摘要
5G网络对传送网提出了大带宽、低时延、高可靠性、高精度时间同步、灵活组网、网络切片和智能协同管控的新需求,同时面临无线接入网和核心网组网架构的演变,给传送网带来了新的挑战。通过对5G的3大应用场景需求分析,结合5G无线接入网、核心网组网的架构,给出了无线接入网前传、中传以及回传的解决方案,探讨了5G高效承载的传送网关键技术。通过5G传送网组网方案和关键技术的研究、探讨,对运营商企业5G传送网的建设提供参考建议。
The 5G network brings forward new requirements of large bandwidth, low latency, high reliability, high-precision time synchronization, flexible networking, and network slicing and intelligent coordinated management for transport network. At the same time, the evolution of wireless access network and core network networking architecture brings new challenges to the transport network. Based on the requirements analysis of the 5G application scenarios and by combining the architectures of 5G wireless access network and core network, the solutions for the pre-transmission, intermediate transmission and backhaul of the wireless access network are given, and the key technologies of 5G efficient bearer transmission network also discussed. The research and discussion on 5G transport network networking scheme and key technologies may provide reference suggestions for the construction of 5G transport network for operators.
