摘要
文中利用剩余容量的概念,提出了CDMA系统中基于多业务的软切换优化算法,并对其进行了仿真。此算法综合考虑了传播衰耗和负载均衡两个因素,达到了各小区之间负载平衡和资源合理利用的目的。通过仿真结果可以看出,相对于传统的软切换算法,新算法降低了切换中断率,提高了系统性能,显示出较大的优越性,具有一定的价值。
This paper, by using the concept of residual capacity, proposes an optimized soft handoff algorithm for multi-traffic CDMA systems. Attenuation of dissemination and load balance are both considered in order to achieve the goal of load balance between cells. The simulation results indicate that, compared to traditional soft handoff algorithm, the novel algorithm reduces the handoff termination probability and raises the system performance.
