6.5.1.1.2 Conformance requirements

References: The conformance requirements covered in the current TC are specified in: TS 23.122 clauses 4.9.3.1.0 and 4.9.3.1.2. Unless otherwise stated these are Rel-16 requirements.

[TS 23.122, clause 4.9.3.1.0]

At switch on, or following recovery from lack of coverage, the MS selects the registered SNPN (if it is available) using NG-RAN access technology and if necessary (in the case of recovery from lack of coverage, see subclause 4.5.2) attempts to perform an LR.

NOTE 1: The MS in automatic SNPN selection mode can end the SNPN search procedure once the registered SNPN is found on NG-RAN access technology.

NOTE 2: An MS in automatic SNPN selection mode can use location information to determine which SNPNs can be available in its present location.

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

If there is no registered SNPN, or registration is not possible due to the SNPN being unavailable or registration failure, the MS follows the procedure in subclause 4.9.3.1.1 or subclause 4.9.3.1.2 depending on its SNPN selection mode. At switch on, the MS shall use the SNPN selection mode that was used before switching off.

NOTE 3: If successful registration is achieved, then the current serving SNPN becomes the registered SNPN and the MS does not store the previous registered SNPN for later use.

If registration is not possible on recovery from lack of coverage due to the registered SNPN being unavailable, an MS may, optionally, continue looking for the registered SNPN for an implementation dependent time.

NOTE 4: An MS registered to an SNPN should behave as described above only if one or more PDU sessions are currently active.

[TS 23.122, clause 4.9.3.1.2]

The MS indicates to the user one or more SNPNs, which are available and each of them is identified by an SNPN identity in an entry of the "list of subscriber data" in the ME. This includes SNPNs in the list of "permanently forbidden SNPNs", and the list of "temporarily forbidden SNPNs". The MS may indicate to the user whether the available SNPNs are present in the list of "temporarily forbidden SNPNs" or the list of "permanently forbidden SNPNs". The order in which those SNPNs are indicated is MS implementation specific.

For each of the SNPNs indicated to the user, the UE shall forward a human-readable network name along with the SNPN identity to the upper layers if the system information broadcasted for the SNPN includes the human-readable network name for the SNPN.

The MS shall limit its search for the SNPN to the NG-RAN access technology.

The user may select his desired SNPN and the MS then initiates registration on this SNPN using the NG-RAN access technology, the subscriber identifier and the credentials from an entry of the "list of subscriber data", with the SNPN identity matching the selected SNPN (this may take place at any time during the presentation of SNPNs).

Once the MS has registered on an SNPN selected by the user, the MS shall not automatically register on a different SNPN unless the user selects automatic SNPN selection mode.

NOTE: Emergency services are not supported in SNPN access mode.

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

References: The conformance requirements covered in the current TC are specified in: TS 23.122 clauses 4.9.3.1.0 and 4.9.3.1.1. Unless otherwise stated these are Rel-16 requirements.

[TS 23.122, clause 4.9.3.1.0]

NOTE 1: The MS in automatic SNPN selection mode can end the SNPN search procedure once the registered SNPN is found on NG-RAN access technology.

NOTE 2: An MS in automatic SNPN selection mode can use location information to determine which SNPNs can be available in its present location.

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

NOTE 3: If successful registration is achieved, then the current serving SNPN becomes the registered SNPN and the MS does not store the previous registered SNPN for later use.

NOTE 4: An MS registered to an SNPN should behave as described above only if one or more PDU sessions are currently active.

[TS 23.122, clause 4.9.3.1.0]

The MS selects another SNPN, if available, allowable, and identified by an SNPN identity in an entry of the "list of subscriber data" in the ME. If more than one SNPN are available, allowable, and each of them is identified by an SNPN identity in an entry of the "list of subscriber data" in the ME, how the MS selects one of those SNPNs is MS implementation specific.

The MS shall limit its search for the SNPN to the NG-RAN access technology.

Once the MS selects the SNPN, the MS attempts registrations on the selected SNPN using the NG-RAN access technology, the subscriber identifier and the credentials from an entry of the "list of subscriber data" with the SNPN identity matching the selected SNPN.

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

If registration cannot be achieved because no SNPNs are available, allowable, and identified by an SNPN identity in an entry of the "list of subscriber data" in the ME, the MS indicates "no service" to the user, waits until a new SNPN is available, allowable, and identified by an SNPN identity in an entry of the "list of subscriber data" in the ME and then repeats the procedure.

If there were one or more SNPNs which were available, allowable, and identified by an SNPN identity in an entry of the "list of subscriber data" in the ME but an LR failure made registration on those SNPNs unsuccessful, the MS selects one of those SNPNs again and enters a limited service state.

References: The conformance requirements covered in the current TC are specified in: TS 23.122 clauses 4.9.3.2.0 and 4.9.3.2.1. Unless otherwise stated these are Rel-16 requirements.

[TS 23.122, clause 4.9.3.2.0]

At any time the user may request the MS to initiate reselection and registration onto an available SNPN, according to the following procedures, dependent upon the SNPN selection mode of the UE.

[TS 23.122, clause 4.9.3.2.1]

The MS selects an SNPN, if available, allowable, and identified by an SNPN identity in an entry of the "list of subscriber data" in the ME in accordance with the following order:

i) an SNPN, which is available and identified by an SNPN identity in an entry of the "list of subscriber data" in the ME, excluding the previously selected SNPN. If more than one SNPN different from the previously selected SNPN are available, allowable, and each of them is identified by an SNPN identity in an entry of the "list of subscriber data" in the ME, how the MS selects one of those SNPNs is MS implementation specific.

ii) the previously selected SNPN.

The MS shall limit its search for the SNPN to the NG-RAN access technology.

The previously selected SNPN is the SNPN which the MS has selected prior to the start of the user reselection procedure.

Once the MS selects an SNPN, if the selected SNPN is other than the previously selected SNPN, the MS attempts registrations on the selected SNPN using the NG-RAN access technology, the subscriber identifier and the credentials from an entry of the "list of subscriber data" with the SNPN identity matching the selected SNPN.

NOTE: If the previously selected SNPN is selected, and registration has not been attempted on any other SNPNs, then the MS is already registered on the SNPN, and so registration is not necessary.

6.5.2.1.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 23.122, clause 4.4.3.1.2. Unless otherwise stated these are Rel-16 requirements.

[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) or stored in the ME (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 i to v, if the MS supports CAG, for each PLMN/access technology combination of NG-RAN access technology, the MS shall present to the user:

a) the PLMN/access technology combination and a list of CAG-IDs composed of one or more CAG-IDs such that for each CAG-ID:

1) there is an available CAG cell which broadcasts the CAG-ID for the PLMN; and

2) the following is true:

i) there exists an entry with the PLMN ID of the PLMN in the "CAG information list" and the CAG-ID is included in the "Allowed CAG list" of the entry; or

ii) the available CAG cell broadcasting the CAG-ID for the PLMN also broadcasts that the PLMN allows a user to manually select the CAG-ID.

For each of the presented CAG-ID, the MS may indicate to the user whether the CAG-ID is present in the "Allowed CAG list" stored in the UE; and

b) the PLMN/access technology combination without a list of CAG-IDs, if there is an available NG-RAN cell which is not a CAG cell for the PLMN. If there exists an entry for the presented PLMN in the "CAG information list" and the entry includes an "indication that the MS is only allowed to access 5GS via CAG cells", the MS may indicate to the user that the MS is only allowed to access the PLMN via CAG cells.

6.5.2.2 CAG Selection in Automatic Mode

6.5.2.2.1 Test Purpose (TP)

(1)

with { UE in Automatic network selection mode and provisioned with an empty "CAG information list” }

ensure that {

when { UE is switched on or returned to coverage, and a cell which is not a CAG cell becomes available }

then { UE selects the cell }

}

(2)

with { UE in Automatic network selection mode provisioned with a "CAG information list” }

ensure that {

when { UE is switched on or returned to coverage, and a CAG cell with a CAG-ID present in the "Allowed CAG list" becomes available }

then { UE selects the CAG cell }

}

(3)

with { UE in Automatic network selection mode provisioned with a "CAG information list” }

ensure that {

when { UE is switched on and a cell which is not a CAG cell becomes available, and there is an entry with the PLMN ID of the PLMN in the "CAG information list" but the "indication that the MS is only allowed to access 5GS via CAG cells" is not included in the entry }

then { UE selects the cell }

}

6.5.2.2.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 23.122 clauses 3.8, and 4.4.3.1.1. Unless otherwise stated these are Rel-16 requirements.

[TS 23.122, clause 3.8]

The MS may support CAG.

If the MS supports CAG, the MS can be provisioned with a "CAG information list", consisting of zero or more entries, each containing:

a) a PLMN ID;

b) an "Allowed CAG list". The "Allowed CAG list" contains zero or more CAG-IDs; and

c) an optional "indication that the MS is only allowed to access 5GS via CAG cells".

The "CAG information list" is stored in the ME.

NOTE: When the UE is registering or registered to a PLMN other than the HPLMN or EHPLMN, then the HPLMN will send a "CAG information list" consisting of CAG subscription information related to the serving PLMN only. When the UE is registering or registered to the HPLMN or EHPLMN then the HPLMN or EHPLMN can send CAG subscription information related to any PLMN in the "CAG information list".

If the MS supports CAG and a PLMN is selected as described in subclause 4.4.3.1.1, the automatic CAG selection is performed as part of subclause 4.4.3.1.1.

If the MS supports CAG and a PLMN is selected as described in subclause 4.4.3.1.2, the manual CAG selection is performed as part of subclause 4.4.3.1.2.

The NAS shall provide the AS with a "CAG information list", if available. If the contents of the "CAG information list" have changed, the NAS shall provide an updated "CAG information list" to the AS.

[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) or stored in the ME (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.

When following the above procedure the following requirements apply:

…

m) In i to v, if the MS supports CAG and:

1) is provisioned with a non-empty "CAG information list", the MS shall consider a PLMN indicated by an NG-RAN cell only if:

A) the cell is a CAG cell and broadcasts a CAG-ID for the PLMN such that there exists an entry with the PLMN ID of the PLMN in the "CAG information list" and the CAG-ID is included in the "Allowed CAG list" of the entry; or

B) the cell is not a CAG cell and:

– there is no entry with the PLMN ID of the PLMN in the "CAG information list"; or

– there exists an entry with the PLMN ID of the PLMN in the "CAG information list" but the "indication that the MS is only allowed to access 5GS via CAG cells" is not included in the entry; or

2) is provisioned with an empty "CAG information list" or is not provisioned with a "CAG information list", the MS shall consider a PLMN indicated by an NG-RAN cell only if the cell is not a CAG cell.

n) In i to v, if the MS only supports control plane CIoT 5GS optimization (see 3GPP TS 23.501 [62]) and the MS camps on an E-UTRA cell connected to 5GCN, which is not NB-IoT cell (see 3GPP TS 36.304 [43], 3GPP TS 36.331 [22]), the MS shall not consider PLMNs which do not advertise support of 5GS services with control plane CIoT 5GS optimization.

o) In i to v, if the MS supports CIoT 5GS optimizations, the MS shall not consider the PLMN/access technology combinations for which the MS preferred CIoT network behaviour is not advertised as supported by the PLMN/access technology combination (see 3GPP TS 24.501 [64]).

NOTE 7: As an implementation option, the MS supporting CIoT 5GS optimizations that was not able to select any PLMN according to o) can perform a second iteration of i to v with no restriction.

p) In iii, the MS shall use the PLMN/access technology combination in the "Operator Controlled PLMN Selector with Access Technology" stored in the ME, if the last received steering of roaming information contains the "list of preferred PLMN/access technology combinations"(see annex C) and is stored in the ME. Otherwise, the MS shall use the "Operator Controlled PLMN Selector with Access Technology" list retrieved from the SIM.

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

If registration cannot be achieved because no PLMNs are available and allowable, and the MS does not support access to RLOS, the MS indicates "no service" to the user, waits until a new PLMN is available and allowable and then repeats the procedure.

If there were one or more PLMNs which were available and allowable, but an LR failure made registration on those PLMNs unsuccessful or an entry in any of the lists "forbidden location areas for roaming", "forbidden tracking areas for roaming", "5GS forbidden tracking areas for roaming", "forbidden location areas for regional provision of service", "forbidden tracking areas for regional provision of service", "5GS forbidden tracking areas for regional provision of service", or "CAG information list" prevented a registration attempt, the MS selects the first such PLMN again and enters a limited service state.

with { UE in Automatic network selection mode configured with "indication that the MS is only allowed to access 5GS via CAG cells" }

ensure that {

then { UE does not select the CAG cell }

}

(3)

with { UE in Automatic network selection mode provisioned with an empty "CAG information list” }

6.5.2.3.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 23.122 clause 3.5. Unless otherwise stated these are Rel-16 requirements.

[TS 23.122, clause 3.5]

There are a number of situations in which the MS is unable to obtain normal service from a PLMN or SNPN. These include:

…

i) MS supporting CAG is camped on a CAG cell belonging to a PLMN, the CAG-ID of the CAG cell is not manually selected by the user and none of the CAG-ID(s) of the CAG cell are present in the "Allowed CAG list" associated with that PLMN in the "CAG information list";

j) MS supporting CAG is camped on a non-CAG cell belonging to a PLMN, the PLMN ID of the non-CAG cell without a CAG-ID is not manually selected by the user and the UE is configured with "indication that the MS is only allowed to access 5GS via CAG cells" for that PLMN in the "CAG information list"; and

k) MS supporting CAG is camped on a CAG cell belonging to a PLMN, the CAG-ID of the CAG cell is not manually selected by the user and the "CAG information list" does not contain an entry for the PLMN (e.g. because the UE is not (pre-)configured with a "CAG information list").

6.5.2.4 CAG / cell reselection / Within allowed CAG / non-CAG cell to CAG cell

6.5.2.4.1 Test Purpose (TP)

(1)

with { UE in NR RRC_IDLE state on a non-CAG cell and UE’s Allowed CAG list is not empty }

ensure that {

when { UE detects an allowed CAG cell which becomes highest ranked cell }

then { UE reselects to the CAG cell }

}

(2)

with { UE in NR RRC_IDLE state }

ensure that {

when { UE detects the cell re-selection criteria are met for the CAG cell which belongs to the higher priority frequency }

then { UE reselects the cell which belongs to the higher priority frequency }

}

6.5.2.4.2 Conformance requirements

References: The conformance requirements covered in the current TC are specified in: TS 38.304: clauses 5.2.4.2, 5.2.4.5, 5.2.4.6 and 5.2.4.10. Unless otherwise stated these are Rel-16 requirements.

[TS 38.304, clause 5.2.4.2]

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

– If the serving cell fulfils Srxlev> S_IntraSearchP and Squal > S_IntraSearchQ, 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 NR inter-frequencies and inter-RAT frequencies which are indicated in system information and for which the UE has priority provided as defined in 5.2.4.1:

– For a NR inter-frequency or inter-RAT frequency with a reselection priority higher than the reselection priority of the current NR frequency, the UE shall perform measurements of higher priority NR inter-frequency or inter-RAT frequencies according to TS 38.133 [8].

– For a NR inter-frequency with an equal or lower reselection priority than the reselection priority of the current NR frequency and for inter-RAT frequency with lower reselection priority than the reselection priority of the current NR frequency:

– If the serving cell fulfils Srxlev > S_{nonIntraSearchP} and Squal > S_{nonIntraSearchQ}, the UE may choose not to perform measurements of NR inter-frequency cells of equal or lower priority, or inter-RAT frequency cells of lower priority;

– Otherwise, the UE shall perform measurements of NR inter-frequency cells of equal or lower priority, or inter-RAT frequency cells of lower priority according to TS 38.133 [8].

– If the UE supports relaxed measurement and relaxedMeasurement is present in SIB2, the UE may further relax the needed measurements, as specified in clause 5.2.4.9.

[TS 38.304, clause 5.2.4.5]

If threshServingLowQ is broadcast in system information and more than 1 second has elapsed since the UE camped on the current serving cell, cell reselection to a cell on a higher priority NR frequency or inter-RAT frequency than the serving frequency shall be performed if:

– A cell of a higher priority NR or EUTRAN RAT/frequency fulfils Squal > Thresh_{X, HighQ} during a time interval Treselection_RAT

Otherwise, cell reselection to a cell on a higher priority NR frequency or inter-RAT frequency than the serving frequency shall be performed if:

– A cell of a higher priority RAT/ frequency fulfils Srxlev > Thresh_{X, HighP} during a time interval Treselection_RAT; and

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

Cell reselection to a cell on an equal priority NR frequency shall be based on ranking for intra-frequency cell reselection as defined in clause 5.2.4.6.

If threshServingLowQ is broadcast in system information and more than 1 second has elapsed since the UE camped on the current serving cell, cell reselection to a cell on a lower priority NR frequency or inter-RAT frequency than the serving frequency shall be performed if:

– The serving cell fulfils Squal < Thresh_{Serving, LowQ} and a cell of a lower priority NR or E-UTRAN RAT/ frequency fulfils Squal > Thresh_{X, LowQ} during a time interval Treselection_RAT.

Otherwise, cell reselection to a cell on a lower priority NR frequency or inter-RAT frequency than the serving frequency shall be performed if:

– The serving cell fulfils Srxlev < Thresh_{Serving, LowP} and a cell of a lower priority RAT/ frequency fulfils Srxlev > Thresh_{X, LowP} during a time interval Treselection_RAT; and

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

Cell reselection to a higher priority RAT/frequency shall take precedence over a lower priority RAT/frequency if multiple cells of different priorities fulfil the cell reselection criteria.

If more than one cell meets the above criteria, the UE shall reselect a cell as follows:

– If the highest-priority frequency is an NR frequency, the highest ranked cell among the cells on the highest priority frequency(ies) meeting the criteria according to clause 5.2.4.6;

– If the highest-priority frequency is from another RAT, the strongest cell among the cells on the highest priority frequency(ies) meeting the criteria of that RAT.

[TS 38.304, clause 5.2.4.6]

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

R_s = Q_meas,s +Q_hyst – Qoffset_temp

R_n = Q_meas,n -Qoffset – Qoffset_temp

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 this equals to Qoffset_frequency.

Qoffset_temp

Offset temporarily applied to a cell as specified in TS 38.331 [3].

The UE shall perform ranking of all cells that fulfil the cell selection criterion S, which is defined in 5.2.3.2.

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

If rangeToBestCell is not configured, the UE shall perform cell reselection to the highest ranked cell. If this cell is found to be not-suitable, the UE shall behave according to clause 5.2.4.4.

If rangeToBestCell is configured, then the UE shall perform cell reselection to the cell with the highest number of beams above the threshold (i.e. absThreshSS-BlocksConsolidation) among the cells whose R value is within rangeToBestCell of the R value of the highest ranked cell. If there are multiple such cells, the UE shall perform cell reselection to the highest ranked cell among them. If this cell is found to be not-suitable, the UE shall behave according to clause 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 than the serving cell according to the cell reselection criteria specified above during a time interval Treselection_RAT;

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

NOTE: If rangeToBestCell is configured but absThreshSS-BlocksConsolidation is not configured on an NR frequency, the UE considers that there is one beam above the threshold for each cell on that frequency.

[TS 38.304, clause 5.2.4.10]

In addition to normal cell reselection, a UE may optionally use an autonomous search function to detect CAG cells on serving and non-serving frequencies. However UE shall follow the cell reselection criteria based on dedicated frequency priorities and only follow the autonomous cell search result if the result fulfils also the existing cell reselection criteria based on dedicated frequency priorities.

6.5.2.6 CAG / cell reservation

6.5.2.6.1 Test Purpose (TP)

(1)

with { UE in Automatic network selection mode and provisioned with "CAG information list }

ensure that {

when { UE is switched on or returns to coverage, and a cell which is not a CAG cell with cell status “true” for other use becomes available }

then { UE does not attempt to reselect to the higher ranked cell }

}

(2)

with { UE camped normally in state NR RRC_IDLE on a CAG cell and UE’s Allowed CAG list is not empty }

ensure that {

when { a higher ranked CAG cell is found with cell status as “not barred” and “not reserved” for operator use and “true” for other use, and not “true” for future use }

then { UE does reselect to the higher ranked cell }

}

6.5.2.6.2 Conformance requirements

References: The conformance requirements covered in the current TC are specified in: TS 38.304: clauses 5.2.4.4, 5.2.4.6 and 5.3.1. Unless otherwise stated these are Rel-16 requirements.

[TS 38.304, clause 5.2.4.4]

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

If that cell and other cells have to be excluded from the candidate list, as stated in clause 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.

If the highest ranked cell or best cell according to absolute priority reselection rules is an intra-frequency or inter-frequency cell which is not suitable due to one or more of the following reasons:

– this cell belongs to a PLMN which is not indicated as being equivalent to the registered PLMN, or

– this cell is a CAG cell that belongs to a PLMN which is equivalent to the registered PLMN but with no CAG-ID that is present in the UE’s allowed CAG list being broadcasted, or

– this cell is not a CAG cell and the CAG-only indication in the UE is set, or

– this cell does not belong to a SNPN that is equal to the registered or selected SNPN of the UE in SNPN access mode,

the UE shall not consider this cell and, for operation in licensed spectrum, other cells on the same frequency as candidates for reselection for a maximum of 300 seconds.

For operation with shared spectrum channel access, when the highest ranked cell or best cell is not a candidate for reselection per the previous paragraph, the UE should continue to consider other cells on the same frequency for cell reselection, however if the second highest ranked cell on this frequency is also not suitable due to one or more of the above reasons, the UE may consider this frequency to be the lowest priority for a maximum of 300 seconds.

If the highest ranked cell or best cell according to absolute priority reselection rules is an intra-frequency or inter-frequency cell which is not suitable due to being part of the "list of 5GS forbidden TAs for roaming", the UE shall not consider this cell and other cells on the same frequency as candidates for reselection for a maximum of 300 seconds.

If the highest ranked cell or best cell according to absolute priority reselection rules is an inter-RAT cell which is not suitable due to being part of the "list of forbidden TAs for roaming" or belonging to a PLMN which is not indicated as being equivalent to the registered PLMN, the UE shall not consider this cell and other cells on the same frequency, as candidates for reselection for a maximum of 300 seconds.

If the UE enters into state any cell selection, any limitation shall be removed. If the UE is redirected under NR control to a frequency for which the timer is running, the limitation(s) on that frequency shall be removed.

[TS 38.304, clause 5.2.4.6]

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

R_s = Q_meas,s +Q_hyst – Qoffset_temp

R_n = Q_meas,n -Qoffset – Qoffset_temp

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 this equals to Qoffset_frequency.

Qoffset_temp

Offset temporarily applied to a cell as specified in TS 38.331 [3].

The UE shall perform ranking of all cells that fulfil the cell selection criterion S, which is defined in 5.2.3.2.

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

If rangeToBestCell is not configured, the UE shall perform cell reselection to the highest ranked 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 than the serving cell according to the cell reselection criteria specified above during a time interval Treselection_RAT;

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

[TS 38.304, clause 5.3.1]

Cell status and cell reservations are indicated in the MIB or SIB1 message as specified in TS 38.331 [3] by means of following fields:

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

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

– cellReservedForOtherUse (IE type: "true")
Indicated in SIB1 message. In case of multiple PLMNs indicated in SIB1, this field is common for all PLMNs.

– cellReservedForFutureUse (IE type: "true")
Indicated in SIB1 message. In case of multiple PLMNs or NPNs indicated in SIB1, this field is common for all PLMNs and NPNs.

NOTE 0: IAB-MT ignores the cellBarred, cellReservedForOperatorUse, cellReservedForFutureUse and intraFreqReselection (i.e. treats intraFreqReselection as if it was set to allowed) as defined in TS 38.331 [3]. IAB-MT also ignores cellReservedForOtherUse for cell barring determination (i.e. NPN capable IAB-MT considers cellReservedForOtherUse for determination of an NPN-only cell) as defined in TS 38.331 [3].

– iab-Support (IE type: "true")
Indicated in SIB1 message. In case of multiple PLMNs or NPNs indicated in SIB1, this field is specified per PLMN or per SNPN.

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

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

When cell broadcasts any CAG-IDs or NIDs and the cell status is indicated as "not barred" and "not reserved" for operator use and "true" for other use, and not "true" for future use:

– All NPN-capable UEs shall treat this cell as candidate during the cell selection and cell reselection procedures, other UEs shall treat this cell as if cell status is "barred".

When cell status is indicated as "true" for other use, and either cell does not broadcast any CAG-IDs or NIDs or does not broadcast any CAG-IDs and the UE is not operating in SNPN Access Mode,

– The UE shall treat this cell as if cell status is "barred".

When cell status is indicated as "true" for future use,

– The UE shall treat this cell as if cell status is "barred".

When cell status is indicated as "not barred" and "reserved" for operator use for any PLMN/SNPN and not "true" for other use and not "true" for future use,

– UEs assigned to Access Identity 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 Access Identity 11 or 15 shall treat this cell as candidate during the cell selection and reselection procedures if the field cellReservedForOperatorUse for selected/registered SNPN is set to "reserved".

– UEs assigned to an Access Identity 0, 1, 2 and 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/SNPN or the selected PLMN/SNPN.

NOTE 1: Access Identities 11, 15 are only valid for use in the HPLMN/ EHPLMN; Access Identities 12, 13, 14 are only valid for use in the home country as specified in TS 22.261 [12].

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 MIB:

– 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 field intraFreqReselection in MIB message is set to "allowed":

– the UE may select another cell on the same frequency if re-selection criteria are fulfilled;

– If the cell is to be treated as if the cell status is "barred" due to being unable to acquire the SIB1:

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

– else:

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

– If the field intraFreqReselection in MIB message is set to "not allowed":

– If the cell is to be treated as if the cell status is "barred" due to being unable to acquire the SIB1:

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

– If the cell operates in licensed spectrum:

– the UE shall not re-select to another cell on the same frequency as the barred cell and exclude such cell(s) as candidate(s) for cell selection/reselection for 300 seconds;

– else:

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

– else:

– If the cell operates in licensed spectrum, or if this cell belongs to a PLMN which is indicated as being equivalent to the registered PLMN or the selected PLMN of the UE, or if this cell belongs to the registered SNPN or the selected SNPN of the UE:

– the UE shall not re-select to another cell on the same frequency as the barred cell and exclude such cell(s) as candidate(s) for cell selection/reselection for 300 seconds;

– else:

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

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

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

NOTE 2: If barring of a cell is triggered by the condition of trackingAreaCode not being provided, as specified in TS 38.331 [3], the barring only applies to this PLMN and the UE can re-evaluate the barring condition again due to selection of another PLMN.
