Abstract
The invention concerns a method for optimizing a UE PDN (Packet Data Network) connection when said UE enters a VPLMN (Visited PLMN) characterized by automatically allocating a default bearer to said UE in said VPLMN during Tracking Area Update procedure. The method according to the invention is preferably but not exclusively used for allowing a local breakout of user plane or control plane traffic when the UE is roaming between several PLMNs.
