Patent

CA 2626083

In preferred embodiments, a wireless network system features buffering of data packets transmitted to mobile nodes. The system is transparent to the mobile node, so that the mobile node is not required to request service from the network, or negotiate service parameters with the network. An EAPOL-Start and binding update messages initiate and terminate the buffering, and also commence pre-authentication and smooth handoff reporting, respectively.

Dans des modes de réalisation préférés, un sous-système de réseau sans fil met en place la mise au tampon de données de paquets de données transmises vers les noeuds mobiles. Le système est transparent vis-à-vis du noeud mobile, et de cette manière le noeud mobile n'est pas nécessaire pour demander un service au réseau et ne négocie pas les paramètres de service avec le réseau. Un démarrage EAPON et des messages de mise à jour obligatoire lancent et terminent la mise au tampon et commencent aussi la pré-authentification de manière à lisser le rapport de transfert, respectivement.
