Reaching a flat network is the main target of future evolved packet core for the 5G mobile networks. The current 4th generation core network is centralized architecture, including Serving Gateway and Packet-data-network Gateway; both act as mobility and IP anchors. However, this architecture suffers from non-optimal routing and intolerable latency due to many control messages. To overcome these challenges, we propose a partially distributed architecture for 5th generation networks, such that the control plane and data plane are fully decoupled. The proposed architecture is based on including a node Multi-session Gateway to merge the mobility and IP anchor gateway functionality. This work presented a control entity with the full implementation of the control plane to achieve an optimal flat network architecture. The impact of the proposed evolved packet Core structure in attachment, data delivery, and mobility procedures is validated through simulation. Several experiments were carried out by using NS-3 simulation to validate the results of the proposed architecture. The Numerical analysis is evaluated in terms of total transmission delay, inter and intra handover delay, queuing delay, and total attachment time. Simulation results show that the proposed architecture performance-enhanced end-to-end latency over the legacy architecture.
实现扁平化网络是 5G 移动网络未来演进分组核心的主要目标。当前的第 4 代核心网络采用集中式架构，包括服务网关和分组数据网络网关；两者都充当移动性和 IP 锚点。然而，由于存在许多控制消息，这种架构存在非最优路由和不可容忍的延迟等问题。为了克服这些挑战，我们为第 5 代网络提出了一种部分分布式架构，使得控制平面和数据平面完全解耦。所提出的架构基于包括一个多会话网关的节点，以合并移动性和 IP 锚点网关的功能。本工作提出了一个带有完整控制平面实现的控制实体，以实现最佳的扁平化网络架构。通过仿真验证了所提出的演进分组核心结构在附着、数据传输和移动性过程中的影响。使用 NS-3 仿真进行了多项实验，以验证所提出架构的结果。数值分析是根据总传输延迟、内外切换延迟、排队延迟和总附着时间来评估的。仿真结果表明，所提出的架构在端到端延迟方面优于传统架构，从而提高了性能。
