在WCDMA网络中，公共导频信道（CPICH）的功率电平对网络性能有很大的影响。导频信号的功率电平确定小区大小，从而确定小区的负载。通过考虑服务区域上业务强度的变化，可以调整导频功率以均衡小区上的业务负载。提出了WCDMA网络中的负载均衡模型，并提出了一种基于服务区全覆盖约束的负载均衡优化算法。我们报告我们的计算实验的现实生活中的WCDMA网络的柏林和里斯本。
In WCDMA networks, the power level of the common pilot channel (CPICH) has a significant impact on the network performance. The power level of a pilot signal determines the cell size, and thereby the load of the cell. By taking into account the variation of the traffic intensity over the service area, the pilot power can be adjusted to equalize the traffic load over the cells. We present a model for load balancing in WCDMA networks, and propose an algorithm for solving the load balancing optimization problem subject to the constraint of full coverage of the service area. We report our computational experiments for the real-life WCDMA networks of Berlin and Lisbon.
