Accordingly, the user may not only set a reservation time through the displayed window 1520, but also set whether to notify the user of a message reservation transmission at the set reservation time (or a predetermined time earlier than the reservation time). have.

When the reservation setting condition is set, the mobile terminal 100 may transmit the created message and message transmission reservation information (including the set reservation setting condition) to the IPTV terminal 510.

Accordingly, the IPTV terminal 100 may transmit the corresponding message to the counterpart terminal 520 at the reservation time included in the message transmission reservation information.

Meanwhile, when the reservation transmission notification is set in FIG. 15C, the mobile terminal 100 may receive a selection from the user to transmit a message scheduled to be transmitted to the counterpart terminal 520 at the set reservation time (FIG. 15D). When transmission ('Yes') is selected in Fig. 15D, the mobile terminal 100 transmits a transmission command signal for a message reserved for transmission to the IPTV terminal 510, and the IPTV terminal 510 transmits the transmission command signal. In response to receiving the message, the reserved message can be transmitted to the counterpart terminal 520.

In addition, the mobile terminal 100 may change or cancel the transmission scheduled message before the transmission scheduled message is transmitted from the IPTV terminal 100 to the counterpart terminal 520 under the control of the controller 180. have. Accordingly, the IPTV terminal 100 receives the change information or the cancellation information for the transmission scheduled message from the mobile terminal 100 and transmits the transmission scheduled message according to the received change information or the cancellation information. Can be performed.

Hereinafter, a process of changing or canceling message reservation transmission using the IPTV terminal 510 in relation to the transmission step S630 will be described with reference to FIGS. 16 to 20.

The mobile terminal 100 may receive a menu item 1601 for selecting a menu item 1601 for managing a message reserved for transmission to the IPTV terminal 100 through a menu search (FIG. 16).

Here, the mobile terminal 100 may request the IPTV terminal 510 for information (including a transmission reservation message list) about a message that is scheduled to be transmitted, and as a result, receive information about a message that has been scheduled for transmission (FIG. 17). Of course, such a request and reception process may be unnecessary when information on a message reserved for transmission is shared between the mobile terminal 100 and the IPTV terminal 510.

In some cases, the mobile terminal 100 may transmit valid authentication information to the IPTV terminal 100 to authenticate the user's management authority for the message scheduled to be transmitted to the IPTV terminal 100. And, only when the management authority is authenticated, the message reserved for transmission to the IPTV terminal 100 can be changed or canceled using the mobile terminal 100.

The mobile terminal 100 may display a transmission reservation message list including information on at least one message reserved for transmission (reservation timing, part of message contents, etc.) (FIG. 18A). When the first reservation message 1801 is selected in FIG. 18A, the mobile terminal 100 may receive a selection from the user whether to change or cancel the first reservation message 1801 (FIG. 18B).

When the change is selected in FIG. 18B, the mobile terminal 100 displays the first reservation message 1801 on the screen, and the contents of the first reservation message 1801, caller information, receiver information, and reservation according to the user's selection. At least one piece of information may be changed (see FIG. 19A).

The mobile terminal 100 may transmit the updated information on the first reservation message 1801 or the first reservation message 1801 updated according to the changed information to the IPTV terminal 510.

Accordingly, the IPTV terminal 510 may store the first reserved message 1801 previously stored on the basis of the changed information on the updated first reserved message 1801 or the first reserved message 1801 received from the mobile terminal 100. ) Can be updated. In this case, the IPTV terminal 510 may distinguish the first reservation message 1801 using the unique information provided in the first reservation message 1801. The IPTV terminal 510 may transmit a notification whether the first reservation message 1801 is updated to the mobile terminal 100.

Accordingly, the mobile terminal 100 may output information 1910 indicating whether the first reservation message 1801 has been successfully updated when receiving the update notification signal from the IPTV terminal 510.

Meanwhile, when canceling is selected in FIG. 18B, the mobile terminal 100 may cancel the reservation transmission of the first reservation message 1801. The mobile terminal 100 may transmit the cancellation information for the first reservation message 1801 to the IPTV terminal 510.

Accordingly, the IPTV terminal 100 may delete the first reservation message 1801 from the reserved transmission target message list.

Of course, although not shown in the figure, the user can directly retrieve and change or cancel the transmission reservation message in the IPTV terminal 510. In this case, the IPTV terminal 510 may transmit the change or cancellation information on the transmission reservation message to the mobile terminal 100.

Hereinafter, referring to FIGS. 21A and 21B, a process of using the Internet free text transmission service in relation to the transmission step S630 will be described.

In the present invention, the message transmission to the counterpart terminal 520 may be performed using a free message transmission service provided on the Internet.

Here, the free message transmission service provided on the Internet may be provided by at least one provider, respectively, and may be provided by an IPTV provider that provides Internet service to the IPTV terminal 510.

Accordingly, the user can select a free message transmission service to be used for message transmission from the IPTV terminal 510 to the counterpart terminal 520, as shown in FIG. 21A.

Alternatively, the free message transmission service provided on the Internet may differently set the number of free message transmissions provided to each of the mobile terminal 100 and the IPTV terminal 510.

Thus, as shown in FIG. 21B, the user can select either a free message transmission service designated for the mobile terminal 100 or a free message transmission service designated for the IPTV terminal 510. When the free message transmission service designated in the IPTV terminal 510 is selected, the number of free message transmissions designated in the IPTV terminal 510 may be subtracted and the message may be transmitted from the IPTV terminal 510 to the counterpart terminal 520. Alternatively, when the free message transmission service designated by the mobile terminal 100 is selected, the number of free message transmissions designated by the mobile terminal 100 is subtracted, and the counterpart terminal (the counterpart terminal) is not transmitted through the IPTV terminal 510. The message can be sent directly to 520.

Returning to FIG. 6, when the mobile terminal 100 fails to transmit a message in the transmission step S630 (S640), the IPTV terminal 510 determines whether the first connection between the mobile terminal 100 and the IPTV terminal 510 has failed. ) And whether the second connection between the counterpart terminal 520 has failed (S650).

Failure of the first and second connections may occur prior to or during the transmission step (S630).

In case of the first connection failure, the mobile terminal 100 cannot transmit the received data or the message including the received data to the IPTV terminal 510. In this case, the mobile terminal 100 may not start the transmission operation of the received data or the message including the received data, or may confirm the failure of the first connection as the ongoing transmission operation is stopped.

Alternatively, in case of failure of the second connection, the IPTV terminal 510 normally receives a message including data or data from the mobile terminal 100, but cannot transmit the message to the counterpart terminal 520. In this case, as the mobile terminal 100 receives a signal (or message) indicating a message transmission failure from the IPTV terminal 510 to the counterpart terminal 520, the mobile terminal 100 may identify the failure of the second connection.

When the message transmission to the counterpart terminal 520 fails due to the failure of the first or second connection, the mobile terminal 100 can distinguish which of the first and second connections has failed.

As a result of the determination, when the first connection fails, the mobile terminal 100 selects whether to retransmit the message (or data) to the IPTV terminal 510 under the control of the controller 180 (S660).

In the selection step S660, the mobile terminal 100 selects whether to resend the message to correspond to the message retransmission selection signal received from the user through the user input unit 130, or whether or not to resend the message when the message transmission fails. You can choose whether to resend the message to correspond to the specified action.

When the message retransmission is selected in the selection step S660, the mobile terminal 100 may retransmit the message (or data) that has failed transmission (S640) to the IPTV terminal 510. Accordingly, the IPTV terminal 510 transmits a message received from the mobile terminal 100 to the counterpart terminal 520, or composes a message including data received from the mobile terminal 100 to the counterpart terminal 520. I can send it.

In this regard, it is shown in detail in FIGS. 22A and 22B.

On the other hand, when the second connection fails as a result of the determination, the mobile terminal 100 selects whether to retransmit the message from the IPTV terminal 510 to the counterpart terminal 520 under the control of the controller 180 (S670).

In the selection step S670, the mobile terminal 100 selects whether to resend the message so as to correspond to the message retransmission selection signal received from the user through the user input unit 130, or whether the message is resent when the message transmission fails. You can choose whether to resend the message to correspond to the specified action.

When the message retransmission is selected in the selection step S670, the mobile terminal 100 may transmit a retransmission command signal of the message that has failed transmission (S640) to the IPTV terminal 510. Accordingly, the IPTV terminal 510 may retransmit a message that fails to be transmitted (S640) to the counterpart terminal 520 in response to the retransmission command signal of the message from the mobile terminal 100.

In this regard, it is shown in detail in FIGS. 23A and 23B.
