The proximity sensor may be configured to output different proximity signals according to a distance between the proximity-touched pointer and the touch screen (hereinafter referred to as "proximity depth").

A distance at which the proximity signal is output when the pointer approaches the touch screen is referred to as a detection distance. In short, by using a plurality of proximity sensors having different detection distances, the proximity signals output from the proximity sensors are compared, .

In FIG. 3, for example, a cross section of a touch screen on which three proximity sensors capable of sensing three proximity depths is disposed is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d0), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d1, it is recognized as a proximity touch of the first proximity depth.

If the pointer is located on the touch screen at a distance d1 or less and less than the distance d2, the pointer is recognized as a proximity touch of the second proximity depth. When the pointer is spaced apart from the d2 distance by more than d3 distance on the touch screen, it is recognized as a proximity touch of a third proximity depth. If the pointer is located at a distance d3 or more on the touch screen, it is recognized that the proximity touch is released.

Accordingly, the controller 180 can recognize the proximity touch as various input signals according to the proximity and proximity positions of the pointer to the touch screen, and perform various operation controls according to the various input signals.

The backhaul lines may be configured according to E1 / T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL known to those skilled in the art. It will be apparent to those skilled in the art that the system may include more than one base station controller 275.

Each of the base stations 270 may include one or more sectors and each sector may include an omnidirectional antenna or a specific radially tuned antenna from the base station 270 . Alternatively, each sector may include two antennas for diversity reception. Each base station 270 is configured to accommodate a plurality of frequency assignments, and the frequency assignments may have a specific spectrum (e.g., 1.25 MHz, 5 MHz).

The intersection of sectors and frequency assignments may be referred to as a CDMA channel.

The base stations 27 may also be referred to as base station transceiver subsystems (BTSs). In some instances, the term "base station" may be used to refer collectively to a base station controller 275 and one or more base stations 270. The base stations may also be denoted "cell sites ". Alternatively, individual sectors of a given base station 270 may be referred to as cell sites.

The terrestrial DMB transmitter 295 can broadcast to the mobile terminals 100 operating in the system. The broadcast receiving module 111 of the mobile terminal 100 is generally configured to receive broadcast signals transmitted by the DMB transmitter 295. This may be similarly applied to other types of broadcast and multicast signaling as described above.

FIG. 4 shows various GPS (Global Positioning System) satellites 300. These satellites 300 may track the location of some or all of the mobile terminals 100. Although two satellites are shown, it is apparent to those skilled in the art that the location information can be obtained from more or fewer satellites. Other types of location tracking techniques (e.g., location tracking techniques that may be used in place of or in addition to GPS technology) may be used. If desired, some or all of the GPS satellites 300 may be configured to separately or additionally support satellite DMB transmission.

During operation of the wireless communication system, the base stations 270 receive reverse link signals from a plurality of mobile terminals 100. The mobile terminals 100 may be busy, are sending messages, and are performing other communications. Each reverse link signal received by the base station is processed at the base station. The processed data is transmitted to the connected base station controller 275. The base station controller 275 provides call resource allocation and provides mobility management functionality including orchestration of soft handoffs between the base stations 270. [ ). The base station controllers 275 also transmit the received data to the mobile switching centers (MSCs) 280.

5 is a flowchart of a mobile terminal according to an embodiment of the present invention.

As shown in the drawing, the controller 180 of the mobile terminal 100 according to an embodiment of the present invention may allow the step (S10) of identifying a point at which wireless charging is possible.

Wireless charging may refer to a method of charging power to the battery 195 without a physical contact.

The battery 195 may be built in the mobile terminal 100 to supply power to the mobile terminal 100 while carrying the mobile terminal 100. The battery 195 may be charged by receiving power through the wired charging module 191 and / or the wireless charging module 193. The state of charge of the battery 195 may be detected through the battery level detection module 142 of the sensing unit 140.

The remaining battery detection module 142 may detect the amount of power charged in the battery 195. That is, when the maximum amount of power that can be charged in the battery 195 is 1, it means that the amount of power currently charged in the battery 195 can be detected. The battery level detection module 142 may measure the current power amount substantially in real time or at regular time intervals.

The wired charging module 191 may be a device used to charge the battery 195 by receiving power through a wired wire. For example, it may be a device that receives power from an outlet and supplies power to the battery 195.

The wireless charging module 193 may be a device used to charge the battery 195 by receiving power via wireless. When the battery 195 is in a charged state, the wireless charging module 193 may be different from the wired charging module 191 in that a wireless power line is formed between the outlet and the mobile terminal 100. The charging of the battery 195 through the wireless charging module 193 may be performed by a magnetic induction method, a magnetic resonance method, or the like.

Wireless charging using a magnetic induction method may refer to a method of transmitting power wirelessly using an electromagnetic induction method. The electromagnetic induction method may be a method of charging through a magnetic field induced between a primary coil transmitting electricity and a secondary coil receiving electricity.

The wireless charging using a magnetic resonant method may be a wireless charging method using a principle that causes the transmitting side and the receiving side to resonate at the same frequency. Magnetic resonance may be capable of wireless charging at a relatively long distance. Further, the transmitting side and the receiving side may be in a one-to-many relationship. That is, it means that a plurality of mobile terminals 100 can be charged at the same time.

Checking the current position (S20) may proceed.

The current location may be the current point of the user who owns the mobile terminal 100. The current position can be calculated based on the signal received from the satellite transmitting the GPS signal. For example, by applying a triangulation technique based on GPS signals received from at least three satellites, it is possible to calculate the point where the mobile terminal 100 is located on the ground surface.

Determining whether to proceed with the wireless charging (S30) may proceed.

Wireless charging may be possible within a certain radius from the device performing the wireless charging function. This may be similar to wi-fi that can be used only within a certain radius from the access point (AP). In addition, in the case of wireless charging using a magnetic induction method, a point where wireless charging is possible may mean a point where an apparatus for providing a magnetic induction method is provided.

In order to proceed with the wireless charging, it must be within a certain range at the point of providing wireless charging. In addition, the wireless charging may be performed when the power charged in the battery 195 is less than or equal to a certain degree. Furthermore, wireless charging can proceed when the user has taken a particular action. As such, wireless charging may proceed when some conditions are satisfied.

When the determination on the progress of the wireless charging is made, step S40 of proceeding with the wireless charging according to the attribute of the wireless charging possible point may proceed.

An attribute of a point at which wireless charging is possible may be whether or not wireless charging is charged at that point. That is, the wireless charging may be paid or free.

If the wireless charging is free, charging through the wireless charging module 193 may proceed without a separate procedure.

If the wireless charging is paid, a series of processes for proceeding with the wireless charging may proceed.

FIG. 6 is a flowchart illustrating a process of wireless charging in FIG. 5.

As shown in the drawing, the controller 180 can proceed to step S41 of determining whether or not it is a paid charging area.

The paid charging area may be an area where charging is made according to the amount and / or time of wireless charging, as described above. Wireless charging in the paying region may be performed only for a certain mobile terminal 100 that has performed the charging operation.

In the case of the paying charging area, the authentication step S42 may proceed.

The authentication may be a procedure for specifying the mobile terminal 100 in order for the charging procedure and the wireless charging to proceed. For example, it may be a procedure for specifying the mobile terminal 100 to perform wireless charging. Authentication will be described in detail in the corresponding part, but may be performed through NFC and / or carrier server.

If authentication is made, step S43 of selecting a charging method may proceed.

The billing method may be whether or not to pay for the wireless charging which is charged. For example, it means whether the payment is to be made through any means, such as NFC, credit card payment means.

When the charging method is selected, step S44 of selecting the charging amount may proceed.

The charging amount may be an amount of power charged in the battery 195.

The filling amount can be expressed and selected in various forms. For example, the filling amount may be expressed in percentile units. That is, when the fully charged state is 100% and the current charge amount is 10%, it may be possible to select to charge up to 70%. In addition, the filling amount may be expressed by time. For example, this means that charging can proceed for the next hour.

If the charging amount is selected, step S45 of proceeding with wireless charging may be performed.

When the wireless charging is performed, the amount of power charged in the battery 195 may be increased.

7 is a diagram showing a wireless charging possible region on a map.

As shown, the mobile terminal 100 may be located at the point P. The location of the mobile terminal 100 may be calculated through the location information module 115.

In the vicinity of the mobile terminal 100, there may be a point where wireless charging is possible. For example, A1 to A4 may be located. Information about A1 to A4 may be obtained through the mobile communication module 112, the wireless internet module 113, the short range communication module 114, and the like.

The information on A1 to A4 includes information on the location of A1 to A4, information on the range of wireless charging available through A1 to A4, information on the wireless charging strength of A1 to A4, and information on A1 to A4 wireless charging efficiency. And the like. In addition, it may further include information on whether the charging at the A1 to A5 wireless charging point.

Knowing the information on the point P, which is the current location of the mobile terminal 100, and the information on the points A1 to A4, which are wireless charging points, the controller 180 can calculate a distance from the wireless charging point.

FIG. 8 is a table dividing the wireless charging area of FIG. 7 into a pay area and a free area.

As shown in the drawing, a wireless charging point may be divided into a pay point and a free point. That is, points A1 and A2 are points where wireless charging is possible for a fee, and points A3 and A4 may be points where wireless charging is free.

Specific information on a point where wireless charging is possible may be obtained from a server or the like. For example, the information may be obtained from a server in real time or may be acquired and retrieved from information stored in the memory 160.

9 is a diagram illustrating an entry process of a wireless charging region.

As shown in the drawing, the mobile terminal 100 according to an embodiment of the present invention may be in a situation of gradually entering an area where wireless charging is possible.

The mobile terminal 100 may be in the first position P1. The first location P1 may be outside of an area where wireless charging is possible. That is, when it is in the first position P1, it means that charging using wireless charging may not proceed. In this state, the controller 180 may perform a control operation to minimize the use of the battery 195 of the mobile terminal 100. For example, this means that the amount of light of the display 151 may be reduced, or the display area of the display 151 may be reduced.

The mobile terminal 100 may be in the second position P2. The second location P2 may also be outside of an area where wireless charging is possible. That is, similarly to the first position P1, the charging using the wireless charging may not be performed in the second position P2. However, unlike the first position P1, the second position P2 may be a point closer to the third position P3, which is an area in which the mobile terminal 100 can be wirelessly charged. In the case of approaching the third position P3, which is an area where wireless charging is possible, the controller 180 may enlarge the light amount, the display area, etc. of the display 151 at the first position P1.

The mobile terminal 100 may be in the third position P3. The third location P3 may be inside of an area where wireless charging is possible. When wireless charging is performed at the third position P3, the controller 180 may maximize the amount of light, the display area, and the like of the display 151.

FIG. 10 is a diagram illustrating an authentication process of the mobile terminal of FIG. 5.

As shown here, the authentication of the mobile terminal 100 may be performed through the NFC device 200 and / or the server (S).

Authentication via the NFC device 200 may be initiated through tagging the mobile terminal 100 to the NFC device 200. When tagging is performed, the short range communication module 114 and the NFC device 200 may exchange data with each other. In this process, authentication for the mobile terminal 100 may be performed.

Authentication via the server S may be performed via the mobile communication module 112 and / or the wireless internet module 113. That is, when the mobile terminal 100 transmits a unique number or the like to the server S, it means that a series of authentication processes can be performed with the server S that has received it.

FIG. 11 is a diagram illustrating a charging method setting of the mobile terminal of FIG. 5.

As shown in the figure, the user of the mobile terminal 100 may select a charging method. That is, when wireless charging is performed in the euro, it means that it is possible to determine how to pay the wireless charging fee that is paid.

The selection of the charging method may be performed in the form of selecting any one of the related contents displayed on the display 151. For example, the display 151 may display a first popup window P1 for selecting a charging method.

In the first pop-up window P1, a menu for selecting one of the charges through viewing of the advertisement, the charges through the purchase of goods, and the charges through direct payment may be displayed. The user can select an appropriate menu from these to allow billing to proceed.
