Abstract: According to an example aspect of the present invention, there is provided an apparatus configured at least to determine whether a cryptographic signature of a token received in the apparatus from a network function consumer is valid, obtain a cryptographic signature of the apparatus of the token responsive to the cryptographic signature of the token being valid, and provide the token to a peer entity of the apparatus, wherein the cryptographic signature of the apparatus is either included into the token or provided in a header external to the token, wherein the peer entity is comprised in a second network, different from a first network where the apparatus is comprised in. The request may serve a user equipment, directly or indirectly.

Abstract: There are provided measures for optimization of network function profile administration and discovery. Such measures exemplarily comprise, at a network entity in a network entity composition, transmitting, towards a network repository function, a network entity registration request including an identifier of said network entity, an identifier of said network entity composition, and network entity specific attributes of said network entity, and receiving a network entity registration response indicative of a result of said network entity registration request.

Abstract: Systems, methods, apparatuses, and computer program products for enhancing shared data in a communications system are provided. One method may include receiving or retrieving, at a service consumer, shared data from a service producer. The shared data may include at least one treatment attribute configured to indicate a treatment of at least one attribute in the shared data with respect to at least one attribute in individual subscriber data. The method may also include applying a value provided in the at least one shared data attribute or a value provided in the at least one individual subscriber data attribute based on the at least one treatment attribute.

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: Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for inter-network communication. A first edge protection proxy in a first network receives a request for an access token from a network repository function in the first network. The access token is to be used by a first network function in the first network to request a service from a second network function in a second network. The first edge protection proxy validates the request based on configurations allowed to access services provided by networks different from the first network. If the validation of the request is successful, the first edge protection proxy transmits the request to a second edge protection proxy in the second network. The transmitted request comprises verified information concerning the first network function.
