Abstract: A method of updating a background data transfer, BDT, policy negotiated between an application function, AF, and a Core Network, CN, is disclose. The method is performed by a Policy Control Function, PCF, of the CN and comprises determining updated BDT policy information including updated conditions for the negotiated BDT policy and at least one candidate BDT policy for the AP to select when the PCF determines that the negotiated BDT policy is affected by degraded network performance. The determined updated BDT policy information is then sent to the AF by the PCF using notification type interaction, thereby effectively updating the negotiated BDT policy.

The method comprises receiving, from one of the congestion monitoring units, an indication that one of the mobile entities is affected by a congestion, storing said one congestion monitoring unit from which the indication is received as the current congestion monitoring unit for said one mobile entity, receiving, from another congestion monitoring unit, the indication that said one mobile entity is affected by a congestion, and indicating, in response to the indication received from the other monitoring unit, to the current congestion monitoring unit a release of congestion information relating to said one mobile entity.

Abstract: In scenarios where the quality of service is negotiated through a signalling layer whereas the services are actually carried through a bearer layer, application functions at the signalling layer are not always aware of how quality of service is individually accomplished at the bearer layer on a service basis. The invention provides a method and devices whereby events are detected on a service data flow basis at a detection device in the bearer layer and notified towards an application device in the signalling layer via a control device between the signalling and the bearer layer. The list of events to be notified is obtainable at the control device from the application device and is included in Quality of Service related rules, along with service data flow filters. This Quality of Service related rules are provided to the detection device for inspecting individual service data flows in order to detect and notify the indicated events.

Abstract: The embodiments herein relates to a method for enabling multiple bearer support upon congestion situations in a communication network. The PCC architecture is enabled to determine whether separate bearers need to be established for service(s) that demand MBR>GBR when no ECN support is provided. This is provided in nodes and methods receiving, using a receiving unit (301), an indication of session establishment for a bearer from a bearer binding function unit (113, 115), obtaining profile information with Quality of Service, QoS, information about maximum bit rate, MBR, and guaranteed bit rate, GBR, related to the bearer; determining that the MBR is larger than the GBR, making a policy decision, and transmitting, using the transmitting unit (305), an acknowledgement of session establishment to the bearer binding function unit with an indicator that a separate bearer is to be established.
