With the arrival of 5G era, the telecom network gradually evolves from legacy network to virtualized network. Under such circumstances, the network architecture of operators becomes more open, the resources sharing becomes more flexible, and the service innovation becomes faster and more agile. Meanwhile, as the standard 5G CN architecture comprises several NEs, the networking is complex, and the hardware & software decoupling degree is greater along with the virtualization evolution. All these bring huge challenges, in network planning & design, verification, deployment and test from vendors and cross-region integration for the operators.
