The control unit 180 can re-receive the system information from the mobile communication network 20 (S130). In this way, the system information can be periodically or intermittently received from the mobile communication network 20. The transmission and reception of the system information may be in accordance with the communication protocol for the mobile communication network 20. [

The controller 180 determines whether the re-received system information is good (S140). If the re-received system information is good, the controller 180 activates the wireless Internet module 113 (S150).

The control unit 180 refers to a database for managing a communication defective area of at least one of the portable Internet network 10 and the mobile communication network 20 and determines whether the acquired current location is an area registered in the database (S310).

The database may be stored in the memory 160 or may be stored in a specific external server. The database may also be updated periodically.

If the database is stored in the external server, the controller 180 transmits information on the obtained current area to the external server, and transmits a communication defective area corresponding to the obtained current area information to the database It can be queried whether it exists.

The external server may transmit a response to the inquiry to the mobile terminal 100.

The control unit 180 may receive a response to the inquiry, and may determine, based on the response, whether the acquired current location is an area registered in the database.

In addition, the database can store and manage not only communication defective areas of the mobile communication network 20 but also communication defective areas of the portable Internet network 10. [

The database also stores other information such as a communication defective area related to at least one of the mobile communication network 20 and the portable internet network 10 and an electric field intensity such as the intensity of a received signal in the defective area .

If the obtained current location is the area registered in the database as a result of the determination in step S310, the controller 180 updates the database [S320], provides the related information to the user [S330] And deactivates the wireless Internet module 113 for connecting to the portable Internet network 10 [S340].

In step S320, information other than the acquired current position may be updated with respect to the database.

The related information includes at least one of a communication state of the mobile communication network 20, a communication defective area of the mobile communication network 20, and inactivation of the wireless Internet module 113.

For example, in step S330, the control unit 180 determines that the mobile terminal enters the weak electric field area of the mobile communication network 20 before or after the wireless Internet module 113 is deactivated, The user can be notified that the power of the wireless Internet module 113 will be turned off.

The control unit 180 may display the related information on the display unit 151 or output the audio information through the audio output module 152.

Also, the controller 180 may provide a user interface for inquiring about power off of the wireless Internet module 113 at the same time as notifying the related information.

The user can confirm the power off of the wireless Internet module 113 via the power off user interface or issue a command to the controller 180 to keep the power of the wireless Internet module 113 on .

The third embodiment of the present invention can reactivate the deactivated wireless Internet module 113 in the manner described in the first and second embodiments of the present invention.

For example, when activating the wireless Internet module 113 according to the first embodiment of the present invention, the control unit 180 may receive the system information (for example, FIG. 4B) received from the mobile communication network 20 The wireless Internet module 113 can be activated based on the SIB shown in FIG.

For example, when activating the wireless Internet module 113 according to the second embodiment of the present invention, the controller 180 may control the wireless Internet module 113 through a user interface The wireless Internet module 113 can be activated based on the received command signal.

If the acquired current location is not the area registered in the database as a result of the determination in step S310, the controller 180 determines whether the communication state with the mobile communication network 20 is bad, If the communication state with the communication network 20 is bad, the obtained current position can be registered in the database. The controller 180 provides the related information to the user at step S330 and deactivates the wireless Internet module 113 to access the portable Internet network at step S340.

If the acquired current location is not the area registered in the database as a result of the determination in step S310, the controller 180 determines whether the communication state with the portable Internet network 10 is bad (step < RTI ID = 0.0 > S350].

For example, the controller 180 may control the RSSI (Carrier to Interface Ratio) and the RSSI (Received Signal Strength Indication) for the portable Internet network 10, as described in the first embodiment of the present invention, It is possible to determine the state of communication with the portable Internet network 10 based on the received information.

If it is determined that the communication state with the portable Internet network 10 is bad, the controller 180 registers the obtained current location in the database (S360).

Here, the control unit 180 may register the obtained current position in the database as the communication defective area of the portable Internet network 10 and / or the mobile communication network 20. [

Meanwhile, the control unit 180 may transmit part or all of the database to an external terminal or an external server according to a user's command or a preset reference.
