Abstract
A method and apparatus for bi-directional transfer of information between a corresponding host and a mobile host in a communications network where each user is assigned a unique network address. In accordance with the teaching of the invention, mobility M- and N-proxies are provided for intercepting data incoming from the mobile host and redirecting it to the corresponding host via transitional transmission sessions established by the proxies, such that the migration of the mobile host from one coverage area to another is transparent to the network application running on the mobile host.
