Appeal No. 2001-2052
Application No. 08/943,427
Appellant's invention relates to a method for minimizing transmitter power levels
within a cellular telephone communications network. An understanding of the invention
can be derived from a reading of exemplary claim 1, which is reproduced below.
1. A method for maintaining optimal transmitter power levels within a
cellular communications network, wherein said cellular communications
network includes a plurality of cellular base stations and a plurality of
cellular telephones, said method comprising the steps of:
periodically performing a carrier-to-interference ratio measurement
between a first cellular base station and a cellular telephone;
in response to a determination that said measured carrier-to-
interference ratio is higher than a carrier-to-interference ratio upper
bound, reducing an optimal transmitter power at said cellular base station
by one step;
in response to a determination that said measured carrier-to-
interference ratio is lower than said first carrier-to-interference ratio upper
bound, determining whether or not said measured carrier-to-interference
ratio is lower than a carrier-to-interference ratio lower bound;
maintaining said optimal transmitter power at said first cellular base
station if said measured carrier-to-interference ratio is between said
carrier-to-interference ratio lower bound and said carrier-to-interference
ratio upper bound; and
handing off said cellular telephone to a different channel within a
same cell when said measured carrier-to-interference ratio is lower than
said carrier-to-interference ratio lower bound.
The prior art of record relied upon by the examiner in rejecting the appealed
claims are as follows:
