Abstract
The embodiments herein relate to a method performed by a SMF, for handling local breakout of traffic. The SMF receives, from a PCF, policy information indicating traffic that should be routed via a second UPF to a second DN. The SMF provides, to a first UPF, a first traffic detection filter for detecting the traffic indicated in the received policy information. The SMF detects that there is traffic matching the first traffic detection filter. The SMF sets up, according to the policy information, a local breakout to the second UPF when the matching traffic has been detected. The setting-up comprises setting-up the second UPF.
