(EN) PROVIDING OFFLOADS IN A COMMUNICATION NETWORK
(FR) ASSURER DES DÉLESTAGES DANS UN RÉSEAU DE COMMUNICATION
Abstract
(EN)
This disclosure relates to a system and method for offloading selected data to an alternate communication network. The offloading provides another route for selected packet traffic that can relieve the burden on a mobile operator's network, such as the backhaul and core networks. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has exponentially increased. Upgrading the existing network that was designed for voice calls is not desirable or practical for many mobile operators. A offload gateway is provided that inspects packets and determines those packets to offload to an alternate network as well as providing mobility management to allow for seamless handoffs and gateway relocations.

Cette invention concerne un système et un procédé pour délester des données sélectionnées vers un autre réseau de communication. Le délestage fournit une autre route pour un trafic de paquets sélectionné qui peut fluidifier la charge sur un réseau d'opérateur mobile, tel que la liaison terrestre et des réseaux d'infrastructure. Tandis que la prolifération de contenus de données enrichis et de dispositifs mobiles de plus en plus capables s'est poursuivie, la quantité de données communiquées sur des réseaux d'opérateurs mobiles a augmenté de manière exponentielle. L'amélioration du réseau existant qui a été conçu pour des appels vocaux n'est pas souhaitable ou réalisable pour de nombreux opérateurs mobiles. L'invention concerne également une passerelle de délestage qui inspecte des paquets et détermine les paquets à délester vers un autre réseau, et assure également une gestion de la mobilité pour permettre des transferts sans coupure et des relocalisations de passerelles.
