Hereinafter, the most preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily implement the technical idea of the present invention. .

First, Figure 1 is a block diagram showing a mobile communication system having a virus treatment function according to an embodiment of the present invention, at least one mobile subscriber (MS) (111 ~ 114), at least one base station (121, 122) And a mobile switching center (MSC) 130.

The MSs 111 to 114 have a virus vaccine program for treating viruses therein. Preferably, the MSs 111 to 114 check a virus infection before data transmission.

At least one of the base stations 121 and 122 and the mobile switching center 130 is configured to be associated with a database (DB) 131 and a virus monitoring unit (VMU) 132. The database 131 stores various vaccine programs and is updated and managed by a system administrator. The virus monitoring unit 132 serves to substantially control the virus treatment function and the function of updating the virus vaccine program according to the present invention.

2 and 3 with respect to the operation of the mobile communication system having a virus treatment function as described above are as follows.

First, when the virus monitoring unit 132 finds a virus in the data transmitted from at least one of the MSs 111 to 114 (S202) (S202), the virus monitoring unit 132 analyzes / identifies the identity of the found virus ( S203), the antivirus program corresponding to the corresponding virus information is read from the database (DB) 131 (S204) to perform a treatment process (S205). Thereafter, the data is transmitted to the desired destination, and the MS, which is the source of the data, is notified of the virus infection (S206), so that the MS can treat the virus (S207).

If the notified MSs 111 to 114 are unable to cure the virus with an internally stored vaccine program (S301), a "vaccine request message" is transmitted to the virus monitoring unit 132 (S302). . Thereafter, the virus monitoring unit 132 selects an antivirus program corresponding to the corresponding virus information from the database 131 according to the vaccine request message, and transmits the vaccine program to the MSs 111 to 114, or the MS 111. If the version of the anti-virus program of ˜114) is low (S303). Therefore, the MS will treat the internal virus (S304).

In this case, the vaccine request message is preferably a vaccine field (vaccine field) indicating the vaccine version of the MS, a virus information field (virus information field) indicating the identity, and the band (band) and mode of the MS It includes a capability field indicating the capability (including, but not limited to) (mode) or OS information (information to make the vaccine program compatible with the terminal) and the like. Upon receiving the vaccine request message, the virus monitoring unit 132 selects a vaccine program stored in the database 131 according to the MS capability and virus information, and transmits / updates the MS to the MS.

In addition, if the MS 111-114 detects a virus on its own before transmitting data, but cannot heal the virus, it transmits a "vaccine request message" to the virus monitoring unit 132 to receive the vaccine program in the same manner as above. Get updated.

On the other hand, the update of the virus vaccine program is largely performed in two ways, network-initiated and user-initiated.

4 is a flowchart illustrating a network-driven vaccine program update method.

Network-driven antivirus program updates are performed by service providers, for example, when new versions of antivirus programs are released or when new viruses emerge.

When the vaccine program is updated in the network (S501), the virus monitoring unit (VMU) 132 transmits a "vaccine information request message" to the MSs 111 to 114 (S502), and in response, the MS 111 to 114 may notify the virus monitoring unit 132 of the vaccine program information, virus information and its own capability which are owned through the "vaccine information response message" (S503). . Thereafter, the virus monitoring unit 132 selects a suitable vaccine program from the database (DB) 131 according to the capability and virus information of the MSs 111 to 114 and transmits it to the MSs 111 to 114, The vaccine program is updated (S504).

5 is an operation flowchart showing a user-driven vaccine program updating method.

When the user requests an antivirus program update (S601), the MS 111-114 may virus a "vaccine update request message" including information about its antivirus program and its own capabilities. The transmission is sent to the monitoring unit 132 (S602). In response, the virus monitoring unit 132 updates the vaccine program by selecting a vaccine program suitable for the capacities of the MSs 111 to 114 from the database 131 and transmitting the vaccine program to the MSs 111 to 114. It is made (S603).

The above-described vaccine program update is performed through an over-the-air (OTA) scheme.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited to the drawings shown.

The present invention configures a database and a virus monitoring unit (VMU) for storing various antivirus programs to be linked with the system, thereby providing a vaccine program suitable for viruses as well as checking whether the data is infected with the virus during data transmission. There is an advantage to protect the system equipment and mobile communication terminal from the virus by treating the virus.

In addition, the virus vaccine program can be updated through the OTA method, which is very convenient for the user, and the vaccine program can be updated in a timely manner whenever a new version of the vaccine program is released, so both the system and the mobile terminal are protected from viruses. can do.
