Network Optimization Process
Ø
Single site verification
Single site verification, the first phase
of network optimization, involves function verification at each new site.
Single site verification aims to ensure that each site is properly installed
and that parameters are correctly configured.
Ø
RF optimization
RF (or Cluster) optimization starts after all
sites in a planned area are installed and verified. RF optimization aims to
control pilot pollution while optimizing signal coverage, increase handover
success rates, and ensure normal distribution of radio signals before parameter
optimization. RF optimization involves optimization and adjustment of antenna
system hardware and neighbor lists. The first RF optimization test must
traverse all cells in an area to rectify hardware faults.

distribution, site information, and engineering parameters.
·
Drive test result (such as service drop
points and handover failure point) in the current area.

·
Measured handover success rates
Ø Areas
to be optimized can be determined by comparing the distribution of RSRPs,
SINRs, and handover success rates with the optimization baseline.
