Member Function Documentation

uint16_t ns3::LteEnbRrc::AddUe ( UeManager::State state )

private

Allocate a new RNTI for a new UE.

This is done in the following cases:

T-C-RNTI allocation upon contention-based MAC Random Access procedure
target cell RNTI allocation upon handover

Parameters

state the initial state of the UeManager

Returns: the newly allocated RNTI

Here is the caller graph for this function:

uint8_t ns3::LteEnbRrc::AddUeMeasReportConfig ( LteRrcSap::ReportConfigEutra config )

Add a new UE measurement reporting configuration.

Parameters

config the new reporting configuration

Returns: the measurement ID (measId) referring to the newly added reporting configuration

Assuming intra-frequency environment, the new measurement reporting configuration will be automatically associated to the only measurement object (i.e., a new measurement identity will be automatically created).

Can only be called before the start of simulation.

void ns3::LteEnbRrc::AddX2Neighbour ( uint16_t cellId )

Add a neighbour with an X2 interface.

Parameters

		uint8_t	dlBandwidth,
		uint16_t	ulEarfcn,
		uint16_t	dlEarfcn,
		uint16_t	cellId
	)

Configure cell-specific parameters.

Parameters

ulBandwidth	the uplink bandwidth in number of RB
dlBandwidth	the downlink bandwidth in number of RB
ulEarfcn	the UL EARFCN
dlEarfcn	the DL EARFCN
cellId	the ID of the cell

Configure cell-specific parameters and propagate them to lower layers. The parameters include bandwidth, EARFCN (E-UTRA Absolute Radio Frequency Channel Number), and cell ID.

In addition to parameter configuration, this function also performs several other tasks:

Initializing UE measurement (i.e. measurement object and quantity configuration), which is expected to be further configured through LteEnbRrc::AddUeMeasReportConfig;
Enabling MIB (Master Information Block) broadcast transmission
Enabling SIB (System Information Block) broadcast transmission

Typically runs when the eNodeB NetDevice is installed, for instance by LteHelper::InstallEnbDevice (i.e. before the simulation starts).

Warning: Raises an error when executed more than once.

protectedvirtual

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

Subclasses are expected to implement their real destruction code in an overriden 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.

void ns3::LteEnbRrc::SetCsgId	(	uint32_t	csgId,

	)

Associate this RRC entity with a particular CSG information.

Parameters

csgId	the intended Closed Subscriber Group identity
csgIndication	if TRUE, only CSG members are allowed to access the cell

CSG identity is a number identifying a Closed Subscriber Group which the cell belongs to. eNodeB is associated with a single CSG identity.

The same CSG identity can also be associated to several UEs, which is equivalent as enlisting these UEs as the members of this particular CSG. When the CSG indication field is set to TRUE, only UEs which are members of the CSG (i.e. same CSG ID) can gain access to the eNodeB, therefore enforcing closed access mode. Otherwise, the eNodeB operates as a non-CSG cell and implements open access mode.

This restriction only applies to initial cell selection and EPC-enabled simulation.
