Title: (EN) FRAMEWORK OF MEDIA-INDEPENDENT PRE-AUTHENTICATION IMPROVEMENT
(JA) 媒体非依存事前認証改善策のフレームワーク
Abstract:
(EN) PROBLEM TO BE SOLVED: To provide a framework of pre-authentication improvement which is independent from a medium.

SOLUTION: A method for reducing the effect of undesired switch back of a mobile node between a first network and a second network includes: (a) maintaining a context related to the first network for a period of time, so that the context can be immediately restored when the mobile returns to the first network; and (b) allowing the mobile node to use the context when returning to the first network.

【課題】媒体に依存しない事前認証改善策のフレームワーク。
【解決手段】第1のネットワークと第2のネットワークの間でモバイルノードの不所望切換復帰の影響を軽減する方法であって、a)前記モバイルが第1のネットワークに戻るときにコンテキストが迅速に回復できるように前記第1のネットワークに関連するコンテキストを一時期維持することと、b)前記第1のネットワークに戻るときに前記モバイルノードに前記コンテキストを使用させることとを備える。
