DATA PATH TRANSFER FOR MULTIBAND COMMUNICATION

摘要

Data path transfer is set up between concurrently operating frequency bands of multiband WLAN devices. The Fast Session Transfer (FST) is enhanced by introducing a new Information Element (IE) in the FST frames to enable negotiating the parameters to be established as a result of switching of a portion of the existing data/traffic streams to another frequency band. The new IE includes the number of streams being switched and for each stream being switched the stream ID. The new IE enables wireless transmitting and receiving devices to negotiate connection setup parameters associated with a requested transfer of the operating frequency band. Transmitting device sends an FST Setup Request frame with the new IE that includes the requested number of streams being switched and for each requested stream being switched the ID. Receiving device replies with an FST Setup Response frame accepting the parameters or with an alternate number of streams.
