Suitable authentication method for each user connection type with mobile IP adaptation

摘要

As IP Technology gains on cellular network between-node communication and mobility management will be processed through open networks such as the Internet, which causes increased process load by extra authentication needed between nodes beside the user authentication requisite for the existing mobile communications network. In this paper, we propose a method minimizing this authentication process load in Mobile IP technology. First, impact on mobility management capability by the current authentication process is shown with one experimental result. Then, as its solution, proposed a method reducing authentication frequency with networks' user connection type distinguishability and limited authentication process among associated nodes.
