A method for performing authorization for network function registration. The method includes instantiating a network function (NF) based on at least one micro-service; providing a software module with each of the at least one micro-service; sending, from each software module, an authorization code to a NF authorization platform, where the authorization code is associated with the micro-service; forwarding the at least one authorization code received at the NF authorization platform to an NF registration function (NRF); sending, from the NF, a service registration request to the NRF, where the service registration request includes each authorization code associated with the at least one micro-service; and registering the NF with the NRF, where the NRF validates each authorization code received from the NF.
