Detailed Description

Testing a handover algorithm, verifying that it selects the right target cell when more than one options available.

Part of the lte-handover-target test suite.

The test case will run a 1-second LTE-EPC simulation using the parameters provided to the constructor function.

Constructor & Destructor Documentation

LteHandoverTargetTestCase::LteHandoverTargetTestCase	(	std::string	name,
		Vector	uePosition,
		uint8_t	gridSizeX,
		uint8_t	gridSizeY,
		uint16_t	sourceCellId,
		uint16_t	targetCellId,
		std::string	handoverAlgorithmType
	)

Construct a new test case and providing input parameters for the simulation.

Parameters

name	the name of the test case, to be displayed in the test result
uePosition	the point in (x, y, z) coordinate where the UE will be placed in the simulation
gridSizeX	number of eNodeBs in a row
gridSizeY	number of eNodeBs in a column
sourceCellId	the cell ID of the eNodeB which the UE will be initially attached to in the beginning of simulation, and also the eNodeB which will "shutdown" in the middle of simulation
targetCellId	the cell ID of the expected eNodeB where the UE will perform handover to after the "shutdown" of the source cell
handoverAlgorithmType	the type of handover algorithm to be used in all eNodeBs
