ABSTRACT:
Methods and apparatus for improving tunneling techniques and reducing packet loss in mobile communications systems are described. The methods and apparatus are well suited for use with Mobile IP and can facilitate handoff operations. A mobile node establishes multiple tunnels, representing downlinks, from the mobile node perspective. The different downlink tunnels are through different access nodes but terminate at the same home agent. The mobile node maintains, at most, a single uplink tunnel at any given time with the home agent. Tunnels representing uplinks and downlinks are managed independently. Thus, each of the uplink and downlink tunnels can have different lifetimes and can be created/removed independently allowing for flexibility in handoff operations.
