Detailed Description

Testing UE measurements in LTE with simulation of 1 eNodeB and 1 UE in piecewise configuration and 120 ms report interval.

During the simulation the placement of UE is being changed several times. Four different cases are considered: UE is very near to eNodeB, UE is near to eNodeB, UE is far from eNodeB and UE is very far from eNodeB. Test checks if the measurments correspond to the real conditions of the UE, i.e. wnen the signal from serving cell becomes weak, the measurements should also start to correspond to the new channel conditions. Additionally, it is checked if UE detects some neighboring signal, if it does the test fails because there is no neighbor in this configuration. Also, test checks if the reporting occurs at intervals that it should according to the measurements configuration. If it occurs in some different time stamp the test will fail.

◆ RecvMeasurementReportCallback()

void LteUeMeasurementsPiecewiseTestCase1::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
