Prospect of 6G global convergence network

【 pick   want 】 In order to pass on 6G Prospect of global convergence network , explain 6G Basic research direction , First introduced 6G Our network vision , extraction 6G The concept of global convergence network ; Then analyze 6G Network characteristics of global convergence network ; And based on 5G And 5G-advanced Related research , From the perspective of evolution , From access 、 control 、 Cloud collaboration describes the potential technical direction and trend in three aspects . The comparative study shows , Existing based 5G Basic research of network , Have been gradually considering to 6G The evolution needs of the global convergence network .

0    introduction

Mobile communication is now at a positive time 5G The opportunity for the vigorous development of the network , Compared with the past 3G、4G Network of ,5G The network has greatly expanded its service audience , government administration versus business enterprise 、 The industry will be the main service provider , The diversity of its needs 、 The demand of network customization and application deep integration tests the ability and deployment form of the network , Driving the communication network to high performance 、 flexible 、 intelligence 、 The direction of security evolves .6G Network as the next generation communication network , Driven by new demands and new technologies , The goal is to build a global integrated network with diversified interconnection of all things , Such a network must have super performance 、 Ubiquitous connection 、 Intelligent endogenesis 、 Safe and trustworthy 、 Network features such as flexible self-healing . Industry pairs 6G There are similar views on the basic characteristics of the network , For example, China Mobile in 2019 Published in 《2030+ Vision and needs report 》 It is proposed that the future network will have five characteristics ： On demand service network 、 Zhijian network 、 Flexible network 、 Wisdom is endogenous and safety is endogenous [9]; China Unicom in 2021 First released 《 The white paper of China Unicom 》 in “ intelligence 、 The fusion 、 green 、 trusted ” Eight words to summarize its future 6G Preliminary vision [8]. Whether it is clearly stated or not , All network features are based on the connection of all things . and 6G Global convergence network , In broad sense , It's the next generation 6G The pronoun of the Internet , Have the above comprehensive network characteristics , It is a combination of cross domain technology and multimodal Networks ; Narrowly ࿰
