DrbTable Class Reference¶

The node's data radio bearer configuration, owned by RRC.

Holds two collections of ~DrbDesc records, both keyed by (peer node, DRB id):

• The CONFIGURED bearers, authored in the BearerConfigurator, delivered by the serving base station (see ConnectionControlEnb::pushDrbToRrcs()) and taken in through BearerManagement::configureDrb(): the bearers this node is configured with, before and independent of their establishment. On the UE side entries are keyed by NODEID_NONE ("my serving node"); on the gNB side by the UE's node id. These entries persist for the whole simulation. This table does not author them and does not read them from a parameter.
• The ESTABLISHED bearers: ~BearerManagement fills this in as it establishes bearers, and drops entries together with the bearer's PDCP entity.
