Three Colliding Trends

• Industry evolving from portable computing to mobile computing

• Applications starting to demand seamless connectivity (VoIP)

• More state necessary to set up during association before data communications allowed (QoS, Security)

Problem Statement

• Develop a standard to allow fast roaming in a general way that will allow seamless connectivity during a roam that can be extended for future negotiation requirements

Possible Solutions 1

• Make before break (associate with new AP before dropping association from old AP)

• Pre-association negotiation (allow handshaking and negotiation before Associate Request/Associate Response)

Problem: APs will probably be on different channels

Possible Solutions 2

• State handoff between APs using IAPP (push or pull model)

Possible Overlaps 1

• IEEE P802 Handoff Study Groupintends to develop a roaming solution at the 802 level, more specifically for multi-interfaces devices needing to handoff between interfaces where no procedures for handing off exist, and for handoff within a technology type (say 802.11) but between networks and administrative domains where handoff is not supported within the base standards (e.g. inter-ESS handoff in 802.11). The IEEE P802 Handoff Study Group does not address the more specific issue of fast roaming within an ESS, which this project will address.

Possible Overlaps 2

• IEEE 802.11 TGfRecommended practice, not a standard, and that Task Group is done.

Possible Overlaps 3

• IEEE 802.11 TGiNeed a more general purpose mechanism, one that can help QoS and any future needs.
