Method to facilitate the use of multiple communication protocols in a communication network

摘要

A mobile node using non-Mobile Internet Protocol version 6 is able to successfully communicate via Mobile Internet Protocol version 4 infrastructure via an encapsulating tunnel as is established between a first network element (such as a Packet Data Serving Node) and a second network element (such as a Home Agent). Extensions and/or codes can be conveyed via Mobile Internet Protocol version 4 Registration Requests/Responses that facilitate the automated establishment of, for example, a 6to4 tunnel for these purposes.
