Converged Core Overview
The converged core solution provides an advanced, cloud native, converged control plane with the capability to support 4G and 5G devices, and use cases.
Important | This release supports only the cloud-native integrated S-GW and SMF instance with S5C and cnSGWc functionalities. |
The converged core solution removes the operational complexity by providing a unified core network to handle all types of subscribers and use cases.
The operator has the following benefits:
-
Improves the overall network efficiency by reducing signaling between cnSGWc and SMF while handling a 4G subscriber or handoff from 5G to 4G coverage area.
-
Reduces latency introduced due to the extra hop SGW-U for a subscriber in 4G coverage area by collapsing the data path in the Converged UPF, thus improving overall user experience.
-
Ability to use a unified subscriber policy and billing infrastructure using SBA interfaces for 4G and 5G devices.
The solution supports the following converged control plane and user plane functions:
-
Converged Control Plane Function:
-
Integrated S-GW and SMF network functions as a single deployment, under a single Kubernetes namespace, to support 4G and 5G devices from E-UTRAN/NR (converged core gateway)
-
Support for logical network functions (data only)
-
-
Converged User Plane Function:
-
Integrated UPF and SGW-U functionalities as a single network function
-
Simultaneous support for N4 and Sxa interfaces
-
Terminate multiple control planes in a single deployment
-
