by providing a method of transmitting one text message to a plurality of receivers. The method includes inputting numbers of the receivers and a text message to be transmitted; determining a type of a transmission speed of the inputted text message; and transmitting the inputted text message of the determined type. If the text message transmission succeeds, the method further includes confirming whether any further receivers of the text message exist. If further receivers exist, the method further includes inputting new numbers of the corresponding receivers and re-transmitting the text message to the newly identified receivers. The method according to the present invention may further comprise returning to an idle mode if no further receivers exist.  
         [0016]     Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objects and advantages of the invention may be realized and attained as particularly pointed out in the appended claims.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
       [0022]      FIG. 2  is a flowchart illustrating a text message transmission process for a mobile communication terminal according to the present invention. A sender inputs phone numbers of the recipient receivers, after selecting a text message function from a function selection menu of the terminal (step S 200 ). The phone numbers of the receivers are inputted using a phonebook function. The phonebook function is a basic function of the terminal set to enable the storage, deletion, and editing of phone numbers. The phonebook function is implemented at the receiver&#39;s number input step (step S 200 ). For the collective transmission of the text message to many receivers, the corresponding phone numbers are inputted at the receiver&#39;s number input step (step S 200 ).  
         [0023]     After the phone numbers of the receivers are inputted, the sender prepares the text message (step S 200 ) and then determines whether to store the prepared message (step S 210 ). Then, the sender selects one of the message transmission types, which are classified into normal, urgent, and special transmission (step S 230 ), to complete the preparation of the text message transmission. A message appears on a display section of the terminal screen (e.g., “Transmission?”) prompting the sender to enter a text message transmission command (not illustrated).  
         [0024]     If the text message is transmitted, the sender terminal, after several seconds, receives a response signal from a message transmission center (step S 240 ). The sender terminal analyzes and judges whether the transmission succeeded based on this response message (step S 250 ). The sender terminal displays a message to inform the sender whether the transmission succeeded. If the text message transmission failed, the sender terminal displays a message (e.g., “Transmission failed. Retransmission?”) asking the sender whether to retransmit the text message and waits for the sender&#39;s command (step S 260 ). If the sender commands the retransmission, the sender terminal feeds back to step S 240  and retransmits the prepared text message. This retransmission process (steps S 240 -S 260 ) is repeated until the text message is successfully transmitted. If the sender does not want the retransmission, the terminal returns to the idle state.  
         [0025]     If the transmission of the text message succeeds, the sender terminal displays a message (e.g., “Transmission succeeded. Do any further receivers exist?”) asking the sender whether any further receivers shown on the display section are to receive the text message. Thereafter, the sender terminal waits for the sender&#39;s command (step S 270 ).  
         [0026]     If no further receivers are intended to receive the text message, the sender terminal terminates the text message transmission process and returns to the idle mode (step S 290 ). However, if further receivers exist to which the text message is to be transmitted, the sender terminal receives the input of phone numbers of the corresponding receivers (step S 280 ). At this time, the receiver phone number input process is the same as the receiver phone number input of step S 200 .  
         [0027]     If the phone numbers of the new receivers are inputted, a message (e.g., “Retransmission?”) appears on the display section of the sender terminal and the sender terminal waits for the sender&#39;s command of text message transmission (not illustrated). When the command is received, the sender terminal repeats the above steps S 240 , S 250 , and S 270 .  
         [0028]     If any further receivers to which the text message is to be transmitted exist after the completion of the collective transmission to the plurality of receivers, the sender terminal performs the text message transmission steps S 280 , S 240 , S 250 , and S 270  successively. Also, the phone numbers of the receivers are more easily inputted through the application of the existing one-touch dial function of the terminal (i.e., the function of inputting recently used phone numbers by pressing specified buttons), as described above.  
         [0029]      FIG. 2A  illustrates a flowchart of a text message transmission process for a mobile communication terminal, according to a second preferred embodiment of the present invention. The flowchart of  FIG. 2A  is similar to that of  FIG. 2 . For brevity, only a description of the dissimilarities will be provided below;  
         [0030]     Step  280  of  FIG. 2A  provides the sender the opportunity to send the message to additional receivers, as is the case for the process of  FIG. 2 . However, in this second embodiment, the process transitions to step  230 , after the entry of the identifications for the additional receivers. Step  230  provides the sender the opportunity to select the message transmission type for the additional receivers. Once the sender selects the message transmission type for these additional receivers, the text message is transmitted to the additional receivers using the corresponding message transmission type (S 250 ).  
         [0031]      FIG. 3  illustrates a flowchart of a text message transmission process for a mobile communication terminal, according to a third preferred embodiment of the present invention. After selecting a text message function from a function selection menu of the terminal, a sender inputs the text message intended for transmission to a number of receivers (S 310 ). Upon completing the entry of the text message, the sender is prompted by a display on the terminal screen to enter a command indicating whether the text message should be stored to memory. If the sender commands the terminal to store the text message, it is stored to memory (S 220 ) and the transmission process continues with step S 320 . Otherwise, the transmission process continues with step S 320  without storing the text message to memory.  
         [0032]     The sender is prompted to enter the phone number (i.e., identification) of a receiver that is intended to receive the text message, using the phonebook function of the terminal. After the sender identifies a receiver (S 320 ), the terminal prompts the sender to select a message transmission type for the identified receiver. When the sender selects the message transmission type (e.g., normal, urgent, and special), the terminal prompts the sender to enter a command instructing it whether to continue with the entry of receiver identifications (S 340 ). If the sender instructs the terminal to continue the process of identifying receivers of the text message, the transmission process transitions to step S 320 . Otherwise, the transmission process continues by transmitting the text message to the collective group of identified receivers (S 240 ). Process steps S 320 , S 330 , and S 340  are repeatedly performed until all of the intended text message recipients have been identified.  
         [0033]     If the text message is successfully transmitted, the sender terminal receives a response signal from a message transmission center, after several seconds (step S 240 ). The sender terminal determines whether the transmission succeeded based on this response message (step S 250 ). The sender terminal displays a message to inform the sender whether the transmission succeeded. If the text message transmission failed, the sender terminal displays a message (e.g., “Transmission failed. Retransmission?”) prompting the sender to enter a command. If the sender commands the terminal to retransmit the text message, the terminal retransmits the text message to the recipient that failed to receive the text message previously (S 240 ). This retransmission process (steps S 240 -S 260 ) is repeated until the text message is successfully transmitted.  
         [0034]     If the sender commands the terminal not to retransmit the message or if the transmission of the text message to the collective group of recipients succeeds, the terminal provides the sender the opportunity to send the text message to additional receivers. The terminal displays a message (e.g., Do any further receivers exist?”) prompting the sender to enter a command. If the sender commands the terminal to terminate the transmission process, then the terminal returns to its idle mode of operation (S 290 ). Otherwise, the terminal prompts the sender to enter the identification of another receiver that is intended to receive the text message (S 320 ).  
         [0035]     According to the related art text message transmission method, the sender should repeat the message transmission process as many times as the number of the receivers, in such a manner that the sender inputs the phone numbers of the receivers one by one when the sender transmits one text message to a plurality of receivers. With the present invention, the performance of the above unnecessary process is avoided. To more effectively transmit the text message, the phone numbers of the plurality of receivers are inputted at the receiver number input step. Also, in inputting the phone numbers of the receivers, the sender can transmit the text message more rapidly and conveniently using the phonebook function and one-touch dial function.  
         [0036]     Also, by arranging the receiver number input process (steps S 200  and S 280 ) in front of and behind the text message transmission process (step S 240 ), the sequential transmission of the message becomes possible in addition to the collective transmission of the message.  
         [0037]     The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art. In the claims, means-plus-function clauses are intended to cover the structures described herein as performing the recited function and not only structural equivalents but also equivalent structures.
