Abstract: Techniques are disclosed for managing reauthentication and revocation in a communication network environment. In one example, a method comprises receiving, at a first network entity (e.g., an NSWOF), a request from a second network entity (e.g., a UDM) of a communication network to which user equipment is subscribed (e.g., HN), wherein the received request is for a reauthentication or a revocation of the user equipment in accordance with wireless local area network access. The first network entity identifies the user equipment based on information about the user equipment (e.g., UE context) previously stored by the first network entity. The first network entity sends at least a portion of the received request toward the user equipment, and then continues to participate in the reauthorization or revocation based on the request.

Abstract: Techniques for enhancing subscription authorization in a communications network are provided. For example, a method in a source network function service producer or an apparatus for a source network function service provider is disclosed. The method comprises: receiving a subscription request including access authorization information from a network function service consumer for a subscription to receive a notification upon occurrence of a specific event; verifying that the network function service consumer is authorized to create the subscription to the source network function service producer; storing subscription context and access authorization information granted for the subscription if the subscription request is authorized.

Abstract: Systems, methods, and software of performing a data repository service. In one embodiment, a data repository Network Function (NF) of a 5G core network is configured to receive a request from an NF service consumer for a service operation regarding storage of a record, and containing meta and/or one or more blocks of the record. The data repository NF is configured to apply encryption to one or more meta tags of the meta and/or to the blocks of the record based on one or more encryption indicators embedded in a meta schema defined for the meta, and to store the record with the one or more meta tags and/or the blocks in encrypted format according to the meta schema.

Abstract: Techniques for user consent in a communication network are disclosed. For example, a method comprises receiving, at a network entity of a communication network, a first level user consent for a first level data type for a first level purpose. The method further comprises applying, at the network entity, at least one hierarchical consent policy to the first level user consent to determine whether the first level user consent implies a second level user consent for a second level data type for a second level purpose.

Abstract: Systems, methods, and software of performing an Authentication and Key Management for Applications (AKMA) authentication service. In one embodiment, an AKMA element (1200) handles an enriched AKMA Key Identifier (A-KID) (800) having an identifier format with a username (802) and a realm (804) separated by an @-symbol (806). The username includes a Routing Indicator (RID) (812), an AKMA Temporary UE Identifier (A-TID) (814), and at least one supplemental character (810) that distinguishes the RID from the A-TID in the username The AKMA element performs a function of the AKMA authentication service based on the enriched A-KID.

Abstract: Techniques for preventing rogue network functions in a communication network are provided. For example, a method comprises obtaining information identifying one or more network entities suspected of malicious activity operating within the communication network, causing a re-authorization of the one or more network entities suspected of malicious activity, and in response to a re-authorization failure of at least one of the one or more network entities suspected of malicious activity, causing one or more remedial actions to occur within the communication network to prevent the at least one network entity that failed re-authorization from accessing other network entities in the communication network.
