Core network node, user equipment and methods in a packet communications network

A method performed by a User Equipment, UE, for assisting a core network node in handling a data service session in a packet communication network, which packet communication network is configured to support fixed access between the UE and an access network node, the method comprising:

• monitoring a bandwidth over the fixed access for a data service session between the UE and the Data Network via the fixed access,
• deciding whether the monitored bandwidth over the fixed access is below the bandwidth requirement authorized to the UE, and
• assisting the core network node in handling the data service session in the packet communication network by sending to the core network node, the decision whether the monitored bandwidth over the fixed access is below the bandwidth requirement authorized to the UE,
• wherein the assisting is performed to assist a Policy Control Function of the core network node in handling the data service session in the packet communication network by sending to the Policy Control Function, the decision whether the monitored bandwidth over the fixed access is below the bandwidth requirement authorized to the UE, and
• wherein the bandwidth over the fixed access for the data service session is monitored by a Customer Premises Equipment related the UE, and wherein whether the monitored bandwidth over the fixed access is below the bandwidth requirement authorized to the UE is decided, by the Customer Premises Equipment related the UE.
