  • Publication number: 20240314027
    Abstract: A method implemented in a data collector node (DCN) is described. The DCN is configured to communicate at least with a network node and a data source node (DSN). The method includes determining a data collection coordination. The determined data collection coordination is associated with the DSN and includes determining whether any DCN is registered as a data collection coordinator of for the DSN. Upon determining there is no registered data collection coordinator of for the DSN, a request to register as the data collection coordinator of the DSN is transmitted to the network node. Upon determining the DCN is itself the data collection coordinator, data collection from the DSN is coordinated. Further, upon determining a second DCN is registered as the data collection coordinator, a subscription request for data collection from the DSN is transmitted to the second DCN.

  • Patent number: 12052657
    Abstract: A method performed by an Access and mobility Management Function (AMF) node for allocating a target network slice instance to serve a (PDU) session for a User Equipment (UE). The AMF node receives (501), from a Network Slice Selection Function (NSSF) node, information about a decision to change an allocation of a first network slice instance that is serving the PDU session to the target network slice instance, and an identifier of the target network slice instance. The AMF node then retrieves (502), from a first Session Management Function (SMF) node of the first network slice instance, a UE context related to the UE and the PDU session. The AMF node transmits (504), towards a target SMF node of the target network slice instance, information about the retrieved UE context and Access Network (AN) tunnel information to be used for the PDU session. The AMF node receives (505), from the target SMF node, target Core Network (CN) tunnel information to be used for the PDU session.

  • Publication number: 20240007903
    Abstract: A method implemented by a first network node in a telecommunication network is provided. The method includes: determining whether a background data transfer, BDT, policy is to be applied to a first core network, a second core network or both; and in response to the BDT policy being to be applied to both the first core network and the second core network, transmitting, to a second network node, a request for negotiating a common BDT policy for both the first core network and the second core network. If the negotiated BDT policy is applicable to both the first and the second core networks, the applicability of the policy is independent of network coverage, UE support for 5G, availability of the 5G subscription, and whether the UE sessions are handled by the PCF or the PCRF.

  • Publication number: 20230209326
    Abstract: A method, performed by a first node (111), for handling subscriptions in a communications network (100). The first node (111) operates in the communications network (100). The first node (111) sends (303), to a second node (112), a first indication. The first indication requests subscription to report new accessibility for a device (140) to a second domain different than a first domain currently accessible by the device (140). The first node (111) receives (304) a second indication from the second node (112). The second indication indicates the new accessibility by the device (140) to the second domain. A fifth node (115) receives (501), from the first node (111), a fifth indication indicating a notification of an event by the device (140) after the new accessibility has been enabled. The fifth indication is received based on a previous indication sent by the fifth node (115) prior to the new accessibility has been enabled.

  • Publication number: 20230171603
    Abstract: The present disclosure relates to provisioning of a UE with credentials to access a communication network, such as a SNPN. A DCS maintains a binding of UE onboarding credentials and a UE identifier with network information for the authorized SNPN. After obtaining the network information from the DCS, the onboarding network requests authorization from a provisioning server (190) in the SNPN to initiate a provisioning procedure with the SNPN. The provisioning server (190) verifies that the UE is authorized to access the SNPN and determines the type of provisioning procedure to use (e.g., control plane provisioning or user plane provisioning). If verification is successful, the provisioning server (190) sends a response authorizing the onboarding network to initiate provisioning of the UE and indicating the type of provisioning procedure to use. The authorization procedure prevents rogue or malicious UEs from attempting to initiate a provisioning procedure with the ANPN without prior authorization.

  • Publication number: 20230156577
    Abstract: Methods and apparatus are provided to enable a consumer network function (consumer NF) to discover instances of a NWDAF 90 co-located with NFs in the 5GC 30 of a communication network 10. Existing procedures and messages between NFs are leveraged to distribute lists of NWDAFs 90 co-located with a NF, such as a UPF 35, AMF 40 or SMF 45. A NF can provide a list of NWDAF instances for a particular UE 15 that are co-located with either the same NF or a separate producer NF when the communication procedure for the UE 15 is invoked. Over time, the consumer NFs build a database associating the co-located NWDAFs in other NFs with corresponding UEs 15 served by the consumer NF. When the consumer NF needs analytic data for one or more UEs 15 served by the consumer NF, the consumer NF can use a UE ID to look up the co-located NWDAFs for the UE 15 and subscribe with the co-located NWDAF instances to receive analytics data for the UE 15.
