Constructor & Destructor Documentation

ns3::EpcEnbApplication::EpcEnbApplication	(	Ptr< Socket >	lteSocket,
		Ptr< Socket >	s1uSocket,
		Ipv4Address	sgwAddress
	)

Constructor

Parameters

lteSocket	the socket to be used to send/receive packets to/from the LTE radio interface
s1uSocket	the socket to be used to send/receive packets to/from the S1-U interface connected with the SGW
sgwAddress	the IPv4 address at which this eNB will be able to reach its SGW

Member Function Documentation

void ns3::EpcEnbApplication::ErabSetupRequest	(	uint32_t	teid,
		uint16_t	rnti,
		uint8_t	lcid
	)

This method is triggered after the eNB received a S1-AP message of type E-RAB Setup Request by the MME and the RadioBearer has already been created

Parameters

teid	the Tunnel Endpoint IDentifier of the S1-bearer to be setup.
rnti	the unique ID of the UE on this eNB
lcid	the Logical Channel ID identifying the Radio Bearer
