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.

Abstract: For example, within a communication network environment a possibility for retrieval of historical data indicative of events occurring within the communication network environment and obtained from one or more data sources within the communication network environment is provided. Selection criteria is specified at a first device to be applied to the historical data for a query to be performed on the historical data kept in a historical data repository associated with a second device. At least one processing instruction is specified at the first device. The processing instruction determines the generation of a report based on the defined query. The selection criteria and the processing instruction is transmitted to the second device, and the report generated at the second device based on the transmitted selection criteria and processing instruction is received.
