4 is a view for explaining a structure of virus pattern data used in a method of controlling an operation of a portable terminal according to the present invention. In the present invention, virus pattern data corresponding to a global pattern is loaded in the portable terminal, and virus pattern data corresponding to a local pattern is additionally loaded or deleted as needed.

Referring to FIG. 4, the virus pattern data 200 used for virus detection is classified into a global pattern 210 and local patterns 220a to 220d. Although only four local patterns 220a to 220d are illustrated in FIG. 4 for convenience, the local patterns 220a to 220d may be larger or smaller in actuality.

The global pattern 210 refers to virus pattern data loaded in the portable terminal 100 at the time of initial shipment or unpacking. The local patterns 220a to 220d are virus pattern data that can be additionally mounted or deleted depending on the operating environment, use of additional services, and the like.

In the case of V3, which is famous for the existing PC, the size of the vaccine program provided as a command prompt version excluding the user interface is about 70MByte. Most of them are virus pattern data, and it is impossible to mount them in the portable terminal 100 if they have all of them. That is, in the general portable terminal 100, the memory size of the premium class model is 512 MByte, and in the case of the general model, 128 MByte, the space of 10% or more in the entire memory can not be allocated to the vaccine program. Moreover, the size of the vaccine program is not possible because the size of the vaccine program becomes larger as the virus type increases.

Therefore, in the present invention, basically necessary virus pattern data is loaded, and if necessary, virus pattern data corresponding to a local pattern is added or deleted. The global pattern 210 and the local patterns 220a to 220d may be classified according to various criteria. For example, the global pattern 210 is virus pattern data for detecting viruses that are infected through the Internet, and the local pattern 220 is data on a limited platform such as a Wireless Internet Platform for Interoperability (WIPI) and a Binary Runtime Environment for Wireless Virus pattern data for detecting a virus that operates or attacks a specific service of a specific provider, and the like.

5 is a flowchart illustrating a method of controlling an operation of a mobile terminal according to a first embodiment of the present invention. Referring to FIG. 5, first, a global pattern is determined among virus pattern data (S300), and virus pattern data corresponding to the determined global pattern is loaded into the memory 160 (S305).

The control unit 180 performs a virus check using the virus pattern data corresponding to the global pattern loaded in the memory 160 (S310). When a virus infection operation is detected as a result of the virus scan, the infection operation can be blocked, the file corresponding to the infection operation can be isolated, or can be treated by a vaccine program or the like. At this time, a message indicating that the virus infection operation is detected can be displayed.

If the operating environment is changed (S315) while the virus pattern is being executed using the global pattern, the virus pattern data corresponding to the local pattern corresponding to the changed operating environment is downloaded (S320). When the virus pattern corresponding to the local pattern is downloaded, a message indicating that the virus pattern data has been updated may be displayed.

The local pattern may be determined according to a Mobile Country Code (MCC) and a Mobile Network Code (MNC) having different values depending on a terminal platform, a country and a provider. The virus pattern data corresponding to the local pattern may be loaded at the time of factory manufacture or at the time of initial power-on, the MCC and MNC may be received through the SIB, and a local pattern corresponding thereto may be downloaded using OMA SCOMO (Software Component Management Object) have. A local pattern is added to the global roaming, and the previously used local pattern can be deleted.

After downloading the local pattern, the control unit 180 executes the virus check using the virus pattern data corresponding to the global pattern and the local pattern (S325). Likewise, if a virus infection operation is detected as a result of the virus check, the infection operation can be blocked, the file corresponding to the infection operation can be isolated, or can be treated by a vaccine program or the like.

If the added local pattern becomes unnecessary (S330), the control unit 180 deletes the virus pattern data corresponding to the local pattern in the memory 160 (S335).

With this process, virus pattern data corresponding to a local pattern can be additionally used or deleted as needed to prevent virus infection in various operating environments.

6 is a flowchart illustrating a method of controlling an operation of a portable terminal according to a second embodiment of the present invention. In this embodiment, a process of adding virus pattern data when subscribing to an additional service such as E-mail, MMS, RIM, etc., uniquely provided for each provider will be described.

Referring to FIG. 6, an additional service subscription such as MMS (Multimedia Messaging Service) or e-mail is requested (S350), and when the subscription of the supplementary service is approved (S355) The virus pattern data is downloaded (S360). For example, when subscribing to the MMS service, the software for driving the MMS and the virus pattern data related to the MMS are downloaded. At this time, OMA SCOMO can be used for downloading virus pattern data and the like.

The control unit 180 performs a virus check using the virus pattern data loaded and the virus pattern data corresponding to the downloaded local pattern (S365). If a virus infection operation is detected as a result of the virus scan, the infection operation can be blocked, files corresponding to the infection operation can be isolated to a quarantine area, or the virus can be treated by a vaccine program or the like.

If the use of the supplementary service is terminated (S370), the downloaded local pattern is unnecessary. Therefore, the control unit 180 deletes the virus pattern data corresponding to the downloaded local pattern (S375).

With this process, instead of loading all the virus pattern data from the beginning, the necessary virus pattern data can be downloaded and used according to the use of a new supplementary service or the like.

7 is a table showing an example of a criterion for dividing a local pattern. Referring to FIG. 7, the portable terminal may classify patterns based on MCC and MNC received from the network, or may be a hardware platform such as a smart phone, a feature phone, a Symbian, a WM, a Linux, an OEM, JAVA, WIPI and other software platforms, services, and so on.

Such a criterion may be used alone or a combination of several criteria may be used to selectively add or delete virus pattern data to be loaded on the portable terminal. In addition, the portable terminal according to the present invention and its operation control method are not limited to the configurations and methods of the embodiments described above, but the embodiments may be modified in various ways, Or some of them may be selectively combined.

Meanwhile, the present invention can be embodied as a processor-readable code on a processor-readable recording medium such as a mobile station modem (MSM). The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium readable by the processor include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and also a carrier wave such as transmission over the Internet. In addition, the processor readable recording medium may be distributed over networked computer systems so that code readable by the processor in a distributed manner can be stored and executed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
