Communication method and apparatus for plurality of administrative domains

A communication device, comprising:

• at least one processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the at least one processor to cause the communication device to:
• send a subscription request message for analysis and prediction information of a nested network service (NS) instance to a nested network functions virtualization orchestrator (NFVO), wherein the subscription request message carries an identifier of the nested NS instance, a type of the analysis and prediction information, and analysis dimension information corresponding to the analysis and prediction information;
• receive a subscription response message returned by the nested NFVO;
• receive a notification message that is sent by the nested NFVO and that carries the analysis and prediction information of the nested NS instance, wherein the analysis and prediction information is generated by the nested NFVO after performing data analysis on the nested NS instance in the analysis dimension based on the type of the analysis and prediction information;
• and
• perform a management operation based on the received analysis and prediction information.

A method, comprising:

• receiving, by a nested network functions virtualization orchestrator (NFVO) from a composite NFVO, a subscription request message for analysis and prediction information of a nested network service (NS) instance, wherein the subscription request message carries an identifier of the nested NS instance, a type of the analysis and prediction information, and analysis dimension information corresponding to the analysis and prediction information, and wherein a plurality of administrative domains comprise a composite NS administrative domain and a nested NS administrative domain, the composite NS administrative domain and the nested NS administrative domain each comprise the composite NFVO and the nested NFVO;
• sending, by the nested NFVO, a subscription response message to the composite NFVO;
• and
• sending, by the nested NFVO, a notification message that carries the analysis and prediction information of the nested NS instance, wherein the analysis and prediction information is generated by the nested NFVO after performing data analysis on the nested NS instance in the analysis dimension based on the type of the analysis and prediction information.
