5G RAN Architecture 3GPP:
5G RAN Architecture and concepts:
The 5G RAN architecture is described to guide facts connectivity and offerings enabling deployments to use techniques such as e.g. Network Function Virtualization and Software Defined Networking. The 5G RAN Architecture shall leverage service-based totally interactions among Control Plane (CP) Network Functions wherein identified. Some key concepts and idea are to:
· Separate the (UP) functions from the (CP) functions, allowing independent scalability, evolution and flexible deployments e.g. Centralized region or distributed (remote) region.
· Enable flexible and efficient network slicing.
· Minimize dependencies among the Access Network (AN) and the Core Network (CN). The structure is described with a converged core community with a common AN - CN interface which integrates different Access Types e.g. 3GPP get entry to and non-3GPP get right of entry to.
· Support a unified authentication framework.
· Support "stateless" NFs, wherein the "compute" resource is decoupled from the "storage" aid.
· Support capability exposure.
· Support concurrent get right of entry to neighboring and centralized services. To assist low latency services and get admission to neighboring information networks, UP functions can be deployed near the Access Network.
· Support roaming with each Home routed traffic in addition to Local breakout site visitors within the visited PLMN.
· Wherever applicable, outline procedures (i.e. the set of interactions between network functions) as offerings, so that their re-use is possible.
