Definitions

  • the architecture 100 includes a home public land mobile network (HPLMN) 102 that communicates with the Internet 104.
  • the architecture 100 also includes several distributed gateways (D-GW) 106a-e.
  • D-GW is a logical entity placed at an edge of the network, close to a wireless transmit/receive unit (WTRU) 140a, 140b. Multiple D-GWs exist in a DMM domain, anchoring mobility sessions of the WTRUs attached to the domain.
  • Each D-GW 106a-e provides network services 108a-e to a network section llOa-e.
  • the HPLMN 102 includes a multi-hop cellular network (MCN) 120 and one of the D-GWs (shown in Figure 1 as D-GW 106e).
  • the MCN 120 includes several nodes 122 to communicate within the MCN, a packet data network gateway (PGW) 124, a home subscriber server (HSS) 126, an authentication, authorization, and accounting server (AAA) 128, a serving gateway (SGW) 130, and a mobility management entity (MME) 132.

  • the WTRU 906, equipped with the logical interface capability, may attach to two different D-GWs (D-GWl 904a and D-GW2 904b), configuring two IPv6 addresses (PrefA::UEl/64 and PrefB::UEl/64), each locally anchored at the respective D-GW.
  • D-GWl 904a may detect congestion on its access link, it may want to offload some traffic to another access interface available on the WTRU 906. To do so, D-GWl 904a may first need to know that the WTRU 906 is simultaneously attached to D-GW2 904b, and then may need to negotiate with D-GW2 904b about the offloading.
  • the flow split signaling request message includes a modified proxy binding update message.

Abstract

La présente invention se rapporte à un procédé permettant d'obtenir de la robustesse dans une gestion de mobilité distribuée. Une unité d'émission/réception sans fil (WTRU pour Wireless Transmit/Receive Unit) est fixée à une première passerelle distribuée (D-GW pour Distributed GateWay) par l'intermédiaire d'une interface. Un tunnel entre la première passerelle D-GW et une seconde passerelle D-GW est préfourni. L'unité WTRU est fixée à la seconde passerelle D-GW et détachée de la première passerelle D-GW. Le tunnel entre la première passerelle D-GW et la seconde passerelle D-GW qui a été préfournie, est créé. Un trafic de données entre l'unité WTRU et la première passerelle D-GW est envoyé par l'intermédiaire de l'interface sur la seconde passerelle D-GW et en utilisant le tunnel entre la première passerelle D-GW et la seconde passerelle D-GW, ce qui permet d'obtenir de la robustesse.
