A system and method for performing mobile node registration. The system comprises a terminal device (102) for transmitting packetized data, and a wireless communication device (104) coupled to said terminal device for monitoring said packetized data for an Internet Protocol (IP) address contained in an IP address request. The wireless communication device (104) initiates mobile node registration (512) using said IP address if said IP address request is for a static IP address. The wireless communication device prevents (417) the terminal device from sending or receiving packetized data when initiating mobile node registration, and allows said terminal device to send and received packetized data upon completion of mobile node registration. As a result, the mobile node registration occurs transparently to the terminal device, obviating the need for the terminal device to have its own Mobile IP support.

L'invention concerne un système et un procédé d'enregistrement d'un noeud de mobile. Ce système comporte un terminal (102) de transmission de données mises en paquets, et un dispositif de radiocommunication (104) couplé au terminal pour surveiller lesdites données mises en paquets pour une adresse IP contenue dans une demande d'adresse IP. Pour lancer un enregistrement d'un noeud de mobile (512), le dispositif de radiocommunication (104) utilise ladite adresse IP dans la mesure où ladite demande d'adresse IP a pour objectif une adresse IP statique. Le dispositif de radiocommunication empêche (417) le terminal d'envoyer ou de recevoir des données mises en paquets lorsqu'il lance l'enregistrement d'un noeud de mobile et il autorise le terminal à envoyer ou à recevoir des données mises en paquets dès l'achèvement de l'enregistrement du noeud de mobile. En conséquence, l'enregistrement d'un noeud de mobile se passe de manière transparente pour le terminal. Ainsi, il devient inutile pour le terminal d'avoir sa propre compatibilité de mobilité IP.
