METHOD AND DEVICE FOR RE-USING IPSEC TUNNEL IN CUSTOMER PREMISES EQUIPMENT

A method for re-using an existing IPSec tunnel for multiple services. The IPSec tunnel is established from customer premises equipment to the core network to support licensed frequency communications, such as a femtocell. UMA communication using unlicensed frequencies may be carried out by re-using the IPSec tunnel to securely route UMA communications from a UMA device to a UNC within the core network via the customer premises equipment. The network determines whether to redirect UMA communications through an existing IPSec tunnel by determining whether a newly established second IPSec tunnel for UMA communications originates from an access point collocated with a femtocell that has an existing IPSec tunnel. Un procédé pour réutiliser un tunnel IPSec pour de multiples services. Le tunnel IPSec est établi à partir des installations dabonnés au réseau central pour permettre les communications par fréquences sous licence, comme une femtocellule. Les communications daccès mobile sans licence (UMA) utilisant des fréquences exploitées sans licence peuvent être effectuées en réutilisant le tunnel IPSec pour acheminer les communications UMA de manière sécurisée dun dispositif UMA à un UNC au sein du réseau de base par le biais des installations dabonnés. Le réseau détermine sil est nécessaire de rediriger les communications UMA à travers un tunnel IPSec existant en déterminant si un deuxième tunnel IPSec nouvellement établi pour les communications UMA provient dun point daccès colocalisé avec une femtocellule comportant un tunnel IPSec existant.
