Appeal No. 2000-1459
Application No. 08/703,907
Moritz is concerned with a “simulating” positions of cells
with respect to the earth. By calculating cell positions,
based on orbit position, satellite speed, orbits’ distance
from the earth and angles of displacement for various beams
supported by the satellites’ antennas away from the
satellites’ Nadir directions, Moritz determines the location
of the center of each cell and assigns active or inactive
status to the cells. Overlaps are declared based on distances
between two cells. The cell position simulation and
assignment process is repeated numerous times to determine
when particular cells go active and inactive. This improves
scheduled handoffs in cellular communications since Moritz can
anticipate, or forecast, when movement of the cells will cause
a subscriber unit to cross cell boundaries.
We find nothing in the cited portion of Moritz, column 5
to column 6, that suggests anything about a position-beam
correspondence table, as claimed. With regard to the
scheduler of Moritz, cited by the examiner, as pointed out by
appellant in the reply brief, it is clear that schedule 800 in
Figure 8 of Moritz stores a channel/cell list indexed against
time, not position. Also, Moritz discloses a process for
