  • Publication number: 20230362024
    Abstract: A method of and a Session Management Function, SMF, for provisioning processing rules for user traffic at a User Plane Function, UPF, in a core network of a telecommunication network are disclosed. The core network comprises an Access and Mobility Management Function, AMF and a Policy Control Function, PCF. The SMF first transmits to the PCF a request for obtaining processing rules for user traffic; the SMF then receives from the PCF processing rules enabling at least one of a Uniform Resource Identifier, URI, level processing policy and a Server Name Indication, SNI, level processing policy for the user traffic and provision the received processing rules with the UPF. The UPF can then process user traffic based on the provisioned processing rules, differentiating the user traffic at the more detailed URI and/or SNI level.

  • Publication number: 20230336369
    Abstract: A method of operating a core network CN node is disclosed. A plurality of PCC rules are received corresponding to a plurality of applications used by a communication device. Each of the applications has a respective appID, and each of the PCC rules is associated with a respective application/appID. A first information element is generated based on a first PCC rule associated with a respective first application/appID including a first URR having a first URR Identifier and including first URR parameters associated with the first URR. A second information element is generated based on a second PCC rule associated with a respective second application/appID including a second URR having a second URR identifier without including second URR parameters associated with the second URR. A session establishment request message is transmitted to a second CN node. The session establishment request message includes the first and second information elements.

  • Publication number: 20230086421
    Abstract: The present disclosure provides methods for signaling QoS Flow control parameters, and corresponding NF entities. The method comprises generating one or more data flow rules associated with a QoS Flow and a QoS Flow profile. The data flow rules include parameters specific to a data flow that belongs to the QoS Flow, while the QoS Flow profile includes parameters that are common to all data flows that belong to the same QoS Flow. The present disclosure further discloses a corresponding method of receiving the QoS Flow control parameters. The present disclosure further provides corresponding computer readable medium.

  • Publication number: 20220329530
    Abstract: Systems and methods to measure the number of packets in Control/User Plane Separation, CUPS, are provided. In some embodiments, a method performed by a Control Plane, CP, entity includes: determining that packet counting should be performed by a User Plane, UP, entity; providing measurement instructions to the UP entity for counting packets and identifying a recipient of a packet count if the CP entity is not the recipient; and, if the CP entity is the recipient of the packet count, receiving, from the UP entity, a packet count. In this way, a CP function is able to instruct a UP function to perform a measurement in terms of packets, e.g., a measurement of the number of packets transmitted.

  • Publication number: 20220304089
    Abstract: Embodiments of the present disclosure provide methods and apparatuses for session management. A method comprises receiving from a user equipment (UE) a request for establishing another session to a data network identified by a data network identification. At least one existing session of the UE has been established to the data network. The method further comprises checking whether the subscription data or the policy data for the UE includes a first indication which indicates that a same session management node for multiple sessions to the data network identified by the same data network identification is required. The method further comprises selecting the same session management node as the at least one existing session for the UE when the subscription data or the policy data includes the first indication. The method further comprises sending a session establishment request to the selected session management node.

  • Publication number: 20190260600
    Abstract: The invention relates to a Policy and Charging Enforcement Function (PCEF) and a method of the PCEF in a communications network of indicating to a Policy and Charging Rules Function (PCRF) charging information of a 5 subscriber received from an Online Charging System (OCS). The invention further relates to a PCRF and a method of the PCRF in a communications network of acquiring OCS charging information of a subscriber. In a first aspect, a method of a PCEF (20) in a communications network (10) of indicating to a PCRF (15) charging information of a subscriber (16) received from an OCS (21) is provided. The method comprises receiving (S102), from the OCS, the charging information of the subscriber requesting a service in the communications network, and submitting (S103), over Gx reference point to the PCRF, a Rule-Failure-Code associated with the charging information received from the OCS.
