Abstract

A power control apparatus of a user terminal in a communication system. A transmission module transmits a signal, a reception module receives a signal, and a power supply module performs power supply to modules included in the user terminal under a predetermined control. A control module controls an operation of the power supply module to transition from a Power-ON state to a Power-Active-SAVE state upon detecting a first event causing a transition from the Power-ON state to the Power-Active-SAVE state, and to supply limited power to the control module, the transmission module and the reception module among the modules included in the user terminal.

Claims

1. A power control method of a user terminal in a communication system, the method comprising:

transitioning from a Power-ON state to a Power-Active-SAVE state upon detecting a first event causing a transition from the Power-ON state to the Power-Active-SAVE state; and

controlling to supply limited power to a control module, a transmission module and a reception module among the modules included therein.

2. The power control method of claim 1, wherein the limited power is the minimum power needed to decode a message received from the communication system.

3. The power control method of claim 1, wherein the first event occurs when at least one of:

i) a user directly inputs a power state using a power-related button; and

ii) there is no data transmission and no data reception for a predetermined time.

4. The power control method of claim 1, further comprising:

transitioning from the Power-Active-SAVE state to the Power-ON state upon detecting a second event causing a transition from the Power-Active-SAVE state to the Power-ON state; and

controlling to supply power to all modules included therein.

5. The power control method of claim 4, wherein the second event occurs when a user directly inputs a power state using a power-related button or receives a message from the communication system.

6. The power control method of claim 5, wherein the message is a message for requesting the user terminal in the Power-Active-SAVE state to resume the wireless communication connection.

7. A power control apparatus of a user terminal in a communication system, the apparatus comprising:

a transmission module for transmitting a signal;

a reception module for receiving a signal;

a power supply module for performing power supply to modules included in the user terminal under a predetermined control; and

a control module for controlling an operation of the power supply module to transition from a Power-ON state to a Power-Active-SAVE state upon detecting a first event causing a transition from the Power-ON state to the Power-Active-SAVE state, and to supply limited power to the control module, the transmission module and the reception module among the modules included in the user terminal.

8. The power control apparatus of claim 7, wherein the limited power is the minimum power needed to decode a message received from the communication system.

9. The power control apparatus of claim 7, wherein the first event occurs when at least one of:

i) a user directly inputs a power state using a power-related button; and

ii) there is no data transmission and no data reception for a predetermined time.

10. The power control apparatus of claim 7, wherein the control module controls the power supply module to transition from the Power-Active-SAVE state to the Power-ON state upon detecting a second event causing a transition from the Power-Active-SAVE state to the Power-ON state, and to supply power to all modules included in the user terminal.

11. The power control apparatus of claim 10, wherein the second event occurs when a user directly inputs a power state using a power-related button or receives a message from the communication system.

12. The power control apparatus of claim 11, wherein the message is a message for requesting the user terminal in the Power-Active-SAVE state to resume the wireless communication connection.
