Publication number: 20070280273Abstract: A method and apparatus to perform a handover of a mobile terminal that is receiving data, wherein before the handover is performed, the mobile terminal receiving data from a host provides information about a new network to the host by using a quick-start (QS) request message. Accordingly, the host recognizes that a packet loss caused by the handover is not caused by network congestion, and sets the size of a congestion window based on the information on the new network. Accordingly, waste of bandwidth can be reduced compared to that of a conventional slow-start algorithm.Type: ApplicationFiled: December 19, 2006Publication date: December 6, 2007Applicant: Samsung Electronics Co., Ltd.Inventors: Won-dong Yun, Young-Keun Kim
