6.1.3.1 MBSFN only service recognition

6.1.3.1.1 Definition

Test to verify that a UE supporting both transmit and receive functions correctly distinguishes an MBSFN only mode cluster from a unicast carrier cell and performs the procedures for either MBSFN cluster selection or UTRAN unicast carrier cell selection as appropriate. The unicast carrier cell may have some (but not all) timeslots assigned to MBSFN.

6.1.3.1.2 Conformance requirement

The MS shall perform registration on the PLMN if the MS is capable of services which require registration. In both automatic and manual modes, the concept of registration on a PLMN is used. An MS successfully registers on a PLMN if:

a) The MS has found a suitable cell of the PLMN to camp on; and

b) An LR request from the MS has been accepted in the registration area of the cell on which the MS is camped (see table 1).

…

The registration on the selected PLMN and the location registration are only necessary if the MS is capable of services which require registration. Otherwise, the PLMN selection procedures are performed without registration.

…

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.

…

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

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.

…

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

…

The UE shall search for MBSFN clusters if the frequencies on which MBSFN clusters are available are not indicated in the cell that the UE is camping on for normal service if the mobile is configured to receive services via MBSFN mode. Details of the process are not specified.

For 1.28 Mcps TDD, the UE that needs receive MBMS services delivered in an MBSFN cluster may at the first step select a non MBSFN cell (i.e. a unicast cell), that the MBSFN cluster is associated with. The UE can get synchronized to the MBSFN cluster with the help of the information indicated in system information broadcast by the associated unicast cell, and receive the system information and MCCH messages in the MBSFN Special Timeslot. The details of the association between MBSFN clusters and non MBSFN cells operating in a unicast carrier are not specified. In case there are more than one MBSFN clusters indicated in system information broadcast by a unicast cell, the process of which MBSFN cluster should be selected for searching is not specified.

…

When camped on a MBSFN cluster, the UE shall perform the following tasks:

– receive the MCCH as specified in clause 8.4 and in [4];

…

If the IE "MBSFN only service" is set to TRUE the UE shall:

1> consider this cell to operate in MBSFN mode;

1> for TDD consider that all slots operate in MBSFN mode;

1> for FDD, 3.84 Mcps TDD IMB and 3.84/7.68 Mcps TDD if the UE capabilities allow the reception of MBSFN in addition to the normal UE operation the UE may receive MBMS services from this cell in accordance with requirements for selection of a cell providing only MBSFN as specified in [4]. For 1.28 Mcps TDD, if the UE capabilities allow the reception of MBSFN in addition to the normal UE operation the UE may get synchronized to the MBSFN cluster as specified in [4].

…

A cell provides MBMS service in MBSFN mode if it is indicated so in system information, see subclause 8.1.1.6.3. A UE that supports MBSFN operation may receive MBMS services via a cell operating in MBSFN mode. For FDD, 3.84 Mcps TDD IMB and 3.84/7.68 Mcps TDD in order to receive an MBMS service via a MBSFN cluster the UE shall select the MBSFN cluster as specified in [4] in addition to selecting a cell for normal camping as specified in [4]. For 1.28 Mcps TDD in order to receive an MBMS service via an MBSFN cluster the UE shall at the first step camp on a unicast cell and get the frequency and "cell parameter ID" from the system information, and then get synchronized to the MBSFN cluster operating with that frequency and "cell parameter ID". For 3.84/7.68 Mcps TDD a cell shall be considered to be operating in MBSFN mode when individual scrambling codes are assigned to all timeslots (via the IE "TDD MBSFN Information").

…

For FDD and 3.84/7.68 Mcps TDD if the IE "MBSFN frequency list" is not included in system information block 11 and if services are listed in the variable MBMS_ACTIVATED_services a UE supporting reception of MBMS service in MBSFN mode shall search for cells providing MBMS service in MBSFN mode.

For 1.28 Mcps TDD the IE "Cell parameter ID" in the IE "MBSFN frequency list" included in system information block 11 indicates the cell which is providing MBMS service in MBSFN only mode on the corresponding frequency; if the IE "Cell parameter ID" is not included in the IE "MBSFN frequency list", a UE may consider that the corresponding frequency is the secondary frequency providing MBMS service in non-MBSFN only mode of current multi-frequency cell.

…

If the variable MBMS_ACTIVATED_services is not empty, the UE shall apply the MCCH acquisition procedure upon selecting (e.g. upon power on) or re- selecting a cell supporting MBMS or an MBSFN cluster, upon change of MBMS controlling cell (e.g. due to an active set update or hard handover), upon entering UTRA from another RAT, upon release of a MBMS PTP RB for the purpose of changing transfer mode, upon return from loss of coverage and upon receiving an indication from upper layers that the set of activated services has changed.

MBSFN carrier: 1 cell, Cell 31 (PLMN1). In addition to broadcasting System Information, MCCH messages are transmitted by the SS using MBMS configuration C2 and Default1 MCCH scheduling (One ongoing session) according to subclause 11.1 or 11.2 of TS 34.108.

Unicast carrier: 1 cell, Cell 1 (PLMN1) with default configuration. The unicast carrier cell shall support FDD or TDD as appropriate to UE.

User Equipment:

The UE is switched off.

The UE is equipped with a Test-USIM containing default values. The HPLMN (MCC+MNC) of the IMSI for the USIM is set to PLMN1.

Related ICS/IXIT statements

– MBMS Broadcast services in MBSFN mode available on UE Yes/No.

– Support of transmit and receive functions available on UE Yes/No.

– Support of MBSFN receive only function available on UE Yes/No.

Test procedure

a) The UE is switched on.

b) The UE registers as specified in clause 7.2.2 of TS 34.108 on the unicast carrier Cell 1. For 3.84 Mcps TDD IMB, the UE registers on the FDD unicast carrier cell 1. On the unicast carrier Cell 1, a Location Update Accept message shall be sent on reception of a Location Updating Request message from the UE. The Location Updating Accept message shall include PLMN2 in the equivalent PLMN list. For a UE that supports both CS and PS domains or PS domain only, the Location Updating procedure could be replaced by the appropriate GMM registration procedure. In these cases, the GMM Attach Accept message shall include PLMN2 in the equivalent PLMN list.

c) The SS sends ACTIVATE RB TEST MODE on the unicast carrier and the UE responds with ACTIVATE RB TEST MODE COMPLETE. The SS then sends CLOSE UE TEST LOOP to activate RLC SDU counting on the MCCH of Cell 31.

d) The SS activates Cell 31.

e) One MBMS service from the list of services available on the Dedicated National Carrier (see TS 34.108 clause 11.2) is activated on the UE.

f) The SS transmits the SYSTEM INFORMATION BLOCK TYPE 5 message indicating the configuration of the S-CCPCH carrying MCCH within the IE " Secondary CCPCH system information MBMS". In addition to broadcasting System Information, MCCH messages are transmitted by the SS on Cell 31 using MBMS configuration C2 (one PTM session ongoing) and Default1 MCCH scheduling according to clause 11.1 or 11.2 of TS 34.108. The service is carried on a 129.6kbps RB for MTCH with 80 ms TTI as specified in clause 6.10.3.4.4.6(FDD) or a 124.4 kbps RB for MTCH with 80 ms TTI as specified in clause 6.11.7.2.2.1 (3.84 Mcps TDD IMB) or a 124 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.10.3.4.4.9 (3.84 Mcps TDD) or clause 6.11.5.4.4.9 (1.28 Mcps TDD) or clause 6.11.6.4.4.9 (7.68 Mcps TDD).

g) The UE camps on Cell 31 on the MBSFN carrier. The UE shall perform the MCCH acquisition procedure. The UE shall start receiving the p-t-m radio bearer for the ongoing activated MBMS service indicated in the MBMS UNMODIFIED SERVICES INFORMATION message according to the configuration defined in the MBMS CURRENT CELL P-T-M INFORMATION (one ongoing session corresponding to the service activated at the UE). The UE closes the test loop and starts counting successfully received RLC PDUs on the MTCH. The UE will send CLOSE UE TEST LOOP COMPLETE.

T-CPICH (IMB)	dBm/3.84MHz		-59.5	OFF	-59.5	OFF	-49.5	-49.5

a) The UE is switched on.

d) The SS activates Cell 32, Cell 34, Cell 35 and Cell 37. The SS transmits the SYSTEM INFORMATION BLOCK TYPE 5 message indicating the configuration of the S-CCPCH carrying MCCH within the IE " Secondary CCPCH system information MBMS". In addition to broadcasting System Information, MCCH messages are transmitted by the SS on all these cells using MBMS configuration C2 (one PTM session ongoing) and Default1 MCCH scheduling according to clause 11.1 or 11.2 of TS 34.108. The service is carried on a 129.6kbps RB for MTCH with 80 ms TTI as specified in clause 6.10.3.4.4.6(FDD) or a 124 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.10.3.4.4.9 (3.84 Mcps TDD) or 124.4 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.11.7.2.2.1 (3.84 Mcps TDD IMB) or clause 6.11.5.4.4.9 (1.28 Mcps TDD) or clause 6.11.6.4.4.9 (7.68 Mcps TDD).

e) After the UE is switched on in step 1 the UE starts searching for an MBSFN cell. Cell search on the MBSFN carrier is independent and not time synchronised with the message sequence on the unicast carrier. One MBMS service (National Service 1) from the list of services available is activated at this stage to ensure MBSFN cell search continues.

f) The UE camps on Cell 32 or Cell 34, recognising PLMN2 as an Equivalent PLMN to the registered PLMN on the unicast carrier. The SS transmits the SYSTEM INFORMATION BLOCK TYPE 5 message indicating the configuration of the S-CCPCH carrying MCCH within the IE " Secondary CCPCH system information MBMS". In addition to broadcasting System Information, MCCH messages are transmitted by the SS using MBMS configuration C2 (one PTM session ongoing) and Default1 MCCH scheduling according to clause 11.1 or 11.2 of TS 34.108. The service is carried on a 129.6kbps RB for MTCH with 80 ms TTI as specified in clause 6.10.3.4.4.6(FDD) or a 124 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.10.3.4.4.9 (3.84 Mcps TDD) or 124.4 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.11.7.2.2.1 (3.84 Mcps TDD IMB) or clause 6.11.5.4.4.9 (1.28 Mcps TDD) or clause 6.11.6.4.4.9 (7.68 Mcps TDD).

g) The UE shall perform the MCCH acquisition procedure. The UE shall detect the available MBMS services by acquiring the MBMS MODIFIED SERVICES INFORMATION, the MBMS UNMODIFIED SERVICES INFORMATION, the MBMS GENERAL INFORMATION, the MBMS COMMON P-T-M RB INFORMATION and the MBMS CURRENT CELL P-T-M INFORMATION.

h) The UE shall continue acquiring the above MBMS messages until it has received a consistent set of MCCH information in the same modification period. The UE shall start receiving the p-t-m radio bearer for the ongoing activated MBMS service indicated in the MBMS UNMODIFIED SERVICES INFORMATION message according to the configuration defined in the MBMS CURRENT CELL P-T-M INFORMATION (one ongoing session corresponding to the service activated at the UE). The UE closes the test loop and starts counting successfully received RLC PDUs on the MTCH. The UE will send CLOSE UE TEST LOOP COMPLETE.

i) The SS broadcasts 10 RLC SDUs on the MTCH configured on the MBMS p-t-m radio bearer for the activated service on Cell 32. The SS then broadcasts 10 RLC SDUs on the MTCH configured on the MBMS p-t-m radio bearer for the activated service on Cell 34.

j) The SS sends UE TEST LOOP MODE 3 RLC SDU COUNTER REQUEST and waits for the UE to respond with UE TEST LOOP MODE 3 RLC SDU COUNTER RESPONSE. The SS shall check that the counter returned by the UE for the MTCH of the activated service in the UE TEST LOOP MODE 3 RLC SDU COUNTER RESPONSE is > 0.

k) The SS sends OPEN UE TEST LOOP. The UE responds with OPEN UE TEST LOOP COMPLETE.

l) The SS switches off Cell 32 and Cell 34. The SS activates Cell 31 and Cell 33.

m) The SS sends CLOSE UE TEST LOOP to activate RLC SDU counting on the MTCH (Transmission identity corresponding to the activated National Service 1).

n) The UE camps on Cell 31 or Cell 33. The UE shall perform the MCCH acquisition procedure. The UE shall start receiving the p-t-m radio bearer for the ongoing activated MBMS service indicated in the MBMS UNMODIFIED SERVICES INFORMATION message according to the configuration defined in the MBMS CURRENT CELL P-T-M INFORMATION (one ongoing session corresponding to the service activated at the UE). The UE closes the test loop and starts counting successfully received RLC PDUs on the MTCH. The UE will send CLOSE UE TEST LOOP COMPLETE.

o) The SS broadcasts 10 RLC SDUs on the MTCH configured on the MBMS p-t-m radio bearer for the activated service on Cell 31. The SS then broadcasts 10 RLC SDUs on the MTCH configured on the MBMS p-t-m radio bearer for the activated service on Cell 33.

p) The SS sends UE TEST LOOP MODE 3 RLC SDU COUNTER REQUEST and waits for the UE to respond with UE TEST LOOP MODE 3 RLC SDU COUNTER RESPONSE. The SS shall check that the counter returned by the UE for the MTCH of the activated service in the UE TEST LOOP MODE 3 RLC SDU COUNTER RESPONSE is > 0.

a) The UE is switched on.

b) The UE registers as specified in clause 7.2.2 of TS 34.108 on the unicast carrier Cell 1. For 3.84 Mcps TDD IMB, the UE registers on the FDD unicast carrier cell 1. On the unicast carrier Cell 1, a Location Update Accept message shall be sent on reception of a Location Updating Request message from the UE. For a UE that supports both CS and PS domains or PS domain only, the Location Updating procedure could be replaced by the appropriate GMM registration procedure.

d) The SS activates Cell 32. Cell 32 indicates ‘reserved’ for future extension in the Cell Access Restriction IE of SIB3. The SS transmits the SYSTEM INFORMATION BLOCK TYPE 5 message indicating the configuration of the S-CCPCH carrying MCCH within the IE " Secondary CCPCH system information MBMS". In addition to broadcasting System Information, MCCH messages are transmitted by the SS on these cells using MBMS configuration C2 (one PTM session ongoing) and Default1 MCCH scheduling according to clause 11.1 or 11.2 of TS 34.108. The service is carried on a 129.6kbps RB for MTCH with 80 ms TTI as specified in clause 6.10.3.4.4.6(FDD) or a 124 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.10.3.4.4.9 (3.84 Mcps TDD)or 124.4 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.11.7.2.2.1 (3.84 Mcps TDD IMB) or clause 6.11.5.4.4.9 (1.28 Mcps TDD) or clause 6.11.6.4.4.9 (7.68 Mcps TDD).

f) SS delays for a period of time greater than or equal to 10 times the T_barred setting used in the Cell Access Restriction IE on Cells 32 (say 120 seconds). Note: If the UE sends CLOSE UE TEST LOOP COMPLETE at this stage then a test failure is recorded.

g) The SS sends OPEN UE TEST LOOP. The UE responds with OPEN UE TEST LOOP COMPLETE.

h) MBMS National Service 1 is de-activated at the UE.

i) The SS sends CLOSE UE TEST LOOP to activate RLC SDU counting on the MTCH (Transmission identity corresponding to National Service 2).

j) The SS activates Cell 37 as well as Cell 32. Cell 37 indicates ‘reserved’ for operator use in the Cell Access Restriction IE of SIB3. The SS transmits the SYSTEM INFORMATION BLOCK TYPE 5 message indicating the configuration of the S-CCPCH carrying MCCH within the IE " Secondary CCPCH system information MBMS". In addition to broadcasting System Information, MCCH messages are transmitted by the SS on these cells using MBMS configuration C2 (one PTM session ongoing) and Default1 MCCH scheduling according to clause 11.1 or 11.2 of TS 34.108. The service is carried on a 129.6kbps RB for MTCH with 80 ms TTI as specified in clause 6.10.3.4.4.6(FDD) or a 124 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.10.3.4.4.9 (3.84 Mcps TDD) or 124.4 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.11.7.2.2.1 (3.84 Mcps TDD IMB) or clause 6.11.5.4.4.9 (1.28 Mcps TDD) or clause 6.11.6.4.4.9 (7.68 Mcps TDD).

The SS then sends CLOSE UE TEST LOOP to activate RLC SDU counting on MTCH (Transmission identity indicating the MBMS National Service 1 (see TS 34.108 clause 11.2.4). The UE responds with CLOSE UE TEST LOOP COMPLETE.

b) The SS powers on Cell 31 at T1.

c) National Service 1 ongoing on MBSFN Cell 31 (see TS 34.108 clause 11.2.4) is selected at the UE. The UE determines from the MBMS UNMODIFIED SERVICES INFORMATION and MBMS GENERAL INFORMATION messages on the MCCH of Cell 33 that the selected National Service is available on inter frequency neighbour cell 31.

d) The UE reselects to MBSFN carrier on URFCN Ch. 3 and camps on Cell 31. The SS transmits the SYSTEM INFORMATION BLOCK TYPE 5 message indicating the configuration of the S-CCPCH carrying MCCH within the IE " Secondary CCPCH system information MBMS". In addition to broadcasting System Information, MCCH messages are transmitted by the SS on Cell 31 using MBMS configuration C2 (one PTM session ongoing) and Default1 MCCH scheduling according to clause 11.2 of TS 34.108. The service is carried on a 124 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.10.3.4.4.9 (3.84 Mcps TDD) or 124.4 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.11.7.2.2.1 (3.84 Mcps TDD IMB) or clause 6.11.5.4.4.9 (1.28 Mcps TDD).or clause 6.11.6.4.4.9 (7.68 Mcps TDD).

e) The UE shall perform the MCCH acquisition procedure. The UE shall start receiving the p-t-m radio bearer for the ongoing activated MBMS service indicated in the MBMS UNMODIFIED SERVICES INFORMATION message according to the configuration defined in the MBMS CURRENT CELL P-T-M INFORMATION (one ongoing session corresponding to the service activated at the UE). The UE closes the test loop and starts counting successfully received RLC PDUs on the MTCH. The UE will send CLOSE UE TEST LOOP COMPLETE.

f) The SS broadcasts 10 RLC SDUs on the MTCH configured on the MBMS p-t-m radio bearer for National Service 1 on Cell 31.

g) The SS sends UE TEST LOOP MODE 3 RLC SDU COUNTER REQUEST and waits for the UE to respond with UE TEST LOOP MODE 3 RLC SDU COUNTER RESPONSE. The SS shall check that the counter returned by the UE for the MTCH of the activated service in the UE TEST LOOP MODE 3 RLC SDU COUNTER RESPONSE is > 0.

Table 8.5.1.1 illustrates the downlink power to be applied for the 3 cells at various time instants of the test execution.

a) The UE is camping on Cell 1 and Cell 33. The SS sends ACTIVATE RB TEST MODE on the unicast carrier and the UE responds with ACTIVATE RB TEST MODE COMPLETE.

b) The SS sends CLOSE UE TEST LOOP to activate RLC SDU counting on the MTCH of Cell 33 (Transmission identity of the activated local service)

c) The SS notifies on MCCH about the start of an MBMS session, corresponding to the national service activated by the UE. For one modification period. MCCH messages are transmitted by the SS on Cell 33 using MBMS configuration C4 (one PTM session starting) and Default1 MCCH scheduling according to clause 11.2 of TS 34.108.

d) MCCH messages are then transmitted by the SS on Cell 33 using MBMS configuration C2 (one PTM session ongoing) and Default1 MCCH scheduling according to clause 11.2 of TS 34.108. The service is carried on a 124 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.10.3.4.4.9 (3.84 Mcps TDD) or 124.4 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.11.7.2.2.1 (3.84 Mcps TDD IMB) or clause 6.11.5.4.4.9 (1.28 Mcps TDD) or clause 6.11.6.4.4.9 (7.68 Mcps TDD).

e) The UE shall start receiving the p-t-m radio bearer for the ongoing activated MBMS service indicated in the MBMS UNMODIFIED SERVICES INFORMATION message according to the configuration defined in the MBMS CURRENT CELL P-T-M INFORMATION (one ongoing session corresponding to the service activated at the UE). The UE closes the test loop and starts counting successfully received RLC PDUs on the MTCH. The UE will send CLOSE UE TEST LOOP COMPLETE.

f) The SS broadcasts 10 RLC SDUs on the MTCH configured on the MBMS p-t-m radio bearer for the selected local service on Cell 33.

h) The SS sends OPEN UE TEST LOOP. The UE responds with OPEN UE TEST LOOP COMPLETE.

i) The SS sends CLOSE UE TEST LOOP to activate RLC SDU counting on the MTCH (Transmission identity corresponding to National Service 1).
