Mobility optimisation based on IP prefix information in WLAN SSID

摘要

The patent application concerns networks, mobile nodes and a method for handover of a first connection (Fig. 1, "first connection C1") between a mobile node (Fig. 1, "MN") and a first access point (Fig 1, "AP 1") of a first access network (Fig. 1, "access network AN1") to a second connection (Fig. 1, "second connection C2") between the mobile node (Fig. 1, "MN") and a second access point (Fig 1, "AP 4") of a second access network (Fig. 1, "access network AN 2"),
wherein a broadcast message (Fig. 1, "Broadcast", "origSSID<escl><prefix>" / "origSSID<esc2><DNS-name>") is sent by the second access point (Fig 1, "AP 4") wherein the broadcast message (Fig. 1, "Broadcast", "origSSID<esc1><prefix>" / "origSSID<esc2><DNS-name>") comprises layer-3-information (Fig. 1, "Broadcast", "origSSID<esc1><prefix>" / "origSSID<esc2><DNS-name>") concerning the second connection (Fig. 1, "second connection C2").
