Hereinafter, a method of managing data communication of a mobile terminal according to a fifth embodiment of the present invention and an operation of the mobile terminal 100 for implementing the same will be described in detail with reference to the accompanying drawings.

Referring to FIG. 9, the controller 180 determines whether a “use pattern” for the activated application is included in the predetermined criterion [S500].

The controller 180 may analyze a usage pattern of a specific application of the user and store it in the memory 160.

For example, a usage pattern for the specific application may be analyzed and stored, such as the number of times of use of the specific application, the frequency of use for a certain period of time, and the average time of use for a single use.

The controller 180 determines that the average usage time stored for the activated application after the application is activated when the "use pattern" is included in the predetermined criterion as a result of the determination in step S500. If it is determined that the time exceeds the [S510], if the average time of use exceeds the reference value to perform the step S120 [S520].

10 is a diagram illustrating an example of an average usage time analyzed cumulatively for various applications. In addition, "T2" illustrated in FIG. 10 is a reference value set for deactivation of the wireless Internet module 113.

Referring to FIG. 10, the average usage time of the first application ("first app"), the second application ("second app"), and the fourth application ("fourth app") is "T2" which is the reference value. Since the wireless Internet module 113 is deactivated when they are activated.

Also, referring to FIG. 10, since the average usage time of the third application ("third App") and the fifth application ("fifth App") does not exceed the reference value "T2", when they are activated, The wireless internet module 113 may remain activated without being deactivated.

According to the fifth embodiment of the present invention, when an application configured to use the mobile communication network 20 as a dedicated network is activated, the wireless Internet module 113 is based on a usage pattern such as an average usage time for the activated application. By being deactivated, unnecessary waste of power through the wireless internet module 113 may be blocked at source.

11 is a flowchart of a data communication management method of a mobile terminal according to a sixth embodiment of the present invention. 12 shows an example of system information received from a WCDMA network.

The data communication management method of the mobile terminal according to the sixth embodiment of the present invention may be implemented in the system environment and the mobile terminal 100 described with reference to FIGS. 1 and 2. Hereinafter, a method of managing data communication of a mobile terminal according to a sixth embodiment of the present invention and an operation of the mobile terminal 100 for implementing the same will be described in detail with reference to the accompanying drawings.

Referring to FIG. 11, the controller 180 determines whether the "communication state" of the portable Internet network 10 is included in the predetermined criterion [S600].

The controller 180 determines whether the communication state of the portable Internet network 10 corresponds to a failure when the "communication state" is included in the predetermined criterion as a result of the determination in step S600 [S610]. If the communication state of the portable Internet network 10 corresponds to a result of the determination of step S610, the step S120 is performed [S620].

For example, when the received signal strength indication (RSSI) / carrier to interface ratio (CINR) received from the portable Internet network 10 is lower than a predetermined reference value, the controller 180 may execute the portable Internet network 10. It can be determined that the communication environment with the network corresponds to the failure.

Also, for example, when the error of the system information and various information received from the portable Internet network 10 increases, the controller 180 may deteriorate the communication environment with the portable Internet network 10 and cause a defect. It can be judged as applicable.

12 illustrates an example of a system information block (SIB) that is system information received from the mobile communication network 20 through the mobile communication module 112.

The SIB illustrated in FIG. 12 includes information (Wibro Indicator) 40 indicating whether the area is available for communication with the portable Internet network 10.

The SIB illustrated in FIG. 12 is merely an example. When the communication protocol of the mobile communication network 20 conforms to a communication protocol other than WCDMA, the SIB may be changed to another format. In addition, the structure and terminology of the SIB illustrated in FIG. 12, 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.

When the reception itself of the SIB is unstable or an error occurs in the Wibro Indicator 40, the controller 180 may determine that the communication environment with the portable Internet network 10 is deteriorated.

According to the sixth embodiment of the present invention, when an application configured to use the mobile communication network 20 as a dedicated network is activated, the communication environment with the mobile Internet network 10 corresponds to a weak electric field. If the communication environment with (10) is bad, the wireless Internet module 113 is deactivated, unnecessary waste of power through the wireless Internet module 113 can be blocked.

In particular, when the electric field strength of the portable internet network 10 is a weak electric field, the mobile terminal 100 continuously scans the portable internet network 10 through the wireless internet module 113, thereby providing power. Consumption may increase. According to the sixth embodiment of the present invention, in this case, the power of the wireless Internet module 113 is turned off, thereby preventing such power consumption.
