1. A device for dynamically classifying and re-classifying a data packet flow on a user plane of a core network domain, wherein the device is configured to classify and re-classify the data packet flow using packet detection rules, PDRs, and wherein each PDR is associated with at least one action to be applied to data packets matching the PDR, the device being configured to
receive one or more first data packets of a data packet flow;
determine that the received one or more first data packets match a first PDR to classify the data packet flow according to the first PDR;
trigger application of at least one first action associated with the first PDR to the one or more first packets;
receive one or more second data packets of the data packet flow, wherein the one or more second data packets are received after the one or more first data packets;
determine that the received one or more second data packets match a second PDR to re-classify the data packet flow according to the second PDR, wherein the second PDR is different from the first PDR;
trigger application of at least one second action associated with the second PDR to the one or more second data packets; and
receive a third instruction selectively disabling reporting of at least one measurement performed for the one or more first data packets matching the first PDR at least until it is determined that the second PDR is matched by the one or more second data packets.
