July. 2003 doc. : 802_Handoff_Problem_Statements Problem Statement #1 • Detection of Network Attachment (DNA) is impacted by the ambiguous indicators of network attachment in certain 802 MACs. Thus there is a need to develop a standard that allows a mobile terminal to optimize detection of network attachment (DNA) above the LLC. – Based on ‘DNAv 4 and Handoff Scope’ presentation by Bernard Aboba Submission 2 David Johnston, Intel

July. 2003 doc. : 802_Handoff_Problem_Statements Motion #1 • The 802 Handoff Executive Committee Study Group recommends problem statement #1 as a finding of the group. “Detection of Network Attachment (DNA) is impacted by the ambiguous indicators of network attachment in certain 802 MACs. Thus there is a need to develop a handoff standard that allows a mobile terminal to optimize detection of network attachment (DNA) above the LLC” Submission 3 David Johnston, Intel

July. 2003 doc. : 802_Handoff_Problem_Statements Problem Statement #2 • The length of interruption of service during a higher layer (above the LLC) handoff between 802 networks is sub optimal in part because the 802 networks provide insufficient information to the upper layers to achieve optimality. Thus there is a need to develop a standard that permits a mobile terminal to switch between one point of attachment and another with minimal latency. – Based on ‘DNAv 4 and Handoff Scope’ presentation by Bernard Aboba Submission 4 David Johnston, Intel

July. 2003 doc. : 802_Handoff_Problem_Statements Problem Statement #3 • There is no standardized way in 802 for a mobile terminal to acquire information on which to base decisions to select between disparate network attachment points or to initiate handoffs between heterogeneous network type or between administrative domains within a single network type. Thus there is a need to develop a standard that permits a mobile terminal to access information from a network attachment point on which to base good and timely handoff decisions. – Based on Presentation ‘ 802 Handoff Architecture Elements r 2’ by David Johnston Submission 6 David Johnston, Intel
