Abstract

Roaming performance of a mobile client exchanging data with a current access point (AP) is enhanced by discovering candidate APs available for roaming, combining information from the candidate APs to construct an aggregated fast transition (FT) request frame, and sending the aggregated FT request frame to an aggregated FT handler, which sends individual FT request messages to each candidate AP, receives individual FT response messages from each candidate AP, combines the individual FT response messages to construct an aggregated FT response frame, and sends the aggregated FT response frame to the client. The client selects a target AP from the candidate APs, constructs a reassociation request frame based on the aggregated FT response frame, sends the reassociation request frame to the target AP, receives a reassociation response frame constructed by the target AP based on the aggregated FT request and response frames, and exchanges data with the target AP.
