RRC (Radio Resource Control) layer for LTE/NR networks.

Contains functional submodules corresponding to RRC procedures:

• registration: registers the node with the Binder, sets up the interface
• drbTable: the configuration of the node's data radio bearers
• bearerManagement: sets up and tears down data radio bearers
• connectionControl: the node's control-plane entry point, which the control plane of other nodes and the node's own data path talk to: ConnectionControlEnb at a base station, ConnectionControlUe at a UE (the LTE leg's; its handover decisions are the serving base station's, its execution the UE's)
• nrConnectionControl: the NR leg's ConnectionControlUe at a dual-stack UE

The D2D-specific submodules (d2dModeController, d2dModeSelection) are added by the RrcD2D subtype.

Known subclasses

Name	Type	Description
RrcD2D	compound module	D2D-capable variant of the Rrc layer. It adds the D2D mode controller (which coordinates RLC TX-queue draining across a mode switch) and, on the eNB/gNB side (hasD2DModeSelection==true), the periodic D2D mode selection module. Selected via 'rrc.typename' by the D2D-capable NICs.

Parameters

Name	Type	Default value	Description
interfaceTableModule	string
routingTableModule	string
hasConnectionControl	bool	false
hasNrConnectionControl	bool	false

Properties

Name	Value	Description
display	i=block/control
