Abstract

A mobile communication terninal comprising an interface for allowing scheduling of a first time period; a timer for monitoring a beginning and an end for the first time period; and a controller for switching the mobile communication terminal to a first mode, at the beginning of the first time period, and for switching the mobile communication terminal to a second mode at the end of the first time period, wherein in the first mode, the mobile communication terminal cannot communicate over a mobile communication network.

Claims

1. A method for controlling a communication mode of a mobile communication terminal, the method comprising:

receiving a deactivation time for deactivating the communication mode of the mobile communication terminal, wherein the mobile communication terminal can be configured to be used for data communication, but not used for voice communication when the communication mode is deactivated while the mobile communication terminal can be used for voice communication to at least one designated contact even when the communication mode is deactivated;

receiving a reactivation time for reactivating the communication mode;

deactivating the communication mode upon reaching the deactivation time;

displaying time remaining until the reactivation time;

prompting to confirm or deny reactivation of the communication mode upon reaching the reactivation time;

determining whether a mobile communication service is available by scanning a communication channel responsive to an input confirming the reactivation of the communication mode;

reactivating the communication mode upon the reaching the reactivation time and determining that the mobile communication service is available; and

delaying the reactivation of the communication mode when mobile communication service is unavailable or the reactivation of the communication mode is denied,

wherein features of the mobile communication terminal that are unrelated to the communication mode are usable when the communication mode is deactivated, the features that are unrelated to the communication mode comprising at least one of a game function and a multimedia function.

2. The method of claim 1, wherein when the communication mode is deactivated, the mobile communication terminal cannot communicate over a mobile communication network.

3. The method of claim 1, wherein the communication channel is at least one of a pilot channel and a synchronization channel in a CDMA based mobile communication network.

4. The method of claim 1, wherein the mobile communication terminal can be used for data communication when the communication mode is deactivated.

5. The method of claim 1, wherein at least one of the reactivation time and the deactivation time can be updated.

19. The method of claim 1, wherein the data communication comprises at least one of short message service (SMS) or multimedia messaging service (MMS).

20. The method of claim 1, further comprising:

displaying elapsed time after deactivating the communication mode.

21. The method of claim 1, wherein the deactivated communication mode can be manually reactivated prior to the reactivation time responsive to a special code received from a user of the mobile communication terminal.

6. A method of controlling a communication mode of a mobile communication terminal, the method comprising:

scheduling a first time period during which the mobile communication terminal switches to a first mode;

determining whether a mobile communication service is available by scanning a communication channel after the first time period expires;

switching from the first mode to a second mode upon expiration of the first time period and determining that the mobile communication service is available; and

remaining in the first mode until the mobile communication terminal detects that the mobile communication service is available after the first time period expires,

wherein the mobile communication terminal can partially communicate over a mobile communication network and non-communication related features of the mobile communication terminal remain available to a user in the first mode, the non-communication related features comprising at least one of a game function and a multimedia function, and the mobile communication terminal can communicate over the mobile communication network in the second mode,

wherein communication to at least one designated contact can be initiated by a user of the mobile communication terminal even in the first mode in which communication to non-designated contacts is blocked.

22. The method of claim 6, further comprising:

displaying elapsed time of the first time period during the first mode.

23. The method of claim 6, further comprising:

displaying time remaining until the expiration of the first time period.

24. The method of claim 6, wherein the mobile communication mode can be manually switched to the second mode prior to the expiration of the first time period responsive to a special code received from a user of the mobile communication terminal.

7. A mobile communication terminal comprising:

an interface configured to receive an input for scheduling a first time period;

a timer configured to monitor a beginning and an end of the first time period; and

a controller configured to;

switch the mobile communication terminal to a first mode at the beginning of the first time period;

prompt to confirm or deny switching to a second mode at the end of the first time period;

determine whether the mobile communication terminal is in a service area by scanning a communication channel responsive to an input confirming the switching to the second mode;

switch the mobile communication terminal to the second mode at the end of the first time period upon determining that the mobile communication terminal is in the service area; and

delay switching to the second mode when mobile communication terminal is not in the service area or the switching to the second mode is denied,

wherein the mobile communication terminal cannot communicate over a mobile communication network and non-communication related features of the mobile communication terminal are usable in the first mode, the non-communication related features comprising at least one of a game function and a multimedia function.

8. The mobile communication terminal of claim 7, wherein the controller comprises first and second controllers, the first controller controlling at least one of a receiver and a transmitter of the mobile communication terminal such that the at least one of the receiver and the transmitter is deactivated in the first mode.

9. The mobile communication terminal of claim 8, wherein the controller further comprises a third controller configured to determine whether the mobile communication terminal is in the service area, and to maintain the at least one of the receiver and the transmitter in a deactivated state when the mobile communication terminal switches to the second mode if the mobile communication terminal is not in the service area at the end of the first time period.

10. The mobile communication terminal of claim 7, wherein the mobile communication terminal can communicate over the mobile communication network in the second mode.

11. The mobile communication terminal of claim 7, wherein the mobile communication terminal remains in the first mode until the mobile communication terminal detects that a mobile communication service is available in the service area at the end of the first time period.

12. The mobile communication terminal of claim 7, wherein the communication channel is at least one of a pilot channel and a synchronization channel in a CDMA based mobile communication network.

25. The mobile communication terminal of claim 7, further comprising:

a display configured to display elapsed time of the first time period or time remaining until the end of the first time period during the first mode.

26. The mobile communication terminal of claim 7, wherein the controller is further configured to switch to the second mode before the end of the first time period responsive to a special code received from a user of the mobile communication terminal.

27. The mobile communication terminal of claim 7, wherein communication to at least one designated contact can be initiated by a user of the mobile communication terminal even in the first mode in which communication to non-designated contacts is blocked.
