TECHNIQUES FOR LOSSLESS PACKET TRANSITION ACROSS BASIC SERVICE SETS IN WIRELESS NETWORKS

摘要

An embodiment of the present invention provides a system, comprising a wireless station (STA), a first access point (AP1) operable to communicate with the wireless station, a second access point (AP2) operable to communicate with the wireless station, and wherein the STA is adapted to transition wireless communications from the first access point (AP1) to the second access point (AP2) using a Post-Transition Extended Session and a Post-Transition Extended Session Aliveness Interval to allow the STA and AP1 to keep an old session alive for the duration of the Post-Transition Extended Session Aliveness Interval and during the Post-transition Extended Session, the STA can come back to the AP1 and recover all the leftover packets.
