Detailed Description

Testing UE measurements in LTE with simulation of 2 eNodeB and 1 UE in piecewise configuration and 240 ms report interval.

Here is intenisvely test events A1 and A2. A1 event should be triggered when the serving cell becomes better than a given threshold. A2 shall be triggered when the serving cell becomes worse than threshold. A3 event is triggered when the neighbour becomes offset better than the PCell. In this test UE is being transported several times during the simulation duration. Then the test checks if measurement report contains correct RSRP and RSRQ result, than if CQI info is correctly generated, if the reporting occurs at the correct time stamp in the simulation and according to the measurements configuration. It also checks if the reported values of RSRP and RSRQ are equal to expected reference values.

◆ RecvMeasurementReportCallback()

void LteUeMeasurementsPiecewiseTestCase2::RecvMeasurementReportCallback	(	std::string	context,
		uint64_t	imsi,
		uint16_t	cellId,
		uint16_t	rnti,
		LteRrcSap::MeasurementReport	report
	)

Triggers when eNodeB receives measurement report from UE, then perform verification on it.

The trigger is set up beforehand by connecting to the LteUeRrc::RecvMeasurementReport trace source.

Verification consists of checking whether the report carries the right value of RSRP or not, and whether it occurs at the expected time or not.

Parameters

context	the context
imsi	the IMSI
cellId	the cell ID
rnti	the RNTI
report	LteRrcSap::MeasurementReport
