Control method and system in a communication system

Abstract

Disclosed is a power control method by a first device in a communication system. In the power control method, a first communication module is activated by supplying power to the first communication module without supplying power to the second communication module, data is received using the first communication module, the second communication module is activated by supplying power to the second communication module for transmitting the data to a second device using the second communication module, the data is transmitted to the second device using the second communication module, and the power supply to the second communication module is interrupted, if the data transmission is complete.

What is claimed is: 
     
         1 . A power control method by a first device in a communication system, the method comprising:
 supplying power to a first communication module in order to receive data using the first communication module;   receiving the data using the first communication module;   supplying power to a display module of the first device in response to the reception of the data;   supplying power to a second communication module in response to detection of user input information from the display module, in order to transmit the data to a second device using the second communication module, the second device interacting with the first device and being separate from the first device;   transmitting the data to the second device using the second communication module; and   interrupting the power supply to the second communication module after the data transmission is completed.
