摘要: 2019年6月6日工信部向中国电信等4家运营商发放5G牌照,意味着中国已步入5G商用元年。5G可以说是新一轮颠覆性的信息技术革命,其具备高速率、大容量、低时延的特点,因此对5G前传网络提出了更高的技术要求。为此,基于5G业务和架构新特性、5G承载需求特性等综合分析,提出4种前传承载解决方案,并给出不同场景下的5G前传承载方案建议。

Abstract: The Ministry of Industy and Information Technology granted 5G licenses to relevant operators on June 6,2019, marking China′s entry into the first year of 5G commercialization. 5G is set to be a new round of disruptive revolution in information technology, with significant advantages including high speed, large capacity, and low delay. So it also puts forward some stringent technical requirements such as high bandwidth and low delay for 5G fronthaul network. Therefore,based on the comprehensive analysis of 5G new features of business and architecture, 5G carrying demand characteristics, etc., this paper proposes four kinds of prequel carrying solutions, analyzes their advantages and disadvantages and application scenarios, and summarizes suggestions on 5G fronthaul transmission solutions applicable to different scenarios.
