8.5.6 MBMS Controlling Cell Change
34.123-13GPPPart 1: Protocol conformance specificationRelease 15TSUser Equipment (UE) conformance specification
8.5.6.1 MBMS Controlling Cell Change – Idle mode – Frequency Layer Convergence – HCS Not Used / MBMS Selected Service
8.5.6.1.1 Definition
Test to verify that the UE performs the cell reselection correctly if system information parameters Qoffset, Qhyst, Qoffmbms and Treselection are applied for non-hierarchical cell structures. This test case is applicable for all UEs that support MBMS broadcast services.
8.5.6.1.2 Conformance requirement
When camped normally, the UE shall perform the following tasks:
– select and monitor the indicated PICH and PCH of the cell as specified in clause 8 according to information sent in system information;
– monitor relevant System Information. This is specified in [8];
– perform necessary measurements for the cell reselection evaluation procedure;
– execute the cell reselection evaluation process on the following occasions/triggers:
1) UE internal triggers, so as to meet performance as specified in [22] and [23];
2) When information on the BCCH used for the cell reselection evaluation procedure has been modified
If the UE supports MBMS and MBMS is active in the cell and the UE is permitted to receive MBMS services in the cell, the UE shall perform MBMS tasks as specified in subclause 6.3 of TS 25.304.
…
The cell-ranking criterion R is defined by:
where:
the signalled value Qoffmbms is only applied to those cells (serving or neighbouring) belonging to the MBMS PL
…
The cells shall be ranked according to the R criteria specified above, deriving Qmeas,n and Qmeas,s and calculating the R values using CPICH RSCP, P-CCPCH RSCP and the averaged received signal level as specified in [22] and [23] for FDD, TDD and GSM cells, respectively.
The offset Qoffset1s,n is used for Qoffsets,n to calculate Rn, the hysteresis Qhyst1s is used for Qhysts to calculate Rs. For UE in RRC connected mode states CELL_PCH or URA_PCH the hysteresis Qhysts takes the value Qhyst1s,PCH to calculate Rs, if provided in SIB4 [see 8]. For UE in RRC connected mode state CELL_FACH the hysteresis Qhysts takes the value Qhyst1s,FACH to calculate Rs, if provided in SIB4 [see 8].
…
If an FDD cell is ranked as the best cell and the quality measure for cell selection and re-selection is set to CPICH RSCP, the UE shall perform cell re-selection to that FDD cell. If this cell is found to be not suitable, the UE shall behave according to subclause 5.2.6.1.3 of TS 25.304.
…
In all cases, the UE shall reselect the new cell, only if the following conditions are met:
– the new cell is better ranked than the serving cell during a time interval Treselection. For UE in RRC connected mode states CELL_PCH or URA_PCH the interval Treselections,PCH applies, if provided in SIB4 [see 8], while for UE in RRC connected mode state CELL_FACH the interval Treselections,FACH applies, if provided in SIB4 [see 8]. For hierarchical cell structures when high mobility state has not been detected, if according to the HCS rules the serving cell is not ranked then all the ranked cells are considered to be better ranked than the serving cell.

3GPP TS 25.304 clauses 5.2.5.1, 5.2.6.1.4.
8.5.6.1.3 Test purpose
1. To verify that a UE in idle mode calculates R from Qhyst, and Qoffset and Qoffmbms, which triggers the cell reselection evaluation process.
2. To verify that a UE in idle mode performs a Serving Cell Reselection to the Preferred Layer at Session Start.
3. To verify that a UE in idle mode performs an intra-frequency Cell Reselection on the Preferred Layer during an ongoing Session

The UE is in CELL_FACH state in Cell 21. The SS notifies on MICH and MCCH about the start of an MBMS session and waits for the UE to activate MTCH reception.
The SS orders the UE to move to CELL_PCH state by transmitting a PHYSICAL CHANNEL RECONFIGURATION message with the RRC state indicator set to “CELL_PCH”.
The SS applies the power settings of “T1” in table 8.5.6.3-1. At this point the UE shall reselect to Cell 24 and send a CELL UPDATE message on the CCCH. SS then replies with CELL UPDATE CONFIRM message on the downlink DCCH and orders the UE to stay in CELL_FACH state. The UE replies with a UTRAN MOBILITY INFORMATION CONFIRM message, and waits for the UE to activate MTCH reception. The MBMS radio bearer on MTCH is put into loopback mode 3.
The SS orders the UE to move to CELL_PCH state by transmitting a PHYSICAL CHANNEL RECONFIGURATION message with the RRC state indicator set to “CELL_PCH”. The UE responds with PHYSICAL CHANNEL RECONIGURATION COMPLETE.
The SS provides information about the ongoing MBMS service in cell 24 by sending MBMS UNMODIFIED SERVICES INFORMATION. The SS informs the UE about Cell 26 as neighbouring cell by sending MBMS NEIGHBOURING CELL P-T-M RB INFORMATION in Cell 24. The SS sends 10 RLC SDUs of MBMS data in neighbouring cell 26.
The SS transmits a PAGING TYPE 1 message to the UE on the PCH and the UE moves to CELL_FACH state, sending a CELL UPDATE message. The SS replies with a CELL UPDATE CONFIRM message and UE confirms the received C-RNTI to be used in CELL FACH state by transmitting a UTRAN MOBILITY INFORMATION CONFIRM message on the uplink DCCH.
Then the SS 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 SS checks that the reported number is greater than the number reported previously at step 14 of expected sequence.
The SS orders the UE to move to CELL_PCH state by transmitting a PHYSICAL CHANNEL RECONFIGURATION message with the RRC state indicator set to “CELL_PCH”. When the PHYSICAL CHANNEL RECONFIGURATION COMPLETE message has been received, the SS sends 10 RLC SDUs of MBMS data in serving Cell 24.
The SS applies the power settings of “T2” in table 8.5.6.3-1. At this point the UE shall reselect to Cell 26 and send a CELL UPDATE message on the CCCH. SS then replies with CELL UPDATE CONFIRM message on the downlink DCCH and orders the UE to stay in CELL_FACH state. The UE replies with a UTRAN MOBILITY INFORMATION CONFIRM message.
The SS provides information about the ongoing MBMS service in cell 26 by sending MBMS UNMODIFIED SERVICES INFORMATION. The SS informs the UE about Cell 24 as neighbouring cell by sending MBMS NEIGHBOURING CELL P-T-M RB INFORMATION in Cell 26.
The SS 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 SS checks that the UE has received greater number of RLC SDU than reported in previous step 25 of expected sequence.
The SS orders the UE to move to CELL_PCH state by transmitting a PHYSICAL CHANNEL RECONFIGURATION message with the RRC state indicator set to “CELL_PCH” and the UE responds with PHYSICAL CHANNEL RECONIGURATION COMPLETE.
The SS sends 10 RLC SDUs of MBMS data in neighbouring Cell 24.The SS transmits a PAGING TYPE 1 message to the UE on the PCH and the UE moves to CELL_FACH state, sending a CELL UPDATE message. The SS replies with a CELL UPDATE CONFIRM message and UE confirms the received C-RNTI to be used in CELL FACH state by transmitting a UTRAN MOBILITY INFORMATION CONFIRM message on the uplink DCCH.
The SS 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 SS checks that the reported number is greater than the number previously reported by the UE at step 34 of expected sequence.
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.
NOTE: If the UE fails the test because of selecting the wrong cell, the operator may re-run the test.

8.5.6.4 MBMS Controlling Cell Change – Idle mode – Frequency Layer Convergence – With HCS / MBMS Selected Service
8.5.6.4.1 Definition
Test to verify that the UE performs the cell reselection correctly for hierarchical cell structures. This shall be done according to the HCS priority, the received signal quality value Q and the quality level threshold criterion H. This test case is applicable for all UEs that support MBMS broadcast services.
8.5.6.4.2 Conformance requirement
When camped normally, the UE shall perform the following tasks:
– select and monitor the indicated PICH and PCH of the cell as specified in clause 8 according to information sent in system information;
– monitor relevant System Information. This is specified in [8];
– perform necessary measurements for the cell reselection evaluation procedure;
– execute the cell reselection evaluation process on the following occasions/triggers:
1) UE internal triggers, so as to meet performance as specified in [22] and [23];
2) When information on the BCCH used for the cell reselection evaluation procedure has been modified
If the UE supports MBMS and MBMS is active in the cell and the UE is permitted to receive MBMS services in the cell, the UE shall perform MBMS tasks as specified in subclause 6.3 of TS 25.304.
…
In the cell reselection process, an MBMS PL shall only be applicable while the UE is receiving an MBMS session from one or more of the ongoing activated MBMS services for which this PL is indicated.
…
The measurement rules below apply in Idle, URA_PCH, CELL_PCH states. In CELL_FACH state the UE is required to perform measurements on all intra-frequency, inter-frequency and inter-RAT cells listed in system information according to requirements specified in [10]. In Idle, URA_PCH, CELL_PCH and CELL_FACH states the UE shall only consider those cells the UE is mandated to measure according to the measurement rules below as measured cells in the cell reselection criteria (subclause 5.2.6.1.4).
If the system information broadcast in the serving cell indicates that HCS is used, then for intra-frequency and inter-frequency measurements, the UE shall:
use HCS priority1 as the HCS priority broadcast in the system information and apply the following rule:
IF an MBMS PL is used THEN
– If the UE is in HCS low mobility state, for serving cell and neighbour cells belonging to the MBMS PL set the HCS priority = HCS priority1 + HCS_OFFmbms.
– If the UE is in HCS high mobility state, for serving cell and neighbour cells belonging to the MBMS PL set the HCS priority = HCS priority1.
– for serving cell and neighbour cells not belonging to the MBMS PL, set the HCS priority = HCS priority1.
IF an MBMS PL is not used THEN
For serving cell and all neighbour cells set HCS priority = HCS priority1
…
The quality level threshold criterion H for hierarchical cell structures is used to determine whether prioritised ranking according to hierarchical cell re-selection rules shall apply, and is defined by:
…
The cell-ranking criterion R is defined by:
where:
the signalled value Qoffmbms is only applied to those cells (serving or neighbouring) belonging to the MBMS PL
where:
TEMP_OFFSETn applies an offset to the H and R criteria for the duration of PENALTY_TIMEn after a timer Tn has started for that neighbouring cell.
TEMP_OFFSETn and PENALTY_TIMEn are only applicable if the usage of HCS is indicated in system information.
…
If HCS is used in the serving cell the UE shall perform ranking of all cells that fulfil the criterion S among
1. when in low-mobility (see subclause 5.2.6.1.2),
– all measured cells, that have the highest HCS_PRIO among those cells that fulfil the criterion H >= 0.
– all measured cells, not considering HCS priority levels, if no cell fulfil the criterion H >= 0.
…
If the usage of HCS is indicated in system information, TEMP_OFFSET1n is used for TEMP_OFFSETn to calculate TOn. If it is indicated in system information that HCS is not used, TEMP_OFFSETn is not applied when calculating Rn. The best ranked cell is the cell with the highest R value.
…
If a TDD or GSM cell is ranked as the best cell, then the UE shall perform cell re-selection to that TDD or GSM cell
…
If an FDD cell is ranked as the best cell and the quality measure for cell selection and re-selection is set to CPICH RSCP, the UE shall perform cell re-selection to that FDD cell. If this cell is found to be not suitable, the UE shall behave according to subclause 5.2.6.1.3.
…
The cells shall be ranked according to the R criteria specified above, deriving Qmeas,n and Qmeas,s and calculating the R values using CPICH RSCP, P-CCPCH RSCP and the averaged received signal level as specified in [22] and [23] for FDD, TDD and GSM cells, respectively.
The offset Qoffset1s,n is used for Qoffsets,n to calculate Rn, the hysteresis Qhyst1s is used for Qhysts to calculate Rs. For UE in RRC connected mode states CELL_PCH or URA_PCH the hysteresis Qhysts takes the value Qhyst1s,PCH to calculate Rs, if provided in SIB4 [see 8]. For UE in RRC connected mode state CELL_FACH the hysteresis Qhysts takes the value Qhyst1s,FACH to calculate Rs, if provided in SIB4 [see 8].
…
If an FDD cell is ranked as the best cell and the quality measure for cell selection and re-selection is set to CPICH RSCP, the UE shall perform cell re-selection to that FDD cell. If this cell is found to be not suitable, the UE shall behave according to subclause 5.2.6.1.3 of TS 25.304.
…
In all cases, the UE shall reselect the new cell, only if the following conditions are met:
– the new cell is better ranked than the serving cell during a time interval Treselection. For UE in RRC connected mode states CELL_PCH or URA_PCH the interval Treselections,PCH applies, if provided in SIB4 [see 8], while for UE in RRC connected mode state CELL_FACH the interval Treselections,FACH applies, if provided in SIB4 [see 8]. For hierarchical cell structures when high mobility state has not been detected, if according to the HCS rules the serving cell is not ranked then all the ranked cells are considered to be better ranked than the serving cell.
…
The UE shall perform the MBMS frequency layer selection procedure upon receiving the IE "MBMS Preferred frequency information", when specified explicitly e.g. as in subclause 8.6.9.2, or when the priority for an MBMS service as indicated by upper layers changes.
The UE shall:
1> if there exist two or more preferred frequencies for services included in variable MBMS_ACTIVATED_SERVICES:
2> request from upper layers the priorities of the different MBMS services included in variable MBMS_ACTIVATED_SERVICES for which a preferred frequency has been received.
1> if the UE is in idle mode:
2> if a preferred frequency layer applies for a service included in variable MBMS_ACTIVATED_SERVICES:
3> select the preferred frequency indicated for the MBMS service(s) prioritised most by upper layers for which a preferred frequency exists as the preferred frequency.

Method C is applied (as described and used in clause 6 of TS 34.123-1).
The SS activates Cell 21, Cell 24 and Cell 26 and monitors them for access request from the UE. The UE is in idle mode state on Cell 21.The UE receives at notification via MCCH, an MBMS MODIFIED SERVICES INFORMATION message including a preferred frequency in the IE “MBMS preferred frequency”. The HCS_OFFmbms is added to the normal HCS priority level of cells on this MBMS preferred frequency. Cell 24 and Cell 26 have the highest priority.
The UE shall consider this frequency as the preferred frequency layer for cell re-selection. The SS waits for random access requests from the UE. The UE moves to Cell 24 at session start for the concerned MBMS service. The UE shall store the frequency information of the frequency on which the UE was operating prior to cell-reselection to the preferred frequency in the variable MBMS_PREV_FREQUENCY_INFORMATION.
The HCS_OFFmbms is added to the normal HCS priority level of cells on this MBMS preferred frequency. Cell 24 and Cell 26 have the highest priority.
The SS transmits an MBMS MODIFIED SERVICE INFORMATION message which includes in the “Modified service list” for the MBMS activated service “MBMS required UE action” set to “Acquire counting info” and MBMS ACCESS INFORMATION message, which includes the MBMS Short Transmission ID associated to the MBMS activated service and “Access probability factor – Idle” set to 0 (corresponds to an actual Probability Factor = 1).
The UE shall transmit an RRC CONNECTION REQUEST message, with “Establishment cause” set to “MBMS reception”. The SS transmits a RRC CONNECTION SETUP. The UE establishes an RRC connection and transmits an RRC CONNECTION SETUP COMPLETE message.
The UE receives an MBMS MODIFIED SERVICES INFORMATION message “MBMS required UE action” IE set to “Acquire PTM RB info”. The UE receives an MBMS NEIGHBOURING CELL P-T-M RB INFORMATION including MBMS neighbouring cell information for Cell 26. The UE shall apply the MBMS p-t-m radio bearer configuration procedure to acquire the radio bearer configuration for the MBMS service provided by the SS.
The UE starts receiving the indicated p-t-m radio bearer.
The SS applies the power settings of “T1” in table 8.5.6.4-1. The SS waits for random access requests from the UE. The UE shall reselect to Cell 26.
The UE receives an MBMS UNMODIFIED SERVICES INFORMATION message “MBMS required UE action” IE set to “Acquire PTM RB info”. The UE receives an MBMS NEIGHBOURING CELL P-T-M RB INFORMATION including MBMS neighbouring cell information for Cell 24. The UE shall apply the MBMS p-t-m radio bearer configuration and continues receiving the indicated p-t-m radio bearer.

The UE is in the CELL_DCH state in Cell 21. The SS notifies on MICH and MCCH about the start of an MBMS session and waits for the UE to activate MTCH reception. The MBMS radio bearer on MTCH is put into loopback mode 3.
The SS sends 10 RLC SDUs of MBMS data on MTCH in Cell 21 on the concerned MBMS radio bearer. The 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 SS checks that the UE has received at least one RLC SDU.
The SS applies the power settings of “T1” in table 8.5.6.5-1 and orders an inter-frequency hard handover to Cell 24 by transmitting a PHYSICAL CHANNEL RECONFIGURATION message. The UE establishes the dedicated physical channel in Cell 24 and replies with a PHYSICAL CHANNEL RECONFIGURATION COMPLETE message, and waits for the UE to activate MTCH reception.
The SS provides information about the ongoing MBMS services in cell 24 by sending MBMS UNMODIFIED SERVICES INFORMATION. The SS informs the UE about Cell 26 as neighbouring cell by sending MBMS NEIGHBOURING CELL P-T-M RB INFORMATION in Cell 24.
The SS sends 10 RLC SDUs of MBMS data in cell 24. The SS 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 SS checks that the reported number is greater than zero.
The SS then sends 10 RLC SDUs of MBMS data in neighbouring cell 26 and SS 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. UE should be able to receive the MBMS data from neighbouring Cell 26 when camped in Cell 24. The SS checks that the reported number is greater than the number reported by the UE at step 16 of expected sequence. The SS applies the power settings of “T2” in table 8.5.6.5-1 and then orders handover to Cell 26 by transmitting a PHYSICAL CHANNEL RECONFIGURATION message. The UE establishes the dedicated physical channel in Cell 26 and replies with a PHYSICAL CHANNEL RECONFIGURATION COMPLETE message.
The SS provides information about the ongoing MBMS service in cell 26 by sending MBMS UNMODIFIED SERVICES INFORMATION. The SS informs the UE about Cell 24 as neighbouring cell by sending MBMS NEIGHBOURING CELL P-T-M RB INFORMATION in Cell 24.
The SS sends 10 RLC SDUs of MBMS data in cell 26. The SS 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 SS checks that the reported number is greater than the number reported by the UE at step 19.
The SS then sends 10 RLC SDUs of MBMS data in neighbouring cell 24 and SS 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 SS checks that the reported number is greater than the previous number reported by the UE at step 27.
The loopback mode 3 in the UE is deactivated.
SS calls for generic procedure C.3 to check that UE is in CELL_DCH state.
NOTE: If the UE fails the test because of selecting the wrong cell, the operator may re-run the test.
