Referring to FIG. 3, step S110 in which user information is transmitted to a server or a wireless charging pad and step S120 in which advertisement content related to user information is received from a server or a wireless charging pad is performed.

In the embodiments of the present invention, the visual information may be displayed in the form of a text message or a graphic message in an area where the user interface is displayed in the display unit 251. [ In addition, a pop-up window including visual information may be displayed on the display unit 251. [

The mobile terminal 100 can distinguish between a commercial mode and a home mode for receiving advertisement contents by recognizing the ID of the wireless charging pad. Hereinafter, when the wireless charging pad is a commercial pad, the embodiments of the present invention can be applied.

The wireless recharging pad can detect the mobile terminal 100 first. The wireless recharging pad may perform the analog zipping step and the digital zipping step. In more detail, the current value flowing in the coil of the wireless charging pad changes in the analog charging step, so that the wireless charging pad can detect that the mobile terminal 100 is present on the wireless charging pad. The wireless charging pad may then transmit a minimum amount of power to the mobile terminal 100 to initiate communication with the mobile terminal 100 in the digital phase. As the mobile terminal 100 receives power from the wireless charging pad, it can only sense the wireless charging pad. At this time, the wireless charging pad requests user information to the mobile terminal 100, and the mobile terminal 100 can transmit user information to the wireless charging pad.

On the other hand, the mobile terminal 100 may first sense the wireless charging pad. The mobile terminal 100 can sense the wireless charging pad by receiving the ID of the wireless charging pad through wireless communication. At this time, the mobile terminal 100 can directly transmit the user information to the wireless charging pad.

The wireless communication unit 110 may transmit user information to a server or a wireless charging pad. Specifically, the wireless communication unit 110 transmits the ID of the mobile terminal 100 to the server or wireless charging pad 100 using a reserved packet of an identification & configuration packet conforming to the Wireless Power Consortium (WPC) Lt; / RTI >

Meanwhile, the wireless communication unit 110 may transmit at least one of the user's age, sex, occupation, address, and interest information to the server or the wireless charging pad in addition to the ID of the mobile terminal 100 as user information.

At this time, the wireless communication unit 110 may perform wireless communication with the wireless charging pad using at least one of Near Field Communication (NFC), Bluetooth communication, infrared communication, and ZigBee communication. In addition, the wireless communication unit 110 may perform wireless communication with the server using at least one of a Wi-Fi (Wi-Fi), a 3G network, and a 4G network.

Thereafter, the step S130 in which the advertisement contents are displayed on the display unit 151 proceeds.

The content provider can select the content related to the user information by using the user information. At this time, as described above, the user information includes the ID of the mobile terminal 100, and may include at least one of the user's age, sex, occupation, address, and interest information in addition to the ID.

The mobile terminal 100 may receive the advertisement content from the content provider. Specifically, mobile terminal 100 may download ad content from a content provider via a server or wireless charging pad and store it in memory 160 (see FIG. 1). In addition, the mobile terminal 100 may receive an address of a website from which the advertisement contents can be viewed. Meanwhile, the downloaded advertisement contents may take the form of a DRM (Digital Rights Management) file and may be managed by a content provider even after being stored in the memory 160 of the mobile terminal 100.

The advertisement contents may be directly displayed on the display unit 151 or may be displayed on the display unit 151 by the user's selection after being stored in the memory 160. [

Next, step S 140 is performed in which history information indicating the advertisement content is managed on the display unit 151.

Specifically, the control unit 180 may manage the history information including the display time, the displayed time, or the displayed number of the advertisement contents on the display unit 151. [ Here, wireless charging may be accepted or rejected depending on whether the history information satisfies the set power receiving condition. To this end, the history information may be transmitted to the server or the wireless charging pad through the wireless communication unit 110. [

Specifically, in order for the power receiving condition information to be set, the mobile terminal 100 can receive the service guide information from the server or the wireless charging pad. The control unit 180 can display the received service guide information on the display unit 151 and can set the power receiving condition information based on the user's selection of the displayed service guide information.

The service guide information may include at least one of an amount of power to be wirelessly received from the wireless charging pad, a display time of the advertisement content based on the power reception time, a display frequency of the advertisement content, and a display time of the advertisement content.

Then, based on the history information, the power receiving unit 191 is controlled to receive power wirelessly from the wireless charging pad (S150).

The power receiving unit 191 is configured to receive power (radio power) transmitted wirelessly from the wireless charging pad. At this time, the wireless power may be transmitted using a wireless power transmission scheme such as an inductive coupling scheme, a resonant coupling scheme, or a combination scheme thereof.

The power receiving unit 191 may include components required for receiving wireless power according to the above-described wireless power transmission scheme. For example, the power receiving unit 191 may include a coil for receiving radio power in the form of a magnetic field or an electromagnetic field having oscillating characteristics.

Specifically, the power receiving unit 191 may include a secondary coil that induces a current by a changing magnetic field as a component according to an inductive coupling scheme. The power receiving unit 191 may include a coil and a resonance circuit that generate a resonance phenomenon by an electromagnetic field having a specific resonance frequency.

The power receiving unit 191 can charge the battery using power supplied or transmitted from the wireless charging pad. At this time, the power receiving unit 191 may control a charging voltage, a charging current, a charging speed, and the like.

The control unit 180 can determine whether to receive power from the wireless charging pad using the history information and the power receiving condition information displayed in the advertisement content. That is, when the history information satisfies the power receiving condition, the control unit 180 can control the power receiving unit 191 to wirelessly receive power from the wireless charging pad.

On the other hand, when the history information does not satisfy the power receiving condition, the controller 180 may display a popup window on the display unit 151 indicating that the power receiving condition is not satisfied. At this time, based on the history information, the control unit 180 may adjust the power amount of the power that the power receiving unit 191 wirelessly receives from the wireless charging pad.

Meanwhile, the controller 180 may transmit the history information and the power receiving condition information to the server or the wireless charging pad. At this time, it is determined whether the history information satisfies the power receiving condition in the server or the wireless charging pad, The mobile terminal 100 may receive either a wireless charging authorization message and a wireless charging rejection message from the server or wireless charging pad.

Specifically, only one of the power amount information 259a and the display time information 259b of the advertisement content can be displayed on the display unit 251. [ In addition, the display time point of the power amount information 259a and the display time point information 259b of the advertisement content may be different. For example, either the power amount information 259a or the display time point information 259b of the advertisement contents may be displayed first on the display unit 251 and the other may be displayed on the display unit 251 later.

The time at which information and information displayed on the display unit 251 are displayed may be set according to a preset content in the mobile terminal 200 or may be set by a user.

The control unit 180 may manage the history information including the display time, the displayed time, or the displayed number of the advertisement contents on the display unit 151. [

At this time, if the history information satisfies the power reception condition, a step S430 of displaying a wireless charging approval message on the display unit 151 is performed.

In this case, step S440 may be performed in which the mobile terminal 100 requests power transmission to the network communication device. The mobile terminal 100 may request the power transmission to the network communication device through the wireless charging pad or request the power transmission directly to the network communication device. Thereafter, the wireless charging pad transmits power wirelessly to the mobile terminal 100 (S450).

On the other hand, if the history information does not satisfy the power reception condition, a step S420 of displaying a wireless charging rejection message on the display unit 151 proceeds. At this time, based on the history information, the amount of power to be wirelessly received from the wireless charging pad can be adjusted. Accordingly, the mobile terminal 100 can receive power from the wireless charging pad by a controlled amount of power.

To this end, the mobile terminal 100 may control the frequency of the power receiving unit 191 (see FIG. 1) to limit the amount of power of the power wirelessly received from the wireless charging pad.

Specifically, the wireless charging pad or the network communication device can determine whether the history information satisfies the power receiving condition using the received history information and the received power receiving condition information.

At this time, when the history information satisfies the power receiving condition, the wireless charging pad or the network communication device transmits the wireless charging approval message to the mobile terminal 100 and the step of transmitting power wirelessly (S540). Meanwhile, the wireless charging pad or the network communication device may transmit power to the mobile terminal 100 only when the approval message is received from the mobile terminal 100 after transmitting the wireless charging approval message.

On the other hand, if the history information does not satisfy the power receiving condition, the wireless charging pad or the network communication device transmits a wireless charging reject message to the mobile terminal 100 (S530). At this time, the wireless charging pad or the network communication device can adjust the amount of power to be wirelessly received by the mobile terminal 100 based on the history information. Accordingly, the wireless charging pad can transmit power to the mobile terminal 100 by the adjusted power amount.
