Partner Perspectives Huawei 3/1/2021 The development of 5G networks began to greatly accelerate in 2020. At the 11th Global Mobile Broadband Forum (MBBF) in Shanghai in 2020, Huawei launched "1+N" 5G target networks. In order to embrace the approaching golden decade of 5G, full spectrum evolution and the construction of one high-bandwidth simplified target network capable of ensuring ubiquitous connectivity with on-demand overlay of 'N' capabilities is required. However, many challenges await on the path to "1+N" target network evolution. One such challenge involves effectively deploying BtoB capabilities and maintaining 2G, 3G, 4G, and 5G simultaneously. Evolving towards Autonomous Driving Network (ADN) is one of the best ways to cope with the increasing complexity of mobile network. A network architecture featuring layered autonomy and vertical collaboration and scenario based OPENNESS is required for the 1+N mobile network moving forwards the intelligent autonomous network.
