Parameters
ueLteDevicethe Ipv4-enabled device of the UE, normally connected via the LTE radio interface
imsithe unique identifier of the UE
tftthe Traffic Flow Template of the new bearer
bearerstruct describing the characteristics of the EPS bearer to be activated

◆ AddEnb()

virtual void ns3::EpcHelper::AddEnb ( Ptr< Node enbNode,
Ptr< NetDevice lteEnbNetDevice,
std::vector< uint16_t >  cellIds

lteEnbNetDevicethe LteEnbNetDevice of the eNB node
cellIdsIDs of cells served by this eNB

Implemented in ns3::PointToPointEpcHelper, ns3::NoBackhaulEpcHelper, and ns3::EmuEpcHelper.

Parameters
enbeNB peer of the S1 interface
enbAddresseNB IPv4 address of the S1 interface
sgwAddressSGW IPv4 address of the S1 interface
cellIdscellIds of the eNB

Implemented in ns3::NoBackhaulEpcHelper.

◆ AddUe()

virtual void ns3::EpcHelper::AddUe ( Ptr< NetDevice ueLteDevice,
uint64_t  imsi 
)
pure virtual

Notify the EPC of the existence of a new UE which might attach at a later time.

Parameters
ueLteDevicethe UE device to be attached
imsithe unique identifier of the UE

Implemented in ns3::NoBackhaulEpcHelper.

◆ AddX2Interface()

virtual void ns3::EpcHelper::AddX2Interface ( Ptr< Node enbNode1,
Ptr< Node enbNode2

pure virtual

Add an X2 interface between two eNB.

Parameters
enbNode1one eNB peer of the X2 interface
enbNode2the other eNB peer of the X2 interface

Implemented in ns3::NoBackhaulEpcHelper, and ns3::EmuEpcHelper.

◆ AssignStreams()

virtual int64_t ns3::EpcHelper::AssignStreams ( int64_t  stream)

◆ AssignUeIpv4Address()

virtual Ipv4InterfaceContainer ns3::EpcHelper::AssignUeIpv4Address ( NetDeviceContainer  ueDevices)

◆ AssignUeIpv6Address()

virtual Ipv6InterfaceContainer ns3::EpcHelper::AssignUeIpv6Address ( NetDeviceContainer  ueDevices)
pure virtual

Assign IPv6 addresses to UE devices.

Parameters
ueDevicesthe set of UE devices
Returns
the interface container,
See also
Ipv6AddressHelper::Assign() which has similar semantics

Implemented in ns3::NoBackhaulEpcHelper.

◆ DoDispose()

void ns3::EpcHelper::DoDispose ( void  )
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.

Reimplemented in ns3::PointToPointEpcHelper, and ns3::NoBackhaulEpcHelper.

Definition at line 55 of file epc-helper.cc.

◆ GetPgwNode()

virtual Ptr<Node> ns3::EpcHelper::GetPgwNode ( ) const
pure virtual

Get the PGW node.

Returns
a pointer to the PGW node The primary use intended for this method is to allow the user to configure the SGi interface of the PGW, i.e., to connect the PGW to the internet.

Implemented in ns3::NoBackhaulEpcHelper.

◆ GetSgwNode()

virtual Ptr<Node> ns3::EpcHelper::GetSgwNode ( ) const
pure virtual

Get the SGW node.

Returns
a pointer to the SGW

Implemented in ns3::NoBackhaulEpcHelper.

◆ GetTypeId()

TypeId ns3::EpcHelper::GetTypeId ( void  )
static

Register this type.

Returns
The object TypeId.

◆ GetUeDefaultGatewayAddress()

virtual Ipv4Address ns3::EpcHelper::GetUeDefaultGatewayAddress ( )
pure virtual
Returns
the IPv4 address of the Default Gateway to be used by UEs to reach the internet

◆ GetUeDefaultGatewayAddress6()

virtual Ipv6Address ns3::EpcHelper::GetUeDefaultGatewayAddress6 ( )
pure virtual
Returns
the IPv6 address of the Default Gateway to be used by UEs to reach the internet

Implemented in ns3::NoBackhaulEpcHelper.
