Figure 4 is a flow chart of the method of importing according to a preferred embodiment of the present invention.

The present invention relates to a portable terminal, and more particularly to a portable terminal for transmitting a large amount of messages through the portable terminal.

The rapid development of the portable terminal not only improves the communication quality through the portable terminal, but also increases the performance of the processor and memory resources of the portable terminal, thereby providing various functions as well as communication.

Furthermore, as the multimedia message service (MMS), the multimedia mail service, and the multimedia content service through the portable terminal are realized, download and upload of a large amount of data, mail, multimedia contents, etc. through the portable terminal are required. .

For the reason described above, when a large amount of messages are transmitted to the server side, transmission of the messages may be interrupted due to network and system status, mail transmission server status or user cancellation.

In such a case, it is very inefficient to retransmit all of the large amount of data, and conventionally, a technique for continuously transmitting data from the interrupted portion has been proposed.

As the above technology, there is a patent application No. 10-2002-0012521 entitled "Data transmission method using a mobile communication terminal" in the Republic of Korea Patent Office. In the above-described technology, when data transmission is interrupted due to network disconnection, crosstalk, system abnormality, etc. during the wireless transmission of data to the server side using a mobile communication terminal, the data can be started from the data at the point where the transmission was interrupted. It is. According to this, if data transmission from the mobile communication terminal to the server side is interrupted, the server determines whether the terminal is connected to the network, and transmits a subsequent request message; Receiving a second request message from the terminal and notifying the user of the second request message; A third step of transmitting, at a terminal, a user's selection result for the resume request message to a server; A fourth step of, when the user selects to send, the terminal performs sending to the server, and the server attaches and stores the received data to the previously received data; If the user does not choose to continue the transmission, the server deletes the previously stored data, the terminal is characterized in that the fifth step of terminating the transmission.

The above-described prior art is a reason for causing an overload on the server performing communication with a large number of portable terminals by checking whether or not the server is connected with the portable terminal and performing the resending.

Therefore, unlike the prior art, it is urgently needed to develop a technology capable of transferring large amounts of data without causing an overload on the server.

An object of the present invention is to provide a portable terminal capable of overcoming the above-mentioned conventional problems and allowing a portable terminal to check a connection state with a server and continue sending a message that has been discontinued.

In order to achieve the above object, the portable terminal according to the present invention, the portable terminal, the communication unit in charge of communication with the server; A memory unit for storing a message; And a control unit for connecting to the server and transmitting a message from the portion where the transmission of the message is interrupted to the server when a request for resuming the transmission of the message is stopped during transmission to the server. It is done.

In addition, the information on the transmission stop portion is provided from the server, or when the transmission of the message is characterized in that stored in the portable terminal.

In addition, the controller checks whether the server supports resumption, if the server does not support retransmission, retransmits the entire message, and if the server supports resumption, the transmission of the message is stopped. It is characterized by transmitting a message from the server.

The resending may be performed a predetermined number of times at predetermined time intervals.

In another preferred embodiment, a portable terminal comprising: a communication unit in charge of communication with a server; A memory unit for storing a message; During transmission to the server, if a request for resumption of the message whose transmission has been stopped is requested, the server is connected with the server to provide identification information on the message, and the transmission stop portion for the message corresponding to the identification information is transmitted. When the information is received from the server, according to the information on the transmission stop portion, characterized in that it comprises a control unit for transmitting a message from the transmission stop portion of the message to the server.

In addition, when the transmission stops the message, the control unit stores the information on the transmission stop portion of the message in the memory unit, the information on the transmission stop for the message provided from the server and the stored information is the same If the two pieces of information are the same, the message from the transmission stop portion of the message is transmitted to the server.

The present invention allows the portable terminal to check the connection state with the server and continue sending data that has been stopped.

A schematic configuration of a portable terminal to which the present invention described above is applicable will be described with reference to FIG. 1.

The control unit 102 of the portable terminal 100 not only controls the portable terminal 100 as a whole, but also includes a message transmission module such as a mail client for performing a message transmission according to a preferred embodiment of the present invention. .

The memory unit 104 stores a variety of information including the processing program of the control unit 102, and in particular, message transmission information corresponding to a message is stored according to a preferred embodiment of the present invention. The message may be a large amount of data or mail. Also, the message transmission information includes retry count information, transmission count information, last transmission time information, message identification information, transmission message offset value, and transmission message size information as shown in FIG. It is stored corresponding to the message.

The resume timer 106 is used to determine a point in time at which a corresponding message is to be transmitted when a transmission fails. When a predetermined time is counted, an interrupt timer generates an interrupt for initiating the transmission to the message transmission module.

The retry counter 110 counts the number of attempts to resend under the control of the message transmission module of the controller 102.

The communication unit 108 is responsible for communication between the message server for transmitting and receiving messages and the message transmission module of the control unit 102 through a wireless network or the like.

The message server may use various types of protocols, such as a simple mail transfer protocol (SMTP) and an extended SMTP (ESMTP), in the Internet for the purpose of message transmission.

The SMTP server 112 receives a message from the portable terminal 100 and provides the message to a designated mail account.

Now, a message transmission method applicable to the portable terminal will be described schematically with reference to the procedure diagram of FIG.

When the data transmission module included in the controller 100 succeeds in accessing the SMTP server 112, the data transmission module transmits an EHLO command to the SMTP server 112 (S1). Upon receiving the EHLO command, the SMTP server 112 transmits a response code including information indicating whether to support the return indicated by a CHECK POINT to the data transmission module (S2).

The data transmission module receiving the response code transmits the message identification information of the message to be transmitted to the SMTP server 112 when the SMTP server 112 supports the resume function (S3). The data is sent to the SMTP server 112 in the section TRANSID (S4). The SMTP server 112 transmits a response code to the data transmission module after storing the message identification information included in the transmission identification information section of the message transmission command (S5, S6).

Thereafter, the data transmission module and the SMTP server 112 transmit the message through a procedure such as RCPT, response, message transmission, response, and QUIT (S7 to S12).

If the transmission of the message is interrupted due to network disconnection, crosstalk, system failure, etc. during the transmission of the message, the data transmission module provided in the control unit 102 of the portable terminal 100 attempts to connect the SMTP server 112 every predetermined time. To implement the redirection of the message.

A method for carrying over a message according to a preferred embodiment of the present invention will be described in more detail with reference to FIG. 4.

The data transmission module included in the control unit 102 of the portable terminal 100 initiates a resumption procedure when an interrupt occurs as a user's command or a retry timer counts a predetermined time through a user interface (not shown). (Step 200).

The data transmission module reads the message transmission information and the message for the message to be sent from the memory unit 104 and accesses the SMTP server 112 (steps 204 and 206).

When the SMTP server 112 provides a response code including information on whether to support the resumption according to the connection attempt of the SMTP server 112, the data transmission module refers to the response code and the SMTP server 112. In step 208, it is checked whether or not to support resending.

If the SMTP server 112 supports subsequent transmission, the data transmission module inserts the message identification information into the transmission identification information of the message transmission command and transmits the message identification information to the SMTP server 112 (step 210).

Here, the SMTP server 112 receiving the message transmission command in which the message identification information is inserted transmits an acceptance response to the data transmission module by putting a last offset value of the corresponding message in a response code, or rejects the resending response. It can be transmitted to the data transmission module.

When the response code is received from the SMTP server 112, the data transmission module checks whether the response code is an acceptance response or a rejection response of the transmission (step 212).

If the SMTP server 112 provides an acceptance response code including an offset value, the data transmission module transmits a message from the information field after the offset value to the SMTP server 112 (step 216). .

When the transmission in step 216 is completed (step 218), the data transmission module updates the message transmission information on the transmitted message to the completion of transmission and terminates the connection with the SMTP server 112 (steps 220 and 222).

If the transmission is interrupted in step 218 without completing the data transmission module, the data transmission module increases the count value of the resume counter 110 in the corresponding message transmission information (step 224), and the increased resume count value is predetermined. If it is determined that the value is equal to or greater than the value of the resume count (step 226), the message transmission information for the corresponding message is updated to the message transmission failure and the connection with the SMTP server 112 is terminated (step 220, 222). .

Unlike the above, if the count value is less than the predetermined value, the data transmission module drives the resume timer 106 to start the resume procedure of the present invention after a predetermined time elapses (step 228).

In addition, if the SMTP server 112 does not support resumption (step 208), or rejects the resumption request from the data transmission module (step 212), the data transmission module retransmits the entire message and then 218. Step 214 is entered.

In the above-described embodiment of the present invention, the transmission is performed by referring to only the offset value provided from the SMTP server 112, but the portable terminal 100 is considered in order to consider the load of the SMTP server 112 and simplify the data transmission procedure. You can use the offset value stored in the) to perform the resume.

In addition, for synchronization between the SMTP server 112 and the portable terminal 100, it is necessary to check whether two offset values stored in the SMTP server 112 and the portable terminal 100 are the same to transmit a message. It may be.

In addition, the embodiments of the present invention include a computer readable medium including program instructions for performing operations implemented by various computers. The computer readable medium may include program instructions, data files, data structures, etc. alone or in combination. The program instructions on the medium may be those specially designed and constructed for the present invention, or they may be of the kind well-known and available to those skilled in the computer software arts.

As described above, the present invention has an effect of reducing the load on the server for resending the message by sending a message that is stopped by the portable terminal to check the connection state with the server.

Although the present invention as described above has been described by way of limited embodiments and drawings, the present invention is not limited to the above embodiments, which are those skilled in the art to which the present invention belongs, various modifications and Modifications are possible.
