Abstract

A method of saving power in a mobile communication terminal capable of connection to an external device for communicating data is provided. The method comprises connecting an input port of the mobile communication system to an output port of the external device, switching the mobile communication terminal to a first mode, if a predetermined amount of data is not communicated between the input and output ports, detecting whether data is communicated between the input and output ports, while the mobile communication terminal is in the first mode, and switching the mobile communication terminal into a second mode, in response to detecting data communication between the input and the output ports.

Claims

1. A method for changing modes of a mobile terminal, the method comprising:

establishing a wireless connection for the mobile terminal;

converting a mode of the mobile terminal from a first mode into a second mode when input from a user input device of the mobile terminal has not been received for a predetermined time period, wherein the first mode permits the mobile terminal to engage in voice and data communication via the wireless connection, and wherein the second mode permits the mobile terminal to receive incoming signals via the wireless connection; and

converting a mode of the mobile terminal from the second mode into the first mode when input is received by the user input device.

2. The method according to claim 1, further comprising:

converting a mode of the mobile terminal from the first mode into the second mode when input via the wireless connection has not been received for a predetermined time period.

3. The method according to claim 1, further comprising:

converting a mode of the mobile terminal from the second mode into the first mode responsive to input received from the user input device.

4. The method according to claim 1, wherein the user input device comprises a keypad.

5. A mobile terminal, comprising:

a user input device;

a display; and

a processor for changing modes of the mobile terminal, wherein the processor is configured to;

establish a wireless connection for the mobile terminal;

convert a mode of the mobile terminal from a first mode into a second mode when input from the user input device of the mobile terminal has not been received for a predetermined time period, wherein the first mode permits the mobile terminal to engage in voice and data communication via the wireless connection, and wherein the second mode permits the mobile terminal to receive incoming signals via the wireless connection; and

convert a mode of the mobile terminal from the second mode into the first mode when input is received by the user input device.

6. The mobile terminal according to claim 5, wherein the processor is further configured to:

convert a mode of the mobile terminal from the first mode into the second mode when input via the wireless connection has not been received for a predetermined time period.

7. The mobile terminal according to claim 5, wherein the processor is further configured to:

convert a mode of the mobile terminal from the second mode into the first mode responsive to input received from the user input device.

8. The mobile terminal according to claim 5, wherein the user input device comprises a keypad.

9. A mobile terminal, comprising:

a user input device;

a display; and

means for establishing a wireless connection for the mobile terminal;

means for converting a mode of the mobile terminal from a first mode into a second mode when input from the user input device of the mobile terminal has not been received for a predetermined time period, wherein the first mode permits the mobile terminal to engage in voice and data communication via the wireless connection, and wherein the second mode permits the mobile terminal to receive incoming signals via the wireless connection; and

means for converting a mode of the mobile terminal from the second mode into the first mode when input is received by the user input device.

10. The mobile terminal according to claim 9, further comprising:

means for converting a mode of the mobile terminal from the first mode into the second mode when input via the wireless connection has not been received for a predetermined time period.

11. The mobile terminal according to claim 9, further comprising:

means for converting a mode of the mobile terminal from the second mode into the first mode responsive to input received from the user input device.
