Abstract

An enhanced data transport system and method for a mobile terminal are provided that may improve transmission rates. A data transport system for a mobile terminal includes a radio frequency unit, a data processing unit, a memory unit, and a control unit. The radio frequency unit establishes a radio frequency channel on the basis of a transmission control protocol parameter received from a mobile communication network. The data processing unit performs encoding/decoding and modulation/demodulation on signals to be transmitted or received through the radio frequency unit. The memory unit stores routines to execute a communication session and the transmission control protocol parameter. The control unit controls signal flows among the radio frequency unit, the data processing unit, and the memory unit, and configures a data transmission scheme according to the transmission control protocol parameter.

Claims

1. A method for data transport in a mobile terminal, comprising:

receiving a transmission control protocol parameter from a mobile communication network;

configuring a data transmission scheme from the transmission control protocol parameter; and

establishing a communication channel with the mobile communication network based on the data transmission scheme.

2. The method of claim 1, wherein the transmission control protocol parameter is a system parameter defining a characteristic of the mobile communication network.

3. The method of claim 1, wherein the transmission control parameter comprises at least one of a transmission window size, a reception window size, and a message segment size.

4. The method of claim 1, wherein configuring a data transmission scheme comprises:

checking at least one of a window size of the mobile communication network and a message segment size of the mobile communication network; and

setting the at least one of the window size and the message segment size of the mobile communication network as a transmission parameter of the data transmission scheme.

5. The method of claim 1, further comprising displaying the transmission control protocol parameter.

6. A method for data transport in a mobile terminal, comprising:

maintaining a first communication channel with a serving network using a first parameter received from the serving network;

determining whether to perform a handover from the serving network to a target network;

determining whether the target network is the same network as the serving network;

receiving, if the target network is not the same network as the serving network, a second parameter from the target network;

reconfiguring a data transmission scheme of the mobile terminal based on the second parameter; and

establishing a second communication channel with the target network.

7. The method of claim 6, wherein the first parameter and the second parameter are parameters defining characteristics of the serving network and the target network, respectively.

8. The method of claim 6, wherein each of the first parameter and the second parameter comprises at least one of a transmission window size, a reception window size, and a message segment size of the corresponding network.

9. The method of claim 6, wherein the first communication channel and the second communication channel are transmission control protocol channels.

10. The method of claim 6, wherein reconfiguring a data transmission scheme comprises:

checking at least one of a window size and a message segment size of the target network from the second parameter; and

setting the at least one of the window size and the message segment size of the target network as a transmission parameter of the data transmission scheme.

11. The method of claim 6, further comprising:

displaying the first parameter; and

displaying a change from the first parameter to the second parameter.

12. A data transport system for a mobile terminal, comprising:

a radio frequency unit to establish a radio frequency channel based on a transmission control protocol parameter received from a mobile communication network;

a data processing unit to perform encoding/decoding and modulation/demodulation on signals to be transmitted or received through the radio frequency unit;

13. The data transport system of claim 12, wherein the control unit configures the data transmission scheme using at least one of a window size and a message segment size included in the transmission control parameter.

14. The data transport system of claim 12, wherein the control unit:

receives a new transmission control protocol parameter from a target network when performing a handover;

determines whether the target network is the same network as the mobile communication network; and

reconfigures the data transmission scheme of the mobile terminal based on the new transmission control protocol parameter, if the target network is not the same network.

15. The data transport system of claim 12, further comprising a display unit to display the transmission control protocol parameter.
