Member Function Documentation

void ns3::LteEnbNetDevice::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::LteNetDevice.

Here is the call graph for this function:

void ns3::LteEnbNetDevice::DoInitialize ( void )

protectedvirtual

This method is called only once by Object::Initialize.

If the user calls Object::Initialize multiple times, DoInitialize is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject and AggregateObject from within this method.

void ns3::LteEnbNetDevice::SetCsgId ( uint32_t csgId )

Associate the eNodeB device with a particular CSG.

Parameters

csgId the intended Closed Subscriber Group identity

CSG identity is a number identifying a Closed Subscriber Group which the cell belongs to. eNodeB is associated with a single CSG identity.

The same CSG identity can also be associated to several UEs, which is equivalent as enlisting these UEs as the members of this particular CSG.

void ns3::LteEnbNetDevice::SetCsgIndication ( bool csgIndication )

Enable or disable the CSG indication flag.

Parameters

csgIndication if TRUE, only CSG members are allowed to access this cell

When the CSG indication field is set to TRUE, only UEs which are members of the CSG (i.e. same CSG ID) can gain access to the eNodeB, therefore enforcing closed access mode. Otherwise, the eNodeB operates as a non-CSG cell and implements open access mode.

Note: This restriction only applies to initial cell selection and EPC-enabled simulation.

Propagate attributes and configuration to sub-modules.

Several attributes (e.g., the bandwidth) are exported as the attributes of the LteEnbNetDevice from a user perspective, but are actually used also in other sub-modules (the RRC, the PHY, the scheduler, etc.). This method takes care of updating the configuration of all these sub-modules so that their copy of attribute values are in sync with the one in the LteEnbNetDevice.
