The present invention relates to a short message service (SMS) system, and more particularly to an improved message transmission method for providing a response function and a delivery function in a short message service of a wireless terminal.

In general, a short message service refers to a service capable of transmitting a short message between a user terminal and a voice mail server (via a short message service server), which is similar to a paging function in a pager. The current short message supports up to 160 characters.

Conventionally, such a short message service is processed in the terminal by the following procedure.

First, the terminal writes a short message to be transmitted using a character key in a user data field. Subsequently, the terminal inputs the telephone number into the source address field according to the short message service protocol format and transmits the telephone number to the counterpart phone number written in the destination address field. In contrast, the terminal can display only the message received from the other party in the same manner as the short message service transmission.

However, when a terminal receiving a conventional short message service modifies a received message, there is no modification function for the message and there is no retransmission function of the received message. You need to type in a number and send it to the phone number you want to send again. In addition, replies to the received messages must be retransmitted through the above procedure. Therefore, when the conventional short message service is used as it is, the user has to enter a character directly into the terminal, which has a problem of considerable time and hassle.

An object of the present invention is to provide a short message service method for improving user convenience by providing a reply function and a forwarding function for a short message received from a wireless terminal.

In order to solve the above technical problem, the present invention provides a short message service method,

(a) when the short message is received, determining a response mode or a retransmission mode according to the content of the message;

(b) where the short message protocol exchanges the recipient's telephone number and the calling party's telephone number in the short message protocol when the answer mode is determined in step (a), and transmits the short message when the short message protocol is determined in the retransmission mode. Sending a short message with your phone number,

In the response mode of step (b), the source address field and the destination address field are exchanged in the short message service protocol.

The retransmission mode of step (b) is a method of transmitting a short message, characterized in that the telephone number of the other party is input in the destination address field of the short message service protocol.
