CA 2509393

In a wireless communication system, a method for early determination of network support for Mobile IP is disclosed. A mobile node is in communication with a wireless network. Then a test is performed for a disconnect condition wherein the disconnect condition is an early indication of network non-support for Mobile IP as identified by at least a requirement for authentication. Early indication relates to identification of the non-support for Mobile IP prior to or during network packet connection. If the disconnect condition is found, the mobile node disconnects from the wireless network. If the disconnect condition is not found, the mobile node stays connected to the wireless network.

L'invention concerne un procédé de détermination précoce de prise en charge réseau pour IP mobile dans un système de communication sans fil. Un noeud mobile est en communication avec un réseau sans fil. On réalise alors un test en vue de détecter un état de déconnexion, cet état de déconnexion constituant une indication précoce de non-prise en charge réseau pour IP mobile, paramètre identifié au moyen d'au moins une exigence d'authentification. L'indication précoce se rapporte à l'identification de la non-prise en charge réseau pour IP mobile avant ou pendant une connexion par paquets réseau. Si l'état de déconnexion est détecté, le noeud mobile se déconnecte du réseau sans fil. Si l'état de déconnexion n'est pas détecté, le noeud mobile reste connecté au réseau sans fil.
