摘要
为解决CDMA(CodeDivisionMultipleAccess)网络中综合业务的协调传输问题,提出了资源竞争模型。以非实时类业务和实时类业务为对象进行了考察,在考虑业务群体的Logistic变化规律的基础上,推导出竞争平衡方程,给出了平衡点的获取过程,进一步分析了模型的稳定性。实验表明,平衡方程的应用可以限制两类业务的优先级,获得了较好的系统容量;同时非实时类业务的阻塞率在业务量增大的时候明显高于实时类业务,提高了系统的整体性能。
A competing resource model is given in order to solve the problem how to harmonize the integrated admission over CDMA network. The research is done between real time admission and unreal time admission,based on the admission's Logistic changing rule it deduces a competing balance equation. It gives the computing process of the balance point value and analysis about stability to the model. The experiment result shows that the application of the balance equation could restrict the priority of two kinds of admission, gain better system capability additionally. It improves the system feature that the block rate of unreal time admission is higher than real time admission while admission is busy.
