Problem Statement• Statement 1: There is a need to develop a handoff standard that allows a
mobile terminal to change its point of attachment from one 802-network of some type to another 802 network of a different type, and from an 802 network to a non-802 network (e.g., GPRS) and vice versa.
• Statement 2: There is a need to develop a handoff standard that allows a
mobile terminal to change its point of attachment from one 802 network of some type to another 802 network of the same or a different type, or to a non-802 network (and vice versa), without interrupting data delivery to/from that terminal.

Scope Statement (1a)• Statement 1: To develop a PHY/MAC layer standard that specifies a
common framework for handoff between two 802 networks of the same or different types, or between an 802 network and a non-802 network.
– Characterization A:
The framework shall specify handoff primitives and procedures that can be realized in 802 networks of most (if not all) types and selected non-802 networks.• Examples of primitive: probe (discovery of candidate target point of
attachment), authenticate, associate, create forwarding tunnel, etc.
• Procedures: sequences of primitives
• Selected non-802 networks: include at least GPRS (Release 5 and later)

Scope Statement (1b)• Statement 1: To develop a PHY/MAC layer standard that specifies a
common framework for handoff between two 802 networks of the same or different types, or between an 802 network and a non-802 network.
– Characterization B: The framework shall make handoffs seamless under favorable conditions
to be specified.• Smooth: lossless (don’t lose packets due to HO)
• Fast: low delay
• Seamless: smooth and fast
• Examples of favorable condition: (1) mobile terminals can maintain simultaneous connectivity with multiple points of attachment; (2) the source point of attachment can forward packets to the target point of attachment; (3) others

Scope Statement (1c)
• Statement 1: To develop a PHY/MAC layer standard that specifies a
common framework for handoff between two 802 networks of the same or different types, or between an 802 network and a non-802 network.– Characterization C: The framework shall not address mechanisms for handoff in Layer
3 or above, billing/accounting, and authentication.• The framework will use authentication mechanisms developed by
802.1X

Scope Statement (2)
• Statement 2: To develop a standard that specifies a common
framework for 802 triggers to be used by Layer 3 for handoff.– Characterization 1: The framework shall specify abstract trigger types, to
be specified by IETF or jointly specified by IEEE and IETF, that can be realized in 802-networks of most (if not all) types and selected non-802 networks.
