FIG. 3A shows a touch input to a soft key through a front surface of a terminal body.

The display unit 151 may operate as an entire area or may be divided into a plurality of areas and operated. In the latter case, the plurality of areas can be configured to operate in association with each other.

For example, an output window 151a and an input window 151b are displayed on the upper and lower portions of the display unit 151, respectively. In the input window 151b, a soft key 151c in which a number for inputting a telephone number or the like is displayed is output.

When the soft keys 135c are touched through the touch pad 135, characters, numbers, symbols, etc. corresponding to the touched soft keys are displayed on the output window 135a. As described above, the touch input through the touch pad 135 is advantageous in that it is possible to prevent the soft key 135c from being covered by the finger when touching, compared with the touch input through the display unit 151. [ In the case where the display unit 151 and the touch pad 135 are formed to be transparent, the fingers located on the rear side of the terminal body can be visually confirmed, thereby enabling a more accurate touch input.

The display unit 151 or the touch pad 135 may be configured to receive a touch input by scrolling, as well as the input method described in the above embodiments. The user can move a cursor or a pointer located on an object displayed on the display unit 151, for example, an icon or the like, by scrolling the display unit 151 or the touch pad 135. [ Further, when the finger is moved on the display portion 151 or the touch pad 135, the path along which the finger moves may be visually displayed on the display portion 151. [ This will be useful for editing the image displayed on the display unit 151. [

One function of the terminal may be executed in response to a case where the display unit 151 (touch screen) and the touch pad 135 are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. The one function may be, for example, activation or deactivation of the display unit 151 or the touch pad 135, and the like.

The proximity sensor 141 described with reference to Fig. 1 will be described in more detail with reference to Fig.

4 is a conceptual diagram for explaining the proximity depth of the proximity sensor.

As shown in FIG. 4, when a pointer such as a finger of a user approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen detects the pointer and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to the distance between the proximity-touched pointer and the touch screen (hereinafter referred to as "proximity depth").

The distance at which the proximity signal is output when the pointer approaches the touch screen is referred to as a detection distance. The proximity signal output from each proximity sensor is simply used by using a plurality of proximity sensors having different detection distances, The depth is known.

In FIG. 4, for example, a cross-section of a touch screen having proximity sensors capable of sensing three proximity depths 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 (d ₀ ), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d ₁ , it is recognized as a proximity touch of the first proximity depth. If the pointer is located on the touch screen at a distance of d ₁ or more and less than distance d ₂ , it is recognized as a proximity touch of the second proximity depth. If the pointer is located on the touch screen at a distance of d ₂ or more and less than d ₃ distance, it is recognized as a proximity touch of the third proximity depth. If the pointer is located at a distance d ₃ or more on the touch screen, it is recognized that the proximity touch is released.

FIG. 5 illustrates an example of a multimedia message, and FIGS. 6 and 7 illustrate a process of transmitting a multimedia message short message. 8 is a flowchart illustrating a multimedia message transmission method according to the present invention. FIGS. 9 and 10 illustrate a method of generating a multimedia message according to an exemplary embodiment of the present invention. Referring to FIG.

5 to 10, a method for transmitting a multimedia message in a mobile terminal according to an exemplary embodiment of the present invention and an operation of a mobile terminal for implementing the method will be described in detail.

When a multimedia message is composed of a plurality of, for example, 10 or more slides, each slide is divided into a start time and an end time. Although the multimedia message has been described as being composed of a plurality of slides, for example, the components of the multimedia message are not limited to the slides. Even if other terms are used, the multimedia messages can be applied to all the components corresponding to the classification criteria have.

Upon receiving the multimedia message designating the mobile terminal 100 as a receiver, the recipient MMS proxy-relay transmits a notification (MMS Notification) indicating that the multimedia message has been received to the mobile terminal 100.

Accordingly, the mobile terminal 100 communicates with the receiving relay server and receives the received multimedia message. Therefore, the reception of the multimedia message to the mobile terminal 100 is actually performed by downloading the multimedia message from the receiving side relay server by the mobile terminal 100 that has received the notification of the arrival of the multimedia message, as described above.

Meanwhile, the originating mobile terminal that has transmitted the multimedia message can request a confirmation report (Read Report) indicating whether the user has read the multimedia message from the recipient's mobile terminal 100.

Accordingly, when the multimedia message downloaded from the mobile terminal 100 is output through the output unit 150, for example, not reproduced and read, or deleted, if the multimedia message is deleted, Send a Read Report.

5 is a diagram showing an example of such an acknowledgment message. Referring to the drawing, the confirmation notification message includes information (Read) indicating whether a multimedia message is confirmed in addition to a message title and a message ID of the received multimedia message. The confirmation notification message may include information (Deleted without Read) indicating that the information has been deleted without confirmation, in addition to information (Read) indicating that the information has been confirmed.

This acknowledgment message may be transmitted in the form of a PDU (Protocol Data Unit). 6 and 7, when an acknowledgment message is transmitted from the receiving mobile terminal 100 to the recipient MMS proxy-relay 200, an 'M-read-recind PDU' To the originating relay server 300. The originating relay server 300 having received the message is transmitted to the originating mobile terminal 400 in the format of 'M-read-orig.ind PDU'.

8, when the multimedia message is received through the wireless communication unit 110 of the receiving-side mobile terminal 100 (S510), the controller 180 determines whether the received multimedia message is transmitted to the output unit 150 of the mobile terminal 100 ) (Step S520).

Meanwhile, when the multimedia message is composed of a plurality of slides, the controller 180 may determine whether or not output for each slide is performed (S530).

Since each slide is distinguished by the start time and the end time, the control unit 180 can determine whether or not each slide is output. In addition, the control unit 180 determines whether each slide is output from the start time to the end time, And whether or not the end time has been output can be determined.

Accordingly, the control unit 180 confirms whether or not each slide is output, and generates confirmation state value information by replacing each of the slides with a binary corresponding value corresponding to the output of the slideshow (S540). The confirmation status value information can be displayed as 'TRUE' or 'T', for example, or 'FALSE' or 'T' if not output.

The control unit 180 generates an acknowledgment message in the form of 'M-read-rec.ind PDU', for example, including the status information for confirming whether or not to output each slide, in step S550, and transmits the confirmation notification message through the wireless communication unit 110 To the receiving-side relay server 200 (S560).

9 and 10 are views showing an example of a read report (Read Report). 9 shows the format of 'M-read-rec.ind PDU' in the acknowledgment message, and FIG. 10 shows the format of 'M-read-orig.ind PDU'.

Referring to the drawing, a confirmation status item, i.e., an 'X-Mms-Read-Status' item exists in the header of the confirmation notification message, and the check status value information indicating whether the received multimedia message is output is' X- Mms-Read-Status' item.

Specifically, confirmation status value information can be recorded in the 'X-Mms-Read-Status' item in the form of 'X-Mms-Read-Status:' read ': SLIDE # -Read Status'.

That is, when the multimedia message is composed of five slides, and the first, second and third slides are outputted and the fourth and fifth slides are not outputted, 'X-Mms-Read-Status' Status: 'read': S1-TRUE, S2-TRUE, S3-TRUE, S4-FALSE, S5-FALSE.

As another example, the confirmation status value information is recorded in the 'X-Mms-Read-Status' item as' X-Mms-Read-Status: read': SLIDE # -Start time read status: End time read status' .

That is, the multimedia message is composed of 5 slides in total, and the first slide is output from the beginning to the end, and the user confirms that the first and second slides are outputted only for the first time and not outputted to the end, Read-Status: Read: S1-T: T, S2-T: F, S3-T: F, S4-F: F, and S5-F: F '.
