  • Publication number: 20240121740
    Abstract: In response to receiving from a requesting entity (2) a request for a connection to an entity providing a service in an edge data network (4), a first server (7) attempts to identify a second server (5) located in the edge data network (7) based on at least one selection criterion. If the second server (4) cannot be identified or is not available, the first server (7) identifies a second alternative server that is different from the second server, or identify a first alternative server that substitutes for the first server (7) for attempting to identify the second server. This can contribute, for example, to mitigating the impact of failing to discover one or more preferred edge servers for a User Equipment (UE).

  • Publication number: 20240107424
    Abstract: In response to receiving from a requesting entity (2) a request for a connection to an entity providing a service in an edge data network (4), a first server (7) attempts to identify a second server (5) located in the edge data network (7) based on at least one selection criterion. The at least one selection criterion includes a congestion state of a server located within the edge data network (4). If the second server (5) is identified, the first server (7) sends information about the second server (5) to the requesting entity (2). If the second server (5) cannot be identified, the first server (7) sends to the requesting entity (2) a rejection message indicating that the second server (5) cannot be identified. This can contribute, for example, to providing a suitable selection criterion for identifying an edge server.

  • Publication number: 20230379810
    Abstract: A UE (1) receives, from a network (9, B), control information indicating an association of each of at least one Closed Access Group (CAG) ID with at least one network slice identifier. The UE (1) performs cell selection or cell reselection using the received control information. This allows the UE to take into account the availability of a network slice in cell selection and cell reselection in the case of a Public network integrated Non-Public Network (PNI-NPN), for example.

  • Publication number: 20230337122
    Abstract: A core network node (3) stores a first association between a plurality of Home PLMN S-NSSAIs and a Serving PLMN S-NSSAI. The first association includes a second association between the Serving PLMN S-NSSAI and a Home PLMN S-NSSAI that is not subject to NSSAA, and a third association between the Serving PLMN S-NSSAI and another Home PLMN S-NSSAI subject to NSSAA. If a UE (1) does not support NSSAA feature and if a part of multiple Home PLMN S-NSSAIs presented by the UE (1) is included in the second association and the rest is included in the third association, the core network node sends information containing the second association to the UE (1). This can allow, for example, proper notification of information about a Mapped S-NSSAI available to a UE that does not support NSSAA.

  • Publication number: 20230276351
    Abstract: An AMF apparatus (2) receives, from a terminal (1), a registration request message including first information indicating support for a restriction feature related to simultaneous use of network slices. The AMF apparatus receives, from a UDM apparatus (8), terminal subscription information including second information that indicates a restriction related to simultaneous use of network slices. Upon receiving the first information and the second information, the AMF apparatus (2) sends, to the terminal (1), a registration accept message including a Single Network Slice Selection Assistance Information (S-NSSAI) and third information. The third information is included in the terminal subscription information and indicates for the S-NSSAI a restriction related to simultaneous use of network slices. This can contribute, for example, to achieving registration management adapted to various restrictions on the use of network slices.

  • Patent number: 11510139
    Abstract: An AMF node (2) manages a UE context regarding a UE (1). The UE context includes a) a set of allowed network slice identifiers indicating one or more network slice identifiers currently allowed to the UE (1), and b) a set of pending network slice identifiers indicating one or more network slice identifiers for which a Network Slice-Specific Authentication and Authorization (NSSAA) procedure is pending. If the AMF (2) triggers initiation of a re-authentication and re-authorization procedure for a first network slice identifier currently allowed to the UE (1), it removes the first network slice identifier from the allowed set and store the same in the pending set. This, for example, allows the AMF to manage the UE context appropriately.
