Abstract

Cette invention concerne un dispositif de communication mobile qui est agencé en tant que BS (104) pour une MS (103) afin d'exécuter une communication où un transfert est permis, par une communication WiMAX. Le dispositif de communication mobile inclut un moyen de génération pour générer des informations de paramétrage qui corrèlent un identificateur unique de la MS (103) avec un identificateur unique d'un ASN-GW (102) comme ancre de la MS (103) lorsque la MS (103) effectue une entrée dans un CSN (101). De plus, le dispositif de communication mobile inclut un moyen de transmission pour transmettre les informations de paramétrage générées par le moyen de génération en plaçant les informations sur un élément d'informations primitif lors d'un transfert selon le déplacement de la MS (103).
