摘要：

5G 网络演进过程中组网模式的改变导致 SPN 面临着泛在覆盖的局限性，进而导致集客专线客户接入距离远。基于运营商面向效益的建设思路，解决SPN覆盖进一步深化的过程中面临的网络效益问题。以典型配置的经验价值成本为例，针对不同场景提出 3 种下沉部署策略。搭建仿真环境，采用高斯混合模型模拟集团客户点位分布特征，并分析稀疏、普通、密集场景下的总客户数、下沉SPN设备数与客户覆盖率之间的关系，测试不同下沉策略的网络效益。由仿真结果可知，策略3在总客户数为600时，仅面向下沉效益高的区域覆盖，最大覆盖率只能达到55.27%，但随着客户点数增多，策略3最大覆盖率可达到82.71%，具有明显的覆盖优势，同时平均下沉设备可覆盖客户数最多，实现了保障高效益条件下的高覆盖能力。

Abstract:

With the change of networking mode in the evolution of 5G network, SPN is faced with the limitations of ubiquitous coverage, which leads to the long access distance of the passenger dedicated line customers.Based on the operator's benefit-oriented construction idea, in order to solve the network benefit problem in the process of further deepening SPN coverage.Three sink deployment strategies were proposed for different scenarios, taking the empirical value cost of typical configurations as an example.By building a simulation environment, Gaussian mixture model was used to simulate the distribution characteristics of group customers, and the relationship between the total number of customers, the number of sinking SPN devices and customer coverage in sparse, common and dense scenarios were analyzed, and the network benefits of different sinking strategies were tested.The simulation results show that strategy 3 only faces the area coverage with high sinking efficiency when the total number of customers is 600, and the maximum coverage rate can only reach 55.27%.However, with the increase of customer points, the maximum coverage rate of strategy 3 can reach 82.71%, which has obvious coverage advantages.At the same time, the average number of sunk equipment can cover the highest number of customers, realizing the high coverage ability under the condition of ensuring high efficiency.

Key words: SPN sinking deployment, service access, group customers dedicated line, network benefit
