Abstract:	Resources such as Wideband Code Division Multiple Access (WCDMA) Orthogonal Variable Spreading Factor (OVSF) codes are considered scarce and valuable in modern cellular networks, therefore operators must use them efficiently. The author proposes an evaluation model for predicting OVSF single‐code allocation performance in WCDMA networks. In this paper, two performance measures‐call blocking probability (CBP) and bandwidth utilization (BU)‐are adopted to solve a utilization optimization problem. Specifically, a given traffic statistic and a specified maximum CBP constraint are applied to maximize BU in a Node‐B. Operators can use the results to deploy their codes flexibly and to improve profitability.
