Detailed Description

Service Access Point (SAP) offered by the eNodeB RRC instance to the handover algorithm instance.

This is the Handover Management SAP User, i.e., the part of the SAP that contains the eNodeB RRC methods called by the handover algorithm instance.

Member Function Documentation

◆ AddUeMeasReportConfigForHandover()

virtual std::vector< uint8_t > ns3::LteHandoverManagementSapUser::AddUeMeasReportConfigForHandover ( LteRrcSap::ReportConfigEutra reportConfig )

pure virtual

Request a certain reporting configuration to be fulfilled by the UEs attached to the eNodeB entity.

Parameters

reportConfig the UE measurement reporting configuration

Returns: the measurement identities associated with this newly added reporting configuration

The eNodeB RRC entity is expected to configure the same reporting configuration in each of the attached UEs. When later in the simulation a UE measurement report is received from a UE as a result of this configuration, the eNodeB RRC entity shall forward this report to the handover algorithm through the LteHandoverManagementSapProvider::ReportUeMeas SAP function.

Note: This function is only valid before the simulation begins.

Implemented in ns3::MemberLteHandoverManagementSapUser< C >.

Referenced by ns3::A2A4RsrqHandoverAlgorithm::DoInitialize(), and ns3::A3RsrpHandoverAlgorithm::DoInitialize().

Here is the caller graph for this function:

◆ TriggerHandover()

virtual void ns3::LteHandoverManagementSapUser::TriggerHandover	(	uint16_t	rnti,
		uint16_t	targetCellId )

pure virtual

Instruct the eNodeB RRC entity to prepare a handover.

Parameters

rnti	Radio Network Temporary Identity, an integer identifying the UE which shall perform the handover
targetCellId	the cell ID of the target eNodeB

This function is used by the handover algorithm entity when a handover decision has been reached.

The process to produce the decision is up to the implementation of handover algorithm. It is typically based on the reported UE measurements, which are received through the LteHandoverManagementSapProvider::ReportUeMeas function.
