Detailed Description

The class implements Component Carrier Manager (CCM) that operates using the Component Carrier Manager SAP interfaces.

CCM receives measurement reports from an eNode RRC instance and is forwarding calls from RLC to MAC layer, and from MAC to RLC.

This class is an abstract class intended to be inherited by subclasses that will implement its virtual methods. The subclasses are compatible with the LteEnbNetDevice class, and are accessible using namespace-based access through ns-3 Config subsystem, and can be installed and configured by LteHelper class.

The communication with the eNodeB RRC instance is done through the Component Carrier Manager SAP interface. The LteEnbComponentCarrierManager instance corresponds to the "provider" part of this interface, while the eNodeB RRC instance takes the role of the "user" part. The following code skeleton establishes the connection between both instances:

Ptr<LteEnbRrc> rrc = ...; Ptr<LteComponentCarrierManager> ccmEnb = ...; rrc->SetLteCcmRrcSapProvider (ccmEnb->GetLteCcmRrcSapProvider ()); ccmEnb->SetLteCcmRrcSapUser (rrc->GetLteCcmRrcSapUser ())

Similarly, LteEnbComponentCarrierManager instance communicates with MAC, and it takes the role of the "user".

However, user rarely needs to use the above code, since it has already been taken care by LteHelper::InstallEnbDevice.

Member Function Documentation

◆ DoDispose()

void ns3::LteEnbComponentCarrierManager::DoDispose ( )

overrideprotectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::Object.

Reimplemented in ns3::NoOpComponentCarrierManager.

Definition at line 39 of file lte-enb-component-carrier-manager.cc.

◆ DoReportUeMeas()

virtual void ns3::LteEnbComponentCarrierManager::DoReportUeMeas	(	uint16_t	rnti,
		LteRrcSap::MeasResults	measResults )

protectedpure virtual

Implementation of ReportUeMeas.

Parameters

rnti	Radio Network Temporary Identity, an integer identifying the UE where the report originates from
measResults	a single report of one measurement identity

Implemented in ns3::NoOpComponentCarrierManager.

◆ GetLteCcmMacSapUser()

LteCcmMacSapUser * ns3::LteEnbComponentCarrierManager::GetLteCcmMacSapUser ( )

virtual

This function returns a pointer to the LteCcmMacSapUser interface, which is used by MAC to communicate to CCM when e.g.

UL buffer status report is received, or to notify CCM about PRB occupancy, and similar. Functions that are specific for the communication between MAC and CCM.

Returns: LteCcmMacSapUser*
