A.5.6.1.2 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 CELL UPDATE message with cause value "cell reselection" in Cell 1.

The cell re-selection delay shall be less than 8 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: TevaluateFDD + TSI,

where:

TevaluateFDD: See section 5.6.2.

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 7.68 s, allow 8s in the test case.

A.5.6.3 Cell re-selection during an MBMS session, one UTRAN inter-frequency and 2 GSM cells present in the neighbour list

A.5.6.3.1 Test Purpose and Environment

The purpose of this test is to verify the requirement for the GSM BSIC identification for UEs in an MBMS PTM session according to section 4.2.2.3 and 4.2.2.5. Furthermore, the required functionality on the limitation of measurements in dependence of the MBMS TTI as specified in section 4.2.2.9 are tested.

This scenario implies the presence of 1 UTRAN serving cell, 1 UTRAN inter-frequency cell and 2 GSM cells of which one is to be re-selected. The UE is requested to monitor neighbor cells on 2 UMTS carriers (Channel 1, Channel 2) and 12 GSM cells. Test parameters are given in Tables A.5.8A, A5.8B, A.5.8C, A.5.8D and A.5.8E.

A.5.6.3.2 Test Requirements

The cell re-selection delay is defined as the time from the beginning of time period T3, to the moment when the UE camps on Cell 3, and starts to send the RR Channel Request message for location update to Cell 3.

The cell re-selection delay shall be less than 2,75 s + TBCCH, where TBCCH is the maximum time allowed to read BCCH data from GSM cell [21].

During T1 and T2 the MTCH SDU ER shall not exceed 4.0%.

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: Max(3* TmeasureFDD, TmeasureGSM+DRX cycle length) + TBCCH, where:

TmeasureFDD See Table 4.1 in section 4.2.2.

TmeasureGSM See Table 4.1 in section 4.2.2.

DRX cycle length 160mss see Table A.4.7.A

TBCCH Maximum time allowed to read BCCH data from GSM cell [21].
According to [21], the maximum time allowed to read the BCCH data, when being synchronized to a BCCH carrier, is 1.9 s.

This gives a total of 2.72 s + TBCCH, allow 2.75 s + TBCCH in the test case.
