1. A method of operating a network data analytics functions, NWDAF node in a communication network, to evaluate whether to scale a first resource of a network slice of the communication network, the method comprising:
receiving, from a network function virtual operator, NFVO, node of the communication network, a first message indicating a request for approval to scale the first resource of the network slice;
responsive to receiving the first message, determining whether to scale the first resource of the network slice based on information regarding a second resource, wherein the first and second resources are of different types; and
transmitting, to the NFVO node, a second message indicating whether to scale the first resource of the network slice based on determining whether to scale the first resource of the network slice.
