Appratus and method for controlling state mode in an wireless terminal

The present invention relates to a device and a method for controlling a standby mode in which a communication processor performs a predetermined operation by being switched between a sleep mode and an active mode in a wireless terminal provided with an application processor and the communication processor. To this end, when switching to the sleep mode is required, a normal mode, in which operation is performed on the basis of an external memory, is switched to an internal mode in which operation is performed on the basis of an internal memory, and then a control program according to an active mode in the internal memory is loaded from the internal memory in response to the switching to the internal mode. Among dependent variables and parameters used in the normal mode, a dependent variable and a parameter to be used in the control program according to the loaded idle mode are set, and waking up from the sleep mode is periodically performed so as to perform an operation due to running of the control program according to the idle mode loaded in the internal memory.
