Detailed Description

This application implements the Mobility Management Entity (MME) according to the 3GPP TS 23.401 document.

This Application implements the MME side of the S1-MME interface between the MME node and the eNB nodes and the MME side of the S11 interface between the MME node and the SGW node. It supports the following functions and messages:

Bearer management functions including dedicated bearer establishment
NAS signalling
Tunnel Management messages

Others functions enumerated in section 4.4.2 of 3GPP TS 23.401 are not supported.

◆ DoDispose()

void ns3::EpcMmeApplication::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::Application.
