22.2.1.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 23.122 clauses 4.4.3.1, 4.4.3.1.1 and 4.4.3.3. Unless otherwise stated these are Rel-13 requirements.

[TS 23.122, clause 4.4.3.1]

At switch on, or following recovery from lack of coverage, the MS selects the registered PLMN or equivalent PLMN (if it is available) using all access technologies that the MS is capable of and if necessary (in the case of recovery from lack of coverage, see clause 4.5.2) attempts to perform a Location Registration.

…

If successful registration is achieved, the MS indicates the selected PLMN.

If there is no registered PLMN, or if registration is not possible due to the PLMN being unavailable or registration failure, the MS follows one of the following two procedures depending on its PLMN selection operating mode. At switch on, if the MS provides the optional feature of user preferred PLMN selection operating mode at switch on then this operating mode shall be used.

…

NOTE 1: If successful registration is achieved, then the current serving PLMN becomes the registered PLMN and the MS does not store the previous registered PLMN for later use.

[TS 23.122, clause 4.4.3.1.1]

The MS selects and attempts registration on other PLMN/access technology combinations, if available and allowable, in the following order:

i) either the HPLMN (if the EHPLMN list is not present or is empty) or the highest priority EHPLMN that is available (if the EHPLMN list is present) ;

ii) each PLMN/access technology combination in the "User Controlled PLMN Selector with Access Technology" data file in the SIM (in priority order);

iii) each PLMN/access technology combination in the "Operator Controlled PLMN Selector with Access Technology" data file in the SIM (in priority order);

iv) …

v) …

When following the above procedure the following requirements apply:

a) …

b) …

c) In ii and iii, the MS should limit its search for the PLMN to the access technology or access technologies associated with the PLMN in the appropriate PLMN Selector with Access Technology list (User Controlled or Operator Controlled selector list). An MS using a SIM without access technology information storage (i.e. the "User Controlled PLMN Selector with Access Technology" and the "Operator Controlled PLMN Selector with Access Technology" data files are not present) shall instead use the "PLMN Selector" data file, for each PLMN in the "PLMN Selector" data file, the MS shall search for all access technologies it is capable of and shall assume GSM access technology as the highest priority radio access technology.

d) …

e) …

f) In i, the MS shall search for all access technologies it is capable of. No priority is defined for the preferred access technology and the priority is an implementation issue, but "HPLMN Selector with Access Technology" data file on the SIM may be used to optimise the procedure.

g) …

h) …

NOTE 1: …

NOTE 2: …

NOTE 3: High quality signal is defined in the appropriate AS specification.

If successful registration is achieved, the MS indicates the selected PLMN.

[TS 23.122, clause 4.4.3.3]

If the MS is in a VPLMN, the MS shall periodically attempt to obtain service on its HPLMN (if the EHPLMN list is not present or is empty) or one of its EHPLMNs (if the EHPLMN list is present) or a higher priority PLMN/access technology combinations listed in "user controlled PLMN selector" or "operator controlled PLMN selector" by scanning in accordance with the requirements that are applicable to i), ii) and iii) as defined in the Automatic Network Selection Mode in subclause 4.4.3.1.1. In the case that the mobile has a stored "Equivalent PLMNs" list the mobile shall only select a PLMN if it is of a higher priority than those of the same country as the current serving PLMN which are stored in the "Equivalent PLMNs" list. For this purpose, a value of timer T may be stored in the SIM. The interpretation of the stored value depends on the modes supported by the MS:

– For an MS that does not only support any of the following or a combination of NB-S1 mode or GERAN EC-GSM-IoT or Category M1 of E-UTRAN enhanced-MTC mode (as defined in 3GPP TS 36.306 [13]): T is either in the range 6 minutes to 8 hours in 6 minute steps or it indicates that no periodic attempts shall be made. If no value for T is stored in the SIM, a default value of 60 minutes is used for T.

– For an MS that only supports any of the following or a combination of NB-S1 mode or GERAN EC-GSM-IoT or Category M1 of E-UTRAN enhanced-MTC mode (as defined in 3GPP TS 36.306 [13]): T is either in the range 2 hours to 240 hours, using 2 hour steps from 2 hours to 80 hours and 4 hour steps from 84 hours to 240 hours, or it indicates that no periodic attempts shall be made. If no value for T is stored in the SIM, a default value of 72 hours is used.

If the MS is configured with the MinimumPeriodicSearchTimer as specified in 3GPP TS 24.368 [50] or 3GPP TS 31.102 [40], the MS shall not use a value for T that is less than the MinimumPeriodicSearchTimer. If the value stored in the SIM, or the default value for T (when no value is stored in the SIM), is less than the MinimumPeriodicSearchTimer, then T shall be set to the MinimumPeriodicSearchTimer.

The MS can be configured for Fast First Higher Priority PLMN search as specified in 3GPP TS 31.102 [40] or 3GPP TS 24.368 [50]. Fast First Higher Priority PLMN search is enabled if the corresponding configuration parameter is present and set to enabled. Otherwise, Fast First Higher Priority PLMN search is disabled.

The attempts to access the HPLMN or an EHPLMN or higher priority PLMN shall be as specified below:

a) The periodic attempts shall only be performed in automatic mode when the MS is roaming;

b) After switch on a period of at least 2 minutes and at most T minutes shall elapse before the first attempt is made;

c) The MS shall make the following attempts if the MS is on the VPLMN at time T after the last attempt;

d) Periodic attempts shall only be performed by the MS while in idle mode;

e) If the HPLMN (if the EHPLMN list is not present or is empty) or a EHPLMN (if the list is present) or a higher priority PLMN is not found, the MS shall remain on the VPLMN.

f) In steps i), ii) and iii) of subclause 4.4.3.1.1 the MS shall limit its attempts to access higher priority PLMN/access technology combinations to PLMN/access technology combinations of the same country as the current serving VPLMN, as defined in Annex B.

g) …

h) If the PLMN of the highest priority PLMN/access technology combination available is the current VPLMN, or one of the PLMNs in the "Equivalent PLMNs" list, the MS shall remain on the current PLMN/access technology combination.

}

(3)

with { UE in Manual network selection mode and camped normally on a cell and network has downloaded a list of equivalent PLMNs during the Attach procedure }

ensure that {

when { higher ranked cell is a cell of a PLMN in the downloaded equivalent PLMN list }

then { UE reselects to the equivalent PLMN cell. }

}

(4)

}

22.2.2.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 36.304 clause 5.1.2.2, TS 23.122 clauses 4.4.3.1 and 4.4.3.1.2.

[TS 36.304 clause 5.1.2.2]

The UE shall scan all RF channels in the E-UTRA bands according to its capabilities to find available PLMNs. On each carrier, the UE shall search for the strongest cell and read its system information, in order to find out which PLMN(s) the cell belongs to. If the UE can read one or several PLMN identities in the strongest cell, each found PLMN (see the PLMN reading in [3]) shall be reported to the NAS as a high quality PLMN (but without the RSRP value),

…

Once the UE has selected a PLMN, the cell selection procedure shall be performed in order to select a suitable cell of that PLMN to camp on.

[TS 23.122, clause 1.2]

Equivalent HPLMN list: To allow provision for multiple HPLMN codes, PLMN codes that are present within this list shall replace the HPLMN code derived from the IMSI for PLMN selection purposes. This list is stored on the USIM and is known as the EHPLMN list. The EHPLMN list may also contain the HPLMN code derived from the IMSI. If the HPLMN code derived from the IMSI is not present in the EHPLMN list then it shall be treated as a Visited PLMN for PLMN selection purposes.

…

[TS 23.122 clause 4.4.3.1]

At switch on, or following recovery from lack of coverage, the MS selects the registered PLMN or equivalent PLMN (if it is available) using all access technologies that the MS is capable of and if necessary (in the case of recovery from lack of coverage, see subclause 4.5.2) attempts to perform a Location Registration.

…

EXCEPTION: At switch on, if the MS is in manual mode and neither registered PLMN nor PLMN that is equivalent to it is available but EHPLMN is available, then instead of performing the manual network selection mode procedure of subclause 4.4.3.1.2 the MS may select and attempt registration on the highest priority EHPLMN. If the EHPLMN list is not available or is empty and the HPLMN is available, then the MS may select and attempt registration on the HPLMN. The MS shall remain in manual mode.

NOTE 1: If successful registration is achieved, then the current serving PLMN becomes the registered PLMN and the MS does not store the previous registered PLMN for later use.

…

[TS 23.122 clause 4.4.3.1.2]

The MS indicates whether there are any PLMNs, which are available using all supported access technologies. This includes PLMNs in the "forbidden PLMNs" list, "forbidden PLMNs for GPRS service" list and PLMNs which only offer services not supported by the MS. An MS which supports GSM COMPACT shall also indicate GSM COMPACT PLMNs (which use PBCCH).

If displayed, PLMNs meeting the criteria above are presented in the following order:

i)- either the HPLMN (if the EHPLMN list is not present or is empty) or, if one or more of the EHPLMNs are available then based on an optional data field on the SIM either only the highest priority available EHPLMN is to be presented to the user or all available EHPLMNs are presented to the user in priority order. If the data field is not present on the SIM, then only the highest priority available EHPLMN is presented;

ii)- PLMN/access technology combinations contained in the " User Controlled PLMN Selector with Access Technology " data file in the SIM (in priority order);

iii)- PLMN/access technology combinations contained in the "Operator Controlled PLMN Selector with Access Technology" data file in the SIM (in priority order);

iv)- other PLMN/access technology combinations with received high quality signal in random order;

v)- other PLMN/access technology combinations in order of decreasing signal quality.

In ii and iii, an MS using a SIM without access technology information storage (i.e. the "User Controlled PLMN Selector with Access Technology" and the "Operator Controlled PLMN Selector with Access Technology" data files are not present) shall instead present the PLMNs contained in the "PLMN Selector" data file in the SIM (in priority order).

In v, requirement h) in subclause 4.4.3.1.1 applies.

In i to v, requirements j), k) in subclause 4.4.3.1.1 apply.

In GSM COMPACT, the non support of voice services shall be indicated to the user.

The HPLMN may provide on the SIM additional information on the available PLMNs. If this information is provided then the MS shall indicate it to the user. This information, provided as free text may include:

– preferred partner,

– roaming agreement status,

– supported services

Furthermore, the MS may indicate whether the available PLMNs are present on the EHPLMN list, the Forbidden list, the User Controlled PLMN List or the Operator Controlled PLMN List. The MS may also indicate that the PLMN is not present on any of these lists.

The user may select his desired PLMN and the MS then initiates registration on this PLMN using the access technology chosen by the user for that PLMN or using the highest priority available access technology for that PLMN, if the associated access technologies have a priority order. (This may take place at any time during the presentation of PLMNs). For such a registration, the MS shall ignore the contents of the "forbidden location areas for roaming", "forbidden tracking areas for roaming", "forbidden location areas for regional provision of service", "forbidden tracking areas for regional provision of service", "forbidden PLMNs for GPRS service" and "forbidden PLMNs" lists.

NOTE 1: It is an MS implementation option whether to indicate access technologies to the user. If the MS does display access technologies, then the access technology selected by the user is only used for initial registration on the selected PLMN. If the MS does not display access technologies, then the access technology chosen for a particular PLMN should be the highest priority available access technology for that PLMN, if the associated access technologies have a priority order, and is only used for initial registration.

Once the UE has registered on a PLMN selected by the user, the UE shall not automatically register on a different PLMN unless:

i) the new PLMN is declared as an equivalent PLMN by the registered PLMN; or

ii) the user selects automatic mode.

If the user does not select a PLMN, the selected PLMN shall be the one that was selected before the PLMN selection procedure started. If no such PLMN was selected or that PLMN is no longer available, then the MS shall attempt to camp on any acceptable cell and enter the limited service state.

NOTE 2: High quality signal is defined in the appropriate AS specification.

22.2.3.1 Test Purpose (TP)

(1)

with { UE configured with “MinimumPeriodicSearchTimer“ and camped on an VPLMN cell and cells of a higher priority PLMN available }

ensure that {

when { the higher priority PLMN search timer T stored in the USIM or the default value for T is less than the MinimumPeriodicSearchTimer }

then { T shall be set to the MinimumPeriodicSearchTimer. After the first attempt to the higher priority PLMN cell is made, the UE shall not use a value for T that is less than the MinimumPeriodicSearchTimer. When the T expires the UE selects and camps on a cell of the highest priority PLMN and UE attempts a location registration on the selected cell and when successfully registered indicates the selected PLMN to the user }

}

22.2.3.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 23.122 clauses 4.4.3.1 and 4.4.3.3.1. Unless otherwise stated these are Rel-13 requirements.

[TS 23.122, clause 4.4.3.1]

At switch on, or following recovery from lack of coverage, the MS selects the registered PLMN or equivalent PLMN (if
it is available) using all access technologies that the MS is capable of and if necessary (in the case of recovery from lack
of coverage, see subclause 4.5.2) attempts to perform a Location Registration.

…

If there is no registered PLMN, or if registration is not possible due to the PLMN being unavailable or registration
failure, the MS follows one of the following two procedures depending on its PLMN selection operating mode. At
switch on, if the MS provides the optional feature of user preferred PLMN selection operating mode at switch on then
this operating mode shall be used. Otherwise, the MS shall use the PLMN selection mode that was used before
switching off.

…

NOTE 1: If successful registration is achieved, then the current serving PLMN becomes the registered PLMN and
the MS does not store the previous registered PLMN for later use.

[TS 23.122, clause 4.4.3.3.1]

If the MS is in a VPLMN, the MS shall periodically attempt to obtain service on its HPLMN (if the EHPLMN list is not present or is empty) or one of its EHPLMNs (if the EHPLMN list is present) or a higher priority PLMN/access
technology combinations listed in "user controlled PLMN selector" or "operator controlled PLMN selector" by scanning in accordance with the requirements that are applicable to i), ii) and iii) as defined in the Automatic Network Selection Mode in subclause 4.4.3.1.1. In the case that the mobile has a stored "Equivalent PLMNs" list the mobile shall only select a PLMN if it is of a higher priority than those of the same country as the current serving PLMN which are stored in the "Equivalent PLMNs" list. For this purpose, a value of timer T may be stored in the SIM. The interpretation of the stored value depends on the radio capabilities supported by the MS:

For an MS that does not only support any of the following or a combination of EC-GSM-IoT or Category M1 or Category NB1(as defined in 3GPP TS 36.306 [54]): T is either in the range 6 minutes to 8 hours in 6 minute steps or it indicates that no periodic attempts shall be made. If no value for T is stored in the SIM, a default value of 60 minutes is used for T.

For an MS that only supports any of the following or a combination of EC-GSM-IoT or Category M1 or Category NB1(as defined in 3GPP TS 36.306 [54]): T is either in the range 2 hours to 240 hours, using 2 hour steps from 2 hours to 80 hours and 4 hour steps from 84 hours to 240 hours, or it indicates that no periodic attempts shall be made. If no value for T is stored in the SIM, a default value of 72 hours is used.

22.2.4.2 Conformance requirements

References: The conformance requirements covered in the current TC are specified in: TS 36.300, clause 10.1.1.1 and TS 36.304, clause 4.1, 5.1.2.2, 5.2.1, 5.2.3.1, 5.2.3.2a , 5.2.4.6, 5.2.8a and 5.3. Unless otherwise stated these are Rel-13 requirements.1.

[TS 36.300, clause 10.1.1.1]

Cell selection:

– The UE NAS identifies a selected PLMN and equivalent PLMNs;

– The UE searches the E-UTRA frequency bands and for each carrier frequency identifies the strongest cell. It reads cell system information broadcast to identify its PLMN(s):

– The UE may search each carrier in turn ("initial cell selection") or make use of stored information to shorten the search ("stored information cell selection").

– The UE seeks to identify a suitable cell; if it is not able to identify a suitable cell it seeks to identify an acceptable cell. When a suitable cell is found or if only an acceptable cell is found it camps on that cell and commence the cell reselection procedure:

– A suitable cell is one for which the measured cell attributes satisfy the cell selection criteria; the cell PLMN is the selected PLMN, registered or an equivalent PLMN; the cell is not barred or reserved and the cell is not part of a tracking area which is in the list of "forbidden tracking areas for roaming";

– An acceptable cell is one for which the measured cell attributes satisfy the cell selection criteria and the cell is not barred;

[TS 36.304, clause 4.1]

When a UE is switched on, a public land mobile network (PLMN) is selected by NAS. For the selected PLMN, associated RAT(s) may be set [5]. The NAS shall provide a list of equivalent PLMNs, if available, that the AS shall use for cell selection and cell reselection.

With the cell selection, the UE searches for a suitable cell of the selected PLMN and chooses that cell to provide available services, further the UE shall tune to its control channel. This choosing is known as "camping on the cell".

The UE will, if necessary, then register its presence, by means of a NAS registration procedure, in the tracking area of the chosen cell and as outcome of a successful Location Registration the selected PLMN becomes the registered PLMN [5].

[TS 36.304, clause 5.1.2.2]

1. For an E-UTRAN and NB-IoT cell, the measured RSRP value shall be greater than or equal to -110 dBm.

Found PLMNs that do not satisfy the high quality criterion, but for which the UE has been able to read the PLMN identities are reported to the NAS together with the RSRP value. The quality measure reported by the UE to NAS shall be the same for each PLMN found in one cell.

…

Once the UE has selected a PLMN, the cell selection procedure shall be performed in order to select a suitable cell of that PLMN to camp on.

[TS 36.304, clause 5.2.1]

UE shall perform measurements for cell selection and reselection purposes as specified in [10].

The NAS can control the RAT(s) in which the cell selection should be performed, for instance by indicating RAT(s) associated with the selected PLMN, and by maintaining a list of forbidden registration area(s) and a list of equivalent PLMNs. The UE shall select a suitable cell based on idle mode measurements and cell selection criteria.

In order to speed up the cell selection process, stored information for several RATs may be available in the UE.

When camped on a cell, the UE shall regularly search for a better cell according to the cell reselection criteria. If a better cell is found, that cell is selected. The change of cell may imply a change of RAT. Details on performance requirements for cell reselection can be found in [10].

The NAS is informed if the cell selection and reselection results in changes in the received system information relevant for NAS.

For normal service, the UE shall camp on a suitable cell, tune to that cell’s control channel(s) so that the UE can:

– Receive system information from the PLMN; and

– receive registration area information from the PLMN, e.g., tracking area information; and

– receive other AS and NAS Information; and

– if registered:

– receive paging and notification messages from the PLMN; and

– initiate transfer to connected mode.

[TS 36.304, clause 5.2.3.1]

The UE shall use one of the following two cell selection procedures:

a) Initial Cell Selection

This procedure requires no prior knowledge of which RF channels are E-UTRA or NB-IoT carriers. The UE shall scan all RF channels in the E-UTRA bands according to its capabilities to find a suitable cell. On each carrier frequency, the UE need only search for the strongest cell. Once a suitable cell is found this cell shall be selected.

[TS 36.304, clause 5.2.3.2a]

The cell selection criterion S is fulfilled when:

Srxlev > 0 AND Squal > 0

where:

Srxlev = Q_rxlevmeas – Q_rxlevmin – Pcompensation – Qoffset_temp

Squal = Q_qualmeas – Q_qualmin – Qoffset_temp

where:

Srxlev	Cell selection RX level value (dB)
Squal	Cell selection quality value (dB)
Qoffset_temp	Offset temporarily applied to a cell as specified in [3] (dB)
Q_rxlevmeas	Measured cell RX level value (RSRP)
Q_qualmeas	Measured cell quality value (RSRQ)
Q_rxlevmin	Minimum required RX level in the cell (dBm)
Q_qualmin	Minimum required quality level in the cell (dB)
Pcompensation	If the UE supports the additionalPmax in the NS-PmaxList, if present, in SIB1, SIB3 and SIB5: max(P_EMAX1 –P_PowerClass, 0) – (min(P_EMAX2, P_PowerClass) – min(P_EMAX1, P_PowerClass)) (dB); else: max(P_EMAX1 –P_PowerClass, 0) (dB);
P_EMAX1, P_EMAX2	Maximum TX power level an UE may use when transmitting on the uplink in the cell (dBm) defined as P_EMAXin [TS 36.101]. P_EMAX1 and P_EMAX2 are obtained from the p-Max and the NS-PmaxList respectively in SIB1, SIB3 and SIB5 as specified in TS 36.331 [3].
P_PowerClass	Maximum RF output power of the UE (dBm) according to the UE power class as defined in [TS 36.101]

[TS 36.304, clause 5.2.4.6]

The cell-ranking criterion R_s for serving cell and R_n for neighbouring cells is defined by:

where:

Q_meas

RSRP measurement quantity used in cell reselections.

Qoffset

For intra-frequency: Equals to Qoffset_s,n, if Qoffset_s,n is valid, otherwise this equals to zero.

For inter-frequency: Equals to Qoffset_s,n plus Qoffset_frequency, if Qoffset_s,n is valid, otherwise and for NB-IoT this equals to Qoffset_frequency.

Qoffset_temp

Offset temporarily applied to a cell as specified in [3]

The UE shall perform ranking of all cells that fulfil the cell selection criterion S, which is defined in 5.2.3.2 (5.2.3.2a for NB-IoT), but may exclude all CSG cells that are known by the UE not to be CSG member cells.

The cells shall be ranked according to the R criteria specified above, deriving Q_meas,nand Q_meas,sand calculating the R values using averaged RSRP results.

If a cell is ranked as the best cell the UE shall perform cell reselection to that cell. If this cell is found to be not-suitable, the UE shall behave according to subclause 5.2.4.4.

In all cases, the UE shall reselect the new cell, only if the following conditions are met:

– the new cell is better ranked than the serving cell during a time interval Treselection_RAT;

– more than 1 second has elapsed since the UE camped on the current serving cell.

[TS 36.304, clause 5.2.8a]

In this state, the UE shall attempt to find a suitable cell of any PLMN to camp on and searching first for a high quality cell, as defined in subclause 5.1.2.2.

The UE, which is not camped on any cell, shall stay in this state until a suitable cell is found.

[TS 36.304, clause 5.3.1]

Cell status and cell reservations are indicated in the SystemInformationBlockType1 message (or SystemInformationBlockType1-NB message) [3] by means of two fields:

– cellBarred (IE type: "barred" or "not barred")
In case of multiple PLMNs indicated in SIB1, this field is common for all PLMNs

– cellReservedForOperatorUse (IE type: "reserved" or "not reserved")
In case of multiple PLMNs indicated in SIB1, this field is specified per PLMN.

When cell status is indicated as "not barred" and "not reserved" for operator use,

– All UEs shall treat this cell as candidate during the cell selection and cell reselection procedures.

When cell status is indicated as "not barred" and "reserved" for operator use for any PLMN,

– UEs assigned to Access Class 11 or 15 operating in their HPLMN/EHPLMN shall treat this cell as candidate during the cell selection and reselection procedures if the field cellReservedForOperatorUse for that PLMN set to “reserved”.

– UEs assigned to an Access Class in the range of 0 to 9, 12 to 14 shall behave as if the cell status is "barred" in case the cell is "reserved for operator use" for the registered PLMN or the selected PLMN.

NOTE 1: ACs 11, 15 are only valid for use in the HPLMN/ EHPLMN; ACs 12, 13, 14 are only valid for use in the home country [4].

When cell status "barred" is indicated or to be treated as if the cell status is "barred",

– The UE is not permitted to select/reselect this cell, not even for emergency calls.

– The UE shall select another cell according to the following rule:

– If the cell is to be treated as if the cell status is “barred” due to being unable to acquire the MasterInformationBlock (or MasterInformationBlock-NB), the SystemInformationBlockType1 (or SystemInformationBlockType1-NB), or the SystemInformationBlockType2 (or SystemInformationBlockType2-NB):

– the UE may exclude the barred cell as a candidate for cell selection/reselection for up to 300 seconds.

– the UE may select another cell on the same frequency if the selection criteria are fulfilled.

– else

– If the cell is a CSG cell:

– the UE may select another cell on the same frequency if the selection/reselection criteria are fulfilled.

– else

– If the field intraFreqReselection in field cellAccessRelatedInfo in SystemInformationBlockType1 (or SystemInformationBlockType1-NB) message is set to "allowed", the UE may select another cell on the same frequency if re-selection criteria are fulfilled.

– The UE shall exclude the barred cell as a candidate for cell selection/reselection for 300 seconds.

– If the field intraFreqReselection in field cellAccessRelatedInfo in SystemInformationBlockType1 (or SystemInformationBlockType1-NB) message is set to "not allowed" the UE shall not re-select a cell on the same frequency as the barred cell;

– The UE shall exclude the barred cell and the cells on the same frequency as a candidate for cell selection/reselection for 300 seconds.

The cell selection of another cell may also include a change of RAT.

22.2.5.2 Conformance requirements

References: The conformance requirements covered in the current TC are specified in: TS 36.300, clause 10.1.1.2; TS 36.304, clauses 5.2.1, 5.2.4.1, 5.2.4.2a and 5.2.4.6; TS 36.331, clause 6.7.3.1; TS 36.133, clause 4.2.2.4. Unless otherwise stated these are Rel-13 requirements.

[TS 36.300, clause 10.1.1.2]

A UE in RRC_IDLE performs cell reselection. The principles of the procedure are the following:

– The UE makes measurements of attributes of the serving and neighbour cells to enable the reselection process:

– There is no need to indicate neighbouring cells in the serving cell system information to enable the UE to search and measure a cell i.e. E-UTRAN relies on the UE to detect the neighbouring cells;

– For the search and measurement of inter-frequency neighbouring cells, only the carrier frequencies need to be indicated;

– Measurements may be omitted if the serving cell attribute fulfils particular search or measurement criteria.

– Cell reselection identifies the cell that the UE should camp on. It is based on cell reselection criteria which involves measurements of the serving and neighbour cells, except for NB-IoT:

…

For NB-IoT, cell reselection identifies the cell that the UE should camp on. It is based on cell reselection criteria which involve measurements of the serving and neighbour cells as follows:

– Intra-frequency reselection is based on ranking of cells (potentially with cell specific offsets);

– Inter-frequency reselection is based on ranking of frequencies (potentially with frequency specific offsets);

– Blind redirection supported for load balancing.

[TS 36.304, clause 5.2.1]

When camped on a cell, the UE shall regularly search for a better cell according to the cell reselection criteria. If a better cell is found, that cell is selected.

[TS 36.304, clause 5.2.4.1]

The UE shall not consider any black listed cells as candidate for cell reselection.

[TS 36.304, clause 5.2.4.2a]

When evaluating Srxlev and Squal of non-serving cells for reselection purposes, the UE shall use parameters provided by the serving cell.

Following rules are used by the UE to limit needed measurements:

– If the serving cell fulfils Srxlev> S_IntraSearchP, the UE may choose not to perform intra-frequency measurements.

– Otherwise, the UE shall perform intra-frequency measurements.

– The UE shall apply the following rules for NB-IoT inter-frequencies which are indicated in system information:

– If the serving cell fulfils Srxlev > S_{nonIntraSearchP}, the UE may choose not to perform inter-frequency measurements.

– Otherwise, the UE shall perform inter-frequency measurements.

[TS 36.304, clause 5.2.4.6]

The cell-ranking criterion R_s for serving cell and R_n for neighbouring cells is defined by:

where:

Q_meas

RSRP measurement quantity used in cell reselections.

Qoffset

For intra-frequency: Equals to Qoffset_s,n, if Qoffset_s,n is valid, otherwise this equals to zero.

For inter-frequency: Equals to Qoffset_s,n plus Qoffset_frequency, if Qoffset_s,n is valid, otherwise and for NB-IoT this equals to Qoffset_frequency.

Qoffset_temp

Offset temporarily applied to a cell as specified in [3]

The cells shall be ranked according to the R criteria specified above, deriving Q_meas,nand Q_meas,sand calculating the R values using averaged RSRP results.

If a cell is ranked as the best cell the UE shall perform cell reselection to that cell. If this cell is found to be not-suitable, the UE shall behave according to subclause 5.2.4.4.

In all cases, the UE shall reselect the new cell, only if the following conditions are met:

– the new cell is better ranked than the serving cell during a time interval Treselection_RAT;

– more than 1 second has elapsed since the UE camped on the current serving cell.

[TS 36.331, clause 6.7.3.1]

The IE SystemInformationBlockType3-NB contains cell re-selection information common for intra-frequency, and inter-frequency cell re-selection as well as intra-frequency cell re-selection information other than neighbouring cell related.

The IE SystemInformationBlockType4-NB contains neighbouring cell related information relevant only for intra-frequency cell re-selection. The IE includes cells with specific re-selection parameters.

[TS 36.133, clause 4.2.2.4]

…

The UE shall be able to evaluate whether a newly detectable inter-frequency cell meets the reselection criteria defined in TS 36.304 within Kcarrier * Tdetect,EUTRAN_Inter if at least carrier frequency information is provided for inter-frequency neighbour cells by the serving cells when Treselection = 0 provided that the reselection criteria is met by a margin of at least 5dB for reselections based on ranking or 6dB for RSRP reselections based on absolute priorities or 4dB for RSRQ reselections based on absolute priorities.

References: The conformance requirements covered in the present TC are specified in: TS 36.304, clauses 5.2.4.4 and 5.3.1.

[TS 36.304, clause 5.2.4.4]

For the highest ranked cell (including serving cell) according to cell reselection criteria specified in subclause 5.2.4.6, for the best cell according to absolute priority reselection criteria specified in subclause 5.2.4.5, the UE shall check if the access is restricted according to the rules in subclause 5.3.1.

If that cell and other cells have to be excluded from the candidate list, as stated in subclause 5.3.1, the UE shall not consider these as candidates for cell reselection. This limitation shall be removed when the highest ranked cell changes.

[TS 36.304, clause 5.3.1]

Cell status and cell reservations are indicated in the SystemInformationBlockType1 message (or SystemInformationBlockType1-NB message) [3] by means of two fields:

– cellBarred (IE type: "barred" or "not barred")
In case of multiple PLMNs indicated in SIB1, this field is common for all PLMNs

– cellReservedForOperatorUse (IE type: "reserved" or "not reserved")
In case of multiple PLMNs indicated in SIB1, this field is specified per PLMN.

When cell status is indicated as "not barred" and "not reserved" for operator use,

– All UEs shall treat this cell as candidate during the cell selection and cell reselection procedures.

When cell status is indicated as "not barred" and "reserved" for operator use for any PLMN,

– ….

….

When cell status "barred" is indicated or to be treated as if the cell status is "barred",

– The UE is not permitted to select/reselect this cell, not even for emergency calls.

– The UE shall select another cell according to the following rule:

-If the cell is a CSG cell:

…

-else

– The UE shall exclude the barred cell as a candidate for cell selection/reselection for 300 seconds.

– The UE shall exclude the barred cell and the cells on the same frequency as a candidate for cell selection/reselection for 300 seconds.

22.2.13.1 Test Purpose (TP)

(1)

with { UE in EMM-REGISTERED/RRC-IDLE and UE finds a cell which provides access by NB-IoT RAT }

ensure that {

when { systemInformationBlockType1-NB broadcast more than one TAC per PLMN }

then { UE forwards the trackingAreaList to upper layers for mobility management procedure }

}

22.2.13.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 36.331 clauses 5.2.2.7 and 6.7.2. Unless otherwise stated these are Rel-17 requirements.

[TS 36.331, clause 5.2.2.7]

Upon receiving the SystemInformationBlockType1-NB, the UE shall:

…

1> else:

2> in the remainder of the procedures use plmn-IdentityList, trackingAreaCode, trackingAreaList and cellIdentity for the cell as received in the cellAccessRelatedInfo;

1> if the frequency band indicated in the freqBandIndicator is part of the frequency bands supported by the UE; or

1> if one or more of the frequency bands indicated in the multiBandInfoList are part of the frequency bands supported by the UE:

2> forward the cellIdentity to upper layers;

2> forward the trackingAreaCode to upper layers;

2> forward the trackingAreaList to upper layers, if present;

[TS 36.331, clause 6.7.2]

trackingAreaList

A list of tracking area codes for the PLMN listed.

For the first entry in plmn-IdentityList-v1700: If this field is present, the list of tracking area codes include the tracking area code in trackingAreaCode-r13 and the tracking area codes in trackingAreaList. If this field is absent, only trackingAreaCode-r13 applies.

For other entries in plmn-IdentityList-v1700: If this field is present, the list of tracking area codes include the tracking area codes in trackingAreaList. If this field is absent, the list of tracking area codes of the preceding entry in plmn-IdentityList-v1700 applies.

The total number of signalled tracking area codes across all PLMNs cannot be more than maxTAC-NB-r17.

22.2.13.3 Test description

22.2.13.3.1 Pre-test conditions

System Simulator:

– Ncell 1 and Ncell 11 as specified in TS 36.508 clause 8.1.4.1.2 is configured.

– System information combination 9 as defined in TS 36.508 [18] clause 8.1.4.3.1.1 is used.

UE:

– The UE is in Automatic PLMN selection mode.

– The UE’s positioning engine (e.g., standalone GNSS receiver) should be enabled to allow it to acquire the position. This could be done by use of AT command, such as AT+CPOS or other commands. Otherwise, or in addition any other suitable method may also be used, e.g., GNSS simulator.

Preamble:

– The UE is in State 3-NB Registered, Idle Mode on Ncell 1 according to TS 36.508 [18].

22.2.13.3.2 Test procedure sequence

Table 22.2.13.3.2-1 shows the cell configurations used during the test. The configuration T0 indicates the initial conditions. Subsequent configurations marked “T1” is applied at the points indicated in the Main behaviour description in Table 22.2.13.3.2-2. Cell powers are chosen for a serving cell and a non-suitable “Off” cell as defined in TS 36.508 [18].
