  1. Network awareness in a multiple-network environment Hidetoshi Yokota KDDI

  2. Network-aware Webapps <body> <h1> … </h1> • Choose the right I/F (e.g., 3G, LTE and WiFi) • By content type • By URL • Choose the right content based on the network interface • High quality content is selected when WiFiis used • Adjust traffic volume according to the interface usage • Skip downloading when the NW I/F is heavily used • Adjust traffic volume according to the network condition • Skip downloading when packet loss rate is high <video> </video> <audio> </audio> </body> <body> <a href=abc.htm> <a href=xyz.htm> </body> NW I/F 3G Best effort bearer (QCI=8, non-GBR) WiFi QoS bearer (QCI=1, GBR)

  3. Possible approaches • Web API to retrieve more detailed information on the network interface(s) for more efficient network usage • Network information obtained solely by the terminal (e.g., Cellular and WiFi base stations, signal strength, error rate, throughput) • Network information obtained by cooperating with the network (e.g. access network load, backhaul load, congested APs) via 3GPP ANDSF or WFA Hotspot 2.0  Extension to Network information API? • Web API to control network interfaces for fine-grained network selection • Network interface control should support not only open/close, but also attachment to a specific base station in WiFi network, establishment of a dedicated bearer in cellular network, etc. • Support of concurrent usage of multiple networks and access network selection based on the content type (video/voice/text) Extension to/new features for Network interface API?
