Abstract
A new message format and protocol in an IP mobility system. Deallocation of a mobile node's IP address during a multipart communication session on a foreign network can cause serious communication and accounting errors. The new message format and protocol should eliminate the premature deallocation of a mobile node's IP address, which should reduce associated communication and accounting errors.
