Detailed Description

Base helper class to handle the creation of the EPC entities.

Introspection did not find any typical Config paths.

This class provides the API for the implementation of helpers that allow to create EPC entities and the nodes and interfaces that host and connect them.

No Attributes are defined for this type.
No TraceSources are defined for this type.
Size of this type is 32 bytes (on a 64-bit architecture).

Member Function Documentation

virtual uint8_t ns3::EpcHelper::ActivateEpsBearer	(	Ptr< NetDevice >	ueLteDevice,
		uint64_t	imsi,
		Ptr< EpcTft >	tft,
		EpsBearer	bearer
	)

pure virtual

Activate an EPS bearer, setting up the corresponding S1-U tunnel.

Parameters

ueLteDevice	the Ipv4-enabled device of the UE, normally connected via the LTE radio interface
imsi	the unique identifier of the UE
tft	the Traffic Flow Template of the new bearer
bearer	struct describing the characteristics of the EPS bearer to be activated

Returns: bearer ID

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

virtual void ns3::EpcHelper::AddEnb	(	Ptr< Node >	enbNode,
		Ptr< NetDevice >	lteEnbNetDevice,
		uint16_t	cellId
	)

pure virtual

Add an eNB to the EPC.

Parameters

enbNode	the previosuly created eNB node which is to be added to the EPC
lteEnbNetDevice	the LteEnbNetDevice of the eNB node
cellId	ID of the eNB

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

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

pure virtual

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

Parameters

ueLteDevice	the UE device to be attached
imsi	the unique identifier of the UE

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

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

pure virtual

Add an X2 interface between two eNB.

Parameters

enbNode1	one eNB peer of the X2 interface
enbNode2	the other eNB peer of the X2 interface

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

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

pure virtual

Assign IPv4 addresses to UE devices.

Parameters

ueDevices the set of UE devices

Returns: the interface container,

See also: Ipv4AddressHelper::Assign() which has similar semantics

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

void ns3::EpcHelper::DoDispose ( void )

virtual

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 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.

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

Definition at line 56 of file epc-helper.cc.

Here is the call graph for this function:

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

pure virtual

Returns: a pointer to the node implementing PGW functionality. Note that in this particular implementation this node will also hold the SGW functionality. The primary use intended for this method is to allow the user to configure the Gi interface of the PGW, i.e., to connect the PGW to the internet.

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

TypeId ns3::EpcHelper::GetTypeId ( void )

static
