6.3.1 CSG Selection

6.3.1.1 Manual CSG ID Selection

6.3.1.1.1 Definition

6.3.1.1.2 Conformance requirement

1. If the MS supports CSG, it is provisioned with a list of allowed CSG identities and associated PLMN identities from the USIM if the list is available in the USIM or as described in 3GPP TS 24.285 if the list is not available in the USIM. This list has zero or more entries.

– Manual mode: In this mode, the MS indicates to the user the list of available CSGs in the currently selected PLMN. The list of CSGs presented to the user is not restricted by the allowed CSG list stored in the MS. After the user makes a selection, the MS camps on a cell with the selected CSG identity and attempts to register with the associated PLMN.

2. Manual CSG ID selection enables a human user to select a CSG ID. In manual CSG ID selection the UE may scan all frequencies in the supported frequency bands and display a list of found CSG IDs or the corresponding HNB Names if broadcast by the CSG cells, and indications as to whether the found CSG IDs are contained in the UE’s Allowed CSG List. When the user selects an entry in the list, the UE selects the CSG cell with the best RF quality among the ones with same CSG ID. The UE may normally camp on the chosen cell if it is an allowed CSG cell.

During manual CSG ID selection a UE is allowed to perform Location Registration procedure on a CSG cell which CSD ID is not in the Allowed CSG List.

Based on the outcome of a Location Registration procedure initiated on a CSG cell the UE’s Allowed CSG List is updated.

The UE is allowed to not support manual CSG selection in connected mode.

3. In the UE on request of NAS, the AS shall scan all RF channels in the UTRA and E-UTRA bands according to its capabilities to find available CSG IDs. On each carrier, the UE shall at least search for the strongest cell, read its system information and report available CSG ID(s) belonging to the registered PLMN together with their “HNB name” (if broadcast) to the NAS. The search for available CSG IDs may be stopped on request of the NAS.

If NAS has selected a CSG ID and provided this selection to AS, the UE shall search for an acceptable or suitable cell belonging to the selected CSG ID to perform the location registration.

6.3.1.3 Manual CSG ID Selection across PLMNs

6.3.1.3.1 Definition

Test to verify that the UE performs the manual CSG ID selection whose CSG ID is not within the registered or selected PLMN in CSG or hybrid cells.

6.3.1.3.2 Conformance requirement

1. If the MS supports CSG, it is provisioned with an Allowed CSG list and an Operator CSG list and associated PLMN identities. Both lists can be retrieved either from the USIM if the lists are available in the USIM, or as described in 3GPP TS 24.285 [47] if the lists are not available in the USIM. These lists have zero or more entries.

– Manual mode: In this mode, the MS indicates to the user the list of available CSGs and the associated PLMNs. The list of CSGs presented to the user is not restricted by the Allowed CSG list and the Operator CSG List stored in the MS. After the user makes a selection, the MS camps on a cell with the selected CSG identity and may attempt to register with the associated PLMN.

2. Manual CSG ID selection enables a human user to select a CSG ID. In manual CSG ID selection the UE may scan all frequencies in the supported frequency bands and display a list of found CSG IDs or the corresponding HNB Names if broadcast by the CSG cells or hybrid cells, and indications as to whether the found CSG IDs are contained in the UE’s CSG white list. When the user selects an entry in the list, the UE selects any CSG cell or hybrid cell among the ones with same CSG ID. The UE may normally camp on the chosen cell if it is an allowed CSG cell or a hybrid cell.

During manual CSG ID selection a UE is allowed to perform Location Registration procedure on a CSG cell whose CSD ID is not in the CSG white list.

Based on the outcome of a Location Registration procedure initiated on a CSG cell, the UE’s CSG white list is updated.

3. In the UE on request of NAS, the AS shall scan all RF channels in the UTRA bands according to its capabilities to find available CSG IDs. On each carrier, the UE shall at least search for the strongest cell, read its system information and report available CSG ID(s) together with their “HNB name” (if broadcast) and PLMN(s) to the NAS. The search for available CSG IDs may be stopped on request of the NAS.

If NAS has selected a CSG ID and provided this selection to AS, the UE shall search for an acceptable or suitable cell belonging to the selected CSG ID to camp on.

4. If the MS has initiated the location updating procedure due to manual CSG selection and receives a LOCATION UPDATING ACCEPT message, and the MS sent the LOCATION UPDATING REQUEST message in a CSG cell, the MS shall check if the CSG ID of the cell is contained in the Allowed CSG list. If not, the MS shall add that CSG ID to the Allowed CSG list.

5. If the user selects a CSG in a PLMN that is different from the RPLMN, then the following applies:

i) The MS shall store a duplicate of the RPLMN and a duplicate of the current PLMN selection mode;

ii) The MS shall enter into Manual mode of PLMN selection in state M4 (Trying PLMN) as defined in subclause 4.3.1.2 of TS 23.122;

iii) The MS shall select the PLMN corresponding to the CSG and attempt to register on the selected CSG cell in the PLMN; and

iv) If the registration fails or the MS is no longer in the coverage of the CSG, then the MS shall return to the stored duplicate PLMN selection mode and use the stored duplicate value of RPLMN for further action.

6.3.1.4 Suitable Cell checking for reselection to the CSG Cell

6.3.1.4.1 Definition

Test to verify the UE can check whether a Cell is a CSG suitable Cell according to the CSG id and ePLMN identity.

6.3.1.4.2 Conformance requirement

1: Definitions

For the purposes of the present document, the following definitions and the definitions in [12] apply.

Absolute priority layer: A priority level can be defined for a UTRA frequency, a group of GSM frequencies or a E-UTRA frequency.

CSG whitelist: A list provided by NAS containing all the CSG identities and their associated PLMN IDs of the CSGs to which the subscriber belongs.

NOTE: This list is known as Allowed CSG List in Rel-8 Access Stratum specifications.

Acceptable Cell: A Cell that satisfies certain conditions as specified in 4.3. A UE can always attempt emergency calls on an acceptable Cell.

Available PLMN: A PLMN for which the UE has found at least one Cell and read its PLMN identity.

Barred Cell: A Cell a UE is not allowed to camp on.

Camped on a Cell: UE has completed the Cell selection/reselection process and has chosen a Cell. The UE monitors system information and (in most cases) paging information.

Camped on any Cell: UE is in idle mode and has completed the Cell selection/reselection process and has chosen a Cell irrespective of PLMN identity.

Camped on MBSFN cluster: UE has completed the MBSFN Cluster selection/reselection process and has chosen a MBSFN Cluster. The UE monitors system information and receives notifications for MBMS services and possibly receives a MBMS service.

Closed Subscriber Group (CSG): A Closed Subscriber Group identifies subscribers of an operator who are permitted to access one or more Cells of the PLMN but which have restricted access (CSG Cells).

CSG Cell: A Cell broadcasting a CSG Indicator that is set to TRUE and a specific CSG identity. All the UTRAN CSG Cells sharing the same identity and PLMN identity are identifiable as a single group for the purposes of mobility management and charging.

CSG identity: An identifier broadcast by a CSG or hybrid Cell/Cells and used by the UE to facilitate access for authorised members of the associated Closed Subscriber Group.

2. Service type in Idle and Connected Mode

This clause defines the level of service that may be provided by the network to a UE in Idle mode and Connected Mode.

The action of camping on a Cell is necessary to get access to some services. Three levels of services are defined for UE:

– Limited service (emergency calls and ETWS if supported on an acceptable Cell)

– Normal service (for public use on a suitable Cell)

– Operator service (for operators only on a reserved Cell)

Furthermore, the Cells are categorised according to which services they offer:

acceptable Cell:

An "acceptable Cell" is a Cell on which the UE may camp to obtain limited service (originate emergency calls and receive ETWS if supported). Such a Cell shall fulfil the following requirements, which is the minimum set of requirements to initiate an emergency call and to receive ETWS primary notification either with or without security in a UTRAN network:

– The Cell is not barred, see subclause 5.3.1.1;

– The Cell selection criteria are fulfilled, see subclause 5.2.3.1.2;

suitable Cell:

A "suitable Cell" is a Cell on which the UE may camp on to obtain normal service. Such a Cell shall fulfil all the following requirements.

– The Cell shall be part of either:

the selected PLMN, or:

the registered PLMN, or:

a PLMN of the Equivalent PLMN list

– For a CSG Cell, the CSG ID broadcast by the Cell is present in the CSG whitelist associated with the PLMN for which the above condition is satisfied;

According to the latest information provided by the NAS.

– The Cell is not barred, see subclause 5.3.1.1;

– The Cell is part of at least one LA that is not part of the list of "forbidden LAs for roaming" [9], which belongs to a PLMN that fulfils the first bullet above;

– The Cell selection criteria are fulfilled, see subclause 5.2.3.1.2.

If the IE “Multiple PLMN List” [4] is broadcast in the Cell, the Cell is considered to be part of all LAs with LAIs constructed from the PLMN identities in the “Multiple PLMN List” and the LAC broadcast in the Cell.

barred Cell:

A Cell is barred if it is so indicated in the system information [4].

reserved Cell:

A Cell is reserved if it is so indicated in system information [4].

Following exceptions to these definitions are applicable for UEs:

– camped on a Cell that belongs to a LA that is forbidden for regional provision of service, and during emergency calls.

– as an outcome of the manual CSG selection procedure the UE is allowed to access an acceptable Cell which fulfils the Cell selection criteria and is not barred or reserved for operator use for UEs not belonging to AC 11 or 15 and inform NAS that access is possible (for location registration procedure).

NOTE: UE is not required to support manual search and selection of CSG(s) while in RRC CONNECTED state.

A Cell that belongs to a LA that is forbidden for regional provision service ([5], [16]) is suitable but provides only limited service.

If a UE has an ongoing emergency call, all acceptable Cells of that PLMN are treated as suitable for Cell reselection for the duration of the emergency call.

suitable MBSFN cluster:

A Cell is part of an MBSFN cluster if it is indicated in system information [4]. An MBSFN cluster provides exclusively MBMS services. A suitable MBSFN cluster shall fulfil all the following requirements:

– For FDD, 3.84 Mcps TDD IMB and 3.84/7.68 Mcps TDD the MBSFN cluster shall be part of either:

the registered PLMN, or:

a PLMN of the Equivalent PLMN list

The MBSFN cluster shall be indicated as:

– providing MBSFN only service

For FDD, 3.84 Mcps TDD IMB and 3.84/7.68 Mcps TDD MBSFN cluster selection/reselection process for MBSFN clusters operating on the same frequency shall be based on reception quality. Details of the process are not specified.

3. Cell reselection with CSG Cells

Cell reselection from a non-CSG Cell to a CSG Cell

In addition to normal Cell reselection, the UE shall use an autonomous search function to detect at least previously visited allowed CSG Cells on non-serving frequencies, including inter-RAT frequencies, according to the performance requirements specified in [10], when at least one CSG ID with associated PLMN identity is included in the UE’s CSG whitelist. The UE is required to perform autonomous search function in Idle, Cell_PCH and URA_PCH states. The UE shall disable the autonomous search function for CSG Cells if the UE’s CSG whitelist is empty. If "Dedicated CSG frequency(ies) " IE is present, the UE may use the autonomous search function only on these dedicated frequencies and on the other frequencies listed in the system information.

NOTE: The UE autonomous search function, per UE implementation, determines when and/or where to search for allowed CSG Cells.

When the UE has no or an empty CSG whitelist, the UE may ignore Cells with PSC in the stored range "CSG PSC Split Information" [4] reserved for CSG Cells for intra-frequency and inter-frequency measurements and Cell re-selections.

If the UE detects a suitable CSG Cell on the same frequency it shall reselect this Cell if the concerned CSG Cell is the highest ranked Cell, according to 5.2.6.1.4.

If the UE detects a suitable CSG Cell on a different frequency it shall reselect this Cell irrespective of the Cell reselection rules applicable for the Cell the UE is currently camped on, if the detected suitable CSG Cell is the strongest Cell on that frequency. If suitable CSG Cells are detected on different frequencies and these are the strongest Cells on their frequencies, then the UE shall reselect to any one of them.

If the UE detects one or more suitable CSG Cell on another RAT, the UE shall reselect to one of them according to [18].

Cell reselection from a CSG Cell to non-CSG Cell

While camped on a suitable CSG Cell, the UE shall consider the frequency of the serving Cell to be the highest priority frequency (i.e. higher than the eight network configured values or highest HCS priority) and shall not reselect to non-CSG Cell as long as the serving Cell remains the highest ranked Cell on that frequency (This includes the case when the UE has only dedicated priorities for other frequencies but not for the current frequency, i.e. the UE does not consider the current frequency to be the lowest priority frequency according to rules in 5.2.6.1.2a and 5.2.6.1.4a). Cell reselection rules as defined in section 5.2.6.1 are applied for Cell reselection from a CSG Cell to non-CSG Cell.

Cell reselection from a CSG Cell to a CSG Cell

To search for CSG Cells not listed in the system information of the serving CSG Cell, the UE may use the autonomous search function when at least one CSG ID with associated PLMN identity is included in the UE’s CSG whitelist. The UE is required to perform autonomous search function in Idle, Cell_PCH and URA_PCH states. If "Dedicated CSG frequency(ies)" IE is present, the UE may use the autonomous search function only on dedicated frequencies and on other frequencies listed in the system information.

If the UE detects a suitable CSG Cell on the same frequency, it shall reselect to this Cell if the concerned CSG Cell is the highest ranked Cell, according to 5.2.6.1.4.

While camped on a suitable CSG Cell, the UE shall consider the frequency of the serving Cell to be the highest priority frequency (i.e. higher than the eight network configured values or highest HCS priority) as long as the serving Cell is the highest ranked Cell on that frequency (This includes the case when the UE has only dedicated priorities for other frequencies but not for the current frequency, i.e. the UE does not consider the current frequency to be the lowest priority frequency according to rules in 5.2.6.1.2a and 5.2.6.1.4a).

If the UE detects one or more suitable CSG Cell on another RAT, the UE may reselect to one of them according to [18].

For reselection to neighbour CSG Cells listed in the system information of the serving CSG Cell the UE shall apply Cell measurement rules according to 5.2.6. If the UE detects a suitable CSG Cell that is listed in the system information of the serving Cell on other frequencies, and the detected CSG Cell is the strongest Cell on that frequency, then the UE shall consider these frequencies to have a priority equal to the current frequency and shall follow Cell reselection rules according to 5.2.6.1.4 and 5.2.6.1.4a.

Cell Reselection with Hybrid Cells

In addition to normal Cell reselection rules, the UE shall use an autonomous search function to detect at least previously visited hybrid Cells whose CSG ID and associated PLMN identity is in the UE’s CSG whitelist according to the performance requirements specified in [10]. The UE shall treat detected hybrid Cells as CSG Cells if the CSG ID and associated PLMN of the hybrid Cell is in the UE’s CSG whitelist and as normal Cells otherwise.

6.3.2.3 Inter-RAT Cell Reselection / from GSM_Idle / GPRS Packet_Idle to a UTRA idle CSG cell

6.3.2.3.1 Definition

Test to verify that the UE performs the inter-RAT cell reselection from GSM_Idle/GPRS Packet_Idle to an allowed UTRA CSG cell correctly in FDD.

6.3.2.3.2 Conformance requirement

1. Inter-RAT reselection to an allowed CSG cell is supported when the UE is camped on another RAT. The UE requirements are defined in the specifications of the concerned RAT.

2. If a mobile station is a member of at least one Closed Subscriber Group, i.e. at least one CSG ID is included in the MS’s "Allowed CSG list", then, in addition to normal cell reselection, the MS shall use an autonomous search function to detect UTRAN and/or E-UTRAN CSG cells. The autonomous search function shall at least detect previously visited allowed CSG cells.

If the strongest cell which the MS has detected on a UTRAN or E-UTRAN frequency during a time interval T_reselection is a suitable CSG cell, the MS shall reselect to this cell irrespective of the cell reselection rules applicable for the cell on which the MS is currently camped.

The following requirements are valid for reselection to allowed CSG cells previously visited by the MS when the radio configuration parameters, including the carrier frequency and PSC/PCI (whichever and if it is applicable) of the CSG cell, non CSG cell and other neighbour cells, are unchanged from the most recent previous visit. The autonomous search and cell re-selection to a previously visited allowed CSG cell shall meet the performance requirements defined as follows:

– the MS shall perform search and re-selection to a previously visited allowed UTRAN FDD CSG cell, that has met the CSG cell re-selection criterion defined above, within 6 minutes in the radio conditions specified for an UTRAN FDD CSG cell in 3GPP TS 36.133 in terms of parameters for CSG inter-RAT UTRAN FDD reselection; UARFCN and PSC shall be unchanged from the most recent previous visit of the UTRAN FDD CSG cell; Serving GSM cell at RXLEV= -70 dBm, with 6 GSM neighbours at RXLEV= -75 dBm;

– the MS shall perform search and re-selection to a previously visited allowed E-UTRAN CSG cell, that has met the CSG cell re-selection criterion defined above, within 6 minutes in the radio conditions specified for an E-UTRAN CSG cell in 3GPP TS 25.133 in terms of parameters for CSG inter-RAT E-UTRA reselection; E-UARFCN and PCI shall be unchanged from the most recent previous visit of the E-UTRAN CSG cell; Serving GSM cell at RXLEV= -70 dBm, with 6 GSM neighbours at RXLEV= -75 dBm.

NOTE 4: The above performance requirements are minimum requirements defined to ensure the testability of autonomous CSG search.

3. If NAS requests AS to search for available CSG IDs, the MS shall perform the search and report the results to NAS as described in 3GPP TS 25.304 for UTRAN and as described in 3GPP TS 36.304 for E-UTRAN.

If a CSG ID is manually selected by NAS, the MS shall behave as specified in 3GPP TS 25.304 or in 3GPP TS 36.304, depending on the RAT type of the selected CSG cell.

4. If a mobile station is a member of at least one Closed Subscriber Group, i.e. at least one CSG ID is included in the MS’s "Allowed CSG list", then, in addition to normal cell reselection, the MS shall use an autonomous search function to detect UTRAN and/or E-UTRAN CSG cells. The autonomous search function shall at least detect previously visited allowed CSG cells.

Test procedure

Method C is applied.

a) The SS activates Cell 1. The UE is switched on.

b) The SS waits for random access requests from the UE.

c) The SS activates Cell 4 and Cell 5. Make UE perform manual CSG ID selection and CSG 1 is selected manually.

d) The SS waits for random access requests from the UE.

e) The SS changes the level of Cell 5 and Cell 5 is not the strongest cell on frequency f2.

f) The UE is in “automatic network selection mode” and performs the normal cell selection procedure and the SS waits for random access requests from the UE.

g) The SS changes the level of Cell 5 and Cell 5 becomes the strongest cell on frequency f2.

h) The UE performs autonomous search procedure and the SS waits for random access requests from the UE.

6.3.4.1.5 Test requirements

1) In step b, the UE shall respond and camp on Cell 1.

2) In step d, the UE shall respond and camp on Cell 5.

3) In step f, the UE shall respond and camp on Cell 1.

4) In step h, the UE shall respond and camp on Cell 5 in 6 mins.

6.3.4.2 Cell Reselection with Hybrid Cells for non-member UEs

6.3.4.2.1 Definition

Test to verify that the non-member UE detects the cell is a hybrid cell and reselects it according to normal cell reselection rules correctly.

6.3.4.2.2 Conformance requirement

1. In case the UE has CSG ID of the hybrid cell in its CSG whitelist, cell reselection procedures will be the same as for a CSG cell as described in Chapter 7.2.

For all other UEs, cell reselection procedures will utilise normal cell reselection rules.

Reference

1. TS 25.367, clause 9.2

2. TS 25.304, clause 5.2.6.5

6.3.4.2.3 Test purpose

To test the behaviour of the UE idle mode cell reselection from non-CSG cell to a hybrid Cell whose CSG ID is not in the UE’s CSG whitelist.

6.3.4.2.4 Method of test

Initial condition

Same initial conditions as in clause 6.1.2.1.4 except the following:

1. Cell 2 shall include:

– “CSG Identity” in its System Information Block type 3 with the value “000 0000 0000 0000 0000 0000 0001”.

Cell 4 shall include:

– “CSG Identity” in its System Information Block type 3 with the value “000 0000 0000 0000 0000 0000 0002”.

2. On the UE side, the Allowed CSG List and the Operator CSG List are empty.

The UE is equipped with a USIM containing default values.

Test procedure

Same test procedure as in clause 6.1.2.1.4.

6.3.4.2.5 Test requirements

Same test requirement as in clause 6.1.2.1.5.
