DOI 10.1007/s11277-011-0423-3 IP Flow Mobility in PMIPv6 Based Networks: Solution Design and Experimental Evaluation

Abstract The ability of offloading selected IP data traffic from 3G to WLAN access net-works is considered a key feature in the upcoming 3GPP specifications, being the main goal to alleviate data congestion in cellular networks while delivering a positive user experience. Lately, the 3GPP has adopted solutions that enable mobility of IP-based wireless devices relocating mobility functions from the terminal to the network. To this end, the IETF has standardized Proxy Mobile IPv6 (PMIPv6), a protocol capable to hide often complex mobility procedures from the mobile devices. This paper, in line with the mentioned offload require-ment, further extends PMIPv6 to support dynamic IP flow mobility management across access wireless networks according to operator policies.
