|
a) The SS activates the carriers. The MS is not paged on carrier 1. The SS monitors carriers 1 and 2.
b) The MS is switched on.
c) The SS changes the BSIC of carrier 2 by changing the Base Station Colour Code (BCC) part of the BSIC. The SS also changes the RXLEV_ACCESS_MIN in the BCCH data of carrier 2 to be -100 dBm.
NOTE: With the above change to the BCCH data the C2 of carrier 2 becomes 20 whereas the C2 of carrier 1 stays at 15.

20.21.14.4.2 Procedure
|
a) The SS activates the carriers. The SS monitors for RA attempts from the MS on carriers 1, 2 and 3 for the duration of the test.
b) The MS is switched on.
c) 50 s after switch on, an emergency call is initiated on the MS.
d) The SS changes the CBA of carrier 1 to 0.
NOTE 1: The MS should reselect to carrier 1 because it should not take into account the CELL_RESELECT_HYST value of 14 but use 0 instead.
e) After 345 s an emergency call is initiated on the MS.
NOTE 2: 330 s to detect change of BCCH data, 15 s to perform reselection of carrier 1, since the MS already has a running average on carrier 1.

20.21.15.1 Definition
|
While camped on a cell of the selected PLMN the MS may need to select a different cell in order to fulfil the normal service state. This ensures that the MS is camped on a cell from which it can reliably decode downlink data and with which it has a high probability of communications on the uplink.
This process goes on while camping on a cell which pertains to an LA which is placed in the list of "forbidden LAIs for regional provision of service".

|
20.21.15.2 Conformance requirement
|
1. In response to a registration attempt, when receiving an LU reject with cause value "LA not allowed", the MS stores this LAI in a list of "forbidden LAIs for regional provision of service", to prevent repeated attempts to access a cell of the forbidden LA, 3GPP TS 03.22, subclause 3.3.
2. If the MS has received the cause 'LA not allowed', it shall ignore this fact when selecting a cell to camp on, i.e. it shall not reject a cell for camping on because that cell is part of a LA where this cause has been received, 3GPP TS 03.22, subclause 3.5.4.
3. In response to a registration attempt, when receiving an LU reject with cause value "LA not allowed", the MS continues to perform normal cell-reselection, 3GPP TS 03.22, subclause 4.4.2
4. A new LU attempt shall only be performed when a new LA (or new PLMN) is entered according to the cell reselection procedure, 3GPP TS 03.22, subclause 3.3 and figure 4.
NOTE: LA stands for "Location Area" and LU stands for "Location Update".

20.21.15.3 Test purpose
|
1. To verify that if an LU is rejected with cause "LA not allowed" that the LAI of that cell is written into a forbidden list which prevents the MS from performing LU onto another cell in that LA. This is verified indirectly in test purposes 2, 3 and 4.
2. To verify that the MS will not reject a cell for camping on because that cell is part of a LA in the list of "forbidden LAIs for regional provision of service". This is verified indirectly by making the MS attempt an emergency call and checking that the channel request message is transmitted on the correct cell.
3. To verify that the MS when receiving an LU reject with cause value "LA not allowed", the MS continues to perform normal cell-reselection:
Cell reselection is triggered if there is a better cell (in terms of the path loss criterion C2) in the same LA, or a much better cell in another LA of the selected PLMN (using the CRH parameter). 3GPP TS 03.22, subclauses 3.4 and 4.5.
4. To verify that a new LU attempt will be performed when a new LA (or new PLMN) is entered, 3GPP TS 03.22, subclause 3.3 and figure 4.

20.21.15.4.2 Procedure
|
a) The SS activates the carriers. The SS monitors all RA requests from MS on carriers 1, 2 and 3 until step e) has been completed. Only idle-paging is sent on all channels.
b) The MS is switched on.
c) When the MS performs an IMSI attach onto carrier 1, the SS shall reject it with cause "LA not allowed".
d) 30 s after the MS has returned to idle mode (channel release after LU reject), the MS is manually commanded to set up an emergency call.
NOTE 1: C2 of carrier 3>C2 of carrier 1. Carriers 1 and 3 belong to the same LA.
e) The SS rejects the CM service request from the MS, with a CM service reject message with cause value #17 (Network Failure).
NOTE 2: Cause values #4 (IMSI unknown in VLR) or #6 (Illegal ME) lead to unwanted behaviour of the mobile.
f) 10 s after the MS has returned to idle mode (channel release after CM service reject), the SS increases the level of carrier 2 to 65 dBV emf().
NOTE 3: C2 of carrier 2 = 30, now larger than C2 of carrier 3 + CRH.
g) The SS shall accept any LU on carrier 2.

|
a) The MS is switched on. On carrier 1 valid layer 3 messages shall be sent in the paging blocks, but not paging the MS (idle paging). On carrier 2 the MS is paged continuously in all paging blocks.
b) After 40 s the SS sends corrupted data (using random data, wrong parity bits see 3GPP TS 05.03, subclauses 4.3 and 4.1.2 or other lower layer error) in four successive paging blocks to carrier 1 and then reverts to sending normal data.
NOTE 1: Sending corrupted, i.e. non-decodable data on four successive paging blocks should decrease the DSC to 2.
c) The SS monitors all accesses on both carriers for 30 s.
d) The SS sends corrupted data in five successive paging blocks to carrier 1 and then reverts to sending normal data.
NOTE 2: Sending random, data on five successive paging blocks should decrease the DSC to < 0 and cause a cell reselection.
e) The SS monitors all accesses on both carriers for 30 s.

a) The MS is switched on. Idle paging is sent on carrier 1.
b) After the MS indicates service the SS reduces the transmit level of carrier 1 to 13 dBV emf() (so that C1 of carrier 1 becomes ‑10) and turns on a new carrier (carrier 2) at a level of 33 dBV emf(). Carrier 2 shall not be in the MS BA list (i.e. it shall not be one of the carriers that MS has been monitoring after camped on carrier 1).
c) The SS shall monitor all accesses on carriers 1 and 2 for 60 s.
NOTE: The access on carrier 2 should not take longer than 50 s. (5 s to rxlev averages, 5 s for C1 < 0 duration, 10 s for searching another suitable cell, 30 s for cell selection), 60 s is a safe time to wait.

1. To verify that if an LU is rejected with cause "Roaming not allowed in this LA", that the LAI of that cell is written into a forbidden list which prevents the MS from camping onto any cell in that LA.
2. To verify that if the MS has received the cause "Roaming not allowed in this LA", in response to a LU attempt, the Network Selection Procedure is initiated. This is verified indirectly by test purpose 3, in that the new LA is accessed as part of cell selection, hence CRH is disregarded.
3. To verify that if an LU is rejected, when attempting LU in a LA with LAI = LAI1, with cause "Roaming not allowed in this LA" and only cells of the selected PLMN are available, the MS will only camp and attempt LU in any LA with LAI <> LAI1.

20.21.19.2 Conformance requirement
|
1. When the SS releases a TCH or SDCCH and returns to idle mode, it shall, as quickly as possible camp on the BCCH carrier of the cell whose channel has just been released. If the full BCCH data for that cell was not decoded in the preceding 30 s, the MS shall then attempt to decode the full BCCH data. Until the MS has decoded the BCCH data required for determining the paging group, it shall also monitor all paging blocks on timeslot 0 of the BCCH carrier for possible paging messages that might address it. If the MS receives a page before having decoded the full BCCH data for the cell, the MS shall store the page and respond once the full BCCH data has been decoded, provided that the cell is not barred and the MSs access class is allowed. 3GPP TS 05.08, subclause 6.7.

20.21.19.3 Test purpose
|
1. To verify that on release of a TCH or an SDCCH, the MS camps as quickly as possible on the BCCH carrier of the cell whose channel has just been released.
NOTE: This is implicitly tested by the MS responding to a paging request. The decoding of BCCH data cannot be explicitly tested. However, the MS shall monitor for paging messages which may address it if it decodes the BCCH.
