1. An operation and maintenance management method of a network slice subnet, comprising:
obtaining a correlation relationship of multiple service parameters of each network function, NF, with certain key performance indicators of the network slice subnet based on an analytical model; and taking the correlation relationship as a performance analysis result, wherein the performance analysis result is obtained by the analytical model in the NF, and the analytical model is obtained by multiple NFs and a common node based on federated learning;
obtaining multiple instantiated parameters in the network slice subnet corresponding to the multiple service parameters; and
optimizing certain NFs with the multiple instantiated or service parameters based on the correlation relationship;
wherein the correlation relationship of multiple service parameters of each NF with certain key performance indicators of the network slice subnet based on the analytical model, and taking the correlation relationship as the performance analysis result comprises:
obtaining a contribution degree of certain key performance indicators of each NF to the certain key performance indicators of the network slice subnet and a relationship of some multiple service parameters of each NF with its certain key performance indicators based on the analytical model; and
taking the contribution degree as the performance analysis result;
wherein the optimizing certain NFs with the multiple instantiated or service parameters based on the correlation relationship comprises:
determining a NF to be optimized based on the contribution degree to obtain information of the NF to be optimized; and
sending the information of the NF to be optimized to a network function virtual orchestrator (NFVO) of the network slice subnet, for the NFVO to initiate an optimal deployment of an NF instance or a new creation of the NF instance to a virtual network function (VNFM) based on the information of the NF to be optimized.
