  10. 10. #DASCongress Integrating WiFi into Het net 1. Common hardware for WiFi and 3GPP: Available 2. Network selection and traffic steering: On-going Standard/Feature Benefits Limitations ANDSF Access network discovery and selection Requires device support Hotspot 2.0/ Passpoint, Next Gen Hotspot (NGH) Secure seamless roaming onto Wi-Fi, best AP selection Requires device support Device-driven RAN 2 Optimized network selection Early stage Requires device support IP Session Mobility Application/session continuity Not available yet Requires device support Access Selection Network selection based on historical performance Not real-time Not per device Real-Time Traffic Steering Network selection based on real-time 3GPP and Wi-Fi network status Not in standards today
