8.5.2.1m MBMS PTM Session Reconfiguration – Change of Activated Service / MBSFN mode (FDD)
8.5.2.1m.1 Definition
This test is applicable for UEs that support MBMS broadcast services in MBSFN mode and which support either both transmit and receive functions or MBSFN receive only function.
8.5.2.1m.2 Conformance requirement
The UE applies the MCCH acquisition procedure to determine the MBMS services available in the cell and to initiate reception of the services that the UE has activated. The procedure applies to all UEs supporting MBMS, irrespective of their state (idle, URA_PCH, CELL_PCH, CELL_FACH and CELL_DCH).
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.
…
The UE shall detect the available MBMS services by acquiring the MBMS MODIFIED SERVICES INFORMATION and the MBMS UNMODIFIED SERVICES INFORMATION messages without delaying reading of MCCH until the next modification period and without stopping at the end of the modification period, in accordance with subclause 8.7.1.3.
…
For cells operating in MBSFN mode as indicated in subclause 8.1.1.6.3 the UE shall immediately acquire the MBMS GENERAL INFORMATION messages i.e. It shall not delay reception of these messages until it has completed the acquisition of the MBMS MODIFIED SERVICES INFORMATION and the MBMS UNMODIFIED SERVICES INFORMATION messages. Likewise for cells operating in MBSFN mode as indicated in subclause 8.1.1.6.3, the UE should immediately acquire the MBMS CURRENT CELL P-T-M RB INFORMATION.
The UE shall continue acquiring the above messages until it has received a consistent set of MCCH information e.g. Both the MBMS MODIFIED SERVICES INFORMATION and the MBMS UNMODIFIED SERVICES INFORMATION message should be acquired in the same modification period.
…
When requested to acquire MBMS control information other than the MBMS Access Information message, the UE shall:
1> if requested to start reading MCCH at the next modification period:
2> start reading MCCH at the beginning of the next modification period.
1> otherwise
2> start reading MCCH at the beginning of the next repetition period.
1> if requested to stop reading MCCH at the end of the modification period:
2> continue reading MCCH until the required MBMS control information is received or until the UE detects a TTI in which no MCCH information is transmitted, whichever is first;
2> continue reading MCCH in this manner at every subsequent repetition period, until the information is received correctly or until the end of the modification period.
1> otherwise:
2> continue reading MCCH until the required MBMS control information is received or until the UE detects a TTI in which no MCCH information is transmitted, whichever is first;
2> continue reading MCCH in this manner at every subsequent repetition period, until the information is received correctly.
NOTE 1: The UE may combine information received at different repetition periods within a modification period.
…
If the IE "MBMS required UE action" is included and concerns an MBMS activated service the UE shall:
…
1> if the IE "MBMS required UE action" is set to ‘Acquire PTM RB info’; or
1> if the IE "MBMS required UE action" is set to ‘Acquire counting info– PTM RBs unmodified’ and the UE is not receiving a p-t-m RB for the concerned service:
2> continue acquiring the MBMS COMMON P-T-M RB INFORMATION, MBMS CURRENT CELL P-T-M RB INFORMATION and the MBMS NEIGHBOURING CELL P-T-M RB INFORMATION messages without delaying reading of MCCH until the next modification period and without stopping at the end of the modification period, in accordance with subclause 8.7.1.3
2> act upon the MBMS COMMON P-T-M RB INFORMATION, MBMS CURRENT CELL P-T-M RB INFORMATION and the MBMS NEIGHBOURING CELL P-T-M RB INFORMATION message, if received, in accordance with subclause 8.7.5;
…
Upon completing the reception of the MBMS COMMON P-T-M RB INFORMATION and the MBMS CURRENT CELL P-T-M RB INFORMATION messages for an activated MBMS service, the UE shall:
1> if the UE is already receiving an MTCH and does not have the capability to receive the new service in addition:
2> the UE behaviour is undefined.
NOTE: In this case, the UE may request upper layers to prioritise the services and only receive the service(s) prioritised by upper layers.
1> act upon all received information elements as specified in subclause 8.6, unless specified otherwise in the following;
1> if the UE previously received the service by means of a p-t-m radio bearer from a cell belonging to another MBMS cell group:
2> re-establish RLC;
2> re-initialise PDCP.
1> start immediately to use the indicated configuration unless specified otherwise;
1> start or continue receiving the indicated p-t-m radio bearers depending on its UE capabilities.
The UE shall continue acquiring the above messages until it has received a consistent set of MCCH information i.e. the MBMS Modified services Information message, MBMS Unmodified services Information message, MBMS COMMON P-T-M RB INFORMATION and the MBMS CURRENT CELL P-T-M RB INFORMATION message should be acquired in the same modification period.
…
The UE shall:
1> if the IE "Secondary CCPCH system information MBMS" is included:
2> apply the Secondary CCPCH and FACH indicated by the IE "FACH carrying MCCH" for receiving MCCH.
1> otherwise, if the IE "Secondary CCPCH system information" includes the IE "MCCH configuration information":
2> apply the Secondary CCPCH and FACH indicated by the IE “MCCH configuration information” for receiving MCCH.
1> for TDD, if the IE "TDD MBSFN Information" is included:
2> apply the scrambling codes (as referenced by the "Cell parameters ID") to each timeslot indicated by "TDD MBSFN Information".
…
The UE shall select the Secondary CCPCH for acquiring MCCH information according to the following rules:
1> if System Information Block type 5 or System Information Block type 5bis is defined and includes an S-CCPCH within the IE "Secondary CCPCH system information" including a FACH for which the IE "MCCH configuration information" is included:
2> select that S-CCPCH and FACH for receiving MCCH.
1> otherwise if System Information Block type 5 or System Information Block type 5bis is defined and includes an SCCPCH within the IE "Secondary CCPCH system information MBMS" for which the IE "FACH carrying MCCH" is included:
2> select that S-CCPCH and FACH for receiving MCCH.

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, 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.
…
A UE entering CELL_DCH shall initiate the MBMS modification request procedure in the following cases:
1> if the UE has any MBMS Selected Service; and
1> if the IE "MCCH configuration information" was received in System Information Block Type 5 or System Information Block Type 5bis prior to entering CELL_DCH.
A UE completing an RRC Connection Setup procedure shall initiate the MBMS modification request procedure in the following cases:
1> if the UE has any MBMS Selected Service; and
1> if the IE "MCCH configuration information" was received in System Information Block Type 5 or System Information Block Type 5bis prior to completing the RRC Connection Setup procedure.
A UE in CELL_DCH shall initiate the MBMS modification request procedure in the following cases:
1> the preferred frequency applicable for the MBMS service prioritised by upper layers is different from the currently used frequency;
1> upper layers request to discontinue reception of an MBMS service provided via a p-t-p radio bearer e.g. because this inhibits reception of a higher priority service;
1> upon a change in selection of the MBMS Selected Services.
NOTE: The above case may occur upon receiving a dedicated notification or in other cases e.g. a change of transfer mode from p-t-p to p-t-m for the UE’s highest priority MBMS service.
…
If the IE "MBMS RB list released to change transfer mode" is included the UE shall:
1> perform the service prioritisation procedure as specified in subclause 8.5.26, taking into account that the MBMS service(s) for which the radio bearers are released will be provided via p-t-m radio bearer(s).
…
A UE in CELL_DCH shall initiate the MBMS modification request procedure in the following cases:

Test Procedure
The UE is in the CELL_FACH state and has selected the broadcast service or joined the multicast service to be provided by the SS..
The SS notifies on MICH and MCCH about the start of an MBMS session. The SS waits for the UE to start reception of the MBMS data on MTCH.
The MBMS radio bearer on MTCH is put into loopback mode 3.
The SS sends 10 RLC SDUs of MBMS data on MTCH on the concerned MBMS radio bearer, then retrieves the number of RLC SDUs on MTCH counted by the UE by sending the UE TEST LOOP MODE 3 RLC SDU COUNTER REQUEST message. The number of received RLC SDUs reported by the UE shall be at least one.
The SS then notifies on the MCCH the change in the MBMS session . The UE reconfigures the radio bearer to new configuration. The SS sends 10 RLC SDUs of MBMS data on the MTCH on the concerned MBMS radio bearer, then retrieves the number of RLC SDUs on MTCH counted by the UE by sending the UE TEST LOOP MODE 3 RLC SDU COUNTER REQUEST message. The number reported by the UE shall be one more than the value reported at the previous check.
The loopback mode 3 in the UE is deactivated.
SS calls for generic procedure C.2 to check that UE is in CELL_FACH state.

Test procedure
a) The UE is camping on Cell 1 and Cell 31. In addition to broadcasting System Information, MCCH messages are transmitted by the SS on Cell 31 using MBMS configuration C1 (no session ongoing) and Default1 MCCH scheduling according to clause 11.2 of TS 34.108.
b) The SS sends ACTIVATE RB TEST MODE on the unicast carrier and the UE responds with ACTIVATE RB TEST MODE COMPLETE.
c) The SS sends CLOSE UE TEST LOOP to activate RLC SDU counting on Cell 31 MTCH (Transmission identity indicating the MBMS activated service).
d) The SS notifies on MCCH about the start of an MBMS session for one modification period. MCCH messages are transmitted by the SS on Cell 31 using MBMS configuration C4 (one PTM session starting) and Default1 MCCH scheduling according to clause 11.2 of TS 34.108.
e) MCCH messages are then 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.
f) The UE establishes the p-t-m radio bearer for the activated service according to the specified service activation time (i.e. the first SFN of the modification period following the notification (step d). 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.
g) The SS broadcasts 10 RLC SDUs on the MTCH configured on the MBMS p-t-m radio bearer for the activated service. 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 clause 6.11.5.4.4.9 (1.28 Mcps TDD) or clause 6.11.6.4.4.9 (7.68 Mcps TDD).
h) The SS shall then send UE TEST LOOP MODE 3 RLC SDU COUNTER REQUEST. The UE shall 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. The SS shall store the counter value.
i) The SS notifies on MCCH about the modification of the MBMS session for one modification period. MCCH messages are transmitted by the SS on Cell 31 using MBMS configuration C4 (service modification indicated) and Default1 MCCH scheduling according to clause 11.2 of TS 34.108.
j) MCCH messages are then 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.
k) The UE reconfigures the p-t-m radio bearer for the activated service according to the received MBMS COMMON P-T-M RB INFORMATION at the specified service activation time (i.e. the first SFN of the modification period following the notification (step i).
l) The SS broadcasts 10 RLC SDUs on the modified MTCH configured on the MBMS p-t-m radio bearer for the activated service. The service is carried on a 259.2 kbps RB for MTCH with 80 ms TTI as specified in clause 6.10.3.4.4.7(FDD) or a 497.6 kbps RB for MBSFN MTCH with 80ms TTI as specified in clause 6.10.3.4.4.11 (3.84 Mcps TDD) or clause 6.11.5.4.4.11 (1.28 Mcps TDD) or clause 6.11.6.4.4.11 (7.68 Mcps TDD).
m) The SS shall then send UE TEST LOOP MODE 3 RLC SDU COUNTER REQUEST. The UE shall 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 corresponds to > 0 received RLC SDUs
