摘　　要：随着卫星互联网时代的到来,传统卫星通信运营商面临服务模式单一化与用户场景多元化不相匹配的矛盾。针对多场景应用需求下服务质量保障不足的突出问题,提出卫星通信差异化网络切片服务解决方案。参照5G移动通信网针对增强型移动宽带(eMBB)、超高可靠超低时延通信(uRLLC)、海量机器类通信(mMTC)三大应用场景的网络切片解决方案,梳理了5个卫星通信典型应用场景,提出了利用网络功能虚拟化(NFV)、网络切片技术构建卫星通信网络切片服务,满足多场景典型应用的技术方案构想,对卫星通信网络架构、网络切片要素、网络切片编排进行了详细描述。通过网络切片编排模型仿真,验证了卫星通信网络按需重组构建多类逻辑网络,以及对多场景应用的支持能力。在当前卫星通信资源极大丰富的条件下,可为后续扩展多场景卫星通信业务,建立良好的应用生态提供参考。In the era of satellite Internet,constrained by the single-service model of traditional satellite communication operators,it is difficult to ensure the quality of service when facing users’multi-scenario application needs.Referring to the network slicing solutions of 5G mobile communication network for three key application scenarios(eMBB,uRLLC,and mMTC),this paper analyzes five typical application scenarios of satellite communication,proposes a technical concept of building satellite communication network slicing services using network function virtualization and network slicing technology to address the needs of multi-scenario applications,and describe the satellite communication network architecture,network slicing elements,and network slicing configuration.In the context of abundant satellite communication resources,it can offer a reference for expanding multi-scenario satellite communication services and establishing a good application ecosystem in the future.
