Summary: | One object of the present invention is a Proxy-Gn entity for mobility between UMA access and GPRS/UMTS access, said Proxy-Gn entity anchoring a PDP context for a Mobile Station MS whatever the access type UMA or GPRS/UMTS for this MS, said anchored PDP context having three terminations, two access terminations and one network termination: - GPRS/UMTS access termination, which receives GTP control messages from a SGSN, - UMA access termination, which receives Session Management requests from the MS, - Network termination, which is the termination towards a GGSN, and which owns the IP address allocated to the MS.
L'invention concerne, entre autres, une entité a Proxy-Gn permettant la mobilité entre un accès UMA et un accès GPRS/UMTS, ladite entité Proxy-Gn ancrant un contexte PDP pour une station mobile MS, quel que soit le type d'accès, UMA ou GPRS/UMTS, pour cette MS, ledit contexte PDP ancré comprenant trois terminaisons, deux terminaisons d'accès et une terminaison de réseau : - une terminaison d'accès GPRS/UMTS qui reçoit des messages de contrôle GTP d'un SGSN, - une terminaison d'accès UMA qui reçoit des requêtes de gestion de session de la MS, - une terminaison de réseau qui est la terminaison vers un GGSN et qui possède l'adresse IP attribuée à la MS. |
