Method and system for handling a traffic flow between local service clouds

A network node for handling a traffic flow of a User Equipment, UE, the network node configured to be related to a first local service cloud, and the traffic flow is to be related to an application session served by the first local service cloud, the network node being configured to:

• create a unique Network Address Translated, NAT:ed, Internet Protocol, IP, address mapping to an UE IP address of the UE, the unique NAT:ed IP address having a local IP address prefix assigned to the first local service cloud, the unique NAT:ed IP address being usable for the traffic flow both before and after a handover of the UE from the first local service cloud to a neighbouring second local service cloud, and the unique NAT:ed IP address is unique at least in all local service clouds neighboring to the first local service cloud, including the second local service cloud;
• and
• assign the unique NAT:ed IP address to the UE for local break out of the traffic flow of the application session to the first local service cloud.
