Methods and corresponding apparatuses for LTE's WLAN mobility set prioritization are discussed. The method includes detecting an integrated WLAN and a legacy WLAN, measuring the connection quality of the integrated WLAN and/or the connection quality of the legacy WLAN, and determining whether to select the legacy WLAN over the integrated WLAN based on the measurement results. The method further includes detecting a WWAN using both licensed and unlicensed spectrum, and refraining from connecting to the legacy WLAN in response to the detecting.
