Abstract

See full text

A wireless communications device has network interfaces for accessing cellular data networks and Wi-Fi wireless local area networks. Wi-Fi offload allows data traffic to be moved away from the cellular network to the Wi-Fi network. To avoid any existing data sessions being broken during offload, Proxy Mobile IP (PMIP) must be supported by a Wi-Fi access point and associated Mobile Access Gateway. After Wi-Fi association and authentication, the wireless communication device probes the access point and MAG to determine whether PMIP is supported.
