Abstract: Various aspects described herein relate to apparatus, methods, and computer programs for retrieving an identifier of a subscription network of a mobile subscriber in a communication system. For example, one such method includes registering with a network repository function network function as a mobile number portability network function providing a service allowing a consumer to retrieve an identifier of a subscription network of a mobile subscriber. This method also includes receiving a request from the consumer to retrieve the identifier of the subscription network of the mobile subscriber. This method further includes sending a response to the consumer comprising information to retrieve the identifier of the subscription network of the mobile subscriber.

Abstract: According to an example aspect of the present invention, there is provided an apparatus configured at least to: receive, from a service communication proxy, a request for an access token which authorizes access to a service at a network function provider, transmit an authorization token to the service communication proxy, the authorization token being specific to the request, and provide the access token to the service communication proxy responsive to determining that a cryptographic signature of a network function consumer on a signed version of the authorization token, received in the apparatus from the service communication proxy, is correct. The apparatus may work in a network serving user equipments, for example.

Abstract: A method, apparatus, and computer program product provide for network communication error originator identification with a header, such as an HTTP header. In the context of a method, the method causes a service request from a NF client to be transmitted to a NF server via one or more intermediary network proxy functions. The method receives a service response with error information identifying the type or identity of the originator of the error response or identifying the type or identity of network proxy function having relayed the error response. The method may also be enabled to redirect a service request to a different NF server or a different network proxy function, and to enable the NF client to determine whether to redirect the request to a different NF server or a different network proxy function.

Abstract: An apparatus for performing: defining an authorization policy per UE, the authorization policy indicating which data are allowed to be accessed by which UE, configuring an authorization policy to one or more UE by providing a key material usable for validating an access token and information regarding the authorization policy indicating an allowance for connection between a requester UE and a producer element or a producer function with a valid access token or without an access token, receiving a request for authorization of a requester UE to access to specified data from a producer element or producer function, processing the request for authorization of the requester UE for deciding whether the request is allowed, and in case the request is allowed, obtain an access token for allowing access to the specified data from the producer element or producer function, and transmitting the access token to the requester UE.

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.
