Abstract

A mobile terminal and group chat controlling method thereof are disclosed, by which a chat content transceived in an performed group chat after a join-impossible state can be received in the course of performing the group chat if impossible to join the group chat. The present invention includes performing a group chat with a plurality of counterparts, displaying a chat window of the performed group chat, if the mobile terminal is impossible to join the group chat (i.e., if the mobile terminal enters a join-impossible state) in the course of performing the group chat, receiving chat contents transceived among a plurality of the counterparts in the performed group chat after the join-impossible state, and displaying the received chat contents.

Claims

1. A mobile terminal comprising:

a wireless communication unit configured to perform a group chat with a plurality of counterparts;

a display unit configured to display a chat window of the performed group chat; and

a controller configured to determine whether the mobile terminal enters a join-impossible state in the course of performing the group chat, the controller further configured to control the wireless communication unit to receive chat contents transceived among a plurality of the counterparts in the performed group chat after the join-impossible state in case of the join-impossible state and control the display unit to display the received chat contents.

2. The mobile terminal of claim 1, wherein the join-impossible state includes at least one of a state of logging out of a communication service for performing the group chat and a state of ending the group chat during logging in to the communication service.

3. The mobile terminal of claim 1, wherein the wireless communication unit further receives the chat contents transceived in the performed group chat before the join-impossible state under control of the controller.

4. The mobile terminal of claim 3, wherein the display unit distinguishably displays the chat contents before the join-impossible state and the chat contents after the join-impossible state under control of the controller.

5. The mobile terminal of claim 1, wherein the controller sets a reception environment of the chat contents to receive after the join-impossible state and wherein the wireless communication unit receives the chat contents to correspond to the set reception environment under control of the controller.

6. The mobile terminal of claim 1, wherein the wireless communication unit receives the chat contents to correspond to a transmission environment set by each of a plurality of the counterparts in association with the chat contents to receive after the join-impossible state under control of the controller.

7. The mobile terminal of claim 1, wherein in case of entering the join-impossible state, the controller switches the displayed chat window from an instant messaging window to a message chat window.

8. The mobile terminal of claim 7, wherein the wireless communication unit transmits a message to a plurality of the counterparts and wherein the display unit displays a message content included in the transmitted message as the chat content within the message chat window under control of the controller.

9. The mobile terminal of claim 1, wherein in case of returning to a join-possible state, the wireless communication unit rejoins the performed group chat under control of the controller and wherein the display unit displays the chat window of the rejoined group chat under the control of the controller.

10. The mobile terminal of claim 9, wherein the chat window of the rejoined group chat includes the chat contents transceived among a plurality of the counterparts between the join-impossible state and the join-possible state.

11. The mobile terminal of claim 10, wherein in case of transmitting a message to a plurality of the counterparts in the join-impossible state, the chat window of the rejoined group chat includes a message content included in the transmitted message as the chat contents of the rejoined group chat.

12. The mobile terminal of claim 11, wherein the chat window of the rejoined group chat includes the message content, in which a transmission time of the message is enumerated with reference to an input time of the chat content, as the chat content.

13. A mobile terminal comprising:

a wireless communication unit configured to perform a group chat with a plurality of counterparts;

a display unit configured to display a chat window of the performed group chat; and

a controller configured to determine whether the at least one of a plurality of the counterparts enters a join-impossible state, the controller further configured to control the wireless communication unit to transmit a chat content transceived in the performed group chat after the join-impossible state to the at least one counterpart in the join-impossible state.

14. The mobile terminal of claim 13, wherein the controller sets a transmission environment of the chat content to transmit after the join-impossible state and wherein the wireless communication unit transmits the chat content to correspond to the set transmission environment under control of the controller.

15. The mobile terminal of claim 13, wherein if a transmission of the chat content is granted by a remaining chatter of the group chat, the wireless communication unit transmits the chat content transceived in the group chat after the join-impossible state to at least one of the counterparts in the join-impossible state under control of the controller.

16. The mobile terminal of claim 13, wherein the wireless communication unit transmits the chat content of a chatter having granted a chat content transmission among remaining chatters of the group chat under control of the controller.

17. The mobile terminal of claim 13, wherein the wireless communication unit transmits the chat content transceived among chatters remaining in the group chat by real time or with a predetermined time interval under control of the controller.

18. The mobile terminal of claim 13, wherein the display unit displays a normal join-impossible state or an abnormal join-impossible state for each of the at least one counterpart in the join-impossible state under control of the controller.

19. A method of controlling a group chat in a mobile terminal, comprising the steps of:

performing a group chat with a plurality of counterparts;

displaying a chat window of the performed group chat;

if the mobile terminal enters a join-impossible state in the course of performing the group chat, receiving chat contents transceived among a plurality of the counterparts in the performed group chat after the join-impossible state; and

displaying the received chat contents.

20. The method of claim 19, further comprising the step of setting a reception environment of the chat contents to receive after the join-impossible state, wherein the receiving step comprises the step of receiving the chat contents to correspond to the set reception environment.

21. The method of claim 19, further comprising the steps of:

in case of the join-impossible state, switching the displayed chat window to a message chat window from an instant messaging chat window;

receiving an input of a message content;

transmitting a message including the inputted message content to a plurality of the counterparts; and

displaying the message content included in the transmitted message as the chat content within the message chat window.

22. The method of claim 19, further comprising the steps of:

in case of returning to a join-possible state, rejoining the performed group chat; and

displaying the chat window of the rejoined group chat.

23. A method of controlling a group chat in a mobile terminal, comprising the steps of:

performing a group chat with a plurality of counterparts;

displaying a chat window of the performed group chat;

setting a transmission environment of a chat content to transmit after a join-impossible state to the performed group chat; and

if the at least one of a plurality of the counterparts enters the join-impossible state, transmitting a chat content transceived in the performed group chat after the join-impossible state to the at least one counterpart in the join-impossible state.

24. The method of claim 23, wherein the chat window displaying step comprising the step of displaying a normal join-impossible state or an abnormal join-impossible state for each of the at least one counterpart in the join-impossible state.
