accessed”, Column 8, lines 3-5. Thus in Adaptive-Dynamic Channel Assignment,
the non-regular channel allocation is used until there are
no longer any channels available, then additional channels are allocated.
Benveniste teaches that Adaptive-Dynamic Channel Assignment is accomplished
using three logic functions, channel acquisition (channel borrowing), channel
release and channel (re)allocation, (the non-regular channel allocation) Column
9, lines 24-30. Benveniste teaches a preferred method to perform (re)allocation
of channels and also states “the ADCA [Adaptive- Dynamic Channel Assignment]
Algorithm described herein can be used with other channel allocation
methodologies.” Column 11, lines 46-47. We feel that this passage would
provide suggestion to one of ordinary skill in the art to look to other methods of
non-regular channel allocations such as Yu’s channel allocation which addresses
“real world” limitations on channel assignment.
Appellant argues, on pages 9 and 10 of the brief, that Benveniste teaches
allocation of channels among cells within a wireless system and not among
sectors in a single cell.
We are not convinced by this argument as we find that Benveniste
implicitly teaches that channels are transferred between sectors in a cell. As the
examiner points out on page 12 of the answer, Benveniste, recognizes that some
cells are sectorized into smaller angular areas, see column 3, lines 12-19.
