Member Function Documentation

void ns3::EpcMme::AddBearer	(	uint64_t	imsi,
		Ptr< EpcTft >	tft,
		EpsBearer	bearer
	)

Add an EPS bearer to the list of bearers to be activated for this UE. The bearer will be activated when the UE enters the ECM connected state.

Parameters

imsi	UE identifier
tft	traffic flow template of the bearer
bearer	QoS characteristics of the bearer

void ns3::EpcMme::AddEnb	(	uint16_t	egci,
		Ipv4Address	enbS1UAddr,
		EpcS1apSapEnb *	enbS1apSap
	)

Add a new ENB to the MME.

Parameters

imsi	the unique identifier of the UE
enbS1apSap	the ENB side of the S1-AP SAP

Here is the caller graph for this function:

void ns3::EpcMme::AddUe ( uint64_t imsi )

Add a new UE to the MME. This is the equivalent of storing the UE credentials before the UE is ever turned on.

Parameters

imsi	the unique identifier of the UE

void ns3::EpcMme::DoDispose ( void )

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.
