摘要:

5G无线接入网络是一种复杂的异构网络,各个协议之间的封闭性限制了网络性能。为了统一管理异构网络,向用户提供个性化的服务,提出了一种基于软件定义的以用户为中心的新型网络架构。该架构通过软件定义的形式统一管理所有无线网络,打破了传统蜂窝小区的概念,针对每个用户生成以用户为中心的小区,小区内的所有基站都能为该用户提供服务。这种新的网络架构能够为用户提供个性化的网络服务,提升用户的峰值速率和边缘用户性能。

关键词: 5G, 软件定义无线网络, 以用户为中心的小区

Abstract:

The radio access network of 5G is a complex heterogeneous network.The independence of different protocols limits the network performance. To unify the management of the heterogeneous network and provide personalized service,a software defined user centric framework was provided. Such framework unifies the management of the heterogeneous network by the idea of software define,and it breaks the concept of traditional ce11.The user centric cell is formulated for each user to provide better service and all the base stations in the cell can serve this user. This framework provides personalized service for each user and improves the peak rate as well as the cell edge rate.

Key words: 5G, software defined wireless network, user centric ce11
