Publication number: 20230209326Abstract: 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.Type: ApplicationFiled: June 29, 2020Publication date: June 29, 2023Inventors: Emiliano MERINO VAZQUEZ, Miguel Angel GARCIA MARTIN, Beatriz MAROTO GIL, David CASTELLANOS ZAMORA

Publication number: 20230171603Abstract: 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.Type: ApplicationFiled: May 12, 2021Publication date: June 1, 2023Inventors: Miguel Angel Garcia Martin, David Castellanos Zamora, Peter Hedman

Publication number: 20230156577Abstract: 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.Type: ApplicationFiled: March 5, 2021Publication date: May 18, 2023Inventors: Miguel Angel Muñoz de la Torre Alonso, Ulf Mattsson, Antonio Iniesta Gonzalez, Miguel Angel Garcia Martin, Maria Belen Pancorbo Marcos
