Research on hierarchical service guarantee scheme for 5G network by Zhao SUN, Furong XU, Yantao HAN, Long ZHANG, Jinxia CHENG, Shanshan LIU, Wei DENG, Zhenping HU

“…The digital transformation process of economic society is accelerating.As the first of ＆quot;new infrastructure＆quot;, 5G will effectively enable the industry digital transformation.Facing the diverse needs of the industry in terms of network performance, operators need to provide the industry with hierarchical wireless service levels.Based on the analysis of 5G network performance requirements of industry services, the RAN-based service guarantee capability of 5G network was introduced from three aspects: data rate, delay and reliability.At the same time, based on the demands, various service guarantee technical technologies were combined and associated with network slice ID and 5QI to form a hierarchical service guarantee scheme.By matching industry service demands and network capacities, the integration and development of communication and vertical industry will be better promoted.…”

Key technologies and evolution of 5G non-terrestrial network by Deshan MIAO, Li CHAI, Jiancheng SUN, Ting KE, Yuzhen LIU, Xiaodong XU, Nan HU, Shanzhi CHEN

“…Non-terrestrial network (NTN) in 5G system is expected to provide communication services via near-earth space access and satellite access, which means 5G network has expanded its service area from land to space.Standardization status and key technolgies of 5G 3GPP Release 17 NTN were presented, including key differences compared 5G TN, especially in network architecture, time and frequency synchronization, HARQ, and mobility management etc.Moreover, the main candidate techniques in 3GPP Release 18 NTN and beyond were explored, aiming to outline a vision for NTN evolution.Based on the analysis of 5G NTN and its evolution, it was observed that the integration of TN and NTN would be an obvious technique trend, which paved a way to a unified system applied for space, land and sea.…”

Evolution scheme of 5G fusion user data architecture by Yuan ZHAO, Ziyu XIAO, Yan HAN, Hongyuan MA

“…User data management has experienced the evolution of 2G/3G and 4G era.At present,as a triple integration HLR/HSS service for mobile 2G/3G/4G/VoLTE users,contract data storage and authentication management,with the advent of 5G,5GC introduces cloud-based micro-service architecture UDM/UDR user data management network element,how to realize the evolution deployment of existing HSS and UDM,and how to realize the timely signing of 5G users to guarantee the 5GC business process urgently need to be studied.How to realize the evolution deployment of 5G user data to the four-fused HSS/UDM architecture based on the strategy of no-change card and no-change trademark commercial 5G market,and how to realize the smooth migration of 2G/4G user data to 5G user data at the same time was mainly researched.Finally,four HSS/UDM evolution schemes were presented and the rhythm of cloud migration was proposed.…”

Low latency handover scheme for 5G dual-connectivity scenario by Xuming PEI, Jianxin JIA, Hua QIAN, Zhenghang ZHU, Zhenyu TANG, Kai KANG

“…A novel handover scheme was proposed for the secondary node (SN) unchanged 5G dual-connectivity scenarios.In the proposed novel scheme,the SN connection was maintained for data packet transmission during the handover,however,both the main node (MN) and the SN were completely disconnected in the legacy scheme.The transmission delay during handover was decreased greatly by the proposed scheme.Firstly,the legacy handover scheme was analyzed and its deficiency was figured out.Then,the novel mechanism’s signaling interaction was elaborated and the time sequence models for the novel scheme and the legacy scheme were further established.Finally,based on the time sequence model,the performance evaluation processes were carried out in terms of mathematical modeling and experimental simulations.The analysis results demonstrate that the proposed novel scheme reduces the single packet transmission delay,the average transmission delay and the total transmission delay,and has good performance advantages.…”
