In an embodiment, the method (600) may comprise the step of transmitting (S601) a subscription message comprising at least one of Data Network Name (DNN) of a data network and Single Network Slice Selection Assistance Information (S-NSSAI) to a second network function (102) implementing network exposure function, so as to monitor an event status for a User Equipment (UE) or a group of UEs. In an embodiment, the method (600) may further comprise the step of receiving (S602) a notification message comprising information indicating the event status from the second network function (102). The embodiments herein allow the application function to subscribe PDN_CONNECTIVITY_STATUS event or other monitoring events (such DOWNLINK_DATA_DELIVERY_STATUS event) for a specific data network or 5G virtual network via Nnef_EventExposure_Subscribe service operation, for a single UE, a group of UE or any UE.

Abstract: The embodiments herein relate to report of the Single Network Slice Selection Assistance Information (S-NSSAI) that is associated with the Protocol Data Unit Session to Data Network Authentication Authorization Accounting (DN-AAA) server. In an embodiment, there proposes a method (300) performed by a first network function (101) implementing DN-AAA server. In an embodiment, the method may comprise the step of receiving (S301, S302), from a second network function (102), arequest message comprising network slice related information for a PDU Session. In an embodiment, the request message may be access request message for authentication at least based on the network slice related information. In another embodiment, the request message may be accounting request message indicating that the PDU session has started. With embodiments herein, the DN-AAA server (101) may know the network slice information that is associated with the session for authentication and statistics based on the received Session S-NSSAI information.

Abstract: Embodiments of the present disclosure relates to a method, and an apparatus for service level agreement assurance in mobile network. The method (100) performed by the first network node may comprise: obtaining (S101) service data from an AF for a service or an application, and network data from at least one core network node; analyzing (S102) the service data and the network data to obtain perceived and/or predicted information about the service experience for the service or the application; predicting (S103) information about quality of service, QoS, based at least on the perceived and/or predicted information about service experience; and transmitting (S104) the perceived and/or the predicted information about the service experience and/or the predicted information about the QoS, to a second network node and/or the AF. According to embodiments of the present disclosure, less impact on the user accessibility may be caused while trying to assure service level agreement, SLA, in the mobile network.

Abstract: Embodiments of the present disclosure provide method and apparatus for authentication. A method performed by a session management and gateway entity comprises receiving a create session request comprising an identity of a terminal device from a mobile management entity. The method further comprises determining to use a second authentication method rather than a first authentication method. The second authentication method has a higher security than the first authentication method. The method further comprises triggering a procedure of the second authentication method related to an authentication authorization and accounting (AAA) server.

Abstract: The present disclosure provides methods, network nodes, and computer readable media for dynamically discovering a serving network node in a core network. The method at an NEF includes: receiving a service request message for the Ethernet type session from an AF, wherein the service request message comprises network related identification information for the Ethernet type session; and discovering, based on the network related identification information, a BSF that holds binding information of a PCF for the Ethernet type session.

Abstract: The embodiments herein relate to optimized procedure for Packet Flow Description (PFD) management. In one embodiment, there proposes a method (800) for managing Packet Flow Description (PFD), comprising: receiving (S801) from a Session Management Function (SFM) (201) or a User Plane Function (UPF) (302) a demand message indicating the demand for at least one PFD rule for an application; detecting (S802) the at least one PFD rule for the application; and notifying (S803) information regarding the at least one PFD rule to the SMF (201) or the UPF (302). The embodiments herein may achieve an optimized procedure for PFD Management which optimizes the delivery of PFD rules, by reducing the amount of signaling and by reducing the number of hops between the producer (AF) and the consumer (UPF).

Abstract: Periodic requests for to Packet Flow Description, PFD, data updates on all Application Ids generate a constant background load in several network function nodes, even if applications have not been updated. There is provided a mechanism to optimize PFD management updates in a telecommunication network, whereby PFD data for a selected number of applications are stored and updated permanently, whilst PFD data for other applications are only temporarily stored so that storage and updates are released when these other applications are not in use. A list of permanent Application Ids is configured for the most frequently used applications. When a control rule specifies an Application Id not included in the list of permanent Application Ids, the specified Application Id is included in a list of temporary Application Ids, which are periodically checked and, when not used, are removed from the list of temporary Application Ids.
