1. A method performed by a network repository function (NRF) server for limiting a scope of authorization provided to a network function (NF)-service consumer (NFC) device in a wireless network, the method comprising:
receiving, by the NRF server, an NF-registration request message from a NF-service producer (NFP) device,
wherein the NF-registration request message comprises:
a first information element indicating a single-network slice selection assistance information (S-NSSAI) of the NFC device allowed to access by the NFP device,
a corresponding second information element indicating operations allowed on resources of the NFP device belonging to at least one S-NSSAI of the NFP device, and
a third information element indicating a trust-level of the NFC device, the trust-level relating to an access rule specifying a scope of access allowed for the NFC device, wherein the trust-level is used for limiting an amount of information provided to the NFC device; and
registering a profile of the NFP device based on at least one of the first information element, the second information element, or the third information element.
