20.21.19.4.2 Test procedure
|
a) The SS activates the carriers. No paging messages are transmitted on carrier 1 or carrier 2.
b) The MS is switched on.
c) In response to the MS access for IMSI attach, the SS allocates a combined SDDCH/4, accepts the IMSI attach procedure and then releases the link. After 0,5 s but within 1 s of transmitting the UA frame on completion of the IMSI attach procedure, the SS transmits a single PAGING REQUEST in the appropriate paging block of the MS on carrier 1.
d) When the MS responds to paging, the SS establishes a call on a traffic channel.
e) The SS increases the level of carrier 2 to 63 dBmV emf().
f) After 10 s the SS performs a handover to another TCH, with the parameters of carrier 2 indicated in the CELL DESCRIPTION information element of the HANDOVER COMMAND message.
g) After a further 10 s, the SS clears down the call. After 0,5 s but within 1 second of transmitting the UA frame, the SS transmits a single PAGING REQUEST on carrier 2 in the appropriate paging block of the MS.

20.22 GPRS Cell Selection and Reselection
|
The absolute accuracy of the 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, C31, C32 values and 0.
The relative accuracy of the 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 and C31 and C32 values on different carriers.
NOTE 1: The accuracy of MS signal level measurements is specified in 3GPP TS 05.08/45.008. 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 05.08/45.008 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.
The MS shall perform cell re-selection according to the idle mode procedures defined in clause 6 of 3GPP TS 05.08/45.008 and therefore tests defined in clause 20 of TS 51.010 apply.
The support of GPRS shall be indicated in SYSTEM INFORMATION TYPE 3 message. In addition, the support of GPRS shall be indicated in either SYSTEM INFORMATION TYPE 4 or SYSTEM INFORMATION TYPE 7 and 8 messages. If GPRS is supported, SYSTEM INFORMATION TYPE 13 message shall be sent. SI 13 message shall not be sent if GPRS is not supported (3GPP TS 04.08 / 3GPP TS 44.018, subclause 3.2.2.1). Additional requirements for the broadcast of system information in a cell supporting GPRS are specified in 3GPP TS 04.60/44.060. The GPRS support is indicated by the presence of the field GPRS Indicator in the SI Rest Octets (3GPP TS 04.08 / 3GPP TS 44.018, subclauses 10.5.2.34; 10.5.2.35, 10.5.2.36 and 10.5.2.37).
The following definitions are applicable to tests 20.22.1 to 20.22.33
- Carrier X supports GPRS : the SS includes the field GPRS Indicator in SI 3 Rest Octets and in SI 4 Rest Octets.
- The SS enables GPRS on carrier X : the SS starts including the field GPRS Indicator in SI 3 Rest Octets and in SI 4 Rest Octets.
- The SS disables GPRS on carrier X : the SS stops including the field GPRS Indicator in SI 3 Rest Octets and in SI 4 Rest Octets.
- Carrier X supports EC-GSM-IoT : the SS indicates the support of EC-GSM-IoT with the use of EC-SCH.
Unless otherwise stated in the method of test, in all of the tests of this subclause:
- The SIM is in the idle updated state in the default registration area with a TMSI and PTMSI assigned at the beginning of each test.
- By default idle paging is transmitted on the PCH according to 3GPP TS 04.08 / 3GPP TS 44.018, subclause 3.2.2.2.
- Where MS paging is specified within a test, TMSI is to be used on CCCH
- The Scheduling of System Information should be such that a complete set of consistent SI messages, including SI13 were applicable, can be decoded within 8 multiframes (8 51 frames).
- The Scheduling of EC System Information should be such that a complete set of consistent EC SI messages, can be decoded within 24 51-multiframes (3 x 8 51 frames).
- The MS is configured to automatically attach to GPRS at switch on by using the PICS/PIXIT Statement "Automatic GPRS attach procedure at switch on or power on Yes/No" as in GPRS Attach procedure tests (see subclause 44.2.1). For MS that does attach at power on, the SS shall accept access request with cause 'one phase access' in determining test verdict where applicable.
- The network simulation settings as specified in section 40 shall be applied unless otherwise stated in section 20.22.

|
20.22.8.1 Definition
|
Cell selection is a process in which an 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 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. The support of GPRS is not a condition to select a cell. Once the MS is camped on a cell, access to the network is allowed.

20.22.8.2 Conformance requirement
|
1. … the MS shall be able to select the correct (fourth strongest) cell and be able to respond to paging on that cell within 30 seconds of switch on, when the three strongest cells are not suitable. This assumes a valid SIM with PIN disabled and ideal radio conditions
3GPP TS 05.08 / 3GPP TS 45.008, subclause 6.1.
2. There are various requirements that a cell must satisfy before an 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" (see subclause 3.5.1);
2.3 (iii) It should not be in an LA which is in the list of "forbidden LAs for roaming";
2.4 (iv) The radio path loss between MS and BTS must be below a threshold set by the PLMN operator. This is estimated as shown in subclause 3.6. 3GPP TS 03.22, subclause 3.2.1.
NOTE: Criteria 2.3 (iii) is not applicable for Cell Selection.
3. Initially the MS looks for a cell which satisfies these 4 constraints ("suitable cell") by checking cells in descending order of received signal strength. If a suitable cell is found, the MS camps on it, 3GPP TS 03.22, subclause 3.2.1.
4. The 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.

20.22.8.3 Test purpose
|
1. To verify that the MS meets conformance requirement 1. even when one of the other cells supports GPRS.
2. To verify that:
2.1 The MS does not select a cell of a PLMN, which is not the selected PLMN.
2.2 The MS does not select a cell which is "barred".
2.4 The MS does not select a cell with C1 < 0.
3. To verify that the MS selects suitable cells in descending order of received signal strength.
4. To verify that the MS does not select a cell with C1 < 0.

20.22.9.1 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. The target cell should be reselected despite it does not support GPRS.

|

|
20.22.9.2 Conformance requirement
|
1. While camped on a cell of the selected PLMN ("camped normally"), the MS may need to select a different cell ("normal cell reselection" state). The following events trigger a cell reselection:
1.1 (iii) The cell camped on (current serving cell) has become barred.
1.2 (iv) 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 MS will then reselect a new cell in order to fulfil the process goal.; 3GPP TS 03.22, subclause 4.5.
NOTE 1: Criterion (i) is tested in subclause 20.8 (Cell reselection when C1(serving cell) < 0 for 5 s).
NOTE 2: Criterion (ii) is tested subclause 20.16 (Downlink signalling failure).
NOTE 3: Criterion (v) is tested in subclause 20.6 (Cell reselection timings).
2. There are various requirements that a cell must satisfy before an MS can perform normal camping on it:
2.1 (ii) It should not be "barred".
2.2 (iv) The radio path loss between MS and BTS must be below a threshold set by the PLMN operator. 3GPP TS 03.22, subclause 3.2.1.
NOTE 4: Criterion (i) is not relevant for cell reselection and for cell selection it is tested in subclause 20.1.
NOTE 5: Criterion (iv) refers to the C1 parameter.
3. 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.
4. At least every 5 s the MS shall calculate the value of C1 and C2 for the serving cell and recalculate 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 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 seconds. This indicates that it is a better cell. 3GPP TS 05.08, subclause 6.6.2.
5. The 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.

2.2 The MS does not reselect a cell which has a C1 < 0.
2.3 The MS does reselect a cell even if does not support GPRS.
2.4 The MS keeps camping on the serving cell despite it does not support GPRS and there is a non‑serving suitable cell with a lower C2 that supports GPRS.
2.5 The MS does not attempt to attach to GPRS when camping on a cell that does not support GPRS despite there is a non‑serving suitable cell with a lower C2 that supports GPRS.
3. To verify that the MS takes into account the CELL_RESELECT_HYSTERESIS parameter when reselecting a cell in a different location area or if MS in Ready State, whether this cell supports GPRS or not.

The MS is required to perform the following measurements to ensure that the path loss criterion to the serving cell is acceptable.(3GPP TS 05.08 subclause 6.6.2).
At least every 5s 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:
1) 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.
2) The calculated value of C2 for 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 new cell being in a different location area, 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_HYSTERSIS 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 5dB for a period of 5 s.
This indicates that it is a better cell.
A cell update takes place when the MS enters a new cell inside the current RA and the MS is in READY state. If the RA has changed, a routeing area update is executed instead of a cell update (3GPP TS 03.60 subclause 6.9.11).

20.22.22.2 Conformance requirement
|
At least for every new sample or every second, whichever is the greatest, the MS shall update RLA_P and calculate the value of C1, C31 and C32 for the serving cell and the non-serving cells; 3GPP TS 05.08, subclause 10.1.2. The MS shall make a cell re-selection if:
a. The path loss criterion parameter (C1) for the serving cell falls below zero.
b. A non-serving suitable cell (see 3GPP TS 03.22) is evaluated to be better than the serving cell. The best cell is the cell with highest value of C32 among:
- Those cells that have the highest PRIORITY_CLASS among those that fulfill the criterion C31 0; or
- All cells, if no cells fulfill the criterion C31 0;
- If the parameter C32_QUAL is set, positive GRPS_RESELECT_OFFSET values shall be only be applied to the neighbor cell with the highest RLA_P value of those cells for which C32 is compared above.
PRIORITY_CLASS and C32_QUAL are broadcast on PBCCH of the serving cell.
When evaluating the best cell, the following hysteresis values shall be subtracted from the C32 value for the neighbor cells:
- in standby state, if the new cell is in the same routing area: 0.
- in ready state, if the new cell is in the same routing area:
- GPRS_CELL_RESELECT_HYSTERESIS.If the parameter C31_HYST is set;
- GPRS_CELL_RESELECT_HYSTERESIS shall also be subtracted from the C31 value for the neighbour cells.
- in standby or ready state, if the new cell is in a different routing area:
- RA_RESELECT_HYSTERESIS.
- in case of a cell re-selection occurred within the previous 15 s: 5 dB.
- GPRS_CELL_RESELECT_HYSTERESIS,C31_HYST and RA_RESELECT_HYSTERESIS are broadcast on PBCCH of the serving cell.
The cell re-selection procedures defined in subclauses 10.1.1 to 10.1.3 (of 3GPP TS 05.08) apply to the MS attached to GPRS if a PBCCH exists in the serving cell. These procedures shall also apply for cells for which GPRS cell re‑selection parameters are provided to the MS in a Packet Cell Change Order or Packet Measurement Order message. Otherwise the MS shall perform cell re-selection according to the idle mode procedures defined in clause 6 of 3GPP TS 05.08.

20.22.22.3 Test purpose
|
To verify that the MS reselects to the correct cell by calculating C32 correctly when one of the cells is in a different routing area. When the MS is in the Standby or ready state, on triggering of a reselection, when it considers a suitable cell which happens to be in a different Routing Area, the C32 value of the new cell must be reduced by RARH for comparison.

NOTE 1: The BA(BCCH) list only contains the ARFCNs of the carriers used during the test.
NOTE 2: The value of RXLEV_ACCESS_MIN is obtained from the SI messages for reselection. NOTE 3: When a neighbouring cell belongs to a different RA, RARH value is deduced from its C32 value during reselection, if the MS is in Standby or Ready state. In absence of PBCCH, when RARH is not available, CRH (from SI messages on BCCH) is used instead (3GPP TS 05.08 subclause 10.1.1).
NOTE 3: GPRS reselection parameters for carrier 1 shall be converted from the idle mode cell reselection parameters received on System Information 4 on BCCH according to 3GPP TS 05.08 table 3a.

20.22.29.1 Conformance requirement
|
For a multi-RAT MS, cells or frequencies with other radio access technologies may be included in 3G Cell Reselection list (see 3GPP TS 04.18). The network controls the measurements for reselection of these cells by the parameter Qsearch_I broadcast on BCCH. Qsearch_I defines a threshold and also indicates whether these measurements shall be performed when RLA_C (see subclause 6.6.1) of the serving cell is below or above the threshold. These measurements may be performed less frequently than measurements of GSM cells as described in subclause 6.6.1, in order to conserve MS power.
The MS shall be able to identify and select a new best UTRAN cell on a frequency, which is part of the 3G Cell Reselection list, within 30 seconds after it has been activated under the condition that there is only one UTRAN frequency in the list and under good radio conditions. For test purposes the following radio conditions can be used: Serving GSM cell at RXLEV= -70 dBm, with 6 GSM neighbours at RXLEV= -75 dBm. Then either an UTRAN FDD neighbour cell or an UTRAN TDD neighbour cell is switched on. The radio conditions for the UTRAN FDD cell are as follows (see TS 25.101 for definitions):

The allowed time is increased by 30 seconds for each additional UTRAN frequency in the 3G Cell Reselection list. However, multiple UTRAN cells on the same frequency in the list do not increase the allowed time.
A multi-RAT MS shall be able to monitor 64 UTRAN cells, divided into (depending on the MS capability):
- FDD cells on up to 3 FDD frequencies, with a maximum of 32 cells per frequency; and/or
- TDD cells on up to 3 TDD frequencies with a maximum of 32 cells per frequency.
The MS shall attempt to read and store UTRAN predefined configurations using the rules defined in 3GPP TS 25.331 with the following exceptions:
- The MS shall build a list of at most 16 predefined configurations, read from the BCCH of the identified UTRAN cells of equivalent PLMNs.
- After PLMN selection (see 3GPP TS 23.122), the MS shall delete any old list of predefined configurations and as soon as possible attempt to read the predefined configurations from one identified UTRAN cell of the selected PLMN or of an equivalent PLMN.
- The MS shall attempt to update the list of predefined configurations every 60 minutes.
In case of a conflict with GSM tasks, the GSM tasks take precedence.
NOTE: Instead of reading new predefined configurations from a PLMN, the MS may use previously received predefined configurations for that PLMN according to the rules in 3GPP TS 25.331.
The MS shall report the list of predefined configurations in the UTRAN CLASSMARK CHANGE message (see 3GPP TS 04.18).

• Support of UTRAN TDD (TSPC_Type_UTRAN_TDD)
Foreseen final state of the MS
- MS is in Packet Idle mode.
Test procedure
The GSM/GPRS cell operates in NC0. The MS is brought into downlink packet transfer mode on GSM carrier. The SS sends a PACKET MEASUREMENT ORDER message, setting Qsearch_P to “Never”. The SS activates UTRAN carrier with higher RF signal strength than GSM carrier. The MS shall stay camping in the cell of Carrier 1. During the transfer, the SS sends a PACKET MEASUREMENT ORDER message, setting 3G search to “Always”.
The GPRS 3G Cell Reselection list includes UTRAN frequencies.
If the UTRAN operates in FDD mode, the MS then reselects (see TS 25.304) a UTRAN FDD cell when its measured RSCP value exceeds the value of RLA_P for the serving cell by the value FDD_GPRS_Qoffset for a period of 5 seconds and the UTRAN cell measured Ec/No value is equal or greater than the value FDD_Qmin, where FDD_Qmin and FDD_Qoffset are broadcast on BCCH of the serving cell.
If the UTRAN operates in TDD mode, the MS then reselects a UTRAN TDD cell when its measured RSCP value exceeds the value of TDD_Qoffset.
The UTRAN neighbour cell is suitable and the parameters required to determine if it is suitable are broadcast on BCCH of the UTRAN cell.

NOTE 1: All cells support GPRS. Network Control Reporting information is broadcasted using the SI2 Quater.
NOTE 2: Cell C is not a part of BA(GPRS) - i.e. NC frequency List of PMO and BA(BCCH) -, Cell B is part of BA(GPRS)on Cell A
Procedure
a) The SS activates all Cells.
b) MS is switched ON.
c) The MS shall complete the GPRS attach procedure on Cell A(Ready Timer deactivated).
d) SS increases the signal strength of Cell C to -50dBm.
e) SS receives measurement report till the measurements of Cell B are included in it.
f) SS sends a PACKET MEASUREMENT ORDER changing the NC mode to NC0.
g) SS reduces the signal strength of Cell A to -95 dBm.

20.22.30.1.4 Test Requirements
|
1) MS shall camp on Cell A after step b) and initiate the attach procedure.
2) In step e), MS should not include the measurements of Cell C in the measurement reports. This is checked up to Max{5s, 5 consecutive paging blocks of that MS} to ensure the MS has completed the running average measurements of the neighbour cells.
3) In step f), SS checks that the MS stays on Cell A, and does not reselect to Cell C, even though Cell C is better than Cell A for a period of 5s + Max{5s, 5 consecutive paging blocks of the MS}.
4) In step g), the MS shall respond on Cell B even though the Cell C is better than Cell B for reselection, as Cell C is not a part of BA(GPRS). The response should be within the time given in the note below.
NOTE: Time allowed includes Max{5s, 5 consecutive paging blocks of the MS} for MS to determine C32 of Cell C is greater than Cell A, 2 seconds to decode BCCH and 1 sec for re-selection.
