Detailed Description

Create an EPC network using EmuFdNetDevice.

This Helper will create an EPC network topology comprising of a single node that implements both the SGW and PGW functionality, and an MME node. The S1-U, X2-U and X2-C interfaces are realized using EmuFdNetDevice; in particular, one device is used to send all the traffic related to these interfaces.

Parameters

enbNode	the previously created eNB node which is to be added to the EPC
lteEnbNetDevice	the LteEnbNetDevice of the eNB node
cellIds	IDs of cells served by this eNB

Here is the call graph for this function:

◆ DoDispose()

void ns3::EmuEpcHelper::DoDispose ( )

overridevirtual

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.

Definition at line 99 of file emu-epc-helper.cc.

References ns3::NoBackhaulEpcHelper::DoDispose(), and NS_LOG_FUNCTION.

Here is the call graph for this function:

◆ GetInstanceTypeId()

TypeId ns3::EmuEpcHelper::GetInstanceTypeId ( ) const

overridevirtual

Get the most derived TypeId for this Object.

This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.

Returns: The TypeId associated to the most-derived type of this instance.

Implements ns3::ObjectBase.

Definition at line 93 of file emu-epc-helper.cc.

References GetTypeId().

Here is the call graph for this function:

◆ GetTypeId()

TypeId ns3::EmuEpcHelper::GetTypeId ( )

Register this type.

Returns: The object TypeId.
