Abstract: The present specification faces the issues of selecting a right 5G Network Function, NF, instance in scenarios wherein NF instances are considered NF segments that manage different sets of users and wherein NF segmentation is not based on SUPI ranges. To solve these issues, there is provided a new procedure for accessing an NF segment, wherein registration and discovery of the right NF segment is based on a Routing Indicator, and wherein the Routing Indicator, which is received with a Subscription Concealed Identifier (SUCI) identifying a UE, is included in any interaction between 5GC NFs.

Abstract: A method of initiating a Packet Data Unit, PDU, session between an User Equipment, UE, and a Data Network Name, DNN, in a telecommunication network, said method comprising the steps of; receiving, by an Access & Mobility Function, AMF, a registration request for an UE for registering said UE in said telecommunication network, retrieving, by said AMF, from an Unified Data Management, UDM, node, one or more DNNs to which PDU sessions are expected to be established by said UE in said telecommunication network, and wherein said step of retrieving is triggered by said receiving of said registration request, instructing, by said AMF, said UE to initiate said one or more PDU sessions between said UE and said one or more DNNs. Complementary methods and Devices for performing a method according to the invention are also presented herein.

Abstract: A technique is disclosed for synchronizing first and second data sets stored in a data repository. A method includes triggering, by the data repository, in response to a commit order relating to an ongoing transaction requested by a client and instructing the data repository to apply data modification(s) on the first data set, transmission of a notification event message relating to the ongoing transaction to a data consistency controller. The method includes receiving, by the data repository, a notification event response message relating to the ongoing transaction from the data consistency controller, the notification event response message indicating to the data repository whether (i) to commit the data modification(s) instructed by the commit order on the first data set and corresponding data modification(s) on the second data set, or (ii) to roll back the data modification(s) instructed by the commit order on the first data set.

Abstract: A user equipment (18) is configured to receive an extensible authentication protocol, EAP, request (28) from a session management function, SMF, (14) that serves as an EAP authenticator for secondary authentication of the user equipment (18). The secondary authentication is authentication of the user equipment (18) in addition to primary authentication of the user equipment (18). The user equipment (18) is also configured to, responsive to the EAP request (28), transmit an EAP response (30) to the SMF (14).

Abstract: Being aware of a loss of signalling bearer transport through an IP Connectivity Access Network is an important issue. Therefore, the present invention relies on amending the Policing and Charging Control model with means to provide the IMS infrastructure with subscriptions to and notifications about signalling session events detected on the signalling IP flow transported through the bearer layer. To this end, a P-CSCF, or AF included therein, is amended to allow the establishment of a signalling session for subscription to notification of bearer level events for a signalling IP flow. Apart from that, new processing rules are required at the AF and PCRF for handling the signalling session, the notification of events and the termination of the signalling session.

Abstract: Exemplary embodiments include a method for provisioning subscription data, for a plurality of subscribers, to one or more network functions, NFs, in a communication network. Such embodiments include storing group data, related to the plurality of subscribers, in association with at least a first group identifier, GID, but not in association with individual subscription data for the respective subscribers. Such embodiments also include sending, to the one or more NFs, the group data and the first GID. Such embodiments also include sending, to a particular one of the NFs, the first GID and individual subscription data for a particular one of the subscribers. Embodiments also include complementary methods performed by network functions that receive subscription data in this manner, as well as various network functions and/or nodes, in a communication network, that are configured to perform various disclosed methods.

Abstract: A network node operates a Session Management Function (SMF) in a control plane of a core network of a wireless network. The network node authenticates a User Equipment (UE) with an Extensible Authentication Protocol (EAP) server in a secondary authentication process that uses the SMF as an EAP authenticator. The EAP server is outside of the core network and the UE is separately authenticated with a further network node in the control plane of the core network via a primary authentication process. Authenticating the UE in the secondary authentication process comprises exchanging EAP messages between the SMF and the UE and between the SMF and the EAP server. The SMF authorizes a data session between the UE and the external network through a user plane of the core network based on the UE having successfully authenticated via both the primary authentication process and the secondary authentication process.
