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.
ZTE 5GC automatic integration solution solidifies and integrates the integration procedure through AIC (Auto Integration Center). It provides customized integration design in real time as required by the customer and verifies the design feasibility. After the verification, it generates detailed design documentation for 5GC network integration automatically, which is imported into the integration deployment tool on site for E2E silent integration deployment and automatic verification through the procedure. In this way, it realizes "zero intervention" in the integration deployment by users on 5GC site and shortens 5GC deployment/verification time greatly. In the integration procedure life-cycle, from integration planning & design, network deployment to integration test E2E, it realizes "zero distance" between the integration design and the customer's requirements, effectively relieving the operators from their pain points about 5G network integration. In addition, ZTE 5GC automatic integration solution introduces cloud experience model by taking the support of offline design and remote deployment into consideration, enabling users to directly execute 5GC network integration planning and pre-integration verification in real time on the cloud, and making the selection and deployment from application scenario to NEs more convenient and flexible.
Highlights of plan & customer value
ZTE 5GC automatic integration solution provides a series of E2E and one-stop services, covering 5GC network integration planning & design, plan verification, test design, integration deployment and integration test, for the operators through AIC. The OpenLab and pre-integration work flow cover various 5GC NFV integration full-service scenarios, such as NFVI integration, MANO integration and VNF integration, which make 5GC scenario integration much easier, accelerate 5G network construction for the operators and facilitate the network transformation.
As verified by ZTE projects, 5GC automatic integration solution enhances the entire integration deployment efficiency by more than 65%:
Up to now, ZTE 5G CN solution has been applied in 5G pilot and commercial networks of operators from India, Japan, Austria and so on as well as the three operators in China. Besides, the solution has been demonstrated in Europe 5G forum and global users conference held in November 2018 and in China Mobile Global Partner Conference held in December, widely recognized by the operators in China and from abroad. In the annual ICT champion list selection introduced by telecom omnimedia, the solution won "2018 SDN/NFV Best Practice Award".
