AI总结:

针对现有5GS控制面缺乏切片隔离等问题,提出一种5G后网络控制面切片架构,提升模块化、可扩展性与隔离性,并通过评估验证其性能优势。

摘要:

为了容纳具有不同特征的各类用例,第五代(5G)移动通信系统计划采用网络切片。网络切片支持在共享的物理网络基础设施之上创建多个逻辑网络。尽管现有文献已相当详细地探讨了移动网络中多切片资源分配等问题,但现有移动网络架构对网络切片的适配性尚未得到充分分析。我们认为,现有5G系统(5GS)架构存在若干局限,例如其控制面缺乏切片隔离。本研究从切片视角,尤其是控制面切片视角,关注现有5GS架构的未来演进,以解决其部分局限。我们提出了一种新的网络架构,可在5G后网络中实现高效切片。所提架构提升了支持切片的移动网络中控制面的模块化与可扩展性。此外,它还为控制面带来了切片隔离,而这在现有5G系统中无法实现。我们还给出了性能评估,结果证实所提系统相较现有5G系统具有更优的性能和可扩展性。

英文摘要:

To accommodate various use cases with differing characteristics, the Fifth Generation (5G) mobile communications system intends to utilize network slicing. Network slicing enables the creation of multiple logical networks over a shared physical network infrastructure. While the problems such as resource allocation for multiple slices in mobile networks have been explored in considerable detail in the existing literature, the suitability of the existing mobile network architecture to support network slicing has not been analysed adequately. We think the existing 5G System (5GS) architecture suffers from certain limitations, such as a lack of slice isolation in its control plane. This work focuses on the future evolution of the existing 5GS architecture from a slicing perspective, especially that of its control plane, addressing some of the limitations of the existing 5GS architecture. We propose a new network architecture which enables efficient slicing in beyond 5G networks. The proposed architecture results in enhanced modularity and scalability of the control plane in sliced mobile networks. In addition, it also brings slice isolation to the control plane, which is not feasible in the existing 5G system. We also present a performance evaluation that confirms the improved performance and scalability of the proposed system viz a viz the existing 5G system.
