MWC 2018: China Mobile and Huawei Demonstrate Microservice-based 5G Core Network
At the Mobile World Congress, China Mobile, together with Huawei, demonstrated the world's first microservice-based 5G core network constructed on top of service-based architecture. The demonstration is a follow-up of their joint release of an SBA-based 5G core network prototype at 2017 MWC Shanghai.
Huawei believes the 5G core network software architecture needs to be further broken down into microservices under 3GPP-compliant SBA architecture to achieve 5G standalone networking. This fully exploits the structural advantages of service-based network functions, interfaces, and operation.
Based on the concept of "slice-as-a-service", microservices are designed on demand and can then be flexibly deployed. Scaling and upgrades can be performed independently for each microservice. This leads to agile design, deployment and operation of microservice-based 5G core network.
This successful demonstration unveils a service-based interface that complies with HTTP2.0 protocol, and microservice lifecycle management. In addition, based on containers, it implements dynamic loading of third-party apps and service switching. It also shows operation-oriented slice instantiation and management.
