Abstract
A method in a first network node for handling traffic tracing of a user equipment. The first network node is comprised in a first Radio Access Technology, RAT, system. The first network node starts a handover procedure to handover the user equipment from the first RAT system to a second RAT system. The user equipment has an active traffic tracing ongoing in the first RAT system. The traffic tracing relates to tracing associated with communication between the user equipment and the first RAT system. The first network node sends a message to a second network node in the second RAT system. The message is sent directly to the second network node or via one or more intermediate network nodes. The message comprises one or more parameters relating to the ongoing traffic tracing of the user equipment. The parameters define when the traffic tracing is to continue in the second RAT system.
