The control unit 180 may predict a time required for the data communication when the data communication starts or before the data communication starts.

For example, suppose that the activated application receives traffic information and map information via the Internet 30 and provides route guidance.

When the user inputs a destination and commands route guidance from the current location to the destination, the controller 180 can estimate the time required to reach the route and / or the amount of data traffic required until the route reaches the destination .

The control unit 180 can obtain an expected time required for the data communication based on the route arrival time and / or the data communication amount.

If the predetermined criterion includes the "expected data communication time" as a result of the determination in step S400, the control unit 180 determines that the expected data communication expected time after the application is activated is a preset reference value If it is determined in step S410 that the estimated data communication time exceeds the preset reference value, step S120 is performed.

According to the fourth embodiment of the present invention, when an application set to use the mobile communication network 20 as a private network is activated, the expected time required for data communication through the activated application is estimated in advance, The wireless Internet module 113 is inactivated, so that unnecessary power consumption through the wireless Internet module 113 can be shut down.

9 is a flowchart of a data communication management method of a mobile terminal according to a fifth embodiment of the present invention. 10 is a view for explaining a fifth embodiment of the present invention.

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

Referring to FIG. 9, the controller 180 determines whether the usage criterion for the activated application is included in the predetermined criterion (S500).

The controller 180 may analyze a usage pattern of a user's specific application and store the analyzed usage pattern in the memory 160. [

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

If the predetermined usage criterion includes the "usage pattern" as a result of the determination in step S500, the controller 180 determines whether the average usage time stored in the activated application after the application is activated is greater than a reference value (S510). If the average usage time exceeds the reference value, the process proceeds to step S520.

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

10, the average usage time of the first application (the "first App"), the second application (the "second App") and the fourth application (the "fourth App" So that when they are activated, the wireless Internet module 113 is inactivated.

10, since the average usage time of the third application (the "third App") and the fifth application (the "fifth App") does not exceed the reference value "T2" The wireless Internet module 113 can be kept active 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, based on usage patterns such as an average usage time for the activated application, The unnecessary power wastage through the wireless Internet module 113 can be essentially blocked.

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

Referring to FIG. 11, the controller 180 determines whether the communication status of the portable Internet network 10 is included in the predetermined criteria (S600).

If the predetermined criterion includes the "communication state ", the controller 180 determines whether the communication state of the portable Internet network 10 is defective (S610) If it is determined in step S610 that the communication state of the portable Internet network 10 is bad, step S 120 is performed.

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

In addition, for example, when the error of system information and various information received from the portable Internet network 10 increases, the controller 180 deteriorates the communication environment with the portable Internet network 10, It can be judged to be applicable.

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

The SIB shown in FIG. 12 includes information (Wibro Indicator) 40 indicating whether or not a communication area with the portable Internet network 10 is available.

The SIB shown in FIG. 12 is merely an example, and may be changed to another format when the communication protocol of the mobile communication network 20 conforms to a communication protocol other than WCDMA. The structure and terminology of the SIB shown in FIG. 12 and the number of bits of each information included in the SIB may be changed according to the policy of the provider or other reasons.

The control unit 180 may determine that the communication environment with the portable Internet network 10 has deteriorated when reception of the SIB itself is unstable or an error occurs in the Wibro Indicator 40. [

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

Particularly, 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, Consumption may increase. According to the sixth embodiment of the present invention, in such a case, power consumption of the wireless Internet module 113 is turned off, thereby preventing such power consumption.

13 is a flowchart illustrating an example of an activation process of the wireless Internet module 113 according to an embodiment of the present invention. Referring to FIG. 13, an exemplary detailed process of step S150 shown in FIG. 3 will be described in detail.

Referring to FIG. 13, the controller 180 starts an application using the WCDMA network as a private network (S700).

In step S710, the controller 180 stops the scanning operation on the Wibro network and turns off the wireless Internet module 113 to access the Wibro network [S720]. The state in which steps S710 and S720 are performed will be referred to as "Wibro Stop Mode ".

The control unit 180 determines whether the "Wibro Stop Mode" is released (S730). The step S730 may include at least one of the steps S130 and S140 of FIG.

The controller 180 turns on the wireless Internet module 113 when the Wibro Stop Mode is released as a result of the determination in step S730, And starts a scan operation on the portable Internet network 10 (S750).

If the 'Wibro Stop Mode' is not released as a result of the determination in step S730, the controller 180 may maintain the 'Wibro Stop Mode' (S760).
