Abstract
A delayed acknowledgement transmission method and an apparatus are provided for improving communication performance of a system and a terminal by delaying an ACKnowledgement (ACK) transmission of the terminal in a handover procedure. The method includes transmitting an acknowledgement corresponding to a segment immediately upon receipt of the segment, detecting a delay condition event which is triggered when a difference between a signal strength of the source base station and a neighboring base station is equal to or greater than a predefined offset, calculating a delay value for delaying acknowledgement transmission corresponding to the segment received after detecting the delay condition event, and transmitting the segment received after the detection of the delay condition event by delaying by as much as a time corresponding to the delay value. The apparatus is capable of avoiding a router's performance degradation and reducing a packet transmission delay and packet loss.
