The rules in this sub-clause are only applicable for WLANs for which identifiers has been signalled to the UE by E-UTRAN and the UE is capable of RAN-assisted WLAN interworking based on 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 [25]. The rules refer to the following quantities:

ChannelUtilizationWLAN	WLAN channel utilization as defined in subclause 8.4.2.30 in [26].
BackhaulRateDlWLAN	WLAN DLBandwidth as defined in subclause 9.1.2 in [27].
BackhaulRateUlWLAN	WLAN ULBandwidth as defined in subclause 9.1.2 in [27].
BeaconRSSI	WLAN Beacon RSSI as defined in [7].
RSRPmeas	Qrxlevmeas in RRC_IDLE, and PCell RSRP in RRC_CONNECTED as defined in TS 36.331 [3].
RSRQmeas	Qqualmeas in RRC_IDLE, and PCell RSRQ in RRC_CONNECTED as defined in TS 36.331 [3].

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 subclause 5.6.3) for a specific entry in the list, the following conditions 1 and 2 for steering traffic from E-UTRAN to WLAN are satisfied for a time interval Tsteering_WLAN:

1. In the E-UTRAN serving cell:

RSRPmeas < Thresh_{ServingOffloadWLAN, LowP;} or

RSRQmeas < Thresh_{ServingOffloadWLAN, LowQ;}

2. In the target WLAN:

ChannelUtilizationWLAN < Thresh_{ChUtilWLAN, Low}; and

BackhaulRateDlWLAN > Thresh_{BackhRateDLWLAN, High}; and

BackhaulRateUlWLAN > Thresh_{BackhRateULWLAN, High}; and

BeaconRSSI > Thresh_{BeaconRSSIWLAN, High};

The UE shall not consider the metrics for which a threshold has not been provided. The UE shall evaluate the E-UTRAN conditions on PCell only. 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 E-UTRAN are satisfied for a time interval Tsteering_WLAN:

3.In the source WLAN:

BackhaulRateDlWLAN < Thresh_{BackhRateDLWLAN, Low}; or

BackhaulRateUlWLAN < Thresh_{BackhRateULWLAN, Low}; or
