Patent ID: 8295875

Claim:
A mobile communication apparatus configured to communicate with an opposite communication apparatus and configured with a built-in answering machine function, comprising: a transceiver configured to receive an incoming voice call arrival sent from the opposite communication apparatus, the transceiver configured to produce an interrupt signal upon receiving the incoming voice call arrival; a first memory device; a non-volatile second memory device; a controller connected to the transceiver, the first memory device and the second memory device, the controller configured to perform garbage collection of the second memory device, the controller configured to load data stored in one of the first memory device and the second memory device into the other of the first memory device and the second memory device, the controller further configured to perform an interrupt process upon receiving the incoming voice call arrival, the controller further configured to write data of a message left on the built-in answering machine function into the first memory device after the transceiver produces the interrupt signal, the controller further configured to load the data of the message stored in the first memory device into the second memory device except during the garbage collection, wherein the controller is configured to continue performing the garbage collection even while performing the interrupt process.
