8.2.10.1.2 Conformance requirement
The rules in this sub-clause are only applicable for WLANs for which identifiers have been signalled to the UE by UTRAN and the UE is capable of access network selection and traffic steering rules. Coexistence with ANDSF based WLAN selection and traffic steering methods on the UE is based on mechanism described in TS 23.402 [23]. The rules refer to the following WLAN quantities:
…
The upper layers in the UE shall be notified (see TS 24.302 [28]) when and for which WLAN(s), that matches all the provided identifiers (in sub-clause 5.10.3) for a specific entry in the list, the following conditions 1 and 2 for steering traffic from UTRAN to WLAN are satisfied for a time interval TsteeringWLAN:
1. In the UTRAN serving cell:
Qrxlevmeas < ThreshServingOffloadWLAN, Low; or
Qqualmeas < ThreshServingOffloadWLAN, Low2.
2. In the target WLAN:
ChannelUtilizationWLAN < ThreshChUtilWLAN, Low; and
BackhaulRateDlWLAN > ThreshBackhRateDLWLAN, High; and
BackhaulRateUlWLAN > ThreshBackhRateULWLAN, High; and
BeaconRSSI > ThreshBeaconRSSIWLAN, High.
The UE shall not consider the metrics for which a threshold has not been provided. The UE shall evaluate the UTRAN conditions on the serving cell in Idle mode, URA_PCH, CELL_PCH, CELL_FACH and CELL_DCH. If not all metrics related to the provided thresholds can be acquired for a WLAN BSS, the UE shall exclude that WLAN BSS from the evaluation of the above rule.
…
The upper layers in the UE shall be notified (see TS 24.302 [28]) when the following conditions 3 or 4 for steering traffic from WLAN to UTRAN are satisfied for a time interval TsteeringWLAN:
1. In the source WLAN:
ChannelUtilizationWLAN > ThreshChUtilWLAN, High; or
BackhaulRateDlWLAN < ThreshBackhRateDLWLAN, Low; or
BackhaulRateUlWLAN < ThreshBackhRateULWLAN, Low; or
BeaconRSSI < ThreshBeaconRSSIWLAN, Low.
2. In the target UTRANcell:
Qrxlevmeas > ThreshServingOffloadWLAN, High; and
Qqualmeas > ThreshServingOffloadWLAN, High2.
The UE shall not consider the metrics for which a threshold has not been provided. The UE shall evaluate the UTRAN conditions on the serving cell in Idle mode, URA_PCH, CELL_PCH, CELL_FACH and CELL_DCH.

Test Procedure
Initially, UE is in State 6-16 on Cell 1 as specified in clause 7.4 of TS 34.108
The SS activates the WLAN Cell 39. In Cell 1, SS transmits a UTRAN MOBILITY INFORMATION message to the UE which includes Threshold Serving RSCP and Threshold Backhaul Bandwidth. UE sends the UTRAN MOBILITY INFORMATION CONFIRM message to SS
SS configures the cell 1 and cell 39 parameters according to column “T1” in 8.2.10.1.4-1. After TsteeringWLAN expiry, SS calls for generic test procedure C.6.1 of TS 34.123-1 to check that the PDN connection is offloaded from UTRAN to WLAN (Cell 39).
SS configures the cell 1 and cell 39 parameters according to column “T2” in 8.2.10.1.4-2. After TsteeringWLAN expiry, SS calls for generic test procedure C.6.2 to check that the PDN connection is offloaded from WLAN to UTRAN.

Test Procedure
Initially, UE is in PS+PS-DCCH+DTCH_DCH (State 6-16) on Cell 1 as specified in clause 7.4 of TS 34.108
The SS activates the WLAN Cell 39. In Cell 1, SS transmits a UTRAN MOBILITY INFORMATION message to the UE which includes Threshold Serving RSRQ and Threshold Backhaul. UE sends the UTRAN MOBILITY INFORMATION CONFIRM message to SS
SS configures the cell 1 and cell 39 parameters according to column “T1” in 8.2.10.4.4-1/2. After TsteeringWLAN expiry, SS calls for generic test procedure C.6.1 of TS 34.123-1 to check that the PDN connection is offloaded from UTRAN to WLAN (Cell 39).
SS configures the cell 1 and cell 39 parameters according to column “T2” in 8.2.10.4.4-1/2. After TsteeringWLAN expiry, SS calls for generic test procedure C.6.2 to check that the PDN connection is offloaded from WLAN to UTRAN.

Test Procedure
Initially, UE is in Connected State.
The SS activates the WLAN Cell 39. In Cell 1, SS transmits a UTRAN MOBILITY INFORMATION message to the UE which includes ThreshServingOffloadWLAN, Low and ThreshChUtilWLAN, Low. UE sends the UTRAN MOBILITY INFORMATION CONFIRM message to SS.
UE is moved to Idle State and T330 starts.
The timer T330 expires.
SS configures the cell 1 and cell 39 parameters according to column “T1” in 8.2.10.2.4-1/2. After TsteeringWLAN expiry, SS calls for generic test procedure C.6.1 of TS 34.123-1 to check that the PDN connection is offloaded from UTRAN to WLAN (Cell 39) as per values of ThreshServingOffloadWLAN, Low and ThreshChUtilWLAN, Low in SIB23.

8.2.10.7.2 Conformance requirement
The rules in this sub-clause are only applicable for WLANs for which identifiers have been signalled to the UE by UTRAN and the UE is capable of access network selection and traffic steering rules. Coexistence with ANDSF based WLAN selection and traffic steering methods on the UE is based on mechanism described in TS 23.402 [23]. The rules refer to the following WLAN quantities:
|

WLAN channel utilization as defined in sub-clause 8.4.2.30 in [24] |
|
BackhaulRateDlWLAN |
WLAN DLBandwidth as defined in sub-clause 9.1.2 in [25] |
|
BackhaulRateUlWLAN |
WLAN ULBandwidth as defined sub-clause 9.1.2 in [25] |
|
BeaconRSSI |
WLAN Beacon RSSI as defined in [26] and [27] |
The upper layers in the UE shall be notified (see TS 24.302 [28]) when and for which WLAN(s), that matches all the provided identifiers (in sub-clause 5.10.3) for a specific entry in the list, the following conditions 1 and 2 for steering traffic from UTRAN to WLAN are satisfied for a time interval TsteeringWLAN:
1. In the UTRAN serving cell:
Qrxlevmeas < ThreshServingOffloadWLAN, Low; or
Qqualmeas < ThreshServingOffloadWLAN, Low2.
2. In the target WLAN:
ChannelUtilizationWLAN < ThreshChUtilWLAN, Low; and
BackhaulRateDlWLAN > ThreshBackhRateDLWLAN, High; and
BackhaulRateUlWLAN > ThreshBackhRateULWLAN, High; and
BeaconRSSI > ThreshBeaconRSSIWLAN, High.
The UE shall not consider the metrics for which a threshold has not been provided. The UE shall evaluate the UTRAN conditions on the serving cell in Idle mode, URA_PCH, CELL_PCH, CELL_FACH and CELL_DCH. If not all metrics related to the provided thresholds can be acquired for a WLAN BSS, the UE shall exclude that WLAN BSS from the evaluation of the above rule.
The upper layers in the UE shall be notified (see TS 24.302 [28]) when the following conditions 3 or 4 for steering traffic from WLAN to UTRAN are satisfied for a time interval TsteeringWLAN:
1. In the source WLAN:
ChannelUtilizationWLAN > ThreshChUtilWLAN, High; or
BackhaulRateDlWLAN < ThreshBackhRateDLWLAN, Low; or
BackhaulRateUlWLAN < ThreshBackhRateULWLAN, Low; or
BeaconRSSI < ThreshBeaconRSSIWLAN, Low.
2. In the target UTRANcell:
Qrxlevmeas > ThreshServingOffloadWLAN, High; and
Qqualmeas > ThreshServingOffloadWLAN, High2.
The UE shall not consider the metrics for which a threshold has not been provided. The UE shall evaluate the UTRAN conditions on the serving cell in Idle mode, URA_PCH, CELL_PCH, CELL_FACH and CELL_DCH.
If the FDD UE is configured with DCH only, the reference cell to use, for the rules defined in this sub-clause, is the best cell in active set.
…
The WLAN access selection and traffic routing can be controlled either by ANDSF rules or by RAN rules.
The ANDSF rules control the WLAN access selection and traffic routing if:
a) the UE has ANDSF rules but no RAN rules; or
b) the UE has both ANDSF rules and RAN rules; and:
1) the UE is not capable to simultaneously route IP traffic to both 3GPP access and WLAN; and:
A) the UE is not roaming and the UE has at least one ISMP rule from HPLMN;
B) the UE is roaming in a VPLMN contained in the visited PLMNs with preferred rules and the UE has at least one ISMP rule from VPLMN; or
C) the UE is roaming in a VPLMN not contained in the visited PLMNs with preferred rules and the UE has at least one ISMP rule from HPLMN; or
2) the UE is capable to simultaneously route IP traffic to both 3GPP access and WLAN; and:
A) the UE is not roaming and the UE has a valid ISRP rule from HPLMN;
B) the UE is roaming in a VPLMN contained in the visited PLMNs with preferred rules and the UE has a valid ISRP rule from VPLMN; or
C) the UE is roaming in a VPLMN not contained in the visited PLMNs with preferred rules and the UE has a valid ISRP rule from HPLMN.
The RAN rules control the WLAN access selection and traffic routing if:
a) the UE has RAN rules but no ANDSF rules; or
b) the UE has both ANDSF rules and RAN rules; and:
1) the UE is not capable to simultaneously route IP traffic to both 3GPP access and WLAN; and:
