A system and method collects radio frequency isolation values with the
assistance of mobile stations operating within a cellular wireless
communication system. A broadcast channel and a broadcast cell/sector are
first chosen. Then, the broadcast channel is disabled in neighboring (or
all) other cells/sectors in the system. The base station servicing the
broadcast cell/sector then transmits on the broadcast cell sector. Mobile
stations operating within the system are then directed to measure and
report the signal strength of the broadcast channel as well as a traffic
channel servicing their ongoing calls. The mobile stations then report
these signal strengths to the cellular wireless communication system. The
signal strength measurements are then used to calculate cell/sector radio
frequency isolation values between the broadcast cell/sector and
respective servicing cell/sectors. Because the broadcast channel may be
transmitted at a greater level than normal transmissions, a normalization
process may be required. This process is then repeated for each
cell/sector in the system so that cell/sector radio frequency isolation
values may be collected for these other cells/sectors. Finally, all
collected cell/sector isolation values are processed and complied to
create an isolation matrix.
