Abstract

A mobile communication apparatus configured to communicate with an opposite communication device is provided. The mobile communication apparatus includes a transceiver configured to receive an incoming signal sent from the opposite communication device. The transceiver is configured to produce an interrupt signal upon receiving the incoming signal. The mobile communication apparatus includes a first memory device and a non-volatile second memory device. The mobile communication apparatus includes a controller connected to the transceiver, the first memory device and the second memory device. The controller is configured to perform garbage collection of the second memory device, to load data stored in one of the first memory device and the second memory device into another of the first memory device and the second memory device, to access the first memory device if the transceiver produces the interrupt signal.

Claims

1. 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.

2. The mobile communication apparatus of claim 1, wherein:

the transceiver is further configured to receive an incoming e-mail arrival and the transceiver is further configured to produce a second interrupt signal upon receiving the incoming email arrival;

the controller is further configured to load ring tone data stored in the second memory device into the first memory device; and

the controller is further configured to read the ring tone data from the first memory device upon the transceiver producing the second interrupt signal.

3. The mobile communication apparatus of claim 1, wherein:

the incoming voice call arrival carries incoming data;

the controller is further configured to write the incoming data into the first memory device after the transceiver produces the interrupt signal; and

the controller is further configured to load the incoming data stored in the first memory device into the second memory device except during the garbage collection.

4. A method for avoiding a conflict between garbage collection and memory access of a mobile communication apparatus having a first memory device and a non-volatile second memory device, the mobile communication apparatus configured to communicate with an opposite communication apparatus and configured with a built-in answering machine function, comprising the steps of:

receiving an incoming voice call arrival sent from the opposite communication apparatus;

producing an interrupt signal upon receiving the incoming voice call arrival;

performing garbage collection of the second memory device;

loading data of a message left on the built-in answering machine function stored the first memory device into the second memory device; and

performing an interrupt process upon receiving the incoming voice call arrival,

wherein the performing of the garbage collection continues even while the interrupt process is performed.

5. The method of claim 4, further comprising:

receiving an incoming e-mail arrival sent from the opposite communication apparatus;

producing a second interrupt signal upon receiving the incoming e-mail arrival;

loading ring tone data stored in the second memory device into the first memory device; and

reading the ring tone data from the first memory device upon producing the second interrupt signal.

6. The method of claim 4, wherein:

the incoming voice call arrival carries incoming data;

performing an interrupt process includes writing the incoming data into the first memory device; and

the incoming data is stored in the first memory device and loaded into the second memory device.
