Claim 18:
19. A system, comprising:
a first network function network element, comprising:
one or more first processors; and
a first memory coupled to the one or more first processors and configured to store first computer-executable instructions that, when executed by the one or more first processors, cause the first network function network element to send a first request message, wherein the first request message requests permission to invoke a first network function service provided by a second network function network element, and wherein the first request message carries an identifier of the first network function network element, at least one of an identifier of the second network function network element or a type of the second network function network element, and an identifier of the first network function service; and

an authorization network element, comprising:

a second memory coupled to the one or more second processors and configured to store second computer-executable instructions that, when executed by the one or more second processors, cause the authorization network element to:
receive the first request message from the first network function network element;
determine that the first network function network element has the permission to invoke the first network function service;
generate a token, wherein the token comprises the identifier of the first network function network element, the at least one of the identifier of the second network function network element or the type of the second network function network element, and the identifier of the first network function service; and
