Abstract

PURPOSE: A method for transmitting a short message in a mobile communication system is provided so that it is possible for a subscriber of an origination-side mobile communication terminal to know whether a termination-side mobile communication terminal receives a short message by transmitting a transmission success message or a transmission failure message to the origination-side mobile communication terminal according as a reception response message is received or is not received after transmitting the short message. CONSTITUTION: An SMC(Short Message Center) confirms whether a specific code is included in a termination number(103). If the specific code is included in the termination number, the SMC checks a reception confirmation field of a message queue(105). The SMC stores a short message in the message queue(107). The SMC transmits the short message to a corresponding termination-side mobile communication terminal(109). The SMC judges whether a reception response message is received from the termination-side mobile communication terminal(111). If the reception response message is received from the termination-side mobile communication terminal, the SMC confirms whether the reception confirmation field is checked(113). If the reception confirmation field is checked, the SMC transmits a transmission success message to an origination-side mobile communication terminal(115). If the reception response message is not received, the SMC judges whether the short message is repeatedly transmitted during a predetermined time(117). If the short message is repeatedly transmitted during the predetermined time, the SMC confirms whether the reception confirmation field is checked(119). If the reception confirmation field is checked, the SMC transmits a transmission failure message to the origination-side mobile communication terminal(121).

The BS 20, 60 communicates with the mobile communication terminals 10, 70 by using a wireless section, controls a wireless link and a wired link, and maintains the durability of a call even when a subscriber is moving. Perform the off function.

The MSC 30 interworks with other MSCs in order to process origination and reception requests from the mobile communication terminals 10 and 70, and inquires the subscriber to the HLR 40. In addition, when a short message is received from the mobile communication terminals 10 and 70, the message is transmitted to the SMC 50, and when the short message is received from the SMC 50, the message is sent to the BS 20 and 60 and the message is transmitted through a paging channel. It can be transmitted to the terminal (10, 70).

The HLR 40 is a medium-class computer which mainly performs a function of managing a mobile communication terminal subscriber. The HLR 40 stores subscriber information and location information of the mobile communication terminal, and enables routing of an incoming call.

The SMC 50 is an independent node and is connected to the HLR 40 and the MSC 30 to determine the location of the receiver and deliver a short message to the mobile subscribers. The SMC 50 stores and forwards the short message that is transmitted to the called-party mobile communication terminal that cannot be received at any moment when transmitting and receiving the short message for a predetermined time. When the SMC 50 receives the short message from the mobile communication terminals 10 and 70 through the BS 20 and 60 and the MSC 30, the SMC 50 stores the received short message in the message queue. In addition, the number of the called-party mobile communication terminal (hereinafter referred to as "called number") received with the short message is analyzed in conjunction with the HLR 40 to track the location of the corresponding mobile communication terminal and transmit the short message. The message queue has an acknowledgment field added in accordance with an embodiment of the invention. The acknowledgment field is a field for checking information on whether the called mobile communication terminal normally receives a short message transmitted from the calling mobile terminal. The structure of the message queue according to the present invention is shown in FIG. 2 is a diagram illustrating the structure of a message queue according to an embodiment of the present invention. As shown in FIG. 2, the message queue 80 includes a short message field 81 for storing a short message to be transmitted, a called number field 83 for storing a called number, and an acknowledgment field 85. FIG.

In the above mobile communication terminal system, a process of transmitting a short message according to the present invention is as follows. The calling mobile terminal 10 transmits the called number including the short message to be transmitted and the number corresponding to the predetermined specific code to the BS 20 according to the subscriber input. The specific code is added according to the present invention, and is a code for indicating a request for information on whether the called mobile communication terminal normally receives a short message to be sent by the calling mobile communication terminal and consists of arbitrary numbers or special characters. . The short message and the called number are transmitted to the SMC 50 through the BS 20 and the MSC 30. The SMC 50 analyzes the called number and checks whether the specific code is included. If the specific code is included, the SMC 50 checks the acknowledgment field and then through the MSC 30 and the BS 20, the corresponding mobile communication terminal 70. Send a short message to. The SMC 50 repeats the transmission of the short message until the reception response message, which is a response message to the normal reception of the short message, is received from the called-party mobile communication terminal 70 for a predetermined time. The SMC 50 transmits a transmission success message or a transmission failure message to the calling mobile terminal 10 according to whether the reception response message is received.

3 illustrates an operation of the SMC 50 according to the short message transmission process as described above. 3 is an operation flowchart of a short message center according to an embodiment of the present invention. As shown in FIG. 3, the SMC 50 receives the short message to be sent from the MSC 30 from the MSC 30 in step 101 and proceeds to step 103. In step 103, the SMC 50 checks whether the specific code is included in the called party. If the specific code is included, the SMC 50 proceeds to step 105. If the specific code is not included, the SMC 50 proceeds to step 107. In step 105, the SMC 50 checks an acknowledgment field of the message queue and proceeds to step 107. In step 107, the SMC 50 stores the short message in the message queue and proceeds to step 109. In step 109, the SMC 50 transmits a short message to the called party's mobile communication terminal 70. The mobile communication terminal 70 transmits a reception response message when the short message is normally received. Thereafter, in step 111, the SMC 50 determines whether a reception response message has been received from the called party's mobile communication terminal 70, and if so, proceeds to step 113. If not, the SMC 50 proceeds to step 117. In step 113, the SMC 50 checks whether the acknowledgment field is checked, and if so, proceeds to step 115; otherwise, the SMC 50 proceeds to step 123. In step 115, the SMC 50 transmits a transmission success message to the calling mobile communication terminal 10 and proceeds to step 123. In step 123, the SMC 50 deletes the stored short message and terminates the short message transmission process. When the calling mobile communication terminal 10 receives the transmission success message, for example, "XXX-XXX-XXXX sends a message." Is received. "Is displayed.

3, if the reception response message is not received in step 111, the SMC 50 proceeds to step 117 to determine whether the short message is repeatedly transmitted for a predetermined time. The SMC 50 proceeds to step 119 if it is repeatedly transmitted for a predetermined time in step 117 and proceeds to step 109 if it is not repeatedly transmitted for a predetermined time. In step 119, the SMC 50 checks whether the acknowledgment field is checked, and if so, proceeds to step 121, and if not, proceeds to step 123. In step 121, the SMC 50 transmits a transmission failure message to the calling mobile terminal. That is, if a short response message is not received even after repeatedly transmitting the short message to the called mobile communication terminal for a preset time, the message "XXX-XXX-XXXX did not receive the message" is sent to the calling mobile communication terminal. Send a failure message.

Thereafter, the short message stored in step 123 is deleted and the short message transmission process ends.
