    Abstract: A method comprising: at a network function (NF) repository function (NRF) of a core network that includes a consumer NF and a producer NF: issuing, to the consumer NF, an access token used to access services of the producer NF based on allowed authorization attributes of the producer NF; before expiry of the access token, receiving, from the producer NF, an update message that indicates retiring authorization attributes of the allowed authorization attributes, and storing the retiring authorization attributes; before the expiry of the access token, upon receiving, from the consumer NF, an access token request for a new access token, determining not to authorize the access token request based on the retiring authorization attributes; and based on determining, sending, to the consumer NF, an access token error to enable the consumer NF to migrate service requests to a new producer NF before the expiry.
