Have

In addition, the operation control method of the portable terminal according to the present invention is applicable to an environment in which a signaling protocol such as a Session Initiation Protocol (SIP) or a messaging protocol such as a Message Session Relay Protocol (MSRP) is used. Here, MSRP is a protocol for an instant messaging service, and is a protocol proposed to compensate for the drawback that the instant messaging method using the existing MESSAGE method does not consider any relations between messages. Accordingly, in order to provide a SIP-based instant messaging service, two methods, a pager-mode method using a SIP extension method called MESSAGE and a message session establishment method using MSRP, are used.

Referring to FIG. 4, first, the first portable terminal 100 receives a file transmitted from the second portable terminal 200 (S300). In this case, the file may be a file received through an instant messaging service using MRSP.

When the first portable terminal 200 receives the file, the antivirus program is executed to perform a virus check on the received file (S305). If a virus is detected in the received file as a result of the virus scan, the first mobile terminal 100 reports the virus detection fact to a file transfer report message that reports a file transfer result such as whether the file was successfully received or failed to receive. Included and transmitted to the second portable terminal 200 (S310). If a virus is not detected as a result of the virus test, a file transfer report message indicating that the file was successfully received may be transmitted to the second mobile terminal 200.

In response to the transmission of the message including the fact that the virus has been detected, the second portable terminal 100 receives a request for virus information on the virus detected using the SIP INVITE message or the like (S315). The first portable terminal 200 accepts this (S320). In operation S325, a message including virus information about the detected virus is transmitted to the second mobile terminal 200. Accordingly, a file transfer report indicating that the file was successfully received from the second mobile terminal 200 is received (S330).

When a virus is detected in the received file by the above process, the virus may be included in the message reporting the file transfer result and transmitted to the terminal that has transmitted the file, so that necessary actions may be performed.

5 and 6 are flowcharts provided to explain an operation control method of a portable terminal according to an embodiment of the present invention. First, in FIG. 5, an operation process of a terminal that receives a file will be described.

Referring to FIG. 5, when a file is received from the second portable terminal 200 as the counterpart terminal (S400), the controller 180 executes an antivirus program and performs a virus check on the received file (S405).

As a result of the virus test, if a virus is detected in the received file (S410), the control unit 180 includes the virus detection fact in a message reporting the file transfer result and transmits it to the second mobile terminal 200 (S415). However, if a virus is not found as a result of the virus test, a message reporting a general file transfer result is transmitted to the second mobile terminal 200 (S420).

When the received file is a file received through an instant messaging service using a message session relay protocol (MRSP), an MSRP message may be used as a message for reporting a file transfer result. [Table 1] below shows an example of an MSRP message transmitting actual content.

Next, the controller 180 moves and stores the received file to the quarantine area preset in the memory 160 (S425). The file stored by moving to the quarantine area may be deleted or treated through a user's confirmation process. It is also possible to query whether the sample is to be sent to the vaccine company, and to send the sample to the vaccine company according to the response result.

The controller 180 displays the contents indicating the virus detection on the display unit 151 so that the user knows that the received file is virus infected (S430).

If there is a request for information on the detected virus from the counterpart terminal (S435), the controller 180 transmits a message including the virus information about the detected virus to the counterpart terminal (S440).

The request for virus information from the counterpart terminal may be transmitted through a SIP INVITE message. Session Initiation Protocol (SIP) is an application layer signaling protocol that can establish, modify, and terminate multimedia sessions. In addition, the INVITE message in the SIP Request message is generally a message sent by the client to the server when the session starts. In some cases, you can send directly to the other client. Table 3 below shows an example of a SIP INVITE message requesting virus information.

By this process, the fact of virus detection can be transmitted to the terminal which transmitted the file so that necessary measures can be taken.

6 is a flowchart illustrating an operation process at a terminal side that transmits a file. Referring to FIG. 6, the second portable terminal 200 transmits a file to the first portable terminal 100 (S450) and then receives a file transfer report from the first portable terminal 100 (S455).

When the second mobile terminal 200 receives the file transfer report message, the second mobile terminal 200 checks whether the virus detection is included in the message (S460). As a result of the virus detection, if the virus is detected, the virus information is requested to the first mobile terminal 100 (S465), and a message including the virus information is received (S470).

When the second portable terminal 200 receives the virus information, the second mobile terminal 200 updates the virus vaccine according to the received information (S475), and performs a virus test using the updated virus vaccine (S480). In the case of a virus scan, a virus scan may be performed on a mode file stored in addition to the transmitted file.

In addition, it is possible to notify the other terminal that transmits the same file or other files to the fact that the virus is detected so that the virus scan and treatment can be performed in that terminal. The terminal to be notified of the virus detection may be selected by referring to a call list, a message list, a contact list, a network connection history, and the like. The virus detection may be notified directly to the selected terminal, or a method of notifying the base station of the virus detection and notifying the other terminal from the base station may be used.

7A to 7C illustrate an example of a screen for detecting and processing a virus in a mobile terminal according to an embodiment of the present invention.

7A illustrates an operation screen 500 in a mode of receiving a file. If a virus is detected in the received file after file reception is completed in the mode of receiving such a file, as illustrated in FIG. 9B, the virus alert window 510 notifying the operation screen 500 that the virus is detected. Can be displayed as a transparent window.

If the virus alert window 510 is touched or long touched, the virus alert window 510 is activated and displayed as an opaque virus related menu window 520 as shown in FIG. 7C. When the user selects 'Delete' in the virus-related menu window 520, the file related to the virus infection operation is deleted. In addition, selecting 'Sending Sample' sends the sample to the vaccine company and selecting 'Ignore' ignores the virus infection.

Meanwhile, the present invention can be embodied as processor readable codes on a processor readable recording medium provided in a mobile terminal such as a mobile station modem (MSM). The processor-readable recording medium includes all kinds of recording devices that store data that can be read by the processor. Examples of the processor-readable recording medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, and the like, and may be implemented in the form of a carrier wave such as transmission through the Internet. The processor-readable recording medium can also be distributed over network coupled computer systems so that the processor-readable code is stored and executed in a distributed fashion.
