摘要： A Policy Control Function, PCF, for use in a 5G core network, is configured to allow a consumer to retrieve from the PCF subscriber session information and Application Detection and Control rules relating to a subscriber session. Specifically, the PCF is configured to: receive (303) a request from a Session Management Function, SMF, for session management policies applying to the subscriber session; retrieve (305) policy data from a Unified Data Repository, UDR; and, based on the retrieved policy data, generate said Application Detection and Control rules relating to the subscriber session, and send (307) said Application Detection and Control rules to the TDF, thereby allowing the TDF to act as the consumer.

摘要： Techniques are provided to enable the SMF or other network node performing UPF selection to determine a computational resource demand, also referred to herein as the computational footprint, associated with a PDU session. The computational footprint can then be used by the SMF or other network node to inform the selection of the UPF.

摘要： There is provided a method performed by a session management function (SMF) node of a network for establishing a PFCP session. A plurality of service functions (SFs) are selected (102) to connect in a service function chain for handling the PFCP session. Each of the plurality of SFs is capable of activating a feature of the PFCP session and is supported by a user plane function (UPF) node. The selection is based on a load of each of the plurality of SFs. For each UPF node that supports one or more of the selected plurality of SFs, transmission of a request is initiated (104) to the UPF node to establish the PFCP session with the UPF node. The request comprises an indication of the one or more of the selected plurality of SFs that the UPF node supports.
