  • Patent number: 12634786
    Abstract: Apparatuses and methods for policy based selection of a network. In one embodiment, a method implemented in a user equipment (UE) includes obtaining a transfer policy from a policy node of a first network, the transfer policy being associated with a network selection for an application; and determining whether the application is to be transferred from using the first network to using a second network based at least in part on the obtained transfer policy, the first network being one of a standalone non-public network, SNPN, and a public land mobile network, PLMN and the second network being another one of the SNPN and the PLMN and the transfer policy being based at least in part on at least one of: (i) Quality-of-service, QoS, information associated with the application and (ii) whether the UE has a subscription to the second network.

  • Patent number: 12593209
    Abstract: A data management network node (12) is configured for use in a wireless communication network (10). The data management network node (12) stores subscription data (14) for a wireless device (16). The data management network node (12) receives, from network equipment (26), a request that requests subscription data (14) for the wireless device (16). Responsive to the request, the data management network node (12) transmits to the network equipment (26) a response that includes at least some of the stored subscription data (14). If the subscription data (14) included in the response indicates the wireless device (16) is subscribed to use a certain data network or network slice that is subject to secondary or slice-specific access control, the subscription data (14) included in the response includes a least one generic subscription identifier for the wireless device (16).

  • Patent number: 12587955
    Abstract: A mechanism is provided to monitor and control the number of terminals (100) or number of PDU sessions for a network slice, or both. A new network function called the Network Slice Control Function (NSCF) (85) is defined that interacts with an Access and Mobility Management Function (AMF) (40) and/or Session Management Function (SMF) (45) to monitor and control a number of users for a network slice, a number of PDU sessions for a network slice, or both. The NSCF (85) determines per slice quotas for the number of users and/or number of session for network slices and interacts with the AMF (40) and/or SMF (45) to enforce the quotas.

  • Patent number: 12375990
    Abstract: A method performed by a Radio Access Network (RAN) node for handling a service request from a User Equipment, UE, in a wireless communications network. The RAN node supports a first network slice in a first Area, A1. The RAN node connects (902) to the UE via A1. The RAN node sends (903) to a Core Network (CN) node, a service request from the UE. The service request relates to one or more network slices that the UE requests in a certain Area. The RAN node receives (904) an indication from the CN node. The indication indicates the one or more network slices requested by the UE together with any one or more out of: —A list of network slices that are allowed to be accessed by the UE in the current A1, and—an indication of a new area priority policy associated to the one or more network slices that are requested by the UE. The RAN node decides (905) how to handle the service request from the UE based on the indication received from the CN node.

  • Patent number: 12356322
    Abstract: During PDN connection establishment in the EPC, a UE and a session management entity (SME) (e.g., PGW-C+SMF) exchange information. In case the SME supports more than one S-NSSAI, before the SME provides an S-NSSAI to the UE, the SME should check such that the selected S-NSSAI is among the UE's subscribed S-NSSAIs by retrieving the Subscribed S-NSSAI from a UDM using, for example, the Nudm_SDM_Get service operation.

  • Publication number: 20250220534
    Abstract: Systems and methods for controlling the use of a network slice in a core network of a cellular communications system are disclosed. In one embodiment, a method comprises, at a first Network Function (NF) in a core network of a cellular communications system, sending, to a second NF associated with a first network slice, a first message that initiates transfer of one or more Protocol Data Unit (PDU) sessions of a User Equipment (UE) from the first network slice to a second network slice. The method further comprises, at the second NF, receiving the first message from the first NF and sending, toward the UE, a session management message that causes the transfer of the one or more PDU sessions of the UE from the first network slice to the second network slice.

  • Publication number: 20250212103
    Abstract: A method performed by a core network node is provided. The method is for handling one or more rules for a User Equipment, UE, in a network. The core network node is operating in the network. The network is comprised in a wireless communications network. The core network node receives (201) capability data from the UE. The capability data relates to the UE's capabilities to support rules for use of one or more network slices. The core network node obtains (203) one or more rules relating to a use of one or more network slices allowed in the network. The core network node decides (204) that the UE is capable to support rules for use of one or more network slices in the network according to the one or more rules, based on the received capability data and the obtained one or more rules. The core network node sends (205) to the UE, the one or more rules that the UE is capable to support, and where the one or more rules are to be applied by the UE for use of one or more network slices in the network.
