Member Function Documentation

void ns3::LteUeRrc::ApplyMeasConfig ( LteRrcSap::MeasConfig  mc )

private

Update the current measurement configuration m_varMeasConfig.

Parameters

mc	measurements to be performed by the UE

Implements Section 5.5.2 "Measurement configuration" of 3GPP TS 36.331. The supported subfunctions are:

• Measurement object removal
• Measurement object addition/ modification
• Reporting configuration removal
• Reporting configuration addition/ modification
• Quantity configuration
• Measurement identity removal
• Measurement identity addition/ modification

The subfunctions that will be invoked are determined by the content of the given measurement configuration.

Note the existence of some chain reaction behaviours:

• Removal of measurement object or reporting configuration also removes any impacted measurement identities.
• Removal of measurement identity also removes any associated reporting entry from m_varMeasReportList.
• Modification to measurement object or reporting configuration also removes any reporting entries of the impacted measurement identities from m_varMeasReportList.
• Modification to quantity configuration also removes all existing reporting entries from m_varMeasReportList, regardless of measurement identity.

Some unsupported features:

• List of neighbouring cells
• List of black cells
• CGI reporting
• Periodical reporting configuration
• Measurement gaps
• s-Measure
• Speed-dependent scaling

Warning

There is a possibility that the input argument (of type LteRrcSap::MeasConfig) may contain information in fields related to the unsupported features. In such case, the function will raise an error.

The measurement configuration given as an argument is typically provided by the serving eNodeB. It is transmitted through the RRC protocol when the UE joins the cell, e.g., by connection establishment or by incoming handover. The information inside the argument can be configured from the eNodeB side, which would then equally apply to all other UEs attached to the same eNodeB. See the LTE module's User Documentation for more information on configuring this.

void ns3::LteUeRrc::CancelEnteringTrigger ( uint8_t  measId )

private

Clear all the waiting triggers in m_enteringTriggerQueue which are associated with the given measurement identity.

Parameters

measId

the measurement identity to be processed, must already exists in m_enteringTriggerQueue, otherwise an error would be raised

Note

The function may conclude that there is nothing to be removed. In this case, the function will simply ignore quietly.

This function is used when the entering condition of the measurement identity becomes no longer true. Therefore all the waiting triggers for this measurement identity in m_enteringTriggerQueue have become invalid and must be canceled.

void ns3::LteUeRrc::CancelEnteringTrigger ( uint8_t  measId, uint16_t  cellId  )

private

Remove a specific cell from the waiting triggers in m_enteringTriggerQueue which belong to the given measurement identity.

Parameters

measId	the measurement identity to be processed, must already exists in m_enteringTriggerQueue, otherwise an error would be raised
cellId	the cell ID to be removed from the waiting triggers

Note

The function may conclude that there is nothing to be removed. In this case, the function will simply ignore quietly.

This function is used when a specific neighbour cell no longer fulfills the entering condition of the measurement identity. Thus the cell must be removed from all the waiting triggers for this measurement identity in m_enteringTriggerQueue.

void ns3::LteUeRrc::DoDispose ( void  )

privatevirtual

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.

void ns3::LteUeRrc::EvaluateCellForSelection ( )

private

Performs cell selection evaluation to the current serving cell.

Warning

This function is a part of the initial cell selection procedure, hence must be only executed during IDLE mode and specifically during the state when the UE just received the first SIB1 message from the serving cell.

This function assumes that the required information for the evaluation procedure have been readily gathered, such as measurement results, MIB, and SIB1. Please refer to the LTE module's Design Documentation for more details on the evaluation process.

If the cell passes the evaluation, the UE will immediately camp to it. Otherwise, the UE will pick another cell and restart the cell selection procedure.

void ns3::LteUeRrc::MeasurementReportTriggering ( uint8_t  measId )

private

Evaluate the reporting criteria of a measurement identity and invoke some reporting actions based on the result.

Parameters

measId

the measurement identity to be evaluated

Implements Section 5.5.4.1 "Measurement report triggering - General" of 3GPP TS 36.331. This function take into use the latest measurement results and evaluate them against the entering condition and the leaving condition of the measurement identity's reporting criteria. The evaluation also take into account other defined criteria, such as hysteresis and time-to-trigger.

The entering and leaving condition to be evaluated are determined by the event type of the measurement identity's reporting criteria. As defined in LteRrcSap::ReportConfigEutra, there 5 supported events. The gore details of these events can be found in Section 5.5.4 of 3GPP TS 36.331.

An applicable entering condition (i.e., the condition evaluates to true) will insert a new reporting entry to m_varMeasReportList, so measurement reports would be produced and submitted to eNodeB. On the other hand, an applicable leaving condition will remove the related reporting entry from m_varMeasReportList, so submission of related measurement reports to eNodeB will be suspended.

void ns3::LteUeRrc::SaveUeMeasurements ( uint16_t  cellId, double  rsrp, double  rsrq, bool  useLayer3Filtering  )

private

Keep the given measurement result as the latest measurement figures, to be utilised by UE RRC functions.

Parameters

cellId	the cell ID of the measured cell
rsrp	measured RSRP value to be saved (in dBm)
rsrq	measured RSRQ value to be saved (in dB)
useLayer3Filtering

Todo:

Remove the useLayer3Filtering argument

Implements Section 5.5.3.2 "Layer 3 filtering" of 3GPP TS 36.331. Layer-3 filtering is applied to the given measurement results before saved to m_storedMeasValues. The filtering is however disabled when the UE is in IDLE mode, i.e., saving unfiltered values.

Layer-3 filtering is influenced by a filter coefficient, which determines the strength of the filtering. This coefficient is provided by the active quantity configuration in m_varMeasConfig, which is configured by the LteUeRrc::ApplyMeasConfig. Details on how the coefficient works and how to modify it can be found in LTE module's Design Documentation.

void ns3::LteUeRrc::SendMeasurementReport ( uint8_t  measId )

private

Produce a proper measurement report from the given measurement identity's reporting entry in m_varMeasReportList and then submit it to the serving eNodeB.

Parameters

measId

the measurement identity which report is to be submitted.

Implements Section 5.5.5 "Measurement reporting" of 3GPP TS 36.331. Producing a measurement report involves several tasks such as:

• including the measurement results of the serving cell into the report;
• selecting some neighbour cells which triggered the reporting (i.e., those in cellsTriggeredList) to be included in the report;
• sorting the order of neighbour cells in the report by their RSRP or RSRQ measurement results (the highest comes first); and
• ensuring the number of neighbour cells in the report is under the maxReportCells limit defined by the measurement identity's reporting configuration.

The RSRP and RSRQ measurement results included in the report are expressed in 3GPP-specified range format. They are converted from dBm and dB units using EutranMeasurementMapping::Dbm2RsrpRange and EutranMeasurementMapping::Db2RsrqRange functions.

Measurement report is submitted to the serving eNodeB through the RRC protocol. The LteUeRrcSapUser::SendMeasurementReport method of the UE RRC SAP facilitates this submission.

After the submission, the function will repeat itself after a certain interval. The interval length may vary from 120 ms to 60 minutes and is determined by the report interval parameter specified by the measurement identity's reporting configuration.
