Abstract

A method and apparatus for transmitting data and a method and apparatus for performing a task for process migration are provided. The method of transmitting data includes: determining a data transmission priority using at least one of information relating to data needed to continuously perform a task, that is currently performing, in an external device and information relating to data transmission means; determining transmission methods for each data based on the data transmission priority; and transmitting data to the external device according to the determined transmission methods.

Claims

1. A method of transmitting data, comprising:

determining a data transmission priority using at least one of information relating to data needed to continuously perform a task, that is currently performing, in an external device and information relating to data transmission means;

determining transmission methods for each data based on the data transmission priority; and

transmitting data to the external device according to the determined transmission methods.

2. The method of claim 1, wherein the transmitting data comprises transmitting data having the data transmission priority that is above a threshold order through a first transmission means and data having the data transmission priority that is below the threshold order through a second transmission means.

3. The method of claim 1, wherein the determining transmission methods comprises compressing data having the data transmission priority that is below a threshold order and wherein the transmitting data comprises transmitting uncompressed data having the data transmission priority that is above the threshold order data and the compressed data.

4. The method of claim 1, wherein the transmitting data comprises:

transmitting data having the data transmission priority that is above a threshold order; and

transmitting data having the data transmission priority that is below the threshold order when a transmission request signal is received.

5. The method of claim 1, further comprising setting a standard for determining the data transmission priority based on an external input, and wherein the determining of the data transmission priority further uses the set standard for determining the data transmission priority.

6. The method of claim 1, further comprising receiving input selecting one transmission mode from among transmission modes in which data transmission methods according to the data transmission priority are prescribed, and wherein the determining transmission methods is performed based on the selected transmission mode.

7. The method of claim 1, wherein the information relating to data transmission means comprises at least one of a size of a usable storage space and a data transmission speed and the information relating to data needed to continuously perform a task comprises information relating to at least one of a task execution state, a communication state, an address allocation, and a task control.

21. A computer readable recording medium having embodied thereon a computer program for executing the method of claim 1.

8. A method of performing a task, comprising:

receiving first data having data transmission priority that is above a threshold order according to a predetermined standard from among data needed to continuously perform a task, that is currently performing, in an external device through a first transmission method and receiving second data having data transmission priority that is below the threshold order through a second transmission method; and

continuously performing the task in the external device using the first and second data.

9. The method of claim 8, wherein the receiving comprises receiving the first data through a mobile storage medium which can be removed from and attached to the external device and receiving the second data through a network.

10. The method of claim 8, wherein the data comprises information relating to at least one of a task execution state, a communication state, an address allocation, and a task control.

11. An apparatus for transmitting data, comprising:
