A.4.5 UTRAN to E-UTRA Cell Reselection

A.4.5.1 E-UTRA FDD is of higher priority

A.4.5.1.1 Test Purpose and Environment

This test is to verify the requirement for the UTRA FDD to E-UTRA FDD inter-RAT cell reselection delay reported

in section 4.2.

The test scenario comprises two different cells, with cell 1 being the UTRA serving cell and cell 2 being the E-

UTRA cell to be re-selected to. Test parameters are given in Tables A.4.14, A.4.15, A.4.16. The test consists of

three successive time periods, with time duration of T1, T2, and T3, respectively. Both UTRA cell 1 and E-UTRA

cell 2 are already identified by the UE prior to the start of the test. Cell 2 is of higher priority than cell 1.

Cell 1 and cell 2 shall belong to different tracking areas. Furthermore, UE has not registered with network for the

tracking area containing cell 2.

A.4.5.1.2 Test Requirements

The cell re-selection delay is defined as the time from the beginning of time period T 3, to the moment when the UE

camps on Cell 2, and starts to send preambles on the PRACH for sending the RRC CONNECTION REQUEST

message to perform a Tracking Area Update procedure on Cell 2.

The cell re-selection delay shall be less than 81 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: Thigher_priority_search + TevaluateEUTRA + TSI, where:

Thigher_priority_search See section 4.2.2

TevaluateEUTRA See Table 4.2 in section 4.2.2.5a

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.

This gives a total of 80.48 s, allow 81 s in the test case.
