Abstract

On the basis of a state of data transmission and/or data reception in all of or one of intermediate nodes (102, 103) provided on a transport path between a transmission terminal (101) and a reception terminal (104), data to be received by the reception terminal (104) is determined. It is therefore possible to realize audio transport without disconnection and video transport without distortion even under an environment in which a wire section and a wireless section are integrally present.

Claims

1. A data transmission/reception method of transmitting/receiving a data packet between a transmission terminal and a reception terminal in a transport path having a wire section and a wireless section via a gateway which is present in a boundary between the both sections, the method comprising the steps of:

acquiring information regarding a state of data reception and/or data transmission in an intermediate node including the gateway provided on the transport path; and

allowing the reception terminal or the intermediate node to determine data to be received by the reception terminal on the basis of the information regarding the state of data reception and/or data transmission in the intermediate node.

2. The data transmission/reception method of claim 1, further comprising the step of:

determining the data to be received on the basis of at least one of a round trip time between the transmission terminal and the intermediate node, jitter of the round trip time, a packet loss rate at the intermediate node, and a link band of the intermediate node.

3. The data transmission/reception method of claim 1, further comprising the step of:

determining at least one of hierarchically encoded data, data subjected to an error resistivity process and redundant data as the data to be received on the basis of information of packet loss obtained in the intermediate node and information of packet loss obtained in the reception terminal.

4. A data transmission/reception method of transmitting/receiving a data packet between a transmission terminal and a reception terminal via an intermediate node in a transport path having a wireless section, the method comprising the steps of:

acquiring information regarding a transport error in the wireless section; and

allowing the intermediate node to determine an error resistivity strength of data to be transferred on the basis of the information regarding the transport error in the wireless section.

5. The data transmission/reception method of claim 4, further comprising the steps of:

acquiring information regarding a congestion state of the transport path; and

allowing the intermediate node to determine data to be received on the basis of the information regarding the congestion state of the transport path in accordance with given priority.
