Abstract

La présente invention porte sur un procédé de gestion de réseau mobile et un routeur mobile se rapportant au domaine technique des communications et capable d'améliorer des performances de réseau et de réduire le gaspillage de ressources réseau. Le procédé comprend : la réception d'un premier message de demande d'enregistrement envoyé par un nœud mobile ou un nœud de rattachement dans un réseau mobile, le premier message de demande d'enregistrement comprenant des premières informations d'identification concernant le nœud mobile ou le nœud de rattachement, les premières informations d'identification comprenant des informations d'identité d'hôte et des informations d'adresse concernant le nœud mobile ou le nœud de rattachement, le remplacement des informations d'adresse dans les premières informations d'identification par les informations d'identité d'hôte concernant le routeur mobile de façon à obtenir des deuxièmes informations d'identification, l'envoi d'un deuxième message d'enregistrement à un serveur auquel le réseau mobile appartient, le deuxième message de demande d'enregistrement comprenant les deuxièmes informations d'identification. La présente invention est applicable à la gestion d'un réseau mobile.
