摘要

3GPP 5G网络架构在3GPP Rel-16版本定义了无线有线融合架构，即固移融合网络架构，并重点研究此融合架构下的多个价值场景。其中，有线与无线混合接入场景备受关注，同时 3GPP 标准定义了此场景下的多接入流量调度机制。对此进行了详细论述，包括基本的多接入流量调度机制、增强5G-Adanced网络支持UDP业务流和以太业务流的包粒度分流机制以及新的冗余传输模式，并扩展4G和5G互通场景以支持3GPP接入5GC和非3GPP接入EPC的混合网络流量调度。

Abstract

In 3GPP Rel-16

3GPP 5G network architecture defines the wireless and wired converged architecture

that is

fixed and mobile converged network architecture

focusing on multiple valuable scenarios of this converged architecture

where the wired and wireless hybrid access scenario attracts much attention.The standard defines the multi-access traffic scheduling mechanism in this scenario.It was discussed in detail

including basic multi-access traffic scheduling mechanisms

enhanced the traffic splitting per packet mechanisms for UDP and Ethernet traffic flows for 5G-Advanced networks

and a new redundant transmission modes.In addition

4G and 5G interworking scenarios were extended to support hybrid network traffic scheduling for 3GPP access to 5GC and non-3GPP access to EPC.
