Member Function Documentation

void ns3::EpcUeNas::ActivateEpsBearer	(	EpsBearer	bearer,
		Ptr< EpcTft >	tft
	)

Activate an EPS bearer

Parameters

bearer	the characteristics of the bearer to be created
tft	the TFT identifying the traffic that will go on this bearer

void ns3::EpcUeNas::Connect	(	uint16_t	cellId,
		uint16_t	earfcn
	)

instruct the NAS to go to ACTIVE state, i.e., EMM Registered + ECM Connected Since RRC Idle Mode cell selection is not supported yet, we force the UE RRC to be camped on a specific eNB.

Parameters

cellId	the id of the eNB to camp on
earfcn	the DL frequency of the eNB

Here is the caller graph for this function:

void ns3::EpcUeNas::DoDispose ( void )

virtual

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.
