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.

T01-0201 LTE to GERAN cell reselection for a PS attached UE in idle mode, LTE has higher cell priority

Objective

LTE to GERAN cell reselection is classified into two types: reselection to a higher-priority cell and reselection

to a lower-priority cell. 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.
