6 is a flowchart illustrating a method of providing a PTT service using a sound effect in a mobile device according to an embodiment of the present invention.

Referring to FIG. 6, when the PTT application is selected by the user, the mobile device switches to the PTT communication mode (S601).

The mobile device enters the user-selected PTT chat room and confirms whether the entered PTT chat room participant is online (S603 to S605).

At this time, if there is a participant in the on-line state, predetermined information indicating that there is an on-line participant may be displayed on one side of the PTT chat screen.

As a result of step 605, if the mobile device is in the on-line state, the mobile device can request the talk right to the predetermined PTT server and occupy the microphone (S607 to S609). Here, the voice request may be initiated when the voice call button 240 is touched or held by the user according to the setting of the talk menu 520 while the voice is being held.

Thereafter, the mobile device confirms whether the sound effect is selected by the user (S611).

As a result, when the sound effect is selected, the mobile device reproduces the selected sound effect as the PTT call sound background and transmits the sound effect through the PTT channel occupied by the counterpart terminal on-line to the corresponding PTT chat room (S613).

At this time, the mobile device can transmit the user voice inputted through the occupied microphone together with the effect sound reproduced through the occupied PTT channel (S615). Here, the PTT channel may use RTP (Real Time Protocol) for real-time voice transmission. The PTT channel according to another embodiment of the present invention may be a channel for transmitting a recorded voice message in a multimedia message form (for example, a multimedia message service (MMS) message) for a predetermined period.

The mobile device according to another embodiment of the present invention may retain the voice for a certain period of time even after the reproduction of the background sound is completed. That is, the microphone may be occupied for a predetermined time after the background sound is reproduced, and the voice message may be transmitted to the other party.

In addition, the mobile device according to the present invention may output a predetermined notification sound when the voice is acquired or the voice is revoked. Accordingly, the user can audibly confirm whether or not the voice can be acquired and canceled through the notification sound.

The mobile device according to another exemplary embodiment of the present invention may display voice through the color of the voice button 240 when the voice is verifiable or the voice is revoked. For example, when the voice origination button 240 is green, it is possible to obtain a voice, when the voice origination button 240 is orange, the voice is occupied, when the voice origination button 250 is gray, Can be defined as being in an occupied state.

If the user has terminated the utterance, the mobile device ends voice utterance (S617). Here, when the speech is terminated, the mobile device can transmit a predetermined control signal indicating that the speech is finished to the PTT server, so that another chat room participant can occupy the microphone.

7 is a configuration diagram of a PTT service providing system according to an embodiment of the present invention.

7, a PTT service providing system according to the present invention includes a mobile device 710, a wireless communication network 720, a PTT server 730, a message transmission server 740, a presence server 750, An effect content server 760, an application store 770, a map server 780, and the like.

The mobile device 710 can establish or release a session for the PTT service in cooperation with the PTT server 730. [

In addition, the mobile device 710 may provide subscriber information in conjunction with the presence server 750. [ Here, the subscriber information may include information indicating whether the corresponding mobile device 710 is connected to a specific PTT chat room. That is, the presence server 750 can check whether the participants of the PTT chat room are on-line and provide the same to the PTT server 730. The presence server 750 may also obtain location information of the mobile device 710 and provide it to the PTT server 730.

The PTT server 730 can confirm whether the PTT chat room participant is online or not and transmit the PTT voice message and the sound effect received from the mobile device 710 to the counterpart mobile device 710 that has entered the corresponding PTT chat room. At this time, the PTT server 730 may transmit the PTT voice and / or sound effect received from the specific mobile device to the receiving mobile device in cooperation with the message transmitting server 740.

In addition, the PTT server 730 may transmit the current location information of the other party mapped on the map to the corresponding mobile device 710 in cooperation with the map server 780.

The mobile device 710 can display the effect sound store screen 400 when the new content browse button 340 of the effect sound selection screen 300 is selected.

At this time, the user can purchase the desired sound effect content, and download the sound effect content purchased by his or her mobile device 710. Here, the purchased sound effect contents can not be used by persons who are not authenticated as DRM contents.

The sound effect content server 760 acquires the DRM contents for the PTT sound effect from the App store 770 such as U + store, Google PlayStore, and the like, and transmits the obtained DRM contents to the corresponding mobile device 710 Lt; / RTI >

In addition, the sound effect content server 760 may classify the acquired DRM content by theme and provide information on which topic the corresponding DRM content corresponds to in a purchase request of the user. Accordingly, when the DRM content is received from the sound effect content server 760, the mobile device 710 can store the DRM content in a database by topic.

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.

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.
