Abstract:
A method for managing resources and handling an operation error is disclosed. The method analyzes an error event when the error event occurs in an operation being performed, determines whether memory resources are insufficient, stores information on the operation, and stops the operation, when the analyzed error event is a resource-related event, and reallocates resources to the stopped operation and restores and performs the stopped operation using the reallocated resources. Therefore, an abnormal termination of an operation caused by a shortage of available resources can be prevented, thereby improving availability of a service and utilization of system resources.

PURPOSE: An apparatus and a method for providing near field communication for a mobile device is provided to minimize the power consumption of a mobile terminal for a non-contact service by providing the non-contact service only through one near field communication device of a chip or an IC card type. CONSTITUTION: A USB signal processing unit (100) converts signals of a mobile terminal into processible information in a central processing unit (108). The USB signal processing unit converts the value offered from the central processing unit into signals to be transmitted to a USB interface. An analog signal processing unit (102) converts analog signals from external devices into digital signals. The analog signal processing unit converts digital signals from the central processing unit into analog signals and transmits the signals to an antenna. A non-contact digital signal processing unit (104) converts the processed value in the central processing device unit into digital signals and transmits signals. A reset signal control unit (106) generates a system reset signal in response to a non-contact reset signal generated from the analog signal processing unit.
