摘要
A method for controlling packet transmission using a bind update message upon handoff of a mobile node in an IPv6 based wireless network comprise the steps of: when a retransmission timeout occurs after transmitting a packet via a transmission control protocol (TCP) connection established with an arbitrary mobile node, storing a currently set congestion control parameter; retrieving each TCP connection established with a relevant mobile node so as to modify the currently set congestion control parameter to form a congestion control value, and performing congestion control; and, when the bind update message from the mobile node is received, retrieving each TCP connection established with the relevant mobile node, and restoring the congestion control parameter to a value stored before performing the congestion control. Thus, after congestion control is performed due to the occurrence of packet loss upon handoff of the mobile node, a state existing before performance of congestion control can be rapidly recovered, thereby reducing degradation in transfer quality due to the handoff of the mobile node.
