中文摘要：

为了减少移动核心网的信令链路负荷，提高资源利用率，提出了一种核心网的组网方案。通过MSC POOL组网实现该方案，并对接入到MSC POOL核心网中的随机移动用户建立概率模型，利用泊松概率分布模型对MSC POOL网络进行理论定性分析和实验。实验结果表明，与传统组网相比，该方案降低了网络负载率，提高了切换成功率和位置更新成功率，对于移动网络结构和性能有着整体的提升。

英文摘要：

In order to reduce the load on signaling links of mobile communication core networks and improve resource utilization, a novel networking scheme of core networks is proposed in this paper. Implemented by means of MSC POOL networking, the scheme establishes a mathematical model with random access mobile user in MSC POOL based core networks, qualitatively analyzes and conducts experiments on MSC POOL based core networks using Poisson distribution model. Experimental results demonstrate that, compared with traditional networking schemes, the proposed scheme not only reduces the network load rate, but improves both handover success rate and location update success rate as well. Thus, mobile network structure and the overall performances have been enhanced.
