IRAT Test Case Description

T01

IRAT Mobility Test

T01-01 L2U IRAT T01-0101 LTE to UMTS cell reselection, LTE has higher cell priority Objective If a UMTS cell’s signal quality is better than the threshold and the serving LTE cell’s signal quality is worse than the threshold of a UE in idle mode, the UE will be directed to the UMTS cell by cell reselection. This test case aims to verify that the eNodeB supports inter-RAT reselection for UEs in idle mode when the UEs move from LTE cells to UMTS cells. Network Diagram Lab test scenario:

Field test scenario: field test network

In most cases, an LTE cell is assigned a higher priority than a GERAN cell. This test case aims to verify that when a GERAN cell has better signal quality than an LTE cell, a UE in idle mode is directed to the GERAN cell by cell reselection even if the LTE cell is assigned a higher cell-reselection priority than the GERAN cell.
