Embodiments disclosed herein relate to providing dynamic assignment of home agent and home address in wireless communications, such that a mobile node away from home may receive local access services from a visited network. In an embodiment, a mobile node accesses a visited network. The visited network authenticates the mobile node with its home network. The visited network then assigns a visited home agent and a home address for the mobile node. The mobile node subsequently performs secure binding with the visitor home agent. The mobile node proceeds with communications using the visitor home agent and home address.
L'invention porte sur l'attribution dynamique d'agents locaux et d'adresses locales dans des communications sans fil, si bien qu'un noeud mobile éloigné du domicile peut recevoir des services d'accès local d'un réseau visité. Dans un mode de réalisation, un noeud mobile accède à un réseau visité. Ce réseau visité authentifie le noeud mobile au moyen de son réseau local. Le réseau visité attribue ensuite un agent local visité et une adresse locale au noeud mobile. Le noeud mobile s'associe alors de manière sécurisée avec l'agent local du visiteur. Le noeud mobile poursuit les communications au moyen de l'agent local du visiteur et de l'adresse locale.
