In addition, the structure and terminology of the SIB illustrated in FIG. 4, and the number of bits of each information included in the SIB may be changed according to a policy of an operator or other reasons.

The controller 180 determines whether the received system information corresponds to a defect [S110].

The controller 180 may determine whether the received system information is defective based on a first predetermined criterion.

The first predetermined criterion includes a case where a communication environment with the mobile communication network 20 is deteriorated, and a case where an error is detected in the received system information.

For example, when the strength of the signal received from the mobile communication network 20 is less than or equal to a reference value, the controller 180 determines that the communication environment with the mobile communication network 20 is deteriorated, and the received system information It can be determined that the failure corresponds.

In addition, for example, when an error such as a CRC error occurs in the Wibro Indicator 40 included in the received SIB information, the controller 180 determines that an error is detected in the received system information. It can be determined that the received system information corresponds to the failure.

The controller 180 deactivates the wireless internet module 113 for accessing the portable internet network 10 when the received system information corresponds to a defect as a result of the determination in step S110 [S120].

Herein, the controller 180 may turn off the power of the wireless Internet module 113 for accessing the portable Internet network 10.

The controller 180 may deactivate the wireless internet module 113 and then control the indicator to indicate the deactivated state of the wireless internet module 113.

The controller 180 can re-receive the system information from the mobile communication network 20 [S130]. As such, the system information may be periodically or intermittently received from the mobile communication network 20. The transmission and reception of the system information may be in accordance with a communication protocol relating to the mobile communication network 20.

The controller 180 determines whether the re-received system information is good [S140], and activates the wireless Internet module 113 when the re-received system information is good [S150].

The controller 180 may store or register a communication state of at least one of the mobile communication network 20 and the portable Internet network 10 regarding the current region of the mobile terminal 100 in a communication state database. [S160].

The current area of the mobile terminal 100 may be obtained through information received from the mobile communication network 20 or may be obtained through the location information module 115.

The communication state database may be stored in the memory 160 or managed by a separate server existing outside the mobile terminal 100.

When the communication state database is stored in the separate server, the controller 180 may transmit a communication state of the current region to the separate server through the wireless communication unit 110.

The controller 180 may perform step S160 according to a predetermined condition.
