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
Prerequisites 1.
The LTE/EPC system is in normal operation.
2.

report, eNodeB sends an RRC CONNECTION RELEASE message to the UE. The RRC CONNECTION RELEASE message with "redirected CarrierInfo" on the Uu interface indicates the UE redirection from the LTE cell to the GERAN cell. The Routing Area Update Request message appears in the Gb tracing log, indicating that the redirection procedure is successful. The data transmission in GERAN side is normal.
