[ However, the wireless communication unit 110 may be in an operating state even if there is no user input.

The wireless communication unit 110 receives the wireless communication signal from the wireless LAN access point (S410). Then, the control unit 180 extracts the service set identifier from the wireless communication signal (S420).

When the extraction of the service set identifier is completed, the controller 180 stops the operation of the wireless communication unit 110 (S520). The controller 180 stops the operation of the wireless communication unit 110, so that the power consumed by the wireless communication unit 110 is reduced.

When the operation of the wireless communication unit 110 is stopped, the control unit 180 enters the step of acquiring information related to the service set identifier (S430).

Next, with reference to FIG. 6, the mobile terminal 100 displaying the service set identifier related information will be described.

FIG. 6 is an exemplary view in which the mobile terminal 100 according to an embodiment of the present invention acquires and displays information related to a service set identifier. 6A, the control unit 180 may operate the wireless communication unit 110 through an input for releasing the user's lock screen 600 received through the display unit 151.

6 (b), the control unit 180 controls the display unit 151 so that the service set of at least one wireless LAN access point 310, 312, and 314, which transmits the wireless communication signal currently received, Identifiers 610 (a), 610 (b), 610 (c) are displayed. At this time, the controller 180 controls the indicators 612 (a), 612 (b), 610 (b) and 610 (b) to indicate the signal strengths of the respective wireless communication signals to correspond to the respective service set identifiers 610 b), 612 (c)) can be displayed together.

Then, when an input for selecting one of the service set identifiers 610 (a) is received by the user, the control unit 180 receives the service set identifier 610 (a) and the service set identifier 610 Related information can be displayed.

For example, when an input for selecting " GS25_gasan " is received, the control unit 180 transmits the coupon information 620 (a), membership information 620 (b), or event information 620 (c) And displays it. At this time, " GS25 " is information included in the service identifier 610 (a), and may be mutual information of stores where the wireless LAN access point 310 is installed.

That is, the control unit 180 can acquire the information 622 (a), 622 (b), 622 (c) related to the shop and display it on the display unit 151. The control unit 180 can obtain information 622 (a), 622 (b), and 622 (c) related to the store from the memory unit. In one example, the control unit 180 may display the store-related information 622 (a), 622 (b), 622 (c) by searching for and executing an application program associated with the store.

As another example, if the application program is not installed in the memory unit, the control unit 180 may display a web page to the user that can receive the application program.

As another example, the control unit 180 can search for coupon information or event information related to a shop from an external server through the wireless communication unit 110 and display the coupon information or the event information.

When the user selects the object 622 (b) for displaying the membership information in the barcode form, the controller 180 displays the membership information 630 related to the shop in a barcode format as shown in FIG. 6 (d) Can be displayed.

Accordingly, the mobile terminal 100 according to an embodiment of the present invention uses the information contained in the service set identifiers 610 (a), 610 (b), 610 (c) ), 622 (b), 622 (c)). When the mobile terminal 100 receives the wireless communication signal having the service set identifier 610 (a), 610 (b), 610 (c) including the store mutual name, the coupon information 622 ), Membership information 622 (b), or event information 622 (c).

On the other hand, when the wireless communication signal is received and the service set identifier related information 630 is displayed, the controller 180 can associate the wireless communication signal with the displayed service set identifier related information 630, .

7 is a flowchart illustrating a method of displaying service set identifier related information of the mobile terminal 100 according to another embodiment of the present invention. As shown in the figure, the control unit 180 stores the wireless communication signal and the information 630 related to the indicated service set identifier in the memory unit (S700).

For example, after the wireless communication unit 110 receives the wireless communication signal from the wireless communication access point 310 located in the shop, if the barcode-type membership information 630 related to the shop is displayed by the user, May associate and store the service set identifier 610 (a) of the wireless communication signal with the bar code type membership information 630. [

When the wireless communication signal is re-received (S710), the controller 180 re-displays the service set identifier related information 630 stored in association with the re-received wireless communication signal on the display unit 151 (S720) .

Accordingly, the mobile terminal 100 according to another embodiment of the present invention can easily provide information 630 related to the service set identifier to the user.

In addition, the control unit 180 can display at least one service set identifier related information on the display unit 151, and will be described with reference to FIG.

8 is an exemplary diagram showing service set identifier related information 820 and 822 of the mobile terminal 100 according to another embodiment of the present invention. As shown in FIG. 8 (a), when there is information on the service set identifier previously displayed in association with the service set identifier of the wireless communication signal received by the wireless communication unit 110, the control unit 180 displays a notification window 810) can be displayed on the display unit 151.

Then, the service set identifier 812 of the received wireless communication signal is displayed in the notification window 810, and when the user selects the object 814 displaying the service set identifier related information displayed previously, As indicated, the control unit 180 displays at least one service set identifier related information 820, 822.

For example, when at least one service set identifier related information 820 and 822 is barcode information, the control unit 180 may display at least one barcode information on the display unit 151. [

In addition, when at least one service set identifier related information 820, 822 is displayed in a predetermined order by the user, the control unit 180 arranges and displays the service set identifier related information 820, 822 in a predetermined order .

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . Also, the computer may include a control unit of the terminal.

Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
