NGEN-DC
NG-RAN E-UTRA-NR Dual Connectivity (Option 7)
Architecture where upgraded 4G ng-eNodeB is Master Node and 5G gNodeB is Secondary Node connected to 5GC.
Technical Explanation
In 3GPP Architecture Option 7 (NGEN-DC), upgraded 4G base stations (ng-eNodeB) connect directly to the 5G Core network as Master Nodes, using 5G gNodeBs as Secondary Nodes. It allows operators with 5GC to anchor users on 4G spectrum while delivering 5G user plane speeds.
Key Functions
- Connects upgraded 4G ng-eNodeB as Master Node to 5G Core
- Uses 5G gNodeB as Secondary Node to deliver high data rates
- Enables 5GC services (slicing) while anchoring control on 4G coverage
