5G network not only serves individual users, but also meets the digital transformation needs of industries. The increasingly diversified 2B plus 2C services have further deepened the contradiction between “one-fit-all” network policy and differentiated user experience requirements. ZTE innovatively proposed the industry’s first intelligent orchestration of radio resource solution Radio Composer,
Starting from multi-layer of whole network, Radio Composer leverages an intelligent orchestration engine to enable multi-dimensional perception and machine learning of UE capability, service and network characteristic, and inter-domain information, manages and optimizes radio resources to meet service requirements in a dynamic way. The solution takes the lead to use BBU native AI capability as the key driver of wireless network intelligence, together with advanced radio resource allocation algorithm to empower consumers and industry applications with first-class like performance without the necessity of extra hardware, enables network policy shifting from“one-size-fit-all”to“context-aware“. The AI training and inference is implemented when CPU working at low load in order to minimize impact on legacy user experience, and the computing capability coordination is at inter-site scenario according to the mobility of 5G users. The BBU native AI capability enables edge computing, which makes service application as close to access as possible. Radio Composer features flexible radio resource scheduling via network orchestration and user orchestration.
Network orchestration targets at a future-oriented network design, enables spectrum, frame structure and beam pattern orchestration according to intelligent traffic prediction and interference avoidance on a cluster basis, implements accurate mapping between variable network serving capabilities and prediction of traffic pattern to improve network payload and reduce O&M cost. According to field test result, it increases network payload by 32% on average and reduces O&M cost by 46%.
User orchestration targets at smooth user experience with user steering and user scheduling. The orchestration is based on accurate predictions of network service capabilities and precise recognition of service requirement, combined with terminal capabilities to achieve flexible steering and scheduling among multiple frequencies in the network. In field network, user orchestration improves cell-edge user average throughput by more than 300%, reduces handover delay by more than 48% and decreases low-speed NR user ratio by 51%.
In addition, Radio Composer can be driven by more intentions, such as energy-saving intentions for carbon neutrality and the comprehensive integration of multiple intentions, like experience, efficiency and energy efficiency. With the introduction of cross-domain information, the joint orchestration of 2B and 2C will be further strengthened to implement much flexible coordination of user experience, network efficiency and other intentions within a single network, so as to facilitate society digital transformation with 5G and boost 5G bushiness success.
