There is provided mechanisms for enabling selection of service-providing NFs in a 3GPP communication network. A method is performed by an NRF. The method comprises obtaining one register request from each of the service-providing NFs. Each registration request comprises an NF profile. Each NF profile comprises a security setting attribute. The method comprises storing the NF profiles of the service-providing NFs. The method comprises obtaining a discovery request from a service-requesting NF. The request indicates an NF type. The method comprises providing a discovery response to the service-requesting NF. The discovery response comprises the NF profile of at least one of the service-providing NFs of the NF type, thereby enabling selection of the service-providing NFs. The security setting attribute may pertain to support for mutual TLS and/or for use of OAuth-2 based authorization.

Selection of service-providing network functions in a 3GPP communication network

A network repository function, NRF, in a core network domain of a mobile communication network is provided, wherein the NRF is configured to register network function, NF, profiles for NF discovery, and wherein NF certificates have been issued to the NFs, each NF certificate including a public key of the respective NF and at least one signature of at least one certification authority, CA. The NRF is configured to receive, from a registering NF having an NF certificate, profile information comprising an NF identity of the registering NF, an NF type of the registering NF, and at least one CA certificate of at least one CA that signed the NF certificate issued to the registering NF. The NRF is further configured to store the received profile information in a repository.
