Abstract: A method of offload selection for a UE to select between 3GPP RAT and WLAN cell is provided. The UE receives configuration information that applies to selecting WLAN or 3GPP radio access technology (RAT). The UE determines if the UE may perform WLAN offload by evaluating 3GPP radio access network (RAN) conditions where at least one RAN condition is related to a radio signal strength or a radio signal quality in 3GPP RAT. The UE then determines if there is at least one suitable WLAN cell by evaluating WLAN conditions. The UE also determines if there is candidate traffic for WLAN offload. Finally, the UE steers the determined traffic to WLAN if the UE may perform WLAN offload and if there is at least one suitable WLAN cell. Otherwise, the UE steers the determined traffic to 3GPP RAT.

Abstract translation: 提供了一种用于UE在3GPP RAT和WLAN小区之间进行选择的卸载选择的方法。 UE接收适用于选择WLAN或3GPP无线电接入技术（RAT）的配置信息。 UE通过评估其中至少一个RAN条件与3GPP RAT中的无线电信号强度或无线电信号质量相关的3GPP无线电接入网络（RAN）条件来确定UE是否可以执行WLAN卸载。 然后，UE通过评估WLAN条件来确定是否存在至少一个合适的WLAN小区。 UE还确定是否存在用于WLAN卸载的候选业务。 最后，如果UE可以执行WLAN卸载并且如果存在至少一个合适的WLAN小区，则UE将所确定的流量引导到WLAN。 否则，UE将确定的业务引导到3GPP RAT。
