Abstract
(EN)
A gateway support node (GGSN+HA) for a packet radio network, arranged to provide Internet Protocol, or IP, mobility for a mobile station (MS). The gateway support node (GGSN+HA) is interoperable with at least one home agent (HA) and at least one serving support node (SGSN), for routing data packets to/from the mobile station (MS). It comprises a protocol stack (18, 20) for supporting at least a layer 1 (L1) protocol, a layer 2 (L2) protocol, and a network layer (L3) protocol, the network layer (L3) protocol supporting at least IP protocol. It also comprises the functions of the home agent (HA) and it is arranged to support Mobile IP protocol on the network layer (L3). Preferably, the protocol stack (20) is streamlined by routing data packets to/from the integrated home agent/gateway node (GGSN+HA) using only the network layer (L3) protocol and the layer 2 and layer 1 protocols.

L'invention concerne un noeud de prise en charge de passerelle (GGSN+HA) pour un réseau de radiocommunications par paquets, agencé pour fournir une mobilité dans un protocole Internet ou PI à une station mobile (SM). Le noeud de prise en charge de passerelle (GGSN+HA) est compatible avec au moins un agent local (HA) et au moins un noeud de prise en charge de desserte (SGSN), afin d'acheminer les paquets de données vers/à partir de la station mobile (SM). Il comprend une pile de protocoles (18, 20) destinée à prendre en charge au moins un protocole de couche 1 (L1), un protocole de couche 2 (L2), et un protocole de couche réseau (L3), le protocole de couche réseau (L3) prenant en charge au moins un protocole (PI). Il comprend également les fonctions de l'agent local (HA) et il est agencé pour prendre en charge le protocole PI mobile sur la couche réseau (L3). De préférence, la pile de protocoles (20) est rationalisée par un cheminement des paquets de données vers/à partir de l'agent local/noeud passerelle intégré (GGSN+HA) n'utilisant que le protocole de la couche réseau (L3) et les protocoles de la couche 2 et de la couche 1.
