Method and label switching router for providing mobility to a mobile host in a mobile network employing multi-protocol label switching

Procédé et routeur de commutation d'étiquettes facilitant la mobilité pour un terminal mobile dans un réseau mobile au moyen d'un protocole MPLS

Verfahren und Etikettvermittlungsrouter zur Unterstützung der Mobilität eines mobilen Endgeräts in einem MPLS (Multi-protocol Label Switching) Mobilfunknetz

Abstract

A method is disclosed which provides mobility to a mobile host (MH) in a mobile network employing multi-protocol label switching (MPLS) transport at least in a part of the network. During a handover, the mobile host receives a broadcast message from a new egress node of the MPLS network. It attaches to the new egress node, whereby the egress node leams the MH identifier. The new egress node sends a request message containing the identifier of the MH and its own identifier to one or a plurality of ingress nodes of the MPLS network. Each ingress node checks a mapping table for label switched paths (LSPs) serving the identified MH. If such paths exist, the ingress node initiates the set up of a new LSP to the new egress node for each existing LSP.
