20.4 Cell reselection using TEMPORARY_OFFSET, CELL_RESELECT_OFFSET, POWER_OFFSET and PENALTY_TIME parameters
3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS
20.4.1 Definition
void
20.4.2 Conformance requirement
1. The MS shall be able to calculate correctly the path loss criterion parameter C2 used for cell reselection; 3GPP TS 05.08, subclause 6.4.
20.4.3 Test purpose
1. To verify that the MS calculates the C2 parameter correctly when the CELL_RESELECT_OFFSET, TEMPORARY_OFFSET and PENALTY_TIME parameters are used.
2. To verify DCS 1 800 MS correctly calculate the C2 parameter when the POWER_OFFSET parameter is present.

20.4.4.2 Procedure
For testing of all types of MS, the test procedure is performed for execution counter K = 1.For testing of DCS 1 800 Class 3 MS, the test procedure is performed for execution counter K = 1 and 2:
On execution counter K = 1, the POWER_OFFSET Parameter is not present.
On execution counter K = 2, the POWER_OFFSET parameter is present.
a) The SS activates carriers 1 and 2. The MS is not paged on carrier 1. The SS monitors carrier 2 for RA requests from the MS.
b) The MS is switched on.
c) The SS increases the level of carrier 2 to 54 dBVemf (C2 becomes 25 dB).
d) When the SS receives a response on carrier 2, the SS stops paging on that carrier and waits for 20 s (The MS should reselect and camp onto carrier 2).
e) The SS activates carriers 3 and 4 and continuously pages the MS on these carriers. The SS monitors carriers 3 and 4 for RA requests from the MS.
20.4.4.3 Requirements
For execution counter K = 1 and K = 2.
1) After step b), there shall be no response from the MS on carrier 2 within 50 s.
2) After step c), the MS shall respond on carrier 2 within 20 s of increasing the level of carrier 2.
3) After step e), there shall be no response from the MS on carrier 3 within 38 s of activating the carriers but, the MS shall respond on carrier 3 within 90 s. The response on carrier 3 shall be before any response on carrier 4.
NOTE: Minimum time of 38 s set by penalty timer on carrier 3 less 2 s tolerance. Maximum time, total of 33 s to read BCCH of carrier 3, 42 s for expiry of penalty timer on carrier 3, 15 s for reselection, since the MS will already have running averages on carriers 3 and 4, when the penalty timers expire, allow 90 s.
