A.5.5.2.1 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.
The test parameters are given in tables A5.3 and A5.4. 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.

A.5.5.2.2 Test Requirements
The cell re-reselection 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 the CELL UPDATE message with cause value "cell reselection" in Cell 1.
The cell re-selection delay shall be less than 1.9 s.
The rate of correct cell reselections observed during repeated tests shall be at least 90%.
NOTE: The cell re-selection delay in this case is expressed as:
ms,
where:
Tmeasurement interis specified in 8.4.2.3.2 as 480 ms in this case.
TSI: The time required for receiving all the relevant system information data according to the reception procedure and the RRC procedure delay of system information blocks defined in 25.331 for a UTRAN cell.1280 ms is assumed in this test case.
NOTE: Since 1280 ms is one of the typical values for repeating system information blocks, TSI of 1280 ms could be increased by the RRC procedure delay in order to allow the SIB repetition period of 1280 ms.
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 1.9 s in the test case.
