User equipment, core network node, and methods in a radio communications network

A method performed by a Core Network, CN, node, for assisting a first User Equipment, UE, in applying policy enforcement for data traffic in an Uplink, UL, session, which UL data session is from the first UE to a data network via a Radio Access Network, RAN, a Core Network, CN, and a first Network Slice, NS, in a radio communications network, the method comprising:

• collecting policy enforcement data for the first NS,
• collecting information relating to data traffic from second UEs via the RAN, the CN and second NSs, which data traffic information relates to a radio coverage area associated with the location of the first UE,
• assisting the first UE, by sending a first information to the first UE, which first information relates to the collected:
• policy enforcement data for the specific NS, and
• data traffic from the second UEs via the RAN, the CN and second NSs,
• which sent information assists the first UE to predict available resources for transmitting data traffic in the UL data session based on the sent information, and apply the policy enforcement for the data traffic in the UL data session based on the prediction.

A first User Equipment, UE, configured to apply policy enforcement for data traffic in an Uplink, UL, session, which UL data session is adapted to be from the first UE to a data network via a Radio Access Network, RAN, a Core Network, CN, and a first Network Slice, NS, in a radio communications network, the first UE being configured to:

• obtain first information from a CN node in the CN, which first information is adapted to relate to:
• policy enforcement data for the first NS, and
• data traffic from second UEs via the RAN, the CN and second NSs, which data traffic information relates to a radio coverage area associated with the location of the first UE,
• upon establishing the UL data session, measure data traffic performance and radio conditions in the RAN,
• predict available resources for transmitting data from the first UE towards the data network via the RAN, the CN, and the first NS, based on the obtained first information, the measured data traffic performance and radio conditions in the RAN, and
• apply policy enforcement for the data traffic in the UL data session based on the prediction.
