The new 5G use cases including enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC) require the implementation of a service-based architecture (SBA). The service-based architecture emphasizes services as the primary architecture component used to put in place and execute functions. The particular network service could be provided by single or multiple network functions in the core network.
The transition to SBA separates the end-user service from the underlying network, making for a more agile network. The SBA also borrows many aspects from software-defined network technologies. For a true SBA, NF services must be self-contained and reusable. NF services should also use management schemes autonomously, separate from other services offered by the same NF. This new environment pushes companies to design cloud-native 5GC functions or containerized network functions.
Understanding of this architecture can help network planners, developers, system integrators create blueprints for the next generation telecom networks that could support new and diverse use cases. Download to know more.
