stds-80220-requirements: 802.20 Requirements: Handoff Text
Attached is some text for the requirements document on handoff (802.20 to
802.20). These sections were deleted because there was no contributed
requirement in this area. This text probably belongs in section 4.4 since
it is in support of MAC-Level Handoff. I call it 4.4.2 below.
Rationale:
To support high speed mobility, handoff support below the IP layer is
essential to an efficiently operating air interface. For example, at 250
km/hr, assuming 1km cell radius as a nominal size, a mobile station could
be in handoff processing at rates up to several handoffs per minute. This
handoff rate will be difficult to support well at the IP layer, given IP
network delays, and the messaging overhead of current network layer
mobility solutions.
Proposed to include the following:
4.4.2 MAC Layer Handoff
The Air Interface shall include handoff support below the IP
layer. Handoff mechanisms defined shall insure the uninterrupted flow of
data to and from the Mobile Station at rates up to 6 handoffs per minute.
