一、EUTRAN->WLAN重選

當(dāng)EUTRAN的服務(wù)器小區(qū)滿足以下條件

RSRPmeas < ThreshServingOffloadWLAN, LowP;or

RSRQmeas < ThreshServingOffloadWLAN,LowQ;? //RSRP或RSRQ小于門限值

切目標(biāo)WLAN小區(qū)滿足

ChannelUtilizationWLAN <ThreshChUtilWLAN, Low;and????????????//WLAN信道利用率

BackhaulRateDlWLAN > ThreshBackhRateDLWLAN, High;and?????//WLAN下行帶寬

BackhaulRateUlWLAN > ThreshBackhRateULWLAN, High; and???//WLAN上行帶寬

BeaconRSSI > ThreshBeaconRSSIWLAN,High;????????????????????????????//WLAN的RSSI

二、WLAN->EUTRAN重選

WLAN小區(qū)滿足

ChannelUtilizationWLAN >Thresh_{ChUtilWLAN, High}; or//WLAN信道利用率

BackhaulRateDlWLAN <Thresh_{BackhRateDLWLAN, Low}; or//WLAN下行帶寬

BackhaulRateUlWLAN <Thresh_{BackhRateULWLAN, Low}; or//WLAN上行帶寬

BeaconRSSI <Thresh_{BeaconRSSIWLAN,Low}; //WLAN RSSI

目標(biāo)EUTRAN小區(qū)滿足

RSRPmeas >Thresh_{ServingOffloadWLAN, HighP;} and

RSRQmeas >Thresh_{ServingOffloadWLAN, HighQ;//RSRP和RSRQ要同時(shí)高于一定門限值}

三、參數(shù)說(shuō)明

參數(shù)	說(shuō)明
ThreshServingOffloadWLAN,LowP	從E-TURAN->WLAN的EUTRAN的RSRP門值
ThreshServingOffloadWLAN,HighP	從WLAN->EUTRAN的EUTRAN的RSRP門限
ThreshServingOffloadWLAN,LowQ ?	從E-TURAN->WLAN的EUTRAN的RSRQ門值
ThreshServingOffloadWLAN,HighQ	從WLAN->E-UTRAN的EUTRAN的RSRQ門值
ThreshChUtilWLAN, Low	從EUTRAN->WLAN的WLAN信道利用率門限值
ThreshChUtilWLAN, High	從WLAN->EUTRAN的WLAN信道利用率門限值
ThreshBackhRateDLWLAN, Low	從WLAN->E-UTRAN的WLANBACKHAUL下行帶寬門限值
ThreshBackhRateDLWLAN, High	從E-UTRAN->WLAN的WLANBACKHAUL下行帶寬門限
ThreshBackhRateULWLAN, Low	從WLAN->EUTRAN的WLANBACKHAU上行帶寬門限
ThreshBackhRateULWLAN, High	從EUTRAN->WLAN的WLANBACKHAU上行帶寬門限
ThreshBeaconRSSIWLAN,Low	從WLAN->EUTRAN的WLAN的beacon幀的RSSI值
ThreshBeaconRSSIWLAN,High	從E-UTRAN->WLAN的WLAN的beacon幀的RSSI值
TsteeringWLAN	業(yè)務(wù)分流時(shí)的時(shí)間
WLAN identifiers	WLAN的ID，可以使SSID、BSSID、HESSID

相關(guān)參數(shù)可以在LTE的SIB7 或者RRC沖配置消息中下發(fā)
