6.4.1 WLAN Offload / Cell Selection / UTRA RRC_Idle to/from WLAN (Qrxlevmeas, BeaconRSSI)
6.4.1.1 Definition
6.4.1.2 Conformance requirement
1. The UE is in UTRA RRC_IDLE state, and UE receives SystemInformationBlockType23 including RAN-assisted WLAN interworking data and configured with ThreshServingOffloadWLAN, Low and ThreshBeaconRSSIWLAN, High. When the UE measures that Serving cell has condition: Qrxlevmeas < ThreshServingOffloadWLAN, Low and the target WLAN AP has condition: BeaconRSSI > ThreshBeaconRSSIWLAN, High, the UE initiates handover attach to WLAN after TsteeringWLAN.
2. The UE is associated with WLAN AP and attached to WLAN ePDG and configured with ThreshBeaconRSSIWLAN, Low and ThreshServingOffloadWLAN, High. When the UE measures that WLAN AP has condition: BeaconRSSI < ThreshBeaconRSSIWLAN, Low and UTRA Serving cell has condition: Qrxlevmeas < ThreshServingOffloadWLAN, High, the UE initiates handover attach to WLAN cell after TsteeringWLAN.
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:
|
ChannelUtilizationWLAN |
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]. |
|

6.4.2.2 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.

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.
