20.22.31.1.1 Conformance requirement
|
When a cell reselection is initiated by the network for an individual mobile station, the cell change order procedure is started by sending a PACKET CELL CHANGE ORDER message to the mobile station on the PCCCH or PACCH.
Upon receipt of the PACKET CELL CHANGE ORDER message the mobile station shall start timer T3174.
When a cell reselection is made controlled by the network, the mobile station shall act upon the IMMEDIATE_REL value which has been received in the Packet Cell Change Order: if required, the mobile station shall abort any TBF in progress by immediately ceasing to decode the downlink, ceasing to transmit on the uplink, stopping all RLC/MAC timers except for timers related to measurement reporting. The mobile station shall then switch to the identified specified new cell and shall obey the relevant RLC/MAC procedures on this new cell.
To initiate a combined routing area updating procedure the MS sends the message ROUTING AREA UPDATE REQUEST to the network, starts timer T3330 and changes to state GMM-ROUTING-UPDATING-INITIATED and MM LOCATION UPDATING PENDING. The value of the update type IE in the message shall indicate "combined RA/LA updating". If for the last attempt to update the registration of the location area a MM specific procedure was performed, the value of the update type IE in the ROUTING AREA UPDATE REQUEST message shall indicate "combined RA/LA updating with IMSI attach". Furthermore the MS shall include the TMSI status IE if no valid TMSI is available.

20.22.31.1.7 Test procedure
|
a) The MS is switched on and completes GPRS Attach procedure (ready timer deactivated) on Cell A. MS is PDP context activated and brought into packet transfer mode.
b) The RF level of Cell A is reduced to -80 dBm. (C32 becomes 20).
c) The SS waits 15 s after the RF level of Cell A is reduced before sending Packet Cell Change Order, with the IMMEDIATE_REL bit set to FALSE, to the MS to select Cell C. The MS shall complete a combined RA/LA unpdate procedure on Cell C.
d) The RF level of Cell B is increased to -60 dBm. (C32 becomes 40).
e) The SS waits 15 s after increasing the RF level of Cell B to ensure no RA update takes place on Cells A or B.
NOTE: During the TBF, T3158 may expire and thus PACKET MEASUREMENT REPORT could be sent at any time while the downlink transfer is in progress. The SS shall be prepared for this.

|
When a cell reselection is initiated by the network for an individual mobile station, the cell change order procedure is started by sending a PACKET CELL CHANGE ORDER message to the mobile station on the PCCCH or PACCH.
Upon receipt of the PACKET CELL CHANGE ORDER message the mobile station shall start timer T3174.
When a cell reselection is made controlled by the network, the mobile station shall act upon the IMMEDIATE_REL value which has been received in the Packet Cell Change Order: if required, the mobile station shall abort any TBF in progress by immediately ceasing to decode the downlink, ceasing to transmit on the uplink, stopping all RLC/MAC timers except for timers related to measurement reporting. The mobile station shall then switch to the identified specified new cell and shall obey the relevant RLC/MAC procedures on this new cell.
To initiate the normal routing area updating procedure, the MS sends the message ROUTING AREA UPDATE REQUEST to the network, starts timer T3330 and changes to state GMM-ROUTING-AREA-UPDATING-INITIATED. The message ROUTING AREA UPDATE REQUEST shall contain the P-TMSI signature when received within a previous ATTACH ACCEPT or ROUTING AREA UPDATE ACCEPT message.
If the routing area updating request has been accepted by the network, a ROUTING AREA UPDATE ACCEPT message shall be sent to the MS. The network may assign a new P-TMSI and/or a new P-TMSI signature for the MS. If a new P-TMSI and/or P-TMSI signature have been assigned to the MS, it/they shall be included in the ROUTING AREA UPDATE ACCEPT message together with the routing area identification.
If the network operates in mode II or III, then a GPRS-attached MS that has the capability to be simultaneously GPRS-attached and IMSI-attached shall perform the (non-combined) Routing Area Update procedures, and either:
- access the non-GPRS common control channels for CS operation (the way that CS operation is performed in parallel with GPRS operation is an MS implementation issue outside the scope of the present document); or
- if CS operation is not desired, depending on system information that defines whether or not explicit detach shall be used, either:
- avoid all CS signalling (in which case the MS may be implicitly IMSI detached after a while); or
- perform an explicit IMSI detach via the non-GPRS common control channels (if the MS was already IMSI-attached).

• The MS shall keep track of two C1 values:
- C1a, the best C1 value experienced in the serving cell since last performing measurements for cell reselection, or, after cell selection, since selecting the serving cell; and
- C1b, the most recently evaluated C1 (i.e. the current C1 value)
Upon evaluating C1 it determines if the current C1 value (C1b) is less than the best C1 value (C1a) by more than C1_DELTA. C1_DELTA is calculated each time measurements for cell re-selection are performed, see subclause 6.6.1a.4. After cell selection, C1_DELTA shall be set to the value of the C1_DELTA_MIN parameter sent in SI13 for PEO and in EC SI 3 for EC operation – see 3GPP TS 44.018 [17].
The MS shall proceed as described in sub-clause 6.6.1a.4 if any of the following criteria are fulfilled:
- Cell selection has been completed and monitoring of non-serving cells for cell reselection has not yet been performed;
- C1 ≤ 0;
- A change in BSIC is detected;
- A downlink signalling failure is declared;
- C1a – C1b > C1_DELTA; or
- More than 24 hours have passed since the last evaluation of C1 and C2 of non-serving cells.

1) After step a), there should be no response form MS on carrier 2, C1(a and b) should be 10.2) after step b), there should be no response on carrier 2.
NOTE 1: C1(b) =5, C1a – C1b < C1_DELTA and C1_DELTA= C1_DELTA_MIN as initial value.
3) After step c) C1(a) should then be 20, there should be no response on carrier 2.
4) After step d) there should be a response on carrier 2 within 1min as reselection process is triggered by C1a – C1b > C1_DELTA and C2 of carrier 2 identifies this carrier as the best cell.
NOTE 2: As C1(b) =5, C1a – C1b > C1_DELTA and C1_DELTA= C1_DELTA_MIN here as C1 from Carrier 1 < C1 from Carrier 2 and C_DELTA=min(max(D=C1_Cell1 – C1_Cell2, C1_DELTA_MIN), C1_DELTA_MAX). After reselection, C1a of carrier 2 is now 50 after reselection.
5) After step e), there should be no response on carrier 1.
NOTE 3: As C1(b)=30, C1a – C1b > C1_DELTA as a 20 dB drop is generated on carrier 2 so a reselection measurement is triggered but carrier 2 is still considered as the best Cell (as per C2). After reselection, C1a of carrier 2 is updated to 30 as well (-70 ). After the reselection measurements the new C1_DELTA value is 15 (i.e. C1_DELTA_MAX) as D = C1 carrier 2 – C1 carrier 1 = 15 > C1_DELTA_MIN.
6) After step f), there should be no response on carrier 1, this is checked for 2 min.
NOTE 4:As C1(b) =20, C1a – C1b = 10 < C1_DELTA (as updated after step e) as a 10 dB drop is generated on carrier 2 but even if carrier 1 could be considered as the best cell, no reselection process is initiated as C1_DELTA is not C1_DELTA_MIN anymore.

|
A MS that has enabled PEO with eDRX shall, upon entering packet idle mode, initialize PCH_DSC to the value indicated by the PEO_DSC field of the SI 13 Rest Octets IE (see 3GPP TS 44.018 [17]). Thereafter, if the MS successfully decodes a message in its paging subchannel (i.e. using its nominal paging group) PCH_DSC is incremented by 1, but not beyond the initial value. Otherwise, it shall decrement PCH_DSC by 1 and begin monitoring PCH blocks according to the shortest eDRX cycle value (i.e. eDRX Cycle Value = 0000, see 3GPP TS 45.002 [22]). While monitoring PCH blocks according to the shortest eDRX cycle value the MS shall still monitor PCH paging occasions determined by its negotiated eDRX value. It repeats the process of incrementing/decrementing PCH_DSC based on the outcome of each attempted PCH decoding until it either successfully decodes a PCH/AGCH message (at which point it resumes monitoring only PCH blocks corresponding to its negotiated eDRX Cycle Value) or PCH_DSC = 0 at which point a downlink signalling failure shall be declared. A MS that has enabled PEO shall use a non-DRX mode period of zero seconds.
NOTE: The network sends the paging subchannel for a given MS every BS_PA_MFRMS multiframes or, in case DRX period split is supported, every 1/NDRX multiframes. An exception is the case of a MS that is using eDRX in which case the network sends paging messages using paging sub-channels as described in 3GPP TS 45.002 [22]. The requirement for network transmission on the paging subchannel is specified in 3GPP TS 44.018 [17] or 3GPP TS 44.060 [19], 3GPP TS 44.118 [20] or 3GPP TS 44.160 [21]. The MS is required to attempt to decode a message every time its paging subchannel is sent.

|
To verify that an MS that has enabled PEO and faces a Downlink Signalling Failure will use the PEO_DSC parameter:
1. To verify that the MS that has enabled PEO the PCH_DSC counter in accordance with the conformance requirement. This is verified indirectly.
2. To verify that whenever the MS successfully decodes a message on paging subchannel, the PCH_DSC is increased by 1. This is verified indirectly.
3 To verify that whenever the MS can not successfully decode a message on paging subchannel, the PCH_DSC decreased by 1. This is verified indirectly.
4. To verify that when the MS does not successfully decode a message in its paging subchannel (i.e. using its nominal paging group), it shall and begin monitoring PCH blocks according to the shortest eDRX cycle value and increment or decrement PCH_DSC accordingly.
4. To verify that when the PCH_DSC reaches 0, a downlink signalling failure shall be declared and the MS will perform cell reselection.

|
a) On carrier 1 valid layer 3 messages shall be sent in the MS 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 45.003, subclauses 4.3 and 4.1.2 or other lower layer error) in 8 successive PCH paging occasions to carrier 1 and then reverts to sending normal data.
NOTE 1: Sending corrupted, i.e. non-decodable data on 8 successive paging blocks should decrease the PCH_DSC to 2.
NOTE 2: The first occurrence of the PCH occasion is the MS paging block based on the eDRX cycle negotiated with the SS, the following 7 occurrences based on the lowest eDRX cycle (as per Conformance Requirement). The 8 occurrences last for 64 51 MF (~15s).
c) After 2 min (PCH_DSC should be 6), the SS sends corrupted data in 7 successive paging blocks to carrier 1 and then reverts to sending normal data.
NOTE 3: Sending random, data on 6 successive paging blocks should decrease the PCH_DSC to < 0 and cause a cell reselection.
NOTE 4: The first occurrence of the PCH occasion is the MS paging block based on the eDRX cycle negotiated with the SS, the following 6 occurrences based on the lowest eDRX cycle (as per Conformance Requirement). The 7 occurrences last for 56 51 MF (~13s).

20.22.33.1.1 Conformance requirement
|
An EC-GSM-IoT capable MS shall perform EC-GSM-IoT cell selection based on RLA_EC (see subclause 6.9). In case the MS also supports GPRS services using GPRS or EGPRS TBFs, non EC-GSM-IoT cell selection shall be based on RLA_GC (see subclause 6.9a). Therefore, following the RLA_C measurements described above, the MS shall perform a second search of the RF channels within its bands of operation, and measure:
• RLA_EC for the strongest EC-BCCH carrier, which might include the evaluation of several different carriers, on each RF channel that supports EC-GSM-IoT.
• RLA_GC for the strongest BCCH carrier on each RF channel that does not support EC-GSM-IoT, in case the MS supports GPRS or EGPRS TBFs.
The cell selected as a result of performing the cell selection procedure shall be the suitable cell (see 3GPP TS 43.022 [11]) with the highest measured value (i.e., RLA_EC or RLA_GC, whichever is applicable). When measuring candidate cells during the selection procedure, RLA_EC and RLA_GC measurements may be omitted (and the corresponding cells not considered for cell selection) for those candidate cells for which the measured RLA_C is more than CELL_SELECTION_RLA_MARGIN dB below the measured RLA_EC or RLA_GC of the best candidate cell identified to that point in the cell selection procedure. CELL_SELECTION_ RLA_MARGIN is broadcast in EC SI in cells supporting EC-GSM-IoT, and in SI in cells not supporting EC-GSM-IoT, see 3GPP TS 44.018 [17].
An EC-GSM-IoT capable MS performing measurements for cell selection on an EC-GSM-IoT capable cell shall search for frequency correction bursts and synchronization bursts carrying EC-SCH when identifying BCCH carriers, see subclause 6.9. Before selecting a BCCH carrier, the MS shall attempt to synchronize to it and read the EC-BCCH data. An EC-GSM-IoT capable MS attempting to synchronize to a BCCH carrier in search for an EC-GSM-IoT cell may assume that the cell is a non EC-GSM-IoT cell if no successful decoding of EC-SCH has been done within [2] s.
An EC-GSM-IoT capable MS shall be able to synchronize to the BCCH carrier of an EC-GSM-IoT cell within [2] s at reference sensitivity level. The maximum time allowed to read the EC-BCCH data, when being synchronized to a BCCH carrier of an EC-GSM-IoT cell, is [12] s or equal to the scheduling period for the EC-BCCH data, whichever is greater (see 3GPP TS 45.002 [22]) in ideal radio conditions. The MS is allowed to camp on a cell and access the cell after decoding all relevant EC-BCCH data.

The MS shall proceed as described in sub-clause 6.6.1a.4 if any of the following criteria are fulfilled:
- Cell selection has been completed and monitoring of non-serving cells for cell reselection has not yet been performed;
- C1 ≤ 0;
- A change in BSIC is detected;
- A downlink signalling failure is declared;
- C1a – C1b > C1_DELTA; or
- More than 24 hours have passed since the last evaluation of C1 and C2 of non-serving cells.
The MS need not monitor the BCCH carriers of the non-serving cells as long as none of these criteria are fulfilled.
[…]
For a MS that has enabled EC operation downlink signalling failure is declared if the MS fails to decode EC-SCH within [2.5] seconds during an attempt to synchronize to a cell (i.e. neither DSC nor PEO_DSC are used). A MS that has enabled EC operation shall use a non-DRX mode period of zero seconds.
A downlink signalling failure shall result in the MS performing the cell reselection procedure (i.e. if a better cell is found it is used).

20.24 SoLSA Cell Selection and Reselection
|
All GSM test cases presented in 3GPP TS 11.10 clause 20 are applicable for SoLSA ME with or without LSA SIM. Nevertheless, if LSA SIM are used, it must be checked that no LSA subscription matches the information broadcast by the cell. Otherwise, test cases dealing with cell reselection would fail.
The cell re-selection tests defined in the following sections apply to the SoLSA MS if an LSA support exists in the serving cell. Otherwise the SoLSA MS shall perform cell re-selection according to the idle mode procedures defined in clause 6 of 3GPP TS 05.08.
The SS transmits one BCCH carrier per cell as indicated in the initial conditions for each test. These are referred to as carrier 1, carrier 2, etc. Each of these cell control channels are non-combined with SDCCHs. It is assumed that the SS can simultaneously transmit seven BCCH carriers and monitor three random access channels. In some cases, a test is performed in multiple stages in order that the requirements can be tested within the above constraints.
For any SoLSA MS all the carriers are in its supported band(s) of operation. For an E-GSM mobile station at least one of the carriers is in the extension band and one of the carriers is in the primary band.
Unless otherwise stated in the method of test, in all of the tests of this subclause:
- The SS is continuously paging the SoLSA MS on all carriers at the start of the test and does not respond to RACH requests from the SoLSA MS. Where a test specifies that the SoLSA MS is not paged on a particular carrier, only idle paging is transmitted according to 3GPP TS 04.18, subclause 3.2.2.2.
- The default values of the system information data fields given in table 20.24.1 are used.
- The SIM is in the idle updated state in the default location area with a TMSI assigned at the beginning of each test.
- The ARFCNs used for the carriers in each test are chosen from those in table 20.24.1 with adjacent carriers separated by a minimum of three channels.
The absolute accuracy of the SoLSA MS signal level measurements is assumed to be ±6 dB. A difference of at least 8 dB is allowed for cases of discrimination between C1, C2 or C4 values and 0.
The relative accuracy of the SoLSA MS signal level measurements is assumed to be ±3 dB for the signal levels used in the tests of this subclause. A difference of at least 5 dB is allowed for cases of discrimination between C1, C2 or C4 values on different carriers.
NOTE 1: The accuracy of SoLSA MS signal level measurements is specified in 3GPP TS 05.08. For all of the tests in this subclause, the signal levels used are greater than 1 dB above reference sensitivity level.
NOTE 2: The tolerance on timers specified in 3GPP TS 05.08 is ±10 % except for PENALTY_TIME where it is ±2 s. In the tests of this subclause, the test requirements include these tolerances. Consequently, the times stated in the test requirement sometimes differ from the corresponding timer in the conformance requirement.
Where pulsed signals are specified, the SS tolerance on pulse width is ±2 % and the SS tolerance on power level ±1 dB.
NOTE 3: Additional to the abbreviations and definitions in 3GPP TR 21.905 the following definitions are used within this subclause.

General Remark
1) Elementary File EFSLL (3GPP TS 11.11, subclause 10.4.1.2)
The information regarding 'idle mode support' and 'LSA indication for idle mode' is contained on the SIM card, in the Elementary File EFSLL SoLSA LSA List (identifier '4F31') and, more precisely, in the 'Configuration Parameters' byte.
File EFSLL is represented in the table below, from 3GPP TS 11.11, subclause 10.4.1.2.
Each LSA is described by one record that is linked to an LSA Descriptor file. Each record contains information of the PLMN, priority of the LSA, information about the subscription and may also contain a text string and/or an icon that identifies the LSA to the user. The text string can be edited by the user.

The information regarding the LSA identification is contained on the SIM card in the LSA descriptor files, more precisely in the byte 'LSA descriptor type and number' (see table below, from 3GPP TS 11.11, subclause 10.4.1.3).
Residing under DFSoLSA, there may be several LSA Descriptor files. These EFs contains one or more records again containing LSA Descriptors forming the LSAs. LSAs can be described in four different ways. As a list of LSA IDs, as a list of LAC + CIs, as a list of CIs or as a list of LACs. As the basic elements (LSA ID, LAC + CI, CI and LAC) of the four types of lists are of different length, they can not be mixed within one record.
Different records may contain different kinds of lists within the EFs.

This EF contains the 'LSA only access indicator'. This EF shall always be allocated if DFSoLSA is present.
If the indicator is set, the network will prevent terminated and/or originated calls when the MS is camped in cells that are not included in the list of allowed LSAs in EFSLL. Emergency calls are, however, always allowed.
The EF also contains a text string which may be displayed when the MS is out of the served area(s).

20.24.1.1 Definition
|
SoLSA Cell selection is a process in which a SoLSA MS, whenever a new PLMN is selected, attempts to find a "suitable cell" of that PLMN to camp on. Two methods of searching for a "suitable cell" are possible, normal cell selection and stored list cell selection. The process ensures that the SoLSA 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. Once the SoLSA MS is camped on a cell, access to the network is allowed.
|
683b5b8a98f7b1390ddd5516ea9247a2
|
51.010-1
|
20.24.1.2 Conformance requirement
|
1. The SoLSA MS shall be able to select the strongest "suitable cell" and be able to respond to paging on that cell within 30 s of switch on. This requires a valid normal LSA SIM with PIN disabled and ideal radio conditions; 3GPP TS 05.08, subclause 6.1. And it requires a list of LSAs for the subscriber stored on the SIM; 3GPP TS 11.11, subclause 10.4.1.2.
NOTE 1: For camping on an LSA cell the LSA subscription is not necessary except for camping on an LSA exclusive access cell; 3GPP TS 03.73, subclause 11.4.2.
NOTE 2: There should be no extra delay in cell selection procedure; 3GPP TS 02.43, subclause 4.2.2.
2. There are various requirements that a cell must satisfy before a SoLSA MS can perform normal camping on it:
2.1 (i) It should be a cell of the selected PLMN.
2.2 (ii) It should not be "barred".
2.3 (iv) The radio path loss between SoLSA MS and BTS must be below a threshold set by the PLMN operator.
2.4 (v) It should not be an LSA exclusive access cell to which the SoLSA MS does not subscribe.
3GPP TS 03.22, subclause 3.2.1.
NOTE 3: Criteria (iii) is not applicable for Cell Selection.
3. Initially the SoLSA MS looks for a cell which satisfies these 5 constraints ("suitable cell") by checking cells in descending order of received signal strength. If a "suitable cell" is found, the SoLSA MS camps on it; 3GPP TS 03.22, subclause 3.2.1.
4. The SoLSA MS shall be able to calculate correctly the path loss criterion parameter C1, used for cell selection and reselection; 3GPP TS 05.08, subclause 6.4.
5. The LSA identification shall be stored on the SIM card in the LSA descriptor files.
LSAs can be described in four different ways; 3GPP TS 11.11, subclause 10.4.1.3:
- as a list of LSA IDs (3 bytes);
- as a list of LAC + CIs (4 bytes);
- as a list of CIs (2 bytes);
- as a list of LACs (2 bytes); or
- as a combination of the lists above.

|
20.24.1.3 Test purpose
|
The SoLSA MS shall be able to select a "suitable cell" according to the normal cell selection criteria. The identification of the LSA is done by using the LSA ID, the CI, the LAC or the LAC + CI.

1. The SoLSA MS shall be able to initiate emergency calls when no "suitable cells" of the selected PLMN are available, but at least one acceptable cell is available. The SoLSA MS is in limited service state.
An LSA exclusive access cell is "suitable" only if the LSA of the cell is one of the allowed LSA according to the SIM. Emergency calls are always allowed if no cells are found suitable; 3GPP TS 03.73, subclause 11.4.2.
2. When in a limited service state and if not camped on a cell, the MS shall monitor the received signal level of all RF channels within its band of operation, and search for a BCCH carrier which has C1 > 0 and which is not barred. When such a carrier is found, the MS shall camp on that cell, irrespective of the PLMN identity; 3GPP TS 05.08, subclause 6.8.
3. The MS shall perform cell reselection at least among the cells of the PLMN of the cell on which the MS has camped, according to the algorithm of 3GPP TS 03.22, except that a zero value of CELL_RESELECT_HYSTERESIS shall be used.

1. To verify that the SoLSA MS shall be able to initiate emergency calls when no "suitable cells" of selected PLMN are available, but at least one acceptable cell is available. The available cells are:
a) LSA exclusive access cells of the selected PLMN with no LSA subscription.
b) Normal LSA cell of forbidden PLMN.
2. To verify that the MS selects a cell with C1>0 and CBA = 0 when no suitable cells of the selected PLMN are available.
3. To verify that the MS, when performing cell reselection in the limited service state, uses CELL_RESELECT_HYSTERESIS = 0, 3GPP TS 05.08, subclause 6.8.

20.24.2.4.2 Test Procedure
|
a) The SS activates the carriers. The SS monitors carriers 1, 2 and 3 for RA requests for the duration of the test.
b) The SoLSA MS is switched on.
c) 60 s after switch on, an emergency call is initiated on the SoLSA MS.
d) The SS changes the CBA of carrier 1 to 0.
NOTE 1: The MS should reselect carrier 1 because it should not take into account the CRH value of 14 but use 0 instead.
e) After 350 s an emergency call is initiated on the SoLSA MS.
NOTE 2: 330 s to detect change of BCCH data on neighbour cell, 15 s to perform reselection of carrier 1 since the SoLSA MS already has a running average on carrier 1, 5 s for search of a matching LSA on SIM.

20.24.3.1 General conformance requirement
|
1. There are various requirements that a cell must satisfy before a SoLSA MS can perform normal camping on it:
i) It should be a cell of the selected PLMN.
ii) It should not be "barred".
iii) It should not be in an LA which is in the list of "forbidden LA for roaming".
iv) The radio path loss between SoLSA MS and BTS must be below a threshold set by the PLMN operator.
v) It should not be an LSA exclusive access cell to which the SoLSA MS does not subscribe.
3GPP TS 03.22, subclause 3.2.1.
2. While camped on a cell of the selected PLMN ("camped normally"), the SoLSA MS may need to select a different cell ("normal cell reselection" state). The following events trigger a cell reselection:
- The cell camped on (current serving cell) has become barred.
- 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).
- The SoLSA MS will then reselect a new cell in order to fulfil the process goal.
3GPP TS 03.22, subclause 4.5.
3. At least for every new sample or every second, whichever is the greatest, the SoLSA MS calculates the value of C1, C2 and C4 for the serving cell and the non‑serving cells. The SoLSA MS shall make a cell reselection if:
i) The path loss criterion parameter (C1) for the serving cell falls below zero for a period of 5 s.
ii) A non‑serving suitable cell (see 3GPP TS 03.22) is evaluated to be better than the serving cell for a period of 5 s. The best cell is:
- the cell with the highest value of C2 + LSA_OFFSET among those cells that have highest LSA priority among those that fulfil the criteria C4 0; or
- the cell with the highest value of C2 among all cells, if no cell fulfil the criterion C4 0.
LSA_OFFSET and LSA ID(s) are broadcast on BCCH. LSA priority is defined by the list of LSAs for the subscriber stored on the SIM. Cells with no LSA priority, e.g. non-LSA cells, are given LSA priority lower than 0. If no LSA_OFFSET parameter is broadcast, LSA_OFFSET shall be set to 0.
When evaluating the best cell, the following hysteresis values shall be subtracted from the C2 value for the neighbour cells:
- if the new cell is in the same location area: 0.
- if the new cell is in a different location area:
- CELL_RESELECT_HYSTERESIS, which is broadcast on BCCH of the serving cell.
- in case of a cell reselection occurred within the previous 15 s: 5 dB.
3GPP TS 05.08, subclause 6.6.3.
4. Cell reselection for any other reason shall take place immediately, but the cell that the SoLSA MS was camped on shall not be returned to within 5 s if another suitable cell can be found. If valid receive level averages are not available, the SoLSA MS shall wait until these values are available and then perform the cell reselection if it is still required. The SoLSA MS may accelerate the measurement procedure within the requirements in 3GPP TS 05.08, subclause 6.6.1 to minimise the cell reselection delay. 3GPP TS 05.08, subclause 6.6.3.
5. If no suitable cell is found within 10 s, the cell selection algorithm of 3GPP TS 03.22 shall be performed. Since information concerning a number of channels is already known to the SoLSA MS, it may assign high priority to measurements on the strongest carriers from which it has not previously made attempts to obtain BCCH information, and omit repeated measurements on the known ones. 3GPP TS 05.08, subclause 6.6.3.
6. At least every 5 s the MS shall calculate the value of C1 and C2 for the serving cell and re‑calculate C1 and C2 values for non serving cells (if necessary). The MS shall then check whether:
i) The path loss criterion (C1) for current serving cell falls below zero for a period of 5 s. This indicates that the path loss to the cell has become too high.
ii) The calculated value of C2 for a non‑serving suitable cell exceeds the value of C2 for the serving cell for a period of 5 s, except;
a) in the case of the new cell being in a different location area or, for a GPRS MS, in a different routing area or always for a GPRS MS in ready state in which case the C2 value for the new cell shall exceed the C2 value of the serving cell by at least CELL_RESELECT_HYSTERESIS dB as defined by the BCCH data from the current serving cell, for a period of 5 s; or
b) in case of a cell reselection occurring within the previous 15 s in which case the C2 value for the new cell shall exceed the C2 value of the serving cell by at least 5 dB for a period of 5 s.
This indicates that it is a better cell.
3GPP TS 05.08, subclause 6.6.2.
7. The SoLSA MS shall attempt to decode the full BCCH data of the serving cell at least every 30 s; 3GPP TS 05.08, subclause 6.6.1.
8. The signal strength threshold criterion parameter C4 is used to determine whether prioritised LSA cell reselection shall apply and is defined by:
C4 = A – PRIO_THR
where
A = RLA_C – RXLEV_ACCESS_MIN
and PRIO_THR is the signal threshold for applying LSA reselection. PRIO_THR is broadcast on the BCCH. If the idle mode support is disabled for the LSA (3GPP TS 11.11, subclause 10.4.1.2) or if the cell does not belong to any LSA to which the MS is subscribed or if no PRIO_THR parameter is broadcast, PRIO_THR shall be set to .
3GPP TS 05.08, subclause 6.4.
9. The LSA identification is stored on the SIM card within the descriptor file for the LSA. 3GPP TS 11.11, subclause 10.4.1.3.

20.24.3.2.1 Definition
|
While camped on a cell of the selected PLMN the SoLSA MS may need to select a different cell in order to fulfil the normal service state. This ensures that the SoLSA 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.
Idle mode support for SoLSA on the SIM card is enabled (see General Remark 1. in subclause 20.24).
