When the user selects the icon 50, the controller 180 transmits the WLAN ad hoc connection information corresponding to the icon 50 to the other terminal 200 or transmits the WLAN ad hoc connection information And may provide a user interface for selecting the other terminal 200.

The control unit 180 may transmit the ad-hoc connection information automatically generated in step S110 to the other terminal 200 (S120).

The step S120 may be performed according to various conditions.

For example, the steps S110 and S120 may be performed according to the user's command received in step S100.

Also, for example, if the transmission order for the ad hoc connection information automatically generated in step S110 is received from the user, step S120 may be performed.

As described above, the control unit 180 can transmit the generated ad-hoc connection information to the other terminal 200 by various communication methods.

For example, the ad-hoc connection information may be transmitted to the other terminal 200 (i. E., 200) by a short-range communication method including at least one of Bluetooth, IrDA, UWB and Near Field Communication ). ≪ / RTI >

When the ad hoc connection information is transmitted by a specific local area communication method, the ad hoc connection information may be transmitted to the other terminal 200 according to a communication protocol defined by the specific local area communication method. Here, depending on the communication protocol defined by the specific local area communication method, a search or a scan may be required between the mobile terminal 100 and the other terminal 200.

Also, for example, the ad hoc connection information can be transmitted to the other terminal 200 by a message. The message may include at least one of a Short Message Service (SMS) message, a Multimedia Messaging System (MMS) message, and an E-mail message.

An example of the form of the message is as follows.

The message may include an identifier (for example, 4 bytes) indicating that the current message includes WLAN ad hoc connection information other than a general message, as header information.

The message may include an SSID (e.g., 32 bytes or less) that is the name of the currently configured IBSS, IP information, security information, and the like.

On the other hand, the message may be automatically changed in accordance with its capacity. For example, the type of the message may be determined automatically by SMS or MMS depending on the capacity.

It is clear that the communication scheme for the ad-hoc connection information transmitted and received between the mobile terminal 100 and the other terminal 200 is not limited.

FIG. 9 shows a screen in which a menu for transmitting the ad hoc connection information by a message is selected.

The control unit 180 may transmit the ad hoc connection information previously generated by the method described in this document to the terminal 200 in the form of a message.

9, when the user selects the second menu 21 shown in FIG. 9, the controller 180 generates the ad-hoc connection information according to the above-described method, and transmits the generated ad hoc connection information to the terminal 200 May be transmitted.

Fig. 10 shows another example of a user interface for the ad-hoc connection.

For example, when the user selects "SMS Easy Pairing" shown in FIG. 10, the controller 180 can transmit the ad hoc connection information to the other terminal 200 in various ways as described above.

For example, when the user selects the "stored network" shown in FIG. 10, the controller 180 can transmit the generated ad-hoc connection information to the other terminal 200.

FIG. 11 shows an example of a screen for receiving a telephone number corresponding to the other terminal 200 when the ad-hoc connection information is transmitted by a message by SMS or MMS.

11, when the user inputs a telephone number corresponding to at least one other terminal, and then selects a transmission button, the control unit 180 transmits the generated ad-hoc connection information to the input telephone To at least one other terminal corresponding to the number.

Meanwhile, the controller 180 may configure the ad-hoc connection information in various forms and transmit the ad-hoc connection information to the other terminal 200.

The ad-hoc connection information may include the first setting information for the mobile terminal 100 and the second setting information for the other terminal 200, as described above. The first setting information and the second setting information may be partly the same and the remaining part may be different.

For example, the control unit 180 may transmit both the first setting information and the second setting information to the other terminal 200.

Also, for example, the controller 180 may distinguish between information included in the first setting information and information included in the second setting information, and information different from the information included in the second setting information, . That is, the control unit 180 may include the mutually matching information only in one of the first setting information and the second setting information, and the different information may be one of the first setting information and the second setting information It can be included in the corresponding information and transmitted.

By including the matching information in any one of the first and second setting information, the amount of data to be transmitted can be reduced.

Also, the controller 180 may transmit the ad-hoc connection information together with a code for allowing the other terminal 200 receiving the ad-hoc connection information to generate the widget or icon shown in Fig.

In the other terminal 200, when the widget or the icon is automatically generated in the other terminal 200 according to the permission of the user of the other terminal 200 or upon receiving the ad-hoc connection information and the code Can be displayed.

The control unit 180 may transmit the ad hoc connection request to the other terminal 200 or may receive the ad hoc connection request from the other terminal 200.

For example, the control unit 180 may transmit the ad hoc connection information to the other terminal 200, and then request the other terminal 200 to perform an ad hoc connection. Alternatively, the controller 180 may be requested to perform the ad hoc connection from the other terminal 200 that has received the ad hoc connection information.

Here, the communication method for the ad hoc connection execution request between the mobile terminal 100 and the other terminal 200 may be performed according to the IEEE 802.11 standard group.

In accordance with the ad-hoc connection request, the controller 180 controls the wireless Internet module 113 based on the ad-hoc connection information to perform an ad-hoc connection with the other terminal 200.

Since the mobile terminal 100 and the other terminal 200 share the ad hoc connection information, they can identify each other through the IP address and the ID, and use the same information included in the ad hoc connection information And can perform the ad hoc connection.
