Abstract
In a network that supports mobility of a mobile node, a tunnel between a first mobility node and a second mobility node is established in the network. The established tunnel is according to a tunneling protocol (e.g., Generic Routing Encapsulation tunneling protocol) that uses at least one key (208) for encapsulating data communicated through the tunnel. The symmetric or asymmetric key may be used for identifying a particular traffic flow in either the forward or the reverse direction between mobility nodes, e.g., when supporting mobility nodes that are using overlapping private IPv4 addressing. Signaling is communicated to provide mobility support of the mobile node according to a mobility protocol, where the mobility protocol is selected from among a Proxy Mobile Internet Protocol and Mobile IP version 6.
