Title
(EN) SESSION CONTINUITY FOR SUPPORT OF SIMULTANEOUS TERMINAL ACCESSES
(FR) CONTINUITÉ DE SESSION POUR SUPPORT D'ACCÈS SIMULTANÉS DE TERMINAUX
Abstract
(EN)
Methods and nodes are provided for supporting session continuity for terminals capable of having simultaneous accesses while served by a plurality of gateways. Distinct binding cache entries (BCE) are stored for a terminal, each BCE being related to one of the gateways serving the terminal. The BCEs identify the terminal, provide an address allocated thereto for getting access at a gateway, and identify the gateway providing the access. When detection is made that two of more BCEs relate to the same terminal for distinct gateways, address information is sent to each other gateway.
(FR)
L'invention porte sur des procédés et des nœuds pour supporter une continuité de session pour des terminaux aptes à posséder des accès simultanés tout en étant desservis par une pluralité de passerelles. Des entrées de cache d'association (BCE) distinctes sont stockées pour un terminal, chaque BCE étant relative à l'une des passerelles desservant le terminal. Les BCE identifient le terminal, fournissent une adresse allouée à celui-ci pour obtenir un accès au niveau d'une passerelle, et identifie la passerelle fournissant l'accès. Lorsqu'il est détecté que deux BCE ou plus sont relatives au même terminal pour des passerelles distinctes, des informations d'adresse sont envoyées à chaque autre passerelle.
