A.5.5.2A.1 Test Purpose and Environment
The purpose of this test is to verify the requirement for the cell re-selection delay in CELL_FACH state in section 5.5.2.1.2.
This scenario implies the presence of 2 carriers and 6 cells as given in tables A.5.4AA and A.5.4AB. The UE is requested to monitor neighbouring cells on 2 carriers. The maximum repetition period of the relevant system info blocks that needs to be received by the UE to camp on a cell shall be 1280 ms. Cell 1 and cell 2 shall belong to different Location Areas.

A.5.5.2A.2 Test Requirements
The cell re-selection delay is defined as the time from the beginning of time period T2, to the moment when the UE camps on Cell 1, and starts to send preambles on the PRACH for sending the RRC CONNECTION REQUEST message to perform a Location Registration on cell 1.
The cell re-selection delay shall be less than 2 s.
The rate of correct cell reselections observed during repeated tests shall be at least 90%.
NOTE: The cell re-selection delay can be expressed as: 
,
where:
Tmeasurement,inter See section 8.4a.2.3.2 as 480 ms in this case
TIU 10msec
TSI Maximum repetition period of relevant system info blocks that needs to be received by the UE to camp on a cell. 1280 ms is assumed in this test case.
TRA:TRA is a delay is caused by the physical random access procedure described in TS 25.214 section 6.1. A persistence value is assumed to be 1 in this test case and therefore TRA in this test case is 40 ms.
This gives a total of 1.83 s, allow 2s in the test case.
