  1. Proposed Problem and ScopeStatements for Handoff ECSG Huai-An (Paul) Lin Intel Corp. May 2003 Paul Lin, Intel Corp

  2. 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 toa non-802 network (and vice versa), without interrupting data delivery to/from that terminal. Paul Lin, Intel Corp

  3. 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) Paul Lin, Intel Corp

  4. 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 Paul Lin, Intel Corp

  5. 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 Paul Lin, Intel Corp

  6. 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. Paul Lin, Intel Corp

  7. Motion • To straw poll on the proposed problem statements and scope/characterization statements • - Problem Statement 1 • - Problem Statement 2 • - Scope Statement 1/Characterization 1 • - Scope Statement 1/Characterization 2 • - Scope Statement 1/Characterization 3 • - Scope Statement 2/Characterization 1 Paul Lin, Intel Corp
