Feature Description

New Radio Dual Connectivity (NR-DC) is a dual connectivity configuration using the 5G standalone core. In this configuration, both the primary and secondary RAN nodes are 5G gNBs. SMF supports 5G aggregation along with NR-DC to achieve higher 5G data rates.

This feature has the following key points:

  • Use NR-DC only for data traffic

  • Use only default flow for data traffic

  • One tunnel is sufficient

  • SMF requires no configuration

The NR-DC feaure is applicable to both roaming and non-roaming scenarios.
