Integrating WiFi into Het net1. Common hardware for WiFi and 3GPP: Available2. 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-timeNot per device
Real-Time Traffic Steering
Network selectionbased on real-time 3GPP and Wi-Fi network status
Not in standards today
#DASCongress
Real-time Traffic Steering between 3GPP and WiFi
Always best connected in real time
Macro
Small Cell 3GPP+Wi-FiWi-Fi
Visibility of user’s mobile requirements as well as source and destination radio access networks dynamically determines connections
Mobile connection is steered between 3GPP and Wi-Fi
Each mobile device benefits from connection to the best radio access technology to address their requirements
