“…From the simulations, it became clear that there is a tradeoff between blocking and dropping by adjusting thr CAC (cf. also [12]). A more restrictive threshold setting (e.g., thr CAC ϭ 50%) lowers the dropping probability P drop while the blocking probability P block increases.…”

“…Gains with multicell admission control were also found in Reference [4]. Study in Reference [33] suggested that the uplink interference target is set as a trade-off between blocking and dropping. Similar ideas were suggested in studies in References [4] and [24], which defined call dropping ten times more costly than blocking.…”

SummaryThis paper validates the feasibility of automated optimization of key wideband code division multiple access (WCDMA) radio resource management parameters using control methods. The parameters are regularly adjusted in order to improve performance. The parameters examined in this study include the total cell transmission power target, the received total interference target, the downlink radio link power maximums, the handover windows and the pilot channel powers. The control was based on expert-defined rules, which applied specific trade-off policies and statistics of poor quality calls, blocking, packet queuing, power and interference levels and terminal measurements to qualify the parameter values. The approach was validated using a dynamic WCDMA system simulator with a deployment of macro and micro cells on a city region. Results on automated optimization of single parameters on cell level and results on simultaneous multi-parameter optimization on cell-cluster level are presented in this paper. The use of the automated parameter optimization methods was shown to result in a significant increase of capacity in comparison to the default parameter settings.
